From: Arnaldo Carvalho de Melo Date: Wed, 24 Mar 2010 19:40:17 +0000 (-0300) Subject: perf tools: Introduce struct map_symbol X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=59fd53062f71011a68d03f4cd0ba93d822ac3249;p=linux-beck.git perf tools: Introduce struct map_symbol That will be in both struct hist_entry and struct callchain_list, so that the TUI can store a pointer to the pair (map, symbol) in the trees where hist_entries and callchain_lists are present, to allow precise annotation instead of looking for the first symbol with the selected name.
