RISC-V: Add support for the Zvbc extension
Zvbc is part of the crypto vector extensions.
This extension adds the following instructions:
- vclmul.[vv,vx]
- vclmulh.[vv,vx]
bfd/ChangeLog:
* elfxx-riscv.c (riscv_multi_subset_supports): Add instruction
class support for Zvbc.
(riscv_multi_subset_supports_ext): Likewise.
gas/ChangeLog:
* testsuite/gas/riscv/zvbc.d: New test.
* testsuite/gas/riscv/zvbc.s: New test.
include/ChangeLog:
* opcode/riscv-opc.h (MATCH_VCLMUL_VV): New.
(MASK_VCLMUL_VV): New.
(MATCH_VCLMUL_VX): New.
(MASK_VCLMUL_VX): New.
(MATCH_VCLMULH_VV): New.
(MASK_VCLMULH_VV): New.
(MATCH_VCLMULH_VX): New.
(MASK_VCLMULH_VX): New.
(DECLARE_INSN): New.
* opcode/riscv.h (enum riscv_insn_class): Add instruction class
support for Zvbc.
opcodes/ChangeLog:
* riscv-opc.c: Add Zvbc instruction.
