Reduce code complexity by replacing the floating-point implementation with a 32-bit implementation. Moreover this improves the performance on 386: name old time/op new time/op delta 64-2 972ns ± 2% 350ns ± 1% -64.04% (p=0.029 n=4+4) 1K-2 10.9µs ± 3% 4.2µs ± 1% -61.11% (p=0.029 n=4+4) 64Unaligned-2 969ns ± 2% 354ns ± 2% -63.44% (p=0.029 n=4+4) 1KUnaligned-2 10.8µs ± 3% 4.2µs ± 1% -61.15% (p=0.029 n=4+4) name old speed new speed delta 64-2 65.8MB/s ± 2% 182.9MB/s ± 1% +177.93% (p=0.029 n=4+4) 1K-2 94.3MB/s ± 3% 242.3MB/s ± 1% +157.08% (p=0.029 n=4+4) 64Unaligned-2 66.0MB/s ± 2% 180.4MB/s ± 2% +173.32% (p=0.029 n=4+4) 1KUnaligned-2 94.4MB/s ± 3% 243.0MB/s ± 1% +157.36% (p=0.029 n=4+4) There are already optimized versions for amd64 and arm, and a optimized version for s390x seems to be planned.
