 638         * testsuite/gas/riscv/priv-reg-fail-read-only-01.s: Updated.
 639         * config/tc-riscv.c (default_arch_with_ext, default_isa_spec):
 640         Static variables which are used to set the ISA extensions. You can
 641         use -march (or ELF build attributes) and -misa-spec to set them,
 642         respectively.
 643         (ext_version_hash): The hash table used to handle the extensions
 644         with versions.
 645         (init_ext_version_hash): Initialize the ext_version_hash according
 646         to riscv_ext_version_table.
 647         (riscv_get_default_ext_version): The callback function of
 648         riscv_parse_subset_t.  According to the choosed ISA spec,
 649         get the default version for the specific extension.
 650         (riscv_set_arch): Set the callback function.
 651         (enum options, struct option md_longopts): Add new option -misa-spec.
 652         (md_parse_option): Do not call riscv_set_arch for -march.  We will
 653         call it later in riscv_after_parse_args.  Call riscv_get_isa_spec_class
 654         to set default_isa_spec class.
 655         (riscv_after_parse_args): Call init_ext_version_hash to initialize the
 656         ext_version_hash, and then call riscv_set_arch to set the architecture
 657         with versions according to default_arch_with_ext.
 658         * testsuite/gas/riscv/attribute-02.d: Set 0p0 as default version for
 659         x extensions.
 660         * testsuite/gas/riscv/attribute-03.d: Likewise.
 661         * testsuite/gas/riscv/attribute-09.d: New testcase.  For i-ext, we
 662         already set it's version to 2p1 by march, so no need to use the default
 663         2p2 version.  For m-ext, we do not set the version by -march and ELF arch
 664         attribute, so set the default 2p0 to it.  For zicsr, it is not defined in
 665         ISA spec 2p2, so set 0p0 to it.
 666         * testsuite/gas/riscv/attribute-10.d: New testcase.  The version of
 667         zicsr is 2p0 according to ISA spec 20191213.
 668         * config/tc-riscv.c (DEFAULT_RISCV_ARCH_WITH_EXT)
 669         (DEFAULT_RISCV_ISA_SPEC): Default configure option settings.
 670         You can set them by configure options --with-arch and
 671         --with-isa-spec, respectively.
 672         (riscv_set_default_isa_spec): New function used to set the
 673         default ISA spec.
 674         (md_parse_option): Call riscv_set_default_isa_spec rather than
 675         call riscv_get_isa_spec_class directly.
 676         (riscv_after_parse_args): If the -isa-spec is not set, then we
 677         set the default ISA spec according to DEFAULT_RISCV_ISA_SPEC by
 678         calling riscv_set_default_isa_spec.
 679         * testsuite/gas/riscv/attribute-01.d: Add -misa-spec=2.2, since
 680         the --with-isa-spec may be set to different ISA spec.
 681         * testsuite/gas/riscv/attribute-02.d: Likewise.

 690         * config.in: Regenerated.
 691         * config/tc-riscv.c (default_priv_spec): Static variable which is
 692         used to check if the CSR is valid for the chosen privilege spec. You
 693         can use -mpriv-spec to set it.
 694         (enum reg_class): We now get the CSR address from csr_extra_hash rather
 695         than reg_names_hash.  Therefore, move RCLASS_CSR behind RCLASS_MAX.
 696         (riscv_init_csr_hashes): Only need to initialize one hash table
 697         csr_extra_hash.
 698         (riscv_csr_class_check): Change the return type to void.  Don't check
 699         the ISA dependency if -mcsr-check isn't set.
 700         (riscv_csr_version_check): New function.  Check and find the CSR address
 701         from csr_extra_hash, according to default_priv_spec.  Report warning
 702         for the invalid CSR if -mcsr-check is set.
 703         (reg_csr_lookup_internal): Updated.
 704         (reg_lookup_internal): Likewise.
 705         (md_begin): Updated since DECLARE_CSR and DECLARE_CSR_ALIAS are changed.
 706         (enum options, struct option md_longopts): Add new GAS option -mpriv-spec.
 707         (md_parse_option): Call riscv_set_default_priv_version to set
 708         default_priv_spec.
 709         (riscv_after_parse_args): If -mpriv-spec isn't set, then set the default
 710         privilege spec to the newest one.
 711         (enum riscv_csr_class, struct riscv_csr_extra): Move them to
 712         include/opcode/riscv.h.
 713         * testsuite/gas/riscv/priv-reg-fail-fext.d: This test case just want
 714         to check the ISA dependency for CSR, so fix the spec version by adding
 715         -mpriv-spec=1.11.
 716         * testsuite/gas/riscv/priv-reg-fail-fext.l: Likewise.  There are some

 738         privilege spec.

 743         calling riscv_set_default_priv_spec.
 744         * testsuite/gas/riscv/csr-dw-regnums.d: Add -mpriv-spec=1.11, since
