From 59ee68ecd1561a233fb6ad351980bea8402533e7 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Thu, 14 Jan 2010 23:45:29 -0200 Subject: [PATCH] perf symbols: Create thread__find_addr_map from thread__find_addr_location MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Because some tools will only want to know with maps had hits, not needing the full symbol resolution done by thread__find_addr_location.
