Rename clang to clang-cc. Tests and drivers updated, still need to shuffle dirs. llvm-svn: 67602 2009-03-24 10:24:46 +08:00			`// RUN: clang-cc -fsyntax-only -verify -pedantic %s`
- Implement __block. - Replace FIXME in Preprocessor::HandleIdentifier() with a check that avoids diagnosing extension tokens that originate from macro definitions. llvm-svn: 55639 2008-09-03 02:50:17 +08:00
