[PATCH v3 00/19] Add RISC-V vector cryptographic instruction set support

[Lawrence Hunter]

This patchset provides an implementation for Zvbb, Zvbc, Zvkned, Zvknh, Zvksh, 
Zvkg, and Zvksed of the draft RISC-V vector cryptography extensions as per the 
v20230425 version of the specification(1) (6a7ae7f2). This is an update to the 
patchset submitted to qemu-devel on Monday, 17 Apr 2023 14:58:36 +0100.

v2:

    squashed commits into one commit per extension with separate commits for
    each refactoring
    unified trans_rvzvk*.c.inc files into one trans_rvvk.c.inc
    style fixes in insn32.decode and other files
    added macros for EGS values in translation functions.
    updated from v20230303 to v20230407 of the spec:
        Zvkb has been split into Zvbb and Zvbc
        vbrev, vclz, vctz, vcpop and vwsll have been added to Zvbb.

v3:

    New patch 03/19 removes redundant “cpu_vl == 0” checks from trans_rvv.c.inc
    Introduction of new tcg ops has been factored out of patch 11/19 and into 
09/19
        These ops are now added to non riscv-specific files

As v20230425 is a freeze candidate, we are not expecting any significant 
changes to the specification or this patch series.

Please note that the Zvkt data-independent execution latency extension (and all 
extensions including it) has not been implemented, and we would recommend not 
using these patches in an environment where timing attacks are an issue.

Work performed by Dickon, Lawrence, Nazar, Kiran, and William from Codethink 
sponsored by SiFive, as well as Max Chou and Frank Chang from SiFive.

For convenience we have created a git repo with our patches on top of a recent 
master. https://github.com/CodethinkLabs/qemu-ct
