1029 Implement preprocessing of linker script. Recognize -z combreloc.
1033 Implement -z ignore|record for ld.
1035 Implement creating of .gnu.version_r and .gnu.version sections. The
1036 .gnu.version does not yet contain correct info for defined and versioned
1037 symbols (means .gnu.version_d is not yet implemented).
1039 Implement gelf_update_* functions to create versioning data.
1043 Add DT_RUNPATH/DT_RPATH entries to dynamic section. Create .plt and
1044 .rel.plt sections (completely). Add support for all four PLT related
1045 dynamic section entries. Add callback function for PLT creation.
1047 More tests in elflint. Add support for very strict checking which for
1048 now flags level 2 (deprecated features) usage.
1052 Create dynamic symbol table, dynamic string table, and hash table to ld.
1054 Add hash table histogram support to readelf.
1058 more work on elflint
1060 ld now creates the dynamic section and references it. Start adding entries
1065 Start implementing elflint.
1069 Fix handling of NOBITS sections in elf_getdata.
1071 Start implementing generation of executables and DSOs in ld.
1072 Generation of program header mostly done. Address computation done.
1073 Extension of linker script syntax.
1077 Implement section group handling in readelf.
1081 Implement section groups. This involved a lot of code moving. The
1082 new code is entirely untested since gas/gcc are currently not able to
1083 create section groups. ld works fine on files without section groups.
1087 Fix problem with adding more section in elf_newscn. The section pointers
1088 for the data buffers wasn't adjusted.
1090 Fix elf_getdata with nonzero second parameter. Correctly handle creation
1091 of internal data buffer for machines without unaligned access.
1095 Start adding support to selectively add sections. Includes support for
1097 Add --gc-sections/--no-gc-sections options.
1098 Add general section merging support.
1100 Fix a bug in section group support in strip.
1102 Fix some potential problems with hash value in dynamic hash implementation.
1106 section merging works in ld.
1110 Actually create data structures from version map file and use it to hide
1113 Implement -s -s for ld.
1117 Improve relocation table output in readelf. Avoid some crashes.
1118 Finish many section handling in readelf.
1120 Finish: finish implementation of ld -r. At least some simple tests pass.
1124 Fix a number of errors in ELF_C_WRITE handling.
1126 Almost finished implementation of ld -r. The data sections are all copied.
1127 Handling of symbol tables is missing.
1131 Handle DSO and archive input files correctly if -r option is given.
1133 Gracefully deal with no phdr in new file in libelf.
1134 Fix various small error handling problems.
1135 Don't mmap file for output unless the command says so.
1137 Add code to create ELF section header table to ld finalize routines.
1141 Fix some problems with recursive handling of archives in libelf.
1143 Improve messages printed by nm.
1145 Add symbol binding name handling to libebl. Fix section name handling in
1148 readelf and nm use more libebl functions.
1150 Handle XINDEX correctly in nm and string.
1152 Add first machine ld backend library (i386).
1153 Use it. Recognize -r and --shared. Avoid using -lxxx parameters for -r.
1154 Create ELF header in output file. Change mode of output file according to
1155 output file type. Reorganize callback initialization in ld.
1159 Fix some memory leaks in libelf.
1163 Implement reading version script. Both inside linker scripts and via the
1164 --version-script command line parameter. Uses the same code.
1165 What remains to be done is to implement a data structure which allows
1166 efficient matching against the version names to decide which pattern
1169 Beginning of output generation and output writing functions.
1173 Finish implementation for DSO input file handling. Implement rpath, runpath,
1174 and LD_LIBRARY_PATH handling.
1178 make handling of e_shnum overflow in libelf standard conforming
1180 ld now actually can handle DSOs in linker scripts. Handling of DT_RUNPATH,
1181 DT_RPATH, -rpath, -rpath-link still remains to be implemented.
1183 fix handling of -L parameters. Make actual use of the default_paths element.
1185 make re-definition of symbols in and from DSO compatible with existing linker
1189 more work on assigning input sections to output sections.
1191 Add gelf_xlatetof and gelf_xlatetom which were accidently left out.
1193 Fix memory handling of section headers.
1197 Add many-section support to ld. Add various new command line parameters.
1198 Allow pagesize to be specified in linker script or on the command line.
1199 Collect input sections in list for the output section according to the rules
1200 specified in the linker script.
1204 Fix some problems in the internal list handling which had the result
1205 that we didn't look for some of the unresolved symbols.
1207 Free some memory if we know we don't need it anymore.
1209 Optimize the list of unresolved symbols. Throw out symbols which are
1214 Got file reading correct now. The files are all read while parsing
1215 the parameters. No creating of data structures to describe the linker
1216 command line. The symbol table is built up while reading the files.
1217 DSOs are handled now. -( -) handling is optimized.
1221 Linker read linker scripts everywhere. Handles --whole-archive. Recognizes
1222 --dynamic and --static. Collects defined and undefined symbols. Recognizes
1225 libebl now defines functions to call the callbacks. Add generic name handling
1226 in these new functions. Remove the code from readelf and call the new
1231 Start of linker. Basic argument parsing, finding of input files,
1232 linker script reading.
1236 Implement dwarf_get_fde_n(), dwarf_get_abbrev(), dwarf_get_abbrev_tag(),
1237 dwarf_get_abbrev_code(), dwarf_get_abbrev_children_flag(),
1238 dwarf_get_abbrev_entry(), dwarf_get_fde_at_pc(), and tests for it.
1242 Implement dwarf_get_fde_list_eh(), dwarf_get_cie_of_fde(),
1243 dwarf_get_fde_range(), dwarf_get_cie_info(), dwarf_get_fde_instr_bytes(),
1248 Make handling of binaries in other byte order work and add tests for it.
