11 or .debug_frame sections (which can be read without needing a DIE

24 Thanks to running the afl fuzzer on eu-readelf and various testcases.
26 eu-readelf -N is ~15% faster.
30 DWARF5 and split dwarf, including GNU DebugFission, are supported now.
31 Data can be read from the new DWARF sections .debug_addr, .debug_line_str,
32 .debug_loclists, .debug_str_offsets and .debug_rnglists. Plus the new
33 DWARF5 and GNU DebugFission encodings of the existing .debug sections.
34 Also in split DWARF .dwo (DWARF object) files. This support is mostly
35 handled by existing functions (dwarf_getlocation*, dwarf_getsrclines,
36 dwarf_ranges, dwarf_form*, etc.) now returning the data from the new
37 sections and data formats. But some new functions have been added
38 to more easily get information about skeleton and split compile units
39 (dwarf_get_units and dwarf_cu_info), handle new attribute data
40 (dwarf_getabbrevattr_data) and to keep references to Dwarf_Dies
41 that might come from different sections or files (dwarf_die_addr_die).
43 Not yet supported are .dwp (Dwarf Package) and .sup (Dwarf Supplementary)
44 files, the .debug_names index, the .debug_cu_index and .debug_tu_index
45 sections. Only a single .debug_info (and .debug_types) section are

1391 output file type. Reorganize callback initialization in ld.
1395 Fix some memory leaks in libelf.
1399 Implement reading version script. Both inside linker scripts and via the
1400 --version-script command line parameter. Uses the same code.

1410 and LD_LIBRARY_PATH handling.
1414 make handling of e_shnum overflow in libelf standard conforming

1417 DT_RPATH, -rpath, -rpath-link still remains to be implemented.
1419 fix handling of -L parameters. Make actual use of the default_paths element.
1421 make re-definition of symbols in and from DSO compatible with existing linker
1425 more work on assigning input sections to output sections.
1427 Add gelf_xlatetof and gelf_xlatetom which were accidently left out.
1429 Fix memory handling of section headers.
1433 Add many-section support to ld. Add various new command line parameters.
1434 Allow pagesize to be specified in linker script or on the command line.
1435 Collect input sections in list for the output section according to the rules
1436 specified in the linker script.
1440 Fix some problems in the internal list handling which had the result
1441 that we didn't look for some of the unresolved symbols.
1443 Free some memory if we know we don't need it anymore.
1445 Optimize the list of unresolved symbols. Throw out symbols which are
1450 Got file reading correct now. The files are all read while parsing
1451 the parameters. No creating of data structures to describe the linker
1452 command line. The symbol table is built up while reading the files.
1453 DSOs are handled now. -( -) handling is optimized.
1457 Linker read linker scripts everywhere. Handles --whole-archive. Recognizes
1458 --dynamic and --static. Collects defined and undefined symbols. Recognizes
