From 787bef174f055343c69a9639e6e05a564980ed4c Mon Sep 17 00:00:00 2001 From: David Ahern Date: Fri, 27 May 2011 14:28:43 -0600 Subject: perf script: "sym" field really means show IP data Currently the "sym" output field is used to dump instruction pointers and callchain stack. Sample addresses can also be converted to symbols, so the meaning of "sym" needs to be fixed. This patch adds an "ip" option and if it is selected the user can also opt to dump symbols for them. If the user opts to dump IP without syms only the address is shown.
