Subject: [RFC PATCH v2 24/24] target/mips/mod-msa: Pass TCGCond argument to gen_check_zero_element()
Date: Tue, 15 Dec 2020 23:57:57 +0100 [thread overview]
Message-ID: <20201215225757.764263-25-f4bug@amsat.org> (raw)
In-Reply-To: <20201215225757.764263-1-f4bug@amsat.org>
Simplify gen_check_zero_element() by passing the TCGCond
argument along.
Suggested-by: Richard Henderson <richard.henderson@linaro.org>
Signed-off-by: Philippe Mathieu-Daudé <f4bug@amsat.org>

Maybe this can be named 'msa_translate.c' after all...
