Subject: [PATCH 1/5] target/loongarch: ftint_xxx insns set the result high 32bit 0xffffffff
Date: Sat, 17 Sep 2022 15:59:46 +0800	[thread overview]
Message-ID: <20220917075950.1412309-2-gaosong@loongson.cn> (raw)
In-Reply-To: <20220917075950.1412309-1-gaosong@loongson.cn>

we just set high 32bit 0xffffffff as the other float instructions do.
