[PATCH] D119916: Add a machine function pass to convert binop(phi(constants), v) to phi(binop)

[Nikita Popov via Phabricator via llvm-commits]

nikic added a comment.

My first question here would be whether it is preferable to do this as a machine-pass, or as a backend IR pass (which runs post-LSR at least, possibly part of CGP). Do you have any thoughts about what the trade-offs between those two options would be?
