It's for bitsizetype here, as it's a conversion from bits into bytes, so
larger than DWARF2_ADDR_SIZE.

case UDIV:
if ((!dwarf_strict || dwarf_version >= 5)
&& is_a <scalar_int_mode> (mode, &int_mode))
{
if (GET_MODE_SIZE (int_mode) > DWARF2_ADDR_SIZE)
{
op = DW_OP_div;
goto do_binop;
}
mem_loc_result = typed_binop (DW_OP_div, rtl,
base_type_for_mode (int_mode, 1),
int_mode, mem_mode);
}
break;
This also looks incorrect if the size is larger than DWARF2_ADDR_SIZE then,
isn't there a typo in the code?
if (GET_MODE_SIZE (int_mode) < DWARF2_ADDR_SIZE)
{
op = DW_OP_div;
goto do_binop;
}
