RISC-V: Allow instruction require more than one extension
2018-08-29 Kito Cheng <kito@andestech.com> gas/ * config/tc-riscv.c (riscv_subset_supports): New argument: xlen_required. (riscv_multi_subset_supports): New function, able to check more than one extension. (riscv_ip): Use riscv_multi_subset_supports instead of riscv_subset_supports. (riscv_set_arch): Update call-site for riscv_subset_supports. (riscv_after_parse_args): Likewise. include/ *opcode/riscv.h (MAX_SUBSET_NUM): New. (riscv_opcode): Add xlen_requirement field and change type of subset. opcodes/ * riscv-dis.c (riscv_disassemble_insn): Check XLEN by riscv_opcode.xlen_requirement. * riscv-opc.c (riscv_opcodes): Update for struct change.
