I think it might end up looking a bit like the
optimizers that were
used on drum memory computers back in the dark ages.
I dunno; those were all about picking _addresses_ for instructions, such
that the next instruction was coming up to the heads as the last one
completed.
The _order_ of execution wasn't changed, there was no issue of contention
for computing elements, etc - i.e. all the things ones think of a
CISC->VLIW translation as doing.
