commit bf79a337ec86c2530edd26f4270f9688bf428ea2
Author: Aurelien Jarno <aurelien@aurel32.net>

sparc32/sparcv9: add a VIS3 version of fdim
sparc32 passes floating point values in the integer registers. VIS3
instructions gives access to the movwtos instruction to directly
transfer a value from an integer register to a floating point register.
Therefore it makes sense to provide a VIS3 version consisting in the
generic version compiled with -mvis3.
Changelog:
* math/s_fdim.c: Avoid alias renamed.
* math/s_fdimf.c: Likewise.
* sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/Makefile
[$(subdir) = math && $(have-as-vis3) = yes] (libm-sysdep_routines):
Add s_fdimf-vis3, s_fdim-vis3.
(CFLAGS-s_fdimf-vis3.c): New. Set to -Wa,-Av9d -mvis3.

commit 8a9f4eb95894eae7e725e79721ba26fbc5b4ed06
Author: Aurelien Jarno <aurelien@aurel32.net>
Date: Fri Aug 5 22:35:01 2016 +0200
sparc: remove fdim sparc specific implementations
The fdim and fdimf functions on sparc do not fully follow the standard
and do not set errno to ERANGE when the result overflows. Since glibc
2.24 this causes the two following tests to fail:
Failure: fdim (max_value, -max_value): errno set to 0, expected 34 (ERANGE)
Failure: fdim_upward (max_value, -max_value): errno set to 0, expected 34 (ERANGE)
It happens that using GCC with the generic C code generates very similar
code to the sparc specific implementations. Therefore this patches
remove them. Note it might still worth adding a vis3 specific version of
fdim on sparc32/sparcv9, this is done in a following patch to ease
backporting.
Changelog:
* sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/Makefile
[$(subdir) = math && $(have-as-vis3) = yes] (libm-sysdep_routines):
Remove s_fdimf-vis3, s_fdim-vis3.

commit 9c8addbc1cd414711310c5a47693f5b0f0b9be3a
Author: Aurelien Jarno <aurelien@aurel32.net>
Date: Fri Aug 5 22:35:01 2016 +0200
sparc: build with -mvis on sparc32/sparcv9 and sparc64
When building for sparc32/sparcv9 or sparc64, we assume that VIS
instructions are available and use them in the sparc specific assembly
code. However we do not tell GCC to use such instructions, resulting in
slightly suboptimal code.
Fix that by passing -Wa,-Av9a -mvis to GCC.
Changelog:
* sysdeps/sparc/sparc32/sparcv9/Makefile (sysdep-CFLAGS): Add -mvis.
* sysdeps/sparc/sparc64/Makefile (sysdep-CFLAGS): New. Define to
-Wa,-Av9a -mvis.
