Hal Finkel 9ae5b7a40a [PowerPC] Mark zext of a small scalar load as free ... This initial implementation of PPCTargetLowering::isZExtFree marks as free zexts of small scalar loads (that are not sign-extending). This callback is used by SelectionDAGBuilder's RegsForValue::getCopyToRegs, and thus to determine whether a zext or an anyext is used to lower illegally-typed PHIs. Because later truncates of zero-extended values are nops, this allows for the elimination of later unnecessary truncations. Fixes the initial complaint associated with PR22120. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@225584 91177308-0d34-0410-b5e6-96231b3b80d8		2015-01-10 08:21:59 +00:00
