467 Refine the handling of freezing types for expression functions
468 that are not completions, when analyzing the generated body for
469 the function: the body is inserted at the end of the enclosing

471 the same scope that have not been frozen yet.
473 2018-08-21 Ed Schonberg <schonberg@adacore.com>
475 * sem_ch6.adb: Remove Freeze_Expr_Types.

497 2018-08-21 Ed Schonberg <schonberg@adacore.com>
499 * sem_ch6.adb (Check_Synchronized_Overriding): The conformance
500 between an overriding protected operation and the overridden
501 abstract progenitor operation requires subtype conformance;
502 requiring equality of return types in the case of a function is

532 (Check_Declaration): Consider both deep (including elementary
533 access) object declarations and normal variables. First check
534 whether the deep object is of Ownership Aspec True or not, then,
535 depending on its initialization, assign the appropriate state.

1627 better illustrate its functionality. Update the comment on the
1628 generated code. Generate a branch for the heap and pool cases where
1629 the object is not necessarity controlled.

2162 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
2163 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
2164 We need to analyze it as part of analyzing the block, so that if the
2165 call to Element that initializes Elmt_Decl returns on the secondary
2166 stack, the block will ss_mark/ss_release. This block is inside the
2167 loop; we don't want to leak memory until the loop exits. The purpose
2168 of analyzing Elmt_Decl first was to catch the error of modifying it,
2169 which is illegal because it's a loop parameter. The above causes us to
2170 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
2171 it on the Element entity, so we end up with an E_Variable node with the

2194 a package body that is a compilation unit may contain blocks that
2195 declare local subprograms. In Subprogram_Unnesting Mode such
2196 subprograms must be handled as nested inside the (implicit) elaboration
2197 procedure that executes that statement part. To handle properly uplevel
2198 references we construct that subprogram explicitly, to contain blocks
2199 and inner subprograms, The statement part of the compilation unit
2200 becomes a call to this subprogram. This is only done if blocks are

2599 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
2600 been relocated, set first_named pointer in original node as well.

2604 * exp_aggr.adb (Flatten): Copy tree of expression in a component
2605 association with a range or a set of discrete choices, rather than

2621 unnecessary use of 'Unrestricted_Access.
2623 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
2625 * repinfo.adb (Expr_Value_S): New routine.
2626 (List_Linker_Section): Properly extract the value of the section
2629 2018-05-28 Patrick Bernardi <bernardi@adacore.com>
2631 * doc/gnat_ugn/building_executable_programs_with_gnat.rst: Update the
2632 description of the -D binder switch to reflect current usage.

2660 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
2662 * sem_prag.adb (Process_Atomic_Independent_Shared_Volatile): Include
2663 the declarations of single concurrent types because they fall in the
2664 category of full type and object declarations.
2666 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>

2673 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
2674 includes a call to function to which it applies. This may mean an
2675 omission of an attribute reference 'Result, in particular if the
2676 function is pqrameterless.
2678 2018-05-28 Justin Squirek <squirek@adacore.com>

2692 * repinfo.adb (List_Array_Info): Start with an explicit blank line and
2693 end with the linker section, if any.
2694 (List_Entities): Do not output the linker section for record types,
2695 array types and variables.
2696 (Print_Expr): Factor out common processing for unary operators and
2697 special values. Adjust and reorder the various cases.
2698 (List_Object_Info): End with the linker section, if any.
2699 (List_Record_Info): Likewise.
2700 (List_Type_Info): Do not start with a blank line.
2702 2018-05-25 Nicolas Roche <roche@adacore.com>

2705 that the result will be either -infinite or +infinite.

2714 2018-05-25 Ed Schonberg <schonberg@adacore.com>
2716 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
2717 of a fixed point type and the parent is a multiplying operation,
2718 resolve the operand with its own type because the context will impose a
2719 resulting type on the result of the multiplication by means of
2720 approriate conversion.
2722 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
2724 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
2725 the in-place initialization aggregate created for pragmas
2726 Initialize_Scalars or Normalize_Scalars is performed with checks
2729 2018-05-25 Arnaud Charlet <charlet@adacore.com>
2731 * exp_aggr.adb (Convert_To_Positional): Bump default for
2732 Max_Others_Replicate to 32. Update comments.

2753 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
2755 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
2756 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
2757 into three distring cases rather than in one loop which attempts to
2758 handle all three cases. This rewrite eliminates an issue where the last
2759 frame of the stack cannot be freed, thus causing the memory range of a
2760 new frame to approach the overflow point of the memory index type.
2761 Since the overflow is logically treated as a
2762 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
2763 (SS_Allocate_Static): New routine. The routine factorizes the static
2764 secondary stack-related code from the former SS_Allocate.
2766 2018-05-25 Sergey Rybin <rybin@adacore.com>

2773 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
2774 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
2775 is created when the proper body of the stub is analyzed.
2776 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
2777 is the proper body of a subunit, the cloned body must be inserted in
2778 the declarative list that contains the stub.
2780 2018-05-25 Justin Squirek <squirek@adacore.com>
2782 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
2783 generate code for 6.5(8-10) so that we don't get an assertion error
2784 when dealing with an incomplete return type.
2786 2018-05-25 Arnaud Charlet <charlet@adacore.com>
2788 * pprint.adb (Expression_Name): Strip too long expressions to avoid

2815 2018-05-25 Ed Schonberg <schonberg@adacore.com>
2817 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
2818 Validate_Derived_Type_Instance, to verify that all interfaces
2819 implemented by the formal type are also implemented by the actual. The
2820 verification is complicated when an interface of the formal is declared
2821 in a generic unit and the actual is declared in an instance of it.
2822 There is currently no mechanism to relate an interface declared within
2823 a generic to the corresponding interface in an instance, so we must
2824 traverse the list of interfaces of the actual, looking for a name
2825 match, and verifying that that interface is declared in an instance.
2827 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
2829 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra
2830 assertions; replace function versions of Next_Formal/Next_Actual with

2896 in loops at the library level.
2898 2018-05-25 Ed Schonberg <schonberg@adacore.com>
2900 * sem_ch13.adb (Build_Predicate_Functions): The predicate function
2901 declaration is inserted into the tree and analyzed at that point, so
2902 should not be reinserted when the body is constructed. Inside a
2903 generic, ensure that the body is not inserted twice in the tree.

3395 iteration of an Ada2012 loop is performed to determine the type of the
3396 domain, but full analysis is performed once the loop is rewritten as a

4281 suitable construct to wrap, and the transient scope was intended to
4282 manage the secondary stack.
4283 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
4284 is a valid boundary for a transient expression which comes from the
4285 statements of the alternative, otherwise alternatives cannot be
4286 wrapped. Assignments of controlled objects which have controlled
4287 actions suppressed now stop the traversal as there is no point in

4296 (Resolve_Actuals): Account for additional cases where finalization
4297 actions are required by utilizing predicate Needs_Finalization rather
4299 (Resolve_Call): Type initialization procedures can now utilize
4300 transient scopes to manage the secondary stack, thus preventing leaks
4301 during initialization. Remove the previous kludgy algorithm which
4302 attempts to manage the secondary stack at the object creation site.

4431 primitive_wrappers that correspond to explicit operations that override
4432 an interface primitive.
4433 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
4434 operation to which the class-wide expression applies is a protected op.
4435 with a primitive_wrapper, verify that the updated inherited expression
4436 does not contain an internal call to a protected function. This
4437 completes the implementation of AI12-0166.

4449 either implicitly or explicitly withed.
4450 (Is_Implicit_With_Clause): New routine.
4451 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
4452 confusion with the with clause attribute by the same name.

4464 which marks implicit with clauses as related to an instantiation.
4465 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
4466 (Parent_With): New routine.
4467 (Set_Implicit_With_From_Instantiation): Removed.

4485 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
4486 Secondary_Stack_Size handling as a pragma is now generated for the
4487 corresponding aspect instead of an attribute. Pragma expression is
4488 relocated instead of evaluated. Discriminant of the corresponding
4489 record type is referenced rather than the type discriminant.
4490 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
4491 Secondary_Stack_Size rep item checks to only look for the pragma rep.
4492 * sem_ch13.adb (Analyze_One_Aspect): Transform
4493 Aspect_Secondary_Stack_Size into a pragma instead of an attribute

4514 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
4515 analysis on a copy of the expression with a copy of the index variable,
4516 because full expansion will rewrite construct into a loop with the
4517 original loop variable.
4518 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
4519 expression is an iterated component association. Full analysis takes
4520 place when construct is rewritten as a loop.
4521 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
4522 is not safe for in-place assignment.
