[PATCH] D143143: [AArch64] Reassociate sub(x, add(m1, m2)) to sub(sub(x, m1), m2)

[Sjoerd Meijer via Phabricator via llvm-commits]

SjoerdMeijer added a comment.

The patch looks good to me, but I was just wondering if another approach would be to just match the `sub(x, add(m1, m2)).` pattern as mls, or is this easier/better?
