Subject: [PATCH v2 04/14] target/riscv: Replace Zvbb checking by Zvkb
Date: Thu, 26 Oct 2023 23:18:11 +0800	[thread overview]
Message-ID: <20231026151828.754279-5-max.chou@sifive.com> (raw)
In-Reply-To: <20231026151828.754279-1-max.chou@sifive.com>

The Zvkb extension is a proper subset of the Zvbb extension and includes
following instructions:
  * vandn.[vv,vx]
  * vbrev8.v
  * vrev8.v
  * vrol.[vv,vx]
  * vror.[vv,vx,vi]
