1004 libelf: add elf_getshnum and elf_getshstrndx
1006 libebl: update section type name function
1008 elflint: tons of fixes wrt large number of sections. New tests in this area.
1009 Same amount of other bug fixes.

1040 ld: generate correct version info in dynsym without --export-dynamic and
1045 Fix check of various e_*size entries in elflint.
1047 Handle text output in asm_newsym.
1049 Finish checks in asm-tst3.

1055 Introduce *.sym files to restrict export from DSOs.
1057 Use attribute_hidden and internal_function to optimize DSO code.
1059 Add TLS definitions in elf.h and handle them in readelf.
1061 Fix bug in verdef section generation in ld.
1063 Add initial libasm code.

1072 Improve readelf output format. Respect various sh_link/sh_info values.
1073 Correctly print versioning information for symbol tables.
1077 Implement preprocessing of linker script. Recognize -z combreloc.
1081 Implement -z ignore|record for ld.
1083 Implement creating of .gnu.version_r and .gnu.version sections. The
1084 .gnu.version does not yet contain correct info for defined and versioned
1085 symbols (means .gnu.version_d is not yet implemented).
1087 Implement gelf_update_* functions to create versioning data.
1091 Add DT_RUNPATH/DT_RPATH entries to dynamic section. Create .plt and
1092 .rel.plt sections (completely). Add support for all four PLT related
1093 dynamic section entries. Add callback function for PLT creation.
1095 More tests in elflint. Add support for very strict checking which for
1096 now flags level 2 (deprecated features) usage.
1100 Create dynamic symbol table, dynamic string table, and hash table to ld.
1102 Add hash table histogram support to readelf.
1106 more work on elflint
1108 ld now creates the dynamic section and references it. Start adding entries
1113 Start implementing elflint.
1117 Fix handling of NOBITS sections in elf_getdata.
1119 Start implementing generation of executables and DSOs in ld.
1120 Generation of program header mostly done. Address computation done.
1121 Extension of linker script syntax.
1125 Implement section group handling in readelf.
1129 Implement section groups. This involved a lot of code moving. The
1130 new code is entirely untested since gas/gcc are currently not able to
1131 create section groups. ld works fine on files without section groups.
1135 Fix problem with adding more section in elf_newscn. The section pointers
1136 for the data buffers wasn't adjusted.
1138 Fix elf_getdata with nonzero second parameter. Correctly handle creation
1139 of internal data buffer for machines without unaligned access.
1143 Start adding support to selectively add sections. Includes support for
1145 Add --gc-sections/--no-gc-sections options.
1146 Add general section merging support.
1148 Fix a bug in section group support in strip.
1150 Fix some potential problems with hash value in dynamic hash implementation.
1154 section merging works in ld.
1158 Actually create data structures from version map file and use it to hide
1161 Implement -s -s for ld.
1165 Improve relocation table output in readelf. Avoid some crashes.
1166 Finish many section handling in readelf.
1168 Finish: finish implementation of ld -r. At least some simple tests pass.
1172 Fix a number of errors in ELF_C_WRITE handling.
1174 Almost finished implementation of ld -r. The data sections are all copied.
1175 Handling of symbol tables is missing.
1179 Handle DSO and archive input files correctly if -r option is given.
1181 Gracefully deal with no phdr in new file in libelf.
1182 Fix various small error handling problems.
1183 Don't mmap file for output unless the command says so.

1189 Fix some problems with recursive handling of archives in libelf.
1191 Improve messages printed by nm.
1193 Add symbol binding name handling to libebl. Fix section name handling in
1196 readelf and nm use more libebl functions.
1198 Handle XINDEX correctly in nm and string.
1200 Add first machine ld backend library (i386).
1201 Use it. Recognize -r and --shared. Avoid using -lxxx parameters for -r.
1202 Create ELF header in output file. Change mode of output file according to
1203 output file type. Reorganize callback initialization in ld.
1207 Fix some memory leaks in libelf.
1211 Implement reading version script. Both inside linker scripts and via the
1212 --version-script command line parameter. Uses the same code.
1213 What remains to be done is to implement a data structure which allows
1214 efficient matching against the version names to decide which pattern
1217 Beginning of output generation and output writing functions.
1221 Finish implementation for DSO input file handling. Implement rpath, runpath,
1222 and LD_LIBRARY_PATH handling.
1226 make handling of e_shnum overflow in libelf standard conforming
1228 ld now actually can handle DSOs in linker scripts. Handling of DT_RUNPATH,
1229 DT_RPATH, -rpath, -rpath-link still remains to be implemented.
1231 fix handling of -L parameters. Make actual use of the default_paths element.
1233 make re-definition of symbols in and from DSO compatible with existing linker
1237 more work on assigning input sections to output sections.
1239 Add gelf_xlatetof and gelf_xlatetom which were accidently left out.
1241 Fix memory handling of section headers.
1245 Add many-section support to ld. Add various new command line parameters.
1246 Allow pagesize to be specified in linker script or on the command line.
1247 Collect input sections in list for the output section according to the rules
1248 specified in the linker script.
1252 Fix some problems in the internal list handling which had the result
1253 that we didn't look for some of the unresolved symbols.
1255 Free some memory if we know we don't need it anymore.
1257 Optimize the list of unresolved symbols. Throw out symbols which are
1262 Got file reading correct now. The files are all read while parsing
1263 the parameters. No creating of data structures to describe the linker
1264 command line. The symbol table is built up while reading the files.
1265 DSOs are handled now. -( -) handling is optimized.
1269 Linker read linker scripts everywhere. Handles --whole-archive. Recognizes
1270 --dynamic and --static. Collects defined and undefined symbols. Recognizes
1273 libebl now defines functions to call the callbacks. Add generic name handling
1274 in these new functions. Remove the code from readelf and call the new
1279 Start of linker. Basic argument parsing, finding of input files,
1280 linker script reading.
1284 Implement dwarf_get_fde_n(), dwarf_get_abbrev(), dwarf_get_abbrev_tag(),
1285 dwarf_get_abbrev_code(), dwarf_get_abbrev_children_flag(),
