+	* config/rs6000/predicates.md (xxspltidp_operand): Do not special
+	case 0.0.

+	the warning about XXSPLTIDP being undefined here, from the
+	insn generation.
+	* config/rs6000/rs6000-protos.h (rs6000_emit_xxspltidp_v2df):
+	Delete.

+	(xxspltidp<mode>): Use SFDF, not SF_DF_V2DF.
+	* config/rs6000/vsx.md (vsx_splat_<mode>): Don't force constants
+	that can be handled with XXSPLTIDP into registers.
