Andrea Di Biagio 124ce3ab36 [DAGCombiner] Fix a crash caused by a missing check for legal type when trying to fold shuffles. ... Verify that DAGCombiner does not crash when trying to fold a pair of shuffles according to rule (added at r212539): (shuffle (shuffle A, Undef, M0), Undef, M1) -> (shuffle A, Undef, M2) The DAGCombiner avoids folding shuffles if the resulting shuffle dag node is not legal for the target. That means, the resulting shuffle must have legal type and legal mask. Before, the DAGCombiner only called method 'TargetLowering::isShuffleMaskLegal' to check if it was "safe" to fold according to the above-mentioned rule. However, this caused a crash in the x86 backend since method 'isShuffleMaskLegal' always expects to be called on a legal vector type. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@212915 91177308-0d34-0410-b5e6-96231b3b80d8		2014-07-13 21:02:14 +00:00
