Here's some -S output from gcc for linux/x86:

    .file    "whello.c"
    .version    "01.01"
gcc2_compiled.:
.data
    .type     hello.0,@object
    .size     hello.0,15
hello.0:
    .string    "Hello, world!\n"
.text
    .align 16
.globl main
    .type     main,@function
main:
    subl    $12, %esp
    subl    $4, %esp
    pushl    $14
    pushl    $hello.0
    pushl    $1
    call    write
    addl    $16, %esp
    xorl    %eax, %eax
    addl    $12, %esp
    ret
.Lfe1:
    .size     main,.Lfe1-main
    .ident    "GCC: (GNU) cygnus-2.96 20000103"
