1181 .gnu.version does not yet contain correct info for defined and versioned
1182 symbols (means .gnu.version_d is not yet implemented).
1184 Implement gelf_update_* functions to create versioning data.

1218 Extension of linker script syntax.
1222 Implement section group handling in readelf.
1226 Implement section groups. This involved a lot of code moving. The
1227 new code is entirely untested since gas/gcc are currently not able to
1228 create section groups. ld works fine on files without section groups.
1232 Fix problem with adding more section in elf_newscn. The section pointers
1233 for the data buffers wasn't adjusted.
1235 Fix elf_getdata with nonzero second parameter. Correctly handle creation

1293 readelf and nm use more libebl functions.
1295 Handle XINDEX correctly in nm and string.
1297 Add first machine ld backend library (i386).
1298 Use it. Recognize -r and --shared. Avoid using -lxxx parameters for -r.
1299 Create ELF header in output file. Change mode of output file according to
1300 output file type. Reorganize callback initialization in ld.
1304 Fix some memory leaks in libelf.
1308 Implement reading version script. Both inside linker scripts and via the
1309 --version-script command line parameter. Uses the same code.
1310 What remains to be done is to implement a data structure which allows
1311 efficient matching against the version names to decide which pattern
1314 Beginning of output generation and output writing functions.
1318 Finish implementation for DSO input file handling. Implement rpath, runpath,
1319 and LD_LIBRARY_PATH handling.
1323 make handling of e_shnum overflow in libelf standard conforming
1325 ld now actually can handle DSOs in linker scripts. Handling of DT_RUNPATH,
1326 DT_RPATH, -rpath, -rpath-link still remains to be implemented.
1328 fix handling of -L parameters. Make actual use of the default_paths element.
1330 make re-definition of symbols in and from DSO compatible with existing linker
1334 more work on assigning input sections to output sections.
1336 Add gelf_xlatetof and gelf_xlatetom which were accidently left out.
1338 Fix memory handling of section headers.
1342 Add many-section support to ld. Add various new command line parameters.
1343 Allow pagesize to be specified in linker script or on the command line.
1344 Collect input sections in list for the output section according to the rules
1345 specified in the linker script.
1349 Fix some problems in the internal list handling which had the result
1350 that we didn't look for some of the unresolved symbols.
1352 Free some memory if we know we don't need it anymore.
1354 Optimize the list of unresolved symbols. Throw out symbols which are
1359 Got file reading correct now. The files are all read while parsing
1360 the parameters. No creating of data structures to describe the linker
1361 command line. The symbol table is built up while reading the files.
1362 DSOs are handled now. -( -) handling is optimized.
1366 Linker read linker scripts everywhere. Handles --whole-archive. Recognizes
1367 --dynamic and --static. Collects defined and undefined symbols. Recognizes
1370 libebl now defines functions to call the callbacks. Add generic name handling
1371 in these new functions. Remove the code from readelf and call the new
1376 Start of linker. Basic argument parsing, finding of input files,
1377 linker script reading.
