New Revision: 43937
URL: http://llvm.org/viewvc/llvm-project?rev=43937&view=rev
Log:
Fix fallout from recent commits. This fixes PR1785
Folks, when syncing to Apple gcc, please, do remember, that some files
are nullified in the gcc/config directory (mostly for targets Apple doesn't care),
don't propagate this to llvm-gcc. This stuff is hard to catch, because it doesn't
lead to any errors during gcc compilation, only resulting binaries are broken.
