gcc/
	* tree.h (categorize_ctor_elements): Remove comment.  Fix long line.
	(count_type_elements): Delete.
	(complete_ctor_at_level_p): Declare.
	* expr.c (flexible_array_member_p): New function, split out from...
	(count_type_elements): ...here.  Make static.  Replace allow_flexarr
	parameter with for_ctor_p.  When for_ctor_p is true, return the
	number of elements that should appear in the top-level constructor,
	otherwise return an estimate of the number of scalars.
	(categorize_ctor_elements): Replace p_must_clear with p_complete.
	(categorize_ctor_elements_1): Likewise.  Use complete_ctor_at_level_p.
	(complete_ctor_at_level_p): New function, borrowing union logic
	from old categorize_ctor_elements_1.
	(mostly_zeros_p): Return true if the constructor is not complete.
	(all_zeros_p): Update call to categorize_ctor_elements.
	* gimplify.c (gimplify_init_constructor): Update call to
	categorize_ctor_elements.  Don't call count_type_elements.
	Unconditionally prevent clearing for variable-sized types,
	otherwise rely on categorize_ctor_elements to detect
	incomplete initializers.

gcc/cp/
	* typeck2.c (split_nonconstant_init_1): Pass the initializer directly,
	rather than a pointer to it.  Return true if the whole of the value
	was initialized by the generated statements.  Use
	complete_ctor_at_level_p instead of count_type_elements.
