New Revision: 298765
URL: http://llvm.org/viewvc/llvm-project?rev=298765&view=rev
Log:
Add the _CALL_LINUX preprocessor define for ppc linux platforms.
This typically is only for a new enough linker (bfd >= 2.16.2 or gold), but
our ppc suppport post-dates this and it should work on all linux platforms. It
is guaranteed to work on all elfv2 platforms.
