[PATCH] D98564: [AArch64] Peephole rule to remove redundant cmp after cset.

[Dave Green via Phabricator via llvm-commits]

dmgreen added a comment.

I imagine that the cset; cmp from the fp16 tests is just a missing optimization in ISel, and there might be good reason to do so there if it helps simplify the graph.

But like you said, this does fit in with the other peepholing code. And if it helps both ISels, that is good.
