[PATCH] D12887: [Machine Combiner] Refactor machine reassociation into a target-independent pass

[Chad Rosier via llvm-commits]

mcrosier added a comment.

The intent of this patch is to remove the redundant code from the PPC backend and to expose the generic parts so that other backends (e.g., AArch64) can use this machinery.  I've added Hal to assist/comment on the PPC changes, if he's interested.
