Date: Tue, 04 Sep 2012 12:32:30 +0200 From: Maciek Borzecki <maciek.borzecki@...il.com> To: Arnaldo Carvalho de Melo <acme@...stprotocols.net> Cc: "linux-kernel@...r.kernel.org" <linux-kernel@...r.kernel.org>, linux-perf-users@...r.kernel.org Subject: [PATCH] perf: allow user to indicate path to objdump in command line When analyzing perf data from hosts of other architecture than one of the local host it's useful to call objdump that is part of a toolchain for that architecture. Instead of calling regular objdump, call one that user specified in command line.
