Subject: [PATCH 2/4] compat/regex: silence `make sparse` warning
Date: Thu, 23 Apr 2020 20:47:54 +0700 [thread overview]
Message-ID: <25f595f56f7f895ab31bf7269aabad9142c0590c.1587648870.git.congdanhqx@gmail.com> (raw)
In-Reply-To: <cover.1587648870.git.congdanhqx@gmail.com>
* alloca: somewhere later in the code, we indirectly include alloca.h
which will define alloca again, include it prior to define alloca in
order to not define it against.
* Copy all attributes from the header to source file, and move the
attributes prior to function name. cgcc is very picky on the position
of attribute.
