gcc -S option

gcc -S option

[Shanks]

Hi,

Assume hypothetical C code below
int
main()
{
        int t;

        t += 1;
        return 0;
}

When i compile this code using -S option on a *solaris* box using
the *solaris* compiler, i get following .s file
! File a.c:
!    1  int
!    2  main()
!    3  {
!    4          int t;
!    5
!    6          t += 1;

        add     %i5,1,%i5

!    7          return 0;

        mov     %g0,%i0
        jmp     %i7+8
        restore

As you can see above, the .s file generated is of following
format:
- C code block
- Corresponding Assembly code

However when i do the same thing using gcc i get *only* the
assembly code and not the corresponding C code also.

Can someone tell me if i need to pass some extra options
while compiling using gcc to get the desired data.

Right now i am generating .s as follows
$ gcc -S a.c

Thanks in advance,
Shanks

I think you can't. You can use objdump with '-dS' to dump a mixture
of asm and C code, when that is possible.
