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 llvm-svn: 133503

ops. This is a rewrite of the IV simplification algorithm used by -disable-iv-rewrite. To avoid perturbing the default mode, I temporarily split the driver and created SimplifyIVUsersNoRewrite. The idea is to avoid doing opcode/pattern matching inside IndVarSimplify. SCEV already does it. We want to optimize with the full generality of SCEV, but optimize def-use chains top down on-demand rather than rewriting the entire expression bottom-up. This was easy to do for operations that SCEV can prove are identity function. So we're now eliminating bitmasks and zero extends this way. A result of this rewrite is that indvars -disable-iv-rewrite no longer requires IVUsers. llvm-svn: 133502
