* Avoid folding loads that are unsafe to move.Jakob Stoklund Olesen2012-07-202-0/+156
| | | | | | | | | | 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

| | | | | | | | | | | 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
* Split loop exiting edges more aggressively.Jakob Stoklund Olesen2012-07-202-13/+86
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
