Subject: [PATCH v5 2/6] x86: Remove str{n}{case}cmp-ssse3
Date: Thu, 14 Apr 2022 11:47:35 -0500 [thread overview]
Message-ID: <20220414164739.3146735-2-goldstein.w.n@gmail.com> (raw)
In-Reply-To: <20220414164739.3146735-1-goldstein.w.n@gmail.com>
With SSE2, SSE4.1, AVX2, and EVEX versions very few targets prefer
SSSE3. As a result it is no longer worth it to keep the SSSE3
versions given the code size cost.
