Subject: [PATCH v2 07/24] accel/tcg: Validate placement of CPUNegativeOffsetState
Date: Wed, 13 Sep 2023 19:44:18 -0700 [thread overview]
Message-ID: <20230914024435.1381329-8-richard.henderson@linaro.org> (raw)
In-Reply-To: <20230914024435.1381329-1-richard.henderson@linaro.org>
Verify that the distance between CPUNegativeOffsetState and
CPUArchState is no greater than any alignment requirements.
