------------------------------------------------------------------------ r242539 | rnk | 2015-07-17 09:23:05 -0700 (Fri, 17 Jul 2015) | 14 lines compiler-rt: add support for mingw-w64 in builtins The is so that we can avoid using libgcc and use compiler-rt with mingw-w64. Related driver patch http://reviews.llvm.org/D11077 I have tested this with mingw-w64 and everything seems to be in order. I also sent this patch to the mingw-w64 mailing list for them to look at.
