Rename clang to clang-cc. Tests and drivers updated, still need to shuffle dirs. llvm-svn: 67602 2009-03-24 02:24:46 +00:00			`// RUN: clang-cc %s -verify -fheinous-gnu-extensions`
introduce a new -fheinous-gnu-extensions flag that enables really really horrible extensions that are disabled by default but that can be accepted by -fheinous-gnu-extensions (but which always emit a warning when enabled). As our first instance of this, implement PR3788/PR3794, which allows non-lvalues in inline asms in contexts where lvalues are required. bleh. llvm-svn: 66910 2009-03-13 17:38:01 +00:00
