Andrea Di Biagio 3e5582cc15 [X86] Add target combine rule to select ADDSUB instructions from a build_vector ... This patch teaches the backend how to combine a build_vector that implements an 'addsub' between packed float vectors into a sequence of vector add and vector sub followed by a VSELECT. The new VSELECT is expected to be lowered into a BLENDI. At ISel stage, the sequence 'vector add + vector sub + BLENDI' is pattern-matched against ISel patterns added at r211427 to select 'addsub' instructions. Added three more ISel patterns for ADDSUB. Added test sse3-avx-addsub-2.ll to verify that we correctly emit 'addsub' instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211679 91177308-0d34-0410-b5e6-96231b3b80d8		2014-06-25 10:02:21 +00:00
