RISC-V: Add support for the 'Zihintntl' extension
This commit adds 'Zihintntl' extension and its hint instructions.
This is based on:
<https://github.com/riscv/riscv-isa-manual/commit/0dc91f505e6da7791d5a733c553e6e2506ddcab5>,
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 <nelson@rivosinc.com>
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.
(MASK_NTL_P1, MATCH_NTL_P1, MASK_NTL_PALL,
MATCH_NTL_PALL, MASK_NTL_S1, MATCH_NTL_S1, MASK_NTL_ALL,
MATCH_NTL_ALL, MASK_C_NTL_P1, MATCH_C_NTL_P1, MASK_C_NTL_PALL,
MATCH_C_NTL_PALL, MASK_C_NTL_S1, MATCH_C_NTL_S1, MASK_C_NTL_ALL,
MATCH_C_NTL_ALL): New.
opcodes/ChangeLog:
* riscv-opc.c (riscv_opcodes): Add instructions from the
'Zihintntl' extension.
