[PATCH 04/17] target/riscv: rvv-1.0: Add Zve64f support for vmulh variant insns |

Wed, 29 Dec 2021 10:33:31 +0800 |
From: Frank Chang <frank.chang@sifive.com>
All Zve* extensions support all vector integer instructions,
except that the vmulh integer multiply variants that return the
high word of the product (vmulh.vv, vmulh.vx, vmulhu.vv, vmulhu.vx,
vmulhsu.vv, vmulhsu.vx) are not included for EEW=64 in Zve64*.
