I wrote a small document about using assembly language for
entire functions in .s files, rather than inline, a long time
ago.  I know of some errors in it, but generally I think it's
correct.

    http://users.ox.ac.uk/~mert0407/asmfuncs.txt

In particular note the calling conventions.  The document
doesn't point out that they only apply when your functions call
gcc-compiled code or gcc-compiled code calls your functions.  
How your assembly language functions interact with each other is
entirely up to you.
