Subject: [PULL 12/27] tcg/tci: Remove tci_read_r8
Date: Sat, 6 Mar 2021 13:35:58 -0800 [thread overview]
Message-ID: <20210306213613.85168-13-richard.henderson@linaro.org> (raw)
In-Reply-To: <20210306213613.85168-1-richard.henderson@linaro.org>
Use explicit casts for ext8u opcodes, and allow truncation
to happen with the store for st8 opcodes.
