2012-12-05  Ed Schonberg  <schonberg@adacore.com>

	* sem_util.adb (Build_Explicit_Dereference): Set properly
	the type of the prefix prior to rewriting, because subsequent
	legality checks examine the original node.

2012-12-05  Hristian Kirtchev  <kirtchev@adacore.com>

	* aspects.adb: Add Contract_Cases to the canonical aspects map.
	* aspects.ads: Add aspect Contract_Cases in the various aspect
	tables.
	* par-prag.adb: The parser does not need to perform special
	actions for pragma Contract_Cases.
	* sem_ch6.adb (Expand_Contract_Cases): New routine.
	(Process_Contract_Cases): Convert pragma Contract_Cases into pre-
	and post- condition checks that verify the runtime state of all
	case guards and their corresponding consequences.
	* sem_ch13.adb (Analyze_Aspect_Specifications): Perform
	various legality checks on aspect Contract_Cases. The aspect is
	transformed into a pragma.
	* sem_prag.adb: Add an entry in table Sig_Flags for pragma
	Contract_Cases.
	(Analyze_Pragma): Perform various legality
	checks on pragma Contract_Cases.  The pragma is associated with
	the contract of the related subprogram.
	(Chain_CTC): Omit pragma
	Contract_Cases because it does not introduce a unique case name
	and does not follow the syntax of Contract_Case and Test_Case.
	* snames.ads-tmpl: Add new name Name_Contract_Cases. Add a
	Pragma_Id for Contract_Cases.

	Attribute_Impl_Def table.

	* gnatchop.adb (Read_File): Avoid storage leak, and in most cases avoid
	an extra copy of the string.
