Hal Finkel 5d5d1539cc [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. llvm-svn: 225584		2015-01-10 08:21:59 +00:00
