From 1c47661a93fe6f729c80ed18a1f9ab1c7fb0cac2 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Wed, 2 Oct 2013 15:15:09 +0200 Subject: tools/perf/build: Split out feature checks: 'liberty', 'liberty-z', 'cplus-demangle' Note that these are rarely executed tests, so we call feature_check() explicitly and don't have them in CORE_FEATURE_CHECKS.
