| 16 | # This test covers a case where SIGSTOP has been configured to be | |
| 17 | # passed to the target with GDB's 'handle' command, and then a | |
| 32d1f47a | 18 | # multi-threaded inferior encounters an event that causes all threads |
| d8c06f22 AB |
19 | # to be stopped. |
| 20 | # | |
| 21 | # The problem that (used) to exist was that GDB would see the SIGSTOP, | |
| 22 | # but decide to ignore the signal based on the handle table. | |
