Subject: [PATCH 04/17] Add some new DW_IDX_* values
Date: Sun, 10 Dec 2023 09:44:53 -0700	[thread overview]
Message-ID: <20231210-debug-names-fix-v1-4-a8f6d2525018@tromey.com> (raw)
In-Reply-To: <20231210-debug-names-fix-v1-0-a8f6d2525018@tromey.com>

The new .debug_names 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.  (I will add more documentation of these to the
GDB manual as well.)
