    sparc: refactor sparc32 nearbyint{f} selector to C
    
    This patch refactors the sparc32 ifunc selector to a C implementation.
    Also, the generic symbol is moved to its own implementation file
    s_nearbyint{f}-generic.S).
    
    Checked on sparc64-linux-gnu and sparcv9-linux-gnu.
    
    	* sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/Makefile
    	(libm-sysdep_routines): Add s_nearbyintf-generic and
    	s_nearbyint-generic.
    	* sysdeps/sparc/sparcv9/fpu/multiarch/s_nearbyint-generic.S: New
    	file.

    sparc: refactor sparc64 __mpn_add_n selector to C
    
    This patch refactors the sparc64 ifunc selector to a C implementation.
    Also, the generic symbol is moved to its own implementation file
    add_n-generic.S).
    
    Checked on sparc64-linux-gnu and sparcv9-linux-gnu.
    
    	* sysdeps/sparc/sparc64/multiarch/Makefile (sysdep_routines):
    	Add add_n-generic.

    sparc: refactor sparc64 __mpn_sub_n selector to C
    
    This patch refactors the sparc64 ifunc selector to a C implementation.
    Also, the generic symbol is moved to its own implementation file
    sub_n-generic.S).
    
    Checked on sparc64-linux-gnu and sparcv9-linux-gnu.
    
    	* sysdeps/sparc/sparc64/multiarch/Makefile (sysdep_routines):
    	Add sub_n-generic.
    	* sysdeps/sparc/sparc64/multiarch/sub_n-generic.S: New file.
    	* sysdeps/sparc/sparc64/multiarch/sub_n.c: Likewise.
    	* sysdeps/sparc/sparc64/multiarch/sub_n.S: Remove file.

    sparc: refactor sparc64 lrint{f} selector to C
    
    This patch refactors the sparc64 ifunc selector to a C implementation.
    Also, the generic symbol is moved to its own implementation file
    s_lrint{f}-generic.S).
    
    Checked on sparc64-linux-gnu and sparcv9-linux-gnu.
    
    	* sysdeps/sparc/sparc64/fpu/multiarch/Makefile
    	(libm-sysdep_routines): Add s_lrint-generic and s_lrint-generic
    	objects.

commit 8332778f92d81bd3e163517dcfddb1c438cc4f02

    sparc: refactor sparc64 signbit{f} selector to C
    
    This patch refactors the sparc64 ifunc selector to a C implementation.
    Also, the generic symbol is moved to its own implementation file
    (s_signbit-generic.S).
    
    The patch simplifies the Makefile by moving the common objects from
    libm-sysdeps_routines and sysdeps_routines to sysdeps_call rule and
    including it where required with the correct prefix.
    
    Checked on sparc64-linux-gnu and sparcv9-linux-gnu.
    
    	* sysdeps/sparc/sparc-ifunc.h (sparc_libm_ifunc_redirected): New
    	macro.
    	* sysdeps/sparc/sparc64/fpu/multiarch/Makefile (sysdep_calls): New
    	rule.
    	(sysdep_routines): Use sysdep_calls as base.
    	(libm-sysdep_routines): Add generic rule for symbols shared with
    	libc.  Add s_signbit-generic and s_signbitf-generic objects.
    	* sysdeps/sparc/sparc64/fpu/multiarch/s_signbit.c: New file.

    sparc: Assume VIS3 support
    
    This patch assumes VIS3 support by binutils, which is support since
    binutils 2.22.  This leads to soem code simplification, mostly on
    multiarch build where there is no more 2 variant possible (whether
    binutils supports VIS3 instructions or not).
    
    For multiarch files whether HAVE_AS_VIS3_SUPPORT was checked and
    the default implementation was built with a different name, a new
    file with (implementation with -generic appended) is added.
    
    Checked on sparc64-linux-gnu and sparcv9-linux-gnu.

commit 7b5281026d6a00810b9e1157964a01a4f4d09026
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date:   Tue Oct 3 10:58:29 2017 -0300

    sparc: Implement memset/bzero ifunc selection in C
    
    This patch refactor the SPARC64 ifunc selector to a C implementation.
    No functional change is expected, including ifunc resolution rules.
    
    Checked on sparc64-linux-gnu, sparcv9-linux-gnu and x86_64-linux-gnu.
    
    	* sysdeps/sparc/sparc32/sparcv9/multiarch/Makefile
    	[$(subdir) = string] (sysdep_routines): Add memset-ultra1.
    	* sysdeps/sparc/sparc64/multiarch/Makefile [$(subdir) = string]

    	file.

commit 442a66b08b3fd845bfe1f462a949ca17abaeb360
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date:   Tue Oct 3 00:48:27 2017 -0300

    sparc: Implement memcpy/mempcpy ifunc selection in C
    
    This patch refactor the SPARC64 ifunc selector to a C implementation.
    The x86_64 implementation is used as default, which resulted in common
    definitions (ifunc-init.h) used on both architectures.  No functional
    change is expected, including ifunc resolution rules.
    
    Checked on sparc64-linux-gnu, sparcv9-linux-gnu and x86_64-linux-gnu.

    	file.

commit ba3229df7d2903a30f0e831a1e627583974cfa1e
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date:   Fri Oct 6 12:59:32 2017 -0300

    arm: Implement memchr ifunc selection in C
    
    This patch refactor ARM memchr ifunc selector to a C implementation.
    No functional change is expected, including ifunc resolution rules.
    
    It also reorganize the ifunc options code:
    
      1. The memchr_impl.S is renamed to memchr_neon.S and multiple
         compilation options (which route to armv6t2/memchr one) is
         removed.  The code to build if __ARM_NEON__ is defined is
         also simplified.
    
      2. A memchr_noneon is added (which as build along previous ifunc
         resolution) and includes the armv6t2 direct.
    
      3. Same as 2. for loader object.
    
    Alongside the aforementioned changes, it also some cleanus:
    
      - Internal memchr definition (__GI_memcpy) is now a hidden
        symbol.
      - No need to create hidden definition for the ifunc variants.
    
    Checked on armv7-linux-gnueabihf and with a build for arm-linux-gnueabi,
    arm-linux-gnueabihf with and without multiarch support and with both
    GCC 7.1 and GCC mainline.
    
    	* sysdeps/arm/armv7/multiarch/Makefile [$(subdir) = string]
    	(sysdeps_routines): Add memchr_noneon.
    	* sysdeps/arm/armv7/multiarch/ifunc-memchr.h: New file.
    	* sysdeps/arm/armv7/multiarch/memchr_noneon.S: Likewise.

commit 31cacd9d2563031fe3710d7437f4c983b31fc2bb
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>

    arm: Implement memcpy ifunc selection in C
    
    This patch refactor ARM memcpy ifunc selector to a C implementation.
    No functional change is expected, including ifunc resolution rules.
    
    It also adds some cleanup:
    
      - Internal memcpy hidden definition (__GI_memcpy) is now a hidden
        symbol.
    
      - No need to create hidden definition for the ifunc variants.
    
    Checked on armv7-linux-gnueabihf and with a build for arm-linux-gnueabi,
    arm-linux-gnueabihf with and without multiarch support and with both
    GCC 7.1 and GCC mainline.  I also checked with the some possible
    multiarch different configurations that trigger different memcpy
    buids (__ARM_NEON__ && !__SOFT_FP__, !__ARM_NEON__ && !__SOFT_FP__, and
    !__ARM_NEON__ && __SOFT_FP__).
