[PATCH 1/9] libdw: Add DWARF5 attributes. [PATCH 2/9] libdw: Add new DWARF5 tag constants. [PATCH 3/9] libdw: Add new DWARF5 character encodings. [PATCH 4/9] libdw: DWARF5 Add new DW_LANG codes and default lower [PATCH 5/9] libdw: Add dwarf_default_lower_bound. [PATCH 6/9] libdw: DWARF5 Add DW_CC_pass_by_reference and [PATCH 7/9] Handle DWARF5 defaulted member function encodings. [PATCH 8/9] libdw: Handle DWARF5 immutable, packed and shared in [PATCH 9/9] libdw: Add DW_MACRO constants and DW_MACRO_GNU This doesn't include the "hard" parts of handling the new DWARF5 unit headers, forms, expression operations, line tables and the new debug_names, etc. Some of that work can be found here: https://code.wildebeest.org/git/user/mjw/elfutils/commit/?h=mjw/DWARF5_UT_FORM but that is still very much a work in progress. I believe the above patches however are ready and I would like to include them in the next release. It has been 3 months since the last one, so it is time to do a new one soon. It would be nice to at least handle these easy parts of DWARF5 with elfutils 0.170. Cheers, Mark
