[PATCH v2 09/17] target/riscv: Add Zvbb ISA extension support |
|
Date: |
Mon, 17 Apr 2023 14:58:13 +0100 |
From: Dickon Hood <dickon.hood@codethink.co.uk>
This commit adds support for the Zvbc vector-crypto extension, which
consists of the following instructions:
* vrol.[vv,vx]
* vror.[vv,vx,vi]
* vbrev8.v
* vrev8.v
* vandn.[vv,vx]
* vbrev.v
* vclz.v
* vctz.v
* vcpop.v
* vswll.[vv,vx,vi]
Translation functions are defined in
`target/riscv/insn_trans/trans_rvvk.c.inc` and helpers are defined in
`target/riscv/vcrypto_helper.c`.
