Evan Cheng 9568e5c3c3 Teach dag combine to match halfword byteswap patterns. ... 1. (((x) & 0xFF00) >> 8) | (((x) & 0x00FF) << 8) => (bswap x) >> 16 2. ((x&0xff)<<8)|((x&0xff00)>>8)|((x&0xff000000)>>8)|((x&0x00ff0000)<<8)) => (rotl (bswap x) 16) This allows us to eliminate most of the def : Pat patterns for ARM rev16 revsh instructions. It catches many more cases for ARM and x86. rdar://9609108 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133503 91177308-0d34-0410-b5e6-96231b3b80d8		2011-06-21 06:01:08 +00:00
