Subject: [PATCH v4 17/18] perf clang builtin: Define hook helpers by default
Date: Tue, 6 Dec 2016 07:13:55 +0000 [thread overview]
Message-ID: <20161206071356.5312-18-wangnan0@huawei.com> (raw)
In-Reply-To: <20161206071356.5312-1-wangnan0@huawei.com>
Append declarations of helpers to default include file. All functions
appear in exported_funcs array should be declared here except
test__clang_callback, because it is used for perf test only.
