This is based on: , the first ISA Manual noting that the 'Zihintntl' extension is ratified. Note that compressed 'Zihintntl' hints require either 'C' or 'Zca' extension. Co-authored-by: Nelson Chu bfd/ChangeLog: * elfxx-riscv.c (riscv_supported_std_z_ext): Add 'Zihintntl' standard hint 'Z' extension. (riscv_multi_subset_supports): Support new instruction classes. (riscv_multi_subset_supports_ext): Likewise. gas/ChangeLog: * testsuite/gas/riscv/zihintntl.s: New test for 'Zihintntl' including auto-compression without C prefix and explicit C prefix. * testsuite/gas/riscv/zihintntl.d: Likewise. * testsuite/gas/riscv/zihintntl-na.d: Likewise. * testsuite/gas/riscv/zihintntl-base.s: New test for correspondence between 'Zihintntl' and base 'I' or 'C' instructions. * testsuite/gas/riscv/zihintntl-base.d: Likewise. include/ChangeLog: * opcode/riscv.h (enum riscv_insn_class): Add new instruction classes: INSN_CLASS_ZIHINTNTL and INSN_CLASS_ZIHINTNTL_AND_C.
