 351         * testsuite/gas/riscv/priv-reg-fail-read-only-01.s: Updated.
 352         * config/tc-riscv.c (default_arch_with_ext, default_isa_spec):
 353         Static variables which are used to set the ISA extensions. You can
 354         use -march (or ELF build attributes) and -misa-spec to set them,
 355         respectively.
 356         (ext_version_hash): The hash table used to handle the extensions
 357         with versions.
 358         (init_ext_version_hash): Initialize the ext_version_hash according
 359         to riscv_ext_version_table.
 360         (riscv_get_default_ext_version): The callback function of
 361         riscv_parse_subset_t.  According to the choosed ISA spec,
 362         get the default version for the specific extension.
 363         (riscv_set_arch): Set the callback function.
 364         (enum options, struct option md_longopts): Add new option -misa-spec.
 365         (md_parse_option): Do not call riscv_set_arch for -march.  We will
 366         call it later in riscv_after_parse_args.  Call riscv_get_isa_spec_class
 367         to set default_isa_spec class.
 368         (riscv_after_parse_args): Call init_ext_version_hash to initialize the
 369         ext_version_hash, and then call riscv_set_arch to set the architecture
 370         with versions according to default_arch_with_ext.
 371         * testsuite/gas/riscv/attribute-02.d: Set 0p0 as default version for
 372         x extensions.
 373         * testsuite/gas/riscv/attribute-03.d: Likewise.
 374         * testsuite/gas/riscv/attribute-09.d: New testcase.  For i-ext, we
 375         already set it's version to 2p1 by march, so no need to use the default
 376         2p2 version.  For m-ext, we do not set the version by -march and ELF arch
 377         attribute, so set the default 2p0 to it.  For zicsr, it is not defined in
 378         ISA spec 2p2, so set 0p0 to it.
 379         * testsuite/gas/riscv/attribute-10.d: New testcase.  The version of
 380         zicsr is 2p0 according to ISA spec 20191213.
 381         * config/tc-riscv.c (DEFAULT_RISCV_ARCH_WITH_EXT)
 382         (DEFAULT_RISCV_ISA_SPEC): Default configure option settings.
 383         You can set them by configure options --with-arch and
 384         --with-isa-spec, respectively.
 385         (riscv_set_default_isa_spec): New function used to set the
 386         default ISA spec.
 387         (md_parse_option): Call riscv_set_default_isa_spec rather than
 388         call riscv_get_isa_spec_class directly.
 389         (riscv_after_parse_args): If the -isa-spec is not set, then we
 390         set the default ISA spec according to DEFAULT_RISCV_ISA_SPEC by
 391         calling riscv_set_default_isa_spec.
 392         * testsuite/gas/riscv/attribute-01.d: Add -misa-spec=2.2, since
 393         the --with-isa-spec may be set to different ISA spec.
 394         * testsuite/gas/riscv/attribute-02.d: Likewise.

 404         * config/tc-riscv.c (default_priv_spec): Static variable which is
 405         used to check if the CSR is valid for the chosen privilege spec. You
 406         can use -mpriv-spec to set it.
 407         (enum reg_class): We now get the CSR address from csr_extra_hash rather
 408         than reg_names_hash.  Therefore, move RCLASS_CSR behind RCLASS_MAX.
 409         (riscv_init_csr_hashes): Only need to initialize one hash table
 410         csr_extra_hash.
 411         (riscv_csr_class_check): Change the return type to void.  Don't check
 412         the ISA dependency if -mcsr-check isn't set.
 413         (riscv_csr_version_check): New function.  Check and find the CSR address
 414         from csr_extra_hash, according to default_priv_spec.  Report warning
 415         for the invalid CSR if -mcsr-check is set.

 420         (md_parse_option): Call riscv_set_default_priv_version to set
 421         default_priv_spec.

 423         privilege spec to the newest one.
 424         (enum riscv_csr_class, struct riscv_csr_extra): Move them to
 425         include/opcode/riscv.h.
 426         * testsuite/gas/riscv/priv-reg-fail-fext.d: This test case just want
 427         to check the ISA dependency for CSR, so fix the spec version by adding
 428         -mpriv-spec=1.11.
