	* sem_intr.adb (Check_Shift): Use RM_Size instead of Esize, when
	checking that the 'Size is correct. If the type is "mod 2**12",
	for example, it's illegal, but Esize is the 'Object_Size, which
	will be something like 16 or 32, so the error ('Size = 12) was
	not detected.
	* gnat_rm.texi: Improve documentation of shift
	and rotate intrinsics.

	* prj.adb (For_Every_Project_Imported): Fix
	implementation to make sure we return each project only once
	for aggragte libraries. It is fine to return a project twice for
	aggregate projects, this was the case as a Project_Id is different
	in each project tree. The new implementation use a table based on
	the project name to ensure proper detection of duplicate project
	in aggregate library. A new context is then created to continue
	retrurning duplicate project for aggregate libraries.

	* gcc-interface/trans.c (call_to_gnu): Create the temporary for the
	return value in the variable-sized return type case if the target is
	an array with fixed size.  However, do not create it if this is the
	expression of an object declaration.

	* gcc-interface/trans.c (addressable_p) <COMPONENT_REF>: Fix thinko.

2012-01-06  Robert Dewar  <dewar@adacore.com>

	* a-wichha.ads, a-wichun.ads, a-zchhan.ads, a-zchuni.ads,
	s-utf_32.ads: Add pragma Pure
	* s-utf_32.adb: Suppress warnings on non-static constants (now
	that this is Pure).

	Ada_Pass_By_Copy and Ada_Pass_By_Reference.

2012-01-06  Gary Dismukes  <dismukes@adacore.com>

	* a-tienio.adb (Put): Add exception message on
	raise statements. Remove unneeded blocks and object declarations.

2012-01-06  Robert Dewar  <dewar@adacore.com>

	* sem_prag.adb: Minor reformatting.

2012-01-06  Ed Schonberg  <schonberg@adacore.com>

	* sinfo.ads, sinfo.adb (Has_Prefixed_Call): New flag to indicate
	that a selected component within a generic unit has been resolved
	as a prefixed call with local references.
	* sem_ch3.adb (Is_Visible_Component): In an instance body a selected
	component is always visible.
	* sem_ch4.adb (Analyze_Selected_Component): If the node is a
	prefixed call in an instance, do not look for visible components
	of the type.
	* sem_ch12.adb (Reset_Entity): If a selected component has resolved
	to a prefixed call, mark the node accordingly when prefix and
	selector are local references.
