Subject: [PATCH 05/16] gdbserver: don't define HAVE_SYNC_BUILTINS
Date: Tue, 13 Oct 2026 11:35:51 -0400 [thread overview]
Message-ID: <20261013153657.1610298-6-simon.marchi@efficios.com> (raw)
In-Reply-To: <20261013153657.1610298-1-simon.marchi@efficios.com>
Nothing uses HAVE_SYNC_BUILTINS. Remove the AC_DEFINE from
configure.ac. The check itself stays, since its result decides
whether the in-process agent is built.
Regenerate config.in and configure.
