Subject: [kvm-unit-tests PATCH 7/7] x86: VMX: the "noclone" attribute is gcc-specific
Date: Wed, 26 Feb 2020 01:44:33 -0800	[thread overview]
Message-ID: <20200226094433.210968-15-morbo@google.com> (raw)
In-Reply-To: <20200226094433.210968-1-morbo@google.com>

Don't use the "noclone" attribute for clang as it's not supported.
