[thirdparty/gcc.git] / gcc / ada / ChangeLog

2011-08-03  Yannick Moy  <moy@adacore.com>

	* sem_ch11.adb (Analyze_Raise_xxx_Error): do not mark such nodes as not
	in ALFA. Instead, they are considered as assertions to prove.
	* sem_ch4.adb (Analyze_Conditional_Expression): do not always mark such
	nodes as not in ALFA. Instead, include conditional expressions in ALFA
	if they have no ELSE part, or if they occur in pre- and postconditions,
	where the Condition cannot have side-effects in ALFA
	(Analyze_Membership_Op): do not mark such nodes as not in ALFA
	(Analyze_Type_Conversion): do not always mark such nodes as not in ALFA.
	Instead, include type conversion between scalar types in ALFA.

	defining name for the reference to a discriminant.

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

	* sem_disp.adb (Is_Tag_Indeterminate): If the return type of the
	function is not visibly tagged, this is not a dispatching call and

	(Expand_N_Free_Statement): Prevent the generation of a custom
	Deallocate on .NET/JVM targets since this requires pools and address
	arithmetic.
	* exp_ch4.adb (Expand_Allocator_Expression): When compiling for
	.NET/JVM targets, attach the newly allocated object to the access
	type's finalization collection. Do not generate a call to

	exist in the runtime.
	(Expand_N_Allocator): When compiling for .NET/JVM targets, do not
	create a custom Allocate for object that do not require initialization.
	Attach a newly allocated object to the access type's finalization
	collection on .NET/JVM.
	* exp_ch5.adb (Make_Tag_Ctrl_Assignment): Add special processing for

	Prev and Next and stored and later restored after the assignment takes
	place.
	* exp_ch6.adb (Expand_Call): Add local constant Curr_S. Add specialized
	kludge for .NET/JVM to recognize a particular piece of code coming from
	Heap_Management and change the call to Finalize into Deep_Finalize.

	* a-fihema.ads, a-fihema.adb: New GNAT unit.
	Ada.Finalization.Heap_Management provides key functionality
	associated with controlled objects on the heap, their creation,
	finalization and reclamation. Type Finalization_Collection is
	effectively a wrapper which sits ontop of a storage pool and performs
	all necessary bookkeeping for all the objects it contains. Each
	access-to-controlled or access-to-class-wide type receives a collection
	as part of its expansion. The compiler generates buffer code and
	invokes Allocate / Deallocate to create and destroy allocated
	controlled objects.
	* a-finali.adb ("="): Removed.
	* a-finali.ads ("="): Removed. Controlled types no longer carry hidden
	fields Prev and Next.
	* ali.adb (Scan_ALI): Add parsing code to process PF / Has_Finalizer.
	A library unit with at least one controlled object on the library level
	has a special finalizer which is invoked by the binder. To signal this,
	ali files carry field PF.

	associated comment on field usage.
	* a-tags.adb (Get_RC_Offset): Removed.

	Dispatch tables now carry field Needs_Finalization which provides
	runtime indication whether a type is controlled or has controlled
	components or both. Remove field RC_Offset.
	(Get_RC_Offset): Removed along with its associated pragma Export.
	Since tagged types with controlled components no longer carry hidden
	field _controller, the special mechanism to retrieve its location is no
	longer needed.
	(Needs_Finalization): New routine.
	* atree.ads, atree.adb (Elist24): New routine.
	(Set_Elist24): New routine.
	* atree.h: Add a define clause for Elist24.
	* bindgen.adb New library-level variable Lib_Final_Built.
	(Gen_Adafinal_Ada): Reimplemented. Depending on the restrictions or the
	presence of a VM target, the routine generates calls to the proper
	library finalization routine.
	(Gen_Adainit_Ada): Import Finalize_Library_Objects only on non-VM
	targets. Set the correct library finalization routine depending on
	whether the library has controlled objects or this is a VM compilation.
	(Gen_Finalize_Library_Ada): New routine. This procedure generates calls
	to library-level finalizers of compiled units in reverse order of
	elaboration. It also produces exception management code and reraises a
	potential exception after all units have been finalized.
	(Gen_Finalize_Library_C): New routine. This procedure generates calls to
	library-level finalizers of compiled units in reverse order of
	elaboration.
	(Gen_Finalize_Library_Defs_C): New routine. This procedure generates the
	definitions of all library-level finalizers available to the compilation
	(Gen_Main_Ada): Directly call Adafinal which now contails all target
	dependent code.
	(Gen_Main_C): Add new local constant Needs_Library_Finalization. Call
	System.Standard_Library.Adafinal directly. If the library needs
	finalization actions, create the sequence of finalization calls.
	(Gen_Output_File_Ada): Alphabetize local variables and constants.
	Generate a with clause for System.Soft_Links when compiling for a VM.
	Remove the code which imports System.Standard_Library.Adafinal as
	Do_Finalize. Generate the library finalization routine.
	(Gen_Output_File_C): Add new local constant Needs_Library_Finalization.
	If the library needs finalization actions, create all the definitions
	of library- level finalizers.
	(Has_Finalizer): New routine. Determines whether at least one compiled
	unit has a library-level finalizer.
	Add type Qualification_Mode.
	(Set_Unit_Name): Add a formal which controls the replacement of a dot.
	* einfo.adb: New usage of field 15 as Return_Flag.
	Remove Finalization_Chain_Entity from the usages of field 19.

	* 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

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  Robert Dewar  <dewar@adacore.com>

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.

2011-08-03  Pascal Obry  <obry@adacore.com>

	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  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  Robert Dewar  <dewar@adacore.com>

	* exp_ch4.adb (Optimize_Length_Check): Fix bad handling of case where
	comparison operand is variable, and turns out to be zero or negative.

	sem_util.adb, sem_util.ads, sem_res.adb, sem_ch2.adb, sem_ch4.adb,
	sem_ch6.adb, sem_ch11.adb: Add semantic flag In_Pre_Post_Expression to
	indicate that we are in a precondition or postcondition. This is used in
	Mark_Non_ALFA_Subprogram (renaming of Mark_Non_ALFA_Subprogram_Body) to
	decide whether to flag the spec or body of the current subprogram as
	not in ALFA.

2011-08-02  Fabien Chouteau  <chouteau@adacore.com>

	* impunit.adb: Add Ada.Execution_Time.Interrupts in the Ada2012 package

	cases where nonprimitives can be in the list (such as subprograms in
	nested packages).
	* sem_disp.adb (Derives_From): Use correct condition for checking that
	a formal's type is derived from the type of the corresponding formal in
	the parent subprogram (the condition was completely wrong). Add
	checking that was missing for controlling result types being derived
	from the result type of the parent operation.

	Prepend_Element, since this can result in the operation getting the
	wrong slot in the full type's dispatch table if the full type has

	to the proper position in the full type's primitives
	list later in Sem_Disp.Check_Operation_From_Incomplete_Type.

	* sem_ch6.adb (Process_Formals): First, remove test for being in a
	private part when determining whether to add a primitive with a
	parameter of a tagged incomplete type to the Private_Dependents list.
	Such primitives can also occur in the visible part, and should not have
	been excluded from being private dependents.
	* sem_ch7.adb (Uninstall_Declarations): When checking the rule of
	RM05-3.10.1(9.3/2), test that a subprogram in the Private_Dependents
	list of a Taft-amendment incomplete type is a primitive before issuing
	an error that the full type must appear in the same unit. There are
	cases where nonprimitives can be in the list (such as subprograms in
	nested packages).
	* sem_disp.adb (Derives_From): Use correct condition for checking that
	a formal's type is derived from the type of the corresponding formal in
	the parent subprogram (the condition was completely wrong). Add
	checking that was missing for controlling result types being derived
	from the result type of the parent operation.

	the Original_Node.

2011-08-02  Hristian Kirtchev  <kirtchev@adacore.com>

	* exp_ch5.adb (Expand_Iterator_Loop): Code cleanup and refactoring.
	When a container is provided via a function call, generate a renaming

	and the premature finalization of the container.
	* exp_ch7.adb (Is_Container_Cursor): Removed.
	(Wrap_Transient_Declaration): Remove the supression of the finalization
	of the list controller when the declaration denotes a container cursor,
	it is not needed.
