* | Add support for fast-math flags to the FCmp instruction. | James Molloy | 2015-07-10 | 1 | -0/+23 |
FCmp behaves a lot like a floating-point binary operator in many ways, and can benefit from fast-math information. Flags such as nsz and nnan can affect if this fcmp (in combination with a select) can be treated as a fminnum/fmaxnum operation. This adds backwards-compatible bitcode support, IR parsing and writing, LangRef changes and IRBuilder changes. I'll need to audit InstSimplify and InstCombine in a followup to find places where flags should be copied. llvm-svn: 241901 |
