[PATCH] D98335: [AVR] Refactor 8-bit & 16-bit shifts

[Ayke via Phabricator via llvm-commits]

This looks indeed a lot cleaner! I'm glad the blog post was useful :)

Ideally all these instructions would be expanded before register allocation (as described in my blog post), but sadly that doesn't seem to be possible with the current design of the AVR backend. Maybe it becomes possible in the future with GlobalISel.
