I have made some functions in assembly and want to call them
from C (or vice versa). I have already got it to work, however..
What registers I should save and what registers are not needed
to save? I have saved everything with 'pushad' but that's
inefficient.
Reading GCC info page:
> GNU CC is normally configured to use the same function calling
>convention normally in use on the target system.
But GNU CC _defines_ what is the normally used calling convention.
So this is a recursive definition...
This is about all what the info page says. And as I don't have
GCC source and it's a bit big to download, I ask here.
I'm using Linux 2.0.34, GCC 2.7.2 and x86 (Pentium).
TIA
