You could have 2 files:
 - 1 which contains the function, and a marker where prolog ends
(beginning of file is implicit marker of where it begins)
 - 1 which contains the function, and a marker where epilog begins
(end of file is implicit marker of where it ends)

Or just look at ./sysdeps/x86_64/elf/initfini.c, its a single asm()
block containing all relevant markers, and no C code.
I think thats better than all these hacks to get the asm you want out of
C code.
