Subject: [PATCH 1/2] Use gdb_bfd_get_full_section_contents in auto-load.c
Date: Thu, 17 Oct 2024 18:02:37 -0600	[thread overview]
Message-ID: <20241017-fix-race-pr-symtab-31626-v1-1-3a53459e9651@tromey.com> (raw)
In-Reply-To: <20241017-fix-race-pr-symtab-31626-v1-0-3a53459e9651@tromey.com>

This changes auto-load.c ot use gdb_bfd_get_full_section_contents.
This shouldn't change any behavior, but makes it easier to add locking
in a subsequent patch.
