[PATCH] D82765: GlobalISel: Disallow undef generic virtual register uses

[Adrian Prantl via Phabricator via llvm-commits]

aprantl added a comment.

My MIR is lacking here: What does it mean for a USE to be UNDEF? DBG_VALUE accepts UNDEF as an operand, but it's not clear to me what an undef vreg means / how it can be created.
