Subject: [PULL v3 73/91] target/arm: Improve trans_BFCI
Date: Mon, 13 Mar 2023 11:59:03 -0700 [thread overview]
Message-ID: <20230313185903.400351-2-richard.henderson@linaro.org> (raw)
In-Reply-To: <20230313185903.400351-1-richard.henderson@linaro.org>
Reorg temporary usage so that we can use tcg_constant_i32.
tcg_gen_deposit_i32 already has a width == 32 special case,
so remove the check here.
