bfd/ChangeLog:
* elfxx-riscv.c (riscv_multi_subset_supports): Add `xcvbitmanip`
instruction class.
(riscv_multi_subset_supports_ext): Likewise.
gas/ChangeLog:
* config/tc-riscv.c (validate_riscv_insn): Add custom operands `Xc6` and `Xc7`.
(riscv_ip): Likewise.
* doc/c-riscv.texi: Note XCVbitmanip as an additional ISA extension
for CORE-V.
* testsuite/gas/riscv/march-help.l: Add xcvbitmanip.
* testsuite/gas/riscv/x-cv-bitmanip-fail.d: New Test.
* testsuite/gas/riscv/x-cv-bitmanip-fail.l: New Test.
* testsuite/gas/riscv/x-cv-bitmanip-fail.s: New Test.
* testsuite/gas/riscv/x-cv-bitmanip.d: New Test.
* testsuite/gas/riscv/x-cv-bitmanip.s: New Test.
include/opcode/ChangeLog:
* riscv-opc.h: Add corresponding MATCH and MASK macros for
XCVbitmanip.
* riscv.h: Add corresponding EXTRACT and ENCODE macros for
XCVbitmanip.
(enum riscv_insn_class): Add the XCVbitmanip instruction class.
opcodes/ChangeLog:
* riscv-dis.c (print_insn_args): Add custom operands `Xc6` and `Xc7`.
* riscv-opc.c: Add XCvBitmanip instructions.
