	* s-inmaop-vxworks.adb (Setup_Interrupt_Mask): Do nothing instead of

2011-08-03  Ed Schonberg  <schonberg@adacore.com>

	* sem_res.adb (Set_String_Literal_Subtype): if index type is an integer
	type, always use 1 as the lower bound or string, even if lower bound of
	context is not static, to handle properly null strings in a non-static
	context.

2011-08-03  Bob Duff  <duff@adacore.com>

	* sem_prag.adb (Resolve_Aggregate): An array aggregate with 'others' is
	always legal on the right-hand side of an assignment statement; there
	is always an applicable index constraint in this case. Therefore, the
	check for Pkind = N_Assignment_Statement is now unconditional -- it
	doesn't depend on whether Is_Constrained (Typ).

2011-08-03  Thomas Quinot  <quinot@adacore.com>

	* exp_ch5.adb (Expand_N_Assignment_Statement): Do not force inlining of
	tagged assignment when discriminant checks are suppressed. This is
	useless and extremely costly in terms of static stack usage.

2011-08-03  Bob Duff  <duff@adacore.com>

	* sem_prag.adb (Get_Base_Subprogram): Do not follow Alias for instances
	of generics, because this leads to the wrong entity in the wrong scope,
	causing (e.g.) pragma Export_Procedure to get an error if the entity is
	an instance.
	(Process_Interface_Name): Follow Alias for instances of generics, to
	correct for the above change.

2011-08-03  Ed Schonberg  <schonberg@adacore.com>

	* exp_ch4.adb (Expand_N_Selected_Component): If the discriminant value
	is an integer literal it is always safe to replace the reference. In
	addition, if the reference appears in the generated code for an object
	declaration it is necessary to copy because otherwise the reference
	might be to the uninitilized value of the discriminant of the object
	itself.

	* adaint.c (__gnat_is_executable_file_attr): Fix Win32 circuitry when no
	ACL used, in this case we want to check for ending .exe, not .exe
	anywhere in the path.

	* tree_io.ads (ASIS_Version_Number): Update because of the changes in

	* sem_aggr.adb (Analyze_Array_Aggregate): When checking the discrete

	* exp_ch13.adb (Expand_N_Freeze_Entity): cleanup determination of scope
	in which entity is frozen, to handle properly loop variables in
	iterators.

2011-08-03  Ed Schonberg  <schonberg@adacore.com>

	* sem_res.adb (Set_String_Literal_Subtype): if the lower bound of the
	subtype is not static, compute the upper bound using attributes, to
	handle properly index types that are not integer types.

2011-08-03  Bob Duff  <duff@adacore.com>

	* gnat_rm.texi, gnat_ugn.texi: Fix some dangling URLs.
	Update copyright notice.

	* sem_ch3.adb (Build_Discriminant_Constraints): Only use
	Original_Discriminant if within an instance.
	* sem_ch4.adb (Analyze_Selected_Component): Ditto.

2011-08-03  Ed Schonberg  <schonberg@adacore.com>

	* sem_ch3.adb (Analyze_Object_Declaration): if a constant object of an
	unconstrained type with discriminants is initialized with an aggregate,
	use the constrained subtype of the aggregate as the type of the object,
	because it is immutable, and this allows the back-end to generate no
	code for the object declaration.

2011-08-03  Javier Miranda  <miranda@adacore.com>

	* exp_intr.adb
	(Expand_Dispatching_Constructor_Call): Disable expansion of
	code required for native targets. Done to avoid generating
	references to unavailable runtime entities in VM targets.
	* exp_ch3.adb
	(Expand_N_Object_Declaration): Add missing support to handle
	the explicit initialization of class-wide interface objects.
	Fix documentation.
