+2021-09-21  Bob Duff  <duff@adacore.com>

+	* sem_ch13.adb (Stream_Size): Print message about allowed stream

+
+	* uintp.ads, uintp.adb (UI_Is_In_Int_Range): Change the type of

+	(Ubool, Opt_Ubool): New "boolean" subtypes.
+	(UI_Is_In_Int_Range): The parameter should probably be
+	Valid_Uint, but we don't change that for now, because it causes
+	failures in gigi.
+	* sem_util.ads, sem_util.adb (Is_True, Is_False,
+	Static_Boolean): Use Opt_Ubool subtype.  Document the fact that
+	Is_True (No_Uint) = True.  Implement Is_False in terms of
+	Is_True.  We considered changing Static_Boolean to return Uint_1
+	in case of error, but that doesn't fit in well with
+	Static_Integer.
+	(Has_Compatible_Alignment_Internal): Deal with cases where Offs
+	is No_Uint. Change one "and" to "and then" to ensure we don't
+	pass No_Uint to ">", which would violate the new assertions.
+	* exp_util.adb, freeze.adb, sem_ch13.adb: Avoid violating new

+2021-09-21  Bob Duff  <duff@adacore.com>
+
+	* einfo-utils.adb: Add support (currently disabled) for using
+	"initial zero" instead of "Uint_0" to represent "unknown".  Call
+	Known_ functions, instead of evilly duplicating their code
+	inline.
+	* fe.h (No_Uint_To_0): New function to convert No_Uint to
+	Uint_0, in order to preserve existing behavior.
+	(Copy_Esize, Copy_RM_Size): New imports from Einfo.Utils.
+	* cstand.adb: Set size fields of Standard_Debug_Renaming_Type

+	sem_util.adb: Protect calls with Known_..., use Copy_...  Remove
+	assumption that Uint_0 represents "unknown".
+	* types.ads (Nonzero_Int): New subtype.
+	* gcc-interface/decl.c, gcc-interface/trans.c: Protect calls
+	with Known_... and use Copy_...  as appropriate, to avoid
+	blowing up in unknown cases. Similarly, call No_Uint_To_0 to
+	preserve existing behavior.
+
+2021-09-21  Steve Baird  <baird@adacore.com>
+
+	* sem_ch13.adb (Analyze_Aspect_Specifications): Add a new nested
+	function, Directly_Specified, and then use it in the
+	implementation of the required check.
+
+2021-09-21  Steve Baird  <baird@adacore.com>
+
+	* libgnat/a-costso.ads, libgnat/a-costso.adb: A new library
+	unit, Ada.Containers.Stable_Sorting, which exports a pair of
+	generics (one within the other) which are instantiated by each
+	of the 5 doubly-linked list container generics to implement
+	their respective Sort procedures. We use a pair of generics,
+	rather than a single generic, in order to further reduce code
+	duplication. The outer generic takes a formal private Node_Ref
+	type representing a reference to a linked list element. For some
+	instances, the corresponding actual parameter will be an access
+	type; for others, it will be the index type for an array.
+	* Makefile.rtl: Include new Ada.Containers.Stable_Sorting unit.
+	* libgnat/a-cbdlli.adb, libgnat/a-cdlili.adb,
+	libgnat/a-cfdlli.adb, libgnat/a-cidlli.adb, libgnat/a-crdlli.adb
+	(Sort): Replace existing Sort implementation with a call to an
+	instance of
+	Ada.Containers.Stable_Sorting.Doubly_Linked_List_Sort. Declare
+	the (trivial) actual parameters needed to declare that instance.
+	* libgnat/a-cfdlli.ads: Fix a bug encountered during testing in
+	the postcondition for M_Elements_Sorted. With a partial
+	ordering, it is possible for all three of (X < Y), (Y < X),
+	and (X = Y) to be simultaneously false, so that case needs to
+	handled correctly.
+
+2021-09-21  Piotr Trojanek  <trojanek@adacore.com>
+
+	* errout.adb (Error_Msg_Internal): Fix references to Sptr and
+	Optr in comment; fix grammar of "low-level" where it is used as
+	an adjective.
+
+2021-09-21  Piotr Trojanek  <trojanek@adacore.com>
+
+	* errout.adb (Write_Source_Code_Lines): Use Cur_Loc before
+	incrementing it, so that we don't need to decrement it.
+
+2021-09-21  Yannick Moy  <moy@adacore.com>
+
+	* errout.adb (Get_Line_End): Do not allow the result to go past
+	the end of the buffer.
+
+2021-09-21  Ed Schonberg  <schonberg@adacore.com>
+
+	* sem_ch3.adb (Process_Discriminant_Expressions): If the
+	constraint is for a Component_Definition that appears in a
+	Component_Declaration, the entity to be used to create the
+	potentially global symbol is the Defining_Identifier of the
+	Component_Declaration.
+
+2021-09-21  Bob Duff  <duff@adacore.com>
+
+	* libgnat/a-stbufi.ads, libgnat/a-stbufi.adb: Change all
+	occurrences of GNAT.OS_Lib to System.OS_Lib.
