	* aspects.ads Add a comment explaining why SPARK 2014 aspects are
	not delayed. Update the delay status of most SPARK 2014 aspects.
	* sem_ch13.adb (Analyze_Aspect_Specifications): Update all calls
	to Decorate_Aspect_And_Pragma and Insert_Delayed_Pragma to refert
	to Decorate and Insert_Pragma. Add various comments concerning
	the delay status of several SPARK 2014 aspects. The insertion
	of Refined_State now uses routine Insert_After_SPARK_Mode.
	(Decorate): New routine.
	(Decorate_Aspect_And_Pragma): Removed.
	(Insert_Delayed_Pragma): Removed.
	(Insert_Pragma): New routine.

2014-07-30  Ed Schonberg  <schonberg@adacore.com>

	* inline.adb (Expand_Inlined_Call): In GNATprove mode, emit
	only a warning, not an error on an attempt to inline a recursive
	subprogram.
