From dd464345f330c1103f93daad309e8b44845e96cf Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Thu, 4 Oct 2012 21:49:36 +0900 Subject: perf diff: Refactor diff displacement possition info Moving the position calculation into the diff command, so the position as prepared inside struct hist_entry data and there's no need to compute in the output display path. Removing 'displacement' from struct perf_hpp as it is no longer needed.
