Re: [PATCH] Fix VIS3 assembler check and conditionalize testsuite on VIS3 support.

I think that we should go the i386 way.  This works on i386 because the 
builtins are always available (when you pass the right options) and the 
assembler rejects the unknown instructions.  So in config/sparc/sparc.h:

#ifndef HAVE_AS_FMAF_HPC_VIS3
#define AS_NIAGARA3_FLAG "b"
#undef TARGET_FMAF
#define TARGET_FMAF 0
#undef TARGET_VIS3
#define TARGET_VIS3 0
#else
#define AS_NIAGARA3_FLAG "d"
#endif

we shouldn't force TARGET_FMAF and TARGET_VIS3 to 0.  The configure test would 
only be used to compute default options.
