1202 Implement creating of .gnu.version_r and .gnu.version sections. The
1203 .gnu.version does not yet contain correct info for defined and versioned
1204 symbols (means .gnu.version_d is not yet implemented).
1206 Implement gelf_update_* functions to create versioning data.
1210 Add DT_RUNPATH/DT_RPATH entries to dynamic section. Create .plt and
1211 .rel.plt sections (completely). Add support for all four PLT related

1240 Extension of linker script syntax.
1244 Implement section group handling in readelf.
1248 Implement section groups. This involved a lot of code moving. The
1249 new code is entirely untested since gas/gcc are currently not able to
1250 create section groups. ld works fine on files without section groups.
1254 Fix problem with adding more section in elf_newscn. The section pointers
1255 for the data buffers wasn't adjusted.
1257 Fix elf_getdata with nonzero second parameter. Correctly handle creation
1258 of internal data buffer for machines without unaligned access.

1315 readelf and nm use more libebl functions.
1317 Handle XINDEX correctly in nm and string.
1319 Add first machine ld backend library (i386).
1320 Use it. Recognize -r and --shared. Avoid using -lxxx parameters for -r.
1321 Create ELF header in output file. Change mode of output file according to
1322 output file type. Reorganize callback initialization in ld.
1326 Fix some memory leaks in libelf.
1330 Implement reading version script. Both inside linker scripts and via the
1331 --version-script command line parameter. Uses the same code.
1332 What remains to be done is to implement a data structure which allows
1333 efficient matching against the version names to decide which pattern
1336 Beginning of output generation and output writing functions.
1340 Finish implementation for DSO input file handling. Implement rpath, runpath,
1341 and LD_LIBRARY_PATH handling.
1345 make handling of e_shnum overflow in libelf standard conforming
1347 ld now actually can handle DSOs in linker scripts. Handling of DT_RUNPATH,
1348 DT_RPATH, -rpath, -rpath-link still remains to be implemented.
1350 fix handling of -L parameters. Make actual use of the default_paths element.
1352 make re-definition of symbols in and from DSO compatible with existing linker
1356 more work on assigning input sections to output sections.
1358 Add gelf_xlatetof and gelf_xlatetom which were accidently left out.
1360 Fix memory handling of section headers.
1364 Add many-section support to ld. Add various new command line parameters.
1365 Allow pagesize to be specified in linker script or on the command line.
1366 Collect input sections in list for the output section according to the rules
1367 specified in the linker script.
1371 Fix some problems in the internal list handling which had the result
1372 that we didn't look for some of the unresolved symbols.
1374 Free some memory if we know we don't need it anymore.
1376 Optimize the list of unresolved symbols. Throw out symbols which are
1381 Got file reading correct now. The files are all read while parsing
1382 the parameters. No creating of data structures to describe the linker
1383 command line. The symbol table is built up while reading the files.
1384 DSOs are handled now. -( -) handling is optimized.
1388 Linker read linker scripts everywhere. Handles --whole-archive. Recognizes
1389 --dynamic and --static. Collects defined and undefined symbols. Recognizes
1392 libebl now defines functions to call the callbacks. Add generic name handling
1393 in these new functions. Remove the code from readelf and call the new
1398 Start of linker. Basic argument parsing, finding of input files,
1399 linker script reading.
