2020-05-21Re: PR25993, read of freed memoryAlan Modra2-0/+34
git commit 7b958a48e132 put the bfd filename in the bfd objalloc memory. That means the filename is freed by _bfd_free_cached_info. Which is called by _bfd_compute_and_write_armap to tidy up symbol tables after they are done with. Unfortunately, _bfd_write_archive_contents wants to seek and read from archive elements after that point, and if the number of elements exceeds max_open_files in cache.c then some of those elements will have their files closed. To reopen, you need the filename. PR 25993 * opncls.c (_bfd_free_cached_info): Keep a copy of the bfd filename. (_bfd_delete_bfd): Free the copy. (_bfd_new_bfd): Free nbfd->memory on error.

2020-05-20[PATCH v2 0/9] RISC-V: Support version controling for ISA standard ↵Nelson Chu5-1575/+1858
extensions and CSR 1. 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.

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. 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.

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.

2020-05-19[PATCH v3] aarch64: Emit jump slot for conditional branch to undefined symbolsSiddhesh Poyarekar2-4/+25
The linker silently writes out a conditional branch to 0 if the target symbol in R_AARCH64_CONDBR19 or R_AARCH64_TSTBR14 relocations is undefined. Emit a PLT instead so that behaviour is the same for these relocations as the llvm linker. The special behaviour for undefined weak symbols, where conditional branches to such symbols result in a branch unto themselves, has been retained.

2020-05-18ECOFF slurp_relocs thinkoAlan Modra2-3/+8
In git commit 806470a219 I swapped the order of internal vs. external relocs memory allocation in ecoff_slurp_reloc_table, the idea being that the external reloc size can be sanity checked against file size. However, that fails badly with bfd_alloc memory where releasing any block also releases all more recently allocated blocks. * ecoff.c (ecoff_slurp_reloc_table): Malloc external_relocs so they can be freed without also freeing internal_relocs.

2020-05-14RISC-V: Add elfNN_riscv_mkobject to initialize RISC-V tdata.Nelson Chu2-0/+14
For now we only have one char pointer in RISC-V tdata, so it should be fine. But once we need more elements in tdata, then we may get some uninitialize or unexpected values. I do meet the same problem when extending the RISC-V tdata. bfd/ elfnn-riscv.c (elfNN_riscv_mkobject): New function. We need this to initialize RISC-V tdata.
