Subject: [PATCH 1/5] libthread_db: debug output should go to gdb_stdlog
Date: Tue, 16 Dec 2014 16:54:00 -0000 [thread overview]
Message-ID: <1418748834-27545-2-git-send-email-palves@redhat.com> (raw)
In-Reply-To: <1418748834-27545-1-git-send-email-palves@redhat.com>
Some debug output in linux-thread-db.c was being sent to gdb_stdout,
and some to gdb_stderr, while the right place to send debug output to is
gdb_stdlog.

* linux-thread-db.c (thread_db_find_new_threads_silently)
(try_thread_db_load_1, try_thread_db_load, thread_db_load_search)
(find_new_threads_once): Print debug output on gdb_stdlog.
