Subject: [PATCH 03/19] Remove usages of find_inferior in linux-mips-low.c
Date: Mon, 20 Nov 2017 16:35:00 -0000 [thread overview]
Message-ID: <1511195683-2055-4-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 with for_each_thread with pid filtering. This allows
simplifying the callback a little bit.
gdb/gdbserver/ChangeLog:
* linux-mips-low.c (update_watch_registers_callback): Return
void, remove pid_p parameter, don't check for pid.
(mips_insert_point, mips_remove_point): Use for_each_thread.
