1206 Implement creating of .gnu.version_r and .gnu.version sections. The
1207 .gnu.version does not yet contain correct info for defined and versioned
1208 symbols (means .gnu.version_d is not yet implemented).
1210 Implement gelf_update_* functions to create versioning data.

1252 Implement section groups. This involved a lot of code moving. The
1253 new code is entirely untested since gas/gcc are currently not able to
1254 create section groups. ld works fine on files without section groups.
1258 Fix problem with adding more section in elf_newscn. The section pointers
1259 for the data buffers wasn't adjusted.
1261 Fix elf_getdata with nonzero second parameter. Correctly handle creation

1319 readelf and nm use more libebl functions.
1321 Handle XINDEX correctly in nm and string.
1323 Add first machine ld backend library (i386).
1324 Use it. Recognize -r and --shared. Avoid using -lxxx parameters for -r.
1325 Create ELF header in output file. Change mode of output file according to
1326 output file type. Reorganize callback initialization in ld.
1330 Fix some memory leaks in libelf.
1334 Implement reading version script. Both inside linker scripts and via the
1335 --version-script command line parameter. Uses the same code.
1336 What remains to be done is to implement a data structure which allows
1337 efficient matching against the version names to decide which pattern
1340 Beginning of output generation and output writing functions.
1344 Finish implementation for DSO input file handling. Implement rpath, runpath,
1345 and LD_LIBRARY_PATH handling.
1349 make handling of e_shnum overflow in libelf standard conforming
1351 ld now actually can handle DSOs in linker scripts. Handling of DT_RUNPATH,
1352 DT_RPATH, -rpath, -rpath-link still remains to be implemented.
1354 fix handling of -L parameters. Make actual use of the default_paths element.
1356 make re-definition of symbols in and from DSO compatible with existing linker
1360 more work on assigning input sections to output sections.
1362 Add gelf_xlatetof and gelf_xlatetom which were accidently left out.
1364 Fix memory handling of section headers.
1368 Add many-section support to ld. Add various new command line parameters.
1369 Allow pagesize to be specified in linker script or on the command line.
1370 Collect input sections in list for the output section according to the rules
1371 specified in the linker script.
1375 Fix some problems in the internal list handling which had the result
1376 that we didn't look for some of the unresolved symbols.
1378 Free some memory if we know we don't need it anymore.
1380 Optimize the list of unresolved symbols. Throw out symbols which are
1385 Got file reading correct now. The files are all read while parsing
1386 the parameters. No creating of data structures to describe the linker
1387 command line. The symbol table is built up while reading the files.
1388 DSOs are handled now. -( -) handling is optimized.
1392 Linker read linker scripts everywhere. Handles --whole-archive. Recognizes
1393 --dynamic and --static. Collects defined and undefined symbols. Recognizes
1396 libebl now defines functions to call the callbacks. Add generic name handling
1397 in these new functions. Remove the code from readelf and call the new
1402 Start of linker. Basic argument parsing, finding of input files,
1403 linker script reading.
