1021 Introduce *.sym files to restrict export from DSOs.
1023 Use attribute_hidden and internal_function to optimize DSO code.
1025 Add TLS definitions in elf.h and handle them in readelf.
1027 Fix bug in verdef section generation in ld.
1029 Add initial libasm code.
1033 Implement better hash size optimization heuristic in ld. It uses a formula
1034 taking number of tests into account.
1036 Lots of small bug fixes.
1038 Improve readelf output format. Respect various sh_link/sh_info values.
1039 Correctly print versioning information for symbol tables.
1043 Implement preprocessing of linker script. Recognize -z combreloc.
1047 Implement -z ignore|record for ld.
1049 Implement creating of .gnu.version_r and .gnu.version sections. The
1050 .gnu.version does not yet contain correct info for defined and versioned
1051 symbols (means .gnu.version_d is not yet implemented).
1053 Implement gelf_update_* functions to create versioning data.
1057 Add DT_RUNPATH/DT_RPATH entries to dynamic section. Create .plt and
1058 .rel.plt sections (completely). Add support for all four PLT related
1059 dynamic section entries. Add callback function for PLT creation.
1061 More tests in elflint. Add support for very strict checking which for
1062 now flags level 2 (deprecated features) usage.
1066 Create dynamic symbol table, dynamic string table, and hash table to ld.
1068 Add hash table histogram support to readelf.
1072 more work on elflint
1074 ld now creates the dynamic section and references it. Start adding entries
1079 Start implementing elflint.
1083 Fix handling of NOBITS sections in elf_getdata.
1085 Start implementing generation of executables and DSOs in ld.
1086 Generation of program header mostly done. Address computation done.
1087 Extension of linker script syntax.
1091 Implement section group handling in readelf.
1095 Implement section groups. This involved a lot of code moving. The
1096 new code is entirely untested since gas/gcc are currently not able to
1097 create section groups. ld works fine on files without section groups.
1101 Fix problem with adding more section in elf_newscn. The section pointers
1102 for the data buffers wasn't adjusted.
1104 Fix elf_getdata with nonzero second parameter. Correctly handle creation
1105 of internal data buffer for machines without unaligned access.
1109 Start adding support to selectively add sections. Includes support for
1111 Add --gc-sections/--no-gc-sections options.
1112 Add general section merging support.
1114 Fix a bug in section group support in strip.
1116 Fix some potential problems with hash value in dynamic hash implementation.
1120 section merging works in ld.
1124 Actually create data structures from version map file and use it to hide
1127 Implement -s -s for ld.
1131 Improve relocation table output in readelf. Avoid some crashes.
1132 Finish many section handling in readelf.
1134 Finish: finish implementation of ld -r. At least some simple tests pass.
1138 Fix a number of errors in ELF_C_WRITE handling.
1140 Almost finished implementation of ld -r. The data sections are all copied.
1141 Handling of symbol tables is missing.
1145 Handle DSO and archive input files correctly if -r option is given.
1147 Gracefully deal with no phdr in new file in libelf.
1148 Fix various small error handling problems.
1149 Don't mmap file for output unless the command says so.
1151 Add code to create ELF section header table to ld finalize routines.
1155 Fix some problems with recursive handling of archives in libelf.
1157 Improve messages printed by nm.
1159 Add symbol binding name handling to libebl. Fix section name handling in
1162 readelf and nm use more libebl functions.
1164 Handle XINDEX correctly in nm and string.
1166 Add first machine ld backend library (i386).
1167 Use it. Recognize -r and --shared. Avoid using -lxxx parameters for -r.
1168 Create ELF header in output file. Change mode of output file according to
1169 output file type. Reorganize callback initialization in ld.
1173 Fix some memory leaks in libelf.
1177 Implement reading version script. Both inside linker scripts and via the
1178 --version-script command line parameter. Uses the same code.
1179 What remains to be done is to implement a data structure which allows
1180 efficient matching against the version names to decide which pattern
1183 Beginning of output generation and output writing functions.
1187 Finish implementation for DSO input file handling. Implement rpath, runpath,
1188 and LD_LIBRARY_PATH handling.
1192 make handling of e_shnum overflow in libelf standard conforming
1194 ld now actually can handle DSOs in linker scripts. Handling of DT_RUNPATH,
1195 DT_RPATH, -rpath, -rpath-link still remains to be implemented.
1197 fix handling of -L parameters. Make actual use of the default_paths element.
1199 make re-definition of symbols in and from DSO compatible with existing linker
1203 more work on assigning input sections to output sections.
1205 Add gelf_xlatetof and gelf_xlatetom which were accidently left out.
1207 Fix memory handling of section headers.
1211 Add many-section support to ld. Add various new command line parameters.
1212 Allow pagesize to be specified in linker script or on the command line.
1213 Collect input sections in list for the output section according to the rules
1214 specified in the linker script.
1218 Fix some problems in the internal list handling which had the result
1219 that we didn't look for some of the unresolved symbols.
1221 Free some memory if we know we don't need it anymore.
1223 Optimize the list of unresolved symbols. Throw out symbols which are
1228 Got file reading correct now. The files are all read while parsing
1229 the parameters. No creating of data structures to describe the linker
1230 command line. The symbol table is built up while reading the files.
1231 DSOs are handled now. -( -) handling is optimized.
1235 Linker read linker scripts everywhere. Handles --whole-archive. Recognizes
1236 --dynamic and --static. Collects defined and undefined symbols. Recognizes
1239 libebl now defines functions to call the callbacks. Add generic name handling
1240 in these new functions. Remove the code from readelf and call the new
1245 Start of linker. Basic argument parsing, finding of input files,
1246 linker script reading.
1250 Implement dwarf_get_fde_n(), dwarf_get_abbrev(), dwarf_get_abbrev_tag(),
1251 dwarf_get_abbrev_code(), dwarf_get_abbrev_children_flag(),
