Subject: [PATCH v4 35/48] target/alpha: Reorg fp memory operations
Date: Tue, 12 Oct 2021 19:45:54 -0700 [thread overview]
Message-ID: <20211013024607.731881-36-richard.henderson@linaro.org> (raw)
In-Reply-To: <20211013024607.731881-1-richard.henderson@linaro.org>
Pass in the context to each mini-helper, instead of an
incorrectly named "flags". Separate gen_load_fp and
gen_store_fp, away from the integer helpers.
Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
