either as an aspect specification or an explicit attribute
specification clause, for the initialized object.
* freeze.adb (Check_Address_Clause): Do not remove side-effects from
initial expressions in the case of a build-in-place call.
2018-01-11 Piotr Trojanek <trojanek@adacore.com>
* sem_eval.adb (Is_Null_Range): Retrieve the full view when called on a
private (sub)type; refactor to avoid early return statement.
(Not_Null_Range): Same as above.
2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
* freeze.adb (Freeze_Entity): Ensure that a Ghost type is not
concurrent, nor effectively volatile.
* ghost.adb (Check_Ghost_Type): New routine.

comment on usage.
(Is_Declaration_Other_Than_Renaming): Removed.
2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
* sem_ch5.adb (Analyze_Assignment): Assignments to variables that act
as Part_Of consituents of single protected types are illegal when they
take place inside a protected function.
(Diagnose_Non_Variable_Lhs): Use Within_Function to check for an
enclosing function.
(Is_Protected_Part_Of_Constituent): New routine.

2018-01-11 Arnaud Charlet <charlet@adacore.com>
Bump copyright notices to 2018.

* binde.adb, par-ch6.adb, par-ch9.adb, sem_ch12.adb, sem_ch13.adb:
Minor reformatting.

to make sure a given expression function is properly parenthesized.

categorization of a subprogram body which does not complete a previous
declaration.

Establish_Transient_Scope.
(Make_Build_In_Place_Call_In_Object_Declaration): Update the call to
Establish_Transient_Scope.

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
is a valid boundary for a transient expression which comes from the
statements of the alternative, otherwise alternatives cannot be
wrapped. Assignments of controlled objects which have controlled
actions suppressed now stop the traversal as there is no point in
looking for an enclosing construct. Add several N_xxx_Body choices to
the termination conditions for completeness.

and the associated comment on usage.

actions are required by utilizing predicate Needs_Finalization rather
than Is_Controlled.

transient scopes to manage the secondary stack, thus preventing leaks
during initialization. Remove the previous kludgy algorithm which
attempts to manage the secondary stack at the object creation site.

* 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>
* libgnat/a-direio.ads, libgnat/a-sequio.ads, libgnat/a-ststio.ads,
libgnat/a-textio.ads, libgnat/a-witeio.ads, libgnat/a-ztexio.ads

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>

limit check so that the integer index does not overflow. Check the
dynamic stack allocation does not cause the secondary stack pointer to
overflow.

does not set Default_SS_Size.

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.

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.

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.

* 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.

entity of the generated invariant procedure in order to construct a
proper entity chain.

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

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