.data segment

[ratheesh kannoth <ratheesh.ksz@gmail.com>]

Hi List,

When I compiled (gcc -O0 -g  --no-pic -S  -fverbose-asm -c  2.c  -o
2.s) below  program to assembly code, it showed an uninitialized
static variable, "sta_char_unini" section.
 But when we execute the program, I can see that  "sta_char_unini" is
in .data section (thru /proc/<pid>/maps). What is wrong in my analysis
of 2.s ?

===================   2.c ==================================
#include <stdio.h>
#include <stdint.h>
#include <unistd.h>

static char sta_char_unini;
static char sta_char_ini = 'B';

char char_unini;
char char_ini = '6';

int main()
{

        sta_char_unini = 5;

        char str1[] = "Hello world";
        char *str2  = "How are you";
        printf("Pid = %u\n", getpid());

        printf("sta_char_unini=%p sta_char_ini=%p\n", &sta_char_unini,
&sta_char_ini);

        while (1);

        return 0;
}

=================================== 2.s ===================

        .file   "2.c"
        .text
.Ltext0:
        .local  sta_char_unini
        .comm   sta_char_unini,1,1
        .data
        .type   sta_char_ini, @object
        .size   sta_char_ini, 1
sta_char_ini:
        .byte   66
        .comm   char_unini,1,1
        .globl  char_ini
        .type   char_ini, @object
        .size   char_ini, 1
char_ini:
        .byte   54
        .section        .rodata

        .string "Pid = %u\n"
        .align 8

        .string "sta_char_unini=%p sta_char_ini=%p\n"
        .text
        .globl  main
        .type   main, @function
