Subject: [PATCH 11/13] target/riscv: Adjust trans_rev8_32 for riscv64
Date: Thu, 7 Oct 2021 10:47:20 -0700 [thread overview]
Message-ID: <20211007174722.929993-12-richard.henderson@linaro.org> (raw)
In-Reply-To: <20211007174722.929993-1-richard.henderson@linaro.org>
When target_long is 64-bit, we still want a 32-bit bswap for rev8.
Since this opcode is specific to RV32, we need not conditionalize.
Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
