From 3cf0cb1f899640f1eb8b3984739cfd70375c9c36 Mon Sep 17 00:00:00 2001 From: Stephane Eranian Date: Mon, 14 Jan 2013 15:02:45 +0100 Subject: [PATCH] perf tools: Mark branch_info maps as referenced As noticed by Jiri, the hist_entry->branch_info.to/from maps need to be marked as referenced to avoid problems later on. So we do this when the hist_entry is allocated.
