There is no purpose in using it for single-input shuffles as pshufd is just as fast and doesn't tie the two operands. This removes a substantial amount of wrong-domain blend operations in SSSE3 mode. It also completes the usage of PALIGNR for integer shuffles and addresses one of the test cases Quentin hit with the new vector shuffle lowering. There is still the question of whether and when to use this for floating point shuffles. It is faster than shufps or shufpd but in the integer domain. I don't yet really have a good heuristic here for when to use this instruction for floating point vectors. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@218038 91177308-0d34-0410-b5e6-96231b3b80d8
