Remove the -mriscv-isa-version and --with-riscv-isa-version options. We can still use -march to choose the version for each extensions, so there is no need to add these. 2. Change the arguments of options from [1p9|1p9p1|...] to [1.9|1.9.1|...]. Unlike the architecture string has specified by spec, ther is no need to do the same thing for options. 3. Spilt the patches to reduce the burdens of review. [PATCH 3/7] RISC-V: Support new GAS options and configure options to set ISA versions to [PATCH v2 3/9] RISC-V: Support GAS option -misa-spec to set ISA versions [PATCH v2 4/9] RISC-V: Support configure options to set ISA versions by default. [PATCH 4/7] RISC-V: Support version checking for CSR according to privilege version. to [PATCH v2 5/9] RISC-V: Support version checking for CSR according to privilege spec version. [PATCH v2 6/9] RISC-V: Support configure option to choose the privilege spec version. 4. Use enum class rather than string to compare the choosen ISA spec in opcodes/riscv-opc.c. The behavior is same as comparing the choosen privilege spec. include * opcode/riscv.h: Include "bfd.h" to support bfd_boolean. (enum riscv_isa_spec_class): New enum class. All supported ISA spec belong to one of the class (struct riscv_ext_version): New structure holds version information for the specific ISA. * opcode/riscv-opc.h (DECLARE_CSR): There are two version information, define_version and abort_version. The define_version means which privilege spec is started to define the CSR, and the abort_version means which privilege spec is started to abort the CSR. If the CSR is valid for the newest spec, then the abort_version should be PRIV_SPEC_CLASS_DRAFT. (DECLARE_CSR_ALIAS): Same as DECLARE_CSR, but only for the obselete CSR. * opcode/riscv.h (enum riscv_priv_spec_class): New enum class. Define the current supported privilege spec versions. (struct riscv_csr_extra): Add new fields to store more information about the CSR. We use these information to find the suitable CSR address when user choosing a specific privilege spec. binutils * dwarf.c: Updated since DECLARE_CSR is changed. opcodes * riscv-opc.c (riscv_ext_version_table): The table used to store all information about the supported spec and the corresponding ISA versions. Currently, only Zicsr is supported to verify the correctness of Z sub extension settings. Others will be supported in the future patches. (struct isa_spec_t, isa_specs): List for all supported ISA spec classes and the corresponding strings. (riscv_get_isa_spec_class): New function. Get the corresponding ISA spec class by giving a ISA spec string. * riscv-opc.c (struct priv_spec_t): New structure. (struct priv_spec_t priv_specs): List for all supported privilege spec classes and the corresponding strings. (riscv_get_priv_spec_class): New function. Get the corresponding privilege spec class by giving a spec string. (riscv_get_priv_spec_name): New function. Get the corresponding privilege spec string by giving a CSR version class. * riscv-dis.c: Updated since DECLARE_CSR is changed. * riscv-dis.c: Add new disassembler option -Mpriv-spec to dump the CSR according to the chosen version. Build a hash table riscv_csr_hash to store the valid CSR for the chosen pirv verison. Dump the direct CSR address rather than it's name if it is invalid. (parse_riscv_dis_option_without_args): New function. Parse the options without arguments. (parse_riscv_dis_option): Call parse_riscv_dis_option_without_args to parse the options without arguments first, and then handle the options with arguments. Add the new option -Mpriv-spec, which has argument. * riscv-dis.c (print_riscv_disassembler_options): Add description about the new OBJDUMP option. ld * testsuite/ld-riscv-elf/attr-merge-arch-01.d: Updated priv attributes according to the -mpriv-spec option. * testsuite/ld-riscv-elf/attr-merge-arch-02.d: Likewise. * testsuite/ld-riscv-elf/attr-merge-arch-03.d: Likewise. * testsuite/ld-riscv-elf/attr-merge-priv-spec-a.s: Likewise. * testsuite/ld-riscv-elf/attr-merge-priv-spec-b.s: Likewise. * testsuite/ld-riscv-elf/attr-merge-priv-spec.d: Likewise. * testsuite/ld-riscv-elf/attr-merge-stack-align.d: Likewise. * testsuite/ld-riscv-elf/attr-merge-strict-align-01.d: Likewise. * testsuite/ld-riscv-elf/attr-merge-strict-align-02.d: Likewise. * testsuite/ld-riscv-elf/attr-merge-strict-align-03.d: Likewise. * testsuite/ld-riscv-elf/attr-merge-strict-align-04.d: Likewise. * testsuite/ld-riscv-elf/attr-merge-strict-align-05.d: Likewise. bfd * elfxx-riscv.h (riscv_parse_subset_t): Add new callback function get_default_version. It is used to find the default version for the specific extension. * elfxx-riscv.c (riscv_parsing_subset_version): Remove the parameters default_major_version and default_minor_version. Add new bfd_boolean parameter *use_default_version. Set it to TRUE if we need to call the callback rps->get_default_version to find the default version. (riscv_parse_std_ext): Call rps->get_default_version if we fail to find the default version in riscv_parsing_subset_version, and then call riscv_add_subset to add the subset into subset list. (riscv_parse_prefixed_ext): Likewise. (riscv_std_z_ext_strtab): Support Zicsr extensions. * elfnn-riscv.c (riscv_merge_std_ext): Use strcasecmp to compare the strings rather than characters. riscv_merge_arch_attr_info): The callback function get_default_version is only needed for assembler, so set it to NULL int the linker. * elfxx-riscv.c (riscv_estimate_digit): Remove the static. * elfxx-riscv.h: Updated. gas * testsuite/gas/riscv/priv-reg-fail-read-only-01.s: Updated. * config/tc-riscv.c (default_arch_with_ext, default_isa_spec): Static variables which are used to set the ISA extensions.

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.

(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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 64-bit version of binutils got support for the PE COFF BIG OBJ format a couple of years ago. The BIG OBJ format is a slightly different COFF format which extends the size of the number of section field in the header from a uint16_t to a uint32_t and so greatly increases the number of sections allowed. However the 32-bit version of bfd never got support for this. The GHC Haskell compiler generates a great deal of symbols due to it's use of -ffunction-sections and -fdata-sections. This meant that we could not build the 32-bit version of the GHC Compiler for many releases now as binutils didn't have this support. This patch adds the support to the 32-bit port of binutils as well and also does come cleanup in the code. bfd/ChangeLog: * coff-i386.c (COFF_WITH_PE_BIGOBJ): New. * coff-x86_64.c (COFF_WITH_PE_BIGOBJ): New. * config.bfd (targ_selvecs): Rename x86_64_pe_be_vec to x86_64_pe_big_vec as it not a big-endian format.

* [AArch64, Binutils] Add missing TSB instructionSudakshina Das2020-04-205-9/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch implements the TSB instructions: https://developer.arm.com/docs/ddi0596/f/base-instructions-alphabetic-order/ tsb-csync-trace-synchronization-barrier Since TSB and PSB both use the same (and only) argument "CSYNC", this patch reuses it for TSB. However, the same argument would imply different value for CRm:Op2 which are anyway fixed values, so I have diverted the inserter/extracter function to dummy versions instead of the "hint" version. The operand checker part still uses the existing infratructure for AARCH64_OPND_BARRIER_PSB to make sure the operand is parsed correctly. gas/ChangeLog: 2020-04-20 Sudakshina Das <sudi.das@arm.com> * config/tc-aarch64.c (parse_barrier_psb): Update error messages to include TSB. * testsuite/gas/aarch64/system-2.d: Update -march and new tsb tests. * testsuite/gas/aarch64/system-2.s: Add new tsb tests. * testsuite/gas/aarch64/system.d: Update. opcodes/ChangeLog: 2020-04-20 Sudakshina Das <sudi.das@arm.com> * aarch64-asm.c (aarch64_ins_none): New. * aarch64-asm.h (ins_none): New declaration. * aarch64-dis.c (aarch64_ext_none): New. * aarch64-dis.h (ext_none): New declaration. * aarch64-opc.c (aarch64_print_operand): Update case for AARCH64_OPND_BARRIER_PSB. * aarch64-tbl.h (aarch64_opcode_table): Add tsb.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are a few instruction in AArch64 that are in the HINT space. Any of these instructions should be accepted by the assembler/disassembler at any architecture version. This patch fixes the existing instructions that are not behaving accordingly. I have used all of the instructions mentioned in the following to make the changes: https://developer.arm.com/docs/ddi0596/f/base-instructions-alphabetic-order/ hint-hint-instruction gas/ChangeLog: 2020-04-20 Sudakshina Das <sudi.das@arm.com> * testsuite/gas/aarch64/bti.d: Update -march option. * testsuite/gas/aarch64/illegal-bti.d: Remove. * testsuite/gas/aarch64/illegal-bti.l: Remove. * testsuite/gas/aarch64/illegal-ras-1.l: Remove esb. * testsuite/gas/aarch64/illegal-ras-1.s: Remove esb. opcodes/ChangeLog: 2020-04-20 Sudakshina Das <sudi.das@arm.com> * aarch64-tbl.h (aarch64_feature_bti, BTI, BTI_INSN): Remove.
