Hello,
I intend to implement variable expansion
in the body of the unrolled loop.
I take it you are proposing to do this in the RTL loop unrollers?
(On trees, we would want to maintain SSA form, so we'd have to do the
renaming you're suggesting anyhow.)
I'd hope that soon we'd be able to get rid of the RTL-based loop
unroller, but I'm perfectly willing to believe that day to be a ways away...
