Re: RFC: modify ppc expanders to support e500


	* config/rs6000/rs6000.md (fix_truncdffsi2): Handle e500
	doubles.
	(floatunssidf2): Same.
	(floatsidf2): Same.
	("extendsfdf2"): New expander.
	(*extendsfdf2_fpr): Rename.
	(*truncdfsf2_fpr): Same.
	(*negdf2_fpr): Same.
	(*absdf2_fpr): Same.
	(*nabsdf2_fpr): Same.
	(*adddf3_fpr): Same.
	(*subdf3_fpr): Same.
	(*muldf3_fpr): Same.

Please properly wrap the overly long final condition for fix_truncdfsi2.
Okay with that change.
