Date: Wed, 15 Jul 2020 16:44:54 -0300 [thread overview]
Message-ID: <20200715194513.16641-5-luis.machado@linaro.org> (raw)
In-Reply-To: <20200715194513.16641-1-luis.machado@linaro.org>
Include some unit testing for the functions handling the new qMemTags and
QMemTags packets.
gdb/ChangeLog:
YYYY-MM-DD Luis Machado <luis.machado@linaro.org>
* remote: Include gdbsupport/selftest.h.
(test_memory_tagging_functions): New function.
(_initialize_remote): Register test_memory_tagging_functions.
