Compile intel assembly with gcc/mingw

Question

I want to compile intel syntax assembly using gcc. Is it possible? because I cant find something similar. I've only found this post.

Here is the code I am trying to compile.

    global  _main
    section .text
_main:
    mov eax, -1     
        ret

If this is not possible please provide alternative options in your answer.

Adding a .intel_syntax directive works for me:

  .globl _main
  .intel_syntax

_main:
  mov eax, -1     
  ret

Assembling and running:

$ gcc -o example example.s; ./example; echo $?

Works for me too. Where did you find that? – kechap Jan 18 '12 at 21:20

I did a Google search for "gcc intel syntax". It was either the first or second hit. – Carl Norum Jan 18 '12 at 21:22
gcc version 4.4.0 (GCC), which one you have? – kechap Jan 18 '12 at 21:29
Actually it forces you to have .s file extension to your file. That's why it didn't work. – kechap Jan 18 '12 at 21:57
Hi guys, I've got this working, but the comments in my code (starting with ';' have not been removed. Is there a solution to this?) – FreelanceConsultant Jul 25 '13 at 12:20

@EdwardBird, I think intel-syntax comments start with a `#`. – Carl Norum Jul 25 '13 at 13:53
@CarlNorum Oh, okay thanks... Why did I seem to think they began with ';' ? Is that an AT&T thing? – FreelanceConsultant Jul 25 '13 at 14:11
By the way, for anyone wondering I managed to get it to work by compiling with nasm first, and then linking using gcc instead of ld... Since I defined main not `_start` – FreelanceConsultant Jul 25 '13 at 14:11
