Subject: [PATCH 3/6] Coccinelle: atomic_as_refcounter: Use type “expression” for another metavariable
Date: Tue, 3 Jul 2018 09:40:30 +0200	[thread overview]
Message-ID: <c87de98e-9566-0bac-8264-8bc2a6e06d51@users.sourceforge.net> (raw)
In-Reply-To: <6043bdc9-529f-e93f-e509-e2dedd290a10@users.sourceforge.net>

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Mon, 2 Jul 2018 17:55:27 +0200

The metavariable “a” is enclosed by parentheses in three rules of
a script for the semantic patch language.
Replace its type by “expression” so that the corresponding source code
search becomes more powerful.
