Hello. I've tried fiddling with the code on my own, and it doesn't
seem to work. What I'd like to do is divide two integers to get their
quotient, then use inline assembly to get the remainder at the same
time and put it somewhere else. Unfortunately, I'm stymied. The code
should look something like

remainder=0;
quotient = dividend/divisor;

__asm__ __volatile__ ("movw %%ax, SOMETHING" :   :   :);
                                  ^^^^^^^^^  ^^^^^^^^^
               the variable "remainder"  |         |
                                                   |
                                 what goes here?----

Please help me fill in the blanks...this code is inside two nested loops
and needs to be as fast as possible.

Thanks in advance,
jasonp

PS: this is part of a program to calculate pi, and I'd be happy to post
    or mail a copy to anyone interested (it's rather fast already; this
    will make it blinding :)
