Richard Sandiford 83a0b6abd0 [SystemZ] Optimize comparisons with truncated extended loads ... If the extension of a loaded value is compared against zero and used in other arithmetic, InstCombine will change the comparison to use the unextended load. It's also possible that the comparison could be against the unextended load from the outset. In DAG form this becomes a truncation of an extending load. We want to strip the truncation if possible so that we can use load-and-test instructions. llvm-svn: 197804		2013-12-20 11:56:02 +00:00
