Subject: [PATCH v2 19/20] tests/tcg/multiarch: Adjust sigbus.c
Date: Thu, 25 May 2023 16:25:57 -0700 [thread overview]
Message-ID: <20230525232558.1758967-20-richard.henderson@linaro.org> (raw)
In-Reply-To: <20230525232558.1758967-1-richard.henderson@linaro.org>
With -cpu max and FEAT_LSE2, the __aarch64__ section will only raise
an alignment exception when the load crosses a 16-byte boundary.
Reviewed-by: Peter Maydell <peter.maydell@linaro.org>
