[PATCH 05/17] target/riscv: rvv-1.0: Add Zve64f support for vsmul.vv and vsmul.vx insns |
|
Date: |
Wed, 29 Dec 2021 10:33:32 +0800 |
From: Frank Chang <frank.chang@sifive.com>
All Zve* extensions support all vector fixed-point arithmetic
instructions, except that vsmul.vv and vsmul.vx are not supported
for EEW=64 in Zve64*.
