Oh no, my index is always an integer. This bit applies to the
"live-in" bits - if the loop performs floating-point computation, it's
floating-point registers that I want to mark as forwarding nodes.

And so you indicate this explicitly in VVM as well. I tended to assume
only a limited number of registers would be needed to live in, plus I
have both floating and integer register files, hence the differences.
