743b9c2a98 arm: Remove ununsed ARM code in optimized implementation 
This patch removes the ununsed ARM code path for armv6t2 memchr and
strlen and armv7 memch and strcmp.  In all implementation, the ARM
code is not used in any possible build (unless glibc is explicit
build with the non-documented NO_THUMB compiler flag) and for armv7
the resulting code either produces wrong results (memchr) and throw
build error (strcmp).

Checked on arm-linux-gnueabihf built targeting both armv6 and
armv7.

	* sysdeps/arm/armv6t2/memchr.S (memchr): Remove ARM code path.
	* sysdeps/arm/armv6t2/strlen.S (memchr): Likewise.
	* sysdeps/arm/armv7/multiarch/memchr_neon.S (memchr): Likewise.
	* sysdeps/arm/armv7/strcmp.S (strcmp): Likewise.

81cb7a0b2b Remove sfi_* annotations from ARM assembly files. 
This semi-mechanical patch removes all uses and definitions of the
sfi_breg, sfi_pld, and sfi_sp macros from various ARM-specific
assembly files.  These were only used by NaCl.

	* sysdeps/arm/sysdep.h
        (ARM_SFI_MACROS, sfi_breg, sfi_pld, sfi_sp): Delete definitions.

	* sysdeps/arm/__longjmp.S, sysdeps/arm/add_n.S
	* sysdeps/arm/addmul_1.S, sysdeps/arm/arm-mcount.S
	* sysdeps/arm/armv6/rawmemchr.S, sysdeps/arm/armv6/strchr.S
	* sysdeps/arm/armv6/strcpy.S, sysdeps/arm/armv6/strlen.S
	* sysdeps/arm/armv6/strrchr.S, sysdeps/arm/armv6t2/memchr.S
	* sysdeps/arm/armv6t2/strlen.S
	* sysdeps/arm/armv7/multiarch/memcpy_impl.S
	* sysdeps/arm/armv7/strcmp.S, sysdeps/arm/dl-tlsdesc.S
	* sysdeps/arm/memcpy.S, sysdeps/arm/memmove.S
	* sysdeps/arm/memset.S, sysdeps/arm/setjmp.S
	* sysdeps/arm/strlen.S, sysdeps/arm/submul_1.S:
        Remove all uses of sfi_breg, sfi_pld, and sfi_sp.

f63c86fed0 ARM: Add optimized ARMv7 strcmp implementation 
Add an optimized implementation of strcmp for ARMv7-A cores. This
implementation is significantly faster than the current generic C
implementation, particularly for strings of 16 bytes and longer.

Tested with the glibc string tests for arm-linux-gnueabihf and
armeb-linux-gnueabihf.

The code was written by ARM, who have agreed to assign the copyright
to the FSF for integration into glibc.

ChangeLog:

2014-05-09  Will Newton  <will.newton@linaro.org>

	* sysdeps/arm/armv7/strcmp.S: New file.
	* NEWS: Mention addition of ARMv7 optimized strcmp.
