Subject: [PATCH v1 2/6] Benchtests: Add benchtests for __memcmpeq
Date: Tue, 26 Oct 2021 21:43:19 -0500 [thread overview]
Message-ID: <20211027024323.1199441-2-goldstein.w.n@gmail.com> (raw)
In-Reply-To: <20211027024323.1199441-1-goldstein.w.n@gmail.com>
No bug. This commit adds __memcmpeq benchmarks. The benchmarks just
use the existing ones in memcmp. This will be useful for testing
implementations of __memcmpeq that do not just alias memcmp.
