From 1179e11bbb655162e83b33e17a97c45d3fe292da Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Mon, 14 Oct 2013 13:43:39 +0300 Subject: [PATCH] perf annotate: Fix annotate_browser__callq() When following a call, annotate_browser__callq() uses the current symbol's map to look up the target ip. That will not work if the target ip is on a map with a different mapping (i.e. start - pgoff is different).
