[PATCH] D152059: [AVR] Replace shift-to-loop IR pass with common shift code

[Ayke via Phabricator via llvm-commits]

aykevl added a comment.

IIRC for the code size reductions to really work, you also need to enable sub register liveness (that's the other patch in my branch). I don't remember how big of a difference it made. It's not needed for correctness though.
