Subject: [PATCH 06/19] Remove usage of find_inferior in last_thread_of_process_p
Date: Mon, 20 Nov 2017 16:35:00 -0000 [thread overview]
Message-ID: <1511195683-2055-7-git-send-email-simon.marchi@ericsson.com> (raw)
In-Reply-To: <1511195683-2055-1-git-send-email-simon.marchi@ericsson.com>
From: Simon Marchi <simon.marchi@polymtl.ca>
Replace it with find_thread. I also modified the code a bit to use a
lambda and a boolean.
gdb/gdbserver/ChangeLog:
* linux-low.c (struct counter): Remove.
(second_thread_of_pid_p): Remove.
(last_thread_of_process_p): Use find_thread.
