Subject: [PATCH 1/6] target/riscv: move gen_nanbox_fpr to translate.c
Date: Sat, 27 Jun 2020 04:59:12 +0800	[thread overview]
Message-ID: <20200626205917.4545-2-zhiwei_liu@c-sky.com> (raw)
In-Reply-To: <20200626205917.4545-1-zhiwei_liu@c-sky.com>

As this function will be used by fcvt.d.s in trans_rvd.inc.c,
make it a visible function for RVF and RVD.
