1102 Implement preprocessing of linker script. Recognize -z combreloc.
1106 Implement -z ignore|record for ld.
1108 Implement creating of .gnu.version_r and .gnu.version sections. The
1109 .gnu.version does not yet contain correct info for defined and versioned
1110 symbols (means .gnu.version_d is not yet implemented).
1112 Implement gelf_update_* functions to create versioning data.
1116 Add DT_RUNPATH/DT_RPATH entries to dynamic section. Create .plt and
1117 .rel.plt sections (completely). Add support for all four PLT related

1127 Add hash table histogram support to readelf.
1131 more work on elflint
1133 ld now creates the dynamic section and references it. Start adding entries

1145 Generation of program header mostly done. Address computation done.
1146 Extension of linker script syntax.
1150 Implement section group handling in readelf.
1154 Implement section groups. This involved a lot of code moving. The
1155 new code is entirely untested since gas/gcc are currently not able to
1156 create section groups. ld works fine on files without section groups.
1160 Fix problem with adding more section in elf_newscn. The section pointers
1161 for the data buffers wasn't adjusted.
1163 Fix elf_getdata with nonzero second parameter. Correctly handle creation
1164 of internal data buffer for machines without unaligned access.
1168 Start adding support to selectively add sections. Includes support for
1170 Add --gc-sections/--no-gc-sections options.
1171 Add general section merging support.
1173 Fix a bug in section group support in strip.

1179 section merging works in ld.
1183 Actually create data structures from version map file and use it to hide
1186 Implement -s -s for ld.
1190 Improve relocation table output in readelf. Avoid some crashes.
1191 Finish many section handling in readelf.
1193 Finish: finish implementation of ld -r. At least some simple tests pass.
1197 Fix a number of errors in ELF_C_WRITE handling.
1199 Almost finished implementation of ld -r. The data sections are all copied.
1200 Handling of symbol tables is missing.
1204 Handle DSO and archive input files correctly if -r option is given.
1206 Gracefully deal with no phdr in new file in libelf.
1207 Fix various small error handling problems.

1214 Fix some problems with recursive handling of archives in libelf.
1216 Improve messages printed by nm.
1218 Add symbol binding name handling to libebl. Fix section name handling in
1221 readelf and nm use more libebl functions.
1223 Handle XINDEX correctly in nm and string.
1225 Add first machine ld backend library (i386).
1226 Use it. Recognize -r and --shared. Avoid using -lxxx parameters for -r.
1227 Create ELF header in output file. Change mode of output file according to
1228 output file type. Reorganize callback initialization in ld.
1232 Fix some memory leaks in libelf.
1236 Implement reading version script. Both inside linker scripts and via the
1237 --version-script command line parameter. Uses the same code.
1238 What remains to be done is to implement a data structure which allows
1239 efficient matching against the version names to decide which pattern
1242 Beginning of output generation and output writing functions.
1246 Finish implementation for DSO input file handling. Implement rpath, runpath,
1247 and LD_LIBRARY_PATH handling.
1251 make handling of e_shnum overflow in libelf standard conforming
1253 ld now actually can handle DSOs in linker scripts. Handling of DT_RUNPATH,
1254 DT_RPATH, -rpath, -rpath-link still remains to be implemented.
1256 fix handling of -L parameters. Make actual use of the default_paths element.
1258 make re-definition of symbols in and from DSO compatible with existing linker
1262 more work on assigning input sections to output sections.
1264 Add gelf_xlatetof and gelf_xlatetom which were accidently left out.
1266 Fix memory handling of section headers.
1270 Add many-section support to ld. Add various new command line parameters.
1271 Allow pagesize to be specified in linker script or on the command line.
1272 Collect input sections in list for the output section according to the rules
1273 specified in the linker script.
1277 Fix some problems in the internal list handling which had the result
1278 that we didn't look for some of the unresolved symbols.
1280 Free some memory if we know we don't need it anymore.
1282 Optimize the list of unresolved symbols. Throw out symbols which are
1287 Got file reading correct now. The files are all read while parsing
1288 the parameters. No creating of data structures to describe the linker
1289 command line. The symbol table is built up while reading the files.
1290 DSOs are handled now. -( -) handling is optimized.
1294 Linker read linker scripts everywhere. Handles --whole-archive. Recognizes
1295 --dynamic and --static. Collects defined and undefined symbols. Recognizes
1298 libebl now defines functions to call the callbacks. Add generic name handling
1299 in these new functions. Remove the code from readelf and call the new
1304 Start of linker. Basic argument parsing, finding of input files,
1305 linker script reading.
1309 Implement dwarf_get_fde_n(), dwarf_get_abbrev(), dwarf_get_abbrev_tag(),
1310 dwarf_get_abbrev_code(), dwarf_get_abbrev_children_flag(),
