| Version 0.171 |
| |
| DWARF5 and split dwarf, including GNU DebugFission, are supported now. |
| Data can be read from the new DWARF sections .debug_addr, .debug_line_str, |
| .debug_loclists, .debug_str_offsets and .debug_rnglists. Plus the new |
| DWARF5 and GNU DebugFission encodings of the existing .debug sections. |
| Also in split DWARF .dwo (DWARF object) files. This support is mostly |
| handled by existing functions (dwarf_getlocation*, dwarf_getsrclines, |
| dwarf_ranges, dwarf_form*, etc.) now returning the data from the new |
| sections and data formats. But some new functions have been added |
| to more easily get information about skeleton and split compile units |
| (dwarf_get_units and dwarf_cu_info), handle new attribute data |
| (dwarf_getabbrevattr_data) and to keep references to Dwarf_Dies |
| that might come from different sections or files (dwarf_die_addr_die). |
| |
| Not yet supported are .dwp (Dwarf Package) and .sup (Dwarf Supplementary) |
| files, the .debug_names index, the .debug_cu_index and .debug_tu_index |
| sections. Only a single .debug_info (and .debug_types) section are |
| currently handled. |

| Implement creating of .gnu.version_r and .gnu.version sections. The |
| .gnu.version does not yet contain correct info for defined and versioned |
| symbols (means .gnu.version_d is not yet implemented). |
| |
| Implement gelf_update_* functions to create versioning data. |
| |
| Version 0.34: |
| |
| Add DT_RUNPATH/DT_RPATH entries to dynamic section. Create .plt and |
| .rel.plt sections (completely). Add support for all four PLT related |
| dynamic section entries. Add callback function for PLT creation. |

| Implement section group handling in readelf. |
| |
| Version 0.29: |
| |
| Implement section groups. This involved a lot of code moving. The |
| new code is entirely untested since gas/gcc are currently not able to |
| create section groups. ld works fine on files without section groups. |
| |
| Version 0.28: |
| |
| Fix problem with adding more section in elf_newscn. The section pointers |
| for the data buffers wasn't adjusted. |
| |

| |
| Handle DSO and archive input files correctly if -r option is given. |
| |
| Gracefully deal with no phdr in new file in libelf. |

| libebl. |
| |
| readelf and nm use more libebl functions. |
| |
| Handle XINDEX correctly in nm and string. |
| |
| Add first machine ld backend library (i386). |
| Use it. Recognize -r and --shared. Avoid using -lxxx parameters for -r. |

| output file type. Reorganize callback initialization in ld. |
| |
| Version 0.20: |
| |
| Fix some memory leaks in libelf. |

| Version 0.19: |
| |
| Implement reading version script. Both inside linker scripts and via the |
| --version-script command line parameter. Uses the same code. |
| What remains to be done is to implement a data structure which allows |
| efficient matching against the version names to decide which pattern |
| matches. |
| |
| Beginning of output generation and output writing functions. |
| |
| Version 0.18: |
| |
| Finish implementation for DSO input file handling. Implement rpath, runpath, |
| and LD_LIBRARY_PATH handling. |
| |
| Version 0.17: |
| |
| make handling of e_shnum overflow in libelf standard conforming |
| |
| ld now actually can handle DSOs in linker scripts. Handling of DT_RUNPATH, |
| DT_RPATH, -rpath, -rpath-link still remains to be implemented. |
| |
| fix handling of -L parameters. Make actual use of the default_paths element. |
| |
| make re-definition of symbols in and from DSO compatible with existing linker |

| that we didn't look for some of the unresolved symbols. |
| |
| Free some memory if we know we don't need it anymore. |
| |
| Optimize the list of unresolved symbols. Throw out symbols which are |
| meanwhile resolved. |
| |
| Version 0.13: |
| |
| Got file reading correct now. The files are all read while parsing |
| the parameters. No creating of data structures to describe the linker |
| command line. The symbol table is built up while reading the files. |
| DSOs are handled now. -( -) handling is optimized. |
| |
| Version 0.12: |
| |
| Linker read linker scripts everywhere. Handles --whole-archive. Recognizes |
| --dynamic and --static. Collects defined and undefined symbols. Recognizes |
| conflicts. |
| |
| libebl now defines functions to call the callbacks. Add generic name handling |
| in these new functions. Remove the code from readelf and call the new |
| functions. |
