Various CPU backends (but IIRC not i386) implement a naked function

could implement something like that.
It seems to be what I want. Could you please

to let GCC produce assembly for it, how should
I code the machine description file? Should I first let cc1 produce a
elf assembly for it, and then let binutils trunate it to a flat

Hi,
Thanks for your attention and response. I think I am still not very
accurate to describe what I want to do. I am too anxious to explain far
from clearly. Now permit me use a simple example, for the simple C
program below, compiled by cc1 targetting to x86 platform, the assembly
is as
