[PATCH] D110561: [AArch64] Alter arith-cbz-fusion to fuse between pairs register instructions

[Matthias Braun via Phabricator via llvm-commits]

MatzeB added a comment.

I haven't worked with this code for a while, but isn't this function only invoked when there is an edge in the schedule graph between the two nodes anyway so they must be writing/reading the same register and you wouldn't need the extra check you are adding here?
