From 9aeedfc71ce8427c0c770f38df34f47e73f27cfa Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Tue, 5 Nov 2019 00:27:11 +0100 Subject: perf tools: Fix time sorting commit 722ddfde366fd46205456a9c5ff9b3359dc9a75e upstream. The final sort might get confused when the comparison is done over bigger numbers than int like for -s time. Check the following report for longer workloads: $ perf report -s time -F time,overhead --stdio Fix hist_entry__sort() to properly return int64_t and not possible cut int.
