1088 Correctly print versioning information for symbol tables.
1092 Implement preprocessing of linker script. Recognize -z combreloc.
1096 Implement -z ignore|record for ld.
1098 Implement creating of .gnu.version_r and .gnu.version sections. The
1099 .gnu.version does not yet contain correct info for defined and versioned
1100 symbols (means .gnu.version_d is not yet implemented).
1102 Implement gelf_update_* functions to create versioning data.
1106 Add DT_RUNPATH/DT_RPATH entries to dynamic section. Create .plt and
1107 .rel.plt sections (completely). Add support for all four PLT related
1108 dynamic section entries. Add callback function for PLT creation.

1111 now flags level 2 (deprecated features) usage.
1115 Create dynamic symbol table, dynamic string table, and hash table to ld.
1117 Add hash table histogram support to readelf.
1121 more work on elflint
1123 ld now creates the dynamic section and references it. Start adding entries
1128 Start implementing elflint.
1132 Fix handling of NOBITS sections in elf_getdata.
1134 Start implementing generation of executables and DSOs in ld.
1135 Generation of program header mostly done. Address computation done.
1136 Extension of linker script syntax.
1140 Implement section group handling in readelf.
1144 Implement section groups. This involved a lot of code moving. The
1145 new code is entirely untested since gas/gcc are currently not able to
1146 create section groups. ld works fine on files without section groups.
1150 Fix problem with adding more section in elf_newscn. The section pointers
1151 for the data buffers wasn't adjusted.
1153 Fix elf_getdata with nonzero second parameter. Correctly handle creation
1154 of internal data buffer for machines without unaligned access.
1158 Start adding support to selectively add sections. Includes support for
1160 Add --gc-sections/--no-gc-sections options.
1161 Add general section merging support.
1163 Fix a bug in section group support in strip.
1165 Fix some potential problems with hash value in dynamic hash implementation.
1169 section merging works in ld.
1173 Actually create data structures from version map file and use it to hide
1176 Implement -s -s for ld.
1180 Improve relocation table output in readelf. Avoid some crashes.
1181 Finish many section handling in readelf.
1183 Finish: finish implementation of ld -r. At least some simple tests pass.
1187 Fix a number of errors in ELF_C_WRITE handling.
1189 Almost finished implementation of ld -r. The data sections are all copied.
1190 Handling of symbol tables is missing.
1194 Handle DSO and archive input files correctly if -r option is given.
1196 Gracefully deal with no phdr in new file in libelf.
1197 Fix various small error handling problems.
1198 Don't mmap file for output unless the command says so.

1204 Fix some problems with recursive handling of archives in libelf.
1206 Improve messages printed by nm.
1208 Add symbol binding name handling to libebl. Fix section name handling in
1211 readelf and nm use more libebl functions.
1213 Handle XINDEX correctly in nm and string.
1215 Add first machine ld backend library (i386).
1216 Use it. Recognize -r and --shared. Avoid using -lxxx parameters for -r.
1217 Create ELF header in output file. Change mode of output file according to
1218 output file type. Reorganize callback initialization in ld.
1222 Fix some memory leaks in libelf.
1226 Implement reading version script. Both inside linker scripts and via the
1227 --version-script command line parameter. Uses the same code.
1228 What remains to be done is to implement a data structure which allows
1229 efficient matching against the version names to decide which pattern
1232 Beginning of output generation and output writing functions.
1236 Finish implementation for DSO input file handling. Implement rpath, runpath,
1237 and LD_LIBRARY_PATH handling.
1241 make handling of e_shnum overflow in libelf standard conforming
1243 ld now actually can handle DSOs in linker scripts. Handling of DT_RUNPATH,
1244 DT_RPATH, -rpath, -rpath-link still remains to be implemented.
1246 fix handling of -L parameters. Make actual use of the default_paths element.
1248 make re-definition of symbols in and from DSO compatible with existing linker
1252 more work on assigning input sections to output sections.
1254 Add gelf_xlatetof and gelf_xlatetom which were accidently left out.
1256 Fix memory handling of section headers.
1260 Add many-section support to ld. Add various new command line parameters.
1261 Allow pagesize to be specified in linker script or on the command line.
1262 Collect input sections in list for the output section according to the rules
1263 specified in the linker script.
1267 Fix some problems in the internal list handling which had the result
1268 that we didn't look for some of the unresolved symbols.
1270 Free some memory if we know we don't need it anymore.
1272 Optimize the list of unresolved symbols. Throw out symbols which are
1277 Got file reading correct now. The files are all read while parsing
1278 the parameters. No creating of data structures to describe the linker
1279 command line. The symbol table is built up while reading the files.
1280 DSOs are handled now. -( -) handling is optimized.
1284 Linker read linker scripts everywhere. Handles --whole-archive. Recognizes
1285 --dynamic and --static. Collects defined and undefined symbols. Recognizes
1288 libebl now defines functions to call the callbacks. Add generic name handling
1289 in these new functions. Remove the code from readelf and call the new
1294 Start of linker. Basic argument parsing, finding of input files,
1295 linker script reading.
1299 Implement dwarf_get_fde_n(), dwarf_get_abbrev(), dwarf_get_abbrev_tag(),
1300 dwarf_get_abbrev_code(), dwarf_get_abbrev_children_flag(),
