2012-07-17  Tristan Gingold  <gingold@adacore.com>

	* treepr.adb, treepr.ads: Revert previous patch, unneeded.

2012-07-17  Robert Dewar  <dewar@adacore.com>

	* s-assert.ads: Fix comments to make it clear that this is used
	for all assertions, not just pragma Assert.

2012-07-17  Jerome Guitton  <guitton@adacore.com>

	* par_sco.ads: Minor typo fix.

2012-07-17  Gary Dismukes  <dismukes@adacore.com>

	* layout.adb (Layout_Type): In the case where the target is
	AAMP, use 32 bits (a single pointer) rather than 64 bits for an
	anonymous access-to-subprogram type if the type is library-level
	and Is_Local_Anonymous_Access is True.

2012-07-17  Jose Ruiz  <ruiz@adacore.com>

	* s-tassta.adb, s-tarest.adb (Create_Task, Create_Restricted_Task,
	Initialize): Add comments explaining that the CPU affinity value that
	is passed to the run-time library can be either Unspecified_CPU, to
	indicate that the task inherits the affinity of its activating task,
	or a value in the range of CPU_Range but no greater than Number_Of_CPUs.

	* exp_disp.adb (Make_DT): Remove decoration of Ada.Tags entities.

	* sem_ch6.adb (Check_Statement_Sequence): When locating the
	last significant statement in a sequence, ignore iserted nodes
	that typically come from expansion of controlled operations.
