	* sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
	formsl type corresponding to the actual fixed point type is private,
	because in this case there can be no suspicious arithmetic operations
	in the generic unless they reference a formal subprogram.  Clarify
	warning.

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

	* exp_util.adb (Remove_Side_Effects): No action done for functions
	returning class-wide types since it requires generating code using
	'reference and the CCG target has no secondary stack.
	* gnat1drv.adb: Disable building static dispatch tables when generating
	C code.

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

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

	* exp_aggr.adb, exp_ch9.adb, exp_util.adb, sem_aggr.adb, sem_ch3.adb,
	sem_res.adb, sem_util.adb: Minor reformatting.

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

	* sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
	has a delayed aspect which must be processed at the point the type is
	frozen. This mimics what is done when the predicate is provided by a
	source aspect.

2018-01-11  Doug Rupp  <rupp@adacore.com>

	* init.c (vxworks): Add macro checks for __aarch64__.

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

	Default_Sec_Stack_Size.
	* libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
	limit check so that the integer index does not overflow. Check the
	dynamic stack allocation does not cause the secondary stack pointer to
	overflow.
	(SS_Info): Align colons.
	(SS_Init): Cover the case when bootstraping with an old compiler that
	does not set Default_SS_Size.

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

	* sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
	legality of an inherited operation that may require overriding, ignore
	primitive_wrappers that correspond to explicit operations that override
	an interface primitive.
	* exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
	operation to which the class-wide expression applies is a protected op.
	with a primitive_wrapper, verify that the updated inherited expression
	does not contain an internal call to a protected function.  This
	completes the implementation of AI12-0166.

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

	* ali.adb: Document the remaining letters available for ALI lines.
	(Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
	* ali.ads: Update type With_Record. Field
	Implicit_With_From_Instantiation is no longer in use. Add field
	Implicit_With.
	* csinfo.adb (CSinfo): Remove the setup for attribute
	Implicit_With_From_Instantiation.
	* lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
	either implicitly or explicitly withed.
	(Is_Implicit_With_Clause): New routine.
	(Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
	confusion with the with clause attribute by the same name.
	(Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
	* rtsfind.adb (Maybe_Add_With): Code cleanup.
	* sem_ch8.adb (Present_System_Aux): Code cleanup.
	* sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
	for a parent unit.
	(Implicit_With_On_Parent): Mark the with clause as generated for a
	parent unit.
	* sem_ch12.adb (Inherit_Context): With clauses inherited by an
	instantiation are no longer marked as Implicit_With_From_Instantiation
	because they are already marked as implicit.
	* sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
	which marks implicit with clauses as related to an instantiation.
	* sinfo.adb (Implicit_With_From_Instantiation): Removed.
	(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.

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

	* 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.

2018-01-03  Richard Sandiford  <richard.sandiford@linaro.org>
	    Alan Hayward  <alan.hayward@arm.com>

	    David Sherwood  <david.sherwood@arm.com>

	* gcc-interface/utils.c (gnat_types_compatible_p): Handle
	polynomial TYPE_VECTOR_SUBPARTS.

	    Alan Hayward  <alan.hayward@arm.com>
	    David Sherwood  <david.sherwood@arm.com>

	* gcc-interface/misc.c (enumerate_modes): Handle polynomial
	GET_MODE_NUNITS.

2018-01-03  Jakub Jelinek  <jakub@redhat.com>
