Subject: [PATCH v1 09/23] x86: Remove strcspn-sse2.S and use the generic implementation
Date: Wed, 23 Mar 2022 16:57:26 -0500 [thread overview]
Message-ID: <20220323215734.3927131-9-goldstein.w.n@gmail.com> (raw)
In-Reply-To: <20220323215734.3927131-1-goldstein.w.n@gmail.com>
The generic implementation is faster.
geometric_mean(N=20) of all benchmarks New / Original: .678
All string/memory tests pass.
