Subject: [Qemu-devel] [PATCH v3 04/12] target/arm: Use tcg integer min/max primitives for neon
Date: Fri, 8 Feb 2019 19:38:39 -0800 [thread overview]
Message-ID: <20190209033847.9014-5-richard.henderson@linaro.org> (raw)
In-Reply-To: <20190209033847.9014-1-richard.henderson@linaro.org>
The 32-bit PMIN/PMAX has been decomposed to scalars,
and so can be trivially expanded inline.
Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
