You can + use -march (or ELF build attributes) and -misa-spec to set them, + respectively. + (ext_version_hash): The hash table used to handle the extensions + with versions. + (init_ext_version_hash): Initialize the ext_version_hash according + to riscv_ext_version_table. + (riscv_get_default_ext_version): The callback function of + riscv_parse_subset_t. According to the choosed ISA spec, + get the default version for the specific extension. + (riscv_set_arch): Set the callback function. + (enum options, struct option md_longopts): Add new option -misa-spec. + (md_parse_option): Do not call riscv_set_arch for -march. We will + call it later in riscv_after_parse_args. Call riscv_get_isa_spec_class + to set default_isa_spec class. + (riscv_after_parse_args): Call init_ext_version_hash to initialize the + ext_version_hash, and then call riscv_set_arch to set the architecture + with versions according to default_arch_with_ext. + * testsuite/gas/riscv/attribute-02.d: Set 0p0 as default version for + x extensions. + * testsuite/gas/riscv/attribute-03.d: Likewise. + * testsuite/gas/riscv/attribute-09.d: New testcase. For i-ext, we + already set it's version to 2p1 by march, so no need to use the default + 2p2 version. For m-ext, we do not set the version by -march and ELF arch + attribute, so set the default 2p0 to it. For zicsr, it is not defined in + ISA spec 2p2, so set 0p0 to it. + * testsuite/gas/riscv/attribute-10.d: New testcase. The version of + zicsr is 2p0 according to ISA spec 20191213. + * config/tc-riscv.c (DEFAULT_RISCV_ARCH_WITH_EXT) + (DEFAULT_RISCV_ISA_SPEC): Default configure option settings. + You can set them by configure options --with-arch and + --with-isa-spec, respectively. + (riscv_set_default_isa_spec): New function used to set the + default ISA spec. + (md_parse_option): Call riscv_set_default_isa_spec rather than + call riscv_get_isa_spec_class directly. + (riscv_after_parse_args): If the -isa-spec is not set, then we + set the default ISA spec according to DEFAULT_RISCV_ISA_SPEC by + calling riscv_set_default_isa_spec. + * testsuite/gas/riscv/attribute-01.d: Add -misa-spec=2.2, since + the --with-isa-spec may be set to different ISA spec. + * testsuite/gas/riscv/attribute-02.d: Likewise. + * testsuite/gas/riscv/attribute-03.d: Likewise. + * testsuite/gas/riscv/attribute-04.d: Likewise. + * testsuite/gas/riscv/attribute-05.d: Likewise. + * testsuite/gas/riscv/attribute-06.d: Likewise. + * testsuite/gas/riscv/attribute-07.d: Likewise. + * configure.ac: Add configure options, --with-arch and + --with-isa-spec. + * configure: Regenerated. + * config.in: Regenerated. + * config/tc-riscv.c (default_priv_spec): Static variable which is + used to check if the CSR is valid for the chosen privilege spec. You + can use -mpriv-spec to set it. + (enum reg_class): We now get the CSR address from csr_extra_hash rather + than reg_names_hash. Therefore, move RCLASS_CSR behind RCLASS_MAX. + (riscv_init_csr_hashes): Only need to initialize one hash table + csr_extra_hash. + (riscv_csr_class_check): Change the return type to void. Don't check + the ISA dependency if -mcsr-check isn't set. + (riscv_csr_version_check): New function. Check and find the CSR address + from csr_extra_hash, according to default_priv_spec. Report warning + for the invalid CSR if -mcsr-check is set. + (reg_csr_lookup_internal): Updated. + (reg_lookup_internal): Likewise. + (md_begin): Updated since DECLARE_CSR and DECLARE_CSR_ALIAS are changed. + (enum options, struct option md_longopts): Add new GAS option -mpriv-spec. + (md_parse_option): Call riscv_set_default_priv_version to set + default_priv_spec. + (riscv_after_parse_args): If -mpriv-spec isn't set, then set the default + privilege spec to the newest one. + (enum riscv_csr_class, struct riscv_csr_extra): Move them to + include/opcode/riscv.h. + * testsuite/gas/riscv/priv-reg-fail-fext.d: This test case just want + to check the ISA dependency for CSR, so fix the spec version by adding + -mpriv-spec=1.11. + * testsuite/gas/riscv/priv-reg-fail-fext.l: Likewise. There are some + version warnings for the test case. + * gas/testsuite/gas/riscv/priv-reg-fail-read-only-01.d: Likewise. + * gas/testsuite/gas/riscv/priv-reg-fail-read-only-01.l: Likewise. + * gas/testsuite/gas/riscv/priv-reg-fail-read-only-02.d: Likewise. + * gas/testsuite/gas/riscv/priv-reg-fail-rv32-only.d: Likewise. + * gas/testsuite/gas/riscv/priv-reg-fail-rv32-only.l: Likewise. + * gas/testsuite/gas/riscv/priv-reg-fail-version-1p9.d: New test case. + Check whether the CSR is valid when privilege version 1.9 is choosed. + * gas/testsuite/gas/riscv/priv-reg-fail-version-1p9.l: Likewise. + * gas/testsuite/gas/riscv/priv-reg-fail-version-1p9p1.d: New test case. + Check whether the CSR is valid when privilege version 1.9.1 is choosed. + * gas/testsuite/gas/riscv/priv-reg-fail-version-1p9p1.l: Likewise. + * gas/testsuite/gas/riscv/priv-reg-fail-version-1p10.d: New test case. + Check whether the CSR is valid when privilege version 1.10 is choosed. + * gas/testsuite/gas/riscv/priv-reg-fail-version-1p10.l: Likewise. + * gas/testsuite/gas/riscv/priv-reg-fail-version-1p11.d: New test case. + Check whether the CSR is valid when privilege version 1.11 is choosed. + * gas/testsuite/gas/riscv/priv-reg-fail-version-1p11.l: Likewise. + * config/tc-riscv.c (DEFAULT_RISCV_ISA_SPEC): Default configure option + setting.
