[PATCH] D80801: [DAGCombiner] allow more folding of fadd + fmul into fma

[Scott Manley via Phabricator via llvm-commits]

rscottmanley added a comment.

Wouldn't it be better to choose between what you have here fmadd(a,b,fma(c,d,n)) and a*b + fmadd(c,d,n) for targets that perform worse with FMA chains?
