1016 Update to autoconf 2.53, automake 1.6, gettext 0.11+.
1018 Introduce *.sym files to restrict export from DSOs.
1020 Use attribute_hidden and internal_function to optimize DSO code.
1022 Add TLS definitions in elf.h and handle them in readelf.
1024 Fix bug in verdef section generation in ld.
1026 Add initial libasm code.
1030 Implement better hash size optimization heuristic in ld. It uses a formula
1031 taking number of tests into account.
1033 Lots of small bug fixes.
1035 Improve readelf output format. Respect various sh_link/sh_info values.
1036 Correctly print versioning information for symbol tables.
1040 Implement preprocessing of linker script. Recognize -z combreloc.
1044 Implement -z ignore|record for ld.
1046 Implement creating of .gnu.version_r and .gnu.version sections. The
1047 .gnu.version does not yet contain correct info for defined and versioned
1048 symbols (means .gnu.version_d is not yet implemented).
1050 Implement gelf_update_* functions to create versioning data.
1054 Add DT_RUNPATH/DT_RPATH entries to dynamic section. Create .plt and
1055 .rel.plt sections (completely). Add support for all four PLT related
1056 dynamic section entries. Add callback function for PLT creation.
1058 More tests in elflint. Add support for very strict checking which for
1059 now flags level 2 (deprecated features) usage.
1063 Create dynamic symbol table, dynamic string table, and hash table to ld.
1065 Add hash table histogram support to readelf.
1069 more work on elflint
1071 ld now creates the dynamic section and references it. Start adding entries
1076 Start implementing elflint.
1080 Fix handling of NOBITS sections in elf_getdata.
1082 Start implementing generation of executables and DSOs in ld.
1083 Generation of program header mostly done. Address computation done.
1084 Extension of linker script syntax.
1088 Implement section group handling in readelf.
1092 Implement section groups. This involved a lot of code moving. The
1093 new code is entirely untested since gas/gcc are currently not able to
1094 create section groups. ld works fine on files without section groups.
1098 Fix problem with adding more section in elf_newscn. The section pointers
1099 for the data buffers wasn't adjusted.
1101 Fix elf_getdata with nonzero second parameter. Correctly handle creation
1102 of internal data buffer for machines without unaligned access.
1106 Start adding support to selectively add sections. Includes support for
1108 Add --gc-sections/--no-gc-sections options.
1109 Add general section merging support.
1111 Fix a bug in section group support in strip.
1113 Fix some potential problems with hash value in dynamic hash implementation.
1117 section merging works in ld.
1121 Actually create data structures from version map file and use it to hide
1124 Implement -s -s for ld.
1128 Improve relocation table output in readelf. Avoid some crashes.
1129 Finish many section handling in readelf.
1131 Finish: finish implementation of ld -r. At least some simple tests pass.
1135 Fix a number of errors in ELF_C_WRITE handling.
1137 Almost finished implementation of ld -r. The data sections are all copied.
1138 Handling of symbol tables is missing.
1142 Handle DSO and archive input files correctly if -r option is given.
1144 Gracefully deal with no phdr in new file in libelf.
1145 Fix various small error handling problems.
1146 Don't mmap file for output unless the command says so.
1148 Add code to create ELF section header table to ld finalize routines.
1152 Fix some problems with recursive handling of archives in libelf.
1154 Improve messages printed by nm.
1156 Add symbol binding name handling to libebl. Fix section name handling in
1159 readelf and nm use more libebl functions.
1161 Handle XINDEX correctly in nm and string.
1163 Add first machine ld backend library (i386).
1164 Use it. Recognize -r and --shared. Avoid using -lxxx parameters for -r.
1165 Create ELF header in output file. Change mode of output file according to
1166 output file type. Reorganize callback initialization in ld.
1170 Fix some memory leaks in libelf.
1174 Implement reading version script. Both inside linker scripts and via the
1175 --version-script command line parameter. Uses the same code.
1176 What remains to be done is to implement a data structure which allows
1177 efficient matching against the version names to decide which pattern
1180 Beginning of output generation and output writing functions.
1184 Finish implementation for DSO input file handling. Implement rpath, runpath,
1185 and LD_LIBRARY_PATH handling.
1189 make handling of e_shnum overflow in libelf standard conforming
1191 ld now actually can handle DSOs in linker scripts. Handling of DT_RUNPATH,
1192 DT_RPATH, -rpath, -rpath-link still remains to be implemented.
1194 fix handling of -L parameters. Make actual use of the default_paths element.
1196 make re-definition of symbols in and from DSO compatible with existing linker
1200 more work on assigning input sections to output sections.
1202 Add gelf_xlatetof and gelf_xlatetom which were accidently left out.
1204 Fix memory handling of section headers.
1208 Add many-section support to ld. Add various new command line parameters.
1209 Allow pagesize to be specified in linker script or on the command line.
1210 Collect input sections in list for the output section according to the rules
1211 specified in the linker script.
1215 Fix some problems in the internal list handling which had the result
1216 that we didn't look for some of the unresolved symbols.
1218 Free some memory if we know we don't need it anymore.
1220 Optimize the list of unresolved symbols. Throw out symbols which are
1225 Got file reading correct now. The files are all read while parsing
1226 the parameters. No creating of data structures to describe the linker
1227 command line. The symbol table is built up while reading the files.
1228 DSOs are handled now. -( -) handling is optimized.
1232 Linker read linker scripts everywhere. Handles --whole-archive. Recognizes
1233 --dynamic and --static. Collects defined and undefined symbols. Recognizes
1236 libebl now defines functions to call the callbacks. Add generic name handling
1237 in these new functions. Remove the code from readelf and call the new
1242 Start of linker. Basic argument parsing, finding of input files,
1243 linker script reading.
1247 Implement dwarf_get_fde_n(), dwarf_get_abbrev(), dwarf_get_abbrev_tag(),
1248 dwarf_get_abbrev_code(), dwarf_get_abbrev_children_flag(),
