From 434c609bef445e0dd13d514c5b12f8e47a73cd1d Mon Sep 17 00:00:00 2001 From: Max Chou Date: Thu, 26 Oct 2023 23:18:19 +0800 Subject: [PATCH] disas/riscv: Add rv_codec_vror_vi for vror.vi Add rv_codec_vror_vi for the vector crypto instruction - vror.vi. The rotate amount of vror.vi is defined by combining seperated bits.
