1057 Actually create data structures from version map file and use it to hide
1060 Implement -s -s for ld.
1064 Improve relocation table output in readelf. Avoid some crashes.
1065 Finish many section handling in readelf.
1067 Finish: finish implementation of ld -r. At least some simple tests pass.
1071 Fix a number of errors in ELF_C_WRITE handling.
1073 Almost finished implementation of ld -r. The data sections are all copied.
1074 Handling of symbol tables is missing.
1078 Handle DSO and archive input files correctly if -r option is given.
1080 Gracefully deal with no phdr in new file in libelf.
1081 Fix various small error handling problems.
1082 Don't mmap file for output unless the command says so.
1084 Add code to create ELF section header table to ld finalize routines.
1088 Fix some problems with recursive handling of archives in libelf.
1090 Improve messages printed by nm.
1092 Add symbol binding name handling to libebl. Fix section name handling in
1095 readelf and nm use more libebl functions.
1097 Handle XINDEX correctly in nm and string.
1099 Add first machine ld backend library (i386).
1100 Use it. Recognize -r and --shared. Avoid using -lxxx parameters for -r.
1101 Create ELF header in output file. Change mode of output file according to
1102 output file type. Reorganize callback initialization in ld.
1106 Fix some memory leaks in libelf.
1110 Implement reading version script. Both inside linker scripts and via the
1111 --version-script command line parameter. Uses the same code.
1112 What remains to be done is to implement a data structure which allows
1113 efficient matching against the version names to decide which pattern
1116 Beginning of output generation and output writing functions.
1120 Finish implementation for DSO input file handling. Implement rpath, runpath,
1121 and LD_LIBRARY_PATH handling.
1125 make handling of e_shnum overflow in libelf standard conforming
1127 ld now actually can handle DSOs in linker scripts. Handling of DT_RUNPATH,
1128 DT_RPATH, -rpath, -rpath-link still remains to be implemented.
1130 fix handling of -L parameters. Make actual use of the default_paths element.
1132 make re-definition of symbols in and from DSO compatible with existing linker
1136 more work on assigning input sections to output sections.
1138 Add gelf_xlatetof and gelf_xlatetom which were accidently left out.
1140 Fix memory handling of section headers.
1144 Add many-section support to ld. Add various new command line parameters.
1145 Allow pagesize to be specified in linker script or on the command line.
1146 Collect input sections in list for the output section according to the rules
1147 specified in the linker script.
1151 Fix some problems in the internal list handling which had the result
1152 that we didn't look for some of the unresolved symbols.
1154 Free some memory if we know we don't need it anymore.
1156 Optimize the list of unresolved symbols. Throw out symbols which are
1161 Got file reading correct now. The files are all read while parsing
1162 the parameters. No creating of data structures to describe the linker
1163 command line. The symbol table is built up while reading the files.
1164 DSOs are handled now. -( -) handling is optimized.
1168 Linker read linker scripts everywhere. Handles --whole-archive. Recognizes
1169 --dynamic and --static. Collects defined and undefined symbols. Recognizes
1172 libebl now defines functions to call the callbacks. Add generic name handling
1173 in these new functions. Remove the code from readelf and call the new
1178 Start of linker. Basic argument parsing, finding of input files,
1179 linker script reading.
1183 Implement dwarf_get_fde_n(), dwarf_get_abbrev(), dwarf_get_abbrev_tag(),
