Andrew Trick 2fabd464ae indvars -disable-iv-rewrite: Adds support for eliminating identity ... 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133502 91177308-0d34-0410-b5e6-96231b3b80d8		2011-06-21 03:22:38 +00:00
