* Remove the -cxx-abi command-line flag.Hans Wennborg2014-01-141-1/+1
| | | | | | | | | | | | | | | 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.

* Switch to the new MingW ABI.Rafael Espindola2013-12-121-1/+1
| | | | | | | GCC 4.7 changed the MingW ABI. On the clang side this means that methods now have the thiscall calling convention by default. llvm-svn: 197164

* Be more careful in applying pragma weak. Fixes pr14974.Rafael Espindola2013-02-261-0/+31
GCC applies a pragma weak to a decl if it matches the mangled name. We used to apply if it matched the plain name. This patch is a compromise: we apply the pragma only if it matches the name and the decl has C language linkage. llvm-svn: 176110
