    	* config/rs6000/rs6000.md (f32_vsx): New mode attributes to
    	refine the constraints used on 32/64-bit floating point moves.

    	(BOOL_REGS_OP2): Likewise.
    	(BOOL_REGS_UNARY): Likewise.
    	(mov<mode>_hardfloat, SFmode/SDmode): Tighten down constraints for
    	32/64-bit floating point moves.  Do not use wa, instead use ww/ws
    	for moves involving VSX registers.  Do not use constraints that
    	target VSX registers for decimal types.
