* Merging r311330:Hans Wennborg2017-08-232-0/+20

Summary: The crash occurs when the first token after a preamble is a macro expansion. Fixed by moving replayPreambleConditionalStack from Parser into Preprocessor. It is now called right after the predefines file is processed.

| | | | | | | | | | | | | | | | | | Summary: This patch prevents getCanonicalDecl returning nullptr in case it finds a canonical TemplateDeclaration with no attached TemplatedDecl. Found by running the indexer over a version of the standard library deep inside a template metaprogramming mess.

* [modules] Teach clang how to merge typedef over anonymous structs in C mode.Vassil Vassilev2017-07-011-1/+1
| | | | | | | | | | | In C mode clang fails to merge the textually included definition with the one imported from a module. The C lookup rules fail to find the imported definition because its linkage is internal in non C++ mode. This patch reinstates some of the ODR merging rules for typedefs of anonymous tags for languages other than C++.

* Driver must return non-zero code on errors in command lineSerge Pavlov2017-05-242-12/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is recommit of r302775, reverted in r302777 due to a fail in clang-tidy. Original mesage is below. Now if clang driver is given wrong arguments, in some cases it continues execution and returns zero code. This change fixes this behavior. The fix revealed some errors in clang test set. File test/Driver/gfortran.f90 added in r118203 checks forwarding gfortran flags to GCC. Now driver reports error on this file, because the option -working-directory implemented in clang differs from the option with the same name implemented in gfortran, in clang the option requires argument, in gfortran does not. In the file test/Driver/arm-darwin-builtin.c clang is called with options -fbuiltin-strcat and -fbuiltin-strcpy. These option were removed in r191435 and now clang reports error on this test. File arm-default-build-attributes.s uses option -verify, which is not supported by driver, it is cc1 option. Similarly, the file split-debug.h uses options -fmodules-embed-all-files and -fmodule-format=obj, which are not supported by driver. Other revealed errors are mainly mistypes.
