1199 Implement creating of .gnu.version_r and .gnu.version sections. The
1200 .gnu.version does not yet contain correct info for defined and versioned
1201 symbols (means .gnu.version_d is not yet implemented).
1203 Implement gelf_update_* functions to create versioning data.
1207 Add DT_RUNPATH/DT_RPATH entries to dynamic section. Create .plt and
1208 .rel.plt sections (completely). Add support for all four PLT related

1212 now flags level 2 (deprecated features) usage.
1216 Create dynamic symbol table, dynamic string table, and hash table to ld.
1218 Add hash table histogram support to readelf.
1222 more work on elflint
1224 ld now creates the dynamic section and references it. Start adding entries

1236 Generation of program header mostly done. Address computation done.
1237 Extension of linker script syntax.
1241 Implement section group handling in readelf.
1245 Implement section groups. This involved a lot of code moving. The
1246 new code is entirely untested since gas/gcc are currently not able to
1247 create section groups. ld works fine on files without section groups.
1251 Fix problem with adding more section in elf_newscn. The section pointers
1252 for the data buffers wasn't adjusted.
1254 Fix elf_getdata with nonzero second parameter. Correctly handle creation
1255 of internal data buffer for machines without unaligned access.
1259 Start adding support to selectively add sections. Includes support for
1261 Add --gc-sections/--no-gc-sections options.
1262 Add general section merging support.

1281 Improve relocation table output in readelf. Avoid some crashes.
1282 Finish many section handling in readelf.
1284 Finish: finish implementation of ld -r. At least some simple tests pass.
1288 Fix a number of errors in ELF_C_WRITE handling.
1290 Almost finished implementation of ld -r. The data sections are all copied.
1291 Handling of symbol tables is missing.

1305 Fix some problems with recursive handling of archives in libelf.
1307 Improve messages printed by nm.
1309 Add symbol binding name handling to libebl. Fix section name handling in
1312 readelf and nm use more libebl functions.
1314 Handle XINDEX correctly in nm and string.
1316 Add first machine ld backend library (i386).
1317 Use it. Recognize -r and --shared. Avoid using -lxxx parameters for -r.
1318 Create ELF header in output file. Change mode of output file according to
1319 output file type. Reorganize callback initialization in ld.
1323 Fix some memory leaks in libelf.
1327 Implement reading version script. Both inside linker scripts and via the
1328 --version-script command line parameter. Uses the same code.
1329 What remains to be done is to implement a data structure which allows
1330 efficient matching against the version names to decide which pattern
1333 Beginning of output generation and output writing functions.
1337 Finish implementation for DSO input file handling. Implement rpath, runpath,
1338 and LD_LIBRARY_PATH handling.
1342 make handling of e_shnum overflow in libelf standard conforming
1344 ld now actually can handle DSOs in linker scripts. Handling of DT_RUNPATH,
1345 DT_RPATH, -rpath, -rpath-link still remains to be implemented.
1347 fix handling of -L parameters. Make actual use of the default_paths element.
1349 make re-definition of symbols in and from DSO compatible with existing linker
1353 more work on assigning input sections to output sections.
1355 Add gelf_xlatetof and gelf_xlatetom which were accidently left out.
1357 Fix memory handling of section headers.
1361 Add many-section support to ld. Add various new command line parameters.
1362 Allow pagesize to be specified in linker script or on the command line.
1363 Collect input sections in list for the output section according to the rules
1364 specified in the linker script.
1368 Fix some problems in the internal list handling which had the result
1369 that we didn't look for some of the unresolved symbols.
1371 Free some memory if we know we don't need it anymore.
1373 Optimize the list of unresolved symbols. Throw out symbols which are
1378 Got file reading correct now. The files are all read while parsing
1379 the parameters. No creating of data structures to describe the linker
1380 command line. The symbol table is built up while reading the files.
1381 DSOs are handled now. -( -) handling is optimized.
1385 Linker read linker scripts everywhere. Handles --whole-archive. Recognizes
1386 --dynamic and --static. Collects defined and undefined symbols. Recognizes
1389 libebl now defines functions to call the callbacks. Add generic name handling
1390 in these new functions. Remove the code from readelf and call the new
1395 Start of linker. Basic argument parsing, finding of input files,
1396 linker script reading.
1400 Implement dwarf_get_fde_n(), dwarf_get_abbrev(), dwarf_get_abbrev_tag(),
1401 dwarf_get_abbrev_code(), dwarf_get_abbrev_children_flag(),
