commit 9d469329d229da8e2a6d7b70a2be3988aa45a277
Author: Christoph Müllner <christoph.muellner@vrull.eu>
Date: Fri Jun 30 22:43:46 2023 +0200
RISC-V: Add support for the Zvkg ISA extension
Zvkg is part of the vector crypto extensions.
This extension adds the following instructions:
- vghsh.vv
- vgmul.vv
bfd/ChangeLog:
* elfxx-riscv.c (riscv_multi_subset_supports): Add instruction
class support for Zvkg.
(riscv_multi_subset_supports_ext): Likewise.
gas/ChangeLog:
* testsuite/gas/riscv/zvkg.d: New test.
* testsuite/gas/riscv/zvkg.s: New test.
include/ChangeLog:
* opcode/riscv-opc.h (MATCH_VGHSH_VV): New.
(MASK_VGHSH_VV): New.
(MATCH_VGMUL_VV): New.
(MASK_VGMUL_VV): New.
(DECLARE_INSN): New.
* opcode/riscv.h (enum riscv_insn_class): Add instruction class
support for Zvkg.
opcodes/ChangeLog:
* riscv-opc.c: Add Zvkg instructions.
