Subject: [PATCH -resend 08/27] x86: assembly, annotate aliases
Date: Thu, 10 May 2018 10:06:25 +0200 [thread overview]
Message-ID: <20180510080644.19752-9-jslaby@suse.cz> (raw)
In-Reply-To: <20180510080644.19752-1-jslaby@suse.cz>
_key_expansion_128 is an alias to _key_expansion_256a, __memcpy to
memcpy, xen_syscall32_target to xen_sysenter_target, and so on. Annotate
them all using the new SYM_FUNC_START_ALIAS, SYM_FUNC_START_LOCAL_ALIAS,
and SYM_FUNC_END_ALIAS. This will make the tools generating the
debuginfo happy.
