Instead,the 64-bit 'r_info' field is really a 32-bit symbol index followed by fourindividual byte type fields. For big-endian MIPS64, treating this as a64-bit integer happens to be compatible with the layout expected by otherarchitectures (symbol index in upper 32-bits of resulting "native" 64-bitinteger). However, for little-endian MIPS64 the parsed 64-bit integercontains the symbol index in the low 32 bits and the 4 individual bytetype fields in the upper 32-bits (but as if the upper 32-bits werebyte-swapped).To cope, add two helper routines in gelf_getrel.c to translate between thecorrect native 'r_info' value and the value obtained after the normalbyte-swap translation. Use these routines in gelf_getrel(), gelf_getrela(),gelf_update_rel(), and gelf_update_rela(). This fixes 'readelf -r' onlittle-endian MIPS64 objects which was previously decoding incorrectrelocations as well as 'objcopy: invalid symbox index' warnings fromobjcopy when extracting debug symbols from kernel modules.Even with this fixed, objcopy was still crashing when trying to extractdebug symbols from little-endian MIPS64 modules. The workaround ingelf_*rel*() depends on the current ELF object having a valid ELF headerso that the 'e_machine' field can be compared against EM_MIPS. objcopywas parsing the relocation entries to possibly rewrite the 'r_info' fieldsin the update_relocs() function before writing the initial ELF header tothe destination object file. Move the initial write of the ELF headerearlier before copy_contents() so that update_relocs() uses the correctsymbol index values.Note that this change should really go upstream. The binutils readelfsource has a similar hack for MIPS64EL though I implemented this versionfrom scratch using the MIPS64 ABI PDF as a reference.Discussed with: jkoshyReviewed by: emaste, impApproved by: re (gjb, kib)MFC after: 1 monthDifferential Revision: https://reviews.freebsd.org/D15734 List of files: /src/contrib/elftoolchain/libelf/Makefile Wed, 05 Sep 2018 20:51:53 +0000 John Baldwin <jhb@FreeBSD.org> http://opengrok.net:8080/history/src/contrib/elftoolchain/libelf/Makefile#ae500c1ff8974130f7f2692772cf288b90349e0d Update to ELF Tool Chain r3668Highlights:- Make sure that only TLS sections are sorted into TLS segment.- Fixed multiple errors in "Section to Segment mapping".- Man page updates- ar improvements- elfcopy: avoid filter_reloc uninitialized variable for rela- elfcopy: avoid stripping relocations from static binaries- readelf: avoid printing directory in front of absolute path- readelf: add NT_FREEBSD_FEATURE_CTL FreeBSD note type- test improvementsNOTES:Some of these changes originated in FreeBSD and simply reduce diffsbetween contrib and vendor.ELF Tool Chain ar is not (currently) used in FreeBSD, and there areimprovements in both FreeBSD and ELF Tool Chain ar that are not inthe other.Sponsored by: The FreeBSD Foundation List of files: /src/contrib/elftoolchain/libelf/Makefile Thu, 10 Jan 2019 14:35:23 +0000 Ed Maste <emaste@FreeBSD.org> http://opengrok.net:8080/history/src/contrib/elftoolchain/libelf/Makefile#3af64f03119a159ac15eb75b92d346705b490385 Merge ^/head r338392 through r338594.

Convert ctfconvert touse the APIs from the new libdwarf and make ctfconvert work with Clang3.4.__FreeBSD_version is bumped to 1100006.A list of notable changes:[libelf]* The old libelf source code in lib/libelf has been removed. Instead, the new libelf is built from contrib/elftoolchain/libelf.* Manual pages are largely improved.* Internal implementation was refactored and improved for better correctness and portability.* Fixed a few memory leaks.* Extended with extension APIs `elf_open()` and `elf_openmemory()`. These APIs are similar to `elf_begin()` and `elf_memory()` respectively, except that they return an ELF descriptor of kind `ELF_K_NONE` instead of an error if the object being opened could not be parsed.* Implement support for translating sections of type ELF_T_VDEF and ELF_T_VNEED.* Improve `elf_update()` to check that the executable header, the program header table, section contents and the section header table do not overlap, and to ensure that gaps between extents are filled with the fill character specified by `elf_fill()`.* Allow `Elf_Data` descriptors to have types and alignments differing from their containing section.* Remove functionality controlled by `LIBELF_TEST_HOOKS`.* Support processing of BSD-flavor archives.* Add knowledge of section types `SHT_GNU_ATTRIBUTES` and `SHT_GNU_LIBLIST`.* Use elftoolchain style symbol versioning.* Shared library version is bumped.[libdwarf]* The old libdwarf source code in lib/libdwarf has been removed. Instead, the new libdwarf is built from contrib/elftoolchain/libdwarf.* Support full DWARF3 and partial DWARF4 parsing.* Support DWARF2 generation.* Support for DWARF line number, call frame, location expression, macro info and address ranges, among other things.* The APIs for the new libdwarf are mostly compatible with the widely used LGPL libdwarf. Some of the incompatible APIs from the old libdwarf are kept as its own extensions. All the APIs are documented.* Use elftoolchain style symbol versioning.* Shared library version is bumped.[ctfconvert]* Switch to the APIs from the new libdwarf.* Improve die_mem_offset() so that DW_AT_data_member_location attributes generated by Clang 3.4 can be handled properly.* Make use of DW_AT_byte_size attribute of the member DIE to calculate the bits occupied by the member's type, without actually resolving the type. This way ctfconvert can deal with the case that Clang 3.4 sometimes emits DIE for struct/union member before emitting the DIE for the type of that member.Obtained from: elftoolchainNo objection: -toolchain mailing list List of files: /src/contrib/elftoolchain/libelf/Makefile Tue, 28 Jan 2014 21:38:54 +0000 Kai Wang <kaiw@FreeBSD.org> http://opengrok.net:8080/history/src/contrib/elftoolchain/libelf/Makefile#2de3b87a120614a3b053be7dd845b72f1e9ce804 Copy libelf, libdwarf and common files from vendor/ to contrib/.
