[PATCH] D96015: [RegAllocFast] Handle case where operand of copy cannot be assigned.

[Quentin Colombet via Phabricator via llvm-commits]

qcolombet added a comment.

How was this test working before?

Again I am not very keen on this approach because technically we could have this problem with any instruction and:

1. It doesn't make sense to support only COPY then
2. We really are doing the job of the scheduler here

Note that SDISel does some scheduling, maybe the problem is there?
