Hal Finkel 3ab10c1918 [PowerPC] Remove zexts after i32 ctlz ... The 64-bit semantics of cntlzw are not special, the 32-bit population count is stored as a 64-bit value in the range [0,32]. As a result, it is always zero extended, and it can be added to the PPCISelDAGToDAG peephole optimization as a frontier instruction for the removal of unnecessary zero extensions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@225192 91177308-0d34-0410-b5e6-96231b3b80d8		2015-01-05 18:52:29 +00:00
