Andrea Di Biagio d25126faae [InstCombine] Fix regression introduced at r227197. ... This patch fixes a problem I accidentally introduced in an instruction combine on select instructions added at r227197. That revision taught the instruction combiner how to fold a cttz/ctlz followed by a icmp plus select into a single cttz/ctlz with flag 'is_zero_undef' cleared. However, the new rule added at r227197 would have produced wrong results in the case where a cttz/ctlz with flag 'is_zero_undef' cleared was follwed by a zero-extend or truncate. In that case, the folded instruction would have been inserted in a wrong location thus leaving the CFG in an inconsistent state. This patch fixes the problem and add two reproducible test cases to existing test 'InstCombine/select-cmp-cttz-ctlz.ll'. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@229124 91177308-0d34-0410-b5e6-96231b3b80d8		2015-02-13 16:33:34 +00:00
