[PATCH] D43409: [GISel]: Don't assert when constraining Registers which are uses if there's no regclass.

[Daniel Sanders via Phabricator via llvm-commits]

dsanders added a comment.

Hmm, I'm a bit reluctant to make this conditional on whether it's a use/def. Doing that feels like a bigger relaxation on the assertion than should be needed. Is it possible to make it conditional on whether the constraint is specified to be `unknown`?
