  This patch removes the powerpc64 optimized strspn, strcspn, and
strpbrk assembly implementation now that the default C one
implements the same strategy.  On internal glibc benchtests
current implementations shows similar performance with -O2.

Tested on powerpc64le (POWER8).

	* sysdeps/powerpc/powerpc64/strcspn.S: Remove file.
	* sysdeps/powerpc/powerpc64/strpbrk.S: Likewise.
	* sysdeps/powerpc/powerpc64/strspn.S: Likewise.

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

Indeed, however a fix is just by adjusting 
sysdeps/powerpc/powerpc64/multiarch/strspn-ppc64.{s,c} like:

---
#include <string.h>

#define STRSPN __strspn_ppc

#undef libc_hidden_builtin_def
#define libc_hidden_builtin_def(name)

extern __typeof (strspn) __strspn_ppc;

#include <string/strspn.c>

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

But the removal of these 2 brings some serious performance degradation.
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.

This is definitively not what I am seeing the environment I am using
(powerpc64le, POWER8E (raw), 3.5GHz, --with-cpu=power7, CFLAGS=-O3,
gcc 4.8.4).
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.
