Browse source 
2016-04-20  Richard Biener  <rguenther@suse.de>

	* gimple-match.h (maybe_build_generic_op): Adjust prototype.
	* gimple-match-head.c (maybe_build_generic_op): Pass all ops
	by reference, clear op1 and op2 when GENERICizing BIT_FIELD_REF.
	(maybe_push_res_to_seq): Adjust.
	* gimple-fold.c (maybe_build_generic_op): Likewise.
