Hi Adhemerval, Thanks for commonizing that. I'm surprised it hasn't been done earlier. Anyhow, coincidental timing. I posted https://sourceware.org/ml/libc-alpha/2016-03/msg00642.html friday to optimize strspn with vector bit permutes. We'll need to coordinate these patches. Thanks, Paul

I tested this on POWER7 as well. Although it isn't as good as in POWER8, it's competitive.

I think we should keep them for now.

Do you mean regression on POWER7 only or for POWER8 as well? And what do you mean by 'serious'? I am asking because the algorithm is essentially the same, with the slight difference powerpc64 version does not align neither try to read four bytes at time. I will expect some degradation for strpbrk, since generic call now is calling strcsn.

Both. > And what do you mean by 'serious'? The new strcspn C implementation spent 8x the time of the powerpc64 assembly. While strpbrk spent ~12x the time. Using the benchtests.

I am sending you the benchtests data in attachment. For strcspn if reject is length {0,1} strchrnul will be used, which is way faster than constructing the table and reading byte per byte. Also for the rest of inputs, C version is slight faster in fact. It is the same for strpbrk, since it will call strcspn in the end. The only patch it will be faster is when 'accept == '\0', since powerpc64 algorithm has a fast patch to return 0 in this case (where C implementation will call strchrnul). I am not seeing much difference with default optimization (-O2) as well. strcspn simple_strcspn stupid_strcspn Length 512, alignment 0, rej len 0: 128.422 227.219 455.562 Length 512, alignment 0, rej
