Subject: [PATCH 5/6] target/mips: Use hswap_i64() in DSHD opcode
Date: Tue, 22 Aug 2023 13:01:28 +0200	[thread overview]
Message-ID: <20230822110129.41022-6-philmd@linaro.org> (raw)
In-Reply-To: <20230822110129.41022-1-philmd@linaro.org>

Commit 46be8425ff ("tcg: Implement tcg_gen_{h,w}swap_{i32,i64}")
introduced the generic hswap_i32(). Use it instead of open-coding
it in gen_bshfl().
