+
+2018-05-30  Bob Duff  <duff@adacore.com>
+
+	* exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
+	to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
+	We need to analyze it as part of analyzing the block, so that if the
+	call to Element that initializes Elmt_Decl returns on the secondary
+	stack, the block will ss_mark/ss_release. This block is inside the
+	loop; we don't want to leak memory until the loop exits.  The purpose
+	of analyzing Elmt_Decl first was to catch the error of modifying it,
+	which is illegal because it's a loop parameter. The above causes us to
+	miss that error.  Therefore, we add a flag Is_Loop_Parameter, and set
+	it on the Element entity, so we end up with an E_Variable node with the
+	flag set.
+	* einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.
+	* sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop
+	parameter not allowed" error if Is_Loop_Parameter.

+	a package body that is a compilation unit may contain blocks that
+	declare local subprograms.  In Subprogram_Unnesting Mode such
+	subprograms must be handled as nested inside the (implicit) elaboration
+	procedure that executes that statement part. To handle properly uplevel
+	references we construct that subprogram explicitly, to contain blocks
+	and inner subprograms, The statement part of the compilation unit
+	becomes a call to this subprogram. This is only done if blocks are
+	present in the statement list of the body.

-
-2017-09-08  Hristian Kirtchev  <kirtchev@adacore.com>
-
-	* exp_aggr.adb (Expand_Array_Aggregate): Use New_Copy_Tree instead

-
-	* sem_ch12.adb (Check_Formal_Packages): Do not apply conformance
-	check if the instance is within an enclosing instance body. The
-	formal package was legal in the enclosing generic, and is
-	legal in the enclosing instantiation.  This optimisation may be
-	applicable elsewhere, and it also removes spurious errors that
-	may arise with on-the-fly processing  of instantiations that
-	contain Inline_Always subprograms.

-
-2017-09-08  Yannick Moy  <moy@adacore.com>

-	* exp_ch7.adb (Make_Transient_Block): Transient blocks do not need
-	to manage the secondary stack when an enclosing scope already
-	performs this functionality (aka relaxed management). Switch
-	-gnatd.s may be used to force strict management in which case
-	the block will manage the secondary stack unconditionally. Add

-
-2017-04-27  Ed Schonberg  <schonberg@adacore.com>
-
-	* sem_res.adb (Resolve_Call): Refine further the handling of
-	limited views of return types in function calls. If the function
-	that returns a limited view appears in the current unit,
-	we do not replace its type by the non-limited view because
-	this transformation is performed int the back-end. However,
-	the type of the call itself must be the non-limited view, to
-	prevent spurious resolution errors.

-2017-04-27  Ed Schonberg  <schonberg@adacore.com>
-
-	* einfo,ads, einfo.adb (Class_Wide_Preconds, Class_Wide_Postconds):
-	Removed, proposed implementation using generics for class-wide
-	preconditions proved impractical.
-	(Class_Wide_Clone): New attribute of subprogram. Designates
-	subprogram created for primitive operations with class-wide
-	pre/postconditions that contain calls to other primitives. The
-	clone holds the body of the original primitive, but the
-	pre/postonditions do not apply to it. The original body is
-	rewritten as a wrapper for a call to the clone.
-	(Is_Class_Wide_Clone): New flag to identify a Class_Wide_Clone. If
-	the flag is set, no code for the corresponding pre/postconditions
-	is inserted into its body.

-
-2017-04-25  Bob Duff  <duff@adacore.com>
-
-	* sem_prag.adb (No_Return): Give an error if the pragma applies
-	to a body. Specialize the error for the specless body case,
-	as is done for (e.g.) pragma Convention.
-	* debug.adb: Add switch -gnatd.J to disable the above legality
-	checks. This is mainly for use in our test suite, to avoid
-	rewriting a lot of illegal (but working) code.	It might also
-	be useful to customers. Under this switch, if a pragma No_Return
-	applies to a body, and the procedure raises an exception (as it
-	should), the pragma has no effect. If the procedure does return,
-	execution is erroneous.
-
-2017-04-25  Bob Duff  <duff@adacore.com>
-
-	* exp_ch6.adb (Expand_Actuals): This is the
-	root of the problem. It took N as an 'in out' parameter, and in
-	some cases, rewrote N, but then set N to Original_Node(N). So
-	the node returned in N had no Parent. The caller continued
-	processing of this orphaned node. In some cases that caused a
-	crash (e.g. Remove_Side_Effects climbs up Parents in a loop,
-	and trips over the Empty Parent). The solution is to make N an
-	'in' parameter.  Instead of rewriting it, return the list of
-	post-call actions, so the caller can do the rewriting later,
-	after N has been fully processed.
-	(Expand_Call_Helper): Move most of Expand_Call here. It has
-	too many premature 'return' statements, and we want to do the
-	rewriting on return.
-	(Insert_Post_Call_Actions): New procedure to insert the post-call
-	actions in the appropriate place. In the problematic case,
-	that involves rewriting N as an Expression_With_Actions.
-	(Expand_Call): Call the new procedures Expand_Call_Helper and
-	Insert_Post_Call_Actions.

-
-	* s-fileio.adb (Close): When a temp file is

-	rather than waiting until later.
-	(Temp_File_Record): Add File
-	component, so Close can know which Temp_File_Record corresponds
-	to the file being closed.
-	(Delete): Don't delete temp files,
-	because they are deleted by Close.
-	(Open): Set the File component

-	is redundant, set its Used_Operations to empty. This is only
-	necessary for use clauses that appear in the parent of a generic

-
-	* binde.adb (Elab_New): New elaboration order algorithm
-	that is expected to cause fewer ABE issues. This is a work in
-	progress. The new algorithm is currently disabled, and can be
-	enable by the -dp switch, or by modifying the Do_Old and Do_New
-	etc. flags and rebuilding. Experimental code is included to
-	compare the results of the old and new algorithms.
-	* binde.ads: Use GNAT.Dynamic_Tables instead of Table, so we
-	can have multiple of these tables, so the old and new algorithms
-	can coexist.
-	* bindgen.ads (Gen_Output_File): Pass Elab_Order as an 'in'
-	parameter of type array. This avoids the global variable, and
-	allows bounds checking (which is normally defeated by the tables
-	packages). It also ensures that the Elab_Order is read-only
-	to Bindgen.

-	* debug.adb: Document new -dp switch. Modify doc of old -do
