71 sections and data formats. But some new functions have been added
72 to more easily get information about skeleton and split compile units
73 (dwarf_get_units and dwarf_cu_info), handle new attribute data
74 (dwarf_getabbrevattr_data) and to keep references to Dwarf_Dies
75 that might come from different sections or files (dwarf_die_addr_die).
77 Not yet supported are .dwp (Dwarf Package) and .sup (Dwarf Supplementary)
78 files, the .debug_names index, the .debug_cu_index and .debug_tu_index

1420 Handle XINDEX correctly in nm and string.
1422 Add first machine ld backend library (i386).
1423 Use it. Recognize -r and --shared. Avoid using -lxxx parameters for -r.

1425 output file type. Reorganize callback initialization in ld.
1429 Fix some memory leaks in libelf.
1433 Implement reading version script. Both inside linker scripts and via the
1434 --version-script command line parameter. Uses the same code.

1436 efficient matching against the version names to decide which pattern
1439 Beginning of output generation and output writing functions.

1444 and LD_LIBRARY_PATH handling.
1448 make handling of e_shnum overflow in libelf standard conforming

1451 DT_RPATH, -rpath, -rpath-link still remains to be implemented.
1453 fix handling of -L parameters. Make actual use of the default_paths element.
1455 make re-definition of symbols in and from DSO compatible with existing linker
1459 more work on assigning input sections to output sections.
1461 Add gelf_xlatetof and gelf_xlatetom which were accidently left out.
1463 Fix memory handling of section headers.
1467 Add many-section support to ld. Add various new command line parameters.
1468 Allow pagesize to be specified in linker script or on the command line.
1469 Collect input sections in list for the output section according to the rules
1470 specified in the linker script.
1474 Fix some problems in the internal list handling which had the result
1475 that we didn't look for some of the unresolved symbols.
1477 Free some memory if we know we don't need it anymore.
1479 Optimize the list of unresolved symbols. Throw out symbols which are
1484 Got file reading correct now. The files are all read while parsing
1485 the parameters. No creating of data structures to describe the linker
1486 command line. The symbol table is built up while reading the files.
1487 DSOs are handled now. -( -) handling is optimized.
1491 Linker read linker scripts everywhere. Handles --whole-archive. Recognizes
1492 --dynamic and --static. Collects defined and undefined symbols. Recognizes
1495 libebl now defines functions to call the callbacks. Add generic name handling
1496 in these new functions. Remove the code from readelf and call the new
1501 Start of linker. Basic argument parsing, finding of input files,
1502 linker script reading.
