Subject: [Qemu-devel] [PULL 02/11] target/i386/cpu.h: declare TCG_GUEST_DEFAULT_MO
Date: Thu, 9 Mar 2017 11:17:05 +0000 [thread overview]
Message-ID: <20170309111714.20394-3-alex.bennee@linaro.org> (raw)
In-Reply-To: <20170309111714.20394-1-alex.bennee@linaro.org>
This suppresses the incorrect warning when forcing MTTCG for x86
guests on x86 hosts. A future patch will still warn when
TARGET_SUPPORT_MTTCG hasn't been defined for the guest (which is still
pending for x86).
