There's a documentation for gas (the GNU assembler) available in
texinfo format.  You need an `info' browser to read it.  Emacs has a
builtin one, there's also a separate tool named `info'.  Don't know
about DOS/Windows tools.

gas is mainly intended to be a backend assembler for high-level
languages.  It doesn't seem to have the ability to use macros.

As for calling an external C function, it's probably best to have a
look into the compiler-generated assembler code.

The other way around might be more suitable: write all the framework
in C, and include your assembler code for time-critical functions
inside a C function as `asm("...");'.
