Subject: [PATCH 6/8] perf annotate browser: Count the numbers of jump sources to a target
Date: Sat, 12 May 2012 16:53:05 -0300	[thread overview]
Message-ID: <1336852387-16322-7-git-send-email-acme@infradead.org> (raw)
In-Reply-To: <1336852387-16322-1-git-send-email-acme@infradead.org>

From: Arnaldo Carvalho de Melo <acme@redhat.com>

Instead of simply marking an offset as a jump target. So that we can
implement a new feature: showing "jumpy" targets, I.e. addresses that
lots of places jump to.
