2024-01-09  Eric Botcazou  <ebotcazou@adacore.com>

	TYPE_CANONICAL of types when it comes to aliasing.

2024-01-09  Eric Botcazou  <ebotcazou@adacore.com>

	separate FLD local variable to hold the first field of the fat
	pointer type being built.

	the first two parameters.

2024-01-09  Viljar Indus  <indus@adacore.com>

	* sem_attr.adb: avoid marking a use of the Address attribute

2024-01-09  Gary Dismukes  <dismukes@adacore.com>

	* exp_aggr.adb (Expand_Container_Aggregate): Change "not Present"
	tests to tests using "No" (in two places).

2024-01-09  Gary Dismukes  <dismukes@adacore.com>

	* exp_aggr.adb (Expand_Container_Aggregate): Add code to determine
	whether the aggregate is an indexed aggregate, setting a flag
	(Is_Indexed_Aggregate), which is tested to have proper separation
	of treatment for the Add_Unnamed
	(for positional aggregates) and New_Indexed (for indexed
	aggregates) cases. In the code generating associations for indexed
	aggregates, remove the code for Expressions cases entirely, since
	the code for indexed aggregates is governed by the presence of
	Component_Associations, and add an assertion that Expressions must
	be Empty. Also, exclude empty aggregates from entering that code.

	parameter is from a package that was mentioned in a limited with
	clause, and make no further checks, since this check routine does
	not have all the logic to check such a usage.

2024-01-09  Eric Botcazou  <ebotcazou@adacore.com>

	* freeze.adb (Freeze_Expression.Has_Decl_In_List): Deal specifically
	with itypes that are class-wide subtypes.

	when inlined subprogram is detected to be recursive.

2024-01-09  Piotr Trojanek  <trojanek@adacore.com>

	* inline.adb (Establish_Actual_Mapping_For_Inlined_Call):
	Remove detection of recursive calls.

2024-01-09  Steve Baird  <baird@adacore.com>

	* sem_ch8.adb (Check_Constrained_Object): Before updating the
	subtype mark of an object renaming declaration by calling Rewrite,
	first check whether the destination of the Rewrite call exists.
	* atree.adb (Copy_Slots): Return without performing any updates if
	Destination equals Empty or Error, or if Source equals Empty. Any
	of those conditions indicates an error case.
	* sem_ch12.adb (Analyze_Formal_Derived_Type): Avoid cascading
	errors.

	not pass Error as destination in a call to Rewrite.
