1077 Improve readelf output format. Respect various sh_link/sh_info values.
1078 Correctly print versioning information for symbol tables.
1082 Implement preprocessing of linker script. Recognize -z combreloc.
1086 Implement -z ignore|record for ld.
1088 Implement creating of .gnu.version_r and .gnu.version sections. The
1089 .gnu.version does not yet contain correct info for defined and versioned
1090 symbols (means .gnu.version_d is not yet implemented).
1092 Implement gelf_update_* functions to create versioning data.
1096 Add DT_RUNPATH/DT_RPATH entries to dynamic section. Create .plt and
1097 .rel.plt sections (completely). Add support for all four PLT related
1098 dynamic section entries. Add callback function for PLT creation.

1101 now flags level 2 (deprecated features) usage.
1105 Create dynamic symbol table, dynamic string table, and hash table to ld.
1107 Add hash table histogram support to readelf.
1111 more work on elflint
1113 ld now creates the dynamic section and references it. Start adding entries
1118 Start implementing elflint.
1122 Fix handling of NOBITS sections in elf_getdata.
1124 Start implementing generation of executables and DSOs in ld.
1125 Generation of program header mostly done. Address computation done.
1126 Extension of linker script syntax.
1130 Implement section group handling in readelf.
1134 Implement section groups. This involved a lot of code moving. The
1135 new code is entirely untested since gas/gcc are currently not able to
1136 create section groups. ld works fine on files without section groups.
1140 Fix problem with adding more section in elf_newscn. The section pointers
1141 for the data buffers wasn't adjusted.
1143 Fix elf_getdata with nonzero second parameter. Correctly handle creation
1144 of internal data buffer for machines without unaligned access.
1148 Start adding support to selectively add sections. Includes support for
1150 Add --gc-sections/--no-gc-sections options.
1151 Add general section merging support.
1153 Fix a bug in section group support in strip.
1155 Fix some potential problems with hash value in dynamic hash implementation.
1159 section merging works in ld.
1163 Actually create data structures from version map file and use it to hide
1166 Implement -s -s for ld.
1170 Improve relocation table output in readelf. Avoid some crashes.
1171 Finish many section handling in readelf.
1173 Finish: finish implementation of ld -r. At least some simple tests pass.
1177 Fix a number of errors in ELF_C_WRITE handling.
1179 Almost finished implementation of ld -r. The data sections are all copied.
1180 Handling of symbol tables is missing.
1184 Handle DSO and archive input files correctly if -r option is given.
1186 Gracefully deal with no phdr in new file in libelf.
1187 Fix various small error handling problems.
1188 Don't mmap file for output unless the command says so.

1194 Fix some problems with recursive handling of archives in libelf.
1196 Improve messages printed by nm.
1198 Add symbol binding name handling to libebl. Fix section name handling in
1201 readelf and nm use more libebl functions.
1203 Handle XINDEX correctly in nm and string.
1205 Add first machine ld backend library (i386).
1206 Use it. Recognize -r and --shared. Avoid using -lxxx parameters for -r.
1207 Create ELF header in output file. Change mode of output file according to
1208 output file type. Reorganize callback initialization in ld.
1212 Fix some memory leaks in libelf.
1216 Implement reading version script. Both inside linker scripts and via the
1217 --version-script command line parameter. Uses the same code.
1218 What remains to be done is to implement a data structure which allows
1219 efficient matching against the version names to decide which pattern
1222 Beginning of output generation and output writing functions.
1226 Finish implementation for DSO input file handling. Implement rpath, runpath,
1227 and LD_LIBRARY_PATH handling.
1231 make handling of e_shnum overflow in libelf standard conforming
1233 ld now actually can handle DSOs in linker scripts. Handling of DT_RUNPATH,
1234 DT_RPATH, -rpath, -rpath-link still remains to be implemented.
1236 fix handling of -L parameters. Make actual use of the default_paths element.
1238 make re-definition of symbols in and from DSO compatible with existing linker
1242 more work on assigning input sections to output sections.
1244 Add gelf_xlatetof and gelf_xlatetom which were accidently left out.
1246 Fix memory handling of section headers.
1250 Add many-section support to ld. Add various new command line parameters.
1251 Allow pagesize to be specified in linker script or on the command line.
1252 Collect input sections in list for the output section according to the rules
1253 specified in the linker script.
1257 Fix some problems in the internal list handling which had the result
1258 that we didn't look for some of the unresolved symbols.
1260 Free some memory if we know we don't need it anymore.
1262 Optimize the list of unresolved symbols. Throw out symbols which are
1267 Got file reading correct now. The files are all read while parsing
1268 the parameters. No creating of data structures to describe the linker
1269 command line. The symbol table is built up while reading the files.
1270 DSOs are handled now. -( -) handling is optimized.
1274 Linker read linker scripts everywhere. Handles --whole-archive. Recognizes
1275 --dynamic and --static. Collects defined and undefined symbols. Recognizes
1278 libebl now defines functions to call the callbacks. Add generic name handling
1279 in these new functions. Remove the code from readelf and call the new
1284 Start of linker. Basic argument parsing, finding of input files,
1285 linker script reading.
1289 Implement dwarf_get_fde_n(), dwarf_get_abbrev(), dwarf_get_abbrev_tag(),
1290 dwarf_get_abbrev_code(), dwarf_get_abbrev_children_flag(),
