New Revision: 47213
URL: http://llvm.org/viewvc/llvm-project?rev=47213&view=rev
Log:
I cannot find a libgcc function for this builtin. Therefor expanding it to a
noop (which is how it use to be treated). If someone who knows the x86 backend
better than me could tell me how to get a lock prefix on an instruction, that
would be nice to complete x86 support.
