1097 Correctly print versioning information for symbol tables.
1101 Implement preprocessing of linker script. Recognize -z combreloc.
1105 Implement -z ignore|record for ld.
1107 Implement creating of .gnu.version_r and .gnu.version sections. The
1108 .gnu.version does not yet contain correct info for defined and versioned
1109 symbols (means .gnu.version_d is not yet implemented).
1111 Implement gelf_update_* functions to create versioning data.
1115 Add DT_RUNPATH/DT_RPATH entries to dynamic section. Create .plt and
1116 .rel.plt sections (completely). Add support for all four PLT related

1126 Add hash table histogram support to readelf.
1130 more work on elflint
1132 ld now creates the dynamic section and references it. Start adding entries

1144 Generation of program header mostly done. Address computation done.
1145 Extension of linker script syntax.
1149 Implement section group handling in readelf.
1153 Implement section groups. This involved a lot of code moving. The
1154 new code is entirely untested since gas/gcc are currently not able to
1155 create section groups. ld works fine on files without section groups.
1159 Fix problem with adding more section in elf_newscn. The section pointers
1160 for the data buffers wasn't adjusted.
1162 Fix elf_getdata with nonzero second parameter. Correctly handle creation
1163 of internal data buffer for machines without unaligned access.
1167 Start adding support to selectively add sections. Includes support for
1169 Add --gc-sections/--no-gc-sections options.
1170 Add general section merging support.

1185 Implement -s -s for ld.
1189 Improve relocation table output in readelf. Avoid some crashes.
1190 Finish many section handling in readelf.
1192 Finish: finish implementation of ld -r. At least some simple tests pass.
1196 Fix a number of errors in ELF_C_WRITE handling.
1198 Almost finished implementation of ld -r. The data sections are all copied.
1199 Handling of symbol tables is missing.

1213 Fix some problems with recursive handling of archives in libelf.
1215 Improve messages printed by nm.
1217 Add symbol binding name handling to libebl. Fix section name handling in
1220 readelf and nm use more libebl functions.
1222 Handle XINDEX correctly in nm and string.
1224 Add first machine ld backend library (i386).
1225 Use it. Recognize -r and --shared. Avoid using -lxxx parameters for -r.
1226 Create ELF header in output file. Change mode of output file according to
1227 output file type. Reorganize callback initialization in ld.
1231 Fix some memory leaks in libelf.
1235 Implement reading version script. Both inside linker scripts and via the
1236 --version-script command line parameter. Uses the same code.
1237 What remains to be done is to implement a data structure which allows
1238 efficient matching against the version names to decide which pattern
1241 Beginning of output generation and output writing functions.
1245 Finish implementation for DSO input file handling. Implement rpath, runpath,
1246 and LD_LIBRARY_PATH handling.
1250 make handling of e_shnum overflow in libelf standard conforming
1252 ld now actually can handle DSOs in linker scripts. Handling of DT_RUNPATH,
1253 DT_RPATH, -rpath, -rpath-link still remains to be implemented.
1255 fix handling of -L parameters. Make actual use of the default_paths element.
1257 make re-definition of symbols in and from DSO compatible with existing linker
1261 more work on assigning input sections to output sections.
1263 Add gelf_xlatetof and gelf_xlatetom which were accidently left out.
1265 Fix memory handling of section headers.
1269 Add many-section support to ld. Add various new command line parameters.
1270 Allow pagesize to be specified in linker script or on the command line.
1271 Collect input sections in list for the output section according to the rules
1272 specified in the linker script.
1276 Fix some problems in the internal list handling which had the result
1277 that we didn't look for some of the unresolved symbols.
1279 Free some memory if we know we don't need it anymore.
1281 Optimize the list of unresolved symbols. Throw out symbols which are
1286 Got file reading correct now. The files are all read while parsing
1287 the parameters. No creating of data structures to describe the linker
1288 command line. The symbol table is built up while reading the files.
1289 DSOs are handled now. -( -) handling is optimized.
1293 Linker read linker scripts everywhere. Handles --whole-archive. Recognizes
1294 --dynamic and --static. Collects defined and undefined symbols. Recognizes
1297 libebl now defines functions to call the callbacks. Add generic name handling
1298 in these new functions. Remove the code from readelf and call the new
1303 Start of linker. Basic argument parsing, finding of input files,
1304 linker script reading.
1308 Implement dwarf_get_fde_n(), dwarf_get_abbrev(), dwarf_get_abbrev_tag(),
1309 dwarf_get_abbrev_code(), dwarf_get_abbrev_children_flag(),
