Commit ID 21df37d7fd4dcc9b4a9c319382cc43685c0259c8
Author Fanael Linithien

Provide vectorized NNUE code for SSE2 and MMX targets This patch allows old x86 CPUs, from AMD K8 (which the x86-64 baseline targets) all the way down to the Pentium MMX, to benefit from NNUE with comparable performance hit versus hand-written eval as on more modern processors. NPS of the bench with NNUE enabled on a Pentium III 1.13 GHz (using the MMX code): master: 38951 this patch: 80586 NPS of the bench with NNUE enabled using baseline x86-64 arch, which is how linux distros are likely to package stockfish, on a modern CPU (using the SSE2 code): master: 882584 this patch: 1203945 closes https://github.com/official-stockfish/Stockfish/pull/2956 No functional change.
