1051 section merging works in ld.
1055 Actually create data structures from version map file and use it to hide
1058 Implement -s -s for ld.
1062 Improve relocation table output in readelf. Avoid some crashes.
1063 Finish many section handling in readelf.
1065 Finish: finish implementation of ld -r. At least some simple tests pass.
1069 Fix a number of errors in ELF_C_WRITE handling.
1071 Almost finished implementation of ld -r. The data sections are all copied.
1072 Handling of symbol tables is missing.
1076 Handle DSO and archive input files correctly if -r option is given.
1078 Gracefully deal with no phdr in new file in libelf.
1079 Fix various small error handling problems.
1080 Don't mmap file for output unless the command says so.
1082 Add code to create ELF section header table to ld finalize routines.
1086 Fix some problems with recursive handling of archives in libelf.
1088 Improve messages printed by nm.
1090 Add symbol binding name handling to libebl. Fix section name handling in
1093 readelf and nm use more libebl functions.
1095 Handle XINDEX correctly in nm and string.
1097 Add first machine ld backend library (i386).
1098 Use it. Recognize -r and --shared. Avoid using -lxxx parameters for -r.
1099 Create ELF header in output file. Change mode of output file according to
1100 output file type. Reorganize callback initialization in ld.
1104 Fix some memory leaks in libelf.
1108 Implement reading version script. Both inside linker scripts and via the
1109 --version-script command line parameter. Uses the same code.
1110 What remains to be done is to implement a data structure which allows
1111 efficient matching against the version names to decide which pattern
1114 Beginning of output generation and output writing functions.
1118 Finish implementation for DSO input file handling. Implement rpath, runpath,
1119 and LD_LIBRARY_PATH handling.
1123 make handling of e_shnum overflow in libelf standard conforming
1125 ld now actually can handle DSOs in linker scripts. Handling of DT_RUNPATH,
1126 DT_RPATH, -rpath, -rpath-link still remains to be implemented.
1128 fix handling of -L parameters. Make actual use of the default_paths element.
1130 make re-definition of symbols in and from DSO compatible with existing linker
1134 more work on assigning input sections to output sections.
1136 Add gelf_xlatetof and gelf_xlatetom which were accidently left out.
1138 Fix memory handling of section headers.
1142 Add many-section support to ld. Add various new command line parameters.
1143 Allow pagesize to be specified in linker script or on the command line.
1144 Collect input sections in list for the output section according to the rules
1145 specified in the linker script.
1149 Fix some problems in the internal list handling which had the result
1150 that we didn't look for some of the unresolved symbols.
1152 Free some memory if we know we don't need it anymore.
1154 Optimize the list of unresolved symbols. Throw out symbols which are
1159 Got file reading correct now. The files are all read while parsing
1160 the parameters. No creating of data structures to describe the linker
1161 command line. The symbol table is built up while reading the files.
1162 DSOs are handled now. -( -) handling is optimized.
1166 Linker read linker scripts everywhere. Handles --whole-archive. Recognizes
1167 --dynamic and --static. Collects defined and undefined symbols. Recognizes
1170 libebl now defines functions to call the callbacks. Add generic name handling
1171 in these new functions. Remove the code from readelf and call the new
1176 Start of linker. Basic argument parsing, finding of input files,
1177 linker script reading.
1181 Implement dwarf_get_fde_n(), dwarf_get_abbrev(), dwarf_get_abbrev_tag(),
1182 dwarf_get_abbrev_code(), dwarf_get_abbrev_children_flag(),
1183 dwarf_get_abbrev_entry(), dwarf_get_fde_at_pc(), and tests for it.

1188 dwarf_get_fde_range(), dwarf_get_cie_info(), dwarf_get_fde_instr_bytes(),
1193 Make handling of binaries in other byte order work and add tests for it.
