[PATCH] D111325: RFC: Use data deps for schedule barrier; Only look at data deps in MacroFusion

[Dave Green via Phabricator via llvm-commits]

dmgreen added a comment.

Unfortunately the benchmarking I have downstream doesn't suggest this is a great idea. Nothing gets a lot worse, but a lot of things get a little worse.

These are mostly for small in-order cores like the cortex-m55. I haven't looked deeply into why. There is a chance our downstream schedules are just getting unlucky.
