Subject: [PATCH 12/22] perf tools: Introduce opt_event_config nonterminal
Date: Fri, 19 Feb 2016 19:41:26 -0300 [thread overview]
Message-ID: <1455921696-3895-13-git-send-email-acme@kernel.org> (raw)
In-Reply-To: <1455921696-3895-1-git-send-email-acme@kernel.org>
From: Arnaldo Carvalho de Melo <acme@redhat.com>
To remove duplicated code that differs only in using the matching
'/a,b,c/' part or NULL if no event configuration is done ('//' or no
pair of slashes at all).
Will be used by some new targets allowing the configuration of hardware
events, etc.
Lifted part of the 'opt_event_config' nonterminal from a patch by Wang
Nan.
