[PATCH] D156538: [AArch64] Try to combine FMUL with FDIV

[Dave Green via Phabricator via llvm-commits]

dmgreen added a comment.

Oh I see, I hadn't spotted performFDivCombine. It was the scalar patterns I was thinking about, via IntegerToFP and fixedpoint_f32_i32 and SelectCVTFixedPosOperand.

Does it make sense to keep them selection fdiv, or should they always just match fmul? It would seem we only need one, and fmul is more canonical.
