3 DWARF5 and split dwarf, including GNU DebugFission, are supported now.
4 Data can be read from the new DWARF sections .debug_addr, .debug_line_str,

8 handled by existing functions (dwarf_getlocation*, dwarf_getsrclines,
9 dwarf_ranges, dwarf_form*, etc.) now returning the data from the new
10 sections and data formats. But some new functions have been added
11 to more easily get information about skeleton and split compile units
12 (dwarf_get_units and dwarf_cu_info), handle new attribute data
13 (dwarf_getabbrevattr_data) and to keep references to Dwarf_Dies
14 that might come from different sections or files (dwarf_die_addr_die).

1359 Handle XINDEX correctly in nm and string.
1361 Add first machine ld backend library (i386).
1362 Use it. Recognize -r and --shared. Avoid using -lxxx parameters for -r.
1363 Create ELF header in output file. Change mode of output file according to
1364 output file type. Reorganize callback initialization in ld.
1368 Fix some memory leaks in libelf.
1372 Implement reading version script. Both inside linker scripts and via the
1373 --version-script command line parameter. Uses the same code.
1374 What remains to be done is to implement a data structure which allows
1375 efficient matching against the version names to decide which pattern
1378 Beginning of output generation and output writing functions.

1383 and LD_LIBRARY_PATH handling.
1387 make handling of e_shnum overflow in libelf standard conforming
1389 ld now actually can handle DSOs in linker scripts. Handling of DT_RUNPATH,
1390 DT_RPATH, -rpath, -rpath-link still remains to be implemented.
1392 fix handling of -L parameters. Make actual use of the default_paths element.
1394 make re-definition of symbols in and from DSO compatible with existing linker
1398 more work on assigning input sections to output sections.
1400 Add gelf_xlatetof and gelf_xlatetom which were accidently left out.
1402 Fix memory handling of section headers.
1406 Add many-section support to ld. Add various new command line parameters.
1407 Allow pagesize to be specified in linker script or on the command line.
1408 Collect input sections in list for the output section according to the rules
1409 specified in the linker script.
1413 Fix some problems in the internal list handling which had the result
1414 that we didn't look for some of the unresolved symbols.
1416 Free some memory if we know we don't need it anymore.
1418 Optimize the list of unresolved symbols. Throw out symbols which are
1423 Got file reading correct now. The files are all read while parsing
1424 the parameters. No creating of data structures to describe the linker
1425 command line. The symbol table is built up while reading the files.
1426 DSOs are handled now. -( -) handling is optimized.
1430 Linker read linker scripts everywhere. Handles --whole-archive. Recognizes
1431 --dynamic and --static. Collects defined and undefined symbols. Recognizes
1434 libebl now defines functions to call the callbacks. Add generic name handling
1435 in these new functions. Remove the code from readelf and call the new
1440 Start of linker. Basic argument parsing, finding of input files,
1441 linker script reading.
