   Hello to you all,

   My question isn't really useful, but I would like to understand:

   When "gcc asmtest.c -S" the code below:

void test1 () {
}

void main () {
test1();
}

   gcc makes the following .S code: (Without the lines numbers.)

1 .file "asmtest.c"
2 .section .text
3 .p2align 4
4 .globl _test1
5 _test1:
6 pushl %ebp
7 movl %esp, %ebp
8 popl %ebp
9 ret
10 .p2align 4
11 .globl _main
12 _main:
13 pushl %ebp
14 movl %esp, %ebp
15 subl $8, %esp
16 andl $-16, %esp
17 call _test1
18 movl %ebp, %esp
19 popl %ebp
20 ret
21 .ident "GCC: (GNU) 3.0.3"

   What is the purpose of the lines 15 and 16 ?
