Prior to commit0e3c1eebb2nm output depended on the host unsigned long when printing "negative" symbol values for 32-bit targets. Commit0e3c1eebb2made the output match that seen with a 64-bit host unsigned long. The fact that nm output changed depending on host is of course a bug, but it is reasonable to expect 32-bit target output is only 32 bits. So this patch makes 32-bit target output the same as it was on 32-bit hosts prior to0e3c1eebb2. PR 31096 * nm.c (print_format_string): Make it a static buffer. (get_print_format): Merge into.. (set_print_format): ..this, renamed from set_print_width. When print_width is 32, set up print_format_string for an int32_t value. Don't malloc print_format_string. Adjust calls. (print_value): Correct printing of 32-bit values.
