From 7d5b12f5a01d338d23874c7c242a74813a8848b2 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Sat, 12 May 2012 13:40:52 -0300 Subject: [PATCH] perf annotate browser: Count the numbers of jump sources to a target 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.
