Chandler Carruth bf21d40070 [x86] Teach the new vector shuffle lowering to widen floating point ... elements as well as integer elements in order to form simpler shuffle patterns. This is the primary reason why we were failing to match some of the 2-and-2 floating point shuffles such as PR21140. Even after fixing this we need to support some extra patterns in the backend in order to match the resulting X86ISD::UNPCKL nodes into the correct instructions. This commit should fix PR21140 and includes more comprehensive testing of insertion patterns in v4 shuffles. Not all of the added tests are beautiful. For example, we don't have clever instructions to insert-via-load in the integer domain. There are also some places where we aren't sufficiently cunning with our use of movq and movd, but that's future work. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@218911 91177308-0d34-0410-b5e6-96231b3b80d8		2014-10-02 21:37:14 +00:00
