[PATCH] D28489: [CodeGen] Generalize MacroFusion for any instructions pair

[Matthias Braun via Phabricator via llvm-commits]

MatzeB added a comment.

Have you checked the effects for compiletime? This will check every edge in the schedule graph, I wonder if we shouldn't rather delegate the whole search to the target so it can restrict this to the actually interesting instructions instead of checking every edge.
