Liubov Dmitrieva 4b43400f6a optimize the following memcpy: sysdeps/i386/i686/multiarch/memcpy-ssse3.S ... I've improved the following implementation of memcpy: "sysdeps/i386/i686/multiarch/memcpy-ssse3.S". The patch includes some minor style fixes, but the important part is just using prefetch loops for the case: DATA_CACHE_SIZE_HALF <= len < SHARED_CACHE_SIZE_HALF and src and dst pointers have unequal 16 byte alignments. This gives from 6% - 50% performance boost on the atom machine, about 24,73% in geometric mean.		2012-03-30 16:45:27 -04:00
