*	sparc: refactor sparc64 signbit{f} selector to C	Adhemerval Zanella	2017-11-29	1	-0/+3
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	This patch refactors the sparc64 ifunc selector to a C implementation. Also, the generic symbol is moved to its own implementation file (s_signbit{f}-generic.S). It also simplifies the multiarch Makefile by moving the common objects from libm-sysdeps_routines and sysdeps_routines to a new 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. * sysdeps/sparc/sparc64/fpu/multiarch/s_signbitf.c: Likewise. * sysdeps/sparc/sparc64/fpu/multiarch/s_signbit-generic.S: Likewise. * sysdeps/sparc/sparc64/fpu/multiarch/s_signbitf-generic.S: Likewise. * sysdeps/sparc/sparc64/fpu/multiarch/s_signbit.S: Remove file. * sysdeps/sparc/sparc64/fpu/multiarch/s_signbitf.S: Likewise.

*	sparc: Assume VIS3 support	Adhemerval Zanella	2017-11-29	1	-13/+0
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	This patch assumes VIS3 support by binutils, which is supported since version 2.22. This leads to some code simplification, mostly on multiarch build where there is only one variant instead of previously two (whether binutils supports VIS3 instructions or not). For multiarch files where 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.

*	sparc: Implement memcpy/mempcpy ifunc selection in C	Adhemerval Zanella	2017-11-28	1	-0/+13
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	This patch refactor the SPARC64 ifunc selector to a C implementation.

*	Use generic __ifunc for SPARC.	Joseph Myers	2017-09-26	1	-8/+2
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	glibc fails to build with GCC mainline for SPARC because of the use of manually-created IFUNCs, which fail the tests of compatibility of function alias types. This patch changes sparc-ifunc.h to use the generic __ifunc in defining sparc_libm_ifunc. The generic __ifunc can use the GCC ifunc attribute when available, so ensuring type-correctness as well as better debug info than when setting symbol types in asm statements. Note that for this to fix the build with GCC mainline the GCC patch <https://gcc.gnu.org/ml/gcc-patches/2017-09/msg01779.html>, or building GCC with --enable-gnu-indirect-function, is also needed. Tested (compilation only) with build-many-glibcs.py (sparc64-linux-gnu and sparcv9-linux-gnu, with GCC 8 with the above patch, and also with GCC 7). * sysdeps/sparc/sparc-ifunc.h [!__ASSEMBLER__] (sparc_libm_ifunc): Define using __ifunc.
