I've reimplemented the .debug_names code in GDB -- it was quite far from being correct, and the new implementation is much closer to what is specified by DWARF.
However, the new writer in GDB needs to emit some symbol properties, so that the reader can be fully functional. This patch adds a few new DW_IDX_* constants, and tries to document the existing extensions as well. (My patch series add more documentation of these to the GDB manual as well.) --- include/dwarf2.def | 9 +++++++++ 1 file changed, 9 insertions(+) diff --git a/include/dwarf2.def b/include/dwarf2.def index 7ab3ee611fd4..75b75d901884 100644 --- a/include/dwarf2.def +++ b/include/dwarf2.def @@ -802,8 +802,17 @@ DW_IDX (DW_IDX_parent, 4) DW_IDX (DW_IDX_type_hash, 5) DW_IDX_DUP (DW_IDX_lo_user, 0x2000) DW_IDX (DW_IDX_hi_user, 0x3fff) +/* Internal linkage.
