	* exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
	delegate the secondary stack management when there is no suitable

	(Find_Node_To_Be_Wrapped): Renamed to Find_Transient_Context. Update
	the comment on usage.
	(Find_Transient_Context): Change the initinte loop into a while loop.
	Iterations schemes and iterator specifications are not valid transient
	contexts because they rely on special processing. Assignment statements
	are now treated as a normal transient context, special cases are
	handled by the caller. Add special processing for pragma Check.
	(Is_OK_Construct): Removed. Its functionality has been merged in
	routine Find_Transient_Context.
	* sem_ch5.adb (Check_Call): Reimplemented. Add code to properly
	retrieve the subprogram being invoked. Use a more accurate predicate
	(Requires_Transient_Scope) to determine that the function will emply

	* exp_ch7.adb (Establish_Transient_Scope): Restructured. Delegate the
	management of the secondary stack to an enclosing scope if there is no
	suitable construct to wrap, and the transient scope was intended to
	manage the secondary stack.
	(Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative

	warning.

2018-01-11  Javier Miranda  <miranda@adacore.com>

	* exp_util.adb (Remove_Side_Effects): No action done for functions

	(Parent_With): New routine.
	(Set_Implicit_With_From_Instantiation): Removed.
	(Set_Parent_With): New routine.
	* sinfo.ads: Update the documentation of attribute Implicit_With.
	Remove attribute Implicit_With_From_Instantiation along with
	occurrences in nodes.  Add attribute Parent_With along with occurrences
	in nodes.
	(Implicit_With_From_Instantiation): Removed along with pragma Inline.
	(Parent_With): New routine along with pragma Inline.
	(Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.
	(Set_Parent_With): New routine along with pragma Inline.

	* sem_util.adb (Find_Enclosing_Scope): Return the unique defining
	entity when the enclosing construct is a body.

2018-01-11  Patrick Bernardi  <bernardi@adacore.com>

	* exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
	Secondary_Stack_Size handling as a pragma is now generated for the
	corresponding aspect instead of an attribute.  Pragma expression is
	relocated instead of evaluated. Discriminant of the corresponding
	record type is referenced rather than the type discriminant.
	(Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
	Secondary_Stack_Size rep item checks to only look for the pragma rep.
	* sem_ch13.adb (Analyze_One_Aspect): Transform
	Aspect_Secondary_Stack_Size into a pragma instead of an attribute
	because the attribute does not have visibility on a task type's
	discriminants when the type's definition is expanded.
	(Analyze_Attribute_Definition_Clause): Remove handling of
	Attribute_Secondary_Stack_Size.
	* snames.adb-tmpl, snames.ads-tmpl: Remove
	Attribute_Secondary_Stack_Size, no longer used.

	* sem_ch8.adb: Minor comment fix.

2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>

	* exp_ch4.adb (Process_Action): Do not abandon the inspection of an
	individual action because the action may denote a complex expression,
	such as a case statement, which in turn may contain additional
	transient objects.

2018-01-11  Ed Schonberg  <schonberg@adacore.com>

	* sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
	analysis on a copy of the expression with a copy of the index variable,
	because full expansion will rewrite construct into a loop with the
	original loop variable.
	* exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
	expression is an iterated component association. Full analysis takes
	place when construct is rewritten as a loop.
	(In_Place_Assign_OK, Safe_Component): An iterated_component_association
	is not safe for in-place assignment.
	* sem_util.adb (Remove_Entity): Handle properly the case of an isolated
	entity with no homonym and no other entity in the scope.

2018-01-11  Justin Squirek  <squirek@adacore.com>

	* sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
	message to be printed on the pragma argument identifier.

2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>

	* exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
	entity of the generated invariant procedure in order to construct a
	proper entity chain.

2018-01-11  Piotr Trojanek  <trojanek@adacore.com>

	* sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
	comment.

2018-01-11  Arnaud Charlet  <charlet@adacore.com>

	* einfo.ads, einfo.adb (Activation_Record_Component,
	Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
	Allow E_Discriminant.

2018-01-10  Eric Botcazou  <ebotcazou@adacore.com>

	* gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
	for atomic access once the component size is taken into account and
	also do it if the component type is Atomic or Volatile_Full_Access.

2018-01-04  Eric Botcazou  <ebotcazou@adacore.com>

	* gnatvsn.ads: Bump copyright year.
