             Bug #: 56960

           Summary: How to set up stack pointer in gcc 4.7.2

    Classification: Unclassified

           Product: gcc

           Version: 4.7.2

            Status: UNCONFIRMED

          Severity: normal

          Priority: P3

         Component: c

        AssignedTo: unassig...@gcc.gnu.org

        ReportedBy: deepak.ka...@gmail.com

{

        int i,j;



       

emit_move_insn(gen_rtx_MEM(SImode,plus_constant(stack_pointer_rtx,-0)),return_addr_rtx);

       

emit_move_insn(gen_rtx_MEM(SImode,plus_constant(stack_pointer_rtx,-4)),stack_pointer_rtx);

       

emit_move_insn(gen_rtx_MEM(SImode,plus_constant(stack_pointer_rtx,-8)),hard_frame_pointer_rtx);

        emit_move_insn(hard_frame_pointer_rtx,

plus_constant(stack_pointer_rtx,0));

        for(i=0,j=4;i<FIRST_PSEUDO_REGISTER;i++)

        {

                if(df_regs_ever_live_p(i) && !call_used_regs[i] &&

!fixed_regs[i])

                {

                       

emit_move_insn(gen_rtx_MEM(SImode,plus_constant(hard_frame_pointer_rtx,-4*j)),

gen_rtx_REG(SImode,i));

                        j++;

                }

        }

        emit_insn(gen_rtx_SET(SImode,

stack_pointer_rtx,plus_constant(hard_frame_pointer_rtx,-((3+j+1)*4+get_frame_size()))

));  //HERE is what error comes

}



The last statement of the program is producing a segmentation fault when I

compile a program. It worked fine when it was built on gcc-4.6.2 but creating

problem for 4.7.2.  Can anyone help me out?
