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.

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

	* sem_ch13.adb (Build_Predicate_Functions): If a semantic error
	has been detected then ignore Predicate_Failure aspect
	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

	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

	condition was true-by-construction; remove excessive assertion
	(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.

	it (using Resolve_Null_Array_Aggregate).  Avoid calling

	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

	whether an expression occurs in a class-wide pre/post-condition,
	also check for the possibility that it occurs in a class-wide
	preconditions subprogram that was introduced as part of
	expansion. Without this fix, some legal calls occuring in
	class-wide preconditions may be incorrectly flagged as violating
	the "a call to an abstract subprogram must be dispatching" rule.

	the call to the parent type's finalization procedure. Modify
	nested function Process_Component_List_For_Finalize to set this
	variable (and avoid setting it during a recursive call).  If
	Last_POC_Call is empty, then insert the parent finalization call
	before, rather than after, the finalization code for the

	important to maintain the wrapper in the list of public entities
	of the package to ensure their correct visibility).

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

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

	* namet.ads, namet.adb (Write_Name_For_Debug): New more-robust
	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
	is apparently not needed, and anyway the comment "the %s or %b
	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
	of Get_Unit_Name_String. We pass the global variable here,
	because it's too much trouble to disentangle such uses in
	Errout.
	* sem_util.ads, sem_util.adb, sem_dist.adb
	(Get_Library_Unit_Name): New version of
	Get_Library_Unit_Name_String that avoids usage of the global
	variable.
	* casing.ads, casing.adb, exp_prag.adb, exp_util.adb
	(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.

	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
	selected component node, this new function checks to see if
	perhaps a prefix of that name should be used instead.

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.
