Manman Ren 2d4215f759 X86: Fix optimizeCompare to correctly check safe condition. ... It is safe if EFLAGS is killed or re-defined. When we are done with the basic block, check whether EFLAGS is live-out. Do not optimize away cmp if EFLAGS is live-out. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159888 91177308-0d34-0410-b5e6-96231b3b80d8		2012-07-07 03:34:46 +00:00
