	* tree-vect-patterns.c (vect_get_external_def_edge): New function,
	split out from...
	(vect_recog_rotate_pattern): ...here.
	(vect_convert_input): Try to insert casts of invariants in the
	preheader.
	* tree-vect-loop-manip.c (vect_loop_versioning): Don't require the
	preheader to be empty.

	* tree-vect-patterns.c (append_pattern_def_seq): Take an optional
	vector type.  If given, install it in the new statement's
	STMT_VINFO_VECTYPE.
	(vect_element_precision): New function.
	(vect_unpromoted_value): New struct.
	(vect_unpromoted_value::vect_unpromoted_value): New function.
	(vect_unpromoted_value::set_op): Likewise.

	(vect_widened_op_tree, vect_convert_input): Likewise.
	(vect_convert_inputs, vect_convert_output): Likewise.
	(vect_recog_dot_prod_pattern): Use vect_look_through_possible_promotion
	to handle the optional cast of the multiplication result and
	vect_widened_op_tree to detect the widened multiplication itself.
	Do not require the input and output of promotion casts to have
	the same sign, but base the signedness of the operation on the
	input rather than the result.  If the pattern includes two
	promotions, check that those promotions have the same sign.
	Do not restrict the MULT_EXPR handling to a double-width result;
	handle quadruple-width results and wider.  Use vect_convert_inputs
	to convert the inputs to the common type.
	(vect_recog_sad_pattern):  Use vect_look_through_possible_promotion
	to handle the optional cast of the ABS result.  Also allow a sign
	change or a sign extension between the ABS and MINUS.
	Use vect_widened_op_tree to detect the widened subtraction and use
	vect_convert_inputs to convert the inputs to the common type.
	(vect_handle_widen_op_by_const): Delete.
	(vect_recog_widen_op_pattern): New function.
	(vect_recog_widen_mult_pattern): Use it.
	(vect_recog_widen_shift_pattern): Likewise.
	(vect_recog_widen_sum_pattern): Use
	vect_look_through_possible_promotion to handle the promoted
	PLUS_EXPR operand.

	* gimple-iterator.c (gsi_for_stmt): Add a new overload that takes
	the containing gimple_seq *.
	* gimple-iterator.h (gsi_for_stmt): Declare it.

	(vect_recog_mask_conversion_pattern): Remove STMT_VINFO_IN_PATTERN_P
	checks.
	(vect_init_pattern_stmt, vect_set_pattern_stmt): New functions,
	split out from...
	(vect_mark_pattern_stmts): ...here.  Handle cases in which the
	statement being replaced is part of an existing pattern
	definition sequence, inserting the new pattern statements before
	the original one.
	(vect_pattern_recog_1): Don't return a bool.  If the statement
	is already part of a pattern, instead apply pattern matching
	to the pattern definition statements.  Don't clear the
	STMT_VINFO_RELATED_STMT if is_pattern_stmt_p.
	(vect_pattern_recog): Don't break after the first match;
	continue processing the pattern definition statements instead.
	Don't bail out for STMT_VINFO_IN_PATTERN_P here.

2018-06-30  Richard Sandiford  <richard.sandiford@arm.com>

	* tree-vect-loop.c (vectorizable_reduction): Assert that the
	phi is not a pattern statement and has not been replaced by
	a pattern statement.
	* tree-vect-patterns.c (type_conversion_p): Don't check
	STMT_VINFO_IN_PATTERN_P.
	(vect_recog_vector_vector_shift_pattern): Likewise.
	(vect_recog_dot_prod_pattern): Expect vect_is_simple_use to return
	the pattern statement rather than the original statement; check
	directly for a WIDEN_MULT_EXPR here.
	* tree-vect-slp.c (vect_get_and_check_slp_defs): Expect
	vect_is_simple_use to return the pattern statement rather
	than the original statement; use is_pattern_stmt_p to check
	for such a pattern statement.
	* tree-vect-stmts.c (process_use): Expect vect_is_simple_use
	to return the pattern statement rather than the original statement;
	don't do the same transformation here.
	(vect_is_simple_use): If the defining statement has been replaced
	by a pattern statement, return the pattern statement instead.
	Remove the corresponding (local) transformation from the vectype
	overload.

	* tree-vectorizer.h (vect_is_simple_use): Move the gimple ** to the
