1062 Fix check of various e_*size entries in elflint.
1064 Handle text output in asm_newsym.
1066 Finish checks in asm-tst3.
1070 Update to autoconf 2.53, automake 1.6, gettext 0.11+.
1072 Introduce *.sym files to restrict export from DSOs.
1074 Use attribute_hidden and internal_function to optimize DSO code.
1076 Add TLS definitions in elf.h and handle them in readelf.
1078 Fix bug in verdef section generation in ld.
1080 Add initial libasm code.
1084 Implement better hash size optimization heuristic in ld. It uses a formula
1085 taking number of tests into account.
1087 Lots of small bug fixes.
1089 Improve readelf output format. Respect various sh_link/sh_info values.
1090 Correctly print versioning information for symbol tables.
1094 Implement preprocessing of linker script. Recognize -z combreloc.
1098 Implement -z ignore|record for ld.
1100 Implement creating of .gnu.version_r and .gnu.version sections. The
1101 .gnu.version does not yet contain correct info for defined and versioned
1102 symbols (means .gnu.version_d is not yet implemented).
1104 Implement gelf_update_* functions to create versioning data.
1108 Add DT_RUNPATH/DT_RPATH entries to dynamic section. Create .plt and
1109 .rel.plt sections (completely). Add support for all four PLT related
1110 dynamic section entries. Add callback function for PLT creation.
1112 More tests in elflint. Add support for very strict checking which for
1113 now flags level 2 (deprecated features) usage.
1117 Create dynamic symbol table, dynamic string table, and hash table to ld.
1119 Add hash table histogram support to readelf.
1123 more work on elflint
1125 ld now creates the dynamic section and references it. Start adding entries
1130 Start implementing elflint.
1134 Fix handling of NOBITS sections in elf_getdata.
1136 Start implementing generation of executables and DSOs in ld.
1137 Generation of program header mostly done. Address computation done.
1138 Extension of linker script syntax.
1142 Implement section group handling in readelf.
1146 Implement section groups. This involved a lot of code moving. The
1147 new code is entirely untested since gas/gcc are currently not able to
1148 create section groups. ld works fine on files without section groups.
1152 Fix problem with adding more section in elf_newscn. The section pointers
1153 for the data buffers wasn't adjusted.
1155 Fix elf_getdata with nonzero second parameter. Correctly handle creation
1156 of internal data buffer for machines without unaligned access.
1160 Start adding support to selectively add sections. Includes support for
1162 Add --gc-sections/--no-gc-sections options.
1163 Add general section merging support.
1165 Fix a bug in section group support in strip.
1167 Fix some potential problems with hash value in dynamic hash implementation.
1171 section merging works in ld.
1175 Actually create data structures from version map file and use it to hide
1178 Implement -s -s for ld.
1182 Improve relocation table output in readelf. Avoid some crashes.
1183 Finish many section handling in readelf.
1185 Finish: finish implementation of ld -r. At least some simple tests pass.
1189 Fix a number of errors in ELF_C_WRITE handling.
1191 Almost finished implementation of ld -r. The data sections are all copied.
1192 Handling of symbol tables is missing.
1196 Handle DSO and archive input files correctly if -r option is given.
1198 Gracefully deal with no phdr in new file in libelf.
1199 Fix various small error handling problems.
1200 Don't mmap file for output unless the command says so.
1202 Add code to create ELF section header table to ld finalize routines.
1206 Fix some problems with recursive handling of archives in libelf.
1208 Improve messages printed by nm.
1210 Add symbol binding name handling to libebl. Fix section name handling in
1213 readelf and nm use more libebl functions.
1215 Handle XINDEX correctly in nm and string.
1217 Add first machine ld backend library (i386).
1218 Use it. Recognize -r and --shared. Avoid using -lxxx parameters for -r.
1219 Create ELF header in output file. Change mode of output file according to
1220 output file type. Reorganize callback initialization in ld.
1224 Fix some memory leaks in libelf.
1228 Implement reading version script. Both inside linker scripts and via the
1229 --version-script command line parameter. Uses the same code.
1230 What remains to be done is to implement a data structure which allows
1231 efficient matching against the version names to decide which pattern
1234 Beginning of output generation and output writing functions.
1238 Finish implementation for DSO input file handling. Implement rpath, runpath,
1239 and LD_LIBRARY_PATH handling.
1243 make handling of e_shnum overflow in libelf standard conforming
1245 ld now actually can handle DSOs in linker scripts. Handling of DT_RUNPATH,
1246 DT_RPATH, -rpath, -rpath-link still remains to be implemented.
1248 fix handling of -L parameters. Make actual use of the default_paths element.
1250 make re-definition of symbols in and from DSO compatible with existing linker
1254 more work on assigning input sections to output sections.
1256 Add gelf_xlatetof and gelf_xlatetom which were accidently left out.
1258 Fix memory handling of section headers.
1262 Add many-section support to ld. Add various new command line parameters.
1263 Allow pagesize to be specified in linker script or on the command line.
1264 Collect input sections in list for the output section according to the rules
1265 specified in the linker script.
1269 Fix some problems in the internal list handling which had the result
1270 that we didn't look for some of the unresolved symbols.
1272 Free some memory if we know we don't need it anymore.
1274 Optimize the list of unresolved symbols. Throw out symbols which are
1279 Got file reading correct now. The files are all read while parsing
1280 the parameters. No creating of data structures to describe the linker
1281 command line. The symbol table is built up while reading the files.
1282 DSOs are handled now. -( -) handling is optimized.
1286 Linker read linker scripts everywhere. Handles --whole-archive. Recognizes
1287 --dynamic and --static. Collects defined and undefined symbols. Recognizes
1290 libebl now defines functions to call the callbacks. Add generic name handling
1291 in these new functions. Remove the code from readelf and call the new
1296 Start of linker. Basic argument parsing, finding of input files,
1297 linker script reading.
1301 Implement dwarf_get_fde_n(), dwarf_get_abbrev(), dwarf_get_abbrev_tag(),
1302 dwarf_get_abbrev_code(), dwarf_get_abbrev_children_flag(),
