UNRATIFIED RISC-V: Add 'Zimop' extension
[DO NOT MERGE] Until the 'Zimop' extension is frozen/ratified and final version number is determined, this patch should not be merged upstream. This commit uses version 0.1 as a placeholder. This commit adds support for "May Be Operations (MOP)" (Zimop) extension which adds 32 2-operand MOP instructions and 8 3-operand MOP instructions. By default, they are practically the same as "li rd, 0". However, if certain feature is supported (and optionally enabled), it is allowed to alter architectural state unlike HINT instructions. This commit is based on the TENTATIVE specification: <riscv/riscv-cfi#131> bfd/ChangeLog: * elfxx-riscv.c (riscv_supported_std_z_ext): Add 'Zimop'. (riscv_multi_subset_supports): Support new instruction class. (riscv_multi_subset_supports_ext): Likewise. gas/ChangeLog: * testsuite/gas/riscv/zimop.s: New test for 'Zimop'. * testsuite/gas/riscv/zimop.d: Likewise. * testsuite/gas/riscv/zimop-noarch.d: New test for architecture failure. * testsuite/gas/riscv/zimop-noarch.l: Likewise. include/ChangeLog: * opcode/riscv-opc.h (MATCH_MOP_R_0, MASK_MOP_R_0, MATCH_MOP_R_1, MASK_MOP_R_1, MATCH_MOP_R_2, MASK_MOP_R_2, MATCH_MOP_R_3, MASK_MOP_R_3, MATCH_MOP_R_4, MASK_MOP_R_4, MATCH_MOP_R_5, MASK_MOP_R_5, MATCH_MOP_R_6, MASK_MOP_R_6, MATCH_MOP_R_7, MASK_MOP_R_7, MATCH_MOP_R_8, MASK_MOP_R_8, MATCH_MOP_R_9, MASK_MOP_R_9, MATCH_MOP_R_10, MASK_MOP_R_10, MATCH_MOP_R_11, MASK_MOP_R_11, MATCH_MOP_R_12, MASK_MOP_R_12, MATCH_MOP_R_13, MASK_MOP_R_13, MATCH_MOP_R_14, MASK_MOP_R_14, MATCH_MOP_R_15, MASK_MOP_R_15, MATCH_MOP_R_16, MASK_MOP_R_16, MATCH_MOP_R_17, MASK_MOP_R_17, MATCH_MOP_R_18, MASK_MOP_R_18, MATCH_MOP_R_19, MASK_MOP_R_19, MATCH_MOP_R_20, MASK_MOP_R_20, MATCH_MOP_R_21, MASK_MOP_R_21, MATCH_MOP_R_22, MASK_MOP_R_22, MATCH_MOP_R_23, MASK_MOP_R_23, MATCH_MOP_R_24, MASK_MOP_R_24, MATCH_MOP_R_25, MASK_MOP_R_25, MATCH_MOP_R_26, MASK_MOP_R_26, MATCH_MOP_R_27, MASK_MOP_R_27, MATCH_MOP_R_28, MASK_MOP_R_28, MATCH_MOP_R_29, MASK_MOP_R_29, MATCH_MOP_R_30, MASK_MOP_R_30, MATCH_MOP_R_31, MASK_MOP_R_31, MATCH_MOP_RR_0, MASK_MOP_RR_0, MATCH_MOP_RR_1, MASK_MOP_RR_1, MATCH_MOP_RR_2, MASK_MOP_RR_2, MATCH_MOP_RR_3, MASK_MOP_RR_3, MATCH_MOP_RR_4, MASK_MOP_RR_4, MATCH_MOP_RR_5, MASK_MOP_RR_5, MATCH_MOP_RR_6, MASK_MOP_RR_6, MATCH_MOP_RR_7, MASK_MOP_RR_7): New. * opcode/riscv.h (enum riscv_insn_class): Add new instruction class INSN_CLASS_ZIMOP. opcodes/ChangeLog: * riscv-opc.c (riscv_opcodes): Add new "may be" operations from the 'Zimop' extension near the bottom.
