I'm a bit surprised that this conversation is going on at all.  We got the
%= output specifier which is perfectly fine to handle this problem, and it
is documented in md.texi.

int simple_func (int b, int c)
{ 
    int x;
asm ( 
"simple_func_loop_start%=:\n\t"
"    Do Assebly Stuff    \n\t"
"    LOOP to simple_func_loop_start%="
: [x] "=r" (x)
: [b] "r" (b), [c] "r" (c)
: "r0", "r1", "memory" );

    return x;
}
