Subject: [PATCH v2 2/3] elf: avoid redundant sort in dlopen
Date: Thu, 24 Oct 2019 10:34:00 -0000	[thread overview]
Message-ID: <a9a6da966401bb51b7763a27eb8d898cc2ad24db.1571755115.git.david.kilroy@arm.com> (raw)
In-Reply-To: <cover.1571755115.git.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.
