RISC-V: Add support for Zcmop extension
This implements the Zcmop (Compressed Zimop) extension, as of version 1.0.
View detailed information in:
<https://github.com/riscv/riscv-isa-manual/blob/main/src/zimop.adoc>
The Zcmop extension requires the Zca extension.
bfd/ChangeLog:
* elfxx-riscv.c (riscv_multi_subset_supports): Handle Zcmop.
(riscv_multi_subset_supports_ext): Ditto.
gas/ChangeLog:
* NEWS: Updated.
* testsuite/gas/riscv/march-help.l: Ditto.
* testsuite/gas/riscv/zcmop.d: New test.
* testsuite/gas/riscv/zcmop.s: New test.
include/ChangeLog:
* opcode/riscv-opc.h (DECLARE_INSN): New declarations for Zcmop.
(MATCH_C_MOP_1, MATCH_C_MOP_3, MATCH_C_MOP_5, MATCH_C_MOP_7,
MATCH_C_MOP_9, MATCH_C_MOP_11, MATCH_C_MOP_13, MATCH_C_MOP_15): Define.
(MASK_C_MOP_1, MASK_C_MOP_3, MASK_C_MOP_5, MASK_C_MOP_7,
MASK_C_MOP_9, MASK_C_MOP_11, MASK_C_MOP_13, MASK_C_MOP_15): Ditto.
