Subject: [PATCH v3 59/88] target/hppa: Remove remaining TARGET_REGISTER_BITS redirections
Date: Wed, 1 Nov 2023 18:29:47 -0700 [thread overview]
Message-ID: <20231102013016.369010-60-richard.henderson@linaro.org> (raw)
In-Reply-To: <20231102013016.369010-1-richard.henderson@linaro.org>
The conversions to/from i64 can be eliminated entirely,
folding computation into adjacent operations.
