+	redundant local constants.
+
+2022-11-21  Steve Baird  <baird@adacore.com>
+
+	* libgnat/a-sttebu.adb (Put): Add missing call to Encode.

+2022-11-21  Bob Duff  <duff@adacore.com>
+
+	* warnsw.ads, warnsw.adb: Move warning flags here from package
+	Opt. Rename Warning_Record to be Warnings_State. Use an array
+	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.

+	(Adjust_Global_Switches): Expanded names needed.
+	* inline.ads: Rename Warning_Record to be Warnings_State.

+	the locations of some components are left unspecified).
+	* gnat_ugn.texi: Regenerate.
+
+2022-11-21  Marc Poulhiès  <poulhies@adacore.com>

+	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

+	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.

+2022-05-12  Bob Duff  <duff@adacore.com>
+
+	* namet.ads, namet.adb (Write_Name_For_Debug): New more-robust

+	(Destroy_Global_Name_Buffer): New procedure to help detect bugs

+	* 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

+	Note that the call to Get_Name_String was superfluous.
+	(Tree_Dump): Call Write_Unit_Name_For_Debug instead of
