RISC-V: Scalar crypto instructions and operand set.
Add instructions in k-ext, some instruction in zbkb, zbkc is reuse from zbb,zbc, we just change the class attribute to make them both support. The 'aes64ks1i' and 'aes64ks2' instructions are present in both the Zknd and Zkne extensions on rv64. Add new operand letter 'y' to present 'bs' symbol and 'Y' to present 'rnum' symbolc for zkn instructions. Also add a new Entropy Source CSR define 'seed' located at address 0x015. bfd/ * elfxx-riscv.c (riscv_multi_subset_supports): Added support for crypto extension. gas/ *config/tc-riscv.c (enum riscv_csr_class): Added CSR_CLASS_ZKR. (riscv_csr_address): Checked for CSR_CLASS_ZKR. (validate_riscv_insn): Added y and Y for bs and rnum operands. (riscv_ip): Handle y and Y operands. include/ * opcode/riscv-opc.h: Added encodings of crypto instructions. Also defined new csr seed, which address is 0x15. * opcode/riscv.h: Defined OP_* and INSN_CLASS_* for crypto. opcodes/ * riscv-dis.c (print_insn_args): Recognized new y and Y operands. * riscv-opc.c (riscv_opcodes): Added crypto instructions.
