Condition code in DAGCombiner::visitFADDForFMACombine?
For this code:
%20 = fmul reassoc nnan arcp contract float %15, %19
%21 = fadd nnan arcp float %20, -1.000000e+00
This does not result in fused multiply-add.
it seems like the logic to contact the fmul from the fadd is different than
whether to decide to contract the fadd. I would think the logic would be
the same for each instruction in the pair.
