Subject: [PATCH 11/12] tcg/mips: Use qemu_build_not_reached for LO/HI_OFF
Date: Fri, 7 Apr 2023 20:03:58 -0700 [thread overview]
Message-ID: <20230408030359.3368868-12-richard.henderson@linaro.org> (raw)
In-Reply-To: <20230408030359.3368868-1-richard.henderson@linaro.org>
The new(ish) macro produces a compile-time error instead
of a link-time error.
Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
