From a341d96add049e1ebc94e7350ff59e82b03043d2 Mon Sep 17 00:00:00 2001 From: Jonathan Wakely Date: Fri, 9 May 2025 11:39:39 +0100 Subject: libstdc++: Suppress GDB output from new 'skip' commands [PR118260] MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit I added some gdb.execute('skip -rfu ...') commands to the Python hook loaded with libstdc++.so but this makes GDB print output like: Function(s) ^std::(move|forward|as_const|(__)?addressof) will be skipped when stepping. This probably aren't interesting to users, so this change suppresses that output by capturing the output into the gdb.execute return value (which is then ignored). An exception is thrown if the gdb.execute command fails, so this doesn't suppress any errors which might be meaningful to users or libstdc++ developers. libstdc++-v3/ChangeLog: PR libstdc++/118260 * python/hook.in: Suppress output from gdb.execute calls to register skips.
