990 libelf: implement {gelf,elf32,elf64}_checksum
992 libelf: optimze DSO: fewer relocations, fewer PLTs
996 ld: use correct section header string table index; write correct index
998 add dependencies for *.sym files
1002 libelf: add elf_getshnum and elf_getshstrndx
1004 libebl: update section type name function
1006 elflint: tons of fixes wrt large number of sections. New tests in this area.
1007 Same amount of other bug fixes.
1009 size, strip, nm: better support for large number of sections. Including
1010 using correct section header string table
1012 libasm: correctly create data structures for large number of sections
1014 new tests asm-tst4 and asm-tst5 to check large number of sections
1016 libasm: implement section group generation
1018 elflint: more tests on section groups. Improve performance on existing
1023 ld: add undefined symbols to dynamic symbol table if --export-dynamic is
1026 ld: fix value of e_entry
1030 elflint: print section names in error messages
1032 elflint: mustn't warn about multiple DT_NULL
1034 ld: don't emit all symbols if --export-dynamic is not given
1036 ld: correct compute symbol address in output file (section index was off by 1)
1038 ld: generate correct version info in dynsym without --export-dynamic and
1043 Fix check of various e_*size entries in elflint.
1045 Handle text output in asm_newsym.
1047 Finish checks in asm-tst3.
1051 Update to autoconf 2.53, automake 1.6, gettext 0.11+.
1053 Introduce *.sym files to restrict export from DSOs.
1055 Use attribute_hidden and internal_function to optimize DSO code.
1057 Add TLS definitions in elf.h and handle them in readelf.
1059 Fix bug in verdef section generation in ld.
1061 Add initial libasm code.
1065 Implement better hash size optimization heuristic in ld. It uses a formula
1066 taking number of tests into account.
1068 Lots of small bug fixes.
1070 Improve readelf output format. Respect various sh_link/sh_info values.
1071 Correctly print versioning information for symbol tables.
1075 Implement preprocessing of linker script. Recognize -z combreloc.
1079 Implement -z ignore|record for ld.
1081 Implement creating of .gnu.version_r and .gnu.version sections. The
1082 .gnu.version does not yet contain correct info for defined and versioned
1083 symbols (means .gnu.version_d is not yet implemented).
1085 Implement gelf_update_* functions to create versioning data.
1089 Add DT_RUNPATH/DT_RPATH entries to dynamic section. Create .plt and
1090 .rel.plt sections (completely). Add support for all four PLT related
1091 dynamic section entries. Add callback function for PLT creation.
1093 More tests in elflint. Add support for very strict checking which for
1094 now flags level 2 (deprecated features) usage.
1098 Create dynamic symbol table, dynamic string table, and hash table to ld.
1100 Add hash table histogram support to readelf.
1104 more work on elflint
1106 ld now creates the dynamic section and references it. Start adding entries
1111 Start implementing elflint.
1115 Fix handling of NOBITS sections in elf_getdata.
1117 Start implementing generation of executables and DSOs in ld.
1118 Generation of program header mostly done. Address computation done.
1119 Extension of linker script syntax.
1123 Implement section group handling in readelf.
1127 Implement section groups. This involved a lot of code moving. The
1128 new code is entirely untested since gas/gcc are currently not able to
1129 create section groups. ld works fine on files without section groups.
1133 Fix problem with adding more section in elf_newscn. The section pointers
1134 for the data buffers wasn't adjusted.
1136 Fix elf_getdata with nonzero second parameter. Correctly handle creation
1137 of internal data buffer for machines without unaligned access.
1141 Start adding support to selectively add sections. Includes support for
1143 Add --gc-sections/--no-gc-sections options.
1144 Add general section merging support.
1146 Fix a bug in section group support in strip.
1148 Fix some potential problems with hash value in dynamic hash implementation.
1152 section merging works in ld.
1156 Actually create data structures from version map file and use it to hide
1159 Implement -s -s for ld.
1163 Improve relocation table output in readelf. Avoid some crashes.
1164 Finish many section handling in readelf.
1166 Finish: finish implementation of ld -r. At least some simple tests pass.
1170 Fix a number of errors in ELF_C_WRITE handling.
1172 Almost finished implementation of ld -r. The data sections are all copied.
1173 Handling of symbol tables is missing.
1177 Handle DSO and archive input files correctly if -r option is given.
1179 Gracefully deal with no phdr in new file in libelf.
1180 Fix various small error handling problems.
1181 Don't mmap file for output unless the command says so.
1183 Add code to create ELF section header table to ld finalize routines.
1187 Fix some problems with recursive handling of archives in libelf.
1189 Improve messages printed by nm.
1191 Add symbol binding name handling to libebl. Fix section name handling in
1194 readelf and nm use more libebl functions.
1196 Handle XINDEX correctly in nm and string.
1198 Add first machine ld backend library (i386).
1199 Use it. Recognize -r and --shared. Avoid using -lxxx parameters for -r.
1200 Create ELF header in output file. Change mode of output file according to
1201 output file type. Reorganize callback initialization in ld.
1205 Fix some memory leaks in libelf.
1209 Implement reading version script. Both inside linker scripts and via the
1210 --version-script command line parameter. Uses the same code.
1211 What remains to be done is to implement a data structure which allows
1212 efficient matching against the version names to decide which pattern
1215 Beginning of output generation and output writing functions.
1219 Finish implementation for DSO input file handling. Implement rpath, runpath,
1220 and LD_LIBRARY_PATH handling.
1224 make handling of e_shnum overflow in libelf standard conforming
1226 ld now actually can handle DSOs in linker scripts. Handling of DT_RUNPATH,
1227 DT_RPATH, -rpath, -rpath-link still remains to be implemented.
1229 fix handling of -L parameters. Make actual use of the default_paths element.
1231 make re-definition of symbols in and from DSO compatible with existing linker
1235 more work on assigning input sections to output sections.
1237 Add gelf_xlatetof and gelf_xlatetom which were accidently left out.
1239 Fix memory handling of section headers.
1243 Add many-section support to ld. Add various new command line parameters.
1244 Allow pagesize to be specified in linker script or on the command line.
1245 Collect input sections in list for the output section according to the rules
1246 specified in the linker script.
1250 Fix some problems in the internal list handling which had the result
1251 that we didn't look for some of the unresolved symbols.
1253 Free some memory if we know we don't need it anymore.
1255 Optimize the list of unresolved symbols. Throw out symbols which are
1260 Got file reading correct now. The files are all read while parsing
1261 the parameters. No creating of data structures to describe the linker
1262 command line. The symbol table is built up while reading the files.
1263 DSOs are handled now. -( -) handling is optimized.
1267 Linker read linker scripts everywhere. Handles --whole-archive. Recognizes
1268 --dynamic and --static. Collects defined and undefined symbols. Recognizes
1271 libebl now defines functions to call the callbacks. Add generic name handling
1272 in these new functions. Remove the code from readelf and call the new
1277 Start of linker. Basic argument parsing, finding of input files,
1278 linker script reading.
1282 Implement dwarf_get_fde_n(), dwarf_get_abbrev(), dwarf_get_abbrev_tag(),
1283 dwarf_get_abbrev_code(), dwarf_get_abbrev_children_flag(),
