Dan Gohman 62c939d7d5 Mark x86's V_SET0 and V_SETALLONES with isSimpleLoad, and teach X86's ... foldMemoryOperand how to "fold" them, by converting them into constant-pool loads. When they aren't folded, they use xorps/cmpeqd, but for example when register pressure is high, they may now be folded as memory operands, which reduces register pressure. Also, mark V_SET0 isAsCheapAsAMove so that two-address-elimination will remat it instead of copying zeros around (V_SETALLONES was already marked). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60461 91177308-0d34-0410-b5e6-96231b3b80d8		2008-12-03 05:21:24 +00:00
