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

 392         --with-isa-spec.
 393         * configure: Regenerated.
 394         * config.in: Regenerated.
 395         * config/tc-riscv.c (default_priv_spec): Static variable which is
 396         used to check if the CSR is valid for the chosen privilege spec. You
 397         can use -mpriv-spec to set it.
 398         (enum reg_class): We now get the CSR address from csr_extra_hash rather
 399         than reg_names_hash.  Therefore, move RCLASS_CSR behind RCLASS_MAX.
 400         (riscv_init_csr_hashes): Only need to initialize one hash table
 401         csr_extra_hash.
 402         (riscv_csr_class_check): Change the return type to void.  Don't check
 403         the ISA dependency if -mcsr-check isn't set.
 404         (riscv_csr_version_check): New function.  Check and find the CSR address
 405         from csr_extra_hash, according to default_priv_spec.  Report warning
 406         for the invalid CSR if -mcsr-check is set.
 407         (reg_csr_lookup_internal): Updated.
 408         (reg_lookup_internal): Likewise.
 409         (md_begin): Updated since DECLARE_CSR and DECLARE_CSR_ALIAS are changed.
 410         (enum options, struct option md_longopts): Add new GAS option -mpriv-spec.
 411         (md_parse_option): Call riscv_set_default_priv_version to set
 412         default_priv_spec.
 413         (riscv_after_parse_args): If -mpriv-spec isn't set, then set the default
 414         privilege spec to the newest one.
 415         (enum riscv_csr_class, struct riscv_csr_extra): Move them to
 416         include/opcode/riscv.h.
 417         * testsuite/gas/riscv/priv-reg-fail-fext.d: This test case just want
 418         to check the ISA dependency for CSR, so fix the spec version by adding
 419         -mpriv-spec=1.11.
 420         * testsuite/gas/riscv/priv-reg-fail-fext.l: Likewise.  There are some

 439         * config/tc-riscv.c (DEFAULT_RISCV_ISA_SPEC): Default configure option
 440         setting.  You can set it by configure option --with-priv-spec.
 441         (riscv_set_default_priv_spec): New function used to set the default
 442         privilege spec.
 443         (md_parse_option): Call riscv_set_default_priv_spec rather than
 444         call riscv_get_priv_spec_class directly.
 445         (riscv_after_parse_args): If -mpriv-spec isn't set, then we set the
 446         default privilege spec according to DEFAULT_RISCV_PRIV_SPEC by
 447         calling riscv_set_default_priv_spec.
 448         * testsuite/gas/riscv/csr-dw-regnums.d: Add -mpriv-spec=1.11, since

 457         the priv attributes are set.
 458         (md_assemble): Set the default_priv_spec according to the priv
 459         attributes when we start to assemble instruction.
 460         (riscv_write_out_attrs): Rename riscv_write_out_arch_attr to
 461         riscv_write_out_attrs.  Update the arch and priv attributes.  If we
 462         don't set the corresponding ELF attributes, then try to output the
 463         default ones.
 464         (riscv_set_public_attributes): If any ELF attribute or -march-attr
 465         options is set (explicit_attr is TRUE), then call riscv_write_out_attrs
 466         to update the arch and priv attributes.
