Subject: [PATCH v3 11/29] x86: entry, annotate THUNKs
Date: Fri, 21 Apr 2017 16:12:47 +0200 [thread overview]
Message-ID: <20170421141305.25180-11-jslaby@suse.cz> (raw)
In-Reply-To: <20170421141305.25180-1-jslaby@suse.cz>
Place SYM_FUNC_START and SYM_FUNC_END around the THUNK macro body, given
it generates functions.
