From 285932a25879602407f207e862bc5b8416711f42 Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Wed, 2 Nov 2016 14:35:48 +0100 Subject: [PATCH] tools build: Add jvmti feature detection support Adding support to detect jvmti support. It is not plugged into the FEATURE_TESTS machinery, because it's quite rare and will be used separately from perf via feature_check call.
