 147         * exp_ch7.adb (Establish_Transient_Scope): Restructured. Delegate the
 148         management of the secondary stack to an enclosing scope if there is no
 149         suitable construct to wrap, and the transient scope was intended to
 150         manage the secondary stack.
 151         (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
 152         is a valid boundary for a transient expression which comes from the
 153         statements of the alternative, otherwise alternatives cannot be
 154         wrapped. Assignments of controlled objects which have controlled
 155         actions suppressed now stop the traversal as there is no point in
 156         looking for an enclosing construct. Add several N_xxx_Body choices to
 157         the termination conditions for completeness.
 158         * exp_ch7.ads (Establish_Transient_Scope): Update the parameter profile
 159         and the associated comment on usage.

 161         Establish_Transient_Scope.
 162         (Add_Write_After): Update the call to Establish_Transient_Scope.
 163         * sem_res.adb (Check_Initialization_Call): Removed.
 164         (Resolve_Actuals): Account for additional cases where finalization
 165         actions are required by utilizing predicate Needs_Finalization rather
 166         than Is_Controlled.
 167         (Resolve_Call): Type initialization procedures can now utilize
 168         transient scopes to manage the secondary stack, thus preventing leaks
 169         during initialization.  Remove the previous kludgy algorithm which
 170         attempts to manage the secondary stack at the object creation site.

 216         formsl type corresponding to the actual fixed point type is private,
 217         because in this case there can be no suspicious arithmetic operations
 218         in the generic unless they reference a formal subprogram.  Clarify

 287         * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
 288         limit check so that the integer index does not overflow. Check the

 298         legality of an inherited operation that may require overriding, ignore
 299         primitive_wrappers that correspond to explicit operations that override
 300         an interface primitive.

 319         (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid

 329         instantiation are no longer marked as Implicit_With_From_Instantiation

 352
 353         * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
 354         Secondary_Stack_Size handling as a pragma is now generated for the
 355         corresponding aspect instead of an attribute.  Pragma expression is
 356         relocated instead of evaluated. Discriminant of the corresponding
 357         record type is referenced rather than the type discriminant.
 358         (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
 359         Secondary_Stack_Size rep item checks to only look for the pragma rep.
 360         * sem_ch13.adb (Analyze_One_Aspect): Transform
 361         Aspect_Secondary_Stack_Size into a pragma instead of an attribute
 362         because the attribute does not have visibility on a task type's
 363         discriminants when the type's definition is expanded.
 364         (Analyze_Attribute_Definition_Clause): Remove handling of
 365         Attribute_Secondary_Stack_Size.
 366         * snames.adb-tmpl, snames.ads-tmpl: Remove
 367         Attribute_Secondary_Stack_Size, no longer used.

 371         * sem_ch8.adb: Minor comment fix.

 373 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
 374
 375         * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
 376         individual action because the action may denote a complex expression,
 377         such as a case statement, which in turn may contain additional
 378         transient objects.

 381
 382         * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
 383         analysis on a copy of the expression with a copy of the index variable,
 384         because full expansion will rewrite construct into a loop with the
 385         original loop variable.
 386         * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
 387         expression is an iterated component association. Full analysis takes
 388         place when construct is rewritten as a loop.
 389         (In_Place_Assign_OK, Safe_Component): An iterated_component_association
 390         is not safe for in-place assignment.
 391         * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
 392         entity with no homonym and no other entity in the scope.
 393

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

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

 417
 418         * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
 419         for atomic access once the component size is taken into account and
 420         also do it if the component type is Atomic or Volatile_Full_Access.
 421
