1164 Implement creating of .gnu.version_r and .gnu.version sections. The
1165 .gnu.version does not yet contain correct info for defined and versioned
1166 symbols (means .gnu.version_d is not yet implemented).
1168 Implement gelf_update_* functions to create versioning data.

1202 Extension of linker script syntax.
1206 Implement section group handling in readelf.
1210 Implement section groups. This involved a lot of code moving. The
1211 new code is entirely untested since gas/gcc are currently not able to
1212 create section groups. ld works fine on files without section groups.
1216 Fix problem with adding more section in elf_newscn. The section pointers
1217 for the data buffers wasn't adjusted.
1219 Fix elf_getdata with nonzero second parameter. Correctly handle creation

1277 readelf and nm use more libebl functions.
1279 Handle XINDEX correctly in nm and string.
1281 Add first machine ld backend library (i386).
1282 Use it. Recognize -r and --shared. Avoid using -lxxx parameters for -r.
1283 Create ELF header in output file. Change mode of output file according to
1284 output file type. Reorganize callback initialization in ld.
1288 Fix some memory leaks in libelf.
1292 Implement reading version script. Both inside linker scripts and via the
1293 --version-script command line parameter. Uses the same code.
1294 What remains to be done is to implement a data structure which allows
1295 efficient matching against the version names to decide which pattern
1298 Beginning of output generation and output writing functions.
1302 Finish implementation for DSO input file handling. Implement rpath, runpath,
1303 and LD_LIBRARY_PATH handling.
1307 make handling of e_shnum overflow in libelf standard conforming
1309 ld now actually can handle DSOs in linker scripts. Handling of DT_RUNPATH,
1310 DT_RPATH, -rpath, -rpath-link still remains to be implemented.
1312 fix handling of -L parameters. Make actual use of the default_paths element.
1314 make re-definition of symbols in and from DSO compatible with existing linker
1318 more work on assigning input sections to output sections.
1320 Add gelf_xlatetof and gelf_xlatetom which were accidently left out.
1322 Fix memory handling of section headers.
1326 Add many-section support to ld. Add various new command line parameters.
1327 Allow pagesize to be specified in linker script or on the command line.
1328 Collect input sections in list for the output section according to the rules
1329 specified in the linker script.
1333 Fix some problems in the internal list handling which had the result
1334 that we didn't look for some of the unresolved symbols.
1336 Free some memory if we know we don't need it anymore.
1338 Optimize the list of unresolved symbols. Throw out symbols which are
1343 Got file reading correct now. The files are all read while parsing
1344 the parameters. No creating of data structures to describe the linker
1345 command line. The symbol table is built up while reading the files.
1346 DSOs are handled now. -( -) handling is optimized.
1350 Linker read linker scripts everywhere. Handles --whole-archive. Recognizes
1351 --dynamic and --static. Collects defined and undefined symbols. Recognizes
1354 libebl now defines functions to call the callbacks. Add generic name handling
1355 in these new functions. Remove the code from readelf and call the new
1360 Start of linker. Basic argument parsing, finding of input files,
1361 linker script reading.
