	(Resolve_Equality_Op): Do not apply previous

	predefined primitives associated with timed and conditional
	dispatching calls through synchronized interfaces if we are
	compiling under No_Dispatching_Calls.
	(Build_Init_Procedure):  Use RTE_Available to check if a run-time
	service is available before generating a call.
	(Make_Controlling_Function_Wrappers): New procedure.
	(Expand_N_Full_Type_Declaration): Create a class-wide master for
	access-to-limited-interfaces because they can be used to reference
	tasks that implement such limited interface.
	(Build_Offset_To_Top_Functions): Build the tree corresponding to the
	procedure spec and body of the Offset_To_Top function that is generated
	when the parent of a type with discriminants has secondary dispatch
	tables.
	(Init_Secondary_Tags): Handle the case in which the parent of the type
	containing secondary dispatch tables has discriminants to generate the
	correct arguments to call Set_Offset_To_Top.
	(Build_Record_Init_Proc): Add call to Build_Offset_To_Top_Functions.

	* a-tags.ads, a-tags.adb: (Check_Index): Removed.
	Add Wide_[Wide_]Expanded_Name.
	(Get_Predefined_Prim_Op_Address): New subprogram that provides exactly
	the same functionality of Get_Prim_Op_Address but applied to predefined
	primitive operations because the pointers to the predefined primitives
	are now saved in a separate table.
	(Parent_Size): Modified to get access to the separate table of primitive
	operations or the parent type.
	(Set_Predefined_Prim_Op_Address): New subprogram that provides the same
	functionality of Set_Prim_Op_Address but applied to predefined primitive
	operations.
	(Set_Signature): New subprogram used to store the signature of a DT.
	(Displace): If the Offset_To_Top value is not static then call the
	function generated by the expander to get such value; otherwise use
	the value stored in the table of interfaces.
	(Offset_To_Top): The type of the actual has been changed to Address to
	give the correct support to tagged types with discriminants. In this
	case this value is stored just immediately after the tag field.
	(Set_Offset_To_Top): Two new formals have been added to indicate if the
	offset_to_top value is static and hence pass this value to the run-time
	to store it in the table of interfaces, or else if this value is dynamic
	and then pass to the run-time the address of a function that is
	generated by the expander to provide this value for each object of the
	type.

	* rtsfind.ads (Default_Prin_Op_Count): Removed.
	(Default_Prim_Op_Count): New entity
	(Get_Predefined_Prim_Op_Address): New entity

	* exp_ch4.adb (Expand_Allocator_Expression): Pass Allocator => True to
	Make_Adjust_Call done for a newly-allocated object.

	* exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
	in a subprogram are wrapped in a cleanup block, indicate that the
	subprogram contains an inner block with an exception handler.
	(Make_Adjust_Call): New Boolean formal Allocator indicating whether the
	Adjust call is for a newly-allocated object. In that case we must not
	assume that the finalization list chain pointers are correct (since they
	come from a bit-for-bit copy of the original object's pointers) so if
	the attach level would otherwise be zero (no change), we set it to 4
	instead to cause the pointers to be reset to null.

	* s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
	reset chain pointers to null.

2006-02-13  Ed Schonberg  <schonberg@adacore.com>

	* exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
	string, and the context requires a loop for the assignment (e.g.
	because the left-hand side is packed), generate a unique name for the
	temporary that holds the string, to prevent spurious name clashes.

	* exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
	return unconstrained arrays.
	Update comments.
	(Expand_Call):  An indirect call through an access parameter of a
	protected operation is not a protected call.
	Add circuit to raise CE in Ada 2005 mode following call
	to Raise_Exception.
	(Register_DT_Entry): Do nothing if
	the run-time does not give support to abstract interfaces.
	(Freeze_Subprogram): In case of dispatching operations, do not generate
	code to register the operation in the dispatch table if the source
	is compiled with No_Dispatching_Calls.
	(Register_Predefined_DT_Entry): Generate code that calls the new
	run-time subprogram Set_Predefined_Prim_Op_Address instead of
	Set_Prim_Op_Address.

	* sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
	on array assignments if the right-hand side is a function call that has
	been inlined. Check is performed on the assignment in the block.
	(Process_Bounds): If bounds and range are overloaded, apply preference
	rule for root operations to disambiguate, and diagnose true ambiguity.
	(Analyze_Assignment): Propagate the tag for a class-wide assignment with
	a tag-indeterminate right-hand side even when Expander_Active is True.
	Needed to ensure that dispatching calls to T'Input are allowed and
	get the tag of the target class-wide object.

	* sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
	an inherited primitive operation that already overrides several
	abstract interface primitives. For transitivity, the new entity must
	also override all the abstract interface primitives covered by the
	inherited overriden primitive.
	Emit warning if new entity differs from homograph in same scope only in
	that one has an access parameter and the other one has a parameter of
	a general access type with the same designated type, at the same
	position in the signature.
	(Make_Inequality_Operator): Use source locations of parameters and
	subtype marks from corresponding equality operator when creating the
	tree structure for the implicit declaration of "/=". This does not
	change anything in behaviour except that the decoration of the
	components of the subtree created for "/=" allows ASIS to get the
	string images of the corresponding identifiers.
	(Analyze_Return_Statement): Remove '!' in warning message.
	(Check_Statement_Sequence): Likewise.
	(Analyze_Subprogram_Body): For an access parameter whose designated type
	is an incomplete type imported through a limited_with clause, use the
	type of the corresponding formal in the body.
	(Check_Returns): Implicit return in No_Return procedure now raises
	Program_Error with a compile time warning, instead of beging illegal.
	(Has_Single_Return):  Function returning unconstrained type cannot be
	inlined if expression in unique return statement is not an identifier.
	(Build_Body_To_Inline): It is possible to inline a function call that
	returns an unconstrained type if all return statements in the function
	return the same local variable. Subsidiary procedure Has_Single_Return
	verifies that the body conforms to this restriction.

	* sem_res.adb (Resolve_Equality_Op): If the operands do not have the
	same type, and  one of them is of an anonymous access type, convert
	the other operand to it, so that this is a valid binary operation for
	gigi.
	(Resolve_Type_Conversion): Handle subtypes of protected types and
	task types when accessing to the corresponding record type.
	(Resolve_Allocator): Add '\' in 2-line warning message.
	Remove '!' in warning message.
	(Resolve_Call): Add '\' in 2-line warning message.
	(Valid_Conversion): Likewise.
	(Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
	resulting type may be an access type with an implicit dereference.
	Obtain the proper component from the designated type.
	(Make_Call_Into_Operator): Handle properly a call to predefined equality
	given by an expanded name with prefix Standard, when the operands are
	of an anonymous access type.
	(Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
	Explicit_Dereference and Resolve_Selected_Component, to verify that the
	prefix of the expression is not of an incomplete type. Allows full
	diagnoses of all semantic errors.
	(Resolve_Actuals): If the actual is an allocator whose directly
	designated type is a class-wide interface we build an anonymous
	access type to use it as the type of the allocator. Later, when
	the subprogram call is expanded, if the interface has a secondary
	dispatch table the expander will add a type conversion to force
	the displacement of the pointer.
	(Resolve_Call): If a function that returns an unconstrained type is
	marked Inlined_Always and inlined, the call will be inlined and does
	not require the creation of a transient scope.
	(Check_Direct_Boolean_Op): Removed
	(Resolve_Comparison_Op): Remove call to above
	(Resolve_Equality_Op): Remove call to above
	(Resolve_Logical_Op): Inline above, since this is only call.
	(Valid_Conversion): Handle properly conversions between arrays of
	convertible anonymous access types.

	PR ada/25885

	(Set_Literal_String_Subtype): If the lower bound is not static, wrap
	the literal in an unchecked conversion, because GCC 4.x needs a static
	value for a string bound.

	* exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
	components of the corresponding record, take into account component
	definitions that are access definitions.
	(Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
	procedure is not considered a dispatching call and will be expanded
	properly.

2006-02-13  Javier Miranda  <miranda@adacore.com>

	* exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
	controlling argument of the dispatching call is an abstract interface
	class-wide type then we use it directly.
	Check No_Dispatching_Calls restriction.
	(Default_Prim_Op_Position): Remove the code that looks for the last
	entity in the list of aliased subprograms. This code was wrong in
	case of renamings.
	(Fill_DT_Entry): Add assertion to avoid the use of this subprogram
	when the source is compiled with the No_Dispatching_Calls restriction.
	(Init_Predefined_Interface_Primitives): No need to inherit primitives
	if we are compiling with restriction No_Dispatching_Calls.
	(Make_Disp_XXX): Addition of assertion to avoid the use of all these
	subprograms if we are compiling under No_Dispatching_Calls restriction.
	(Make_DT): Generate a dispatch table with a single dummy entry if
	we are compiling with the No_Dispatching_Calls restriction. In
	addition, in this case we don't generate code that calls to the
	following run-time subprograms: Set_Type_Kind, Inherit_DT.
	(Make_Select_Specific_Data_Table): Add assertion to avoid the use
	of this subprogram if compiling with the No_Dispatching_Calls
	restriction.
	(Expand_Type_Conversion): Instead of using the actual parameter,
	the argument passed as parameter to the conversion function was
	erroneously referenced by the expander.
	(Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
	Set_Predefined_Primitive_Op_Address and Set_Signature.
	(Expand_Dispatching_Call): Generate call to
	Get_Predefined_Prim_Op_Address for predefined primitives.
	(Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
	predefined primitives.
	(Make_DT, Make_Secondary_DT): If the tagged type has no user defined
	primitives we reserve one dummy entry to ensure that the tag does not
	point to some memory that is associated with some other object. In
	addition, remove all the old code that generated the assignments
	associated with the signature of the dispatch table and replace them
	by a call to the new subprogram Set_Signature.
	(Set_All_DT_Position): Change the algorithm because now we have a
	separate dispatch table associated with predefined primitive operations.
	(Expand_Interface_Conversion): In case of non-static offset_to_top
	add explicit dereference to get access to the object after the call
	to displace the pointer to the object.
	(Expand_Interface_Thunk): Modify the generation of the actual used
	in the calls to the run-time function Offset_To_Top to fulfil its
	new interface.
	(Make_DT): Add the new actuals required to call Set_Offset_To_Top.

2006-02-13  Pascal Obry  <obry@adacore.com>

	* expect.c (__gnat_expect_portable_execvp): New implementation. The
	previous implementation was using the C runtime spawnve routine but
	the corresponding wait was using directly the Win32 API. This was
	causing some times a lock when waiting for an event using
	WaitForSingleObject in __gnat_waitpid. This new implementation uses
	the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
	API fixes this problem.

	(Check_Private_Child_Unit): Move test for a nonprivate with clause down

	the old error message in this subprogram was replaced with error
	messages that mirror the errors tested and reported by
	Check_Private_Child_Unit.
	Parameter and variable names improved for readability.
	(Install_Limited_Context_Clauses): Remove test for a withed unit being
	private as the precondition for calling
	Check_Private_Limited_Withed_Unit since that subprogram has been
	revised to test public units as well as private units.

	    Javier Miranda  <miranda@adacore.com>

	* sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
	that Scope_Stack.First = 1.
	Properly handle Ada_Version_Explicit and Ada_Version_Config, which
	were not always properly handled previously.
	(Formal_Entity): Complete rewrite, to handle properly some complex case
	with multiple levels of parametrization by formal packages.
	(Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
	to the corresponding derived type declaration for proper semantics.

	* sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
	(Check_Component): Enforce restriction on components of
	unchecked_unions: a component in a variant cannot contain tasks or
	controlled types.
	(Unchecked_Union): Allow nested variants and multiple discriminants, to
	conform to AI-216.
	Add pragma Ada_2005 (synonym for Ada_05)
	Properly handle Ada_Version_Explicit and Ada_Version_Config, which
	were not always properly handled previously.
	Document that pragma Propagate_Exceptions has no effect
	(Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
	(Set_Convention_From_Pragma): Check that if a convention is
	specified for a dispatching operation, then it must be
	consistent with the existing convention for the operation.
	(CPP_Class): Because of the C++ ABI compatibility, the programmer is no
	longer required to specify an vtable-ptr component in the record. For
	compatibility reasons we leave the support for the previous definition.
	(Analyze_Pragma, case No_Return): Allow multiple arguments

	* sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
	non-overrideen inherited operation with a controlling result as
	illegal only its implicit declaration comes from the derived type
	declaration of its result's type.
	(Check_Possible_Deferred_Completion): Relocate the object definition
	node of the subtype indication of a deferred constant completion rather
	than directly analyzing it. The analysis of the generated subtype will
	correctly decorate the GNAT tree.
	(Record_Type_Declaration): Check whether this is a declaration for a
	limited derived record before analyzing components.
	(Analyze_Component_Declaration): Diagnose record types  not explicitly
	declared limited when a component has a limited type.
	(Build_Derived_Record_Type): Code reorganization to check if some of
	the inherited subprograms of a tagged type cover interface primitives.
	This check was missing in case of a full-type associated with a private
	type declaration.
	(Constant_Redeclaration): Check that the subtypes of the partial and the
	full view of a constrained deferred constant statically match.
	(Mentions_T): A reference to the current type in an anonymous access
	component declaration  must be an entity name.
	(Make_Incomplete_Type_Declaration): If type is tagged, set type of
	class_wide type to refer to full type, not to the incomplete one.
	(Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
	available. Required to give support to the certified run-time.
	(Analyze_Component_Declaration): In case of anonymous access components
	perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
	(Process_Discriminants): For an access discriminant, use the
	discriminant specification as the associated_node_for_itype, to
	simplify accessibility checks.

2006-02-13  Ed Schonberg  <schonberg@adacore.com>
	    Javier Miranda  <miranda@adacore.com>

	* sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
	abstract interpretations on an operator, remove interpretations that
	yield Address or a type derived from it, if one of the operands is an
	integer literal.
	(Try_Object_Operation.Try_Primitive_Operation,
	Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
	location when creating the new reference to a primitive or class-wide
	operation as a part of rewriting a subprogram call.
	(Try_Primitive_Operations): If context requires a function, collect all
	interpretations after the first match, because there may be primitive
	operations of the same type with the same profile and different return
	types. From code reading.
	(Try_Primitive_Operation): Use the node kind to choose the proper
	operation when a function and a procedure have the same parameter
	profile.
	(Complete_Object_Operation): If formal is an access parameter and prefix
	is an object, rewrite as an Access reference, to match signature of
	primitive operation.
	(Find_Equality_Type, Find_One_Interp): Handle properly equality given
	by an expanded name with prefix Standard, when the operands are of an
	anonymous access type.
	(Remove_Abstract_Operations): If the operation is abstract because it is
	inherited by a user-defined type derived from Address, remove it as
	well from the set of candidate interpretations of an overloaded node.
	(Analyze_Membership_Op): Membership test not applicable to cpp-class
	types.

2006-02-13  Bob Duff  <duff@adacore.com>

	* sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
	redundant use clauses.
	In particular, if the scope of two use clauses overlaps, but one is not
	entirely included in the other, we should not warn.  This can happen
	with nested packages.
	(Analyze_Subprogram_Renaming): Protect the compiler against previously
	reported errors. The bug was reported when the compiler was built
	with assertions enabled.
	(Find_Type): If the node is a 'Class reference and the prefix is a
	synchronized type without a corresponding record, return the type
	itself.

2006-02-13  Javier Miranda  <miranda@adacore.com>

	* sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
	if this is the full-declaration associated with a private declaration
	that implement interfaces, then the private type declaration must be
	limited.
	(Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
	as aliased. The use of the 'access attribute is not available for such
	object (for this purpose the object should be explicitly marked as
	aliased, but being an anonymous type this is not possible).

2006-02-13  Ed Schonberg  <schonberg@adacore.com>
	    Robert Dewar  <dewar@adacore.com>

	* sem_elab.adb (Same_Elaboration_Scope): A package that is a
	compilation unit is an elaboration scope.
	(Add_Task_Proc): Add '\' in 2-line warning message.
	(Activate_All_Desirable): Deal with case of unit with'ed by parent

2006-02-13  Ed Schonberg  <schonberg@adacore.com>
	    Javier Miranda  <miranda@adacore.com>

	* sem_type.adb (Write_Overloads): Improve display of candidate
	interpretations.
	(Add_One_Interp): Do not add to the list of interpretations aliased
	entities corresponding with an abstract interface type that is an
	immediate ancestor of a tagged type; otherwise we have a dummy
	conflict between this entity and the aliased entity.
	(Disambiguate): The predefined equality on universal_access is not
	usable if there is a user-defined equality with the proper signature,
	declared in the same declarative part as the designated type.
	(Find_Unique_Type): The universal_access equality operator defined under
	AI-230 does not cover pool specific access types.
	(Covers): If one of the types is a generic actual subtype, check whether
	it matches the partial view of the other type.

2006-02-13  Thomas Quinot  <quinot@adacore.com>

	* sinput-d.adb (Write_Line): Update the Source_Index_Table after each
	line. This is necessary to allow In_Extended_Main_Unit to provide
	correct results for itypes while writing out expanded source.
	(Close_File): No need to update the source_index_table here since it's
	now done for each line.

2006-02-13  Bob Duff  <duff@adacore.com>

	* s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
	Scan_Unsigned, so we do not scan leading blanks and sign twice.
	Integer'Value("- 5") and Integer'Value("-+5") now correctly
	raise Constraint_Error.

	* s-vallli.adb (Scan_Long_Long_Integer): Call
	Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
	do not scan leading blanks and sign twice.
	Integer'Value("- 5") and Integer'Value("-+5") now correctly
	raise Constraint_Error.

	* s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
	Scan_Long_Long_Unsigned): Split out most of the processing from
	Scan_Long_Long_Unsigned out into
	Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
	This prevents scanning leading blanks and sign twice.
	Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
	See RM-3.5(44).

	* s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
	out most of the processing from Scan_Unsigned out into
	Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
	This prevents scanning leading blanks and sign twice.

	* s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
	use with Modular'Value attribute.
	(Scan_Plus_Sign): Add Scan_Plus_Sign, for use with Modular'Value

        * a-taster.ads, a-taster.adb: New files.

	* a-elchha.adb (Last_Chance_Handler): Change the task termination soft

	handler because of an unhandled exception.

	* a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from

	finalization of the global list instead of Adafinal.

	* s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
	non-tasking version of the soft link for task termination. We do
	nothing since if we are using the non-tasking version it
	means that the task termination functionality is not used.
	(Null_Finalize_Global_List): Add this null version for the procedure
	in charge of finalizing the global list for controlled objects.
	(Null_Adafinal): Remove this procedure. Adafinal_NT has been created

	global list for controlled objects if needed, but no tasking
	finalization.

	* s-tarest.adb (Task_Lock): Do not try to lock again the

	some run-time operations.
	(Task_Unlock): Do not try to actually unlock the Global_Task_Lock

	Ada.Task_Termination, for avoiding circular dependencies.
	(Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
	for storing task termination handlers. In addition,
	Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
	Common_ATCB because it is used by both the regular and the restricted
	run times.
	(Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
	Common_ATCB because it is used by both the regular and the restricted
	run times.

	* s-tassta.adb (Abort_Tasks): Move the code in charge of checking
	potentially blocking operations to System.Tasking.Utilities.Abort_Tasks.

	(Task_Wrapper): added dynamic stack analysis.

	* s-tasuti.adb (Abort_Tasks): The code in charge of checking
	potentially blocking operations has been moved from
	System.Tasking.Stages.Abort_Tasks to this procedure. There can be
	direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
	through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
	this run-time check.

	* s-solita.adb (Task_Termination_Handler_T): Add this task-safe version
	of task termination procedure.
	(Init_Tasking_Soft_Links): Install the task-safe version of the soft

	conversion.
	(Get_Tagged_Kind, Set_Tagged_Kind): New bodies.

	* exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
	in all the calls to Expand_Interface_Thunk. Instead of referencing the
	record component containing the tag of the secondary dispatch table we

	PR ada/18434

	* types.ads: Include All_Checks in Suppress_Array

	* checks.adb (Check_Needed): Remove kludge for a/=b rewritten as
	not(a=b), since we no longer do this rewriting, and hence it is not
	needed.
	(Elaboration_Checks_Suppressed): Add special casing to
	deal with different cases of static and dynamic elaboration checks (all
	checks does not count in the first case, but does in the second).
	(Expr_Known_Valid): Do not assume that the result of any arbitrary

	(Ensure_Valid): Do not apply validity check to a real literal
	in a universal or fixed context

	* exp_ch4.adb (Expand_N_Op_Ne): Don't expand a/=b to not(a=b) for
	elementary types using the operator in standard. It is cleaner not to
	modify the programmers intent, especially in the case of floating-point.
	(Rewrite_Comparison): Fix handling of /= (this was always wrong, but
	it did not matter because we always rewrote a/=b to not(a=b).
	(Expand_Allocator_Expression): For an allocator expression whose nominal
	subtype is an unconstrained packed type, convert the expression to its
	actual constrained subtype.
	Implement warning for <= or >= where < or > not possible
	Fix to Vax_Float tests (too early in many routines, causing premature
	Vax_Float expansions.

	to be used with packages and generic packages as well as with
	subprograms.
	(Suppress): Set All_Checks, but not Elaboration_Check, for case

	Allow optional = after -gnatm
	(Scan_Front_End_Switches): The -gnatp switch sets All_Checks, but no
	longer sets Elaboration_Checks.

	statement.

	* s-taprop-solaris.adb:

	if there is an actual subtype provided by the front-end, use that
	subtype to build an actual type with bounds template.

	is provided by the front-end, use that subtype to compute the size of
	the deallocated object.

	check for a potential violation of a No_Elaboration_Code restriction.
	(maybe_stabilize_reference): New function, like gnat_stabilize_reference
	with extra arguments to control whether to recurse through non-values

	from a fat or thin pointer type and a constrained object type.
	(build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
	types variants, and process special cases of VIEW_CONVERT expressions
	as their NOP_EXPR counterpart to ensure we get to the
	CORRESPONDING_VARs associated with CONST_DECls.
	(build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
	on the right-hand side.

	a common pattern.
	(convert) <VIEW_CONVERT_EXPR>: Return the inner operand directly if we
	are converting back to its original type.
	(convert) <JM input>: Fallthrough regular conversion code instead of
	extracting the object if converting to a type variant.

	generation and we are at the top level, check for a potential violation
	of a No_Elaboration_Code restriction.

	SIZE and SIZE_UNIT which we need for later back-annotations.
	* utils.c: (convert) <STRING_CST>: Remove obsolete code.

	'Class reference, it is tagged, and its list of primitive operations
	must be initialized properly.
	(Chain_Use_Clauses): When chaining the use clauses that appear in the

	* exp_ch6.adb (Expand_Call): If an actual is a function call rewritten
	from object notation, the original node is unanalyzed and carries no

	position between 1 and the minimum length of the keys in order to
	avoid reducing one of the keys to an empty string.
	(Initialize, Compute): When the ratio V to K is too low, the algorithm
	does not converge. The initialization procedure now comes with a
	maximum number of iterations such that when exceeded, an exception is

	* sem_attr.adb (Resolve_Attribute, case 'Address): For an illegal
	'Address attribute reference with an overloaded prefix, use the
	location of the prefix (not the location of the attribute reference) as
	the error location.
	(Analyze_Attribute, case 'Size): The name of an enumeration literal, or
	a function renaming thereof, is a valid prefix for 'Size (where it is
	intepreted as a function call).
	(Statically_Denotes_Entity): New predicate to determine whether the

	* sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
	become local to the whole package.
	(Install_Limited_Withed_Unit): Instead of unchaining real entities if
	the package was already analyzed the new algorithm "replaces" the
	real entities by the shadow ones. This is required to ensure that
	the order of these entities in the homonym chains does not change;
	otherwise we can have undefined references at linking time because
	in case of conflicts the external name of the entities will have
	a suffix that depends on the order of the entities in the chain.
	(Remove_Limited_With_Clause): Complementary code that completes the
	new algorithm and replaces the shadow entities by the real ones.
	(Install_Limited_Withed_Unit): When unchaining entities before the
	installation of the shadow entities, only regular entities of the
	public part must be taken into account. This is required to
	keep this routine in synch with the work done by Remove_Limited_
	With_Clause
	(Install_Limited_With_Clause): Introduce implicit limited_with_clause
	even if unit is analyzed, because the analysis of the unit is
	idempotent in any case, and the limited view of the unit may have to
	be installed for proper visibility.
	(Expand_Limited_With_Clause): Even if the unit in the implicit
	with_clause has been analyzed already, a limited view of the package
	must be built for the current context, if it does not exist yet.

	    Javier Miranda  <miranda@adacore.com>
	    Gary Dismukes  <dismukes@adacore.com>

	* sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
	defining entity for the instance body, make a new defining identifier
	rather than copying the entity of the spec, to prevent accidental
	sharing of the entity list.
	(Check_Private_View): When exchanging views of private types, build the
	list of exchanged views as a stack, to ensure that on exit the exchanges
	are undone in the proper order.
	(Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
	Restore the compilation environment in case of instantiation_error.
	(Analyze_Generic_Subprogram_Declaration): Handle creation of type entity

	denotes a generic package renaming.

2005-09-01  Thomas Quinot  <quinot@adacore.com>

	* sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the

	    Gary Dismukes  <dismukes@adacore.com>
	    Ed Schonberg  <schonberg@adacore.com>
	    Javier Miranda  <miranda@adacore.com>

	* sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
	underlying type
	to check if a type is Constrained in cases related to code generation
	(rather than semantic checking) since otherwise we do not generate
	similar code for mutable private types depending if their
	discriminants are visible or not.
	(Check_Abstract_Overriding): Do not complain about failure to override
	the primitive operations used in dispatching selects since they will
	always be overriden at the freeze point of the type.
	(Access_Definition): Separate out handling for resetting the scope
	of an anonymous access function result type. Retrieve the scope
	of the associated function rather than using Current_Scope, which
	does not have a consistent value (depends on whether we're in the
	middle of analyzing formal parameters). Add ??? comment about
	finding a cleaner way to handle the special cases of scope setting.
	(Process_Incomplete_Dependents): A protected operation is never a
	dispatching operation (only its wrapper may be).
	(Build_Derived_Record_Type): In case of tagged private types that
	implement interfaces add derivation of predefined primitive
	operations.
	(Derive_Subprograms): Replace the Is_Interface_Derivation parameter
	by two parameters that are used in case of derivation from abstract
	interface types: No_Predefined_Prims is used to avoid the derivation
	of predefined primitives from the interface, and Predefined
	Prims_Only is used to complete the derivation predefined primitives
	in case of private tagged types implementing interfaces.
	Fix typo in comments
	(Find_Interface_In_Descendant): Protect the frontend against
	wrong code with large circularity chains.
	(Is_Private_Overriding): Add support for entities overriding interface
	subprograms. The test failed because Entities associated with overriden
	interface subprograms are always marked as hidden (and used to build
	the secondary dispatch table); in this case the overriden entity is
	available through the field abstract_interface_alias (cf. override_
	dispatching_operation)
	(Access_Definition): Set the scope of the type to Current_Scope for the
	case of a function with an anonymous access result type.
	(Access_Subprogram_Declaration): Handle creation of the type entity for
	an access-to-function type with an anonymous access result.
	(Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
	in handling for N_Access_Function_Definition.
	(Analyze_Subtype_Declaration): Modify the text of error message.
	(Derived_Type_Declaration): Modify the text of error message.
	(Process_Subtype): Modify the text of error message plus cleanup
	of one redundant error message.
	(Analyze_Component_Declaration): Code cleanup.
	(Analyze_Object_Declaration): Code cleanup.
	(Analyze_Subtype_Declaration): Propagate the null-exclusion
	attribute in case of access types. Code cleanup.
	(Array_Type_Declaration): Code cleanup.
	(Process_Discriminants): Create the new null-excluding itype
	if required. Code cleanup.
	(Process_Subtype): Create the new null-excluding itype if
	required. Code cleanup.
	(Build_Derived_Record_Type): Code cleanup to avoid calling
	twice the subprogram derive_subprograms in case of private
	types that implement interfaces. In this particular case the
	subprogram Complete_Subprograms_Derivation already does the
	job associated with the second call.

        * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
        conversion to the full view when generating an operation for a
        discriminant whose type may currently be private.

2005-09-01  Ed Schonberg  <schonberg@adacore.com>
	    Javier Miranda  <miranda@adacore.com>

	* sem_ch4.adb (Transform_Object_Operation): In a context off the form
	V (Obj.F), the rewriting does not involve the indexed component, but
	only the selected component itself.
	Do not apply the transformation if the analyzed node is an actual of a
	call to another subprogram.
	(Complete_Object_Operation): Retain the entity of the
	dispatching operation in the selector of the rewritten node. The
	entity will be used in the expansion of dispatching selects.
	(Analyze_One_Call): Improve location of the error message associated
	with interface.
	(Analyze_Selected_Component): No need to resolve prefix when it is a
	function call, resolution is done when parent node is resolved, as
	usual.
	(Analyze_One_Call): Add a flag to suppress analysis of the first actual,
	when attempting to resolve a call transformed from its object notation.
	(Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
	of the argument list for each interpretation of the operation.
	(Try_Object_Operation): The designated type of an access parameter may
	be an incomplete type obtained through a limited_with clause, in which
	case the primitive operations of the type are retrieved from its full
	view.
	(Analyze_Call): If this is an indirect call, and the return type of the
	access_to_subprogram is incomplete, use its full view if available.

2005-09-01  Javier Miranda  <miranda@adacore.com>
	    Gary Dismukes  <dismukes@adacore.com>

	* sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
	access types the null-exclusion and access-to-constant attributes must
	also match.
	(Analyze_Return_Statement): When the result type is an anonymous access
	type, apply a conversion of the return expression to the access type
	to ensure that appropriate accessibility checks are performed.
	(Analyze_Return_Type): For the case of an anonymous access result type,
	generate the Itype and set Is_Local_Anonymous_Access on the type.
	Add ??? placeholder for check to disallow returning a limited object
	in Ada 2005 unless it's an aggregate or a result of a function call.
	Change calls from Subtype_Mark to Result_Definition.
	(Analyze_Subprogram_Body): Change formal Subtype_Mark to
	Result_Definition in call to Make_Function_Specification.
	(Build_Body_To_Inline): Change Set_Subtype_Mark to
	Set_Result_Definition.
	(Make_Inequality_Operator): Change formal Subtype_Mark to
	Result_Definition in call to Make_Function_Specification.
	(Process_Formals): Create the new null-excluding itype if required.
	(New_Overloaded_Entity): For an entity overriding an interface primitive
	check if the entity also covers other abstract subprograms in the same
	scope. This is required to handle the general case, that is, overriding
	other interface primitives and overriding abstract subprograms inherited
	from some abstract ancestor type.
	(New_Overloaded_Entity): For an overriding entity that comes from
	source, note the operation that it overrides.
	(Check_Conformance, Type_Conformant): Addition of one new formal
	to skip controlling formals in the analysis. This is used to
	handle overloading of abstract interfaces.
	(Base_Types_Match): Add missing case for types imported from
	limited-with clauses
	(New_Overloaded_Entity): Add barrier to protect the use of
	the "alias" attribute.

2005-09-01  Ed Schonberg  <schonberg@adacore.com>

	* sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
	verify that the procedure and the entry are mode conformant.
	(Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
	as a different operator, which is often a cut-and-paste error.

2005-09-01  Javier Miranda  <miranda@adacore.com>
	    Ed Schonberg  <schonberg@adacore.com>

	* sem_disp.adb (Check_Controlling_Formals): Anonymous access types
	used in controlling parameters exclude null because it is necessary to
	read the tag to dispatch, and null has no tag.
	(Override_Dispatching_Operation): If the previous operation is inherited
	from an interface, it becomes hidden  and does not participate in later
	name resolution.

	* sem_res.adb (Resolve_Membership_Op): In case of the membership test
	"Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
	the expander will generate the corresponding run-time check to evaluate
	the expression.
	(Resolve_Call): Check for legal type of procedure name or prefix that
	appears as a trigger in a triggering alternative.
	(Valid_Conversion): If expression is ambiguous and the context involves
	an extension of System, remove System.Address interpretations.
	(Resolve_Qualified_Expression): Reject the case of a specific-type
	qualification applied to a class-wide argument. Enhance comment
	to explain checking of Original_Node.
	(Resolve_Type_Conversion): The location of the error message was not
	general enough to handle the general case and hence it has been removed.
	In addition, this patch improves the text of the message.
	(Resolve_Type_Conversion): Add missing support for access to interface
	types.
	(Resolve_Type_Conversion): If the target is a class-wide interface type,
	do not expand if the expression is the actual in a call, because proper
	expansion will take place when the call itself is expanded.
	(Resolve_Allocator): If the context is an unchecked conversion, the
	allocator inherits its storage pool, if any, from the target type of
	the conversion.

	    Javier Miranda  <miranda@adacore.com>

	* sem_type.adb (Add_One_Interp): If a candidate operation is an
	inherited interface operation that has an implementation, use the
	implementation to avoid spurious ambiguities.
	(Interface_Present_In_Ancestor): In case of concurrent types we can't
	use the Corresponding_Record_Typ attribute to look for the interface
	because it is set by the expander (and hence it is not always
	available). For this reason we traverse the list of interfaces

	(Add_C_Plus_Plus_Link_For_Gnatmake): Always link with the C++ compiler
	(Choose_C_Plus_Plus_Link_Process): Do not generate shell script
	c++linker as this does not work on some platforms.

	that target.

	* tracebak.c: Remove the mips-irix section, as we are now using the
	s-mastop based unwinder again.
	Under SPARC/Solaris, take into account the stack bias to compute the
	frame offset.  The stack bias is 0 for the V8 ABI and 2047 for the V9
	ABI.

	    Arnaud Charlet  <charlet@adacore.com>

	* a-sytaco.ads, a-sytaco.adb (Suspension_Object): These objects are no
	longer protected objects. They have been replaced by lower-level
	suspension objects made up by a mutex and a condition variable (or
	their equivalent given a particular OS) plus some internal data to
	reflect the state of the suspension object.
	(Initialize, Finalize): Add this initialization procedure for
	Suspension_Object, which is a controlled type.
	(Finalize): Add the finalization procedure for Suspension_Object,
	which is a controlled type.

	* a-sytaco-vxworks.ads, a-sytaco-vxworks.adb: Remove this version of
	Ada.Synchronous_Task_Control because there is no longer a need for a
	VxWorks specific version of this package. Target dependencies
	has been moved to System.Task_Primitives.Operations.

	* s-osinte-mingw.ads (pCRITICAL_SECTION): Remove this type which is no
	longer needed.
	(InitializeCriticalSection, EnterCriticalSection,
	LeaveCriticalSection, DeleteCriticalSection): Replace the type
	pCriticalSection by an anonymous access type so that we avoid problems
	of accessibility to local objects.

	* s-taprop.ads, s-taprop-posix.adb, s-taprop-vxworks.adb,
	s-taprop-mingw.adb, s-taprop-vms.adb, s-taprop-solaris.adb,
	s-taprop-os2.adb, s-taprop-dummy.adb, s-taprop-hpux-dce.adb,
	s-taprop-linux.adb, s-taprop-irix.adb, s-taprop-irix-athread.adb,
	s-taprop-tru64.adb, s-taprop-lynxos.adb (Elaboration Code): No longer
	set the environment task mask here.
	(Current_State): Add this function that returns the state of the
	suspension object.
	(Set_False): Add this procedure that sets the state of the suspension
	object to False.
	(Set_True): Add this procedure that sets the state of the suspension
	object to True, releasing the task that was suspended, if any.
	(Suspend_Until_True): Add this procedure that blocks the calling task
	until the state of the object is True. Program_Error is raised if
	another task is already waiting on that suspension object.
	(Initialize): Add this procedure for initializing the suspension
	object. It initializes the mutex and the condition variable which are
	used for synchronization and queuing, and it sets the internal state
	to False.
	(Finalize): Add this procedure for finalizing the suspension object,
	destroying the mutex and the condition variable.

	* s-taspri-posix.ads, s-taspri-vxworks.ads, s-taspri-mingw.ads,
	s-taspri-vms.ads, s-taspri-solaris.ads, s-taspri-os2.ads,
	s-taspri-dummy.ads, s-taspri-hpux-dce.ads, s-taspri-linux.ads,
	s-taspri-tru64.ads, s-taspri-lynxos.ads (Suspension_Object): New object
	which provides a low-level abstraction (using operating system
	primitives) for Ada.Synchronous_Task_Control.
	This object is made up by a mutex (for ensuring mutual exclusion), a
	condition variable (for queuing threads until the condition is
	signaled), a Boolean (State) indicating whether the object is open,
	and a Boolean (Waiting) reflecting whether there is a task already
	suspended on this object.

	* s-intman.ads, s-intman-irix.adb, s-intman-irix-athread.adb,
	s-intman-dummy.adb, s-intman-solaris.adb, s-intman-vms.adb,
	s-intman-vms.ads, s-intman-mingw.adb,
	(Initialize_Interrupts): Removed, no longer used.

	* s-inmaop-posix.adb, s-inmaop-vms.adb, s-inmaop-dummy.adb,
	(Setup_Interrupt_Mask): New procedure.

	* s-intman-vxworks.ads, s-intman-vxworks.adb:  Update comments.

	* s-inmaop.ads (Setup_Interrupt_Mask): New procedure

	* s-interr.adb: Add explicit call to Setup_Interrupt_Mask now that
	this is no longer done in the body of s-taprop
	(Server_Task): Explicitely test for Pending_Action in case
	System.Parameters.No_Abort is True.

	* s-taasde.adb: Add explicit call to Setup_Interrupt_Mask now that this
	is no longer done in the body of s-taprop

	* sem_ch6.adb, sem_ch9.adb (Analyze_Subprograms_Declaration): Update
	error message condition, null procedures are correctly detected now.
	(New_Overloaded_Entity): Bypass trivial overriding indicator check

	Must_Override and Must_Not_Override, to better express intent of AI.

	such discriminants have their accessibility level defined in the same
	way as a normal component of an anonymous access type.
	(Resolve_Allocator): When an allocator's designated type is a class-wide

	constant-folded, there is nothing to check.
	(Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer
	check on possible violation of restriction No_Direct_Boolean_Operators

	types.

	both bound checks, rather than a conjunction.
	(Insert_Valid_Check): If the expression is an actual that is an indexed
	component of a bit-packed array, force expansion of the packed element
	reference, because it is specifically inhibited elsewhere.

	Add support for Elist16 field
	Add support for Elist24 field

	* einfo.ads, einfo.adb (Abstract_Interfaces,
	Set_Abstract_Interfaces): New subprograms.
	(Abstract_Interface_Alias, Set_Abstract_Interface_Alias): New
	subprograms.
	(Access_Disp_Table, Set_Access_Disp_Table): Modified to handle a list of
	entities rather than a single node.
	(Is_Interface, Set_Is_Interface): New subprogram
	(First_Tag_Component): New syntesized attribute

	(Write_Field25_Name): Upgraded to write Abstract_Interface_Alias
	(Task_Body_Procedure): New subprogram to read this attribute.
	(Set_Task_Body_Procedure): New subprogram to set this attribute.
	(Has_Controlled_Component): Now applies to all entities.
	This is only a documentation change, since it always worked to apply
	this to other than composite types (yielding false), but now this is
	official.
	Update documentation on Must_Be_Byte_Aligned for new spec

	* tbuild.adb, exp_dist.adb, exp_disp.adb, exp_ch3.ads, exp_ch3.adb,
	exp_attr.adb, exp_aggr.adb, exp_ch4.adb, exp_ch5.adb: Upgrade all the
	uses of the Access_Disp_Table attribute to reference the first dispatch
	table associated with a tagged type. As
	part of the implementation of abstract interface types,
	Access_Disp_Table has been redefined to contain a list of dispatch
	tables (rather than a single dispatch table).
	Similarly, upgrade all the references to Tag_Component by the
	new attribute First_Tag_Component.
	(Find_Inherited_TSS): Moved to exp_tss.
	Clean up test in Expand_N_Object_Declaration for cases
	where we need to do a separate assignment of the initial value.
	(Expand_N_Object_Declaration): If the expression in the
	declaration of a tagged type is an aggregate, no need to generate an
	additional tag assignment.
	(Freeze_Type): Now a function that returns True if the N_Freeze_Entity
	is to be deleted.
	Bit packed array ops are only called if operands are known to be
	aligned.
	(Component_Equality): When returning an N_Raise_Program_Error statement,
	ensure that its Etype is set to Empty to avoid confusing GIGI (which
	expects that only expressions have a bona fide type).
	(Make_Tag_Ctrl_Assignment): Use Build_Actual_Subtype to correctly
	determine the amount of data to be copied.

	* par.adb (P_Interface_Type_Definition): New subprogram that parses the
	new syntax rule of Ada 2005 interfaces (for AI-251 and AI-345):
	    INTERFACE_TYPE_DEFINITION ::=
	      [limited | task | protected | synchronized] interface
		[AND interface_list]

	* par-ch3.adb (P_Type_Declaration): Modified to give support to
	interfaces.
	(P_Derived_Type_Def_Or_Private_Ext_Decl): Modified to give support to

	(Interface_List, Set_Interface_List): New subprograms.
	(Interface_Present, Set_Interface_Present): New subprograms.
	(Limited_Present, Set_Limited_Present): Available also in derived
	type definition nodes.
	(Protected_Present, Set_Protected_Present): Available also in
	record type definition and
	derived type definition nodes.
	(Synchronized_Present, Set_Synchronized_Present): New subprograms.
	(Task_Present, Set_Task_Present): New subprogram.
	(Task_Body_Procedure): Removed.
	(Set_Task_Body_Procedure): Removed.
	These subprogram have been removed because the attribute
	Task_Body_Procedure has been moved to the corresponding task type
	or task subtype entity to leave a field free to store the list
	of interfaces implemented by a task (for AI-345)
	Add Expression field to N_Raise_Statement node for Ada 2005 AI-361
	(Null_Exclusion_Present): Change to Flag11, to avoid conflict with
	expression flag Do_Range_Check
	(Exception_Junk): Change to Flag7 to accomodate above change
	(Box_Present, Default_Name, Specification, Set_Box_Present,
	Set_Default_Name, Set_Specification): Expand the expression
	"X in N_Formal_Subprogram_Declaration" into the corresponding
	two comparisons. Required to use the csinfo tool.

	* exp_ch11.adb (Expand_N_Raise_Statement): Deal with case where
	"with string" given.

	* sem_ch11.adb (Analyze_Raise_Statement): Handle case where string
	expression given.

	* par-ch11.adb (P_Raise_Statement): Recognize with string expression
	in 2005 mode

	* exp_ch9.adb (Build_Task_Proc_Specification): Modified to use entity
	attribute Task_Body_Procedure rather than the old semantic field that
	was available in the task_type_declaration node.

	* par-ch12.adb (P_Formal_Type_Definition): Modified to handle formal
	interface type definitions.
	(P_Formal_Derived_Type_Definition): Modified to handle the list of
	interfaces.

	* par-ch9.adb (P_Task): Modified to handle the list of interfaces in a
	task type declaration.
	(P_Protected): Modified to handle the list of interfaces in a
	protected type declaration.

	Original_Record_Component if Present and not the entity.
	(gnat_to_gnu_entity, case E_Record_Subtype): Rework handling of subtypes
	of tagged extension types by not making field for components that are
	inside the parent.
	(gnat_to_gnu_entity) <E_Record_Type>: Fix typo in the alignment formula
	(gnat_to_gnu_entity) <E_Variable>: Do not convert again the
	expression to the type of the object when the object is constant.
	Reverse defer_debug_incomplete_list before traversing it, so that trees
	are processed in the order at which they were added to the list. This
	order is important when using the stabs debug format.
	If we are deferring the output of debug information, also defer this
	output for a function return type.
	When adding fields to a record, prevent emitting debug information
	for incomplete records, emit the information only when the record is
	complete.
	(components_to_record): New parameter defer_debug.
	(gnat_to_gnu_entity, case E_Array_Subtype): Call copy_alias_set.
	(gnat_to_gnu_field_decl): New function.

	Expansion_Delayed and handle case when it's inside an
	N_Qualified_Expression.

	* sem_ch3.adb (Derived_Type_Declaration): New predicate
	Comes_From_Generic, to recognize accurately that the parent type in a
	derived type declaration can be traced back to a formal type, because
	it is one or is derived from one, or because its completion is derived
	from one.

	Corresponding_Discriminant.
	(gnat_to_gnu) <N_Return_Statement>: Restructure. If the
	function returns "by target", dereference the target pointer using the
	type of the actual return value.
	<all>: Be prepared for a null gnu_result.
	(processed_inline_subprograms): Check flag_really_no_inline
	instead of flag_no_inline.

	* exp_pakd.adb (Create_Packed_Array_Type): Do not set
	Must_Be_Byte_Aligned for cases where we do not need to use a
	System.Pack_nn unit.

	* exp_ch6.adb (Expand_Call): Call Expand_Actuals for functions as well
	as procedures.
	Needed now that we do some processing for IN parameters as well. This
	may well fix some unrelated errors.
	(Expand_Call): Handle case of unaligned objects (in particular those
	that come from packed arrays).
	(Expand_Inlined_Call): If the subprogram is a renaming as body, and the
	renamed entity is an inherited operation, re-expand the call using the
	original operation, which is the one to call.
	Detect attempt to inline parameterless recursive subprogram.
	(Represented_As_Scalar): Fix to work properly with private types
	(Is_Possibly_Unaligned_Object): Major rewrite to get a much more
	accurate estimate. Yields True in far fewer cases than before,
	improving the quality of code that depends on this test.

	* exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
	over both visible and private declarations to remove them from tree,
	and mark subprograms declared in package as eliminated, to prevent
	spurious use in subsequent compilation of generic units in the context.

	* exp_util.ads: Minor cleanup in variable names

	* sem_eval.ads, sem_eval.adb: Minor reformatting
	(Compile_Time_Known_Bounds): New function

	* exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
	that appears in the instantiation rather than the internal subtype
	generated in the wrapper package, to avoid anomalies in gigi when the
	target is derived from a private type whose full view is an access type.

2005-03-15  Robert Dewar  <dewar@adacore.com>

	* exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,

2005-03-15  Thomas Quinot  <quinot@adacore.com>

	* exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
	here from exp_attr so it can be shared between exp_attr and exp_dist.
	(TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
	all TSS names, not a subset thereof, and the previous name introduced
	an unnecessarily confusion that a distinction might exist between
	"OK" TSS names and some "not OK" TSS names.

2005-03-15  Doug Rupp  <rupp@adacore.com>

	PR ada/6852
	This change works fine when gnatlib is built from the gcc directory,
	but does not work when using the libada Makefile, since GCC_FOR_TARGET
	is not passed to ada/Makefile.in, so more work is needed by a
	Makefile/configure expert.

	* Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
	set GMEM_LIB on ia64 linux to add optional support for gnatmem.
	Setup gnatlink switch -M for x86_64 linux, as it is already setup
	for Linux x86.
	(gnatlib-shared-default): Use GNATLIBCFLAGS as well.
	Run ranlib on libgccprefix.a
	Define PREFIX_OBJS for Darwin, to build libgccprefix.
	(ADA_INCLUDE_SRCS): Split Ada packages.

	capabilities for categorizing characters using Unicode categories

2005-03-15  Ed Schonberg  <schonberg@adacore.com>

	* sem_ch10.adb (Build_Ancestor_Name): If the ancestor is an
	instantiation that has been rewritten as a package body, retrieve spec
	to generate proper name for implicit_with_clause.
	(Install_Parents): Recognize a parent that is an instantiation but has
	been rewritten as a package declaration during analysis.

2005-03-15  Javier Miranda  <miranda@adacore.com>
	    Ed Schonberg  <schonberg@adacore.com>

	* sem_ch12.adb (Instantiate_Object): If the analysis of the actual
	parameter reported some error we immediately return. This improves the
	behaviour of the frontend in case of errors.
	(Install_Parent, Remove_Parent): Introduce new flag
	Parent_Unit_Visible, to preserve the proper visibility of the ultimate
	ancestor of a generic child unit, when the child is being instantiated.
	(Inline_Instance_Body): If we are compiling the private
	part or the body of a child unit, restore the proper visibility of the
	parents after compiling the instance body.

	PR ada/15608
	* sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
	of a private type, in which case it is underlying_type that denotes
	the proper task. Also modified to use the new entity attribute
	that is directly available in the task type and task subtype entities
	(Build_Actual_Subtype_Of_Component): Handle properly multidimensional
	arrays when other dimensions than the first are constrained by
	discriminants of an enclosing record.
	(Insert_Explicit_Dereference): If the prefix is an indexed component or
	a combination of indexed and selected components, find ultimate entity
	and generate the appropriate reference for it, to suppress spurious
	warnings.
	(Note_Possible_Modification): If an entity name has no entity, return.
	(Is_Variable): A function call never denotes a variable.
	(Requires_Transient_Scope): For record types, recurse only on
	components, not on internal subtypes that may have been generated for
	constrained components.

2005-03-15  Ed Schonberg  <schonberg@adacore.com>

	* sem_ch4.adb (Analyze_Concatenation): Do not consider operators marked
	Eliminated as candidates for resolution. Both efficient, and avoids

	(Process_Implicit_Dereference_Prefix): Use this procedure whenever
	expansion is disabled (as when compiling a generic) to prevent spurious
	warnings on prefixes of selected components.

	attached to a list before checking whether it appears in the private
	declarations of the current package.
	(Make_Inequality_Operator): Insert declaration in proper declarative
	list rather than just setting the Parent field, so that
	Is_Private_Declaration can handle it properly.

2005-03-15  Ed Schonberg  <schonberg@adacore.com>

	* sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic, if this is

	Currently we don't permit this, but this is under discussion by the
	ARG, and it is easy enough to use a different example.

	* s-wchcon.ads, s-wchcnv.ads, s-wchcnv.adb: Add new subprograms for

	subprogram only if inner one comes from source.
	(Analyze_Function_Call): If the call is given in object notation, the

	a tag-indeterminate function call whose type is an ancestor of the
	containing call's associated tagged type. This situation can occur

2005-02-09  Arnaud Charlet  <charlet@adacore.com>

	PR ada/16592

2005-02-09  Ed Schonberg  <schonberg@adacore.com>

	* sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
	with expansion disabled. The actual subtype is needed among other
	places when the selected component appears in the context of a loop
	bound, and denotes a packed array.
	(Operator_Check): Always use the first subtype in the
	error message, to avoid the appearance of internal base types.
	(Transform_Object_Operation): Copy each actual in full
	to the parameter associations of the constructed call, rather than
	using the shallow copy mechanism of New_Copy_List. This ensures that
	the chaining of named associations is done properly.
	(Complete_Object_Operation): Rewrite node, rather than
	replacing it, so that we can trace back to the original selected
	component.

	* sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,

	imposes an elaboration constraint between two packages.

2005-02-09  Ed Schonberg  <schonberg@adacore.com>

	* sem_ch7.adb (Uninstall_Declarations): Exchange full and private
	views of a private type after handling its private dependents, to

	identifier.

	the difference between compact and incompact layout and add the record
	representation clause to the example illustrating different layouts.
	Add the description of '-A5' gnatpp option ("align 'AT' keywords in
	component clauses").

2005-02-09  Florian Villoing  <villoing@adacore.com>

	* gnat_ugn.texi: Fix typos.
	Use @command to display 'gcc', 'gnatbind', etc. insted of @code or
	@file.
	Make proper use of @ref, @xref and @pxref to avoid duplication of "see"
	in the generated documentation.

2005-02-09  Jose Ruiz  <ruiz@adacore.com>

	* s-osinte-vxworks.ads (taskPriorityGet): Add this function (imported
	from the VxWorks kernel) that is needed for getting the active
	priority of the different tasks.

	* s-atacco.ads, s-atacco.adb (Nothing): Remove this dummy procedure.
	Use a pragma Elaborate_Body in the spec file instead.

	TYPE_SIZE_UNIT of result type if SIZE is not specified.
	(make_aligning_type): Pass -1 as ADDRESSABLE to prevent the creation

	* sem_util.adb (Insert_Explicit_Dereference): When an implicit
	dereference is rewritten to an explicit one, generate a reference to
	the entity denoted by its prefix using the original prefix node, so

	emitting 'assigned but never read' warning on a variable on the basis
	that it has an access type.

	subprogram which is Imported with convention Intrinsic if an
	External_Name argument is specified.

	ensure proper recording of references.

2004-12-07  Gary Dismukes  <dismukes@adacore.com>

	* gigi.h (others_decl, all_others_decl): New decls representing the

	(Insert_Partition_Check): Remove fossile code.
	(First_RCI_Subprogram_Id): Document this constant.
	(Add_RAS_Access_TSS): Correct the setting of the Etype of the
	RAS_Access TSS.
	(Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
	replaced with calls to Get_Library_Unit_Name_String. Previously there
	were several instances of the same code in different locations in the
	compiler; this checkin completes the replacement of all of these
	instances with calls to a common subprogram.
	Minor reformatting.

	* sem_dist.adb: Remove comment noting that RPC receiver generation
	should be disabled for RACWs that implement RASs.
	(Process_Partition_Id): Use new subprogram Get_Library_Unit_Name_String.

	* sem_util.ads, sem_util.adb (Has_Stream): New function
	(Get_Library_Unit_Name_String): New subprogram to retrieve the fully
	qualified name of a library unit into the name buffer.
	(Note_Possible_Modification): Generate a reference only
	if the context comes from source.

	* snames.ads (PCS_Names): New subtype corresponding to names of
	supported implementations of the Partition Communication Subsystem
	(PCS) (i.e. the runtime library support modules for the distributed
	systems annex).

	    Ed Schonberg  <schonberg@adacore.com>

	* einfo.ads, einfo.adb: Remove Is_Psected flag, no longer used
	(Has_Rep_Pragma): New function
	(Has_Attribute_Definition_Clause): New function
	(Record_Rep_Pragma): Moved here from sem_ch13.adb
	(Get_Rep_Pragma): Remove junk kludge for Stream_Convert pragma

	* sem_ch13.ads, sem_ch13.adb (Record_Rep_Pragma): Moved to einfo.adb

	* exp_prag.adb: (Expand_Pragma_Common_Object): New procedure
	(Expand_Pragma_Psect_Object): New procedure
	These procedures contain the revised and cleaned up processing for
	these two pragmas. This processing was formerly in Sem_Prag, but
	is more appropriately moved here. The cleanup involves making sure
	that the pragmas are properly attached to the tree, and that no
	nodes are improperly shared.

	* sem_prag.adb: Move expansion of Common_Object and Psect_Object
	pragmas to Exp_Prag, which is more appropriate.
	Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to
	check for duplicates Remove use of Is_Psected flag, no longer needed.
	Use new Make_String_Literal function with string.

	* exp_attr.adb (Expand_Fpt_Attribute): The floating-point attributes
	that are functions return universal values, that have to be converted
	to the context type.
	Use new Make_String_Literal function with string.
	(Get_Stream_Convert_Pragma): New function, replaces the use of
	Get_Rep_Pragma, which had to be kludged to work in this case.

	* freeze.adb: Use new Has_Rep_Pragma function

	* exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
	function with string.
	Use new Has_Rep_Pragma function.

	* tbuild.ads, tbuild.adb (Make_String_Literal): New function, takes
	string argument.

2004-11-18  Robert Dewar  <dewar@adacore.com>

	* errout.ads, errout.adb: (First_Sloc): New function

	* par-ch5.adb (P_Condition): Check for redundant parens is now a style
	check (-gnatyx) instead of being included as a redundant construct
	warning.

	* sem_ch6.adb: Change name Style_Check_Subprogram_Order to
	Style_Check_Order_Subprograms.

	* style.ads, styleg.ads, styleg.adb, styleg-c.adb, stylesw.ads,
	stylesw.adb: Add Style_Check_Xtra_Parens

	* usage.adb: Add line for -gnatyx (check extra parens)

	* vms_data.ads: Add entry for STYLE_CHECKS=XTRA_PARENS => -gnatyx

2004-11-18  Ed Schonberg  <schonberg@adacore.com>
	    Robert Dewar  <dewar@adacore.com>

	* exp_ch4.adb (Expand_N_Selected_Component): If the component is the
	discriminant of a constrained subtype, analyze the copy of the
	corresponding constraint, because in some cases it may be only
	partially analyzed.
	Removes long-lived ??? comments.

	* exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
	handled controlled or secondary-stack expressions within the
	iteration_scheme of a loop.

	* sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
	bounds that may contain functions calls, to prevent memory leaks when
	the bound contains a call to a function that uses the secondary stack.
	(Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
	generate temporaries for loop bounds that might contain function calls
	that require secondary stack and/or finalization actions.

	* sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
	selected component and the selector is overloadable (not just a
	function) treat as function call, Analyze_Call will disambiguate if
	necessary.
	(Analyze_Selected_Component): Do not generate an actual subtype for the
	selected component if expansion is disabled. The actual subtype is only
	needed for constraint checks.
	(Analyze_Allocator): If restriction No_Streams is set, then do
	not permit objects to be declared of a stream type, or of a
	composite type containing a stream.

	* restrict.ads: Remove the a-stream entry from Unit_Array, since
	No_Streams no longer prohibits with'ing this package.

	* sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
	discriminants, but the parent base has unknown discriminants, there is
	no discriminant constraint to inherit. Such a discrepancy can arise
	when the actual for a formal type with unknown discriminants is a
	similar private type whose full view has discriminants.
	(Analyze_Object_Declaration): If restriction No_Streams is set, then
	do not permit objects to be declared of a stream type, or of a
	composite type containing a stream.

2004-11-18  Ed Schonberg  <schonberg@adacore.com>

	* exp_dbug.ads: Update documentation to reflect simpler encoding for
	protected operations.

	* exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
	generated name, it complicates decoding in gdb and hinders debugging
	of protected operations.
	(Build_Barrier_Function_Specification): Set the Needs_Debug_Info
	flag for the protected entry barrier function.
	(Build_Protected_Entry_Specification): Set the Needs_Debug_Info
	flag for the protected entry function.

2004-11-18  Nicolas Setton  <setton@adacore.com>

	* expect.c: Define __unix__ when __APPLE__ is defined.

	* Makefile.in: Inform the value of the variable GMEM_LIB in the
	Darwin-specific section.

	* lang-specs.h: Change the placement of the %1 marker.
	Works around the fact that gcc adds -fPIC by default under Darwin.

2004-11-18  Ed Schonberg  <schonberg@adacore.com>

	* exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
	type of the object with the packed array type, set the Analyzed flag
	on the object if it is an entity or simple indexed component, to avoid
	spurious type errors.

2004-11-18  Gary Dismukes  <dismukes@adacore.com>

	* gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb, gnatlink.adb,
	gnatls.adb, gnatxref.adb, gprep.adb: Output the copyright message on a
	separate line from the version message.

2004-11-18  Ed Falis  <falis@adacore.com>

	* init.c (__gnat_map_signal): map SIGSEGV to Storage_Error for AE653
	vthreads.
	(init_float): Eliminate initialization of floating point status for
	AE653. The instructions have no effect for vThreads.

2004-11-18  Vincent Celier  <celier@adacore.com>

	* make.adb (Gnatmake): Invoke gnatlink with -shared-libgcc when
	gnatbind is invoked with -shared.

2004-11-18  Jose Ruiz  <ruiz@adacore.com>

	* s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
	for Detect_Blocking which is redundant with the check done within the
	procedure Protected_Single_Entry_Call.
	(Lock_Read_Only_Entry): Remove the code for raising Program_Error for
	Detect_Blocking which is redundant with the check done within the
	procedure Protected_Single_Entry_Call.

2004-11-18  Vincent Celier  <celier@adacore.com>

	* makegpr.adb (Compile): Put the compiling switches (in package
	Compiler and on the command line) immediately after "-c", instead of
	at the end of the command line invocation of the compiler, when
	compiling a non-Ada file.
	(Build_Global_Archive): When there is no need to rebuild the archive,
	set Global_Archive_Exists, so that the archive is passed to the linker
	if one is needed.

2004-11-18  Robert Dewar  <dewar@adacore.com>
	    Sergey Rybin  <rybin@adacore.com>

	* gnat_ugn.texi:
	Remove extra paren check from list of checks for redundant constructs
	Add documentation of new -gnatyx style check (check extra parens)
	Remove paragraph about gnatelim debug options.

	* gnat_rm.texi: Document that Ada.Streams now forbids creating stream
	objects rather than forbidding dependencies on the package Ada.Streams.

	* sinfo.ads: Add ??? note that we should document pragmas passed to
	back end.

	* g-expect.ads: Fix a few typos in the comments.

2004-11-09  Joseph S. Myers  <joseph@codesourcery.com>

	* misc.c (gnat_handle_option): Use %< and %> for quoting in
	warning message.

	* g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
	(C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
	there is no use of GNAT.Sockets.Constants.
	Remove remaining pragma Import for C_Write
	Remove C_Read and C_Write from internal implementation unit
	GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
	the read and write functions from the system runtime library is fine
	on UNIX but won't work under Windows).

	* g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
	(Check_Selector): Use C_Recv instead of C_Read.
	Selectors are the GNAT.Sockets abstraction to perform a select()
	call on a set of descriptors. To allow abortion of an ongoing
	select operation, some data is written to a dedicated socket that
	is always monitored.
	Under Windows, the write and read library functions cannot operate
	on sockets, so we need to use send and recv instead, which is portable
	across all supported platforms.

	* g-socthi.ads: Remove C_Read and C_Write from internal implementation
	unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
	(using the read and write functions from the system runtime library is
	fine on UNIX but won't work under Windows).

2004-10-26  Nicolas Setton  <setton@act-europe.fr>

	* mlib-tgt-darwin.adb: New file.

	* mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
	mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
	mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
	mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
	subprogram body.

	* Makefile.in: Add support for building shared libraries under Darwin.
	(EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
	the low level EH init subprogram to be called from __gnat_initialize.

	* mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
	indicates which options to pass to the archive indexer.

	* mlib-utl.adb: Add support for calling ranlib with additional
	options. This is needed for instance under Mac OS X.
	(Ranlib_Options): New global variable, used to store the potential
	options to pass to ranlib.
	(Ar): Use Ranlib_Options when spawning ranlib.
	(Initialize): Set the value of ranlib option.

2004-10-26  Olivier Hainque  <hainque@act-europe.fr>

	* s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
	instead of 8K, to reflect the real potential needs for stack-checking
	in the ZCX case.

2004-10-26  Pascal Obry  <obry@gnat.com>

	* s-parame-mingw.adb (Default_Stack_Size): Add some comments.

	* s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
	Windows only the initial thread stack size can be set so it is good to
	start we a low stack size.
	The OS will adjust the size as needed.

2004-10-26  Olivier Hainque  <hainque@act-europe.fr>
	    Nicolas Setton  <setton@act-europe.fr>

	* expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
	"__unix__" instead of "unix".
	The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
	sections were just mistakenly ignored. The former is
	implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
	Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
	of hpux. This prevents an unwanted definition of the symbol
	convert_addresses in adaint.o.

2004-10-26  Gary Dismukes  <dismukes@gnat.com>

	* a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
	compatibility with type Unwind_Word on 16-bit targets such as AAMP.

2004-10-26  Cyrille Comar  <comar@act-europe.fr>

	* a-filico.ads, a-filico.adb: fix incorrect header.

	* sem_ch4.adb: Minor reformatting.

2004-10-26  Ed Schonberg  <schonberg@gnat.com>

	* checks.adb (Expr_Known_Valid): If floating-point validity checks are
	enabled, check the result of unary and binary operations when the
	expression is the right-hand side of an assignment.

2004-10-26  Vincent Celier  <celier@gnat.com>

	* clean.adb (Delete): Do not output warnings when in quiet output and
	not in verbose mode.
	(Force_Deletions): New Boolean flag, defaulted to False
	(Delete): Only delete a file if it is writable, and when
	Force_Deletions is True.
	(Parse_Cmd_Line): New switch -f: set Force_Deletions to True
	(Usage): Line for new switch -f
	(Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
	own.

2004-10-26  Eric Botcazou  <ebotcazou@act-europe.fr>

	* decl.c (gnat_to_gnu_field): Use the type of the inner object for a
	JM type only if its size matches that of the wrapper.  When a size is
	prescribed and the field is not aliased, remove the wrapper of a JM
	type only if the size is not greater than that of the packed array.
	(gnat_to_gnu_entity): Change the extension of packed array wrappers
	from LJM to JM.

2004-10-26  Geert Bosch  <bosch@gnat.com>

	* eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
	(Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
	(Pred): Implement in terms of Succ.

2004-10-26  Ed Schonberg  <schonberg@gnat.com>

	* exp_aggr.adb (Safe_Component): An aggregate component that is an
	unchecked conversion is safe for in-place use if the expression of the
	conversion is safe.
	(Expand_Array_Aggregate): An aggregate that initializes an allocator may
	be expandable in place even if the aggregate does not come from source.
	(Convert_Array_Aggr_In_Allocator): New procedure to initialize the
	designated object of an allocator in place, rather than building it
	first on the stack. The previous scheme forces a full copy of the array,
	and may be altogether unsusable if the size of the array is too large
	for stack allocation.

2004-10-26  Robert Dewar  <dewar@gnat.com>

	* exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
	compares if the component is atomic.

	* exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
	array assignment if the component type is atomic.

2004-10-26  Ed Schonberg  <schonberg@gnat.com>
	    Eric Botcazou  <ebotcazou@act-europe.fr>

	* exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
	is aliased and is a by_reference type, do not pass by copy.
	(Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
	detect whether the call is in the right side of an assignment or
	the expression of an object declaration.  Recurse on component
	association within aggregates.
	Call it in the condition that determines whether the temporary is
	necessary for correct stack-checking.

2004-10-26  Thomas Quinot  <quinot@act-europe.fr>

	* exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
	RACW_Type, used in the PolyORB version.
	Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
	version and the GARLIC version.

	* snames.ads, snames.adb, s-parint.ads, s-parint.adb:
	Rename RCI_Info to RCI_Locator for better consistency between the
	GARLIC and PolyORB versions of the distributed systems annex.
	(DSA_Implementation_Name): This enumeration lists the possible
	implementations of the Partition Communication Subsystem for the
	Distributed Systems Annex (DSA). The three available implementations
	are the dummy stub implementation (No_DSA), and two versions based on
	two different distribution runtime libraries: GARLIC and PolyORB. Both
	the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
	technology.
	Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
	that organization.

	* rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
	between the GARLIC and PolyORB versions of the distributed systems
	annex.
	Remove RE_Unbounded_Reclaim_Pool since it is unused.

2004-10-26  Gary Dismukes  <dismukes@gnat.com>

	* gnat1drv.adb: Suppress calling the back end when
	Frontend_Layout_On_Target is true.

2004-10-26  Thomas Quinot  <quinot@act-europe.fr>

	* g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
	Set_Read_Only): New subprograms.
	These new routines allow the user to set or unset the Owner execute
	and Owner write permission flags on a file.

	* makegpr.adb, mlib.adb, mlib-prj.adb: Use
	GNAT.OS_Lib.Set_Executable instead of rolling our own.

2004-10-26  Matthew Gingell  <gingell@gnat.com>

	* i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.

2004-10-26  Pascal Obry  <obry@gnat.com>

	* init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
	memory before the faulting page we properly test the process read
	access for this address using appropriate Win32 routine.
	(HPUX sections): guard with "__hpux__" instead of "hpux".

2004-10-26  Robert Dewar  <dewar@gnat.com>

	* lib-xref.adb (Generate_Reference): Don't complain about reference to
	entry parameter if pragma Unreferenced set, since we do not properly
	handle the case of multiple parameters.

2004-10-26  Vincent Celier  <celier@gnat.com>

	* prj-env.adb: (Contains_ALI_Files): New Boolean function
	(Ada_Objects_Path.Add): For a library project, add to the object path
	the library directory only if there is no object directory or if the
	library directory contains ALI files.
	(Set_Ada_Paths.Add.Recursive_Add): Ditto

2004-10-26  Vincent Celier  <celier@gnat.com>

	* prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
	extension of library projects.

	* prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
	path defaults to ".:<prefix>/lib/gnat".
	(Parse): For an extending all project, allow direct import of a project
	that is virtually extended.

	* prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
	the specified name is directly imported, return its ID. Otherwise, if
	an extension of this project is imported, return the ID of the
	extension.

2004-10-26  Robert Dewar  <dewar@gnat.com>

	* s-arit64.adb: (Le3): New function, used by Scaled_Divide
	(Sub3): New procedure, used by Scaled_Divide
	(Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
	correct more than one instance of failure to propagate carries
	correctly.
	(Double_Divide): Handle overflow case of largest negative number
	divided by minus one.

	* s-arit64.ads (Double_Divide): Document that overflow can occur in
	the case of a quotient value out of range.
	Fix comments.

2004-10-26  Robert Dewar  <dewar@gnat.com>

	* s-bitops.adb (Bit_Eq): Remove redundant check.

	* s-bitops.ads: Minor comment updates
	Change some occurrences of Address to System.Address

	* s-carsi8.ads: Fix minor cut-and-paste error in comments

2004-10-26  Ed Schonberg  <schonberg@gnat.com>

	* sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
	accessibility check to prefix that is a protected operation.

2004-10-26  Ed Schonberg  <schonberg@gnat.com>

	* sem_ch10.adb (Optional_Subunit): If file of expected subunit is
	empty, post message on stub.

2004-10-26  Ed Schonberg  <schonberg@gnat.com>
	    Javier Miranda  <miranda@gnat.com>

	* sem_ch12.adb (In_Main_Context): Predicate to determine whether the
	current instance appears within a unit that is directly in the context
	of the main unit.
	Used to determine whether the body of the instance should be analyzed
	immediately after its spec, to make its subprogram bodies available
	for front-end inlining.
	(Analyze_Formal_Array_Type): Cleanup condition that checks that range
	constraint is not allowed on the component type (AARM 12.5.3(3))

2004-10-26  Cyrille Comar  <comar@act-europe.fr>

	* sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
	'Storage_Pool): enhance, document & limit detection of non-sharable
	internal pools.

	* impunit.adb: Make System.Pool_Global and System.Pool_Local visible.

	* s-pooglo.ads: Add more documentation now that this pool is properly
	documented.

2004-10-26  Ed Schonberg  <schonberg@gnat.com>

	* sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
	or protected type with discriminants, do not constrain the
	corresponding record type if the subtype declaration has no
	discriminant constraints. This can be the case in source code, or in
	the subtype declaration created to rename an actual type within an
	instantiation.

2004-10-26  Ed Schonberg  <schonberg@gnat.com>

	* sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
	different kind of stub (possibly wrong name for file), do not check
	for conformance.
	(Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
	includes call to some function that returns an unconstrained type, do
	not inline.

2004-10-26  Ed Schonberg  <schonberg@gnat.com>

	* sem_elab.adb (Check_Elab_Call): Do not check a call that does not
	appear in the code for the main unit. Dependencies among units in the
	context of the main unit are established when those other units are
	compiled. Otherwise spurious elaboration constraints can generate
	incorrect elaboration circularities.

2004-10-26  Thomas Quinot  <quinot@act-europe.fr>
	    Ed Schonberg   <schonberg@gnat.com>

	* sem_util.adb (Is_Aliased_View): Defend against the case where this
	subprogram is called with a parameter that is not an object name. This
	situation arises for some cases of illegal code, which is diagnosed
	later, and in this case it is wrong to call Is_Aliased, as that might
	cause a compiler crash.
	(Explain_Limited_Type): Refine previous fix to include
	inherited components of derived types, to provide complete information.

	* exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
	is the prival for a protected object.
	It is necessary to mark this entity as a variable, in addition to
	flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
	modified to avoid checking the Aliased flag on entities that are not
	objects. (Checking that flag for non-objects is erroneous and could
	lead to a compiler crash).

2004-10-26  Robert Dewar  <dewar@gnat.com>

	* s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
	X_Frac = 0.5, then we know that the number X must be positive.
	(Succ): Remove the same redundant test, and also fix the primary test
	to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.

	    Vasiliy Fofanov  <fofanov@act-europe.fr>
	    Vincent Celier   <celier@gnat.com>

	* gnat_ugn.texi: Generalize "finding memory problems" section into a
	"memory management issues" section and document some of the useful
	memory pools provided as part of the GNAT library.
	Remove "virtual" from declaration of A::method2 in
	the simple example of Ada/C++ mixed system.
	Library Projects may be virtually extended: their virtual extensions

	other x86 platforms).

2004-10-04  Olivier Hainque  <hainque@act-europe.fr>

	* s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense

2004-10-04  Olivier Hainque  <hainque@act-europe.fr>

	* init.c (__gnat_initialize): Call an Ada subprogram to perform the
	table registration calls when need be. Ensures no reference to the crt
	ctors symbol are issued in the SJLJ case, which avoids possible
	undefined symbol errors in the case of modules to be statically linked
	with the kernel.

2004-10-04  Javier Miranda  <miranda@gnat.com>

	* sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
	in-line the code corresponding to subprogram Analyze_Actuals. In
	addition, analyze the actuals only in case of subprogram call.

	(XMatchD): Avoid warning for Logic_Error call

2004-10-04  Robert Dewar  <dewar@gnat.com>

	* exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
	consider expressions buried within a procedure actual to be an actual.
	This caused some blowups with uses of packed slices within a procedure
	actual.

2004-10-04  Robert Dewar  <dewar@gnat.com>

	* exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
	longer need to be initialized to zero.
	(Get_Simple_Init_Val): Modular packed arrays no longer need to be
	initialized to zero.

	* checks.adb (Expr_Known_Valid): Packed arrays are now always
	considered valid, even if the representation is modular. That's correct
	now that we no longer initialize packed modular arrays to zero.

	* exp_dbug.ads: Clarify documentation on handling of PAD and JM
	suffixes. These are now documented as the only cases in which the
	debugger ignores outer records.
	Previously, the spec allowed arbitrary suffixes for this purpose.
	Change name of LJM to JM for packed array pad records
	Create separate section on packed array handling, and add a whole new
	set of comments to this section describing the situation with packed
	modular types and justification requirements depending on endianness.

2004-10-04  Robert Dewar  <dewar@gnat.com>

	when in Configurable_Run_Time mode.

2004-10-04  Ed Schonberg  <schonberg@gnat.com>

	* sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
	class_wide type after component list has been inherited.

2004-10-04  Ed Schonberg  <schonberg@gnat.com>

	* sem_ch12.adb (Check_Generic_Actuals): New predicate
	Denotes_Previous_Actual, to handle properly the case of a private
	actual that is also the component type of a subsequent array actual.
	The visibility status of the first actual is not affected when the
	second is installed.
	(Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
	make fully recursive the treatment of formals of packages declared
	with a box.
	(Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
	the above on exit from an instantiation.
	(Denotes_Formal_Package): When called from Restore_Private_Views, ignore
	current instantiation which is now complete.
	(Analyze_Package_Instantiation): No instantiated body is needed if the
	main unit is generic. Efficient, and avoid anomalies when a instance
	appears in a package accessed through rtsfind.

2004-10-04  Ed Schonberg  <schonberg@gnat.com>

	* exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
	do not generate a declaration for a temporary if the call is part of a
	library-level instantiation.

2004-10-04  Ed Schonberg  <schonberg@gnat.com>

	* sem_util.adb (Explain_Limited_Type): Ignore internal components when
	searching for a limited component to flag.

	* exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
	expansion of Input, to account for the fact that the implicit call
	generated by the attribute reference must freeze the user-defined
	stream subprogram. This is only relevant to 'Input, because it can
	appear in an object declaration, prior to the body of the subprogram.

	* sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
	expansion can proceed and further errors uncovered.
	(Minor clean up): Fix cases of using | instead of \ for continuation
	messages.

2004-10-04  Richard Kenner  <kenner@vlsi1.ultra.nyu.edu>

	resolved path.
	(Parse_Single_Project): Ditto.

	* prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
	Add_To_Project_Path for virtual projects.

	directory separator, if any.
	(Gprmake): Do not allow mains on the command line for library projects.
	Do not attempt to link when the project is a library project.
	(Library_Opts): New table to store Library_Options.
	(Build_Library): If Library_Options is specified, pass these options

	by the expander.

2004-10-04  Jose Ruiz  <ruiz@act-europe.fr>

	* targparm.ads, targparm.adb (Targparm_Tags): Add PAS value

	system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads,
	system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
	used to signal whether the compiler creates the required stacks and
	descriptors for the different tasks (when True) or it is done by the
	underlying operating system at run time (when False).
	It is initially set to False in all targets.

	* exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
	if it is supported by the target.
	(Make_Task_Create_Call): Pass the stack address if it has been
	previously created. Otherwise pass a Null_Address.

	* snames.adb: Add _stack.

	* snames.ads: Add Name_uStack. Required to allow the expander to
	statically allocated task stacks.

	* s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
	Stack_Address argument.

	* usage.adb: Change "pragma inline" to "pragma Inline" in information
	and error messages

2004-10-04  Thomas Quinot  <quinot@act-europe.fr>

	* exp_dist.adb: Split declaration of asynchronous flag out of
	Add_RACW_Read_Attribute.
	Minor reformatting for better alignment with PolyORB version.
	Store the entity for the asynchronous flag of an RACW, rather than the
	expression, in the asynchronous flags table. This will allow this flag
	to be used in other subprograms beside Add_RACW_Read_Attribute.

2004-10-04  Thomas Quinot  <quinot@act-europe.fr>

	* g-socket.ads, g-socket.adb, g-socthi.adb, socket.c,

	g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads:  Add new
	sockets constant MSG_NOSIGNAL (Linux-specific).
	Add new sockets constant MSG_Forced_Flags, list of flags to be set on
	all Send operations.
	For Linux, set MSG_NOSIGNAL on all send operations to prevent them
	from trigerring SIGPIPE.
	Rename components to avoid clash with Ada 2005 possible reserved
	word 'interface'.
	(Check_Selector): When the select system call returns with an error
	condition, propagate Socket_Error to the caller.

2004-09-23  Robert Dewar  <dewar@gnat.com>

	PR ada/17540

	* sem_prag.adb (Process_Import_Or_Interface): Don't set Is_Public here,

	clause).
	Change "pragma inline" to "pragma Inline" in information and error
	messages.
	Minor reformatting.

	* freeze.adb (Check_Address_Clause): Remove previous change, not the
	right way of doing things after all.
	(Freeze_Entity): For object, set Is_Public for imported entities
	unless there is an address clause present.

2004-09-21  Olivier Hainque  <hainque@act-europe.fr>

	* decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
	dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
	ensures proper handling of types with rep clauses, which might have
	their TYPE_SIZE set already.

2004-09-21  Robert Dewar  <dewar@gnat.com>

	* decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
	packed array types in both little- and big-endian cases. This change
	ensures that we no longer count on the unused bits being initialized
	for such types (and in particular ensures that equality testing will
	only read the relevant bits).
	Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
	These changes mean that we no longer need to initialize small packed
	arrays.
	(gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
	optimization to an LJM field as to its parent field.

	* ada-tree.h, trans.c, utils.c, utils2.c:
	Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P

	(end_subprog_body): Directly call cgraph_finalize_function;
	do not lower the nested functions.

2004-09-20  Robert Dewar  <dewar@gnat.com>

	PR ada/17540

	* freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public
	if an address clause is present, since that means that the Import
	should be ignored.

2004-09-20  Arnaud Charlet  <charlet@act-europe.fr>

	* 5tsystem.ads: Removed, no longer used.

2004-09-17  Jeffrey D. Oldham  <oldham@codesourcery.com>

	Prj.Attr.PM.
	(Register_New_Package (Name, Attributes), Register_New_Attribute): Raise
	Prj.Project_Error after call to Fail.
	(Register_New_Package (Name, Id)): Set Id to Empty_Package after calling
	Fail. Check that package name is not already in use.

	* prj-attr.ads: Comment updates to indicate that all subprograms may be
	used by tools, not only by the project manager, and to indicate that
	exception Prj.Prj_Error may be raised in case of problem.
	(Add_Unknown_Package, Add_Attribute): Moved to new child package
	Prj.Attr.PM.
	(Attrs, Package_Attributes): Table instantiations moved from the body to
	the private part to be accessible from Prj.Attr.PM body.

	* prj-dect.adb (Parse_Package_Declaration): Call Add_Unknown_Package
	from new package Prj.Attr.PM.

	* s-taskin.adb (Initialize_ATCB): Initialize to 0 the
	Protected_Action_Nesting.

	* s-taskin.ads: Adding the field Protected_Action_Nesting to the
	Common_ATCB record. It contains the dynamic level of protected action
	nesting for each task. It is needed for checking whether potentially
	blocking operations are called from protected operations.
	(Detect_Blocking): Adding a Boolean constant reflecting whether pragma

	Detect_Blocking is active and delay is called from a protected
	operation.

	* gnat_rm.texi: Rename GNAT.Perfect_Hash.Generators to
	GNAT.Perfect_Hash_Generators, and remove the empty GNAT.Perfect_Hash
	package.

	(Register_Receiving_Stub): Add Subp_Info formal parameter.
	Update API in placeholder implemetation of s-parint to reflect changes
	in distribution runtime library.

	* sem_ch3.adb (Expand_Derived_Record): Rename to
	Expand_Record_Extension.

	* sem_disp.adb (Check_Controlling_Formals): Improve error message for
	primitive operations of potentially distributed object types that have
	non-controlling anonymous access formals.

	* sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
	subprogram.
	New implementation of expansion for remote access-to-subprogram types,

	GNAT.Perfect_Hash package.

	* atree.adb: Minor reformatting

	* exp_ch3.adb (Expand_Derived_Record): Rename to
	Expand_Record_Extension.
	(Build_Record_Init_Proc.Build_Assignment): The default expression in
	a component declaration must remain attached at that point in the
	tree so New_Copy_Tree copies it if the enclosing record type is derived.
	It is therefore necessary to take a copy of the expression when building
	the corresponding assignment statement in the init proc.
	As a side effect, in the case of a derived record type, we now see the
	original expression, without any rewriting that could have occurred
	during expansion of the ancestor type's init proc, and we do not need
	to go back to Original_Node.

	* exp_ch3.ads (Expand_Derived_Record): Rename to
	Expand_Record_Extension.

	* exp_dist.ads, exp_dist.adb (Underlying_RACW_Type): New subprogram.

	System.Partition_Interface.Get_Unique_Remote_Pointer.

	subprograms.
	New implementation of expansion for remote access-to-subprogram types,
	based on the RACW infrastructure.

	* exp_dist.ads (Copy_Specification): Update comment to note that this
	function can copy the specification from either a subprogram
	specification or an access-to-subprogram type definition.

2004-08-13  Ed Schonberg  <schonberg@gnat.com>

	* rtsfind.adb (Entity_Not_Defined): If the error ocurrs in a predefined
	unit, this is an attempt to inline a construct that is not available in

	hand side. Warnings are now properly emitted when variables or prefixes
	are assigned but not read.

	* sem_warn.adb (Output_Unreferenced_Messages): Add additional checks to

	"variable ... is assigned but never read" since other entities may read
	the memory location.

	interpretations for rewritten right operand.
	(Set_Mixed_Mode_Operand): Handle properly a universal real operand when

	discriminated type is not referenced.

	* lib-xref.adb (Generate_Reference): A deferred constant completion,
	record representation clause or record type discriminant does not

	   calls Note_Possible_Modification on a copied tree).

	warning over '<pointer> is never assigned a value'.

	executable name when not initialized. Otherwise, use its current value.

	* osint.ads (Exec_Name): Move Exec_Name from body to spec in order to
	initialize it to another executable name than the current one. This
	allows to configure paths for an executable name (gnatmake) different
	from the current one (gnatdist).

2004-03-29  Ed Schonberg  <schonberg@gnat.com>

	* exp_ch6.adb (Expand_Call): A call to a function declared in the
	current unit cannot be inlined if it appears in the body of a withed
	unit, to avoid order of elaboration problems in gigi.

	information for protected (wrapper) operation as well, to simplify gdb
	use.

	several units. Do not include such files in the config pragmas or
	in the naming scheme.

	* prj-nmsc.adb (Record_Source): New parameter Trusted_Mode.
	Resolve links only when not in Trusted_Mode.
	(Find_Sources, Recursive_Find_Dirs, Find_Source_Dirs, Locate_Directory):
	Do not resolve links for the display names.

	resolve links when computing the display names.

2004-03-25  Thomas Quinot  <quinot@act-europe.fr>

	* sem_attr.adb (Check_Dereference): When the prefix of a 'Tag
	attribute reference does not denote a subtype, it can be any
	expression that has a classwide type, potentially after an implicit
	dereference.  In particular, the prefix can be a view conversion for
	a classwide type (for which Is_Object_Reference holds), but it can
	also be a value conversion for an access-to-classwide type. In the
	latter case, there is an implicit dereference, and the original node
	for the prefix does not verify Is_Object_Reference.

	* sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): A view
	conversion of a discriminant-dependent component of a mutable object
	is one itself.

2004-03-25  Ed Schonberg  <schonberg@gnat.com>

	* freeze.adb (Freeze_Entity): When an inherited subprogram is
	inherited, has convention C, and has unconstrained array parameters,
	place the corresponding warning on the derived type declaration rather
	than the original subprogram.

	* sem_ch12.adb (Instantiate_Formal_Subprogram): Set From_Default
	indication on renaming declaration, if formal has a box and actual
	is absent.

	* sem_ch8.adb (Analyze_Subprogram_Renaming): Use From_Default flag to
	determine whether to generate an implicit or explicit reference to
	the renamed entity.

	* sinfo.ads, sinfo.adb: New flag From_Default, to indicate that a
	subprogram renaming comes from a defaulted formal subprogram in an
	instance.

2004-03-25  Gary Dismukes  <dismukes@gnat.com>

	* sem_elab.adb (Check_Elab_Call): Refine loop that checks for default
	value expressions to ensure that calls within a component definition
	will be checked (since those are evaluated during the record type's
	elaboration).

2004-03-25  Arnaud Charlet  <charlet@act-europe.fr>

	* s-tpobop.adb: Code clean up:
	(Requeue_Call): Extract from PO_Service_Entries to remove duplicated

	declaration for a child subprogram body that acts as a spec, indicate
	that the entity in the declaration needs debugging information.

	* sem_ch3.adb (Complete_Private_Subtype): Do not build an underlying
	full view if the subtype is created for a constrained record component;
	gigi has enough information to construct the record, and there is no
	place in the tree for the declaration.

	* sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
	serial number for the dummy body that is built for analysis, to avoid
	inconsistencies in the generation of internal names when compiling
	with -gnatN.

2004-03-22  Thomas Quinot  <quinot@act-europe.fr>

	* sem_util.adb (Is_Object_Reference): A view conversion denotes an

	* ada-tree.h: Update copyright notice.
	Minor reformatting.

2004-03-19  Olivier Hainque  <hainque@act-europe.fr>

	* decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
	as regular exception objects and not as mere integers representing the
	condition code.  The latter approach required some dynamics to mask off
	severity bits, which did not fit well into the GCC table based model.
	(gnat_to_gnu_entity, objects): Don't supply an external name for VMS
	exception data objects. We don't it and it would conflict with the other
	external symbol we have to generate for such exceptions.

	* trans.c (tree_transform, case N_Exception_Handler): Remove part of
	the special code for VMS exceptions, since these are now represented
	as regular exceptions objects.

2004-03-19 Richard Kenner  <kenner@vlsi1.ultra.nyu.edu>

	* decl.c (debug_no_type_hash): Remove.
	(gnat_to_gnu_entity, case E_Array_Type): Don't set and clear it.

	Specific.Set instead of direct call to e.g pthread_setspecific.

2004-03-18  Thomas Quinot  <quinot@act-europe.fr>

	* adaint.c: Update comments.

	* Makefile.in: set PREFIX_OBJS, SYMLIB, THREADSLIB, and
	GNATLIB_SHARED for FreeBSD.

2004-03-18  Jose Ruiz  <ruiz@act-europe.fr>

	* init.c [VxWorks]: Do not fix the stack size for the environment task.
	When needed (stack checking) the stack size is retrieved
	from the VxWorks kernel.

	* Makefile.in: Flag -nostdinc is required when building the run time
	for avoiding looking for files in the base compiler.
	Add the VxWorks specific version of the package body for
	System.Stack_checking.Operations (5zstchop.adb).

	* Make-lang.in: Add the object file for
	System.Stack_Checking.Operations.

	* Makefile.rtl: Add object file for the package
	System.Stack_Checking.Operations.

	* s-stchop.ads, s-stchop.adb, 5zstchop.adb: New files.

	* s-stache.ads, s-stache.adb: Move the operations related to stack
	checking from this package to package System.Stack_Checking.Operations.
	This way, stack checking operations are only linked in the final
	executable when using the -fstack-check flag.

2004-03-18  Doug Rupp  <rupp@gnat.com>

	* Makefile.in [VMS]: Handle 64 bit specs (5qsystem.ads, 5xcrtl.ads).

	making sure that each directory is present only once and, for object
	dirs, when a directory already present is added, the duplicate is
	removed and the directory is always put as the last in the table.
	Write the path files at the end of these accumulations.

	* prj-nmsc.adb (Record_Source): Add source file name in hash table
	Files_Htable for all sources.

	* a-ngcoty.adb (Modulus): In alternate formula for large real or
	imaginary parts, use Double precision throughout.

	* a-tifiio.adb (Put_Scaled): Remove remaining pragma Debug. Not only
	we want to be able to compile run-time with -gnata for testing, but
	this may also be instantiated in user code that is compiled with -gnata.

2004-03-15  Olivier Hainque  <hainque@act-europe.fr>

	* s-stalib.ads (Exception_Code): New type, to represent Import/Export
	codes. Having a separate type for this is useful to enforce consistency
	throughout the various run-time units.
	(Exception_Data): Use Exception_Code for Import_Code.

	* s-vmextra.ads, s-vmexta.adb: Use Exception_Code instead of a mix of
	Natural and Integer in various places.

	occurrence matches some handler choice specification. Extracted out of
	get_action_description_for, and expanded to take care of the VMS
	specifities.
	(get_action_description_for): Use is_handled_by instead of an explicit
	complex condition to decide if the current choice at hand catches the
	propagated occurrence.

	* raise.h (Exception_Code): New type for C.

	* rtsfind.ads (RE_Id, RE_Unit_Table): Add
	System.Standard_Library.Exception_Code, to allow references from the

	New accessors to allow easy access to GNAT exception data
	characteristics.
	(GNAT_GCC_Exception record, Propagate_Exception): Get rid of the
	redundant Handled_By_Others component, helper for the personality
	routine which will now be able to call the appropriate exception data
	accessor instead.

	* cstand.adb (Create_Standard): Adjust the type of the Import_Code
	component of Standard_Exception_Type to be the closest possible to
	Exception_Code in System.Standard_Library, that we cannot get at this
	point. Expand a ??? comment to notify that this type node should
	probably be rewritten later on.

	* exp_prag.adb (Expand_Pragma_Import_Export_Exception): Adjust the
	registration call to include a pointer to the exception object in the
	arguments.

	* init.c (__gnat_error_handler): Use Exception_Code and Base_Code_In

	longer needed now that it is in the spec of
	System.Tasking.Task_Attributes.

	* g-os_lib.ads, g-os_lib.adb (Create_Output_Text_File): New function.

	* make.adb (Gnatmake): Do not check the executable suffix; it is being
	taken care of in Scan_Make_Arg.
	(Scan_Make_Arg): Add the executable suffix only if the argument
	following -o, in canonical case, does not end with the executable
	suffix.  When in verbose mode and executable file name does not end
	with executable suffix, output the executable name, in canonical case.

	* s-tataat.ads (Access_Dummy_Wrapper): Add pragma No_Strict_Aliasing
	to avoid warnings when instantiating Ada.Task_Attributes.
	Minor reformating.

	* mlib-prj.adb (Process_Imported_Libraries): Get the imported libraries
	in the correct order.

	* prj-makr.adb (Process_Directory): No longer use GNAT.Expect, but

	force generation of a freeze node for the inherited operation, so the
	corresponding dispatch entry is properly initialized.
	(Make_Predefined_Primitive_Specs): Check that return type is Boolean
	when looking for user-defined equality operation.

	* exp_ch4.adb (Expand_Composite_Equality): Check that return type is
	boolean when locating primitive equality of tagged component.

	bit-aligned field and the right-hand side a string literal, introduce
	a temporary before expanding assignment into a loop.

	* exp_ch9.adb (Expand_N_Task_Type_Declaration): Copy expression for
	priority in full, to ensure that any expanded subepxressions of it are
	elaborated in the scope of the init_proc.

	* exp_prag.adb (Expand_Pragma_Import): Search for initialization call
	after object declaration, skipping over code that may have been
	generated for validity checks.

	* sem_ch12.adb (Validate_Private_Type_Instance): If type has unknown
	discriminants, ignore the known discriminants of its full view, if
	any, to check legality.

	component if type has unknown discriminants.
	(Analyze_Private_Extension_Declaration): Discriminant constraint is

	* sem_ch6.adb (Analyze_Generic_Subprogram_Body): Generate reference
	for end label when present.

	* s-fileio.adb (Open): When called with a C_Stream, use given name for

	-Dnnn switch given

	* bindusg.adb: Add line for new -D switch

	* exp_aggr.adb (Type_May_Have_Bit_Aligned_Components): More appropriate
	replacement name for Type_May_Have_Non_Bit_Aligned_Components!
	Add circuitry for both records and arrays to avoid gigi
	processing if the type involved has non-bit-aligned components

	* exp_ch5.adb (Expand_Assign_Array): Avoid assumption that
	N_String_Literal node always references an E_String_Literal_Subtype
	entity. This may not be true in the future.
	(Possible_Bit_Aligned_Component): Move processing of
	Component_May_Be_Bit_Aligned from exp_ch5 to exp_util

	* exp_ch6.adb (Expand_Thread_Body): Pick up

	of a file not found, which was an oversight.
	Note if secondary stack unit is used by compiler.

	* sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
	ineffective elaborate all pragmas on non-visible packages (this

	library naming scheme.

	* mlib-prj.adb (Build_Library): Generate different names for the static
	or dynamic version of the GNAT runtime. This is needed to support the
	new shared library naming scheme.
	(Process_Binder_File): Add detection of shared library in binder file
	based on the new naming scheme.

	* gnatlink.adb (Process_Binder_File): Properly detect the new naming
	scheme for the shared runtime libraries.

	* Makefile.in:

	scheme.
	(install-gnatlib): Do not create symlinks for shared libraries.

2004-01-05  Ed Schonberg  <schonberg@gnat.com>

	* sem_ch4.adb (Analyze_Allocator): Check restriction on dynamic
	protected objects when allocator has a subtype indication, not a
	qualified expression. Note that qualified expressions may have to be
	checked when limited aggregates are implemented.

	configurable run-time (e.g. if a library is not needed at all, provide
	a dummy empty library).

	* targparm.ads: Configurable_Run_Time mode no longer affects linker
	options (-L parameters and standard libraries). What we plan to do is

2003-12-08  Javier Miranda  <miranda@gnat.com>

	* exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded

	are not supported. Add new formal to pass the component type (Ctype).
	It is required to call the corresponding IP subprogram in case of
	default initialized components.
	(Gen_Assign): In case of default-initialized component, generate a
	call to the IP subprogram associated with the component.
	(Build_Record_Aggr_Code): Remove the aggregate from the parent in case
	of aggregate with default initialized components.

	all the present expressions.

	* exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
	to indicate that the initialization call corresponds to a
	default-initialized component of an aggregate.
	In case of default initialized aggregate with tasks this parameter is
	used to generate a null string (this is just a workaround that must be
	improved later). In case of discriminants, this parameter is used to
	generate a selected component node that gives access to the discriminant
	value.

	* exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
	subprogram, based on Build_Task_Allocate_Block, but adapted to expand
	allocated aggregates with default-initialized components.

	* par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve error message if
	the box notation is used in positional aggregates.

	Previous_End).

	* prj-part.ads (Parse): New Boolean parameter Store_Comments,
	defaulted to False.

	(Time_Stamp_Mismatch): use CRC_Match for comparison.
	(Set_Source_Table): idem.

	* ali-util.ads:
	(Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
	instead of simple checksum.
	(CRC_Match): new function.
	(CRC_Error): new constant.

	* ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
	a CRC now and not a simple checksum. A CRC uses lower-case hex
	letters, fixes ambiguity in parsing.

	* ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
	is what this variable will store.

	* bcheck.adb: Change reference to chechsum in comments by CRC.
	(Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.

	renaming since now GNAT does not use a simple checksum but a
	CRC using GNAT.CRC32.

	* gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
	now and not anymore a simple checksum.

	* lib-load.adb: Use Source_CRC instead of Source_Checksum in many

	Update comments for the CRC.

	* types.adb (Hex): Use lowercase for the letter part.

	* types.ads (Get_Hex_String): Returns the hexadecimal representation
	for a word. This is currently used only for CRC. In previous version,
	the checksum was using a representation with all letter being
	upper-case. With the new implementation (using CRC) we do not remove
	the 32th bit of the CRC, so we can have an upper-case starting letter
	in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
	It is ambigous since the CRC was optional and could be followed by
	options like EB, EE. So now this routines uses lower-case letter for
	the hexadecimal representation. Strange enough only lower case letters
	where checked in Scan_ALI (even if this was not a possible case).

	* gnatvsn.ads (Library_Version): changed to 3.15a.

	* s-crc32.ads: Initial version from GNAT.CRC32. This is the version
	for the compiler.

	* s-crc32.adb: Initial version from GNAT.CRC32. This is the version
	for the compiler.

	* ali-util.adb: Redo previous change to avoid using word CRC everywhere
	Add 2001 to copyright notice
	(Accumulate_Checksum): Modify to use System.CRC32.

	* ali-util.ads: Redo changes of previous revision to continue to use
	the word Checksum. Add 2001 to copyright notice.

	* ali.adb: Undo some of previous changes, not needed.
	Keep the change for lower case letters in the checksum.

	* ali.ads: Undo previous change not needed.

	* bcheck.adb: Undo most of previous change, not needed.
	But do use Checksums_Match for checksum comparison.

	* gnatls.adb: Undo most of previous change, not needed.
	But do use Checksums_Match for comparing checksums.

	* lib-load.adb: Undo previous change, not needed.

	* lib-writ.adb: Undo previous change, not needed.

	* lib-writ.ads: Document that checksums use lower case,
	not upper case letters.

	* scans.adb: Undo previous change, not needed

	* scans.ads: Undo previous change, not needed.

	* scn-nlit.adb: Undo previous changes, not needed.
