commit 2ebfbef8d480d89ba11b9ca8f8adfb4340702a52
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.
    
    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.
    	* sysdeps/arm/armv7/multiarch/rtld-memchr.S: Likewise.
    	* sysdeps/arm/armv7/multiarch/memchr.S: Remove file.
    	* sysdeps/arm/armv7/multiarch/memchr.c: New file.
    	* sysdeps/arm/armv7/multiarch/memchr_impl.S: Move to ...
    	* sysdeps/arm/armv7/multiarch/memchr_neon.S: ... here.

commit 7a205be997c8f08bcf238cd6fbc29d30ac3645e3
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date:   Wed Oct 4 17:44:08 2017 -0300

    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.
    
    To avoid build issues with mainline GCC which set no default gnu
    indirect function support for ARM (--enable-gnu-indirect-function)
    two fixes are added:
    
      1. The new macro arm_libc_ifunc_hidden_def is redefined using
         direct asm assembly directives instead of function attributes.
         This avoid the incompatbile types for a symbol and its alias.
    
      2. A new macro NO_MEM_INTERAL_SYM_HACKS is added on symbol-hacks
         and defined on arm ifunc objects.  It avoids the symbol
         definition loop because compiler might emit the hacks for first
         fix before the ifunc function definition itself.
    
    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.

    Add build-many-glibcs.py arm-linux-gnueabihf-v7{-disable-multiarch}
    
    This patch adds two extra configuration for arm-linux-gnueabihf to
    cover for multiarch support:
    
      1. arm-linux-gnueabihf-v7a: enables multiarch support by using
         -march=armv7a.
    
      2. Same as 1. but with --disable-multiarch.
    
    Check with build-many-glibcs.py for both options.
    
    	* scripts/build-many-glibcs.py (Context.add_all_configs):
    	Add arm-linux-gnueabihf multiarch extra_glibcs.

    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.

commit 9d6c742ffb8d299302442f7ac5f8d79cb60b7fd5
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.

commit 1c64117503c46fc17ea40ba37e0865fc5db51108
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date:   Thu Oct 12 16:24:44 2017 -0300

    Add common ifunc-init.h header
    
    This patch moves the generic definition from x86_64 init-arch
    to a common header ifunc-init.h.  No functional changes is expected.
    
    Checked on a x86_64-linux-gnu build.
    
    	* sysdeps/generic/ifunc-init.h: New file.
    	* sysdeps/x86/init-arch.h: Use generic ifunc-init.h.

commit 58ee535947f5b0a8dad0f2fe7984570ce06db61b
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date:   Tue Oct 10 11:12:50 2017 -0300

    Avoid build multiarch if compiler warns about mismatched alias
    
    GCC 8 emits an warning for alias for functions with incompatible types
    and it is used extensivelly for ifunc resolvers implementations in C
    (for instance on weak_alias with the internal symbol name to the
    external one or with the libc_hidden_def to set ifunc for internal
    usage).
    
    This breaks the build when the ifunc resolver is not defined using
    gcc attribute extensions (HAVE_GCC_IFUNC being 0).  Although for
    all currently architectures that have multiarch support this compiler
    options is enabled for default, there is still the option where the
    user might try build glibc with a compiler without support for such
    extension.  In this case this patch just disable the multiarch folder
    in sysdeps selections.
    
    GCC 7 and before still builds IFUNCs regardless of compiler support
    (although for the lack of attribute support debug information would
    be optimal).
    
    The patch also fixes the default value of the multiarch support in
    configure.ac (the correct value which is tested later in the script
    assumer 'yes' instead of 'default').
    
    Checked with a build on multiarch support architectures (aarch64,a
    arm, sparc, s390, powerpc, x86_64, i386) with multiarch enable
    and disable and with GCC 7 and GCC 8.
