Chandler Carruth 5b0b023a64 [SDAG] Actually check for a non-constant splat and clarify comments ... around the handling of UNDEF lanes in boolean vector content analysis. The code before my changes here also failed to check for non-constant splats in a buildvector. I have no idea how to trigger this, I just spotted by inspection when trying to understand the code. It seems extremely unlikely to be worth the trouble to teach the only caller of this code (DAG combining setcc patterns) how to cleverly handle undef lanes, so I've just commented more thoroughly that we're giving up there. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@212515 91177308-0d34-0410-b5e6-96231b3b80d8		2014-07-08 07:44:15 +00:00
