- fail when copying files into lib/uniwidth/.
- * src/output.c (prepare_symbols): When writing yytname muscles, where
- symbol names will be encoded in C-string literals, tell quotearg to
- escape trigraphs. This used to be the default in gnulib.
- * tests/regression.at (Token definitions): Because of the change in
- gnulib's quotearg behavior, string_as_id in parse-gram.y no longer
- escapes trigraphs in symbol names. Thus, yytname no longer has
- trigraphs unnecessarily doubly escaped. Update test case output.
- Extend test case to be sure Bison's own error messages will no longer
- have trigraphs in symbol names unnecessarily escaped once.

-
- Improve handling of multiple S/R conflicts in the same state and of S/R
- conflicts involving multiple reductions.
- * src/conflicts.c (resolve_sr_conflict): Don't assign the error action
- set for a state here or Bison will abort if it is reassigned on a
- later conflicted reduction in the same state.
- Similarly, don't finalize and assign the solved conflicts report here
- or it will be lost if it is reassigned on a later conflicted reduction
- in the same state.
- (set_conflicts): Instead, assign them both here after all S/R conflicts
- in the state have been fully examined.
- * src/print.c (shift_set): Rename to...
- (no_reduce_set): ... this.

- reduction on an error action token, the reduction is enclosed in
- brackets.

- * tests/conflicts.at (Solved conflicts report for multiple reductions
- in a state): New test case.

-
- Fix C++ test cases after recent Gnulib changes. Discussed starting at
- <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00000.html>.
- * examples/calc++/Makefile.am (DEFAULT_INCLUDES): Override Automake's
- definition in order to avoid Gnulib headers since we don't use config.h
- here.
- * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Use AT_DATA_GRAMMAR
- rather than AT_DATA so that config.h is included.
-
-2007-07-01 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * data/glr.c (yy_yypstack, yypstates, yypdumpstack): Use YYFPRINTF
- instead of fprintf. Guard these functions with #if YYDEBUG instead of
- #ifdef YYDEBUG for consistency with all other uses of YYDEBUG in Bison
- and so that YYFPRINTF is guaranteed to be defined here.
-
-2007-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
-

- is required for this function to behave correctly.
- * src/closure.h (closure): Mention sorting.
-
-2007-05-28 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * src/lalr.c (state_lookahead_tokens_count): For code readability,
- move the check for disabled transitions to an aver since conflict
- resolution hasn't happened yet.
-
- * src/lalr.c (state_lookahead_tokens_count): Remove the check that
- labels a state as inconsistent just because it has error transitions.
- The original form of this check appeared in revision 1.1 of lalr.c,
- which was committed on 1991-12-21. Now (at least), changing the
- consistency label on such a state appears to have no useful effect in
- any of the places it is examined, which I enumerate below. The key
- point to understanding each item in this enumeration is that a state
- with an error transition is labelled consistent in the first place only
- if it has no rules, so the check cannot matter for states that have
- rules. (1) Labelling a state as inconsistent will cause set_conflicts
- to try to identify its conflicts, and a state must have *rules* to have
- conflicts. (2) Labelling a state as inconsistent will affect how
- action_row sets the default *rule* for the state. (3) Labelling a
- state as inconsistent will cause build_relations to add lookback edges
- to *rules* in that state.
- * src/state.h (struct state): Word the comment for member consistent
- more carefully.

- Enable the Java related testsuite tests when the only Java compiler
- found is a gcj < 4.3. Discussed at
- <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00016.html>.
- * configure.ac (gt_JAVACOMP): Don't specify a target_version.
-
-2007-02-11 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * data/Makefile.am: Update copyright date.
- * data/push.c (yypull_parse): Report memory exhaustion and return 2 if
- yypstate_new returns NULL.
- (yypstate_new): Return NULL if malloc does.
- * src/reader.c (packgram): Move translation of rule actions from the
- beginning of packgram to...
- (check_and_convert_grammar): ... here right before packgram is invoked
- so it's easier to write more complete comments, and remove redundant
- code.
-
-2007-02-10 Joel E. Denny <jdenny@ces.clemson.edu>
-
- As in semantic actions, make @$ in %initial-action, %destructor, and
- %printer imply %locations.
- * src/scan-code.l (SC_SYMBOL_ACTION): Set locations_flag = true when
- scanning @$.
- * tests/actions.at (AT_CHECK_ACTION_LOCATIONS): New macro supporting...
- (@$ in %initial-action implies %locations,
- @$ in %destructor implies %locations,
- @$ in %printer implies %locations): ... these new test cases.
-
-2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
-
- Undo most of the 2007-02-03 change, switching to the strcase module
- now that gnulib strcase has been fixed.
- * bootstrap.conf (gnulib_modules): Remove c-strcase. Add strcase.
- * lib/.cvsignore: Remove c-ctype.c, c-ctype.h, c-strcase.h,
- c-strcasecomp.c, c-strncasecmp.c. Add strcasecmp.c, strncasecmp.c
- * m4/.cvsignore: Add strcase.m4.
- * src/getargs.c: Revert 2007-02-03 change, as follows.
- Don't include c-strcase.h.
- (language_argmatch): Use strcasecmp rather than c_strcasecmp.
- strcasecmp has "unspecified behavior" outside the POSIX locale,
- but it works fine in practice if at least one argument is ASCII,
- as is the case in Bison.
-
-2007-02-07 Paolo Bonzini <bonzini@gnu.org>
-
- * tests/java.at: Skip tests if only one of javac/java is present.
- Reported by Joel E. Denny.
- * tests/atlocal.in: Adjust copyright years.
-
-2007-02-05 Paolo Bonzini <bonzini@gnu.org>
-
- * data/lalr1.java (Stack): Work around old verifiers that disallow
- access to the private fields of an inner class, from the outer class.
- We can make Stack's fields public because user code doesn't have access
- to the instance of Stack used by parse(). Reported by Paul Eggert.
-
-2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
-
- * .cvsignore: Add javacomp.sh, javaexec.sh. Is this really
- the right spot for these files?
- * bootstrap.conf (gnulib_modules): Add c-strcase.
- * lib/.cvsignore: Add c-ctype.c c-ctype.h, c-strcasecomp.c,
- c-strncasecmp.c.
- * src/getargs.c: Include c-strcase.h.
- (language_argmatch): Use c_strcasecmp rather than strcasecmp,
- to avoid unspecified behavior.

-
- Clean up.
- * src/scan-skel.l (at_directive_perform): Add at_directive_argc and
- at_directive_argv arguments so these no longer have to be global
- variables. Also, update the implementation for the following changes.
- (fail_for_at_directive_too_many_args,
- fail_for_at_directive_too_few_args): Add at_directive_name argument.
- (at_directive_name): Remove as at_directive_argv[0] will be used for
- this now.
- (AT_DIRECTIVE_ARGC_MAX): Increment to make space in at_directive_argv
- for the directive name.
- (at_directive_argc, at_directive_argv): Make these local within
- skel_lex instead of global.

- (scan_skel): Move yylex_destroy to...
- (skel_scanner_free): ... here.
- * tests/skeletons.at (installed skeleton file name): Rename to...
- (installed skeleton file names): ... this.
-
-2007-01-27 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * ChangeLog: For changes in doc/bison.texinfo, consistently reference
- node names: say "Table of Symbols" not "Bison Symbols", and say "Decl
- Summary" not "Directives".
- * doc/bison.texinfo (Decl Summary, Calc++ Parser): Cross-reference the
- %code entry in "Decl Summary" rather than the one in "Table of Symbols"
- since the former is now the more complete one.
- (Prologue Alternatives): Likewise and do the same for %defines.
- (Table of Symbols): Add summary of %code, add summary of %define, and
- move full %code documentation to...
- (Decl Summary): ... here for consistency with other entries in these
- sections.
- Move %define entry in order to keep this list alphabetized.
- Reword %define entry a little to put less emphasis on the skeleton
- concept, which most users shouldn't have to think about.
-
-2007-01-26 Paul Eggert <eggert@cs.ucla.edu>
-
- Adjust to recent gnulib changes.
- * lib/.cvsignore: Remove stpcpy.h, strndup.h, strnlen.h.
- Add string.h, string_.h, unistd_.h, wchar_.h.
- * m4/.cvsignore: Add gnulib-common.m4, string_h.m4, wchar.m4.
- * src/system.h: Don't include <stpcpy.h>; this is now done by

-
-2007-01-23 Paolo Bonzini <bonzini@gnu.org>
-
- Simplify implementation of unqualified %code, implement macros for

-2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Implement support for relative and absolute skeleton file names.
- Discussed starting at
- <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00071.html>.
- * doc/bison.texinfo (Decl Summary): Document in %skeleton entry.
- (Bison Options): Document in --skeleton entry.
- * src/output.c (output_skeleton): Use strncpy rather than strcpy since
- full_skeleton can't necessarily hold all of pkgdatadir.
- If the specified skeleton file name contains a `/', don't prepend
- pkgdatadir.
- * src/parse-gram.y (prologue_declaration): If the specified skeleton
- file name contains a `/', prepend the grammar file directory.

-2007-01-16 Akim Demaille <akim@epita.fr>
-
- * doc/bison.texinfo (Calc++ Parsing Driver): Let "parse" return an
- error code.
- (Calc++ Scanner): Exit with failure if we can't open the input
- file.
- Accept "-" standing for stdin.
- (Calc++ Top Level): Print the result only if the parsing was
- successful.
-
-2007-01-16 Akim Demaille <akim@epita.fr>

-
-2007-01-15 Paolo Bonzini <bonzini@gnu.org>
- and Joel E. Denny <jdenny@ces.clemson.edu>
-
- Clean up %define and %code implementation in M4 some. Most
- importantly, rename all related macros to be in the b4_percent_define
- and b4_percent_code namespaces. Also, complete support for `.' in
- %define variable names and %code qualifiers.
- * data/bison.m4 (b4_check_user_names): Check for special
- "SKELETON-NAMESPACE(name)" macros instead of using two nested
- m4_foreach loops.
- (b4_get_percent_define, b4_get_percent_code): Rename to...
- (b4_percent_define_get, b4_percent_code_get): ... these.
- Extend documentation with examples.
- For SKELETON-NAMESPACE (as documented for b4_check_user_names), use
- b4_percent_define_skeleton_variables and
- b4_percent_code_skeleton_qualifiers.
- Expect any value for the %define variable `foo' to be stored in the
- macro named `b4_percent_define(foo)'; expect any %code blocks for the
- qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
- expect any unqualified %code blocks to be stored in a macro named
- `b4_percent_code_unqualified'.
- Use m4_indir so that %define variable names and %code qualifiers can
- contain `.', which is allowed by the grammar parser.
- (b4_percent_define_default): New macro to set a default value for a
- %define variable.
- (m4_wrap): Update wrapped code, and fix some underquoting.
- (b4_check_user_names_wrap): Update and define outside the m4_wrap.
- Expect grammar uses of %define variables and %code qualifiers to be
- defined in b4_percent_define_user_variables and
- b4_percent_code_user_qualifiers.
- * data/c++.m4: Use b4_percent_define_default rather than
- m4_define_default. Fix some underquoting. Skeleton usage of %define
- variable define_location_comparison now implies skeleton usage of
- %define variable filename_type.
- * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
- data/push.c, data/yacc.c: Update macro names.
- * src/parse-gram.y (prologue_declaration, grammar_declaration): Update
- muscle names.
-
-2007-01-14 Juan Manuel Guerrero <juan.guerrero@gmx.de>
-
- DJGPP specific issues.
-
- * djgpp/config.site: Set ac_cv_path_mkdir to a sane DJGPP specific
- default. Set gl_cv_absolute_wctype_h to a sane DJGPP specific default.
-
-2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * tests/glr-regression.at: Use AT_PARSER_CHECK rather than AT_CHECK to
- run parsers in all tests so that Valgrind is invoked during
- maintainer-check-valgrind.
- (Duplicate representation of merged trees): Free all semantic values.
- (Duplicated user destructor for lookahead): Likewise.
-
-2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * tests/local.at (AT_PARSER_CHECK): Add a PRE argument to specify a
- command-line prefix.
- * tests/torture.at (Exploding the Stack Size with Alloca): Stderr is
- ignored, so use that PRE to set --log-fd=1 in VALGRIND_OPTS so we don't
- miss Valgrind messages.
- (Exploding the Stack Size with Malloc): Likewise.
-
-2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Ignore YYSTACK_USE_ALLOCA for push parsers since the stacks can't be
- locals. Reported by Juan Manuel Guerrero at
- <http://lists.gnu.org/archive/html/bug-bison/2007-01/msg00000.html>.
- * data/push.c: Enclose the #ifdef YYSTACK_USE_ALLOCA in b4_push_if.
- Fix some indentation also.
- * tests/torture.at (Exploding the Stack Size with Alloca): Add comment
- explaining this issue.
-
-2007-01-09 Paolo Bonzini <bonzini@gnu.org>
- and Joel E. Denny <jdenny@ces.clemson.edu>
-
- Simplify union and prologue handling, and escape union and lex/parse
- params with digraphs.
- * data/bison.m4 (b4_pre_prologue, b4_post_prologue): Set their default
- values to the empty string since these are no longer guaranteed
- initialized by the front-end.
- * data/glr.c, data/glr.cc, data/lalr1.cc, data/push.c, data/yacc.c: Add
- braces around b4_user_stype since this is no longer done by the
- front-end.
- * src/files.c, src/files.h (pre_prologue_obstack,
- post_prologue_obstack): Remove.
- * src/muscle_tab.c (muscle_pair_list_grow): Don't duplicate header
- comments here. Use MUSCLE_OBSTACK_SGROW so that values are escaped
- with digraphs. This fixes lex params and parse params.
- * src/muscle_tab.h (muscle_pair_list_grow): Update comments.
- * src/output.c (prepare): Remove muscle insertion of the prologues.
- (output): Remove freeing of pre_prologue_obstack and
- post_prologue_obstack.
- * src/parse-gram.y (prologue_declaration): Use muscle_code_grow rather
- than prologue_augment for prologue parsing so you don't need prologue
- obstacks.
- (grammar_declaration): For %union RHS, use `braceless' instead of
- "{...}" so that braces are already stripped and code is escaped with
- digraphs.
- * src/reader.c (prologue_augment): Remove.
- (reader): Remove initialization of pre_prologue_obstack and
- post_prologue_obstack.
- * src/reader.h (prologue_augment): Remove.
-
- * data/c.m4: Remove stray parenthesis.
-
-2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Remove quotes from variables names in %define directives and from
- qualifiers in %code directives, and restrict the characters that are
- allowed in them to M4-friendly ones. For %define, continue to support
- the quoted form as a deprecated feature. Discussed starting at
- <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00023.html>.
- * NEWS (2.3a+): Add entry for the change to %define. Update entry for
- %code.
- * doc/bison.texinfo (Prologue Alternatives): Update.
- (Decl Summary): In %defines entry, update mention of `%code requires'
- and `%code provides'.
- (C++ Location Values): Update %define uses.
- (Calc++ Parser Interface): Likewise.
- (Calc++ Parser): Likewise, and update `%code requires' uses.
- (Table of Symbols): Update %code documentation.
- * src/parse-gram.y (prologue_declaration): For %define variables, use
- `variable' instead of `STRING'.
- (grammar_declaration): For %code qualifiers, use `ID' instead of
- `STRING'.
- (variable): New nonterminal that takes an `ID' or a `STRING'.
- * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update %code
- and %define uses.

- (%define errors): Update %define uses.
-
-2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * src/parse-gram.y (prologue_declaration): Use MUSCLE_INSERT_STRING
- instead of muscle_insert for %define values so that M4-special
- characters are replaced with digraphs.
- * tests/input.at (%define errors): Extend to check weird values.
-
-2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Instead of having skeletons declare all valid %define variables and
- %code qualifiers, provide macros that retrieve the associated values
- and build these lists automatically. Thus Bison will now warn when a
- variable or qualifier is not used by the skeleton in the current
- invocation regardless of whether it might sometimes be used by that
- skeleton in other invocations. Also, move all %define value macros to
- the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
- form, which is replaced by %code.
- * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
- (b4_check_user_names): ... this, and change the series of valid name
- arguments to a single list argument for names used in the skeleton
- similar to the existing list argument for names used in the grammar.
- Warn instead of complaining.
- (b4_get_percent_define, b4_get_percent_code): New to retrieve %define
- values and %code code, to format %code code properly, and to build
- lists of all %define variables and %code qualifiers used in the
- skeleton: b4_skeleton_percent_define_variables and
- b4_skeleton_percent_code_qualifiers.
- (b4_check_percent_define_variables, b4_check_percent_code_qualifiers):
- Remove, and...
- (m4_wrap): ... m4_wrap b4_check_user_names invocations instead so that
- the skeleton names lists can finish building first. In place of
- b4_used_percent_define_variables and b4_used_percent_code_qualifiers,
- expect the lists b4_user_percent_define_variables and
- b4_user_percent_code_qualifiers.
- * data/c++.m4: Where setting default values for b4_parser_class_name,
- b4_location_type, b4_filename_type, b4_namespace, and
- b4_define_location_comparison, update their names to the
- b4_percent_define_ namespace.
- * data/glr.c: Don't use b4_check_percent_define_variables and
- b4_check_percent_code_qualifiers. Use b4_get_percent_code.
- * data/glr.cc, data/lalr1.cc: Likewise, and use b4_get_percent_define.
- (b4_parser_class_name, b4_namespace): Define these using
- b4_get_percent_define for parser_class_name and namespace.
- * data/location.cc: Use b4_get_percent_define.
- * data/push.c: Don't use b4_check_percent_define_variables and
- b4_check_percent_code_qualifiers. Use b4_get_percent_code.
- * data/yacc.c: Likewise, and don't call m4_exit in
- b4_use_push_for_pull_if or m4_wrap code will never execute.
- * src/muscle_tab.c, src/muscle_tab.h (muscle_grow_used_name_list):
- Rename to...
- (muscle_grow_user_name_list): ... this for consistency with the
- terminology used in bison.m4.
- * src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to
- %define variable names, and rename muscle used_percent_define_variables
- to user_percent_define_variables.
- (grammar_declaration): Rename muscle used_percent_code_qualifiers to
- user_percent_code_qualifiers.
- (content): Remove.
- (content.opt): Replace content RHS with STRING RHS so %define "NAME"
- {CODE} form is no longer accepted.
- * tests/input.at (Reject bad %code qualifiers): Rename to...
- (Reject unused %code qualifiers): ... this, and update test output.
- (%define error): Update test output.
-
-2007-01-07 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Check for unrecognized %define variables similar to checking for
- unrecognized %code qualifiers. Check for redefined %define variables.
- * data/bison.m4 (b4_check_for_unrecognized_names): New macro that
- generalizes...
- (b4_check_percent_code_qualifiers): ... this, which now wraps it.
- (b4_check_percent_define_variables): New, also wraps it.
- * data/glr.c: Unless glr.cc is wrapping glr.c, declare no valid %define
- variables using b4_check_percent_define_variables.
- * data/glr.cc, data/lalr1.cc: Declare the valid %define variables as
- all those exercised in the test suite and all those listed in the
- `Default values' section of c++.m4. Are there others?
- * data/push.c, data/yacc.c: Declare no valid %define variables.
- * src/muscle_tab.c, src/muscle_tab.h (muscle_find_const): New function,
- similar to muscle_find, but it works even when the muscle stores a
- const value.
- (muscle_grow_used_name_list): New function for constructing the used
- name list muscles that b4_check_for_unrecognized_names requires.
- * src/parse-gram.y (prologue_declaration): Warn if a variable is
- %define'd more than once. Define the b4_used_percent_define_variables
- muscle with muscle_grow_used_name_list.
- (grammar_declaration): Abbreviate %code code with
- muscle_grow_used_name_list.
- * tests/input.at (%define errors): New.
-
-2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Provide warn_at, complain_at, and fatal_at function callbacks to the
- skeletons, and use this for %code qualifier complaints.
- * data/bison.m4 (b4_error_at): New, invoked by...
- (b4_warn_at, b4_complain_at, b4_fatal_at): ... these new macros to wrap
- the skeleton scanner's new @warn_at(...@), @complain_at(...@), and
- @fatal_at(...@) directives.
- (b4_check_percent_code_qualifiers): Rewrite to expect locations for
- qualifiers in b4_used_percent_code_qualifiers and to use
- b4_complain_at.

- function.
- * src/muscle_tab.c, src/muscle_tab.h (muscle_boundary_grow): New global

- function.
- (AT_DIRECTIVE_ARGC_MAX): Increase for boundary arguments.
- (lineno): Rename to...
- (out_lineno): ... this so I don't misunderstand it again.
- (SC_AT_DIRECTIVE_SKIP_WS): Don't increment out_lineno for newlines
- here; these newlines are in the input but not the output file.
- (SC_AT_DIRECTIVE_ARG): Likewise. Extract directive execution to...
- (at_directive_perform): ... this new static function, and add handling
- of new @warn_at(...@), @complain_at(...@), and @fatal_at(...@)
- directives.
- * tests/input.at (Reject bad %code qualifiers): Update test output with
- locations and extend.
-
- * tests/output.at (Output file name: [, Output file name: ]): Remove
- bogus comment about these tests failing.
-
-2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Clean up b4_check_percent_code_qualifiers a little.
- * data/bison.m4 (b4_check_percent_code_qualifiers): Expect qualifiers
- in b4_used_percent_code_qualifiers to be double-M4-quoted. Rewrite
- documentation and add examples.
- * src/parse-gram.y (grammar_declaration): Double-M4-quote those
- qualifiers here.
-
-2007-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Don't use m4_divert since it makes m4_divert_push and m4_divert_pop
- unreliable -- especially when they're hidden inside another macro.
- * data/bison.m4, data/c++-skel.m4, data/c++.m4, data/c-skel.m4,
- data/c.m4: Remove m4_divert(-1).
- * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
- data/push.c, data/yacc.c: Likewise, and replace m4_divert(0) with
- m4_divert_push(0) and m4_divert_pop(0).
- * src/output.c (output_skeleton): Don't add an m4_divert_push(0) and
- an m4_wrap([m4_divert_pop(0)]) to the M4. Diversion -1, which is
- pushed and popped by m4sugar, should be first on the stack.
-
- Provide warn, complain, and fatal function callbacks to the skeletons.
- This provides more flexibility than m4_fatal, improves the error
- message format, and captures messages for translation. Discussed
- starting at
- <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00063.html>.
- * data/bison.m4 (b4_error): New, invoked by...
- (b4_warn, b4_complain, b4_fatal): ... these new macros to wrap the
- skeleton scanner's new @warn(...@), @complain(...@), and @fatal(...@)
- directives. Because these M4 macros might be called when the current
- diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus
- the previous removal of uses of m4_divert, which caused trouble.
- (b4_check_percent_code_qualifiers): Use b4_complain instead of
- m4_fatal to report unrecognized %code qualifiers.
- * data/c++-skel.m4: Use b4_complain instead of m4_fatal to report C++
- push parser requests.
- * data/glr.c: Use b4_complain instead of m4_fatal to report
- non-deterministic push parser requests.
- Update @output usage to @output(...@) form.
- * data/glr.cc, data/lalr1.cc: Use b4_fatal instead of m4_fatal to
- report missing %defines. Update @output usage to @output(...@) form.
- * data/location.cc, data/push.c, data/yacc.c: Update @output usage to
- @output(...@) form.
- * src/main.c (main): Invoke skel_scanner_free.
- * src/scan-skel.h (skel_scanner_free): Prototype new function.
- * src/scan-skel.l (FLEX_NO_OBSTACK): Don't define; we now need the
- obstack_for_string from flex-scanner.h.
- (YY_DECL): Use to declare skel_lex static.
- (decode_at_digraphs): Remove; now handled in the new
- SC_AT_DIRECTIVE_ARG start condition.
- (fail_for_at_directive_too_many_args, fail_for_invalid_at): New static
- functions.
- (at_directive_name, AT_DIRECTIVE_ARGC_MAX, at_directive_argc,
- at_directive_argv): New static globals.
- (INITIAL): Use fail_for_invalid_at.
- Don't parse `@output file_name\n' or `@basename(...@)'. Instead,
- recognize the start of a generalized `@directive(...@)' form and
- start...
- (SC_AT_DIRECTIVE_ARG): ... this new start condition to parse the
- directive args (using the new obstack_for_string), to decode the
- contained @ diagraphs, and to perform the directive. It recognizes
- @basename(...@), @warn(...@), @complain(...@), @fatal(...@), and
- @output(...@).
- (SC_AT_DIRECTIVE_SKIP_WS): New start condition started by
- SC_AT_DIRECTIVE_ARG to skip whitespace after the argument delimiter,
- `@,'.
- (scan_skel): Initialize obstack_for_string on the first call.
- (skel_scanner_free): New function to free obstack_for_string.
- * tests/input.at (Reject bad %code qualifiers): Update test output.
-
-2007-01-04 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Consolidate the 4 prologue alternative directives (%code, %requires,
- %provides, and %code-top) into a single %code directive with an
- optional qualifier field. Discussed at
- <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00012.html>.
- * NEWS (2.3a+): Rewrite the existing entry for the prologue
- alternatives.
- * doc/bison.texinfo (Prologue Alternatives): Update.
- (Decl Summary): Update to %code "requires" and %code "provides".
- (Calc++ Parser): Update to %code "requires".
- (Table of Symbols): Remove entries for %requires, %provides, and
- %code-top. Rewrite %code entry, and add a %code "QUALIFIER" entry.
- * data/bison.m4 (b4_user_provides, b4_user_requires): Remove as these
- are replaced by b4_percent_code_provides and b4_percent_code_requires,
- which are skeleton-specific.
- (b4_check_percent_code_qualifiers): New. A skeleton can use this to
- declare what %code qualifiers it supports and to complain if any other
- qualifiers were used in the grammar.
- * data/glr.cc: Update to use b4_user_code([b4_percent_code_requires])
- and b4_user_code([b4_percent_code_provides]) in place of
- b4_user_requires and b4_user_provides.
- * data/glr.c, data/lalr1.cc, data/push.c, data/yacc.c: Likewise.
- Add b4_user_code([b4_percent_code_top]) and
- b4_user_code([b4_percent_code]).
- Invoke b4_check_percent_code_qualifiers.
- * src/parse-gram.y (PERCENT_CODE_TOP, PERCENT_PROVIDES,
- PERCENT_REQUIRES): Remove.
- (grammar_declaration): Remove RHS's for %code-top, %provides, and
- %requires. Rewrite the %code RHS as the unqualified form defining the
- muscle b4_percent_code. Add another RHS for the qualified %code form,
- which defines muscles of the form b4_percent_code_QUALIFIER and the
- b4_used_percent_code_qualifiers muscle.
- * src/scan-gram.l (PERCENT_CODE_TOP, PERCENT_PROVIDES,
- PERCENT_REQUIRES): Remove.
- * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update to use
- %code "requires" and %code "provides".
- * tests/input.at (Reject bad %code qualifiers): New.
-
-2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Use the new code_props interface for destructors and printers.
- * src/symtab.h (symbol, semantic_type): Remove destructor_location and
- printer_location members, and change the type of the destructor and
- printer members to code_props.
- (symbol_destructor_set, symbol_destructor_get, symbol_printer_set,
- symbol_printer_get, semantic_type_destructor_set,
- semantic_type_printer_set, default_tagged_destructor_set,
- default_tagless_destructor_set, default_tagged_printer_set,
- default_tagless_printer_set): Use code_props in arguments and return
- types in place of char const * and location.
- (symbol_destructor_location_get, symbol_printer_location_get): Remove
- since the locations are now contained in the return of
- symbol_destructor_get and symbol_printer_get.
- * src/output.c (symbol_destructors_output, symbol_printers_output):
- Replace with...
- (symbol_code_props_output): ... this to eliminate duplicate code.
- (output_skeleton): Update to use symbol_code_props_output.
- * src/reader.c (symbol_should_be_used): Update use of
- symbol_destructor_get.
- * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):

- * src/symtab.c: (default_tagged_destructor_location,
- default_tagless_destructor_location, default_tagged_printer_location,
- default_tagless_printer_location): Remove since we...
- (default_tagged_destructor, default_tagless_destructor,
- default_tagged_printer, default_tagless_printer): ... change the type
- of these to code_props.
- (symbol_new, semantic_type_new, symbol_destructor_set,
- semantic_type_destructor_set, symbol_destructor_get,
- symbol_printer_set, semantic_type_printer_set, symbol_printer_get,
- symbol_check_alias_consistency, default_tagged_destructor_set,
- default_tagless_destructor_set, default_tagged_printer_set,
- default_tagless_printer_set): Update.
- (symbol_destructor_location_get, symbol_printer_location_get): Remove.
- (SYMBOL_CODE_PRINT): New similar to SYMBOL_ATTR_PRINT but for
- code_props members.
- (symbol_print): Use SYMBOL_CODE_PRINT.
-
-2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Use the new code_props interface for rule actions.
- * src/symlist.h (symbol_list): Replace action, action_location, and
- used members with a code_props action_props member.
- * src/reader.c (symbol_should_be_used, grammar_rule_check,
- grammar_midrule_action, grammar_current_rule_merge_set,
- grammar_current_rule_symbol_append, packgram): Update.
- * src/scan-code.h (translate_rule_action): Remove, no longer used.
- * src/scan-code.l (handle_action_dollar): Update.
- (translate_rule_action): Remove, no longer used.
- * src/symlist.c (symbol_list_sym_new, symbol_list_syms_print): Update.
-
-2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Use the new code_props interface in parse-gram.y.
- * src/parse-gram.y (prologue_declaration, braceless, epilogue.opt):
- Update all uses of translate_* functions to use the new code_props
- interface and to use gram_scanner_last_string_free and
- code_scanner_last_string_free where possible.
- (grammar_declaration): symbol_list_destructor_set and
- symbol_list_printer_set now perform the translation, so don't do it
- here. Use gram_scanner_last_string_free where possible.
- * src/scan-code.h, src/scan-code.l (translate_symbol_action,
- translate_code): Remove, no longer used.
- * src/symlist.h, src/symlist.c (symbol_list_destructor_set,
- symbol_list_printer_set): Perform code translation here rather than
- depending on the caller to do so.
-
- * src/symlist.h (struct symbol_list): Correct some documentation typos.
- * src/scan-gram.h (gram_last_string): Remove declaration.
- * src/scan-gram.l (last_string): Declare it static.
-
-2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Encapsulate code properties and related functionality for the various
- destructors, printers, and actions into a code_props structure and
- interface. This patch merely implements code_props in scan-code.h and
- scan-code.l. Future patches will rewrite other modules to use it.
- Discussed starting at
- <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
- * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
- consistently initialize const structs that have an empty location
- field.
- * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
- to ensure consistency.
- * src/scan-code.h (code_props): New structure.
- (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
- function, macro, and const global variable for initializing a
- code_props with no code.
- (code_props_plain_init, code_props_symbol_action_init,
- code_props_rule_action_init, code_props_translate_code): The rest of
- the new code_props functional interface. Among other things, the init
- functions set the code_props kind field so that
- code_props_translate_code will know whether to behave like
- translate_symbol_action, translate_rule_action, or translate_code.
- These old translate functions must remain until all other modules are
- updated to use the new code_props interface.
- (code_scanner_last_string_free): New function similar to
- gram_scanner_last_string_free.
- (code_scanner_free): Add documentation.
- * src/scan-code.l: Implement the new interface.
- (code_lex): Make it static, add a code_props* argument, and remove the
- rule argument.
- (last_string): New static global similar to the one in scan-gram.l.
- (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
- instead of rule.
- (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
- code_props since Bison may one day use this information for destructors
- and printers.
- (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
- (handle_action_dollar): Use symbol_list_n_get and set used flag
- directly since symbol_list_n_used_set is removed.
- (translate_action): Add a code_props* argument and remove the rule,
- action, and location arguments. Pass the code_props* on to code_lex.
- (translate_rule_action, translate_symbol_action, translate_code):
- Rewrite as wrappers around the new code_props interface.
- * src/symlist.h, src/symlist.c (symbol_list_n_used_set): Remove since
- it would eventually need to break the encapsulation of code_props.
-
-2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * etc/.cvsignore: New.
-
-2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Add maintainer-push-check to run maintainer-check using push parsing in
- place of pull parsing where available.
- * Makefile.am (maintainer-push-check): New.
- * data/bison.m4 (b4_use_push_for_pull_if): New.
- * data/push.c: Redefine b4_push_if and b4_use_push_for_pull_if
- appropriately based on their existing values.
- (yypush_parse): Don't print push-parser-specific diagnostics if push
- parsing is being used in place of pull parsing.
- * data/yacc.c: If push parsing should replace pull parsing, redirect to
- push.c.
- * src/output.c (prepare): Check BISON_USE_PUSH_FOR_PULL environment
- variable, and insert b4_use_push_for_pull_flag into muscles.
- * tests/Makefile.am (maintainer-push-check): New.
-
-2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * data/push.c (yypush_parse): Set yynew = 1 at the end of a parse
- (whether successful or failed) so that yypush_parse can be invoked
- again to start a new parse using the same yypstate.
- * tests/torture.at (AT_DATA_STACK_TORTURE): For push mode, extend to
- check multiple yypull_parse invocations on the same yypstate. For pull
- mode, extend to check multiple yyparse invocations.
- (Exploding the Stack Size with Alloca): Extend to try with
- %push-pull-parser.
- (Exploding the Stack Size with Malloc): Likewise.
-
- * tests/calc.at (Simple LALR Calculator): Don't specify
- %skeleton "push.c" since %push-pull-parser implies that now.
- * tests/headers.at (export YYLTYPE): Don't check for the push
- declarations. Otherwise, this test case can't be used to see if push
- mode can truly emulate pull mode.
- * tests/input.at (Torturing the Scanner): Likewise.
- * tests/local.at (AT_YACC_OR_PUSH_IF, AT_PUSH_IF): Remove.
- (AT_YYERROR_SEES_LOC_IF): Rather than AT_YACC_OR_PUSH_IF, use
- AT_YACC_IF, which now includes the case of push mode since %skeleton
- need not be used for push mode. This will be more intuitive once
- push.c is renamed to yacc.c.
-
-2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
-
- For push mode, convert yyparse from a macro to a function, invoke yylex
- instead of passing a yylexp argument to yypull_parse, and don't
- generate yypull_parse or yyparse unless %push-pull-parser is declared.
- Discussed starting at
- <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00163.html>.
- * data/bison.m4 (b4_pull_if): New.
- * data/c.m4 (b4_identification): Define YYPULL similar to YYPUSH.
- * data/push.c: Improve M4 quoting a little.
- (b4_generate_macro_args, b4_parenthesize): Remove.
- (yyparse): If there's a b4_prefix, #define this to b4_prefix[parse]
- any time a pull parser is requested.
- Don't #define this as a wrapper around yypull_parse. Instead, when
- both push and pull are requested, make it a function that does that
- same thing.
- (yypull_parse): If there's a b4_prefix, #define this to
- b4_prefix[pull_parse] when both push and pull are requested.
- Don't define this as a function unless both push and pull are
- requested.
- Remove the yylexp argument and hard-code yylex invocation instead.
- * etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of
- %push-parser.
- * src/getargs.c (pull_parser): New global initialized to true.
- * getargs.h (pull_parser): extern it.
- * src/output.c (prepare): Insert pull_flag muscle.
- * src/parse-gram.y (PERCENT_PUSH_PULL_PARSER): New token.
- (prologue_declaration): Set both push_parser and pull_parser = true for
- %push-pull-parser. Set push_parser = true and pull_parser = false for
- %push-parser.
- * src/scan-gram.l: Don't accept %push_parser as an alternative to
- %push-parser since there's no backward-compatibility concern here.
- Scan %push-pull-parser.
- * tests/calc.at (Simple LALR(1) Calculator): Use %push-pull-parser
- instead of %push-parser.
- * tests/headers.at (export YYLTYPE): Make yylex static, and don't
- prototype it in the module that calls yyparse.
- * tests/input.at (Torturing the Scanner): Likewise.
- * tests/local.at (AT_PUSH_IF): Check for %push-pull-parser as well.
-
-2006-12-26 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Update etc/bench.pl. Optimize push mode a little (the yyn change
- deserves most of the credit).
- * Makefile.am (SUBDIRS): Add etc subdirectory.
- * configure.ac (AC_CONFIG_FILES): Add etc/bench.pl and etc/Makefile.
- * data/push.c (b4_declare_parser_state_variables): Move yyn, yyresult,
- yytoken, yyval, and yyloc declarations to...
- (yyparse or yypush_parse): ... here to improve performance. For
- yypush_parse invocations after the first, be sure to assign yyn its old
- value again.
- (yypstate_new): Don't bother initializing the yyresult field since the
- initial value isn't used.
- (yyn, yyresult, yytoken, yyval, yyloc): For each NAME in this list,
- remove the #define that, in push mode, set it to yyps->NAME.
- * etc/Makefile.am: New.
- * etc/bench.pl: Remove and build it instead from...
- * etc/bench.pl.in: ... this new file. Use @abs_top_builddir@ to invoke
- "tests/bison" from the build directory by default rather than just
- invoking "bison" from $PATH.
- (calc_grammar): Update push parser code: don't declare yylval globally,
- don't define yyparse_wrapper, and don't #define yyparse.
- (bench_grammar): Update to check all working combinations of yacc.c,
- push.c, impure, pure, pull, and push.
-
-2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
-
- For push mode, add pull wrappers around yypush_parse.
- * data/push.c: (b4_generate_macro_args, b4_parenthesize): New macros.
- (yypull_parse): New function wrapping yypush_parse.
- (yyparse): New #define wrapping yypull_parse.
- * tests/calc.at (_AT_DATA_CALC_Y): Call yyparse even when %push-parser
- is declared.
- * tests/headers.at (export YYLTYPE): Make yylex global. For push mode,
- prototype yylex in the module that calls yyparse, and don't prototype
- yyparse there. Otherwise, the yyparse expansion won't compile.
- * tests/input.at (Torturing the Scanner): Likewise.
-
-2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Enable push parsers to operate in impure mode. Thus, %push-parser no
- longer implies %pure-parser. The point of this change is to move
- towards being able to test the push parser code by running the entire
- test suite as if %push-parser had been declared.
- * data/push.c (yypush_parse): For impure mode, remove the
- yypushed_char, yypushed_val, and yypushed_loc arguments.
- Instead, declare these as local variables initialized to the global
- yychar, yylval, and yylloc.
- For the first yypush_parse invocation only, restore the initial values
- of these global variables when it's time to read a token since they
- have been overwritten.
- * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
- %push-parser.
- * tests/calc.at (Simple LALR(1) Calculator): Always declare
- %pure-parser along with %push-parser since this test case was designed
- for pure push parsers.
- * tests/local.at (AT_PURE_OR_PUSH_IF): Remove unused.
- (AT_YACC_OR_PUSH_IF): New.
- (AT_YYERROR_SEES_LOC_IF): Fix enough that the test suite passes, but
- add a note that it's still wrong for some cases (as it has been for a
- while).
- (AT_PURE_LEX_IF): Use AT_PURE_IF instead of AT_PURE_OR_PUSH_IF since
- %push-parser no longer implies %pure-parser.
-
-2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Remove some unnecessary differences between the pull parser code and
- the push parser code. This patch enables yynerrs in push mode.
- * data/push.c: Reformat M4 a little.
- (b4_yyerror_range): Remove and convert all uses to just yyerror_range.
- (b4_declare_scanner_communication_variables): Don't omit yynerrs just
- because push mode is on. Instead, if pure mode is on, move yynerrs
- to...
- (b4_declare_parser_state_variables): ... here.
- (yynerrs, yyerror_range): For push mode, #define each NAME in this list
- to yyps->NAME so it can be used in yypush_parse.
- (yypush_parse): Don't omit uses of yynerrs in push mode.
-
-2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Fix bug such that the first pushed token's value and location are
- sometimes overwritten (sometimes by %initial-action) before being used.
- * data/push.c (yypush_parse): Rename arguments yynchar, yynlval, and
- yynlloc to yypushed_char, yypushed_val, and yypushed_loc for clarity.
- For the first yypush_parse invocation, initialize yychar to YYEMPTY to
- more closely mimic the pull parser logic.
- Don't copy the pushed token to yychar, yylval, and yylloc until it's
- time to read a token, which is after any initialization of yylval and
- yylloc.
- (gottoken): Rename label to...
- (yyread_pushed_token): ... for clarity and to avoid infringing on the
- user namespace.
-
-2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Rearrange initialization of the parser state variables so that the
- skeleton doesn't have to have a copy for pull mode and another for push
- mode. This patch also fixes at least a bug such that yylloc was not
- initialized (with b4_location_initial_line and
- b4_location_initial_column) upon calling yypush_parse. However, that
- initialization now overwrites the first token's location;
- %initial-action assigning @$ already did the same thing, and both bugs
- will be fixed in a later patch.
- * data/push.c (b4_yyssa): Remove and convert all uses to just yyssa.
- (b4_declare_parser_state_variables): Remove initialization of yytoken,
- yyss, yyvs, yyls, and yystacksize.
- (yypstate_new): Remove initialization of some yypstate fields: yystate,
- yyerrstatus, yytoken, yyss, yyvs, yyls, yystacksize, yyssp, yyvsp, and
- yylsp.
- (yyssa, yyvsa, yylsa): For push mode, #define each NAME in this list to
- yyps->NAME so it can be used in yypush_parse.
- (yyparse or yypush_parse): For yypush_parse, don't print the
- "Starting parse" diagnostic for invocations after the first.
- Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for
- yypush_parse, only do it for the first invocation.
- Allow yystate, yyerrstatus, yyssp, yyvsp, yylsp, and yylloc
- initialization to occur in yypush_parse but only on the first
- invocation.
-
-2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * data/push.c: Add CPP guards around push parser declarations in both
- the header and the code file.
- In the code file, move the push parser declarations to the same place
- they appear in the header file.
- Clean up the M4 some, especially the inconsistent underquoting in
- some b4_c_function_def and b4_c_function_decl uses.
-
-2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Encapsulate the push parser state variables into an M4 macro so the
- push skeleton doesn't have to list them again for pull mode's yyparse.
- For push mode, remove yypush_parse's local equivalents of these
- variables to eliminate unnecessary copying between the two sets at
- run-time. This patch also fixes at least a bug related to multiple
- %initial-action invocations in push mode.
- * data/push.c (b4_declare_parser_variables): Rename to...
- (b4_declare_scanner_communication_variables): ... this for clarity and
- update both uses.
- (b4_declare_yyparse_variables): Remove and move its contents to the one
- spot where it was invoked.
- (b4_declare_parser_state_variables): New macro containing the parser
- state variables required by push mode.
- (struct yypstate): Replace all fields but yynew with
- b4_declare_parser_state_variables.
- (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs,
- yyvsp, yyls, yylsp, yystacksize, yyval, yyloc): For push mode, #define
- each NAME in this list to yyps->NAME so it can be used in yypush_parse.
- (yyparse or yypush_parse): For yyparse in pull mode, replace local
- parser state variable declarations with
- b4_declare_parser_state_variables.
- Don't initialize parser state variables when calling yypush_parse since
- yypstate_new already does that.
- Invoke the user's initial action only upon the first yypush_parse
- invocation.
- Remove all code that copies between the local parser state variables
- and the yypstate.
-
-2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * data/push.c (union yyalloc): Rename yyss, yyvs, and yyls fields to
- prevent a name collision in a future patch where these names will
- sometimes be #define'd.
- (YYSTACK_RELOCATE): Add an argument to select a union yyalloc field
- since it no longer has the same name as the existing argument.
- (yyparse or yypush_parse): Update all uses of YYSTACK_RELOCATE.

- and Joel E. Denny <jdenny@ces.clemson.edu>
-
- * doc/bison.texinfo (Decl Summary): In the %language entry, mention
- that the argument is case-insensitive, and there's no `=' here.
- For the %skeleton entry, mention that %language is better.
- (Bison Options): Likewise for --language and --skeleton. Move the
- --skeleton entry so that the `Tuning the parser' section is sorted
- alphabetically on long options.
- (C++ Bison Interface): Don't use the word skeleton. Don't explain the
- %language directive in detail here; cross-reference the %language
- documentation instead.
- (Calc++ Parser): Use `%require "@value{VERSION}"' rather than
- `%require "2.3b"' so that the example is always up-to-date.
- (Table of Symbols): Add entries for %language and %skeleton.
- * examples/extexi (normalize): Instead of replacing every %require
- argument with the current Bison version, just substitute for
- `@value{VERSION}'. This guarantees that we're testing what actually
- appears in the documentation.
- * examples/calc++/Makefile.am ($(calc_extracted)): Use `$(VERSION)'
- rather than `@VERSION@'.

-2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
-
- * NEWS: Reword the %language news a bit, and put it earlier.
-
- * src/getargs.c (skeleton_arg): Last arg is now location const *.
- Rewrite to simplify the logic.
- (language_argmatch): Likewise.
- (program_name): We now own this var.
- * src/getargs.h (struct bison_language): Use char[] rather than
- const char *.
-
- * doc/bison.texinfo (Decl Summary, Bison Options): Don't claim
- Java is supported.
- * src/complain.c (program_name): Remove decl; no longer needed.
- * src/main.c (program_name): Remove; now belongs to getargs.
-
-2006-12-18 Paolo Bonzini <bonzini@gnu.org>
-
- * NEWS: Document %language.
-

-
-2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
-
- * src/symtab.h (struct semantic_type): Remove the tag 'semantic_type',
- since it wasn't used; only the typedef name 'semantic_type' is needed.
- Also, omit trailing white space.
-
- * bootstrap: Sync from coreutils.
- (gnulib_extra_files): Add build-aux/announce.gen.
- (slurp): Adjust .gitignore files like .cvsignore files.

-
-2006-12-16 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Make %push-parser imply %pure-parser. This fixes several bugs; see
- <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00148.html>.
- * src/parse-gram.y (prologue_declaration): For %push-parser, also set
- pure_parser = true.
- * data/push.c: Don't bother testing b4_push_if when deciding whether
- to expand b4_declare_parser_variables globally.
- (yypush_parse): Likewise in here.
-
- * data/push.c (yypush_parse): Add b4_parse_param to arguments.
- (yy_reduce_print): Reformat M4 for readability.
-
-2006-12-15 Bob Rossi <bob@brasko.net>
- and Joel Denny <jdenny@ces.clemson.edu>
-
- * data/push.c (yypstate): Add typedef, and update all uses of
- struct yypstate to just yypstate.
- * tests/calc.at (_AT_DATA_CALC_Y): Update here as well.
-
-2006-12-14 Bob Rossi <bob@brasko.net>
-
- * data/push.c (yypush_parse): Declare prototype regardless of
- %locations option.
-
-2006-12-14 Bob Rossi <bob@brasko.net>
-
- * data/push.c (yyparse): Remove the prototype and the #define when in
- push-parser mode.
-
-2006-12-13 Bob Rossi <bob@brasko.net>
-
- * data/push.c (yypstate_init): Rename to...
- (yypstate_new): ... this and use b4_c_function_def.
- (yypstate_delete): New.
- (yypush_parse): Change parameters yynval and yynlloc to be const.
- * tests/calc.at (_AT_DATA_CALC_Y): Use new yypstate_new and
- yypstate_delete functions.
-
-2006-12-13 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * configure.ac (AC_PREREQ): Require Autoconf 2.61 because of our
- strange test case titles. Reported by Bob Rossi.
-
-2006-12-13 Paul Eggert <eggert@cs.ucla.edu>
-
- * TODO: Add pointer to Sylvain Schmitz's work on static detection
- of potential ambiguities in GLR grammers.
-
-2006-12-12 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
- `bison ', use m4_index instead of m4_substr since chopping up a string
- containing M4-special characters causes problems here.
-
- Fix a couple of bugs related to special characters in user-specified
- file names, and make it easier for skeletons to compute output file
- names with the same file name prefix as Bison-computed output file
- names.
- * data/glr.cc, data/push.c, data/yacc.c: In @output, use
- b4_parser_file_name and b4_spec_defines_file instead of
- @output_parser_name@ and @output_header_name@, which are now redundant.
- * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
- b4_parser_file_name, b4_spec_defines_file, and the new
- @basename(FILENAME@) instead of @output_parser_name@ and
- @output_header_name@, which inappropriately escaped the file names as
- C string literals.
- * src/files.c (all_but_ext): Remove static qualifier.
- (compute_output_file_names): Move `free (all_but_ext)' to...
- (output_file_names_free): ... here since all_but_ext is needed later.
- * src/files.h (all_but_ext): Extern.
- * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
- exactly what MUSCLE_INSERT_STRING used to do.
- (MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special
- characters are escaped properly.
- * src/output.c (prepare): Define muscle file_name_all_but_ext as
- all_but_ext.
- For pkgdatadir muscle, maintain previous functionality by using
- MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
- is that b4_pkgdatadir is used inside m4_include in the skeletons, so
- digraphs would never be expanded. Hopefully no one has M4-special
- characters in his Bison installation path.
- * src/scan-skel.l: Don't parse @output_header_name@ and
- @output_parser_name@ anymore since they're now redundant.
- In @output, use decode_at_digraphs.
- Parse a new @basename command that invokes last_component.
- (decode_at_digraphs): New.
- (BASE_QPUTS): Remove unused.
- * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): New macro.
- (Output file name): New tests.
-
-2006-12-09 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Warn about output files that are generated by the skeletons and that
- conflict with other output files.
- * data/glr.c: Don't generate the header file here when glr.cc does.
- * src/files.c (file_names, file_names_count): New static globals.
- (compute_output_file_names): Invoke output_file_name_check for files
- not generated by the skeletons and remove existing checks.
- (output_file_name_check): New function that warns about conflicting
- output file names.
- (output_file_names_free): Free file_names.
- * src/files.h (output_file_name_check): Declare.
- * src/scan-skel.l: Invoke output_file_name_check for files generated by
- the skeletons.
- * tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): New.
- (Conflicting output files): New tests.
-
-2006-12-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
-
- * doc/bison.texinfo: Fix a couple of typos.
-
-2006-12-08 Bob Rossi <bob@brasko.net>
-
- * data/push.c: (yypvarsinit, yypvars, struct yypvars, yypushparse):
- Rename to...
- (yypstate_init, yypstate, struct yypstate, yypush_parse): ... these and
- update all uses.
- (b4_yyssa, b4_yyerror_range, yypstate_init): Rename pv to yyps.
- (yypush_parse): Rename yypvars argument to yyps and remove redundant
- local pv.
- (yypstate_init, yypush_parse): Declare in Bison-generated header file.
- * tests/calc.at (_AT_DATA_CALC_Y): Use newly named functions.
-
-2006-12-07 Bob Rossi <bob@brasko.net>
- and Joel Denny <jdenny@ces.clemson.edu>
-
- * data/push.c (yypvarsinit): Change return type from void* to struct
- yypvars*. No longer cast to void* on return.
- (struct yypvars): Remove yylen since it need not be remembered between
- yypushparse invocations.
- (yypushparse): Don't copy between yylen and pv->yylen.
-
-2006-12-05 Bob Rossi <bob@brasko.net>
-
- * data/push.c (yychar_set, yylval_set, yylloc_set): Delete.
- (yypushparse): Add yynchar, yynlval, yynlloc parameters.
- (b4_declare_parser_variables): Do not declare yynerrs for push mode.
- (struct yypvars): Remove b4_declare_parser_variables.
- (yypvarsinit): Remove init code for removed variables.
- (global scope): Do not declare b4_declare_parser_variables if
- push or pure mode.
- (yypushparse): Add b4_declare_parser_variables.
- Init new local variables, and remove init code for removed
- yypvars variables.
- (yyparse): Delete.
- * tests/calc.at (_AT_DATA_CALC_Y): Call yypushparse for push mode
- and yyparse for other modes.
- (AT_CHECK_CALC_LALR): Added '%skeleton "push.c"' for push tests.
- * tests/local.at (AT_PUSH_IF, AT_PURE_OR_PUSH_IF): Added.
- (AT_YYERROR_SEES_LOC_IF): push-parser makes this false.
- (AT_PURE_LEX_IF): True if pure or push parser.

-
- Document Yacc prologue alternatives and default %destructor's and
- %printer's as experimental. Don't mention Java yet. Discussed at

-2006-12-01 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Support a file name argument to %defines. Deprecate `=' in

- it was double-quoted.
- * src/Makefile.am (YACC): Use --warnings=all,error so that Bison's own
- grammar is maintained with Bison's highest standards.
- * src/getargs.c: Fix some typos in Doxygen comments.
-
-2006-11-10 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Fix memory leaks in scanners generated by at least Flex 2.5.9 and
- later. Reported by Paul Eggert in
- <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00014.html>.
- * src/flex-scanner.h (yylex_destroy): Define for Flex before 2.5.9.
- * src/scan-code.l (translate_action): Don't bother invoking
- yy_delete_buffer (YY_CURRENT_BUFFER) before creating the first buffer.
- (code_scanner_free): Instead of invoking
- yy_delete_buffer (YY_CURRENT_BUFFER) directly, invoke yylex_destroy,
- which frees more.
- * src/scan-gram.l (gram_scanner_free): Likewise.
- * src/scan-skel.l (scan_skel): Likewise.
-
-2006-11-09 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * src/files.c (tr): Change return type to void.
- * src/muscle_tab.c (muscle_insert): Free storage in case muscle_grow
- has been called previously for the same key.
- (muscle_find): Return storage instead of value so that
- --enable-gcc-warnings doesn't produce warnings that the return discards
- const. aver that the value and storage are the same since storage
- could potentially be NULL when value is not.
- * tests/testsuite.at (AT_CHECK): Treat an unspecified exit value the
- same as 0.
-
-2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
-
- * bootstrap.conf (excluded_files): Exclude m4/codeset.m4 (undoing
- the earlier change today), m4/intl.m4, m4/intldir.m4. This gives
- us a slightly cleaner distribution, and also works.
- * m4/.cvsignore: Add inline.m4, wint_t.m4 to accommodate recent
- gnulib changes.
-
-2006-11-08 Joel E. Denny <jdenny@ces.clemson.edu>

-
- Don't let Bison leak memory except when it complains.

- since they are freed.
- * src/files.c: Likewise.
- (all_but_ext, all_but_tab_ext, src_extension, header_extension):
- Likewise.
- (tr): Now operates in-place. All uses changed.
- (compute_exts_from_gf, compute_exts_from_src): Don't leak temporary
- values.
- (compute_file_name_parts, compute_output_file_names): Don't store

- will be freed.
- * src/main.c (main): Invoke output_file_names_free, code_scanner_free
- (which previously existed but was unused), and quotearg_free.
- * src/muscle_tab.h (muscle_insert): value arg is now a `char const *'.

- and add a new storage member that is char * and can be freed.
- (muscle_entry_free): New private function.

- (translate_symbol_action, translate_code, translate_action): Return
- `char const *' rather than `char *' since external code should not free
- these strings.
- * src/scan-code.l: Likewise.
- * src/scan-gram.l (<SC_BRACED_CODE>): Use val->code for BRACED_CODE,
- which is "{...}" in the parser.
- * tests/Makefile.am (maintainer-check-valgrind): Set
- VALGRIND_OPTS='--leak-check=full --show-reacheable=yes' before invoking
- Valgrind.
- * tests/calc.at (_AT_DATA_CALC_Y): fclose the FILE* so Valgrind doesn't
- complain.
- * tests/testsuite.at (AT_CHECK): Redefine so that running Bison and
- expecting a non-zero exit status sets --leak-check=summary and
- --show-reachable=no for Valgrind. Bison unabashedly leaks memory in
- this case, and we don't want to hear about it.
-
-2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
-
- * bootstrap (runtime-po/Makevars): Derive from po/Makevars
- instead of from the template, to simplify configuration a bit.
- * bootstrap.conf (excluded_files): Don't exclude m4/codeset.m4

- * tests/input.at (Unused values, Unused values before symbol
- declarations): Run tests with and without --warnings=midrule-values.
-
- * src/reader.c (check_and_convert_grammar): Use symbol_list_free rather

-
-2006-10-31 Joel E. Denny <jdenny@ces.clemson.edu>

- * src/getargs.h (enum warnings): Unset warnings_error in warnings_all.
-
-2006-10-31 Joel E. Denny <jdenny@ces.clemson.edu>

- <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00104.html>.
- * src/symtab.c (dummy_symbol_get): Name all dummy symbols initially
- like $@n instead of just @n so that the default %destructor/%printer
- logic doesn't see them as user-defined symbols.
- (symbol_is_dummy): Check for both forms of the name.
- * src/reader.c (packgram): Remove the `$' from each midrule symbol
- name for which the midrule value is referenced in any action.
- * tests/actions.at (Default %printer and %destructor for mid-rule
- values): New test.

- for change to dummy symbol names.
-
-2006-10-20 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Warn about unset midrule $$ if the corresponding $n is used.
- * src/reader.c (symbol_should_be_used): Check midrule parent rule for
- $n usage.
- (packgram): Before invoking grammar_rule_check on any rule, make sure
- all actions have already been scanned in order to set `used' flags.
- Otherwise, checking that a midrule's $$ is set will not always work
- properly because the midrule check must forward-reference the midrule's
- parent rule.
- * tests/input.at (AT_CHECK_UNUSED_VALUES): Extend to check the new
- warning.
-
-2006-10-20 Joel E. Denny <jdenny@ces.clemson.edu>

- to show how these directives may be viewed as code labels.
-
-2006-10-16 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Similar to the recently removed %before-header, add %code-top as the
- alternative to the pre-prologue. Mentioned at
- <http://lists.gnu.org/archive/html/bison-patches/2006-10/msg00063.html>.
- Also, let the prologue alternatives appear in the grammar section.
- * src/parse-gram.y (PERCENT_CODE_TOP): New token.
- (prologue_declaration): Move the existing prologue alternatives to...
- (grammar_declaration): ... here and add %code-top.

-
- Clean up and extend documentation for the prologue alternatives.
- * NEWS (2.3a+): Describe prologue alternatives.

- sticks with the automake default in generating dependencies.
-
-2006-10-12 Paul Eggert <eggert@cs.ucla.edu>

- (gnulib_files): Add support for this variable (used by Bison).
-
-2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
-
- * src/getargs.c (usage): Rework to use conventions similar to

- (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us.
- * src/system.h: Include inttypes.h unconditionally, now that we

- * src/main.c: Likewise.
- * src/output.c: Likewise.

-
- * src/parse-gram.y (symbol_declaration): Don't put statements
- before declarations; it's not portable to C89.
- * src/scan-code.l (handle_action_at): Likewise.
-
- * src/scan-code.l: Always initialize braces_level; the old code
- left it uninitialized and therefore had undefined behavior.
-
- Don't attempt to redefine 'assert', since it runs afoul of
- systems where standard headers (mistakenly) include <assert.h>.
- Instead, define and use our own alternative, called 'aver'.
- * src/reader.c: Don't include assert.h, since we no longer
- use assert.
- * src/scan-code.l: Likewise.
- * src/system.h (assert): Remove, replacing with....

-
- * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove

- runtime cost when YYDEBUG is not defined, and so that some tests
- that used to fail now work. Problem and initial suggestion by
- Paolo Bonzini.
- * data/c++.m4 (b4_parse_param_cons): Omit leading ','.
- * data/glr.cc (b4_parser_class_name):

- AT_CHECK_CALC_GLR_CC that are working now.
-
-2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
-
- * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove.
- We don't need them in glr.cc, and glr.c defines them.
- Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c
- assumes that defining it to anything is the same as defining
- it to 1. Problem reported by Paolo Bonzini.
-
-2006-09-12 Paolo Bonzini <bonzini@gnu.org> (tiny change)
-
- * data/c.m4 (b4_null, b4_case): Define.

- before any #includes that we generate, so that feature-test
- macros work. Problem reported by Michael Deutschmann in
- <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00004.html>.
- * data/lalr1.cc: Likewise.
- * doc/bison.texinfo (Prologue): Document that feature-test macros
- should be defined before any Bison declarations.
- * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns
- that depend on location.hh after, not before, Bison decls, since
- we now include location.hh after the first user prologue.
-
- * doc/bison.texinfo (Calc++ Parser): Fix memory leak reported by
- Sander Brandenburg in
- <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00002.html>.
- Also, fix minor white space and comment issues.

- before Bison declarations. Problem reported by Michael Deutschmann.
-
- * README-cvs: Fix typo: "&" should be "&&". Problem reported

- composing the public interface of that table.
- (symbol_destructor_get, symbol_destructor_location_get,
- symbol_printer_get, symbol_printer_location_get): If there's no

- * tests/actions.at (Per-type %printer and %destructor): New test case.
- * tests/input.at (Default %printer and %destructor redeclared):
- Extend to check that multiple occurrences of %symbol-default in a

- per-type %destructor): New test cases.
-
-2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>

- (grammar_declaration): Use generic_symlist in %destructor and %printer
- declarations instead of symbols.1 or an empty list.
- (symbol_declaration, precedence_declaration, symbols.1): Update actions
- for changes to symbol_list.
- * src/reader.c: Update for changes to symbol_list.
- * src/scan-code.l: Likewise.
- * src/scan-gram.l: Scan new PERCENT_SYMBOL_DEFAULT token.
- * src/symlist.c, src/symlist.h: Extend such that a list node may
- represent a semantic type or a %symbol-default in addition to just an
- ordinary symbol. Add switched functions for setting %destructor's and
- %printer's.
- * tests/actions.at, tests/input.at: Add %symbol-default to all default
- %destructor/%printer declarations.
-
-2006-08-23 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Whether the default %destructor/%printer applies to a particular symbol
- isn't a question of whether the user *declares* that symbol (in %token,
- for example). It's a question of whether the user by any means
- *defines* the symbol at all (by simply using a char token, for
- example). $end is defined by Bison whereas any other token with token
- number 0 is defined by the user. The error token is always defined by
- Bison regardless of whether the user declares it with %token, but we
- may one day let the user define error as a nonterminal instead.
- * NEWS (2.3+): Say "user-defined" instead of "user-declared".
- * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
- the meaning of "user-defined".
- * tests/actions.at (Default %printer and %destructor for user-declared
- end token): Rename to...
- (Default %printer and %destructor for user-defined end token): ...
- this.
-
- * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
- computation of whether to apply the default, don't maintain a list of
- every Bison-defined symbol. Instead, just check for a first character
- of '$', which a user symbol cannot have, and check for the error token.
-
-2006-08-21 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Don't apply the default %destructor or %printer to the error token,
- $undefined, or $accept. This change fits the general rule that the
- default %destructor and %printer are only for user-declared symbols,
- and it solves several difficulties that are described in the new test
- cases listed below.
- * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement.
- * tests/actions.at (Default %printer and %destructor are not for error
- or $undefined, Default %printer and %destructor are not for $accept):
- New test cases.
-
-2006-08-19 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Allow %start after the first rule.
- * src/reader.c (grammar_current_rule_begin): Don't set the start symbol
- when parsing the first rule.
- (check_and_convert_grammar): Search for it here after all grammar
- declarations have been parsed. Skip midrules, which have dummy LHS
- nonterminals.
- * src/symtab.c (symbol_is_dummy): New function.
- * src/symtab.h (symbol_is_dummy): Declare it.
- * tests/input.at (%start after first rule): New test.
-
-2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Redo some of the previous commit: add back the ability to use
- non-aliased/undeclared string literals since it might be useful to
- those declaring %token-table.
- * src/reader.c (check_and_convert_grammar): Undo changes in previous
- commit: don't worry about complaints from symbols_pack.
- * src/symtab.c (symbol_new, symbol_class_set,
- symbol_check_alias_consistency): Undo changes in previous commit: count
- each string literal as a new symbol and token, assign it a symbol
- number, and don't complain about non-aliased string literals.
- (symbols_pack): Since symbol_make_alias still does not decrement symbol
- and token counts but does still set aliased tokens to the same number,
- symbol_pack_processor now leaves empty slots in the symbols array.
- Remove those slots.
- * tests/regression.at (Undeclared string literal): Remove test case
- added in previous commit since non-aliased string literals are allowed
- again.
- (Characters Escapes, Web2c Actions): Undo changes in previous commit:
- remove unnecessary string literal declarations.
- * tests/sets.at (Firsts): Likewise.
-
-2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Don't allow an undeclared string literal, but allow a string literal to
- be used before its declaration.
- * src/reader.c (check_and_convert_grammar): Don't invoke packgram if
- symbols_pack complained.
- * src/symtab.c (symbol_new): Don't count a string literal as a new
- symbol.
- (symbol_class_set): Don't count a string literal as a new token, and
- don't assign it a symbol number since symbol_make_alias does that.
- (symbol_make_alias): It's not necessary to decrement the symbol and
- token counts anymore. Don't assume that an alias declaration occurs
- before any uses of the identifier or string, and thus don't assert that
- one of them has the highest symbol number so far.
- (symbol_check_alias_consistency): Complain if there's a string literal
- that wasn't declared as an alias.
- (symbols_pack): Bail if symbol_check_alias_consistency failed since
- symbol_pack asserts that every token has been assigned a symbol number
- although undeclared string literals have not.
- * tests/regression.at (String alias declared after use, Undeclared
- string literal): New test cases.
- (Characters Escapes, Web2c Actions): Declare string literals as
- aliases.
- * tests/sets.at (Firsts): Likewise.
-
-2006-08-14 Joel E. Denny <jdenny@ces.clemson.edu>
-
- In the grammar scanner, STRING_FINISH unclosed constructs and return
- them to the parser in order to improve error messages.
- * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER,
- SC_BRACED_CODE, SC_PROLOGUE): Implement.
- * tests/input.at (Unclosed constructs): New test case.
- * tests/regression.at (Invalid inputs): Update now that unclosed %{ is
- seen.
-
- * src/scan-gram.h, src/scan-gram.l (gram_last_braced_code_loc): Remove
- unused global.
-
-2006-08-13 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Handle string aliases for character tokens correctly.
- * src/symtab.c (symbol_user_token_number_set): If the token has an
- alias, check and set its alias's user token number instead of its own,
- which is set to indicate the alias. Previously, every occurrence of
- the character token in the grammar overwrote that alias indicator with
- the character code.
- * tests/input.at (String aliases for character tokens): New test.
-
-2006-08-12 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * src/parse-gram.y: Add `%expect 0' so we don't overlook conflicts.
-
-2006-08-11 Paul Eggert <eggert@cs.ucla.edu>
-
- * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT,
- to prevent failures when building on older platforms.
- Check for autopoint failure.
- Set XGETTEXT_OPTIONS to values that check for C format strings,
- so that translators are warned about them (this also helps
- prevent core dumps).
-
- * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer
- function, since it simplifies our code a bit.
-
- * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare
- rather than -W, so we don't get bogus warnings about sign comparisons.
- Add -Wpointer-arith, since that warning is useful (it reports code
- that does not conform to C89 and that some compilers reject).
- * data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change,
- since it's no longer needed.
-
-2006-08-10 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Clean up scanners a bit.
- * src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack
- definitions so gcc won't warn when obstack_for_string is unused.
- * src/scan-code.l: config.h and system.h are already #include'd by
- scan-code-c.c, so get rid of them here.
- * src/scan-gram.l: Likewise.
- * src/scan-skel.l: Likewise, and use flex-scanner.h without obstack
- definitions rather than duplicating the rest of it.
- * src/scan-gram-c.c, scan-skel-c.c: #include "system.h".
-
-2006-08-09 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Suppress signed/unsigned comparison warnings for yycheck.
- * data/c.m4 (b4_safest_int_type): New macro.
- * data/glr.c, data/lalr1.cc: Wherever you compare yycheck[i] against
- a signed int type, cast it to b4_safest_int_type first.
- * data/yacc.c: Likewise.
- (b4_safest_int_type): Overwrite the one from c.m4 since b4_int_type is
- also overwritten.
-
-2006-08-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
-
- * doc/bison.texinfo: Fix some typos.
-
-2006-08-02 Paul Eggert <eggert@cs.ucla.edu>
-
- * m4/.cvsignore: Add inttypes_h.m4,lib-ld.m4, lib-prefix.m4,
- po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4.
-
- * bootstrap (gnulib_tool): Stop using --assume-autoconf;
- the latest gnulib does this a different way.
- (get_translations): Sharuzzaman Ahmat Raslan reported that the ms
- translation was patched, so stop omitting it.
-
-2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Enable declaration of default %printer/%destructor. Make the parser
- use these for all user-declared grammar symbols for which the user does
- not declare a specific %printer/%destructor. Thus, the parser uses it
- for token 0 if the user declares it but not if Bison generates it as
- $end. Discussed starting at
- <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>,
- <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>,
- and
- <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>.
- * NEWS (2.3+): Mention.
- * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
- declare a %destructor for a mid-rule's semantic value. It's just
- impossible to declare one specific to it.
- (Freeing Discarded Symbols): Mention that @$ can be used in %destructor
- code. Describe default %destructor form.
- * src/parse-gram.y (grammar_declaration): Parse default
- %printer/%destructor declarations.
- * src/output.c (symbol_destructors_output): Use symbol_destructor_get
- and symbol_destructor_location_get rather than accessing the destructor
- and destructor_location members of struct symbol.
- (symbol_printers_output): Likewise but for %printer's.
- * src/reader.c (symbol_should_be_used): Likewise but for %destructor's
- again.
- * src/symtab.c (default_destructor, default_destructor_location,
- default_printer, default_printer_location): New static global
- variables to record the default %destructor and %printer.
- (symbol_destructor_get, symbol_destructor_location_get,
- symbol_printer_get, symbol_printer_location_get): New functions to
- compute the appropriate %destructor and %printer for a symbol.
- (default_destructor_set, default_printer_set): New functions to set the
- default %destructor and %printer.
- * src/symtab.h: Prototype all those new functions.
- * tests/actions.at (Default %printer and %destructor): New test to
- check that the right %printer and %destructor are called, that they're
- not called for $end, and that $$ and @$ work correctly.
- (Default %printer and %destructor for user-declared end token): New
- test to check that the default %printer and %destructor are called for
- a user-declared end token.
- * tests/input.at (Default %printer and %destructor redeclared, Unused
- values with default %destructor): New tests to check related grammar
- warnings and errors.
-
-2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Clean up handling of %destructor for the end token (token 0).
- Discussed starting at
- <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>
- and
- <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>.
-
- Make the skeletons consistent in how they pop the end token and invoke
- its %destructor.
- * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
- state, which has token number 0, since this would invoke the
- %destructor for the end token.
- * data/lalr1.cc (yy::parser::parse): Don't check for the final state
- until after shifting the end token, or else it won't be popped.
- * data/yacc.c (yyparse): Likewise.
-
- * data/glr.c (yyparse): Clear the lookahead after shifting it even when
- it's the end token. Upon termination, destroy an unshifted lookahead
- even when it's the end token.
- * data/lalr1.cc (yy::parser::parse): Likewise.
- * data/yacc.c (yyparse): Likewise.
-
- * src/reader.c (packgram): Don't check rule 0. This suppresses unused
- value warnings for the end token when the user gives the end token a
- %destructor.
-
- * tests/actions.at (Printers and Destructors): Test all the above.
-
-2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
-
- Update to latest gnulib and gettext versions.
- * bootstrap (gnulib-modules): Remove hard-locale, stdio-safer.
- Add fopen-safer.
- (gnulib_files): Add m4/warning.m4. Don't worry about files
- overwritten by autopoint.
- Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
- Suppress "id", "ms", "tr" translations for now, since gettext 0.15
- rejects them.
- Don't use autoreconf; instead, invoke autopoint etc. by hand,
- so that we can remove the intl files at a better time.
- (intl_files_to_remove): Remove aclocal.m4, since it gets
- rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
- m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,
- m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4.
- Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4.
- Remove datarootdir hack; no longer needed.
- * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
- (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
- * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
- strdup.h.
- * m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
- * m4/warning.m4: Remove from CVS, since we now use gnulib's version.
-
-2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
-
- * bootstrap: Adjust to today's change to gnulib-tool by invoking
- it with --assume-autoconf='latest-stable'.
-
-2006-07-13 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * src/parse-gram.y (grammar_declaration): Don't confuse Doxygen (at
- least 1.4.7 and 1.4.4) by putting a #line between `typedef union
- YYSTYPE' and `{'.
- * src/muscle_tab.h (muscle_grow): Replace the header comments with
- those from muscle_tab.c since the old ones are misleading.
-
-2006-07-13 Akim Demaille <akim@epita.fr>
-
- Support %define "KEY" {VALUE}.
- * src/scan-code.h, src/scan-code.l (translate_action)
- (translate_rule_action, translate_symbol_action, translate_code):
- Return char *, not const char *.
- * src/parse-gram.y (declaration): Rename as...
- (prologue_declaration): this.
- (string_content): Remove this nonterminal, use STRING.
- (braceless, content, content.opt): New nonterminal.
- Use them.
- (%define): Now accept content.opt, i.e., accept also BRACED_CODE
- as value.
- * src/scan-gram.l (getargs.h): Don't include it.
-
-2006-07-12 Paul Eggert <eggert@cs.ucla.edu>
-
- * data/lalr1.cc (YYCDEBUG): Use 'if (yydebug_) (*yycdebug_)'
- rather than a for-loop that declares a local bool variable. This
- should work around a compatibility problem with a Cray x1e C++
- compiler reported by Hung Nguyen in
- <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00022.html>.
- The for-loop was introduced in the 2004-11-17 change but I don't
- know why it was needed.
-
-2006-07-12 Akim Demaille <akim@epita.fr>
-
- * data/c.m4: Comment changes.
-
-2006-07-10 Akim Demaille <akim@lrde.epita.fr>
-
- * src/complain.c (error_message, ERROR_MESSAGE): New.
- To factor...
- (fatal_at, fatal, warn_at, warn, complain_at, complain): these.
- * src/complain.h, src/complain.c (warning_issued): Remove, unused.
-
-2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
-
- * NEWS: Instead of %union, you can define and use your own union type
- YYSTYPE if your grammar contains at least one <type> tag.
- Your YYSTYPE need not be a macro; it can be a typedef.
- * doc/bison.texinfo (Value Type, Multiple Types, Location Type):
- (Union Decl, Decl Summary): Document this.
- * data/glr.c (YYSTYPE): Implement this.
- * data/glr.cc (YYSTYPE): Likewise.
- * data/lalr1.cc (YYSTYPE): Likewise.
- * data/yacc.c (YYSTYPE): Likewise.
- * src/output.c (prepare): Output tag_seen_flag.
- * src/parse-gram.y (declaration, grammar_declaration):
- Use 'union_seen' rather than 'typed' to determine whether
- %union has been seen, since grammars can now be typed without
- %union.
- (symbol_declaration, type.opt, symbol_def):
- Keep track of whether a tag has been seen.
- * src/reader.c (union_seen, tag_seen): New vars.
- (typed): remove.
- * src/reader.h (union_seen, tag_seen, typed): Likewise.
- * src/scan-code.l (untyped_var_seen): New variable.
- (handle_action_dollar): Adjust to above changes.
- (handle_action_dollar, handle_action_at):
- Improve overflow checking for outlandish numbers.
- * tests/input.at (AT_CHECK_UNUSED_VALUES): Redo test to
- avoid new diagnostics generated by above changes.
- * tests/regression.at (YYSTYPE typedef): Add test to check
- for type tags without %union.
-
- * src/symlist.c (symbol_list_length): Return int, not unsigned
- int, since callers expect int. This may need to get revisited
- once we have proper integer overflow checking.
-
- * src/scan-gram.h (gram_scanner_cursor): Remove decl, since this
- object is now static.
-
- * src/getargs.c (flags_argmatch): Return void, not int,
- to pacify ./configure --enable-gcc-warnings.
-
- * src/flex-scanner.h (STRING_FREE): Don't use FLEX_PREFIX (last_string)
- since last_string is already defined to FLEX_PREFIX (last_string).
-
-2006-07-09 Akim Demaille <akim@lrde.epita.fr>
-
- Implement --warnings/-W.
- * src/getargs.c (report_argmatch, trace_argmatch): Remove,
- replaced by...
- (flags_argmatch, FLAGS_ARGMATCH): this new function and macro.
- Adjust callers.
- * src/getargs.h, src/getargs.c (warnings, warnings_flags)
- (warnings_args, warnings_types): New.
- (getargs, short_options, long_options): Accept -W/--warnings.
- Sort the options by alphabetical order, upper case letter right
- before its lower case.
-
-2006-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Change %merge result type clash warnings to errors. Discussed at
- <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00026.html>.
- * src/reader.c (record_merge_function_type): Use complain_at.
- * tests/glr-regression.at (Missed %merge type warnings when LHS type is
- declared later): Update test case results.
-
-2006-07-09 Akim Demaille <akim@lrde.epita.fr>
-
- * src/getargs.h, src/getargs.c: Swap --report and --trace handling
- to be in alphabetical order.
- (trace_args): Spelling fixes.
-
-2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
-
- * data/yacc.c (YYID, yy_stack_print): Prefix local vars with "yy"
- so they don't collide with user-defined macros.
- (yy_stack_print): Don't assume that yytype_int16 promotes to int;
- this was never guaranteed, and now that we're using gnulib stdint,
- which defines int_fast16_t to long int, the problem is exposed.
-
-2006-07-08 Paul Eggert <eggert@cs.ucla.edu>
-
- * data/c.m4 (b4_basename): Simplify a bit, since we don't
- need the full POSIX semantics (and weren't implementing them
- anyway).
-
- Adjust to Autoconf 2.60 and today's gnulib.
- * bootstrap (gnulib_modules): Add stdint.
- Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
- no longer copies it.
- (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
- since stdint needs the former and wcwidth (which is now required
- by mbswidth) needs the latter.
- Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
- work around a compatibility glitch between gettext 0.14.6 and
- Autoconf 2.60.
- * configure.ac (AC_PREREQ): Require Autoconf 2.60.
- Do not check for uintptr_t, since new stdint module does the right
- thing.
- * lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h.
- Add stdint.h, stdint_.h, wcwidth.h.
- * m4/.cvsignore: Remove alloca.m4, onceonly.m4.
- Add absolute-header.m4, double-slash-root.m4, longlong.m4,
- stdint.m4, wchar_t.m4, wcwidth.m4.
- * src/files.c: Include <dirname.h> and <stdio-safer.h> in the
- usual order for ../lib/*.h files.
- (file_name_split): Use last_component, not base_name, to adjust
- to gnulib changes.
- * src/parse-gram.h: Include <strverscmp.h> in the usual order
- for ../lib/*.h files.
- (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
- Define unconditionally, since we now assume the stdint module.
- * src/scan-skel.l: Include <dirname.h>.
- (BASE_QPUTS): Use last_component, not base_name.
- * src/system.h: Include <unlocked-io.h> in the usual order
- for ../lib/*.h files. Include <stdint.h> unconditionally,
- since we now use the stdint module.
- (uintptr_t): Declare if UINTPTR_MAX is not defined, not
- HAVE_UINTPTR_T, since we now use the stdint module.
- (base_name): Remove decl, since files now include <dirname.h>
- to get the decl.
-
-2006-07-08 Akim Demaille <akim@lrde.epita.fr>
-
- * data/c.m4 (b4_location_initial_column, b4_location_initial_line):
- New, default to 1.
- * data/yacc.c, data/glr.c, data/location.cc: Use them.
- * NEWS, doc/bison.texinfo: The initial column and line are 1 by
- default.
- * tests/calc.at: Adjust.
-
-2006-07-08 Akim Demaille <akim@lrde.epita.fr>

-
-2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
-
- In the grammar file, the first column is 1 not 0 on the first line as
- on every other line.
- * src/parse-gram.y (%initial-action): Initialize @$ correctly.
- * tests/input.at (Torturing the Scanner): Update output.
-
- * src/scan-gram.l (scanner_cursor): Declare it static.
-
-2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
-
- In warnings, say "previous declaration" rather than "first
- declaration".
- * src/symtab.c (redeclaration): Do that here.
- * src/reader.c (record_merge_function_type): In the case of a result
- type clash, report the previous declaration rather than the very first
- one in the grammar file.
- * tests/glr-regression.at (Missed %merge type warnings when LHS type is
- declared later): Add a third declaration to check this behavior.
- * tests/input.at (Incompatible Aliases): Update output.
-
-2006-06-27 Akim Demaille <akim@epita.fr>
-
- * doc/Doxyfile.in: New.

- * src/lalr.h, src/symtab.h: Initial doxygenation.
-
-2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>

- Don't miss %merge result type warnings just because the LHS types are
- declared after the %merge. This continues the effort of the previous
- patch.
- * src/reader.c (get_merge_function): Don't set the merger type yet.
- (record_merge_function_type): New function for setting the merger type
- and checking for clashes.
- (grammar_current_rule_merge_set): Set the location of the %merge for
- the current rule.
- (packgram): Invoke record_merge_function_type for each rule now that
- all symbol type declarations have been parsed.
- * src/reader.h (merger_list.type_declaration_location): New member
- storing the location of the first %merge from which the type for this
- merging function was derived.
- * src/symlist.h (symbol_list.merger_declaration_location): New member

- Get action warnings (grammar_rule_check) right even when symbol
- declarations appear after the rules. Discussed at
- <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00108.html>
- and
- <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00151.html>.
- Don't mistake the type of $$ in a midrule to be that of its parent
- rule's $$.
- * src/reader.c (grammar_current_rule_end): Don't invoke
- grammar_rule_check yet since not all symbol declarations may have been
- parsed yet.
- (grammar_midrule_action): Likewise.
- Don't record whether the midrule's $$ has been used yet since actions
- haven't been translated yet.
- Record the midrule's parent rule and its RHS index within the parent
- rule.
- (grammar_current_rule_action_append): Don't translate the action yet
- since not all symbol declarations may have been parsed yet and, thus,
- warnings about types for $$, $n, @$, and @n can't be reported yet.
- (packgram): Translate the action and invoke grammar_rule_check now that
- all symbol declarations have been parsed.
- * src/scan-code.l (handle_action_dollar): Now that this is invoked
- after parsing the entire grammar file, the symbol list here in the case
- of a midrule is actually the midrule's empty RHS, so reference its
- parent rule's RHS where necessary.
- On the other hand, now that you can already know it's a midrule, you
- aren't forced to think $$ has the same type as its parent rule's $$.
- (handle_action_at): In the case of a midrule, reference the parent rule
- where necessary.
- * src/symlist.c (symbol_list_new): Initialize new midrule-related
- members.
- (symbol_list_length): Now that this is invoked after all rules have
- been parsed, a NULL symbol (rather than a NULL symbol list node)
- terminates a rule. symbol_list_print already does this correctly.
- * src/symlist.h (symbol_list.midrule_parent_rule,
- symbol_list.midrule_parent_rhs_index): New members so that midrules can
- remember their relationships with their parents.
- * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
- fixed by the above patch.
- (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros
- implementing...
- (Unused values): ... this old test case and...
- (Unused values before symbol declarations): ... this new test case.
- This one is the same as `Unused values' except that all symbol
- declarations appear after the rules in order to catch the rest of the
- errors fixed by the above patch.
-
-2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
-
- More cleanup.

- * src/reader.h (current_rule): Remove this unused extern.
- * src/scan-code.h (translate_rule_action): Remove redundant arguments.

- * tests/regression.at (Braced code in declaration in rules section):
- Make yyerror and yylex static as usual.
-
-2006-06-24 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Fix bug that mistakes braced code in a declaration in the rules section
- to be a rule action. Mentioned at
- <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00105.html>.
- * src/scan-gram.l: Move midrule action detection from the start of the
- scanning of any braced code to...
- * src/parse-gram.y (rhs): ... the parsing of braced code as a rule
- action. For readability, use $2 and @2 rather than the equivalent
- global variables.
- * tests/regression.at (Braced code in declaration in rules section):
- New test to catch the error fixed by the above patch.
-
- Work on code readability some.
- * src/scan-code.l (current_rule): Get rid of this misleading and
- redundant declaration: it's actually extern'ed in reader.h.
- (YY_DECL, code_lex, handle_action_dollar, handle_action_at,
- translate_action): Add a rule argument and use it instead of the global
- current_rule.
- (translate_rule_action): This already receives current_rule through an
- argument, so pass it on to translate_action instead of assigning
- current_rule to current_rule.
- (translate_symbol_action, translate_code): Pass rule = NULL to
- translate_action.

- Don't put the pre-prologue in the header file. For the yacc.c code
- file and the glr.c header and code files, move the pre-prologue before
- the token definitions. Add new %before-definitions and

- both the header and code file.
- (b4_after_definitions): New right after YYLTYPE and yylloc in both the
- header and code file.

- of prologues for %union dependencies.
- (Decl Summary): In %defines description, mention the effect of
- %before-definitions and %after-definitions on the header file.

- The Translation Project changed its way of publishing translations
- to maintainers. I haven't received any responses to my request
- for supporting the old way, or for documenting the new way. I
- have modified 'bootstrap' to use screen scraping
- (in this case, HTML scraping). This is unreliable and inelegant,
- but I don't see any better way. Yuck.
- * bootstrap (TP_URL, WGET_COMMAND): New vars.
- (get_translations): New function, which uses HTML scraping to
- deduce locations of latest translations.
- Use this function to grab both bison and bison-runtime .po files.
- Don't bother priming the pump for the runtime-po domain any more,
- as it's now translated better than bison is.
-
-2006-06-19 Akim Demaille <akim@epita.fr>
-

- Remove this test case and copy to...
- (Early token definitions with --yacc): ... this to test #define's.
- (Early token definitions without --yacc): ... and this to test enums.

-
-2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
-
- * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
- shell, not within 'make', so that 'make' by an ordinary builder
- (using GNU make) does not worry about configuring gzip. This also
- works around a bug reported independently by Keith Thompson and by
- Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
- stderr rather than stdout, messing up the build logs.
-
-2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
- to make sure that YYID will never be unused. This fixes a 'make
- maintainer-check' failure caused by the recent changes to the 'Trivial
- grammars' test case, which caused g++ 4.1.0 to complain that YYID was
- not used.
- * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
-
-2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
- state before an empty RHS is always resolved here. Only the location
- of that state is guaranteed to be resolved, and that's enough. This
- fixes the remaining bug reported by Derek M. Jones in
- <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
- * tests/glr-regression.at (Uninitialized location when reporting
- ambiguity): Test the above case.
- Also, the embedded comments in this test case claim it checks the case
- of an empty RHS that has inherited the initial location. However, the
- corresponding LHS was already resolved, so yyresolveLocations didn't
- actually have reason to modify it. Fix this by forcing
- nondeterministic operation at the beginning of the parse.
-
-2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
-
- * data/c.m4 (b4_yy_symbol_print_generate):
- (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than

- of the bugs reported today by Derek M Jones in
- <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
- * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
- defined to be a type name without parens or brackets.
- (Location Type): Similarly for YYLTYPE.
- * tests/regression.at (Trivial grammars): Put in a test for this
- bug that will be caught by 'make maintainer-check' (though not,

- Remove the yyvalp and yylocp parameters since they are always just
- taken from the yys parameter. When reporting a discarded merged value
- in debugging output, note that it is incompletely merged. Document the
- interface.
- (yyresolveAction): If resolving any of the RHS states fails, destroy
- them all rather than leaking them. Thus, as long as user actions are
- written to clean up the RHS correctly, yyresolveAction always cleans up
- the RHS of a semantic option. Document the interface.

-
- During deterministic GLR operation, user actions should be able to
- influence the parse by changing yychar. To make this easier to fix and
- to make glr.c easier to evolve in general, don't maintain yytoken in

- Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
- got from <http://bro-ids.org/download.html>. The bug is that
- when two actions appeared in succession, the second one was
- scanned before the first one was added to the grammar rule

- * data/glr.c (yyresolveValue): When merging semantic options, if at

- yyresolveValue fails, ignore the (unset) semantic value rather than
- corrupting the yyGLRState, and empty the semantic options list since

- Use unlocked I/O for a minor performance improvement on hosts like

-
- * tests/regression.at (Token definitions): Don't rely on

- uses 'echo', and 'echo' isn't portable if its argument contains
- backslashes. Problem found on OpenBSD 3.4. Also, do not assume

-
-2005-07-21 Paul Eggert <eggert@cs.ucla.edu>
-
- * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
- again if the first call fails.
-
- * data/glr.c (yytnamerr): New function.
- (yyreportSyntaxError): Use it to dequote most string literals.
- * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
- with other skeletons. All uses changed.
- (yytnameerr_): New function.
- (yyreport_syntax_error): Use it to dequote most string literals.
- * data/yacc.c (yytnamerr): New function.
- (yyerrlab): Use it to decode most string literals.
- * doc/bison.texinfo (Decl Summary, Calling Convention):
- Clarify quoting convention of yytname.
- * src/output.c (prepare_symbols): Quote all names. This undoes
- the 2005-04-17 change, which is now accomplished (mostly) via
- changes in the parsers as described above.
- * tests/regression.at (Token definitions, Web2c Actions):
- Undo most 2005-04-17 change here, too.
-
-2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
-
- Fix more problems reported by twlevo@xs4all.nl.
- * tests/cxx-type.at: Don't pipe output of ./types through sed to
- remove trailing spaces. This loses the exit status of ./types,
- and isn't needed since ./types shouldn't be emitting trailing
- spaces.
- * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
- as the stack isn't valid in that case.
-
- * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
- (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
- (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
- Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
- is used.
- * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
- (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
- (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
- Likewise.
-
- * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
- overly-picky compilers that reject 'char *foo = "bar";'.
-
- * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
- to FILE * parameter, not to stderr. This fixes a typo introduced
- in the 2005-07-12 change.
-
- * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
- warnings from GCC 4.
-
- * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
- (yyglrShiftDefer, yysplitStack):
- Remove unused parameters b4_pure_formals. All uses changed.

- All uses changed.
- (yyglrReduce): Removed unused parameter yylocp. All uses changed.
-
-2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
-
- Destructor cleanups and regularization among the three skeletons.
- * NEWS: Document the behavior changes.
- * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
- stack before failing, as the cleanup code will do it for us now.
- * data/lalr1.cc (yyerrlab): Likewise.
- * data/glr.c (yyparse): Pop everything off the stack before
- freeing it, so that destructors get called properly.
- * data/lalr1.cc (yyreturn): Likewise.
- * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
- This is more consistent.
- * doc/bison.texinfo (Destructor Decl): Mention more reasons
- why destructors might be called. 1.875 -> 2.1.
- (Destructor Decl, Decl Summary, Table of Symbols):
- Some English-language cleanups for %destructor.
- * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
- Add output line for destructor of start symbol.
- * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
- because of that same extra output line.
-
- * NEWS: Document minor wording changes in diagnostics of
- Bison-generated parsers.
- * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
- Remove unused formals. All uses changed.
- (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
- (yyparse): Rename yyoverflowlab to yyexhaustedlab.
- * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
- Rename yyoverflowab to yyexhaustedlab.
- When memory exhaustion occurs during syntax-error reporting,
- report it separately rather than in a single diagnostic; this
- eases translation.
- * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
- (Memory Exhausted): Renamed from Parser Stack Overflow.
- Revamp wording slightly to prefer "memory exhaustion".
- * tests/actions.at: "parser stack overflow" -> "memory exhausted".
-
- * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
-
- Add i18n support to the GLR skeleton. Partially fix the C++
- skeleton; a C++ expert needs to finish this. Remove debugging
- msgids; there's little point to having them translated, since they
- can be understood only by someone who can read the
- (English-language) source code.
-
- Generate runtime-po/bison-runtime.pot automatically, so that we
- don't have to worry about garbage getting in that file. We'll
- make sure after the next official release that old msgids don't
- get lost. See
- <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
-
- * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
- Now auto-generated.
- * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
- Fix typos in explanations of the runtime file.
- * bootstrap: Change gettext keyword from YYI18N to YY_.
- Use standard Makefile.in.in in runtime-po, since we'll arrange
- for backward-compatible bison-runtime.po files in a different way.
- * data/glr.c (YY_): New macro, from yacc.c.
- (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
- Translate messages intended for users.
- (yyreportSyntaxError): Change "virtual memory" to "memory" to match
- the wording in the other skeletons. We don't know that the memory
- is virtual.
- * data/lalr1.cc (YY_): Renamed from _. All uses changed.
- Use same method that yacc.c uses.
- Don't translate debugging messages.
- (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
- it doesn't work (yet), and requires C++ expertise to fix.
- * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
- Move defn to a more logical place, to be consistent with other
- skeletons.
- Don't translate debugging messages.
- Don't assume line numbers fit in unsigned int; use unsigned long fmts.
- * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
- to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
- * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
-
- Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
- * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
- void, not int.
- * tests/glr-regression.at (Badly Collapsed GLR States):
- Likewise.
- (Improper handling of embedded actions and dollar(-N) in GLR parsers):
- yylex should return 0 at EOF rather than aborting.
-
- Improve tests for stack overflow in GLR parser.
- Problem reported by twlevo@xs4all.nl.
- * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
- All uses removed.
- (yyStackOverflow): Just longjmp, but with value 2 so that caller
- can handle the problem.
- (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
- (yyparse): New local variable yyresult to record the result.
- Use result of setjmp to set it, rather than storing itinto
- struct.
- (yyDone): Remove label.
- (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
- to mimic yacc.c. Do not discard lookahead if it's EOF (possible
- if YYABORT is used).
- * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
- yyparse status; put status > 1 into diagnostic.
- Check that status==2 works.
- * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
- Use exit status 3 for failure to open (which shouldn't happen).
-
-2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
-
- * tests/conflicts.at (%nonassoc and eof): Don't exit with status
- 1 on syntax error; just let yyparse do its thing.
- * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
- * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
- (Exploding the Stack Size with Alloca):
- (Exploding the Stack Size with Malloc):
- Expect exit status 2, not 1, since the parser is supposed to blow
- its stack. Problem reported by twlevo@xs4all.nl.
-
- * data/glr.c (yyparse): Don't assume that the initial calls
- to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
- Print a stack-overflow message and fail instead.
- Initialize the line-number information before creating the stack,
- so that the stack-overflow message can report line zero safely.
-
-2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
-
- Fix problems reported by twlevo@xs4all.nl.
- * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
- (yyuserMerge): Provide a default case if b4_mergers is empty.

- (Improper handling of embedded actions and dollar(-N) in GLR parsers):
- Add casts to pacify C++ compilers.
- * tests/glr-regression.at (Improper merging of GLR delayed action
- sets): Declare yylex before using it.
- * tests/Makefile.am (maintainer-check-g++): Fix a stray
- $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
- test for valgrind; valgrind is independent of g++.
- (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
- for compatibility with POSIX 1003.1-2001 (if running coreutils).
- * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
- Use a destructor, so that we can expand the stack. Change
- YYSTYPE to char * so that we can free it. Cast result of malloc.
-
-2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
-
- * data/glr.c (yyuserAction): Fix uninitialized variable that caused

-
- * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:

- * examples/calc++/Makefile.am (run_extexi): Remove; not used.
- ($(calc_extracted)): Renamed from $(calc_sources_extracted),
- so that we also get calc++-parser.yy. Geneate it.

- Put comment before action, since older 'make' can't handle comment
- in action.
- $(BUILT_SOURCES): List all built sources, not just some of them.
- $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
- $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.

-
-2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
-
- * data/glr.c (yyFail): Drastically simplify; since the format argument
- never had any % directives, we can simply pass it to yyerror.
- (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
- be modified later, as that is the usual style in glr.c.
- Problems reported by Paul Hilfinger.
-
- Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
- and size overflow errors.
- * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
- in case the user prolog sets feature-test macros like _GNU_SOURCE.
- (YYSIZEMAX): New macro.
- (yystpcpy): New function, taken from yacc.c.
- (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
- (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
- so that we don't have to maintain their signatures.
- (yyFail): Check for buffer overflow, by using vsnprintf rather
- than vsprintf. Allocate a bigger buffer if possible.
- Report an error if buffer allocation fails.
- (yyStackOverflow): New function.

- the initialization was successful. It might fail if storage was
- exhausted.
- (yyexpandGLRStack): Add more checks for storage allocation failure.

- (alloca): Include <stdlib.h> to get it, if it's not built in.
- (YYMALLOC, YYFREE): Define only if needed.

- * lib/subpipe.c: Include "unistd-safer.h".
- (create_subpipe): Make sure all the newly-created
- file descriptors are > 2, so that diagnostics don't

- don't set yychar to EMPTY.
- (yyoverflowlab): Don't call destructor.
- (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
- * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,

- From Marcus Holland-Moritz.
- * data/yacc.c (yyerrlab): Move the code that destroys the stack

-
-2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
-
- * src/parse-gram.y: Include quotearg.h.

- * tests/regression.at (Token definitions): Check for backslashes
- in token strings.
-
- * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.

- overflow. Change "virtual memory" to "memory" in diagnostic, since
- we don't know whether the memory is virtual.

- * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
-
- * tests/torture.at (Exploding the Stack Size with Alloca): Set

-
- * data/lalr1.cc (yydestruct_): Pacify unused variable warning
- for yymsg, too.

-
-2004-12-22 Paul Eggert <eggert@cs.ucla.edu>
-
- * NEWS: Bison-generated parsers no longer default to using the
- alloca function (when available) to extend the parser stack, due
- to widespread problems in unchecked stack-overflow detection.
- * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
- responsibility to set it to a positive value. This lets the user
- specify a value that is not a preprocessor constant.
- * data/yacc.c (YYMAXDEPTH): Likewise.
- (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
- * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs

- Also, explain the constraints on YYINITDEPTH.
- (Table of Symbols): Explain that alloca is no longer the default.
- Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
- to 1.
-
- * doc/bison.texinfo (Location Default Action): Mention that n must

- (parser::state_type, parser::semantic_type, parser::location_type):
- Private, not public.
- (parser::parse): Return ints, not bool.
- Returning a bool introduces a problem: 0 corresponds to false, and
- it seems weird to return false on success. Returning true changes
- the conventions for yyparse.
- Alternatively we could return void and send an exception.
- There is no clear consensus (yet?).
- (state_stack, semantic_stack, location_stack): Rename as...

- included first.
- Forward declare them before the user code.
- * tests/Makefile.am (check-local, installcheck-local): Pass
- TESTSUITEFLAGS to the TESTSUITE.
-
-2004-12-20 Akim Demaille <akim@epita.fr>

-2004-12-17 Paul Eggert <eggert@cs.ucla.edu>
-
- Remove uses of 'short int' and 'unsigned short int'. This raises
- some arbitrary limits. It uses more memory but nowadays that's
- not much of an issue.
-
- This change does not affect the generated parsers; that's a different
- task, as some users will want to conserve memory there.
-
- Ideally we should use size_t to represent all object counts, and
- something like ptrdiff_t to represent signed differences of object
- counts; but that will require more code-cleanup than I have the
- time to do right now.
-

-
- Fix some problems reported by twlevo at xs4all.
- * src/symtab.c (symbol_new): Report an error if the input grammar

- (struct node, struct graph):
- Rename member expand to stretch. All uses changed.
- (struct graph): Remove member layoutalgorithm. All uses removed.

-2004-12-15 Akim Demaille <akim@epita.fr>
-
- Simplify the C++ parser constructor.
-
- * data/lalr1.cc (debug_): Rename as...

- pseudo namespace.
- Adjust uses.
- (b4_parse_param_decl): Remove the leading comma as it is now only
- called as unique argument list.
- (Parser::Parser): Remove the constructor accepting a location and
- an initial debugging level.
- Remove from the other ctor the argument for the debugging level.

- definitions and uses.
-
-2004-12-14 Paul Eggert <eggert@cs.ucla.edu>
-
- * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
- not 2, since it's not portable to subtract 1 from the start of an
- array. The new item 0 is never set or used. All uses changed.
-
- (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming
- the default definition of YYLLOC_DEFAULT. Problem reported
- by Frank Heckenbach.
-
-2004-12-12 Paul Eggert <eggert@cs.ucla.edu>
-
- * data/glr.c (YYRHSLOC): Don't have two definitions, one for
- the normal case and one for the error case. Just use the
- first one uniformly. Problem reported by Frank Heckenbach.
- (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
- use exactly the same macro in both places.
- (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
- so that the normal-case YYRHSLOC works for the error case too.
- All uses changed.
- * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
- (YYLLOC_DEFAULT): Use the same macro as glr.c.
- * doc/bison.texinfo (Location Default Action): Don't claim that

-
-2004-12-08 Paul Eggert <eggert@cs.ucla.edu>

-2004-12-07 Paul Eggert <eggert@cs.ucla.edu>
-
- * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
- * src/lalr.c (set_goto_map): Don't allow ngotos to equal

- have an accurate range, equivalent to the one computed by both
- yacc.c and lalr1.cc.
- * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
- that column numbers start at column 0, as per GNU Coding
- Standards, the others tests, and the doc.
- (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
- Adjust to the above change (first column is 0).
- And adjust the location of the "<error>", now covering the whole
- line.
-
-2004-10-22 Akim Demaille <akim@epita.fr>
- and Paul Eggert <eggert@cs.ucla.edu>
-
- Remove some arbitrary limits on goto numbers and relations.
- * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
- initial values, since they're never used.
- (set_goto_map): ngotos is now unsigned, so test for overflow
- by seeing whether it wraps around to zero.
- * src/lalr.h (goto_number): Now size_t, not short int.
- (GOTO_NUMBER_MAXIMUM): Remove.
- * src/relation.c (relation_print, traverse, relation_transpose):

- * doc/bison.texinfo (Language and Grammar): In example, "int" is a
- keyword, not an identifier. Problem reported by Baron Schwartz in
- <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
-
-2004-10-11 Akim Demaille <akim@epita.fr>

- spaces.
-
-2004-10-05 Akim Demaille <akim@epita.fr>
-
- In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
- whether the reducion was empty or not. This leaves room to
- improve the use of YYLLOC_DEFAULT in such a case.
- lalr1.cc is still experimental, so changing this is acceptable.
- And finally, there are probably not many users who changed the
- handling of locations in GLR, so changing is admissible too.
-
- * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
- empty reduction, set @$ to an empty location ending the previously
- stacked symbol.
- Adjust uses to make sure the code is triggered on empty
- reductions.
- * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
- expected output: empty reductions have empty locations.
-
-2004-09-29 Akim Demaille <akim@epita.fr>
-
- * data/lalr1.cc: Move towards a more standard C++ coding style
- for templates: Class < T > -> Class<T>.
-
-2004-09-29 Akim Demaille <akim@epita.fr>
-
- * data/lalr1.cc: Reinstall the former ctor, for sake of
- compatibility, but warn it will be removed.
- Move towards a more standard C++ coding style (i.e., type *var ->
- type* var).
-
-2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
-
- * src/parse-gram.y (add_param): Rewrite to avoid strchr,
- since it's less likely to work if NULs are involved in the future.

- the useless parentheses.
- Suggested by Paul Eggert.
-
-2004-09-20 Akim Demaille <akim@epita.fr>
-
- Let the initial-action act on the look-ahead, and use it for the
- "initial push" (corresponding to an hypothetical beginning-of-file).
- And let lalr1.cc honor %initial-action.
-
- * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
- example.
- * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
- (Parser::Parser): Remove the ctor that used to initialize it.
- (Parser::parse): Like in the other skeletons, issue the "starting
- parse" message before any action.

-2004-09-20 Akim Demaille <akim@epita.fr>
-
- * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
- clearer criterion to define it.
- (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
- When reducing on an empty RHS, use the latest stacked location as
- location.
- yylloc is not always available.
- * data/glr.c: Likewise.
- Also, honor initial-actions.
-
-2004-09-20 Akim Demaille <akim@epita.fr>
-
- * data/yacc.c (YY_LOCATION_PRINT): New.
- Define when we know YYLTYPE's structure, i.e., when the default
- YYLLOC_DEFAULT is used.
- * data/c.m4 (b4_yysymprint_generate): Use it.
- * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
- value of the result.
- (error_start_): Replace with...
- (error_range_): this location array.
- This allows to replace code relying on the implementation of
- locations by portable code.
- * data/yacc.c (yylerrsp): Replace with...
- (yyerror_range): this.
- Every time a token is popped, update yyerror_range[0], to have an
- accurate location for the error token.
- * data/glr.c (YY_LOCATION_PRINT): New.
- (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
- deference a pointer.
- * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
- report the location in %printers.
-
- * src/scan-skel.l: Instead of abort, report error messages to ease

-
-2004-09-16 Akim Demaille <akim@epita.fr>
-
- * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
- (iterator, const_iterator): these, to be more in the C++ spirit.
- Also, return reverse iterators so that when displaying the stack
- we display its bottom first.
- (Parser::stack_print_, Parser::reduce_print_): Match the messages
- from yacc.c.
- We should probably use vector here though.
-
-2004-09-16 Akim Demaille <akim@epita.fr>
-
- Have more complete shift traces.
-
- * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
- to report Shifts instead of ad hoc YYDPRINTF invocations,
- including for the error token.
- * data/lalr1.cc (symprint_): Output the location.
- * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
- output the location within the %printer.
- Activate GLR tests, at least to make sure they compile properly.
- They still don't pass though.
- * tests/calc.at: Adjust expect verbose output, since now "Entering
- state..." is on a different line than the "Shifting" message.
-
-2004-09-08 Akim Demaille <akim@epita.fr>
-
- * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
- Bison directive from the Bison file to the invocation of this
- macro, so that these directives are passed to
- AT_BISON_OPTION_PUSHDEFS to get correct help macros.
- Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
- Move the AT_SETUP/AT_CLEANUP outside, to report as test title
- the extra Bison directives instead of the whole series.
- Change the grammar so that there are recoverable errors, and
- unrecoverable errors. Now we can have the parser give up before
- consuming the whole input. As a result we now can observe that
- the lookahead is freed when needed.
- Change the parser source to parse argv[1] instead of a hard coded
- string.
- Simplify yylex, and give a value and location to EOF.
- Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
- passed directives already coded in the file.
- Add some tests to check the location of "error".
- For some tests, the C++ parser is correct, and not yacc.c.
- For other tests, they provide different, but unsatisfying, values,
- so keep the C++ value so that at least one parser is "correct"
- according to the test suite.
- (Actions after errors): Remove, this is subsumed by the
- AT_CHECK_PRINTER_AND_DESTRUCTOR series.
-
-2004-09-06 Akim Demaille <akim@epita.fr>

- argument, an informative message.
- Call YY_SYMBOL_PRINT.
- Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
- * data/lalr1.cc (destruct_): Likewise.
- In addition, no longer depend on b4_yysymprint_generate and
- b4_yydestruct_generate to generate these functions, do it "by
- hand".
-
-2004-09-03 Akim Demaille <akim@epita.fr>
-
- * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
- invoked, yydestruct the lookahead.

- one.
-
-2004-09-02 Akim Demaille <akim@epita.fr>
-
- * data/lalr1.cc (b4_yysymprint_generate): New.
- (symprint_): New member function, defined when YYDEBUG.
- Use it consistently instead of token/nterm debugging output by
- hand.
- * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
- %printer calls to use cdebug_ when using lalr1.cc.
-
-2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
-
- * data/glr.c: Guard the declarations of yypstack and yypdumpstack

- C++ compiler. (trivial change)
-
-2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
-
- Spent a few hours checking out which prerequisite versions the
- current sources actually require. I went all the way back to
- Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
- a seemingly endless set of combinations of versions more recent
- than that. The bottom line is that the current sources require
- fairly recent versions of the build tools, and it'll be some work
- to change this.
- * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
- (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
- (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
- Add comments explaining why those particular versions are
- currently needed.

- * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
- in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
- <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
-
- * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
- (it fails with a Autoconf-without-aclocal-m4 diagnostic).
-
-2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
-
- * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
- 0.11.5. Suggested by Bruno Haible.
- * bootstrap: Remove gettext version checking.
-
- * doc/bison.texinfo (Decl Summary): Also mention that %union
- can depend on prerequisite types. Problem reported by Tim
- Van Holder.
-
-2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
-
- * README: Mention GNU m4 1.4 bugs and Akim's patched version.

- gettext better.
-
- * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
- put into the -d output file, and mention what to do if YYSTYPE is
- defined as a macro.
-
-2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
-
- Undo change made earlier today: it caused autopoint to not bring
- in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
- autopoint's.
-
- * bootstrap: Check that gettext version matches what's in
- configure.ac. Warn users to ignore robots.txt ERROR 404.
- * bootstrap: Undo today's earlier change (logged below).
- * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
-
- The gettext version checking is causing more trouble than it's
- curing; remove it. Problem reported by Paul Hilfinger.
-
- * bootstrap: Issue a warning that one can expect a message
- 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
- * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
-
-2004-05-23 Paul Eggert <eggert@cs.ucla.edu>

- supported by GCC 3.4.0.
- * README: Mention GNU m4 1.4 or later; mention m4 patches.
- * HACKING: Use ./bootstrap, not "make update" to import foreign files.
-

- gets copied to the output file.
-
-2004-04-28 Paul Eggert <eggert@twinsun.com>
-
- Get files from the gnulib and po repositories, instead of relying
- on them being in our CVS. Upgrade to latest versions of gnulib
- and Automake.
-
- * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
- * bootstrap: Bootstrap from gnulib and po repositories.
- Much of this code was stolen from GNU diff and GNU tar's bootstrap.
- * README-cvs: Document these changes. Remove version numbers from
- mentions of build tools, since they change so often. Mention Flex.
-
- * configure.ac (AC_CONFIG_MACRO_DIR): Add, with m4 as arg.
- (gl_USE_SYSTEM_EXTENSIONS): Add.
- (AC_GNU_SOURCE, AC_AIX, AC_MINIX):

- ancient OS, as it gets in the way of latest Autoconf & gnulib.
- (AC_HEADER_STDC): Remove: we now assume C89 or better.

- by the Yacc library and must port to K&R hosts.
- (AC_CHECK_FUNCS_ONCE): Use instead of AC_CHECK_FUNCS.
- Do not check for C89 functions, except for setlocale which is
- used by the Yacc library.

- for us.
-
- * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".
- (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):
- Define to empty, as gnulib.mk will do the rest for us.
- ($(libbison_a_OBJECTS), stdbool.h): Remove, as gnulib.mk does this
- for us.
- (libbison_a_SOURCES): Define to $(lib_SOURCES) now.

-
- When reducing initial empty rules, Bison parser read an initial
- location that is not defined. This results in garbage, and that
- affects Bison's own parser. Therefore we need (i) to extend Bison
- to support a means to initialize this location, and (ii) to use
- this CVS Bison to fix CVS Bison's parser.

- Also, augment the similarity between lalr1.cc and yacc.c.
- Note: the locations of error recovery rules are not correct yet.

- * data/lalr1.cc: Comment changes to augment the similarity between
- lalr1.cc and yacc.c.
- (YYERROR): Goto to yyerrorlab, not yyerrlab1.
- (yyerrlab1): Remove, but where it used to be (now the bottom part of
- yyerrlab), when hitting EOF, pop the whole stack here instead of
- merely falling thru the default error handling mechanism.
- (yyerrorlab): New label, with the old contents of YYERROR,
- plus the following change: pop the stack of rhs corresponding
- to the production that invoked YYERROR. That is how Yacc
- behaves (required by POSIX).

- fail.
-
-2003-08-25 Akim Demaille <akim@epita.fr>

-
-2003-06-02 Paul Eggert <eggert@twinsun.com>
-
- * data/lalr1.cc (yy::Position::lines, yy::Position::columns,

-
-2003-06-01 Paul Eggert <eggert@twinsun.com>
-

-
- Fix a GLR parser bug I reported in February; see
- <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
- The problem was that GLR parsers did not conform to the C standard,
- because actions like { $1 = $2 + $3; } expanded to expressions
- that invoked YYFILL in separate subexpressions, and YYFILL assigned
- to a local variable. The C standard says that expressions
- like (var = f ()) + (var = f ()) have undefined behavior.
- Another problem was that GCC sometimes issues warnings that
- yyfill and its parameters are unused.
-
- * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
- as possibly unused.
- (yyfill): New function.
- (YYFILL): Use it.
- (yyuserAction): Change type of yynormal to bool, so that it matches
- the new yyfill signature. Mark it as possibly unused.
-
-
- Follow up on a bug I reported in February, where a Bison-generated
- parser can loop. Provide a test case and a fix for yacc.c. I
- don't have a fix for lalr1.cc or for glr.c, unfortunately.
- The original bug report is in:
- <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
-
- * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
- macro's size was becoming unwieldy.
- (yyerrlab): Do not discard an empty lookahead symbol, as this
- might destroy garbage.
- (yyerrorlab): New label, with the old contents of YYERROR,
- plus the following change: pop the stack of rhs corresponding
- to the production that invoked YYERROR. That is how Yacc
- behaves, and POSIX requires this behavior.
- (yyerrlab1): Use YYPOPSTACK instead of its definiens.
- * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
- Define 'alarm' to do nothing if unistd.h is not available.
- Add a new rule "exp: '-' error;" to test the above change to
- data/yacc.c. Use 'alarm' to abort any test taking longer than
- 10 seconds, as it's probably looping.
- (AT_CHECK_CALC): Test recovery from error in new grammar rule.
- Also, the new yacc.c generates two fewer diagnostics for an
- existing test.
-
-2003-05-24 Paul Eggert <eggert@twinsun.com>
-
- * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
- YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
- This fixes a problem reported by John Bowman when the Compaq/HP
- Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
- -ansi -Wall -gall).
- * data/yacc.c (union yyalloc): Likewise.
- (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
-
- Switch from 'int' to 'bool' where that makes sense.

- semicolon after a grammar declaration, in the interest of possible
- future changes to the Bison input language.
- Do not allow a stray semicolon at the start of the grammar.
- (rhses.1): Allow one or more semicolons after any rule, including

- grammar.
-
-2003-05-14 Alexandre Duret-Lutz <adl@gnu.org>
-
- %parse-param support for lalr1.cc.

-
-2003-05-12 Paul Eggert <eggert@twinsun.com>
-
- * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
- English a bit. Fix fclose typo. Change "const char" to "char
- const", and use ANSI C rather than K&R for "main". Suggest
- YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
- and suggest yy_switch_to_buffer.
-
-2003-05-05 Paul Eggert <eggert@twinsun.com>
-
- * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
- C89. This avoids a diagnostic on compilers that define __STDC__
- to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
- <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
-
-2003-05-03 Paul Eggert <eggert@twinsun.com>
-
- * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
- Do not overrun array bounds.
- This should fix a bug reported today by Olatunji Oluwabukunmi in
- <http://lists.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
-
-2003-04-29 Akim Demaille <akim@epita.fr>
-
- * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
- * src/getargs.c, src/getargs.h: here, as bool, not int.
- (nondeterministic_parser): New.
- * src/parse-gram.y, src/scan-gram.l: Support
- %nondeterministic-parser.
- * src/output.c (prepare): Use nondeterministic_parser instead
- of glr_parser where appropriate.
- * src/tables.c (conflict_row, action_row, save_row)
- (token_actions, token_actions, pack_vector): Ditto.

- with %pure-parser and %locations to exercise the patch from Yakov
- Markovitch below.
-
-2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
-
- * data/yacc.c: (b4_lex_param): Corrected for the case where

-
-2003-04-27 Paul Eggert <eggert@twinsun.com>
-
- Avoid gcc -Wundef warnings reported by Gerald Pfeifer in

-2003-04-26 Paul Eggert <eggert@twinsun.com>
-
- * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
- Declare to be of type suitable for the ninf value itself, not of
- type suitable for the corresponding table, since the latter might
- be unsigned but the ninf value might be negative. This fixes a
- bug reported by Alexandre Duret-Lutz in
- <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
-
- * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
- invokes it. We shouldn't invoke it twice because it will attempt
- to put error.o in the archive twice. This fixes a glitch reported
- by Martin Mokrejs in
- <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
-
-2003-04-21 Paul Eggert <eggert@twinsun.com>
-

-
- * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
- Fix obvious typo that results in uncompilable GLR parsers
- when both %pure-parser and %locations are used. (trivial change)
-
-2003-04-17 Paul Eggert <eggert@twinsun.com>
-
- * src/scan-gram.l: Add %option nounput, since we no longer use unput.
- (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
- Do not insert the expected token via unput, as this runs afoul
- of a POSIX-compatibility bug in flex 2.5.31.
- All uses changed to BEGIN the parent state,
- since we no longer insert the expected token via unput.
- * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
- that is no longer emitted after the above change.
-
- * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
- the first one. This change is from Paul Hilfinger, and it fixes
- regression reported by Werner Lemberg in
- <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
-
- (resolve_sr_conflict): Don't invoke state_errs_set
- unless one or more tokens have been explicitly made errors.
- Otherwise, the above change causes Bison to abort.
-

- * m4/error.m4: Do not put under dynamic conditions some code which
- expansion is under static control.
-
-2003-03-29 Akim Demaille <akim@epita.fr>
-
- * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.

-2003-03-12 Paul Eggert <eggert@twinsun.com>
-
- * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
- (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
- cursor, instead of leaving it undefined. This fixes a bug
- reported by Tim Van Holder in
- <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
- * tests/input.at (Torturing the Scanner): Test the scanner on
- an empty input file, which was Tim Van Holder's test case.
-
- * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
- <sys/resource.h> can be included, include sys/time.h and
- sys/times.h first, if available. This works around the SunOS
- 4.1.4 porting bug reported by Bruce Becker in
- <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
-
- * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
- AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
- AC_HEADER_SYS_WAIT.
-
- Merge changes from gnulib. This was prompted because the CVS
- snapshot didn't build on Solaris 7 due to strnlen problems.
-
- These changes need to be merged back into gnulib:
- * lib/hash.c: Include <stdbool.h> unconditionally.
- * m4/onceonly.m4 (m4_quote): New macro.

-
-2003-03-01 Paul Eggert <eggert@twinsun.com>
-
- * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
- not loc->end, since loc->end might contain garbage and this leads
- to undefined behavior on some platforms.
- (id_loc, token_start): Use (IF_LINTed) initial values that do not
- depend on *loc, so that the reader doesn't give the the false
- impression that *loc is initialized.
- (<INITIAL>"%%"): Do not bother setting code_start, since its value
- does not survive the return.
-
-2003-03-01 Akim Demaille <akim@epita.fr>
-
- * src/scan-gram.l (code_start): Always initialize it when entering
- into yylex, as SC_EPILOGUE is activated *before* the corresponding
- yylex invocation. An alternative would be making it static, but
- then it starts with the second %%'s beginning, instead of its end.
-
-2003-02-28 Paul Eggert <eggert@twinsun.com>
-
- * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
- around a UnixWare 7.1.1 porting bug reported by John Hughes in

-
-2003-02-17 Paul Eggert <eggert@twinsun.com>
-
- * tests/atlocal.in (LDFLAGS, LIBS): New vars.
- * tests/testsuite.at (AT_COMPILE): Use them.

-
-2003-02-02 Akim Demaille <akim@epita.fr>
-
- * src/scan-skel.l: Scan more than one inert character per yylex
- invocation.
-
-2003-02-01 Paul Eggert <eggert@twinsun.com>
-
- Version 1.875a.
-
- * po/LINGUAS: Add ms.
-
-2003-01-30 Akim Demaille <akim@epita.fr>
-
- * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
-
-2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
-
- * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
- of $1.
-
- Changes in response to error report by S. Eken: GLR mode does not
- handle negative $ indices or $ indices in embedded rules correctly.
- See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
-
- * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
- (b4_rhs_location): Ditto.
- (yyfill): New function to copy from stack tree into array
- incrementally.
- (yyuserAction): Modify to allow incremental move of semantic values
- to rhs array when in GLR mode.
- Define YYFILL to use in user-defined actions to fill semantic array
- as needed.
- Remove dummy use of yystack, as there is now a guaranteed use.
- (yydoAction): Modify to allow incremental move of semantic values
- to rhs array when in GLR mode.
- (yyresolveAction): Ditto.
- (yyglrShiftDefer): Update comment.

-2003-01-28 Paul Eggert <eggert@twinsun.com>
-
- * data/lalr1.cc: Do not use @output_header_name@ unless
- b4_defines_flag is set. This fixes two bugs reported by
- Tim Van Holder in
- <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
- and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
-
-2003-01-21 Paul Eggert <eggert@twinsun.com>
-
- * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
- we don't need to worry about yyerrlab1 being reported as an
- "unused label" by non-GCC C compilers. The downside is that if
- locations are used then a couple of statements are duplicated each
- time YYERROR is invoked, but the upside is that the warnings
- should vanish.
- (yyerrlab1): Move code to YERROR.
- (yyerrlab2): Remove. Change uses back to yyerrlab1.
- This reverts some of the 2002-12-27 change.
-
-2003-01-17 Paul Eggert <eggert@twinsun.com>
-
- * src/output.c (symbol_printers_output): Fix typo that led
- to core dump. Problem reported by Antonio Rus in
- <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.

-2003-01-13 Akim Demaille <akim@epita.fr>,
- Quoc Peyrot <chojin@lrde.epita.fr>,
- Robert Anisko <anisko_r@lrde.epita.fr>
-
- * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
- when the stacks contain one element, as the loop would otherwise
- free the last state, and then use the top state (the one we just
- popped). This means that the initial elements will not be freed
- explicitly, as is the case in yacc.c; it is not a problem, as
- these elements have fake values.
-
-2003-01-11 Paul Eggert <eggert@twinsun.com>
-
- * NEWS: %expect-violations are now just warnings, reverting
- to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
- bootstrapping problem reported by Matthias Klose; see
- <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
- * src/conflicts.c (conflicts_print): Likewise.
- * tests/conflicts.at (%expect not enough, %expect too much,
- %expect with reduce conflicts): Likewise.
- * doc/bison.texinfo (Expect Decl): Document this. Also mention
- that the warning is enabled if the number of conflicts changes
- (not necessarily increases).
-
- * src/getargs.c (version): Update copyright year.
-
-2003-01-09 Akim Demaille <akim@epita.fr>
-
- * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
-
-2003-01-08 Paul Eggert <eggert@twinsun.com>
-
- * Makefile.maint (WGETFLAGS):
- New macro, containing "-C off" to disable proxy caches.
- All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
- (rel-check): Use $(WGET) instead of wget.
-
-2003-01-06 Paul Eggert <eggert@twinsun.com>
-
- * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
- the GLR paper of Scott, Johnstone and Hussain.

-
- * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
- (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
- * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
- (EXTRA_LIBRARIES): New var, for liby.a.
- * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
- (EXTRA_SCRIPTS): New var, for yacc.
-
- * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
- since GNU C++ (as of 3.2.1) does not allow attributes on labels.
- Problem reported by Nelson H. F. Beebe.
-
-2003-01-03 Paul Eggert <eggert@twinsun.com>
-
- * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
- (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
- when compiling Bison 1.875's `bitset bset = obstack_alloc
- (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
-
- * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
- ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
- grow to a huge size with typical invocation.
-
- * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
- Use the pattern recommended by Autoconf 2.57, except also protect
- against double-definition.
- * src/system.h: Likewise.
- Portability issues reported by Nelson H. F. Beebe.
-
- * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
- All uses changed. Provide a definition in both C and C++.
- (yytrue, yyfalse): Define even if defined (__cplusplus).
-
- * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
- Reported by Nelson H. F. Beebe.

-
-2003-01-02 Paul Eggert <eggert@twinsun.com>

- pacify the buggy "smart preprocessor" in MacOS 10.2.3.
- Bug reported by Nelson H. F. Beebe.
-
-2003-01-01 Paul Eggert <eggert@twinsun.com>
-
- * Version 1.875.
-
-2002-12-30 Paul Eggert <eggert@twinsun.com>
-
- * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
- Moved here from...
- (<INITIAL>","): Here. This causes stray "," to be treated
- more uniformly.
-
- * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
- last brace in braced code when not in Yacc mode, for compatibility
- with Bison 1.35. This resurrects the 2001-12-15 patch to
- src/reader.c.
-
- * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
- yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
-
-2002-12-28 Paul Eggert <eggert@twinsun.com>
-
- * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
- that of SYM's type. This fixes Debian bug 168069, reported by
- Thomas Olsson.
-
-2002-12-28 Paul Eggert <eggert@twinsun.com>
-
- Version 1.75f.
-
- Switch back to the Yacc style of conflict reports, undoing some
- of the 2002-07-30 change.
- * doc/bison.texinfo (Understanding): Use Yacc style for
- conflict reports. Also, use new way of locating rules.
- * src/conflicts.c (conflict_report):
- Renamed from conflict_report_yacc, removing the old
- 'conflict_report'. Translate the entire conflict report at once,
- so that we don't assume that "," has the same interpretation in
- all languages.
- (conflicts_output): Use Yacc-style conflict report for each state,
- instead of our more-complicated style.
- (conflicts_print): Use Yacc-style conflict report, except print
- the input file name when not emulating Yacc.
- * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
- Conflicted Reduction, %expect not enough, %expect too much,
- %expect with reduce conflicts): Switch to Yacc-style conflict reports.
- * tests/existing.at (GNU Cim Grammar): Likewise.
- * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
-
- * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
- fatal): Don't invoke fflush; it's not needed and it might even be
- harmful for stdout, as stdout might not be open.
- * src/reduce.c (reduce_print): Likewise.
-
-2002-12-27 Paul Eggert <eggert@twinsun.com>
-
- Fix a bug where error locations were not being recorded correctly.
- This problem was originally reported by Paul Hilfinger in
- <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
-
- * data/yacc.c (yyparse): New local var yylerrsp, to record the
- top of the location stack's error locations.
- (yyerrlab): Set it. When discarding a token, push its location
- onto yylerrsp so that we don't lose track of the error's end.
- (yyerrlab1): Now is only the target of YYERROR, so that we can
- properly record the location of the action that failed. For GCC
- 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
- GCC warning about yyerrlab1 being unused if YYERROR is unused.
- (yyerrlab2): New label, which yyerrlab now falls through to.
- Compute the error's location by applying YYLLOC_DEFAULT to
- the locations of all the symbols that went into the error.
- * doc/bison.texinfo (Location Default Action): Mention that
- YYLLOC_DEFAULT is also invoked for syntax errors.
- * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
- Error locations include the locations of all the tokens that were
- discarded, not just the last token.
-
-2002-12-26 Paul Eggert <eggert@twinsun.com>
-
- * src/files.c: Include quote.h.
- (compute_output_file_names): Warn if we detect conflicting
- outputs to the same file. This should catch the misunderstanding
- exemplified by Debian Bug 165349, reported by Bruce Stephens..
-
- * src/conflicts.c (conflicts_print): If the user specifies
- "%expect N", report an error if there are any reduce/reduce
- conflicts. This is what the manual says should happen.
- This fixes Debian bug 130890, reported by Anthony DeRobertis.
- * tests/conflicts.at (%expect with reduce conflicts): New test.
-
- Don't use m4_include on relative file names, as it doesn't work as
- desired if there happens to be a file with that name under ".".
-
- * m4sugar/version.m4: Remove; it was included but it wasn't used.
- * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
- * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
- * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
- * src/output.c (output_skeleton): Use full path names when
- specifying a file to include; don't rely on include path, as
- it's unreliable when the working file contains a file with
- that name.
-
-2002-12-25 Paul Eggert <eggert@twinsun.com>
-
- Remove obsolete references to bison.simple and bison.hairy.
- Problem mentioned by Aubin Mahe in
- <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
- * data/glr.c: Comment fix.
- * doc/bison.1: Remove references. Also, mention "yacc".
-
- * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
- with -g option.
-
- * src/parse-gram.y (declaration): Use enum "report_states" rather
- than its numeric value 1.
-
- * src/scan-skel.l ("@output ".*\n): Close any old yyout before
- opening a new one. This fixes Debian bug 165349, reported by
- Bruce Stephens.
-
-2002-12-24 Paul Eggert <eggert@twinsun.com>
-
- Version 1.75e.
-
- * Makefile.maint (cvs-update): Don't assume that the shell
- supports $(...), as Solaris sh doesn't.
-
- * src/parse-gram.y (lloc_default): Remove test for empty
- nonterminals at the end, since it didn't change the result.
-
-2002-12-24 Paul Eggert <eggert@twinsun.com>
-
- If the user does not define YYSTYPE as a macro, Bison now declares it
- using typedef instead of defining it as a macro. POSIX requires this.
- For consistency, YYLTYPE is also declared instead of defined.
-
- %union directives can now have a tag before the `{', e.g., the
- directive `%union foo {...}' now generates the C code
- `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
- The default union tag is `YYSTYPE', for compatibility with Solaris 9
- Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
- instead of `yyltype'.
-
- `yystype' and `yyltype' are now obsolescent macros instead of being
- typedefs or tags; they are no longer documented and will be
- withdrawn in a future release.
-
- * data/glr.c (b4_location_type): Remove.
- (YYSTYPE): Renamed from yystype.
- (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
- (struct YYLTYPE): Renamed from struct yyltype.
- (YYLTYPE): Renamed from yyltype.
- (yyltype, yystype): New (and obsolescent) macros,
- for backward compatibility.
- * data/yacc.c: Likewise.
-
- * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
- does not specify a union tag. This is for compatibility with
- Solaris 9 yacc.
-
- * src/parse-gram.y (add_param): 2nd arg is now char * not char
- const *, since it is now modified by stripping surrounding { }.
- (current_braced_code): Remove.
- (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
- PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
- trailing " {...}". Now of type <chars>.
- (grammar_declaration): Adjust to bundled tokens.
- (code_content): Remove; stripping is now done by add_param.
- (print_token_value): Print contents of bundled tokens.
- (token_name): New function.
-
- * src/reader.h (braced_code, current_braced_code): Remove.
- (token_name): New decl.
-
- * src/scan-gram.l (handle_dollar, handle_at): Now takes int
- token_type, not braced_code code_kind. All uses changed.
- (SC_PRE_CODE): New state, for scanning after a keyword that
- has (or usually has) an immediately-following braced code.
- (token_type): New local var, to keep track of which token type
- to return when scanning braced code.
- (<INITIAL>"%destructor", <INITIAL>"%lex-param",
- <INITIAL>"%parse-param", <INITIAL>"%printer",
- <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
- instead of returning a token type immediately.
- (<INITIAL>"{"): Set token type.
- (<SC_BRACED_CODE>"}"): Use it.
- (handle_action_dollar, handle_action_at): Now returns bool
- indicating success. Fail if ! current_rule; this prevents a core dump.
- (handle_symbol_code_dollar, handle_symbol_code_at):
- Remove; merge body into caller.
- (handle_dollar, handle_at): Complain in invalid contexts.
-
- * NEWS, doc/bison.texinfo: Document the above.
- * NEWS: Fix years and program names in copyright notice.
-
-2002-12-17 Paul Eggert <eggert@twinsun.com>
-
- * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
- Reporting, Table of Symbols): Omit mentions of %lex-param and
- %parse-param from the documentation for now.
-
-2002-12-15 Paul Eggert <eggert@twinsun.com>
-
- Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
- GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
- lookahead symbol, and which sets yychar in parser actions) and it
- disagreed with the Bison documentation. Bug
- reported by Andrew Walrond.
-
- * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
- as the caller now does that.
- (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
- (YYEMPTY): Parenthesize right hand side, since others use it.
- (yyparse): Don't assume that our generated code is the only code
- that sets yychar.
-
-2002-12-13 Paul Eggert <eggert@twinsun.com>
-

- locations are requested.
-
-2002-12-12 Paul Eggert <eggert@twinsun.com>
-

-
- * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
-
- * src/derives.c (derives_compute): Do not subtract NTOKENS from

-
- * src/gram.h (int_of_rule_number): Remove; no longer used.

- Likewise.

-
- * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local

- have to worry about alloca.
- * src/state.c (state_hash_lookup): Likewise.
-
- * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
- local var instead of casting to unsigned char, to avoid casts.
-
- * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
- STATE_ALLOC): Remove.
- (transitions_new, errs_new, reductions_new, state_new): Use malloc
- rather than calloc, and use offsetof to avoid allocating slightly
- too much storage.
- (state_new): Initialize all members.
-
- * src/state.c (state_hash): Use unsigned accumulator, not signed.
-
- * src/symtab.c (symbol_free): Remove; unused.

- be declared before being used. E.g., one should typically
- declare them in the prologue. Use GNU coding style in examples.
- Put "const" consistently after the type it modifies. Mention
- that C99 supports "inline". Mention that yyerror traditionally
- returns "int".

- unnecessarily alarming people when the test fails.
-
- * data/yacc.c (yyerrlab1): Move this label down, so that the
- parser does not discard the lookahead token if the user code
- invokes YYERROR. This change is required for POSIX conformance.

- * tests/headers.at (export YYLTYPE): Likewise.
-
- * tests/input.at (Torturing the Scanner): Remove lines containing

-
- * Makefile.maint (po-check): Scan .l and .y files instead of the

- Revamp to fix many (but not all) of the C- and M4-related quoting
- problems. Among other things, this fixes the Bison bug reported
- by Jan Hubicka when processing the Bash grammar; see:
- <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
-
- Use new @ escapes consistently. Represent brackets with @{ and @}
- rather than @<:@ and @:>@, since this works a bit better with dumb
- editors like vi. Represent @ with @@, since @ is now consistently
- an escape. Use @oline@ and @ofile@ rather than __oline__ and
- __ofile__, to avoid unexpected expansions. Similarly, use @output
- rather than #output.
-
- * data/c.m4 (b4_copyright): Omit file name from comment, since
- the file name could contain "*/".
- (b4_synclines_flag): Don't quote the 2nd argument; it should already

- (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,

-
- * src/files.c (output_infix): Remove; all uses removed.

- needed any more.
- * data/yacc.c: Likewise.
- * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
-
- * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.

- SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.

-
- * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
- them with auto vars.
- Switch to new escape scheme, where @ is the escape character uniformly.
- Abort if a stray escape character is found. Avoid unbounded input
- buffer when parsing non-escaped text.
-
- * tests/input.at (Torturing the Scanner): Add tests that @oline@,
- __oline__, #output, $@, and @{ do not have unintended meanings.
-
-2002-11-09 Paul Eggert <eggert@twinsun.com>
-
- Fix the test failure due to GCC warnings described in
- <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.

- evaluate to 0 if it's impossible for NINF to be in the respective
- table.
- (yygetLRActions, yyrecoverParseError): Use them.
-
- * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
- counted in the token inserted at end of file. Now takes
- location_t *, not location_t, so that the location can be
- adjusted. All uses changed.
-
- * tests/regression.at (Invalid inputs): Adjust wording in
- diagnostic to match the new behavior.
-
- * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
- AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
- AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
- abort ();'. This reduces the runtime of the "Many lookaheads"
- test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
- GCC 3.2.
-
-2002-11-07 Paul Eggert <eggert@twinsun.com>
-
- * src/parse-gram.y (CHARACTER): Remove unused token.
- All uses removed.
-
- * src/scan-gram.l: Remove stack option. We no longer use the
- stack, since the stack was never deeper than 1; instead, use the
- new auto var c_context to record the stacked value.
-
- Remove nounput option. At an unexpected end of file, we now unput
- the minimal input necessary to end cleanly; this simplifies the
- code.
-
- Avoid unbounded token sizes where this is easy.
-
- (unexpected_end_of_file): New function.
- Use it to systematize the error message on unexpected EOF.
- (last-string): Now auto, not static.
- (YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
- (scanner_last_string_free): Remove; not used.
- (percent_percent_count): Move decl to just before use.

- not the (never otherwised-used) CHARACTER.

-
-2002-10-24 Akim Demaille <akim@epita.fr>

-
- * data/README: New.
-
-2002-10-21 Paul Eggert <eggert@twinsun.com>

-
- * src/getargs.c (getargs): When there are too few operands, report

-
- Let nondeterministic skeletons be usable with deterministic
- tables.
-
- With the patch, GAWK compiled by GCC without -O2 passes its test
- suite using a GLR parser driven by LALR tables. It fails with -O2
- because `struct stat' gives two different answers on my machine:
- 88 (definition of an auto var) and later 96 (memset on this var).
- Hence the stack is badly corrumpted. The headers inclusion is to
- blame: if I move the awk.h inclusion before GLR's system header
- inclusion, the two struct stat have the same size.
-
- * src/tables.c (pack_table): Always create conflict_table.
- (token_actions): Always create conflict_list.

- (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
- (which was a bug: it should have been YYTABEL_NINF, and yet it was
- not satisfying as we could compare an YYACTION computed from
- YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
- only value for error actions.
- (yyreportParseError): In verbose parse error messages, don't issue
- `error' in the list of expected tokens.
- * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the

- Fix problem reported by Henrik Grubbstroem in
- <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>:
- "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
- because the Bison parser reads the second action before reducing
- the first one.
- * src/scan-gram.l (rule_length): New static var.
- Use it to keep track of the rule length in the scanner, since
- we can't expect the parser to be in lock-step sync with the scanner.
- (handle_action_dollar, handle_action_at): Use this var.
- * tests/actions.at (Exotic Dollars): Test for the problem.

-2002-01-20 Marc Autret <marc@gnu.org>
-
- * src/files.c (compute_output_file_names): Fix
-
-2002-01-20 Marc Autret <marc@gnu.org>
-
- * tests/output.at: New test.
- * src/files.c (compute_base_names): Don't map extensions when
- the YACC flag is set, use defaults.
- Reported by Evgeny Stambulchik.
-
-2002-01-20 Marc Autret <marc@gnu.org>
-
- * src/system.h: Need to define __attribute__ away for non-GCC
- compilers as well (i.e., the vendor C compiler).
- Suggested by Albert Chin-A-Young.
-
-2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
-
- * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
- canonical definition.
- * src/system.h: Use the canonical definition for PARAMS (avoids
- a conflict with the macro from lib/hash.h).
-
-2002-01-11 Akim Demaille <akim@epita.fr>
-
- * configure.in: Use AC_FUNC_STRNLEN.
- Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
-
-2002-01-09 Akim Demaille <akim@epita.fr>
-
- * src/files.c, src/files.h (output_infix): New.
- (tab_extension): Remove.
- (compute_base_names): Compute the former, drop the latter.
- * src/output.c (prepare): Insert the muscles `output-infix', and
- `output-suffix'.

- (section.yacc): Remove.
- (prefix): Remove too.
- * src/scan-skel.l: Adjust.
- * src/bison.simple, src/bison.hairy: Adjust.
-
-2002-01-09 Akim Demaille <akim@epita.fr>
-

- * src/Makefile.am (CFLAGS): Pass it.
- * tests/atlocal.in (CFLAGS): Idem.
- * src/files.c: Fix a few warnings.
- (get_extension_index): Remove, unused.
-
-2002-01-08 Akim Demaille <akim@epita.fr>
-
- * src/getargs.c (AS_FILE_NAME): New.
- (getargs): Use it to convert DOSish file names.
- * src/files.c (base_name): Rename as full_base_name to avoid
- clashes with `base_name ()'.
- (filename_split): New.
- (compute_base_names): N-th rewrite, using filename_split.
-
-2002-01-08 Akim Demaille <akim@epita.fr>
-
- * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
- New, stolen from the Fileutils 4.1.
- * lib/Makefile.am (libbison_a_SOURCES): Adjust.
- * configure.in: Check for the presence of memrchr, and of its
- prototype.
-
-2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
-
- * lib/hash.h (__P): Added definition for this macro.
- * src/Makefile.am: Add parse-skel.c and scan-skel.c to
- BUILT_SOURCES, to ensure they are generated first.
- * src/parse-skel.y: Use YYERROR_VERBOSE instead of
- %error-verbose to allow bootstrapping with bison 1.30x.
-
-2002-01-06 Akim Demaille <akim@epita.fr>
-
- * src/reader.c (parse_braces): Don't fetch the next char, the
- convention is to fetch on entry.
- * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
- 'switch' without a following semicolon.
- * tests/regression.at (braces parsing): New.
-
-2002-01-06 Akim Demaille <akim@epita.fr>
-
- Bison is dead wrong in its RR conflict reports.
-
- * tests/torture.at (GNU Cim Grammar): New.
- * src/conflicts.c (count_rr_conflicts): Fix.
-
-2002-01-06 Akim Demaille <akim@epita.fr>
-
- Creating package.m4 from configure.ac causes too many problems.
-
- * tests/Makefile.am (package.m4): Create it by hand,
- AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
-
-2002-01-06 Akim Demaille <akim@epita.fr>
-
- * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
- skeleton.h.
-
-2002-01-04 Paul Eggert <eggert@twinsun.com>
-
- * doc/bison.texinfo (Debugging):

- Also, s/cstdio.h/cstdio/.
-
-2002-01-03 Akim Demaille <akim@epita.fr>
-
- * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
-
-2002-01-03 Akim Demaille <akim@epita.fr>
-
- * src/parse-skel.y (process_skeleton): Don't bind the parser's
- tracing code to --trace, wait for a better --trace option, with
- args.
-
-2002-01-03 Akim Demaille <akim@epita.fr>
-
- * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
- The ISO C++ standard is extremely clear about it: stderr is
- considered a macro, not a regular symbol (see table 94 `Header
- <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
- Therefore std:: does not apply to it. It still does with fprintf.
- Also, s/cstdio.h/cstdio/.
-
-2002-01-03 Akim Demaille <akim@epita.fr>
-
- * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
- for non system headers.
-
-2002-01-02 Akim Demaille <akim@epita.fr>
-
- Equip the skeleton chain with location tracking, runtime trace,
- pure parser and scanner.
-
- * src/parse-skel.y: Request a pure parser, locations, and prefix
- renaming.
- (%union): Having several members with the same type does not help
- type mismatches, simplify.
- (YYPRINT, yyprint): New.
- (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
- (skel_error): this.
- Handle locations.
- * src/scan-skel.l: Adjust to these changes.
- * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
- (LOCATION_PRINT, skel_control_t): New.
-
-2001-12-30 Akim Demaille <akim@epita.fr>
-
- * src/parse-skel.y: Get rid of the shift/reduce conflict:
- replace `gb' with BLANKS.
- * src/scan-skel.l: Adjust.
-
-2001-12-30 Akim Demaille <akim@epita.fr>
-
- * src/system.h: We don't need nor want bcopy.
- Throw away MS-DOS crap: we don't need getpid.
- * configure.in: We don't need strndup. It was even causing
- problems: because Flex includes the headers *before* us,
- _GNU_SOURCE is not defined by config.h, and therefore strndup was
- not visible.
- * lib/xstrndup.c: New.
- * src/scan-skel.l: Use it.
- Be sure to initialize yylval.muscle member when scanning a MUSCLE.
- * src/parse-skel.y: Use %directives instead of #defines.
-
-2001-12-30 Akim Demaille <akim@epita.fr>
-
- * src/skeleton.h: New.
- * src/output.c (output_parser, output_master_parser): Remove, dead
- code.
- * src/output.h (get_lines_number, actions_output, guards_output)
- (token_definitions_output): Prototype them.
- * src/parse-skel.y: Add the license notice.
- Include output.h and skeleton.h.
- (process_skeleton): Returns void, and takes a single parameter.
- * src/scan-skel.l: Add the license notice.
- Include skeleton.h.
- Don't use %option yylineno: it seems that then Flex imagines
- REJECT has been used, and therefore it won't reallocate its
- buffers (which makes no other sense to me than a bug). It results
- in warnings for `unused: yy_flex_realloc'.
-
-2001-12-30 Robert Anisko <robert.anisko@epita.fr>
-
- * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
- (MUSCLE_INSERT_PREFIX): ...to there.
- * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
- (MUSCLE_INSERT_PREFIX): Move from here...
-
- * src/bison.hairy: Add a section directive. Put braces around muscle
- names. This parser skeleton is still broken, but Bison should not
- choke on a bad muscle 'syntax'.
- * src/bison.simple: Add a section directive. Put braces around muscle
- names.
-
- * src/files.h (strsuffix, stringappend): Add declarations.
- (tab_extension): Add declaration.
- (short_base_name): Add declaration.

- names.
- (short_base_name): No longer static.
-
- * src/output.c (output_skeleton): New.
- (output): Disable call to output_master_parser, and give a try to
- a new skeleton handling system.
- (guards_output, actions_output): No longer static.
- (token_definitions_output, get_lines_number): No longer static.
-
- * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
-
- * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
- parse-skel.y.
-
- * src/parse-skel.y: New file.
- * src/scan-skel.l: New file.
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- %name-prefix is broken.
-
- * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
- Adjust all dependencies.
- * tests/headers.at (export YYLTYPE): Strengthen this test: use
- %name-prefix.
-
- Renaming yylval but not yylloc is not consistent. Now we do.
-
- * src/bison.simple: Prefix yylloc if used.
- * doc/bison.texinfo (Decl Summary): Document that.
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- * doc/bison.texinfo: Promote `%long-directive' over
- `%long_directive'.
- Remove all references to fixed-output-files, yacc is enough.
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
- user prologue. These are defaults.
- * tests/actions.at (Mid-rule actions): Make sure the user can
- define YYDEBUG and YYERROR_VERBOSE.
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- * src/output.c (header_output): Don't forget to export YYLTYPE and
- yylloc.
- * tests/headers.at (export YYLTYPE): New, make sure it does.
- * tests/regression.at (%union and --defines, Invalid CPP headers):
- Move to...
- * tests/headers.at: here.
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- * tests/actions.at (Mid-rule actions): Output on a single line
- instead of several.
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- * doc/bison.texinfo: Formatting changes.
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- Don't store the token defs in a muscle, just be ready to output it
- on command. Now possible via `symbols'. Fixes a memory leak.
-
- * src/output.c (token_definitions_output): New.
- (output_parser, header_output): Use it.
- * src/reader.c (symbols_save): Remove.
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- * src/bison.simple: Do not provide a default for YYSTYPE and
- YYLTYPE before the user's prologue. Otherwise it's hardly... a
- default.
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- Mid-rule actions are simply... ignored!
-
- * src/reader.c (readgram): Be sure to attach mid-rule actions to
- the empty-rule associated to the dummy symbol, not to the host
- rule.
- * tests/actions.at (Mid-rule actions): New.
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- Memory leak.

- * src/reader.c (reader): Free grammar.
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- Memory leak.
-
- * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
- since it allocates it for each state, although only one is needed.
- (allocate_storage): Do it here.
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- * src/options.h, src/options.c (create_long_option_table): Rename
- as...
- (long_option_table_new): this, with a clearer prototype.
- (percent_table): Remove, unused,
- * src/getargs.c (getargs): Adjust.
-
-2001-12-29 Akim Demaille <akim@epita.fr>

- as states.
-
-2001-12-29 Akim Demaille <akim@epita.fr>

- as rules.
-
-2001-12-29 Akim Demaille <akim@epita.fr>

- ago.
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- * src/reader.c, src/reader.h (user_toknums): Remove.
- Adjust all users to use symbols[i]->user_token_number.
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- * src/gram.c, src/gram.h (sprec, sassoc): Remove.

- Use symbols[i]->tag instead of tags[i].
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
- In addition, put a comment in there, to replace...
- * tests/regression.at (%union and C comments): Remove.
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- * tests/regression.at (Web2c Actions): Blindly move the actual
- output as expected output. The contents *seem* right to me, but I
- can't pretend reading perfectly parser tables... Nonetheless, all
- the other tests pass correctly, the table look OK, even though the
- presence of `$axiom' is to be noted: AFAICS it is useless (but
- harmless).
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- * src/reader.c (readgram): Don't add the rule 0 if there were no
- rules read. In other words, add it _after_ having performed
- grammar sanity checks.
- Fixes the `tests/regression.at (Invalid input: 1)' Failure.
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
- visible, and some states have now a different number.
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- * src/reader.c (readgram): Bind the initial rule's lineno to that
- of the first rule.
- * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
- (Solved SR Conflicts): Adjust rule 0's line number.
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- Fix the `GAWK Grammar' failure.
-
- * src/LR0.c (final_state): Initialize to -1 so that we do compute
- the reductions of the first state which was mistakenly confused
- with the final state because precisely final_state was initialized
- to 0.
- * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
- now noticed by Bison.
- * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
- have a reduction on $default.
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-

-
- * src/lalr.c (lookaheads_print): New.
- (lalr): Call it when --trace-flag.
- * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
- are dumped.
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',

- * src/reduce.c (dump_grammar, useful_production, reduce_output)
- (useful_production, useless_nonterminals): Likewise.
- (reduce_grammar_tables): Likewise, plus update nritems.
- * src/nullable.c (set_nullable): Likewise.
- * src/lalr.c (build_relations): Likewise.
- * tests/sets.at (Nullable): Adjust.
- Fortunately, now, the $axiom is no longer nullable.
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- * src/LR0.c (generate_states): Use nritems, not nitems, nor using
- the 0-sentinel.
- * src/gram.c (ritem_longest_rhs): Likewise.
- * src/reduce.c (nonterminals_reduce): Likewise.
- * src/print_graph.c (print_graph): Likewise.

-
- * src/output.c: Comment changes.
-
-2001-12-27 Paul Eggert <eggert@twinsun.com>
-
- * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
- cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
- Sparc, as they were causing more porting problems than the
- (minor) performance improvement was worth.
-
- Also, catch up with 1.31's YYSTD.
-
-2001-12-27 Akim Demaille <akim@epita.fr>
-
- * src/output.c (output_gram): Rely on nritems, not the
- 0-sentinel. See below.
- Use -1 as separator, not 0.
- * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
- Rely on -1 as separator in yyrhs, instead of 0.
- * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
- twice `Now at end of input', therefore there are two lines less to
- expect.
-
-2001-12-27 Akim Demaille <akim@epita.fr>
-
- * tests/regression.at (Unresolved SR Conflicts):
- (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
- below.
-
-2001-12-27 Akim Demaille <akim@epita.fr>
-

- is reached by eoftoken.
- (insert_start_shifting_state, insert_eof_shifting_state)
- (insert_accepting_state, augment_automaton): Remove, since now
- these states are automatically computed from the initial state.
- (generate_states): Adjust.
- * src/print.c: When reporting a rule number to the user, substract
- 1, so that the axiom rule is rule 0, and the first user rule is 1.
- * src/reduce.c: Likewise.
- * src/print_graph.c (print_core): For the time being, just as for
- the report, depend upon --trace-flags to dump the full set of
- items.
- * src/reader.c (readgram): Once the grammar read, insert the rule
- 0: `$axiom: START-SYMBOL $'.
- * tests/set.at: Adjust: rule 0 is now displayed, and since the
- number of the states has changed (the final state is no longer
- necessarily the last), catch up.
-
-2001-12-27 Akim Demaille <akim@epita.fr>
-
- Try to make the use of the eoftoken valid. Given that its value
- is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
- is used instead of > 0 where appropriate, (ii), depend upon nritems
- instead of the 0-sentinel.
-
- * src/gram.h, src/gram.c (nritems): New.
- Expected to be duplication of nitems, but for the time being...
- * src/reader.c (packgram): Assert nritems and nitems are equal.
- * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
- * src/closure.c (print_closure, print_fderives): Likewise.

- reductions, then output the report anyway if requested, then die.
- * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
- * src/reader.c (eoftoken): New.
- (parse_token_decl): If the token being defined has value `0', it
- is the eoftoken.
- (packsymbols): No longer hack `tags' to insert `$' by hand.
- Be sure to preserve the value of the eoftoken.
- (reader): Make sure eoftoken is defined.
- Initialize nsyms to 0: now eoftoken is created just like the others.
- * src/print.c (print_grammar): Don't special case the eof token.
- * src/regression.at: Adjust: `$' has value 0, not -1, which was a
- lie anyway, albeit pleasant.
- * tests/calc.at: Exercise error messages with eoftoken.
- Change the grammar so that empty input is invalid.
- Adjust expectations.
- When yyungeting, be sure to use a valid yylloc: use last_yylloc.

-
- * src/state.h, src/state.c (reductions_new): New.
