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: unassigned@gcc.gnu.org
ReportedBy: deepak.kansl@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?
