Chandler Carruth f159de96bd [x86] Add a really preposterous number of patterns for matching all of ... the various ways in which blends can be used to do vector element insertion for lowering with the scalar math instruction forms that effectively re-blend with the high elements after performing the operation. This then allows me to bail on the element insertion lowering path when we have SSE4.1 and are going to be doing a normal blend, which in turn restores the last of the blends lost from the new vector shuffle lowering when I got it to prioritize insertion in other cases (for example when we don't *have* a blend instruction). Without the patterns, using blends here would have regressed sse-scalar-fp-arith.ll *completely* with the new vector shuffle lowering. For completeness, I've added RUN-lines with the new lowering here. This is somewhat superfluous as I'm about to flip the default, but hey, it shows that this actually significantly changed behavior. The patterns I've added are just ridiculously repetative. Suggestions on making them better very much welcome. In particular, handling the commuted form of the v2f64 patterns is somewhat obnoxious. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@219033 91177308-0d34-0410-b5e6-96231b3b80d8		2014-10-03 22:43:17 +00:00
