Vector registers perform better than scalar register pairs for copying data so prefer them instead. This results in a time reduction of over 50% (i.e. 2x speed improvemnet) for some smaller sizes for memcpy-walk. Larger sizes show improvements of around 1% to 2%. memcpy-random shows a very small improvement, in the range of 1-2%. * sysdeps/aarch64/multiarch/memcpy_falkor.S (__memcpy_falkor): Use vector registers. |
