Subject: [PATCH v2 3/8] Coccinelle: atomic_as_refcounter: Optimise a disjunction in the first SmPL rule
Date: Mon, 16 Jul 2018 19:28:38 +0200	[thread overview]
Message-ID: <9941258f-9243-6400-3c93-ea0637da3e0d@users.sourceforge.net> (raw)
In-Reply-To: <5ca6ab58-e929-8468-74e2-012f987a0773@users.sourceforge.net>

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Mon, 16 Jul 2018 17:43:49 +0200

The variables “fname2” till “fname6” do not care for different function
parameters in the disjunction at the end of a rule in a script
for the semantic patch language.
Thus reduce this disjunction by using a regular expression with
an alternation for an optimised constraint.
