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.

In case of template specialization, do not try to delay emitting debug info for concrete type in -flimit-debug-info mode. This fixes some of the failures from bs15503.exp tests in gdb testsuite. llvm-svn: 143227 2011-10-28 21:12:13 +00:00
