Chandler Carruth fe05f61e5d [x86] Add handling for splat-like widenings of v16i8 shuffles. ... These show up really frequently, not the least with actual splats. =] We lowered these quite badly before. The new code path tries to widen i8 shuffles to i16 shuffles in a splat-like way. There are still some inefficiencies in our i16 splat logic though, so we aren't really done here. Also, for certain patterns (bit of a gather-and-splat) we still generate pretty silly code, and I've left a fixme for addressing it. However, I'm not actually worried about this code pattern as much. The old shuffle lowering generates a 29 instruction monstrosity for it that should execute much more slowly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211974 91177308-0d34-0410-b5e6-96231b3b80d8		2014-06-28 05:16:40 +00:00
