1017 Use attribute_hidden and internal_function to optimize DSO code.
1019 Add TLS definitions in elf.h and handle them in readelf.
1021 Fix bug in verdef section generation in ld.
1023 Add initial libasm code.
1027 Implement better hash size optimization heuristic in ld. It uses a formula
1028 taking number of tests into account.
1030 Lots of small bug fixes.
1032 Improve readelf output format. Respect various sh_link/sh_info values.
1033 Correctly print versioning information for symbol tables.
1037 Implement preprocessing of linker script. Recognize -z combreloc.
1041 Implement -z ignore|record for ld.
1043 Implement creating of .gnu.version_r and .gnu.version sections. The
1044 .gnu.version does not yet contain correct info for defined and versioned
1045 symbols (means .gnu.version_d is not yet implemented).
1047 Implement gelf_update_* functions to create versioning data.
1051 Add DT_RUNPATH/DT_RPATH entries to dynamic section. Create .plt and
1052 .rel.plt sections (completely). Add support for all four PLT related
1053 dynamic section entries. Add callback function for PLT creation.
1055 More tests in elflint. Add support for very strict checking which for
1056 now flags level 2 (deprecated features) usage.
1060 Create dynamic symbol table, dynamic string table, and hash table to ld.
1062 Add hash table histogram support to readelf.
1066 more work on elflint
1068 ld now creates the dynamic section and references it. Start adding entries
1073 Start implementing elflint.
1077 Fix handling of NOBITS sections in elf_getdata.
1079 Start implementing generation of executables and DSOs in ld.
1080 Generation of program header mostly done. Address computation done.
1081 Extension of linker script syntax.
1085 Implement section group handling in readelf.
1089 Implement section groups. This involved a lot of code moving. The
1090 new code is entirely untested since gas/gcc are currently not able to
1091 create section groups. ld works fine on files without section groups.
1095 Fix problem with adding more section in elf_newscn. The section pointers
1096 for the data buffers wasn't adjusted.
1098 Fix elf_getdata with nonzero second parameter. Correctly handle creation
1099 of internal data buffer for machines without unaligned access.
1103 Start adding support to selectively add sections. Includes support for
1105 Add --gc-sections/--no-gc-sections options.
1106 Add general section merging support.
1108 Fix a bug in section group support in strip.
1110 Fix some potential problems with hash value in dynamic hash implementation.
1114 section merging works in ld.
1118 Actually create data structures from version map file and use it to hide
1121 Implement -s -s for ld.
1125 Improve relocation table output in readelf. Avoid some crashes.
1126 Finish many section handling in readelf.
1128 Finish: finish implementation of ld -r. At least some simple tests pass.
1132 Fix a number of errors in ELF_C_WRITE handling.
1134 Almost finished implementation of ld -r. The data sections are all copied.
1135 Handling of symbol tables is missing.
1139 Handle DSO and archive input files correctly if -r option is given.
1141 Gracefully deal with no phdr in new file in libelf.
1142 Fix various small error handling problems.
1143 Don't mmap file for output unless the command says so.
1145 Add code to create ELF section header table to ld finalize routines.
1149 Fix some problems with recursive handling of archives in libelf.
1151 Improve messages printed by nm.
1153 Add symbol binding name handling to libebl. Fix section name handling in
1156 readelf and nm use more libebl functions.
1158 Handle XINDEX correctly in nm and string.
1160 Add first machine ld backend library (i386).
1161 Use it. Recognize -r and --shared. Avoid using -lxxx parameters for -r.
1162 Create ELF header in output file. Change mode of output file according to
1163 output file type. Reorganize callback initialization in ld.
1167 Fix some memory leaks in libelf.
1171 Implement reading version script. Both inside linker scripts and via the
1172 --version-script command line parameter. Uses the same code.
1173 What remains to be done is to implement a data structure which allows
1174 efficient matching against the version names to decide which pattern
1177 Beginning of output generation and output writing functions.
1181 Finish implementation for DSO input file handling. Implement rpath, runpath,
1182 and LD_LIBRARY_PATH handling.
1186 make handling of e_shnum overflow in libelf standard conforming
1188 ld now actually can handle DSOs in linker scripts. Handling of DT_RUNPATH,
1189 DT_RPATH, -rpath, -rpath-link still remains to be implemented.
1191 fix handling of -L parameters. Make actual use of the default_paths element.
1193 make re-definition of symbols in and from DSO compatible with existing linker
1197 more work on assigning input sections to output sections.
1199 Add gelf_xlatetof and gelf_xlatetom which were accidently left out.
1201 Fix memory handling of section headers.
1205 Add many-section support to ld. Add various new command line parameters.
1206 Allow pagesize to be specified in linker script or on the command line.
1207 Collect input sections in list for the output section according to the rules
1208 specified in the linker script.
1212 Fix some problems in the internal list handling which had the result
1213 that we didn't look for some of the unresolved symbols.
1215 Free some memory if we know we don't need it anymore.
1217 Optimize the list of unresolved symbols. Throw out symbols which are
1222 Got file reading correct now. The files are all read while parsing
1223 the parameters. No creating of data structures to describe the linker
1224 command line. The symbol table is built up while reading the files.
1225 DSOs are handled now. -( -) handling is optimized.
1229 Linker read linker scripts everywhere. Handles --whole-archive. Recognizes
1230 --dynamic and --static. Collects defined and undefined symbols. Recognizes
1233 libebl now defines functions to call the callbacks. Add generic name handling
1234 in these new functions. Remove the code from readelf and call the new
1239 Start of linker. Basic argument parsing, finding of input files,
1240 linker script reading.
1244 Implement dwarf_get_fde_n(), dwarf_get_abbrev(), dwarf_get_abbrev_tag(),
1245 dwarf_get_abbrev_code(), dwarf_get_abbrev_children_flag(),
