Subject: [PATCH v2 47/71] target/arm: Export unpredicated ld/st from translate-sve.c
Date: Tue,  7 Jun 2022 13:32:42 -0700	[thread overview]
Message-ID: <20220607203306.657998-48-richard.henderson@linaro.org> (raw)
In-Reply-To: <20220607203306.657998-1-richard.henderson@linaro.org>

Add a TCGv_ptr base argument, which will be cpu_env for SVE.
We will reuse this for SME save and restore array insns.
