Evan Cheng 089751535d Avoiding overly aggressive latency scheduling. If the two nodes share an ... operand and one of them has a single use that is a live out copy, favor the one that is live out. Otherwise it will be difficult to eliminate the copy if the instruction is a loop induction variable update. e.g. BB: sub r1, r3, #1 str r0, [r2, r3] mov r3, r1 cmp bne BB => BB: str r0, [r2, r3] sub r3, r3, #1 cmp bne BB This fixed the recent 256.bzip2 regression. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117675 91177308-0d34-0410-b5e6-96231b3b80d8		2010-10-29 18:09:28 +00:00
