Subject: [PATCH v2 31/71] target/arm: Move error for sve%d property to arm_cpu_sve_finalize
Date: Tue, 7 Jun 2022 13:32:26 -0700 [thread overview]
Message-ID: <20220607203306.657998-32-richard.henderson@linaro.org> (raw)
In-Reply-To: <20220607203306.657998-1-richard.henderson@linaro.org>
Keep all of the error messages together. This does mean that
when setting many sve length properties we'll only generate
one error, but we only really need one.
