From 5d7be90ed5cfb5dd3c9ab726d7daa91b86b81747 Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Tue, 20 Mar 2012 19:15:40 +0100 Subject: perf tools: Fix modifier to be applied on correct events The event modifier needs to be applied only on the event definition it is attached to. The current state is that in case of multiple events definition (in single '-e' option, separated by ',') all will get modifier of the last one. Fixing this by adding separated list for each event definition, so the modifier is applied only to proper event(s). Added automated test to catch this, plus some other modifier tests.
