("[PATCH v3 0/5] gdbstub: Implement catching syscalls")v1: https://lists.gnu.org/archive/html/qemu-devel/2024-01/msg06646.html v1 -> v2: Factor out a number of prep patches; Add a state transition diagram comment (Alex). Improve a few comments; Extend the ts_tid fix to bsd. Hi, I needed to debug a linux-user crash between fork() and exec() [1] and realized that gdbstub does not allow this. This series lifts this restriction (one still cannot debug past exec() though). Patches 1-9 are preliminary refactorings, patch 10 is the implementation, and patch 11 is the test.
