c8376f3e07 powerpc: strcasecmp/strncasecmp optmization for power8
This implementation utilizes vectors to improve performance
compared to current byte by byte implementation for POWER7.
The performance improvement is upto 4x.  This patch is tested
on powerpc64 and powerpc64le.

A few minor adjustments to the P8 strspn gives us
an almost equally optimized P8 strcspn.

e413b14e18 powerpc: strcasestr optmization for power8
This patch optimizes strcasestr function for power >= 8 systems.  The average
improvement of this optimization is ~40% and compares 16 bytes at a time
using vector instructions.  This patch is tested on powerpc64 and powerpc64le.

25dba0ad05 powerpc: Add optimized P8 strspn
This utilizes vectors and bitmasks.  For small needle, large
haystack, the performance improvement is upto 8x.  For short
strings (0-4B), the cost of computing the bitmask dominates,
and is a tad slower.

502b91de14 powerpc: make memchr use memchr-power7.
In powerpc64, memchr was always pointing to the internal __GI_memchr
implementation.  This patch fixes that and makes it use the
optimized POWER7 version when adequate.

	* sysdeps/powerpc/powerpc64/multiarch/memchr-ppc64.c: Make
	memchr not point to the internal __GI_memchr implementation.

142e0a9953 powerpc: Use default strcpy optimization for POWER7
This patches uses the default strcpy/stpcpy implementation for
POWER7/PPC64.  This is faster in mostly inputs for benchtests

memcpy.

b42f8cad52 powerpc: strstr optimization
This patch optimizes strstr function for power >= 7 systems.  Performance

115e0de72a powerpc: Fix memmove static build
This patch fixes the missing "__memcpy_ppc" symbol for memmove-ppc64
object in static builds.  Since memcpy ifunc is not enabled in static
mode, the specialized symbols are not provided.  The patch changed the
it to just "__memcpy" instead.

10169938b1 powerpc: wordcopy/memmove cleanup for ppc32
This patch cleanup some multiarch code related to memmmove

implementation.  The patch removes the internal IFUNC for wordcopy
symbols and uses local branches in the memmmove optimization instead.

d3b00f468b powerpc: Optimized strncmp for POWER8/PPC64
This patch adds an optimized POWER8 strncmp.  The implementation focus
on speeding up unaligned cases follwing the ideas of power8 strcmp.

The algorithm first check the initial 16 bytes, then align the first
function source and uses unaligned loads on second argument only.
Aditional checks for page boundaries are done for unaligned cases
(where sources alignment are different).

f06a4faf8a powerpc: Optimized st{r,p}ncpy for POWER8/PPC64
This patch adds an optimized POWER8 st{r,p}ncpy using unaligned accesses.
It shows 10%-80% improvement over the optimized POWER7 one that uses
only aligned accesses, specially on unaligned inputs.

The algorithm first read and check 16 bytes (if inputs do not cross a 4K
page size).  The it realign source to 16-bytes and issue a 16 bytes read
and compare loop to speedup null byte checks for large strings.  Also,
different from POWER7 optimization, the null pad is done inline in the
implementation using possible unaligned accesses, instead of realying on
a memset call.  Special case is added for page cross reads.

9f2f36e5a9 powerpc: Optimized strncat for POWER7/PPC64
With 3eb38795db (Simplify strncat) the generic algorithms uses
strlen, strnlen, and memcpy.  This is faster than POWER7 current
implementation, especially for unaligned strings (where POWER7 code
uses byte-byte operations).

This patch removes the assembly implementation and uses a multiarch
specialization based on default algorithm calling optimized POWER7
symbols.

96d6fd6c40 powerpc: Optimized st{r,p}cpy for POWER8/PPC64
This patch adds an optimized POWER8 strcpy using unaligned accesses.
For strings up to 16 bytes the implementation first calculate the
string size, like strlen, and issues a memcpy.  For larger strings,
source is first aligned to 16 bytes and then tested over a loop that
reads 16 bytes am combine the cmpb results for speedup.  Special case is
added for page cross reads.

It shows 30%-60% improvement over the optimized POWER7 one that uses
only aligned accesses.

2cfbdb9a27 Fix strftime wcschr namespace (bug 17634).
Use of strftime, a C90 function, ends up bringing in wcschr, which is
not a C90 function.  Although not a conformance bug (C90 reserves
wcs*), this is still contrary to glibc practice of avoiding relying on
those reservations; this patch arranges for the internal uses to use
__wcschr instead, with wcschr being a weak alias.  This is more
complicated than some such patches because of the various IFUNC
definitions of wcschr (which include code redefining libc_hidden_def
in a way that involves creating __GI_wcschr manually and so also needs
to create __GI___wcschr after the change of internal uses to use
__wcschr).

Tested for x86_64 and 32-bit x86 (testsuite, and that disassembly of
installed shared libraries is unchanged by the patch).

This patch fixes the build of C mempcpy and stpcpy by disabling the

NO_MEMPCPY_STPCPY_REDIRECT is defined, and defining that macro in the
relevant source files.

Tested for powerpc32 that the build is fixed.

71ae86478e PowerPC: memset optimization for POWER8/PPC64
This patch adds an optimized memset implementation for POWER8.  For
sizes from 0 to 255 bytes, a word/doubleword algorithm similar to
POWER7 optimized one is used.

For size higher than 255 two strategies are used:

1. If the constant is different than 0, the memory is written with
   altivec vector instruction;

2. If constant is 0, dbcz instructions are used.  The loop is unrolled
   to clear 512 byte at time.

Using vector instructions increases throughput considerable, with a
double performance for sizes larger than 1024.  The dcbz loops unrolls
also shows performance improvement, by doubling throughput for sizes
larger than 8192 bytes.

17762f6625 PowerPC: optimized memmove for POWER7/PPC64
This patch adds an optimized memmove optimization for POWER7/powerpc64.
Basically the idea is to use the memcpy for POWER7 on non-overlapped
memory regions and a optimized backward memcpy for memory regions
that overlap (similar to the idea of string/memmove.c).

The backward memcpy algorithm used is similar the one use for memcpy for
POWER7, with adjustments done for alignment.  The difference is memory
is always aligned to 16 bytes before using VSX/altivec instructions.
