[multiple changes]

2011-11-04  Yannick Moy  <moy@adacore.com>

	* atree.adb, atree.ads (Set_Original_Node): New set procedure.
	* sem_ch13.adb (Analyze_Aspect_Specifications/Pre_Post_Aspects):
	In ASIS mode, no splitting of aspects between conjuncts.
	(Analyze_Aspect_Specifications/Aspect_Test_Case): Make pragma
	expressions refer to the original aspect expressions through
	the Original_Node link. This is used in semantic analysis for
	ASIS mode, so that the original expression also gets analyzed.
	* sem_prag.adb (Preanalyze_TC_Args,
	Check_Precondition_Postcondition,
	Analyze_Pragma/Pragma_Test_Case): In ASIS mode, for a pragma
	generated from a source aspect, also analyze the original aspect
	expression.
	(Check_Expr_Is_Static_Expression): New procedure
	similar to existing procedure Check_Arg_Is_Static_Expression,
	except called on expression inside pragma.

2011-11-04  Tristan Gingold  <gingold@adacore.com>

	* prj-env.adb, prj-env.ads (Find_Name_In_Path): New function, from
	Find_Project.Try_Path_Name.
	(Find_Project): Use Find_Name_In_Path to implement Try_Path_Name.

2011-11-04  Eric Botcazou  <ebotcazou@adacore.com>

	* s-atocou.ads (Atomic_Counter): Remove redundant pragma Volatile.

2011-11-04  Pascal Obry  <obry@adacore.com>

	* projects.texi: Add short description for qualifiers aggregate
	and aggregate library.

2011-11-04  Matthew Heaney  <heaney@adacore.com>

	* Makefile.rtl, impunit.adb: Added a-cogeso.ad[sb]
	* a-cgaaso.adb: Replaced implementation with instantiation
	of Generic_Sort.
	* a-cogeso.ad[sb] This is the new Ada 2012 unit
	Ada.Containers.Generic_Sort
