Subject: [PATCH v2 01/55] hw/core: Make do_unaligned_access noreturn
Date: Mon, 2 Aug 2021 18:13:49 -1000 [thread overview]
Message-ID: <20210803041443.55452-2-richard.henderson@linaro.org> (raw)
In-Reply-To: <20210803041443.55452-1-richard.henderson@linaro.org>
While we may have had some thought of allowing system-mode
to return from this hook, we have no guests that require this.
Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
