| 3 | * frame.c (backtrace_past_zero_pc): New static variable. | |
| 4 | (get_prev_frame): Don't return NULL for zero pc value if | |
| 5 | backtrace past-zero-frame option is turned on. | |
| 6 | (_initialize_frame): Initialize new command to allow backtracing | |
| 7 | past a zero pc value (set backtrace past-zero-pc). | |
