Subject: [PATCH v7 60/75] target/riscv: rvv-1.0: floating-point/integer type-convert instructions
Date: Fri, 26 Feb 2021 11:18:44 +0800 [thread overview]
Message-ID: <20210226031902.23656-61-frank.chang@sifive.com> (raw)
In-Reply-To: <20210226031902.23656-1-frank.chang@sifive.com>
From: Frank Chang <frank.chang@sifive.com>
Add the following instructions:
* vfcvt.rtz.xu.f.v
* vfcvt.rtz.x.f.v
Also adjust GEN_OPFV_TRANS() to accept multiple floating-point rounding
modes.
