Subject: [Qemu-devel] [PATCH v2 05/12] cpus: remove icount handling from qemu_tcg_cpu_thread_fn
Date: Wed,  5 Apr 2017 14:24:56 +0100	[thread overview]
Message-ID: <20170405132503.32125-6-alex.bennee@linaro.org> (raw)
In-Reply-To: <20170405132503.32125-1-alex.bennee@linaro.org>

We should never be running in multi-threaded mode with icount enabled.
There is no point calling handle_icount_deadline here so remove it and
assert !use_icount.
