From 748766b8f6237cd23b8e5f998fae39b31d2664d0 Mon Sep 17 00:00:00 2001 From: Tom Tromey Date: Sat, 9 Dec 2023 09:19:30 -0700 Subject: Add some new DW_IDX_* constants 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/ChangeLog 2023-12-10 Tom Tromey * dwarf2.def (DW_IDX_GNU_internal, DW_IDX_GNU_external): Comment.
