8536
8537	* exp_util.adb (Is_Iterated_Container): Test
8538	Is_Entity_Name when searching for calls to the default iterator,

8614
86152012-01-10  Bob Duff  <duff@adacore.com>
8616
8617	* sem_intr.adb (Check_Shift): Use RM_Size instead of Esize, when
8618	checking that the 'Size is correct. If the type is "mod 2**12",
8619	for example, it's illegal, but Esize is the 'Object_Size, which
8620	will be something like 16 or 32, so the error ('Size = 12) was
8621	not detected.
8622	* gnat_rm.texi: Improve documentation of shift
8623	and rotate intrinsics.
8624
86252012-01-10  Pascal Obry  <obry@adacore.com>
8626
8627	* prj.adb (For_Every_Project_Imported): Fix
8628	implementation to make sure we return each project only once
8629	for aggragte libraries. It is fine to return a project twice for
8630	aggregate projects, this was the case as a Project_Id is different
8631	in each project tree. The new implementation use a table based on
8632	the project name to ensure proper detection of duplicate project
8633	in aggregate library. A new context is then created to continue
8634	retrurning duplicate project for aggregate libraries.
8635
86362012-01-09  Eric Botcazou  <ebotcazou@adacore.com>
8637
8638	* gcc-interface/trans.c (call_to_gnu): Create the temporary for the
8639	return value in the variable-sized return type case if the target is
8640	an array with fixed size.  However, do not create it if this is the
8641	expression of an object declaration.

8678	component is always visible.
8679	* sem_ch4.adb (Analyze_Selected_Component): If the node is a
8680	prefixed call in an instance, do not look for visible components
8681	of the type.
8682	* sem_ch12.adb (Reset_Entity): If a selected component has resolved
8683	to a prefixed call, mark the node accordingly when prefix and
