Where can I find documentation on how to interface asm routines with
C/C++ routines when linking with GCC?
I am interested in seeing how things should be pushed onto the stack
and how returned objects should be extracted from the stack.

This is what I have done. And yes, it does work. I was just looking
for a more official method.

One of the easiest ways is to do “gcc -S” and take a look at the generated
assembly code.

Take a peek at the ABI for the achitecture you’re interested in, that should
the offical way for call linkage (stack or not).

Are you trying to write straight assembly files or inline assembly? If
inline, this page might be helpful.

There’s also one for DJGPP (a windows port of gcc) that is pretty good:
