Subject: [PATCH 6/8] perf annotate browser: Count the numbers of jump sources to a target
From: Arnaldo Carvalho de Melo <acme@...hat.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.
