Andrew Trick 340d78f4e7 PreRA scheduler should avoid cloning compares. ... Added canClobberReachingPhysRegUse() to handle a particular pattern in which a two-address instruction could be forced to interfere with EFLAGS, causing a compare to be unnecessarilly cloned. Fixes rdar://problem/5875261 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138924 91177308-0d34-0410-b5e6-96231b3b80d8		2011-09-01 00:54:31 +00:00
