Subject: [PATCH 04/13] Use gdb_bfd_sections in get_stap_base_address
Date: Fri, 28 Aug 2020 10:23:40 -0600 [thread overview]
Message-ID: <20200828162349.987-5-tom@tromey.com> (raw)
In-Reply-To: <20200828162349.987-1-tom@tromey.com>
This changes get_stap_base_address to avoid bfd_map_over_sections, in
favor of iteration.
gdb/ChangeLog
2020-08-28 Tom Tromey <tom@tromey.com>
* stap-probe.c (get_stap_base_address_1): Remove.
(get_stap_base_address): Use foreach.
