From: Lifang Xia <lifang_xia@c-sky.com>
Add CSRs and opcodes of the XUANTIE CPUs, extensions named "theadc",
"xtheade" and "xtheadse".
bfd/ChangeLog
* cpu-riscv.h (riscv_spec_class) <VENDOR_SPEC_CLASS_THEAD>: New
value.
* elfxx-riscv.c (riscv_supported_custom_ext): New table.
(riscv_all_supported_ext): Add riscv_supported_custom_ext.
(riscv_recognized_prefixed_ext): Update comment.
(riscv_get_default_ext_version): Add the t-head extensions.
(riscv_multi_subset_supports): Likewise.
(riscv_multi_subset_supports_ext): Likewise.
gas/ChangeLog
* config/tc-riscv.c (riscv_csr_class) <CSR_CLASS_THEAD>: New
value.
(riscv_csr_address): Add CSR_CLASS_THEAD.
(validate_riscv_insn): Add the XI and XS formats.
(riscv_ip): Likewise.
gas/testsuite/ChangeLog
* gas/riscv/thead-csr-list.d: New test.
* gas/riscv/theadc-ext.d: Likewise.
* gas/riscv/theadc-ext.s: Likewise.
* gas/riscv/theade-ext.d: Likewise.
* gas/riscv/theade-ext.s: Likewise.
include/ChangeLog
* opcode/iscv-opc-thead.h: New file.
opcodes/ChangeLog
* riscv-dis.c (print_insn_args): Support XI and XS formats.
* riscv-opc.c (match_thead_rd1_rd2_neq_rs1): New function.
(riscv_opcodes): Add the t-thead extensions.

I cherry-picked this off Nelson's integration branch at sourceware, and
then went through it a bit to avoid the dependencies on the experimental
extension handling (and also just some cleanups). This should be
functionally the same as what was originally posted, aside from having
the "th." prefix on instructions and the "th_" prefix on CSRs.
This passes the tests, but I don't currently have any other way to
verify it.

Hi Palmer
They are trying to reorg the structure of their extensions as I know,
so the extension name might be obsolete now?
https://github.com/riscv-non-isa/riscv-toolchain-conventions/pull/19
Hi Jojo, Li-Fan:
Could you confirm that?
Thanks

Hi Kito & Palmer,
Thanks for this patch.
We are implementing the opcodes following this PR. And there are some
diffecerences about the ISA string.
If you want do some tests about the instructions, this patch is OK.
Thanks,
Lifang
