[LLVMdev] Question about FMA formation

> Why not just form them via a fast IR level pass and just have patterns match in fast isel instead of trying to form code? Or are we saying the same thing? (Your words of "fast isel spot"ting and "form better code" caused me to think you mean to do optimizations within the fast isel pass).
