RISC-V: Prefetch hint instructions and operand set
This commit adds 'Zicbop' hint instructions.
bfd/ChangeLog:
* elfxx-riscv.c (riscv_multi_subset_supports): Add handling for
new instruction class.
gas/ChangeLog:
* config/tc-riscv.c (riscv_ip): Add handling for new operand
type 'f' (32-byte aligned pseudo S-type immediate for prefetch
hints).
(validate_riscv_insn): Likewise.
include/ChangeLog:
* opcode/riscv-opc.h (MATCH_PREFETCH_I, MASK_PREFETCH_I,
MATCH_PREFETCH_R, MASK_PREFETCH_R, MATCH_PREFETCH_W,
MASK_PREFETCH_W): New macros.
* opcode/riscv.h (enum riscv_insn_class): Add new instruction
class INSN_CLASS_ZICBOP.
opcodes/ChangeLog:
* riscv-dis.c (print_insn_args): Add handling for new operand
type.
* riscv-opc.c (riscv_opcodes): Add prefetch hint instructions.
