Daniel Jasper bbaf4fd14c During PHI elimination, split critical edges that move copies out of loops. ... This prevents the behavior observed in llvm.org/PR22369. I am not sure whether I am reading the code correctly, but the early exit based on isLiveOutPastPHIs() seems to make the wrong assumption that RegisterCoalescer won't be able to coalesce those copies later. This change hides the new behavior behind -no-phi-elim-live-out-early-exit as it currently breaks four tests: * Assertion in: CodeGen/Hexagon/hwloop-cleanup.ll * Worse code in: CodeGen/X86/coalescer-commute4.ll CodeGen/X86/phys_subreg_coalesce-2.ll CodeGen/X86/zlib-longest-match.ll The root cause here seems to be that the heuristic that determines the visitation order in RegisterCoalescer gets less lucky. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@231064 91177308-0d34-0410-b5e6-96231b3b80d8		2015-03-03 10:23:11 +00:00
