[PATCH 1/9] libdw: Add DWARF5 attributes.
- From: Mark Wielaard <mark at klomp dot org>
- To: elfutils-devel at sourceware dot org
- Cc: Mark Wielaard <mark at klomp dot org>
- Date: Thu, 27 Jul 2017 00:07:38 +0200
- Subject: [PATCH 1/9] libdw: Add DWARF5 attributes.
- Authentication-results: sourceware.org; auth=none
- References: <1501106866-5846-1-git-send-email-mark@klomp.org>
Add new DWARF5 attribute constant names to the attributes enum.
Also add reserved comments between non-consecutive (reserved) numbers.
Remove DW_AT_subscr_data, DW_AT_element_list and DW_AT_member from the
enum list and turn them into compatibility defines because they are
not part of DWARF2+. That way code that directly references them still
compiles but they won't show up in known-dwarf.h.
