Tim Northover 984ee65445 X86: elide comparisons after cmpxchg instructions. ... The C++ and C semantics of the compare_and_swap operations actually require us to return a boolean "success" value. In LLVM terms this means a second comparison of the output of "cmpxchg" against the input desired value. However, x86's "cmpxchg" instruction sets all flags for the comparison formed, so we can skip any secondary comparison. (N.b. this isn't true for cmpxchg8b/16b, which only set ZF). rdar://problem/13201607 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@210523 91177308-0d34-0410-b5e6-96231b3b80d8		2014-06-10 10:49:07 +00:00
