|
|
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. |
|
|
|
readelf: Handle all new DWARF5 sections. |
|
--debug-dump=info+ will show split unit DIEs when found. |
|
--dwarf-skeleton can be used when inspecting a .dwo file. |
|
Recognizes GNU locviews with --debug-dump=loc. |
|
|
|
libdw: New functions dwarf_die_addr_die, dwarf_get_units, |
|
dwarf_getabbrevattr_data and dwarf_cu_info. |
|
libdw will now try to resolve the alt file on first use of |
|
an alt attribute FORM when not set yet with dwarf_set_alt. |
|
dwarf_aggregate_size() now works with multi-dimensional arrays. |

Handle XINDEX correctly in nm and string. |
|
|
|
Add first machine ld backend library (i386). |
