| 2 | 1 | ||
| 3 | The vCont packet accepts a series of actions, each being applied on a | ||
| 4 | given thread ID. Giving no thread ID for an action is valid and means | ||
| 5 | "all threads". | ||
| 6 | |||
| 7 | This commit fixes vCont packets being incorrectly rejected when no | ||
| 8 | thread ID was given for an action. | ||
| 9 | |||
| 10 | In multiprocess mode, the GDB Remote Protocol specification is unclear | ||
| 11 | on what "all threads" means. We choose to apply the action on all | ||
| 12 | threads of all attached processes. | ||
| 13 | |||
| 14 | This commit is based on the initial fix by Lucien Murray-Pitts. | ||
