Subject: [RFA v2 11/17] Use gdb::unique_ptr in elf_read_minimal_symbols
Date: Thu, 13 Oct 2016 21:11:00 -0000 [thread overview]
Message-ID: <1476393012-29987-12-git-send-email-tom@tromey.com> (raw)
In-Reply-To: <1476393012-29987-1-git-send-email-tom@tromey.com>
This changes elf_read_minimal_symbols to use gdb::unique_ptr rather
than an explicit allocation. This removes a cleanup.
2016-09-26 Tom Tromey <tom@tromey.com>
* elfread.c (elf_read_minimal_symbols): Use gdb::unique_ptr.
