1143 .gnu.version does not yet contain correct info for defined and versioned
1144 symbols (means .gnu.version_d is not yet implemented).
1146 Implement gelf_update_* functions to create versioning data.

1180 Extension of linker script syntax.
1184 Implement section group handling in readelf.
1188 Implement section groups. This involved a lot of code moving. The
1189 new code is entirely untested since gas/gcc are currently not able to
1190 create section groups. ld works fine on files without section groups.
1194 Fix problem with adding more section in elf_newscn. The section pointers
1195 for the data buffers wasn't adjusted.
1197 Fix elf_getdata with nonzero second parameter. Correctly handle creation
1198 of internal data buffer for machines without unaligned access.

1255 readelf and nm use more libebl functions.
1257 Handle XINDEX correctly in nm and string.
1259 Add first machine ld backend library (i386).
1260 Use it. Recognize -r and --shared. Avoid using -lxxx parameters for -r.
1261 Create ELF header in output file. Change mode of output file according to
1262 output file type. Reorganize callback initialization in ld.
1266 Fix some memory leaks in libelf.
1270 Implement reading version script. Both inside linker scripts and via the
1271 --version-script command line parameter. Uses the same code.
1272 What remains to be done is to implement a data structure which allows
1273 efficient matching against the version names to decide which pattern
1276 Beginning of output generation and output writing functions.
1280 Finish implementation for DSO input file handling. Implement rpath, runpath,
1281 and LD_LIBRARY_PATH handling.
1285 make handling of e_shnum overflow in libelf standard conforming
1287 ld now actually can handle DSOs in linker scripts. Handling of DT_RUNPATH,
1288 DT_RPATH, -rpath, -rpath-link still remains to be implemented.
1290 fix handling of -L parameters. Make actual use of the default_paths element.
1292 make re-definition of symbols in and from DSO compatible with existing linker
1296 more work on assigning input sections to output sections.
1298 Add gelf_xlatetof and gelf_xlatetom which were accidently left out.
1300 Fix memory handling of section headers.
1304 Add many-section support to ld. Add various new command line parameters.
1305 Allow pagesize to be specified in linker script or on the command line.
1306 Collect input sections in list for the output section according to the rules
1307 specified in the linker script.
1311 Fix some problems in the internal list handling which had the result
1312 that we didn't look for some of the unresolved symbols.
1314 Free some memory if we know we don't need it anymore.
1316 Optimize the list of unresolved symbols. Throw out symbols which are
1321 Got file reading correct now. The files are all read while parsing
1322 the parameters. No creating of data structures to describe the linker
1323 command line. The symbol table is built up while reading the files.
1324 DSOs are handled now. -( -) handling is optimized.
1328 Linker read linker scripts everywhere. Handles --whole-archive. Recognizes
1329 --dynamic and --static. Collects defined and undefined symbols. Recognizes
1332 libebl now defines functions to call the callbacks. Add generic name handling
1333 in these new functions. Remove the code from readelf and call the new
1338 Start of linker. Basic argument parsing, finding of input files,
1339 linker script reading.
