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.
