This revision is now accepted and ready to land.

Thanks Matt for the clarifications.
LGTM.

if shareSameRegisterFile is not used, maybe sink its implementation in the generic shouldRewriteCopySrc.
Targets can still call the parent method when overriding.

This is just a suggestion though, I am fine with the patch as it is. Up to you.

Cheers,
