Subject: [PATCH 05/54] perf build: Use feature dump file for build-test
Date: Mon, 25 Jan 2016 09:55:52 +0000 [thread overview]
Message-ID: <1453715801-7732-6-git-send-email-wangnan0@huawei.com> (raw)
In-Reply-To: <1453715801-7732-1-git-send-email-wangnan0@huawei.com>
To prevent feature check run too many times, this patch utilizes
previous introduced feature-dump make target and FEATURES_DUMP
variable, makes sure the feature checkers run only once when doing
build-test for normal test cases.
