1203 Implement creating of .gnu.version_r and .gnu.version sections. The
1204 .gnu.version does not yet contain correct info for defined and versioned
1205 symbols (means .gnu.version_d is not yet implemented).
1207 Implement gelf_update_* functions to create versioning data.
1211 Add DT_RUNPATH/DT_RPATH entries to dynamic section. Create .plt and
1212 .rel.plt sections (completely). Add support for all four PLT related

1241 Extension of linker script syntax.
1245 Implement section group handling in readelf.
1249 Implement section groups. This involved a lot of code moving. The
1250 new code is entirely untested since gas/gcc are currently not able to
1251 create section groups. ld works fine on files without section groups.
1255 Fix problem with adding more section in elf_newscn. The section pointers
1256 for the data buffers wasn't adjusted.
1258 Fix elf_getdata with nonzero second parameter. Correctly handle creation
1259 of internal data buffer for machines without unaligned access.

1316 readelf and nm use more libebl functions.
1318 Handle XINDEX correctly in nm and string.
1320 Add first machine ld backend library (i386).
1321 Use it. Recognize -r and --shared. Avoid using -lxxx parameters for -r.
1322 Create ELF header in output file. Change mode of output file according to
1323 output file type. Reorganize callback initialization in ld.
1327 Fix some memory leaks in libelf.
1331 Implement reading version script. Both inside linker scripts and via the
1332 --version-script command line parameter. Uses the same code.
1333 What remains to be done is to implement a data structure which allows
1334 efficient matching against the version names to decide which pattern
1337 Beginning of output generation and output writing functions.
1341 Finish implementation for DSO input file handling. Implement rpath, runpath,
1342 and LD_LIBRARY_PATH handling.
1346 make handling of e_shnum overflow in libelf standard conforming
1348 ld now actually can handle DSOs in linker scripts. Handling of DT_RUNPATH,
1349 DT_RPATH, -rpath, -rpath-link still remains to be implemented.
1351 fix handling of -L parameters. Make actual use of the default_paths element.
1353 make re-definition of symbols in and from DSO compatible with existing linker
1357 more work on assigning input sections to output sections.
1359 Add gelf_xlatetof and gelf_xlatetom which were accidently left out.
1361 Fix memory handling of section headers.
1365 Add many-section support to ld. Add various new command line parameters.
1366 Allow pagesize to be specified in linker script or on the command line.
1367 Collect input sections in list for the output section according to the rules
1368 specified in the linker script.
1372 Fix some problems in the internal list handling which had the result
1373 that we didn't look for some of the unresolved symbols.
1375 Free some memory if we know we don't need it anymore.
1377 Optimize the list of unresolved symbols. Throw out symbols which are
1382 Got file reading correct now. The files are all read while parsing
1383 the parameters. No creating of data structures to describe the linker
1384 command line. The symbol table is built up while reading the files.
1385 DSOs are handled now. -( -) handling is optimized.
1389 Linker read linker scripts everywhere. Handles --whole-archive. Recognizes
1390 --dynamic and --static. Collects defined and undefined symbols. Recognizes
1393 libebl now defines functions to call the callbacks. Add generic name handling
1394 in these new functions. Remove the code from readelf and call the new
1399 Start of linker. Basic argument parsing, finding of input files,
1400 linker script reading.
