	specifications in the same way as is done for CodePeer and
	SPARK. This avoids an internal compiler error if
	Ancestor_Predicate_Function_Called is True but Result_Expr is
	not an N_And_Then node (and is therefore unsuitable as an
	argument in a call to Left_Opnd).

	Predicate_M references. Add new Boolean parameter for predicate
	functions when needed. Restructure body of generated predicate
	functions to implement required Predicate_Failure behavior and
	to set new Predicate_Expression attribute. Remove special
	treatment of raise expressions within predicate expressions.
	* sem_util.ads (Predicate_Failure_Expression,
	Predicate_Function_Needs_Membership_Parameter): New functions.
	* sem_util.adb (Is_Current_Instance): Fix bugs which caused

	* exp_ch9.adb (Build_Find_Body_Index): Remove IF statement whose

	(since the call to Elsif_Parts will check that Nod is present
	and it is an if-statement).

2022-05-19  Arnaud Charlet  <charlet@adacore.com>

	* gnat1drv.adb, gnatcmd.adb: Remove references to gnatfind/xref.
	* doc/gnat_ugn/building_executable_programs_with_gnat.rst,

	(Resolve_Aggregate): Recognize null array aggregates (using
	Is_Null_Aggregate) and, when one is recognized, resolve
	it (using Resolve_Null_Array_Aggregate).  Avoid calling
	Array_Aggr_Subtype for a null array aggregate; the needed
	subtype is built in Resolve_Null_Array_Aggregate. Do not
	incorrectly flag a null aggregate (after it is transformed by
	expansion) as being both positional and named.
	* sem_attr.adb (Eval_Attribute): Special treatment for null
	array aggregate high bounds to avoid incorrectly flagging
	something like Integer'Pred (Integer'First) as an illegal static
	expression.

	aggregate high bounds to avoid incorrectly flagging something
	like Integer'Pred (Integer'First) as an illegal static

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

	subprogram body, use this new formal parameter in generating an
	init proc call.
	(Build_Record_Init_Proc): Replace Set_Tag Boolean formal

	with appropriate conditions around tag initialization, early

	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

	(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

	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

	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

	(Write_Unit_Name): Call the new version of Get_Unit_Name_String.
	* errout.adb (Set_Msg_Insertion_Unit_Name): Call the new version

	deals with No_Name (etc), rather than duplicating that here.
	Note that the call to Get_Name_String was superfluous.

	Write_Unit_Name, which crashes if not Is_Valid_Name.

	Destroy_Global_Name_Buffer to detect potential bugs where it
	incorrectly looks at the global variable.

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

	* 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.

2022-01-05  Steve Baird  <baird@adacore.com>

	* exp_ch5.adb (Finish_Binding_Object_Declaration): Fix a bug
	that was introduced in the previous commit.  The previous
	version initialized a Boolean constant Declare_Copy before the
	variable Decl had been initialized properly.

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

	* sem_prag.adb (Adjust_External_Name_Case): Use membership test.

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

	* targparm.adb (Get_Target_Parameters): Likewise.

2022-01-05  Bob Duff  <duff@adacore.com>

	* repinfo.adb (List_Entities): The code was assuming that if we
	encounter a package in the current scope, then it must be
	a (physically) nested package.  That was wrong, because it could
	be a child package.  Avoid recursing into child packages; they
	have not been annotated with representation information, and
	-gnatR2 queries that information.

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

	* exp_attr.adb (Build_Array_VS_Func): Remove explicit "IN" in
	spec of the generated array validation function; it was
	redundant, just like it would be in a user-written code.

2022-01-05  Bob Duff  <duff@adacore.com>

	postcondition that Val /= Var.
	* sem_util.adb (Known_Null): Suspenders: Raise Program_Error if
	Get_Current_Value_Condition returned the same value. This will
	be enabled even without assertions, because infinite recursion
	is a nuisance -- better to crash if this bug ever occurs.

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

	* exp_ch3.adb (Make_Null_Procedure_Specs): Simplify by reusing
	Copy_Subprogram_Spec.
