This is going to return ret.allocated = true, which seems problematic.
There's another similar case above.

It's most likely never going to matter (and right now it doesn't make any difference for sure) but to go "in order" you would allocate the temporary registers for instructions after assigning them for the variables used by the instruction. ... I think you can safely ignore this one.
