From 354cc40e3b0981c38ba2ce2964954480e6c03c37 Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Tue, 1 Oct 2013 07:22:15 -0700 Subject: [PATCH] tools/perf: Fix sorting for 64bit entries Some of the node comparisons in hist.c dropped the upper 32bit by using an int variable to store the compare result. This broke various 64bit fields, causing incorrect collapsing (found for the TSX transaction field) Just use int64_t always.
