2015-05-12  Tristan Gingold  <gingold@adacore.com>

	* i-cpoint.adb (Copy_Terminated_Array): Copy nothing if Length is 0.

2015-05-12  Ed Schonberg  <schonberg@adacore.com>

	* sem_ch3.adb (Complete_Private_Subtype): Propagate
	Has_Delayed_Aspects flag from private to full view, to ensure
	that predicate functions are constructed.

2015-05-12  Ed Schonberg  <schonberg@adacore.com>

	* sem_ch6.adb (Process_Formals): If a tagged formal is an
	incomplete class-wide type, the subprogram must have a delayed
	freeze even though the opertation is not a primitive of the
	type. THis ensures that the backend can recover the full view
	when elaborating the subprogram declaration.

2015-05-12  Ed Schonberg  <schonberg@adacore.com>

	* exp_util.adb (Get_Current_Value_Condition): Nothing to be
	done if an elsif part has been rewritten so that it is not part
	of an enclosing if_statement.
