Yep, sorry about the delay. That addition to addRegisterKilled needs some careful thought, since this isn't the only user.

The debug operand is probably fine, but it seems completely unobvious to me that all other users will want to skip internal reads, so we've got to think about all other call-sites. Not helped by the fact that I can't even see why it's necessary in **this** case yet.

I haven't forgotten though!
