From 4d161f0360d00d46a89827b3fd6da395f00c5d90 Mon Sep 17 00:00:00 2001 From: Tom Zanussi Date: Wed, 27 Jan 2010 02:27:58 -0600 Subject: perf/scripts: Add syscall tracing scripts Adds a set of scripts that aggregate system call totals and system call errors. Most are Python scripts that also test basic functionality of the new Python engine, but there's also one Perl script added for comparison and for reference in some new Documentation contained in a later patch.

This requires being able to pass in e.g. '-i -' or other args, which the current shell scripts aren't equipped to handle. In a few cases, there are required or optional args that also need special handling. This patch makes changes the current set of shell scripts as necessary.
