[LLVMdev] Documentation of fmuladd intrinsic
Out of curiosity, what is the use-case for isFMAFasterThanMulAndAdd? If a target declares that FMA is actually slower for a given type, why not just declare it as illegal for that type? Wouldn't that accomplish the same thing without another target hook? I feel like I'm missing something here. On Fri, Jan 11, 2013 at 2:40 PM, Hal Finkel <hfinkel at anl.gov> wrote: > -----
