Improve 64bit memcpy/memmove for Atom, Core 2 and Core i7 This patch includes optimized 64bit memcpy/memmove for Atom, Core 2 and Core i7. It improves memcpy by up to 3X on Atom, up to 4X on Core 2 and up to 1X on Core i7. It also improves memmove by up to 3X on Atom, up to 4X on Core 2 and up to 2X on Core i7. 2010-06-30 15:26:11 +00:00			`strend-sse4 memcmp-sse4 memcpy-ssse3 mempcpy-ssse3 \`
