Erm, the original topic of this dicussion was about attempting to use the
assembly from the C compiler to see how things work when writing one's own
assembly functions. Having to know magical extra parameters to pass to the
compiler to make this a fruitful exercise doesn't help. If the compiler were
more intelligent about the code it output by default in the first place, then
that would help.
