            Bug ID: 60877
           Summary: __attribute__optimize("O0") conflict with static
                    function at -O1
           Product: gcc
           Version: 4.7.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: mnp at agtmt dot com

Created attachment 32628
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=32628&action=edit
preprocessed .i file

#include <stdio.h>

static int sub1(int i, int j)
{
    return j;
}

void __attribute__((optimize("O0"))) main(void)
{
    int k;
    k = sub1(0, 1);
    printf("%d\n",k);
}

gcc -O1

if sub1() is static, return is wrong  
   movl    %edx, %eax
   ret 

if not static, return is correct
    movl    8(%esp), %eax
    ret

gcc version 4.7.2 20130108 [gcc-4_7-branch revision 195012] (SUSE Linux)

--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
This is a target specific issue where the target is changing the ABI but not
changing the ABI for the callee function.
