[PATCH 2/3] Enable ptrace events on new child processes.
- From: John Baldwin <jhb at FreeBSD dot org>
- To: gdb-patches at sourceware dot org
- Date: Mon, 18 Jul 2016 07:57:58 -0700
- Subject: [PATCH 2/3] Enable ptrace events on new child processes.
- Authentication-results: sourceware.org; auth=none
- References: <20160718145759.58543-1-jhb@FreeBSD.org>
New child processes on FreeBSD do not inherit optional ptrace events
such as fork and LWP events from the parent process. Instead,
explicitly enable events on new children when reporting a fork
event.
gdb/ChangeLog:
* fbsd-nat.c (fbsd_wait): Use "fbsd_enable_proc_events" on
new child processes.
