[LLVMdev] [RFC] Extend LLVM IR to express "fast-math" at a per-instruction level
Introduction --- LLVM IR currently does not have any support for specifying fine-grained control over relaxing floating point requirements for the optimizer. The below is a proposal to extend floating point IR instructions to support a number of flags that a creator of IR can use to allow for greater optimizations when desired. Such changes are sometimes referred to as fast-math, but this
