After some further discussion on the DragonFly lists and further reading on my
part, I found out that %sil and %dil are the 8-bit equivalents of %al, %bl, etc.
(Watch the light bulb undim in my head here :-)
It would be better if gcc were able to diagnose the problem code better (ensure
that the architecture is valid before emitting a %sil/%dil/%bpl/%spl register)
-- I'll see if I can't ponder on this and propose a small patch.
