992 elflint: more tests on section groups. Improve performance on existing
997 ld: add undefined symbols to dynamic symbol table if --export-dynamic is
1000 ld: fix value of e_entry
1004 elflint: print section names in error messages
1006 elflint: mustn't warn about multiple DT_NULL
1008 ld: don't emit all symbols if --export-dynamic is not given
1010 ld: correct compute symbol address in output file (section index was off by 1)
1012 ld: generate correct version info in dynsym without --export-dynamic and
1017 Fix check of various e_*size entries in elflint.
1019 Handle text output in asm_newsym.
1021 Finish checks in asm-tst3.
1025 Update to autoconf 2.53, automake 1.6, gettext 0.11+.
1027 Introduce *.sym files to restrict export from DSOs.
1029 Use attribute_hidden and internal_function to optimize DSO code.
1031 Add TLS definitions in elf.h and handle them in readelf.
1033 Fix bug in verdef section generation in ld.
1035 Add initial libasm code.
1039 Implement better hash size optimization heuristic in ld. It uses a formula
1040 taking number of tests into account.
1042 Lots of small bug fixes.
1044 Improve readelf output format. Respect various sh_link/sh_info values.
1045 Correctly print versioning information for symbol tables.
1049 Implement preprocessing of linker script. Recognize -z combreloc.
1053 Implement -z ignore|record for ld.
1055 Implement creating of .gnu.version_r and .gnu.version sections. The
1056 .gnu.version does not yet contain correct info for defined and versioned
1057 symbols (means .gnu.version_d is not yet implemented).
1059 Implement gelf_update_* functions to create versioning data.
1063 Add DT_RUNPATH/DT_RPATH entries to dynamic section. Create .plt and
1064 .rel.plt sections (completely). Add support for all four PLT related
1065 dynamic section entries. Add callback function for PLT creation.
1067 More tests in elflint. Add support for very strict checking which for
1068 now flags level 2 (deprecated features) usage.
1072 Create dynamic symbol table, dynamic string table, and hash table to ld.
1074 Add hash table histogram support to readelf.
1078 more work on elflint
1080 ld now creates the dynamic section and references it. Start adding entries
1085 Start implementing elflint.
1089 Fix handling of NOBITS sections in elf_getdata.
1091 Start implementing generation of executables and DSOs in ld.
1092 Generation of program header mostly done. Address computation done.
1093 Extension of linker script syntax.
1097 Implement section group handling in readelf.
1101 Implement section groups. This involved a lot of code moving. The
1102 new code is entirely untested since gas/gcc are currently not able to
1103 create section groups. ld works fine on files without section groups.
1107 Fix problem with adding more section in elf_newscn. The section pointers
1108 for the data buffers wasn't adjusted.
1110 Fix elf_getdata with nonzero second parameter. Correctly handle creation
1111 of internal data buffer for machines without unaligned access.
1115 Start adding support to selectively add sections. Includes support for
1117 Add --gc-sections/--no-gc-sections options.
1118 Add general section merging support.
1120 Fix a bug in section group support in strip.
1122 Fix some potential problems with hash value in dynamic hash implementation.
1126 section merging works in ld.
1130 Actually create data structures from version map file and use it to hide
1133 Implement -s -s for ld.
1137 Improve relocation table output in readelf. Avoid some crashes.
1138 Finish many section handling in readelf.
1140 Finish: finish implementation of ld -r. At least some simple tests pass.
1144 Fix a number of errors in ELF_C_WRITE handling.
1146 Almost finished implementation of ld -r. The data sections are all copied.
1147 Handling of symbol tables is missing.
1151 Handle DSO and archive input files correctly if -r option is given.
1153 Gracefully deal with no phdr in new file in libelf.
1154 Fix various small error handling problems.
1155 Don't mmap file for output unless the command says so.
1157 Add code to create ELF section header table to ld finalize routines.
1161 Fix some problems with recursive handling of archives in libelf.
1163 Improve messages printed by nm.
1165 Add symbol binding name handling to libebl. Fix section name handling in
1168 readelf and nm use more libebl functions.
1170 Handle XINDEX correctly in nm and string.
1172 Add first machine ld backend library (i386).
1173 Use it. Recognize -r and --shared. Avoid using -lxxx parameters for -r.
1174 Create ELF header in output file. Change mode of output file according to
1175 output file type. Reorganize callback initialization in ld.
1179 Fix some memory leaks in libelf.
1183 Implement reading version script. Both inside linker scripts and via the
1184 --version-script command line parameter. Uses the same code.
1185 What remains to be done is to implement a data structure which allows
1186 efficient matching against the version names to decide which pattern
1189 Beginning of output generation and output writing functions.
1193 Finish implementation for DSO input file handling. Implement rpath, runpath,
1194 and LD_LIBRARY_PATH handling.
1198 make handling of e_shnum overflow in libelf standard conforming
1200 ld now actually can handle DSOs in linker scripts. Handling of DT_RUNPATH,
1201 DT_RPATH, -rpath, -rpath-link still remains to be implemented.
1203 fix handling of -L parameters. Make actual use of the default_paths element.
1205 make re-definition of symbols in and from DSO compatible with existing linker
1209 more work on assigning input sections to output sections.
1211 Add gelf_xlatetof and gelf_xlatetom which were accidently left out.
1213 Fix memory handling of section headers.
1217 Add many-section support to ld. Add various new command line parameters.
1218 Allow pagesize to be specified in linker script or on the command line.
1219 Collect input sections in list for the output section according to the rules
1220 specified in the linker script.
1224 Fix some problems in the internal list handling which had the result
1225 that we didn't look for some of the unresolved symbols.
1227 Free some memory if we know we don't need it anymore.
1229 Optimize the list of unresolved symbols. Throw out symbols which are
1234 Got file reading correct now. The files are all read while parsing
1235 the parameters. No creating of data structures to describe the linker
1236 command line. The symbol table is built up while reading the files.
1237 DSOs are handled now. -( -) handling is optimized.
1241 Linker read linker scripts everywhere. Handles --whole-archive. Recognizes
1242 --dynamic and --static. Collects defined and undefined symbols. Recognizes
1245 libebl now defines functions to call the callbacks. Add generic name handling
1246 in these new functions. Remove the code from readelf and call the new
1251 Start of linker. Basic argument parsing, finding of input files,
1252 linker script reading.
1256 Implement dwarf_get_fde_n(), dwarf_get_abbrev(), dwarf_get_abbrev_tag(),
1257 dwarf_get_abbrev_code(), dwarf_get_abbrev_children_flag(),
