Subject: [Qemu-devel] [PATCH 10/12] target/arm: stop using deprecated functions in NEON_2RM_VCVT_F16_F32
Date: Thu, 13 Jun 2019 17:39:15 +0100	[thread overview]
Message-ID: <20190613163917.28589-11-peter.maydell@linaro.org> (raw)
In-Reply-To: <20190613163917.28589-1-peter.maydell@linaro.org>

Remove some old constructs from NEON_2RM_VCVT_F16_F32 code:
 * don't use cpu_F0s
 * don't use tcg_gen_ld_f32
