<thinking aloud followups_to="chat@freebsd.org">
is this the sort of thing that a compiler _in_theory_ could/should do
well, or is this the kind of assembler code that only a human could be
expected to come up with?

If the former, then I may be interested in spending some years reading
up on compiler/optimisation technology.

I'm not too charmed with MD code; the more that could be done by the
compiler, the more I like it. :-)
