From 69aad6f1ee69546dea8535ab8f3da9f445d57328 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Mon, 3 Jan 2011 16:39:04 -0200 Subject: perf tools: Introduce event selectors Out of ad-hoc code and global arrays with hard coded sizes. This is the first step on having a library that will be first used on regression tests in the 'perf test' tool.
