--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Inline-asm is basically a black box.
In this case since the outputs are different, GCC is not going to merge them.
Also I am not sure why you didn't just write the division/mod in C.
Not also your inline-asm for both myMod is broken.
In the case of myDiv, dummyDividendHigh and b cannot be the same register as
you zero out dummyDividendHigh early.
myMod has a similar issue too. But it has an additional issue of not marking
eax as being clobbered.
