Sanjay Patel 342c3bcf11 [InstCombine] enhance vector demanded elements to look at a vector select condition operand ... I noticed that we were not back-propagating undef lanes to shuffle masks when we have a shuffle that reduces the vector width. This is part of investigating/solving PR38691: https://bugs.llvm.org/show_bug.cgi?id=38691 The DAG equivalent was proposed with: D51696 Differential Revision: https://reviews.llvm.org/D51433 llvm-svn: 341981		2018-09-11 18:49:00 +00:00
