Remove the -cxx-abi command-line flag. This makes the C++ ABI depend entirely on the target: MS ABI for -win32 triples, Itanium otherwise. It's no longer possible to do weird combinations. To be able to run a test with a specific ABI without constraining it to a specific triple, new substitutions are added to lit: %itanium_abi_triple and %ms_abi_triple can be used to get the current target triple adjusted to the desired ABI. For example, if the test suite is running with the i686-pc-win32 target, %itanium_abi_triple will expand to i686-pc-mingw32.

Fix our handling of #pragma GCC visibility. Now the lexer just produces a token and the parser is the one responsible for activating it. This fixes problem like the one pr11797 where the lexer and the parser were not in sync. This also let us be more strict on where in the file we accept these pragmas. llvm-svn: 149014 2012-01-26 10:02:57 +08:00

CHECK-LABEL-ify some code gen tests to improve diagnostic experience when tests fail. llvm-svn: 188447 2013-08-15 14:47:53 +08:00			`// CHECK-LABEL: define void @_Z3foov()`
