* MultiTestRunner: Validate '&&' at the end of RUN lines.Daniel Dunbar2009-07-251-1/+1
| | | | | | | | | - This is just to normalize, these will go away soon hopefully. Added all the missing '&&'s that have crept in. :) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@77062 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | which tries to do better error recovery when it is "obvious" that an identifier is a mis-typed typename. In this case, we try to parse it as a typename instead of as the identifier in a declarator, which gives us several options for better error recovery and immediately makes diagnostics more useful. For example, we now produce: t.c:4:8: error: unknown type name 'foo_t' static foo_t a = 4; ^ instead of: t.c:4:14: error: invalid token after top level declarator static foo_t a = 4; ^ Also, since we now parse "a" correctly, we make a decl for it, preventing later uses of 'a' from emitting things like: t.c:12:20: error: use of undeclared identifier 'a' int bar() { return a + b; } ^ I'd really appreciate any scrutiny possible on this, it is a tricky area. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68911 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | accurate diagnostics. For test/Lexer/comments.c we now emit: int x = 000000080; /* expected-error {{invalid digit}} */ ^ constants.c:7:4: error: invalid digit '8' in octal constant 00080; /* expected-error {{invalid digit}} */ ^ The last line is due to an escaped newline. The full line looks like: int y = 0000\ 00080; /* expected-error {{invalid digit}} */ Previously, we emitted: constants.c:4:9: error: invalid digit '8' in octal constant int x = 000000080; /* expected-error {{invalid digit}} */ ^ constants.c:6:9: error: invalid digit '8' in octal constant int y = 0000\ ^ which isn't too bad, but the new way is better for the user, regardless of whether there is an escaped newline or not. All the other lexer-related diagnostics should switch over to using AdvanceToTokenCharacter where appropriate. Help wanted :).
