> 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.

All three patches look great, please commit them and thanks for doing
