Nate Begeman b706d29f9c PR2957 ... ISD::VECTOR_SHUFFLE now stores an array of integers representing the shuffle mask internal to the node, rather than taking a BUILD_VECTOR of ConstantSDNodes as the shuffle mask. A value of -1 represents UNDEF. In addition to eliminating the creation of illegal BUILD_VECTORS just to represent shuffle masks, we are better about canonicalizing the shuffle mask, resulting in substantially better code for some classes of shuffles. A clean up of x86 shuffle code, and some canonicalizing in DAGCombiner is next. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@69952 91177308-0d34-0410-b5e6-96231b3b80d8		2009-04-24 03:42:54 +00:00
