Subject: [PATCH v3 2/3] elf: avoid redundant sort in dlopen
Date: Tue, 03 Dec 2019 17:30:00 -0000 [thread overview]
Message-ID: <1575394197-18006-3-git-send-email-david.kilroy@arm.com> (raw)
In-Reply-To: <1575394197-18006-1-git-send-email-david.kilroy@arm.com>
l_initfini is already sorted by dependency in _dl_map_object_deps(),
so avoid sorting again in dl_open_worker().
Tested by running the testsuite on x86_64.
