From 1e3f30fae797660a014ac159d93fff9952ec1bf0 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Wed, 2 Oct 2013 15:48:49 +0200 Subject: tools/perf/build: Clean up various testcases Prepare to include them into test-all.c directly, by making sure that they build cleanly and without warnings. Also make sure they make a certain amount of sense and don't crash when executed.
