Subject: [PATCH  v1 2/9] Makefile: add GNU global tags support
Date: Wed, 13 Jan 2021 15:14:01 +0000	[thread overview]
Message-ID: <20210113151408.27939-3-alex.bennee@linaro.org> (raw)
In-Reply-To: <20210113151408.27939-1-alex.bennee@linaro.org>

GNU Global is another tags engine which is more like cscope in being
able to support finding both references and definitions. You will be
un-surprised to know it also integrates well with Emacs.

The main benefit of integrating it into find-src-path is it takes less
time to rebuild the database from scratch when you have a lot of build
directories under your source tree.
