From 4adcc43003024354b45edadfad4ea2fa205f135f Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Wed, 11 Sep 2013 14:09:33 +0900 Subject: [PATCH] perf tools: Fix srcline sort key behavior Currently the srcline sort key compares ip rather than srcline info. I guess this was due to a performance reason to run external addr2line utility. Now we have implemented the functionality inside, use the srcline info when comparing hist entries. Also constantly print "??:0" string for unknown srcline rather than printing ip.
