(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. --- opcodes/riscv-dis.c | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'opcodes/riscv-dis.c') diff --git a/opcodes/riscv-dis.c b/opcodes/riscv-dis.c index 34724d4aec5..57b798d8e14 100644 --- a/opcodes/riscv-dis.c +++ b/opcodes/riscv-dis.c @@ -424,6 +424,10 @@ print_insn_args (const char *oparg, insn_t l, bfd_vma pc, disassemble_info *info print (info->stream, "%d", (int)EXTRACT_STYPE_IMM (l)); break; + case 'f': + print (info->stream, "%d", (int)EXTRACT_STYPE_IMM (l)); + break; + case 'a': info->target = EXTRACT_JTYPE_IMM (l) + pc; (*info->print_address_func) (info->target, info); -- cgit v1.2.1
