3 No functional changes compared to 0.171.
5 Various bug fixes in libdw and eu-readelf dealing with bad DWARF5 data.
6 Thanks to running the afl fuzzer on eu-readelf and various testcases.
8 eu-readelf -N is ~15% faster.
12 DWARF5 and split dwarf, including GNU DebugFission, are supported now.
13 Data can be read from the new DWARF sections .debug_addr, .debug_line_str,
14 .debug_loclists, .debug_str_offsets and .debug_rnglists. Plus the new
15 DWARF5 and GNU DebugFission encodings of the existing .debug sections.
16 Also in split DWARF .dwo (DWARF object) files. This support is mostly
17 handled by existing functions (dwarf_getlocation*, dwarf_getsrclines,
18 dwarf_ranges, dwarf_form*, etc.) now returning the data from the new
19 sections and data formats. But some new functions have been added
20 to more easily get information about skeleton and split compile units
21 (dwarf_get_units and dwarf_cu_info), handle new attribute data
22 (dwarf_getabbrevattr_data) and to keep references to Dwarf_Dies
23 that might come from different sections or files (dwarf_die_addr_die).
25 Not yet supported are .dwp (Dwarf Package) and .sup (Dwarf Supplementary)
26 files, the .debug_names index, the .debug_cu_index and .debug_tu_index
27 sections. Only a single .debug_info (and .debug_types) section are
30 readelf: Handle all new DWARF5 sections.

1299 Implement section groups. This involved a lot of code moving. The
1300 new code is entirely untested since gas/gcc are currently not able to
1301 create section groups. ld works fine on files without section groups.
1305 Fix problem with adding more section in elf_newscn. The section pointers
1306 for the data buffers wasn't adjusted.
1308 Fix elf_getdata with nonzero second parameter. Correctly handle creation

1366 readelf and nm use more libebl functions.
1368 Handle XINDEX correctly in nm and string.
1370 Add first machine ld backend library (i386).
1371 Use it. Recognize -r and --shared. Avoid using -lxxx parameters for -r.
1372 Create ELF header in output file. Change mode of output file according to
1373 output file type. Reorganize callback initialization in ld.
1377 Fix some memory leaks in libelf.
1381 Implement reading version script. Both inside linker scripts and via the
1382 --version-script command line parameter. Uses the same code.
1383 What remains to be done is to implement a data structure which allows
1384 efficient matching against the version names to decide which pattern
1387 Beginning of output generation and output writing functions.
1391 Finish implementation for DSO input file handling. Implement rpath, runpath,
1392 and LD_LIBRARY_PATH handling.
1396 make handling of e_shnum overflow in libelf standard conforming
1398 ld now actually can handle DSOs in linker scripts. Handling of DT_RUNPATH,
1399 DT_RPATH, -rpath, -rpath-link still remains to be implemented.
1401 fix handling of -L parameters. Make actual use of the default_paths element.
1403 make re-definition of symbols in and from DSO compatible with existing linker
1407 more work on assigning input sections to output sections.
1409 Add gelf_xlatetof and gelf_xlatetom which were accidently left out.
1411 Fix memory handling of section headers.
1415 Add many-section support to ld. Add various new command line parameters.
1416 Allow pagesize to be specified in linker script or on the command line.
1417 Collect input sections in list for the output section according to the rules
1418 specified in the linker script.
1422 Fix some problems in the internal list handling which had the result
1423 that we didn't look for some of the unresolved symbols.
1425 Free some memory if we know we don't need it anymore.
1427 Optimize the list of unresolved symbols. Throw out symbols which are
1432 Got file reading correct now. The files are all read while parsing
1433 the parameters. No creating of data structures to describe the linker
1434 command line. The symbol table is built up while reading the files.
1435 DSOs are handled now. -( -) handling is optimized.
1439 Linker read linker scripts everywhere. Handles --whole-archive. Recognizes
1440 --dynamic and --static. Collects defined and undefined symbols. Recognizes
1443 libebl now defines functions to call the callbacks. Add generic name handling
1444 in these new functions. Remove the code from readelf and call the new
1449 Start of linker. Basic argument parsing, finding of input files,
1450 linker script reading.
1454 Implement dwarf_get_fde_n(), dwarf_get_abbrev(), dwarf_get_abbrev_tag(),
