2012-07-20Avoid folding loads that are unsafe to move.Jakob Stoklund Olesen
LiveRangeEdit::foldAsLoad() can eliminate a register by folding a load into its only use. Only do that when the load is safe to move, and it won't extend any live ranges. This fixes PR13414. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160575 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-20Fix a dangling StringRef bug in the auto upgrader. In one case, we resetChandler Carruth
CI's name, and then used the StringRef pointing at its old name. I'm fixing it by storing the name in a std::string, and hoisting the renaming logic to happen always. This is nicer anyways as it will allow the upgraded IR to have the same names as the input IR in more cases. Another bug found by AddressSanitizer. Woot. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160572 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-20Split loop exiting edges more aggressively.Jakob Stoklund Olesen
PHIElimination splits critical edges when it predicts it can resolve interference and eliminate copies. It doesn't split the edge if the interference wouldn't be resolved anyway because the phi-use register is live in the critical edge anyway. Teach PHIElimination to split loop exiting edges with interference, even if it wouldn't resolve the interference. This removes the necessary copies from the loop, which is still an improvement from injecting the copies into the loop. The test case demonstrates the improvement.
