Sorry, i can't follow you. ``inline function'' is something the
compiler expands similar to a macro, but syntactically a function. So
this per se cannot be assembler since it's handled by the compiler.
Do you want to write a function in an assembler file, and call it from
C? Of course, that's possible.

You can declare the function as __attribute__((naked)) which will make
the compiler emit no prologue and epilogue at all. Then plug in your
own {pro,epi}logue, supposedly using some inline asm magic.
