1110 Implement creating of .gnu.version_r and .gnu.version sections. The
1111 .gnu.version does not yet contain correct info for defined and versioned
1112 symbols (means .gnu.version_d is not yet implemented).
1114 Implement gelf_update_* functions to create versioning data.
1118 Add DT_RUNPATH/DT_RPATH entries to dynamic section. Create .plt and

1147 Generation of program header mostly done. Address computation done.
1148 Extension of linker script syntax.
1152 Implement section group handling in readelf.
1156 Implement section groups. This involved a lot of code moving. The
1157 new code is entirely untested since gas/gcc are currently not able to
1158 create section groups. ld works fine on files without section groups.
1162 Fix problem with adding more section in elf_newscn. The section pointers
1163 for the data buffers wasn't adjusted.
1165 Fix elf_getdata with nonzero second parameter. Correctly handle creation
1166 of internal data buffer for machines without unaligned access.

1195 Finish: finish implementation of ld -r. At least some simple tests pass.
1199 Fix a number of errors in ELF_C_WRITE handling.
1201 Almost finished implementation of ld -r. The data sections are all copied.

1216 Fix some problems with recursive handling of archives in libelf.
1218 Improve messages printed by nm.
1220 Add symbol binding name handling to libebl. Fix section name handling in
1223 readelf and nm use more libebl functions.
1225 Handle XINDEX correctly in nm and string.
1227 Add first machine ld backend library (i386).
1228 Use it. Recognize -r and --shared. Avoid using -lxxx parameters for -r.
1229 Create ELF header in output file. Change mode of output file according to
1230 output file type. Reorganize callback initialization in ld.
1234 Fix some memory leaks in libelf.
1238 Implement reading version script. Both inside linker scripts and via the
1239 --version-script command line parameter. Uses the same code.
1240 What remains to be done is to implement a data structure which allows
1241 efficient matching against the version names to decide which pattern
1244 Beginning of output generation and output writing functions.
1248 Finish implementation for DSO input file handling. Implement rpath, runpath,
1249 and LD_LIBRARY_PATH handling.
1253 make handling of e_shnum overflow in libelf standard conforming
1255 ld now actually can handle DSOs in linker scripts. Handling of DT_RUNPATH,
1256 DT_RPATH, -rpath, -rpath-link still remains to be implemented.
1258 fix handling of -L parameters. Make actual use of the default_paths element.
1260 make re-definition of symbols in and from DSO compatible with existing linker
1264 more work on assigning input sections to output sections.
1266 Add gelf_xlatetof and gelf_xlatetom which were accidently left out.
1268 Fix memory handling of section headers.
1272 Add many-section support to ld. Add various new command line parameters.
1273 Allow pagesize to be specified in linker script or on the command line.
1274 Collect input sections in list for the output section according to the rules
1275 specified in the linker script.
1279 Fix some problems in the internal list handling which had the result
1280 that we didn't look for some of the unresolved symbols.
1282 Free some memory if we know we don't need it anymore.
1284 Optimize the list of unresolved symbols. Throw out symbols which are
1289 Got file reading correct now. The files are all read while parsing
1290 the parameters. No creating of data structures to describe the linker
1291 command line. The symbol table is built up while reading the files.
1292 DSOs are handled now. -( -) handling is optimized.
1296 Linker read linker scripts everywhere. Handles --whole-archive. Recognizes
1297 --dynamic and --static. Collects defined and undefined symbols. Recognizes
1300 libebl now defines functions to call the callbacks. Add generic name handling
1301 in these new functions. Remove the code from readelf and call the new
1306 Start of linker. Basic argument parsing, finding of input files,
1307 linker script reading.
