1012 ld: correct compute symbol address in output file (section index was off by 1)
1014 ld: generate correct version info in dynsym without --export-dynamic and
1019 Fix check of various e_*size entries in elflint.
1021 Handle text output in asm_newsym.
1023 Finish checks in asm-tst3.
1027 Update to autoconf 2.53, automake 1.6, gettext 0.11+.
1029 Introduce *.sym files to restrict export from DSOs.
1031 Use attribute_hidden and internal_function to optimize DSO code.
1033 Add TLS definitions in elf.h and handle them in readelf.
1035 Fix bug in verdef section generation in ld.
1037 Add initial libasm code.
1041 Implement better hash size optimization heuristic in ld. It uses a formula
1042 taking number of tests into account.
1044 Lots of small bug fixes.
1046 Improve readelf output format. Respect various sh_link/sh_info values.
1047 Correctly print versioning information for symbol tables.
1051 Implement preprocessing of linker script. Recognize -z combreloc.
1055 Implement -z ignore|record for ld.
1057 Implement creating of .gnu.version_r and .gnu.version sections. The
1058 .gnu.version does not yet contain correct info for defined and versioned
1059 symbols (means .gnu.version_d is not yet implemented).
1061 Implement gelf_update_* functions to create versioning data.
1065 Add DT_RUNPATH/DT_RPATH entries to dynamic section. Create .plt and
1066 .rel.plt sections (completely). Add support for all four PLT related
1067 dynamic section entries. Add callback function for PLT creation.
1069 More tests in elflint. Add support for very strict checking which for
1070 now flags level 2 (deprecated features) usage.
1074 Create dynamic symbol table, dynamic string table, and hash table to ld.
1076 Add hash table histogram support to readelf.
1080 more work on elflint
1082 ld now creates the dynamic section and references it. Start adding entries
1087 Start implementing elflint.
1091 Fix handling of NOBITS sections in elf_getdata.
1093 Start implementing generation of executables and DSOs in ld.
1094 Generation of program header mostly done. Address computation done.
1095 Extension of linker script syntax.
1099 Implement section group handling in readelf.
1103 Implement section groups. This involved a lot of code moving. The
1104 new code is entirely untested since gas/gcc are currently not able to
1105 create section groups. ld works fine on files without section groups.
1109 Fix problem with adding more section in elf_newscn. The section pointers
1110 for the data buffers wasn't adjusted.
1112 Fix elf_getdata with nonzero second parameter. Correctly handle creation
1113 of internal data buffer for machines without unaligned access.
1117 Start adding support to selectively add sections. Includes support for
1119 Add --gc-sections/--no-gc-sections options.
1120 Add general section merging support.
1122 Fix a bug in section group support in strip.
1124 Fix some potential problems with hash value in dynamic hash implementation.
1128 section merging works in ld.
1132 Actually create data structures from version map file and use it to hide
1135 Implement -s -s for ld.
1139 Improve relocation table output in readelf. Avoid some crashes.
1140 Finish many section handling in readelf.
1142 Finish: finish implementation of ld -r. At least some simple tests pass.
1146 Fix a number of errors in ELF_C_WRITE handling.
1148 Almost finished implementation of ld -r. The data sections are all copied.
1149 Handling of symbol tables is missing.
1153 Handle DSO and archive input files correctly if -r option is given.
1155 Gracefully deal with no phdr in new file in libelf.
1156 Fix various small error handling problems.
1157 Don't mmap file for output unless the command says so.
1159 Add code to create ELF section header table to ld finalize routines.
1163 Fix some problems with recursive handling of archives in libelf.
1165 Improve messages printed by nm.
1167 Add symbol binding name handling to libebl. Fix section name handling in
1170 readelf and nm use more libebl functions.
1172 Handle XINDEX correctly in nm and string.
1174 Add first machine ld backend library (i386).
1175 Use it. Recognize -r and --shared. Avoid using -lxxx parameters for -r.
1176 Create ELF header in output file. Change mode of output file according to
1177 output file type. Reorganize callback initialization in ld.
1181 Fix some memory leaks in libelf.
1185 Implement reading version script. Both inside linker scripts and via the
1186 --version-script command line parameter. Uses the same code.
1187 What remains to be done is to implement a data structure which allows
1188 efficient matching against the version names to decide which pattern
1191 Beginning of output generation and output writing functions.
1195 Finish implementation for DSO input file handling. Implement rpath, runpath,
1196 and LD_LIBRARY_PATH handling.
1200 make handling of e_shnum overflow in libelf standard conforming
1202 ld now actually can handle DSOs in linker scripts. Handling of DT_RUNPATH,
1203 DT_RPATH, -rpath, -rpath-link still remains to be implemented.
1205 fix handling of -L parameters. Make actual use of the default_paths element.
1207 make re-definition of symbols in and from DSO compatible with existing linker
1211 more work on assigning input sections to output sections.
1213 Add gelf_xlatetof and gelf_xlatetom which were accidently left out.
1215 Fix memory handling of section headers.
1219 Add many-section support to ld. Add various new command line parameters.
1220 Allow pagesize to be specified in linker script or on the command line.
1221 Collect input sections in list for the output section according to the rules
1222 specified in the linker script.
1226 Fix some problems in the internal list handling which had the result
1227 that we didn't look for some of the unresolved symbols.
1229 Free some memory if we know we don't need it anymore.
1231 Optimize the list of unresolved symbols. Throw out symbols which are
1236 Got file reading correct now. The files are all read while parsing
1237 the parameters. No creating of data structures to describe the linker
1238 command line. The symbol table is built up while reading the files.
1239 DSOs are handled now. -( -) handling is optimized.
1243 Linker read linker scripts everywhere. Handles --whole-archive. Recognizes
1244 --dynamic and --static. Collects defined and undefined symbols. Recognizes
1247 libebl now defines functions to call the callbacks. Add generic name handling
1248 in these new functions. Remove the code from readelf and call the new
1253 Start of linker. Basic argument parsing, finding of input files,
1254 linker script reading.
1258 Implement dwarf_get_fde_n(), dwarf_get_abbrev(), dwarf_get_abbrev_tag(),
