	constant throughout, remove Ret_Obj_Typ local constant, rename
	Ref_Type into Acc_Typ in a couple of places, remove a useless call
	to Set_Etype, use a consistent checks suppression scheme, adjust

	redundant local constants.

	instead of a record; this simplifies the code. Add renamings of
	all the array components for easy reference outside this package.
	Pass the "Family" to Set_Warning_Switch. Use more table-driven
	code. Misc cleanup and comment fixes.
	* opt.ads: Move warning switches to Warnsw.

	extra formals since they will be added when the call is analyzed.
	(Expand_Call_Helper): Ensure that the called subprogram has all its
	extra formals, enforce assertion checking extra formals on thunks,
	and mark calls from thunks as processed-BIP-calls to avoid adding

	* sem_eval.adb
	(Compile_Time_Known_Value): Improve predicate to avoid assertion

	has an exception handler that returns False when the assertion
	fails.
	* sem_util.adb
	(Needs_Result_Accessibility_Level): Do not return False for dispatching
	operations compiled with Ada_Version < 2012 since they they may be
	overridden by primitives compiled with Ada_Version >= Ada_2012.

2022-11-08  Bob Duff  <duff@adacore.com>

	* warnsw.ads, warnsw.adb, fe.h, err_vars.ads, errout.ads: Move

	* gcc-interface/decl.cc: Use Get_Warn_On_Questionable_Layout

2022-11-07  Bob Duff  <duff@adacore.com>

	* bindgen.adb: fixed the way the device init and final symbols are
	computed, re-using the normal way these symbols would be computed
	with a __device_ prefix. Also fixed the "is null;" procedure on
	the host side which are not Ada 95, replaced with a procedure
	raising an exception as it should never be called. Remove the
	unused function Device_Ada_Final_Link_Name.

2022-11-07  Steve Baird  <baird@adacore.com>

	* opt.ads: Declare new string pointer variable, CUDA_Device_Library_Name.

	character is an "'='; use the remaining characters to initialize
	Opt.CUDA_Device_Library_Name.
	* bindgen.adb: Remove (for now) most support for host-side invocation of
	device-side finalization. Make use of the new CUDA_Device_Library_Name
	in determining the string used to refer (on the host side) to the
	device-side initialization procedure. Declare the placeholder routine
	that is named in the CUDA_Execute pragma (and the CUDA_Register_Function
	call) as an exported null procedure, rather than as an imported procedure.
	It is not clear whether it is really necessary to specify the link-name
	for this should-never-be-called subprogram on the host side, but for now it
	shouldn't hurt to do so.

2022-11-07  Piotr Trojanek  <trojanek@adacore.com>

	(Check_For_Warnings): Remove unnecessary exception handler.
	(Warn_On_Known_Condition): Suppress warning when we detect a True
	or False that has been turned into a more complex expression
	because True is represented as "nonzero". (Note that the complex
	expression will subsequently be constant-folded to a Boolean True
	or False). Also simplify to always print "condition is always ..."
	instead of special-casing object names. The special case was
	unhelpful, and indeed wrong when the expression is a literal.

	* debug.adb: Update comments about "d_c" and "d_d" switches.
	* opt.ads: Declare new Boolean variable,
	Enable_CUDA_Device_Expansion. This complements the existing
	Enable_CUDA_Expansion variable, which is used to enable host-side
	CUDA expansion. The new variable enables device-side CUDA
	expansion. It is currently never set during compilation; it is
	only set via a binder switch.
	* switch-b.adb
	(scan_debug_switches): Add new use of the "-d_d" binder switch.
	The new switch and the variable Opt.Enabled_CUDA_Device_Expansion
	follow the existing pattern of the "-d_c" switch and the variable
	Opt.Enabled_CUDA_Expansion. Flag error if both "-d_c" and "-d_d"
	are specified.

2022-09-12  Eric Botcazou  <ebotcazou@adacore.com>

	* contracts.adb (Build_Subprogram_Contract_Wrapper): Remove useless
	local variable. In the case of a function, replace the extended
	return statement by a block statement declaring a renaming of the
	call to the local subprogram after removing side effects manually.
	(Expand_Subprogram_Contract): Adjust description accordingly.
	* exp_ch6.adb (Expand_Ctrl_Function_Call): Rewrite obsolete
	comment and do not apply the transformation twice.

2022-09-12  Justin Squirek  <squirek@adacore.com>

	* contracts.adb, contracts.ads
	(Analyze_Pragmas_In_Declarations): Added to aid in the new
	expansion model so that pragmas relating to contracts can get
	processed early before the rest of the subprogram containing them.
	(Build_Subprogram_Contract_Wrapper): Created to do the majority of
	expansion for postconditions. It builds a local wrapper with the
	statements and declarations within a given subprogram.
	(Is_Prologue_Renaming): Moved out from Process_Preconditions to be
	used generally within the contracts package.
	(Build_Entry_Contract_Wrapper): Moved from exp_ch7.

	of Postconditions_Proc.
	* exp_ch6.adb
	(Add_Return): Remove special expansion for postconditions.
	(Expand_Call): Modify condition checking for calls to access
	subprogram wrappers to handle new expansion models.
	(Expand_Call_Helper): Remove special expansion for postconditions.

	postconditions.
	(Expand_Simple_Function_Return): Remove special expansion for

	handling of 'Old objects removed.
	* exp_ch9.adb
	(Build_Contract_Wrapper): Renamed and moved to contracts package.
	* exp_prag.adb
	(Expand_Pragma_Contract_Cases): Delay analysis of contracts since
	they now instead get analyzed as part of the wrapper generation
	instead of after analysis of their corresponding subprogram's
	body.
	(Expand_Pragma_Check): Label expanded if-statements which come
	from the expansion of assertion statements as
	Comes_From_Check_Or_Contract.
	* freeze.adb
	(Freeze_Entity): Add special case to avoid freezing when a freeze
	node gets generated as part of the expansion of a postcondition
	check.
	* gen_il-gen-gen_nodes.adb: Add new flag
	Comes_From_Check_Or_Contract.
	* gen_il-fields.ads: Add new field Wrapped_Statements. Add new

	* gen_il-gen-gen_entities.adb: Add new field Wrapped_Statements.
	* ghost.adb
	(Is_OK_Declaration): Replace Name_uPostconditions with
	Name_uWrapped_Statements.
	(Is_OK_Statement): Simplify condition due to the loss of
	Original_Node as a result of the new expansion model of contracts
	and use new flag Comes_From_Check_Or_Contract in its place.
	* inline.adb
	(Declare_Postconditions_Result): Replace Name_uPostconditions with
	Name_uWrapped_Statements.
	(Expand_Inlined_Call): Replace Name_uPostconditions with

	* sem_ch11.adb
	(Analyze_Handled_Statements): Remove check to exclude warnings on
	useless assignments within postcondition procedures since
	postconditions no longer get isolated into separate subprograms.
	* sem_ch6.adb
	(Analyze_Generic_Subprogram_Body): Modify expansion of generic
	subprogram bodies so that contracts (and their associated pragmas)
	get analyzed first.
	(Analyze_Subprogram_Body_Helper): Remove global HSS variable due
	to the HSS of the body potentially changing during the expansion
	of contracts. In cases where it was used instead directly call
	Handled_Statement_Sequence. Modify expansion of subprogram bodies
	so that contracts (and their associated pragmas) get analyzed

	a global one.
	(Move_Pragmas): Use new pragma table instead of an explicit list.
	* sem_elab.adb
	(Is_Postconditions_Proc): Deleted since the new scheme of
	expansion no longer divides postcondition checks to a separate
	subprogram and so cannot be easily identified (similar to
	pre-condition checks).

	(Is_Assertion_Pragma_Target): Remove check for postconditions
	procedure
	(Is_Bridge_Target): Remove check for postconditions procedure.
	(Get_Invocation_Attributes): Remove unneeded local variables and
	check for postconditions procedure.
	(Output_Call): Remove info printing for _Postconditions
	subprograms.
	* sem_prag.adb, sem_prag.ads: Add new Pragma table for pragmas
	significant to subprograms, along with tech-debt comment.
	(Check_Arg_Is_Local_Name): Modified to recognize the new
	_Wrapped_Statements internal subprogram and the new expansion
	model.
	(Relocate_Pragmas_To_Body): Replace Name_uPostconditions with
	Name_uWrapped_Statements.
	* sem_res.adb

	(Accessibility_Level): Verify 'Access is not taken based on a
	component of a function result.
	(Has_Significant_Contracts): Replace Name_uPostconditions with

	subprogram bodies that are not to be unnested.

2022-09-12  Steve Baird  <baird@adacore.com>

	* sem_aggr.adb
	(Resolve_Array_Aggregate): Generate an appropriate error message

	N_Iterated_Element_Association node in a bad context.

2022-09-12  Steve Baird  <baird@adacore.com>

	* sem_ch4.adb
	(Analyze_Selected_Component): Initialize the local variable Comp
	to avoid having CodePeer generate an uninitialized variable
	warning.

2022-09-12  Steve Baird  <baird@adacore.com>

	* sem_ch4.adb
	(Analyze_Selected_Component): Avoid initializing the local
	variable Comp if the variable is not going to be subsequently
	referenced. This is a correctness issue because the call to
	First_Entity can fail.

2022-09-12  Steve Baird  <baird@adacore.com>

	* sem_ch9.adb
	(Satisfies_Lock_Free_Requirements): If Ceiling_Locking locking
	policy has been specified, then either return False (if Lock_Free
	was not explicitly specified) or generate a warning that ceiling
	locking will not be implemented for this protected unit (if
	Lock_Free was explicitly specified). Generate an error message (in
	addition to returning False) if an explicit Lock_Free aspect
	specification is rejected because atomic primitives are not
	supported on the given target.
	* doc/gnat_rm/implementation_defined_pragmas.rst: Clarify that the
	Lock_Free aspect for a protected unit takes precedence over the
	Ceiling_Locking locking policy in the case where both apply.
	* gnat_rm.texi: Regenerate.

2022-09-12  Eric Botcazou  <ebotcazou@adacore.com>

	* exp_ch9.adb (Build_Protected_Spec): Tidy up and propagate the

	* sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not check
	references for subprograms generated for protected subprograms.

2022-09-12  Gary Dismukes  <dismukes@adacore.com>

	* sem_res.adb
	(Resolve_Equality_Op): Add handling for equality ops with

	* sem_util.ads
	(Is_User_Defined_Literal): Update spec comment to indicate
	inclusion of named number cases.
	* sem_util.adb
	(Corresponding_Primitive_Op): Rather than following the chain of
	ancestor subprograms via Alias and Overridden_Operation links, we
	check for matching profiles between primitive subprograms of the
	descendant type and the ancestor subprogram (by calling a new
	nested function Profile_Matches_Ancestor). This prevents the
	compiler from hanging due to circular linkages via those fields
	that can occur between inherited and overriding subprograms
	(which might indicate a latent bug, but one that may be rather
	delicate to resolve).
	(Profile_Matches_Ancestor): New nested subprogram to compare the
	profile of a primitive subprogram with the profile of a candidate
	ancestor subprogram.
	(Is_User_Defined_Literal): Also return True in cases where the
	node N denotes a named number (E_Name_Integer and E_Named_Real).

2022-09-12  Steve Baird  <baird@adacore.com>

	* debug.adb: remove a comment.

2022-09-12  Bob Duff  <duff@adacore.com>

	* checks.adb
	(Selected_Length_Checks): In the message for an aggregate that has
	too few or too many elements, add "!!" to make sure the warning
	gets printed in with'ed units. Note that we have to put "!!"
	before the "??", because Compile_Time_Constraint_Error detects
	warnings by comparing the last character of the message with '?'
	(which is bit dubious, but we're not changing that here).
	(Length_Mismatch_Info_Message): Use Unat for some things that
	can't be negative. Specify Decimal instead of Auto in calls to
	UI_Image.
	* sem_util.adb
	(Compile_Time_Constraint_Error): Minor.
	* uintp.adb
	(Image_Uint): It's always better to initialize objects on their
	declaration.

	* par-tchk.adb, par-util.adb, prep.adb, prepcomp.adb, scng.adb:

	* par-ch8.adb, par-ch9.adb, par-endh.adb, par-sync.adb: Likewise.
	* par.adb
	(Pf_Rec): Remove filler, which was added August 25, 1993 to get
	around a compiler limitation that no longer exists. Minor cleanup.
	Remove useless qualfications.
	* par-ch3.adb: Remove redundant return statements.
	(Component_Scan_Loop): Remove loop name; there are no nested
	loops, so it's unnecessary and possibly misleading, and it causes
	too-long lines.
	* par-ch5.adb: DRY: Remove comments that repeat the comments in
	par.adb.
	(P_Sequence_Of_Statements): It is better to initialize things on
	the declaration. And constants are better than variables.
	(Test_Statement_Required): Remove unnecessary insertion of a null
	statement.
	* par-ch6.adb, par-ch7.adb: DRY: Remove comments that repeat the
	comments in par.adb.

	(Is_Build_In_Place_Function): Return False for entities with
	foreign convention.
	(Make_Build_In_Place_Call_In_Object_Declaration): Occurrences of

	foreign convention.
	(Might_Have_Tasks): Fix check of class-wide limited record types.

	(Needs_BIP_Finalization_Master): Likewise.
	(Needs_BIP_Alloc_Form): Likewise.

	(Extra_Formals_Match_OK): New subprogram.
	* sem_eval.adb
	(Compile_Time_Known_Value): Improve predicate to avoid assertion
	failure; found working on this ticket; this change does not affect
	the behavior of the compiler because this subprogram has an
	exception handler that returns False when the assertion fails.
	* sem_util.adb
	(Needs_Result_Accessibility_Level): Do not return False for
	dispatching operations compiled with Ada_Version < 2012 since they
	they may be overridden by primitives compiled with Ada_Version >=

2022-09-06  Eric Botcazou  <ebotcazou@adacore.com>

	* gcc-interface/decl.cc (gnat_to_gnu_param): Set DECL_ARTIFICIAL.

2022-09-06  Eric Botcazou  <ebotcazou@adacore.com>

	* gcc-interface/trans.cc (At_End_Proc_to_gnu): Use the End_Label of

2022-09-06  Eric Botcazou  <ebotcazou@adacore.com>

	* gcc-interface/trans.cc (gnat_to_gnu) <N_Op_Divide>: Report a

	<N_Op_Shift>: Likewise.
	<N_Op_Mod>: Likewise.
	<N_Op_Rem>: Likewise.
	(convert_with_check): Report a violation of No_Dependence on

	a word and a floating-point type.

2022-09-06  Steve Baird  <baird@adacore.com>

	* sem_ch9.adb
	(Allows_Lock_Free_Implementation): Return False if
	Support_Atomic_Primitives is False.

2022-09-06  Steve Baird  <baird@adacore.com>

	* debug.adb: Remove comment regarding the -gnatd9 switch.
	* doc/gnat_rm/implementation_defined_attributes.rst: Remove all
	mention of the Lock_Free attribute.

	Attribute_Lock_Free enumeration element of the Attribute_Id type.
	* sem_ch9.adb
	(Allows_Lock_Free_Implementation): Remove the Debug_Flag_9 test.
	Return False in the case of a protected function whose result type
	requires use of the secondary stack.
	(Satisfies_Lock_Free_Requirements): This functions checks for
	certain constructs and returns False if one is found. In the case
	of a protected function, there is no need to check to see if the
	protected object is being modified. So it is ok to omit *some*
	checks in the case of a protected function. But other checks which
	are required (e.g., the test for a reference to a variable that is
	not part of the protected object) were being incorrectly omitted.
	This could result in accepting "Lock_Free => True" aspect
	specifications that should be rejected.
	* snames.adb-tmpl: Name_Lock_Free no longer requires special
	treatment in Get_Pragma_Id or Is_Pragma_Name (because it is no
	longer an attribute name).
	* snames.ads-tmpl: Move the declaration of Name_Lock_Free to
	reflect the fact that it is no longer the name of an attribute.
	Delete Attribute_Lock_Free from the Attribute_Id enumeration type.

	* exp_ch3.ads
	(Stream_Operation_OK): Declaration moved from the package body.
	* exp_ch6.adb

	foreign convention.
	(Might_Have_Tasks): Fix check of class-wide limited record types.
	(Needs_BIP_Task_Actuals): Remove assertion to allow calling this
	function in more contexts; in addition it returns False for

	(Needs_BIP_Finalization_Master): Likewise.
	(Needs_BIP_Alloc_Form): Likewise.
	* exp_ch6.ads
	(Stream_Operation_OK): Declaration moved from the package body. In

	* sem_util.adb
	(Needs_Result_Accessibility_Level): Do not return False for

	(Build_Finalizer_Call): Attach the "at end" handler to the parent
	of the HSS node in most cases, so it applies to declarations.

	it. Remove the code that moves declarations. Remove some redundant
	code.
	* exp_ch9.adb
	(Build_Protected_Entry): Copy the At_End_Proc.

	protected version.
	(Expand_N_Conditional_Entry_Call): Use First (Statements(...))

	come from source.
	* libgnarl/s-tpoben.ads
	(Lock_Entries, Lock_Entries_With_Status): Document when these

	when casing on a composite selector.
	* gnat_rm.texi: Regenerate.

2022-09-06  Steve Baird  <baird@adacore.com>

	* sem_case.adb: Define a new Boolean constant,
	Simplified_Composite_Coverage_Rules, initialized to True. Setting
	this constant to True has two effects: 1- Representative value
	sets are not fully initialized - this is done to avoid capacity
	problems, as well as for performance. 2- In
	Check_Case_Pattern_Choices, the only legality check performed is a
	check that a "when others =>" choice is present.

	Validated_View in order to get a scalar (as opposed to private)
	subtype.
	(Attribute_Valid): In determining whether to perform a signed or
	unsigned comparison for a range test, call Validated_View in order
	to get a scalar (as opposed to private) type. Also correct a typo
	which, by itself, is the source of the problem reported for this
	ticket.

2022-09-06  Steve Baird  <baird@adacore.com>

	* sem_ch4.adb
	(Analyze_Selected_Component): Define new Boolean-valued function,
	Constraint_Has_Unprefixed_Discriminant_Reference, which takes a
	subtype that is subject to a discriminant-dependent constraint and
	returns True if any of the constraint values are unprefixed
	discriminant names. Usually, the Etype of a selected component
	node is set to Etype of the component. However, in the case of an
	access-to-array component for which this predicate returns True,
	we instead use the base type of the Etype of the component.
	Normally such problematic discriminant references are addressed by
	calling Build_Actual_Subtype_Of_Component, but that doesn't work
	if Full_Analyze is False.

	* libgnat/a-coinve.adb, libgnat/a-convec.adb
	(Append): If the Append that takes an Element and a Count is
	called with Count = 1, then call the Append that does not take a
	Count parameter; otherwise call the code that handles the general
	case. Move the special case detection/handling code that was
	formerly in that version of Append into the version that does not
	take a Count parameter, so that now both versions get the

	Continue to test that flag as before, but add a test for the

	System.Address.
	(Validate_Storage_Model_Type_Aspect): Return immediately in the
	case where the aspect has no Expression (fully-defaulted native
	memory-model case).  No longer issue an error when Address_Type
	isn't specified, and instead use type System.Address as the
	default address type. When the address type is
	System.Address (whether specified or defaulted), no longer issue

	Expression is present) and simply return. In cases where the
	search is done, but no association that matches Nam is found,

	Empty for all other cases.

	declarative item, and to avoid conflict with the new
	P_Declarative_Items. Add In_Statements.  We keep the old
	error-recovery mechanisms in place when In_Statements is False.
	When True, we don't want to complain about statements, because
	we are parsing a sequence of statements.
	(P_Identifier_Declarations): If In_Statements, and we see what

	P_Sequence_Of_Statements with Done = True, so it can parse the
	statement.

	during analysis, but we need it to be set earlier.
	* exp_ch13.adb (Expand_N_Freeze_Entity): Add wrapper subprogram

2022-06-01  Steve Baird  <baird@adacore.com>

	* exp_ch3.ads: Replace visible Build_Discr_Checking_Funcs (which
	did not need to be visible - it was not referenced outside this
	package) with Build_Or_Copy_Discr_Checking_Funcs.
	* exp_ch3.adb: Refactor existing code into 3 procedures -
	Build_Discr_Checking_Funcs, Copy_Discr_Checking_Funcs, and
	Build_Or_Copy_Discr_Checking_Funcs. This refactoring is intended
	to be semantics-preserving.
	* exp_ch4.adb (Expand_N_Selected_Component): Detect case where a
	call should be generated to the Discriminant_Checking_Func for
	the component in question, but that subprogram does not yet
	exist.
	* sem_ch13.adb (Freeze_Entity_Checks): Immediately before
	calling Build_Predicate_Function, add a call to
	Exp_Ch3.Build_Or_Copy_Discr_Checking_Funcs in order to ensure
	that Discriminant_Checking_Func attributes are already set when
	Build_Predicate_Function is called.
	* sem_ch6.adb (Analyze_Expression_Function): If the expression
	of a static expression function has been transformed into an
	N_Raise_xxx_Error node, then we need to copy the original
	expression in order to check the requirement that the expression
	must be a potentially static expression. We also want to set
	aside a copy the untransformed expression for later use in
	checking calls to the expression function via
	Inline_Static_Function_Call.  So introduce a new function,
	Make_Expr_Copy, for use in these situations.
	* sem_res.adb (Preanalyze_And_Resolve): When analyzing certain
	expressions (e.g., a default parameter expression in a
	subprogram declaration) we want to suppress checks. However, we
	do not want to suppress checks for the expression of an
	expression function.

2022-06-01  Bob Duff  <duff@adacore.com>

	* exp_ch5.adb (Expand_Iterator_Loop_Over_Container): For each
	subprogram found, assert that the variable is Empty, so we can
	detect bugs where we find two or more things with the same name.
	Without this patch, that bug would happen when we add the new
	Next procedure.  For Step, make sure we pick the right one, by
	checking name and number of parameters.  For Get_Element_Access,
	check that we're picking a function.  That's not really
	necessary, because there is no procedure with that name, but it
	seems cleaner this way.
	* rtsfind.ads: Minor comment improvement. It seems kind of odd
	to say "under no circumstances", and then immediately contradict
	that with "The one exception is...".

2022-05-30  Bob Duff  <duff@adacore.com>

	* exp_ch7.adb (Wrap_HSS_In_Block): Do not create a new block in
	the case of function bodies. We include all subprogram bodies,
	because it's harmless for procedures. We cannot easily avoid
	creating this block in ALL cases, because some transformations
	of (e.g.) task bodies end up moving some code such that the
	wrong exception handlers apply to that code.
	(Build_Finalizer_Call): Remove code for creating a new block.
	This was unreachable code, given that Wrap_HSS_In_Block has
	already done that, but with the above change to
	Wrap_HSS_In_Block, this code becomes reachable, and triggers
	essentially the same bug.
	* exp_ch7.ads: Adjust comment.

2022-05-30  Justin Squirek  <squirek@adacore.com>

2022-05-30  Steve Baird  <baird@adacore.com>

	* sem_ch13.adb (Is_Predicate_Static): Do not generate warnings
	about subexpressions of enclosing expressions. Generate warnings
	for predicates that are known to be always true or always false,
	except in the case where the predicate is expressed as a Boolean
	literal. Deal with non-predicate-static expressions that have
	been transformed into predicate-static expressions.  Add missing
	Is_Type_Ref call to N_Membership_Test case.

2022-05-13  Javier Miranda  <miranda@adacore.com>

	* freeze.adb (Check_Inherited_Conditions): Dispatch table
	wrappers must be placed in the list of entities of their scope
	at the same place of their wrapped primitive. This is required
	for private types since these wrappers are built when their full
	tagged type declaration is frozen but they may override a
	primitive defined in the public part of the package (and it is
	important to maintain the wrapper in the list of public entities
	of the package to ensure their correct visibility).

2022-05-13  Johannes Kanig  <kanig@adacore.com>

	* osint.ads, osint.adb (Relocate_Path): If the GNSA_ROOT
	environment variable is set, we use that as the prefix, instead
	of computing the prefix from the executable location.

2022-05-13  Steve Baird  <baird@adacore.com>

	* exp_ch3.ads (Build_Intialization_Call): Add new formal
	parameter, Init_Control_Actual, with default value. Clients

	this 4-valued parameter.  The existing Requires_Late_Init
	function is moved into this new package.
	(Build_Initialization_Call): Add new formal parameter for
	subprogram body, use this new formal parameter in generating an
	init proc call.
	(Build_Record_Init_Proc): Replace Set_Tag Boolean formal
	parameter with 4-valued Init_Control_Formal. Wrap if-statements
	with appropriate conditions around tag initialization, early
	initialization, and late initialization statements.
	* exp_util.adb (Build_Task_Image_Decl): Avoid problem with
	duplicate declarations when an init proc for a type extension
	calls the parent type's init proc twice.

	'Address in a call to an instantiation of the implicit
	subprogram To_Pointer with a class-wide interface type target
	requires adding an implicit type conversion to force
	displacement of the "this" pointer.

2022-05-13  Javier Miranda  <miranda@adacore.com>

	* sem_attr.adb (Resolve_Attribute): Ensure that attribute
	expressions are resolved at this stage; required for preanalyzed
	references to discriminants since their resolution (and
	expansion) will take care of updating their Entity attribute to
	reference their discriminal.

2022-05-13  Justin Squirek  <squirek@adacore.com>

	* sem_util.adb (Wrong_Type): Avoid using the first subtype of

	where Extra_Accessibility_Of_Result should be used versus the
	level of the enclosing subprogram. Use original node to avoid
	checking against expanded code. Disable check generation for
	tagged type case.
	(Is_Formal_Of_Current_Function): Added to encompass a predicate
	used within Check_Return_Construct_Accessibility to test if an
	associated expression is related to a relevant formal.
	* sem_util.adb, sem_util.ads (Enclosing_Subprogram): Modified to
	accept Node_Or_Entity_Id.
	(Innermost_Master_Scope_Depth): Calculate level based on the
	subprogram of a return statement instead of the one returned by
	Current_Subprogram.
	(Needs_Result_Accessibility_Level): Remove
	Disable_Coextension_Cases constant, and disable the tagged type
	case for performance reasons.

2022-05-13  Piotr Trojanek  <trojanek@adacore.com>

2022-05-12  Bob Duff  <duff@adacore.com>

	* namet.ads, namet.adb (Write_Name_For_Debug): Add Quote
	parameter to allow conditional addition of quotes. Note that

	version of Write_Name.
	(Destroy_Global_Name_Buffer): New procedure to help detect bugs
	related to use of Global_Name_Buffer.  Misc cleanup and comment
	improvements. E.g. we don't need to document every detail of
	debugging printouts, especially since they can change.
	* uname.ads, uname.adb (Write_Unit_Name_For_Debug): New
	more-robust version of Write_Unit_Name.
	(Get_Unit_Name_String): Pass buffer in, instead of using the
	global variable. Misc cleanup. Remove the "special fudge", which

	has already been eliminated" seems wrong.
	(Write_Unit_Name): Call the new version of Get_Unit_Name_String.
	* errout.adb (Set_Msg_Insertion_Unit_Name): Call the new version

	Get_Library_Unit_Name_String that avoids usage of the global

	(Set_All_Upper_Case): Remove. There is no need for a wrapper
	here -- code is clearer without it.
	* treepr.adb (Print_Name): Call Write_Name_For_Debug, which
	deals with No_Name (etc), rather than duplicating that here.
	Note that the call to Get_Name_String was superfluous.
	(Tree_Dump): Call Write_Unit_Name_For_Debug instead of
	Write_Unit_Name, which crashes if not Is_Valid_Name.
	* erroutc.ads: Improve comments.
	* erroutc.adb (Set_Msg_Name_Buffer): Call
	Destroy_Global_Name_Buffer to detect potential bugs where it
	incorrectly looks at the global variable.
	* sinput.adb (Write_Location): Call Write_Name_For_Debug instead
	of Write_Name, so it won't blow up on invalid data.
	* sinput.ads: Improve comments; remove some verbosity.

	Image_I.
	* libgnat/s-imagei.adb: Add contracts and ghost code.

	in Build_Actual_Array_Constraint and 1 in
	Build_Actual_Record_Constraint). Instead of unconditionally
	using the passed-in object name as the prefix for the new

2022-01-06  Javier Miranda  <miranda@adacore.com>

	* contracts.adb (Restore_Original_Selected_Component): New
	subprogram that traverses a preanalyzed expression searching for
	dispatching calls to functions whose original node was a
	selected component, and replacing them with their original node.
	This functionality is required because the preanalyis of
	dispatching calls using the Object.Operation notation transforms
	such calls, and we need the original condition to properly
	inherit and extend the condition expression on tagged type
	derivations.  This functionality was previously provided by the
	routine Install_Original_Selected_Component (as part of
	inheriting conditions); now it is performed as part of the
	preanalysis of the condition, thus avoiding repeatedly
	installing and restoring such nodes.
	(Install_Original_Selected_Component): Removed.

2022-01-05  Piotr Trojanek  <trojanek@adacore.com>

	* sem_util.adb (Known_Null): Suspenders: Raise Program_Error if
