Subject: [PATCH 15/25] [RFC] GDBserver unit test to i386_tdesc
Date: Mon, 12 Jun 2017 08:42:00 -0000 [thread overview]
Message-ID: <1497256916-4958-16-git-send-email-yao.qi@linaro.org> (raw)
In-Reply-To: <1497256916-4958-1-git-send-email-yao.qi@linaro.org>
This patch adds a unit test in GDBserver to test dynamically created
target descriptions equal to these pre-generated ones.
gdb/gdbserver:
2017-06-06 Yao Qi <yao.qi@linaro.org>
* linux-x86-tdesc.c (i386_tdesc_test): New function.
(initialize_low_tdesc): Call register_self_test.
* tdesc.h: TODO.
