[multiple changes] 

2017-11-08  Yannick Moy  <moy@adacore.com>

	* sem_ch8.adb (Use_One_Type, Update_Use_Clause_Chain): Do not report
	about unused use-type or use-package clauses inside inlined bodies.

2017-11-08  Hristian Kirtchev  <kirtchev@adacore.com>

	* sem_elab.adb (Ensure_Prior_Elaboration): Add new parameter
	In_Partial_Fin along with a comment on its usage. Do not guarantee the
	prior elaboration of a unit when the need came from a partial
	finalization context.
	(In_Initialization_Context): Relocated to Process_Call.
	(Is_Partial_Finalization_Proc): New routine.
	(Process_Access): Add new parameter In_Partial_Fin along with a comment
	on its usage.
	(Process_Activation_Call): Add new parameter In_Partial_Fin along with
	a comment on its usage.
	(Process_Activation_Conditional_ABE_Impl): Add new parameter
	In_Partial_Fin along with a comment on its usage. Do not emit any ABE
	diagnostics when the activation occurs in a partial finalization
	context.
	(Process_Activation_Guaranteed_ABE_Impl): Add new parameter
	In_Partial_Fin along with a comment on its usage.
	(Process_Call): Add new parameter In_Partial_Fin along with a comment
	on its usage. A call is within a partial finalization context when it
	targets a finalizer or primitive [Deep_]Finalize, and the call appears
	in initialization actions. Pass this information down to the recursive
	steps of the Processing phase.
	(Process_Call_Ada): Add new parameter In_Partial_Fin along with a
	comment on its usage. Remove the guard which suppresses the generation
	of implicit Elaborate[_All] pragmas. This is now done in
	Ensure_Prior_Elaboration.
	(Process_Call_Conditional_ABE): Add new parameter In_Partial_Fin along
	with a comment on its usage. Do not emit any ABE diagnostics when the
	call occurs in a partial finalization context.
	(Process_Call_SPARK): Add new parameter In_Partial_Fin along with a
	comment on its usage.
	(Process_Instantiation): Add new parameter In_Partial_Fin along with a
	comment on its usage.
	(Process_Instantiation_Ada): Add new parameter In_Partial_Fin along
	with a comment on its usage.
	(Process_Instantiation_Conditional_ABE): Add new parameter
	In_Partial_Fin along with a comment on its usage. Do not emit any ABE
	diagnostics when the instantiation occurs in a partial finalization
	context.
	(Process_Instantiation_SPARK): Add new parameter In_Partial_Fin along
	with a comment on its usage.
	(Process_Scenario): Add new parameter In_Partial_Fin along  with a
	comment on its usage.
	(Process_Single_Activation): Add new parameter In_Partial_Fin along
	with a comment on its usage.
	(Traverse_Body): Add new parameter In_Partial_Fin along with a comment
	on its usage.

2017-11-08  Arnaud Charlet  <charlet@adacore.com>

	* sem_ch13.adb: Add optional parameter to Error_Msg.

2017-11-08  Jerome Lambourg  <lambourg@adacore.com>

	* fname.adb (Is_Internal_File_Name): Do not check the 8+3 naming schema
	for the Interfaces.* hierarchy as longer unit names are now allowed.

2017-11-08  Arnaud Charlet  <charlet@adacore.com>

	* sem_util.adb (Subprogram_Name): Emit sloc for the enclosing
	subprogram as well.  Support more cases of entities.
	(Append_Entity_Name): Add some defensive code.
