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.

Make sure to call AddOverriddenMethods for implicit copy assignment operators; it's rare, but possible, for the difference to be significant. llvm-svn: 90301 2009-12-02 14:59:20 +08:00

Tweak test to check for a bit more. llvm-svn: 90302 2009-12-02 15:04:32 +08:00			`// CHECK: define linkonce_odr {{.*}} @_ZN1DaSERKS_`
