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

474 2018-08-21 Ed Schonberg <schonberg@adacore.com>
476 * sem_ch6.adb (Check_Synchronized_Overriding): The conformance
477 between an overriding protected operation and the overridden
478 abstract progenitor operation requires subtype conformance;
479 requiring equality of return types in the case of a function is

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

535 one expected (in the statement being analyzed).
536 (Process_Path): Given an operation and a current state, call
537 Perm_Error if there is any mismatch.
538 (Return_Declarations, Return_Globals, Return_The_Global): Check
539 the state of a given name at the end of the subprogram. These
540 procedures may change depending on how we shall finally deal
541 with globals and the rhs state in a move operation.
542 (Set_Perm_Extensions, Set_Perm_Prefixes_Borrow,
543 Set_Perm_Prefixes, Setup_Globals, Setup_Parameter_Or_Global,

884 in an instance, when the generic parameters include an interface type

1051 we continued freezeing entities outside of the subprogram. Now, when
1052 climbing the parents chain to locate the correct placement for the
1053 freezeing node, we check if the entity can be frozen and only when no
1054 enclosing node is marked as Must_Not_Freeze the entity is frozen.

1066 Its code is basically the previous version of this routine but extended
1067 with an additional parameter which is used to specify if during
1068 preanalysis we are allowed to freeze entities. If the new parameter is
1069 True then the subtree root node is marked as Must_Not_Freeze and no
1070 entities are frozen during preanalysis.
1071 (Preanalyze_And_Resolve): Invokes the internal version of
1072 Preanalyze_And_Resolve without entity freezing.
1073 (Preanalyze_With_Freezing_And_Resolve): Invokes the internal version of

1600 * exp_ch6.adb (Add_Unconstrained_Actuals_To_Build_In_Place_Call): Do
1601 not add any actuals when the size of the object is known, and the
1602 caller will allocate it.
1603 (Build_Heap_Allocator): Rename to Build_Heap_Or_Pool_Allocator to
1604 better illustrate its functionality. Update the comment on the
1605 generated code. Generate a branch for the heap and pool cases where
1606 the object is not necessarity controlled.
1607 (Expand_N_Extended_Return_Statement): Expand the extended return
1608 statement into four branches depending the requested mode if the caller
1609 will not allocate the object on its side.
1610 (Make_Build_In_Place_Call_In_Allocator): Do not allocate a controlled
1611 object on the caller side because this will violate the semantics of

1626 unwinding phase during which this subprogram is called. For an Ada
1627 exception, don't update the current exception buffer from the raised

1629 call now issued just before propagation starts.
1630 (Propagate_GCC_Exception): Move call to Setup_Current_Excep ahead of
1631 the unwinding start, conveying Phase 0.
1632 (Unhandled_Except_Handler): Pass UA_CLEANUP_PHASE as the Phase value on
1633 the call to Setup_Current_Excep.

2135 comment about the memset case.
2137 2018-05-30 Bob Duff <duff@adacore.com>
2139 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
2140 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
2141 We need to analyze it as part of analyzing the block, so that if the
2142 call to Element that initializes Elmt_Decl returns on the secondary
2143 stack, the block will ss_mark/ss_release. This block is inside the
2144 loop; we don't want to leak memory until the loop exits. The purpose
2145 of analyzing Elmt_Decl first was to catch the error of modifying it,
2146 which is illegal because it's a loop parameter. The above causes us to
2147 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
2148 it on the Element entity, so we end up with an E_Variable node with the
2150 * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.
2151 * sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop
2152 parameter not allowed" error if Is_Loop_Parameter.
2153 * sem_util.adb (Is_Variable): Return False if Is_Loop_Parameter, to
2154 trigger the call to Diagnose_Non_Variable_Lhs.

2159 * sem_eval.adb (Check_Non_Static_Context, Out_Of_Range): Ignore out of
2160 range values for System.Priority in CodePeer mode since the actual
2161 target compiler may provide a wider range.

2170 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
2171 a package body that is a compilation unit may contain blocks that
2172 declare local subprograms. In Subprogram_Unnesting Mode such
2173 subprograms must be handled as nested inside the (implicit) elaboration
2174 procedure that executes that statement part. To handle properly uplevel
2175 references we construct that subprogram explicitly, to contain blocks
2176 and inner subprograms, The statement part of the compilation unit
2177 becomes a call to this subprogram. This is only done if blocks are
2178 present in the statement list of the body.

2190 for subprogram instantiations to enter callable entity into Subp table.

2249 tagged type. In such case, collecting the list of primitives we may
2250 find two equality primitives: one associated with the untagged private

2513 * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
2514 value when converting a float value to a fixed-point value. This is
2515 required for CCG because it handles fixed-point types by means of
2516 unsigned integer type variables. The range check is now performed using

2555 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
2556 when bounds of fixed type are static, to remove some spuerfluous
2557 implicit conversions and provide an accurate result when converting
2558 back and forth between the fixed point type and a floating point type.

2569 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
2570 constant with private view so we take the address of that entity.
2571 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
2572 any; all callers changed. Handle N_Indexed_Component like
2573 N_Attribute_Reference. Add N_Type_Conversion case.
2574 (Visit_Node): Indexed references can be uplevel if the type isn't
2576 (Unnest_Subprograms): Don't rewrite if no reference given. If call has

2581 * exp_aggr.adb (Flatten): Copy tree of expression in a component
2582 association with a range or a set of discrete choices, rather than

2602 * repinfo.adb (Expr_Value_S): New routine.
2603 (List_Linker_Section): Properly extract the value of the section
2606 2018-05-28 Patrick Bernardi <bernardi@adacore.com>
2608 * doc/gnat_ugn/building_executable_programs_with_gnat.rst: Update the
2609 description of the -D binder switch to reflect current usage.

2637 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
2639 * sem_prag.adb (Process_Atomic_Independent_Shared_Volatile): Include
2640 the declarations of single concurrent types because they fall in the
2641 category of full type and object declarations.

2669 * repinfo.adb (List_Array_Info): Start with an explicit blank line and
2670 end with the linker section, if any.
2671 (List_Entities): Do not output the linker section for record types,
2672 array types and variables.
2673 (Print_Expr): Factor out common processing for unary operators and
2674 special values. Adjust and reorder the various cases.
2675 (List_Object_Info): End with the linker section, if any.
2676 (List_Record_Info): Likewise.
2677 (List_Type_Info): Do not start with a blank line.

2691 2018-05-25 Ed Schonberg <schonberg@adacore.com>
2693 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
2694 of a fixed point type and the parent is a multiplying operation,
2695 resolve the operand with its own type because the context will impose a
2696 resulting type on the result of the multiplication by means of
2697 approriate conversion.
2699 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
2701 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
2702 the in-place initialization aggregate created for pragmas
2703 Initialize_Scalars or Normalize_Scalars is performed with checks
2706 2018-05-25 Arnaud Charlet <charlet@adacore.com>
2708 * exp_aggr.adb (Convert_To_Positional): Bump default for

2730 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
2732 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
2733 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
2734 into three distring cases rather than in one loop which attempts to
2735 handle all three cases. This rewrite eliminates an issue where the last
2736 frame of the stack cannot be freed, thus causing the memory range of a
2737 new frame to approach the overflow point of the memory index type.
2738 Since the overflow is logically treated as a
2739 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
2740 (SS_Allocate_Static): New routine. The routine factorizes the static
2741 secondary stack-related code from the former SS_Allocate.
2743 2018-05-25 Sergey Rybin <rybin@adacore.com>

2750 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
2751 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
2752 is created when the proper body of the stub is analyzed.
2753 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
2754 is the proper body of a subunit, the cloned body must be inserted in
2755 the declarative list that contains the stub.
2757 2018-05-25 Justin Squirek <squirek@adacore.com>
2759 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
2760 generate code for 6.5(8-10) so that we don't get an assertion error
2761 when dealing with an incomplete return type.
2763 2018-05-25 Arnaud Charlet <charlet@adacore.com>
2765 * pprint.adb (Expression_Name): Strip too long expressions to avoid

2792 2018-05-25 Ed Schonberg <schonberg@adacore.com>
2794 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
2795 Validate_Derived_Type_Instance, to verify that all interfaces
2796 implemented by the formal type are also implemented by the actual. The
2797 verification is complicated when an interface of the formal is declared
2798 in a generic unit and the actual is declared in an instance of it.
2799 There is currently no mechanism to relate an interface declared within
2800 a generic to the corresponding interface in an instance, so we must
2801 traverse the list of interfaces of the actual, looking for a name
2802 match, and verifying that that interface is declared in an instance.
2804 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
2806 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra
2807 assertions; replace function versions of Next_Formal/Next_Actual with

2873 in loops at the library level.
2875 2018-05-25 Ed Schonberg <schonberg@adacore.com>
2877 * sem_ch13.adb (Build_Predicate_Functions): The predicate function
2878 declaration is inserted into the tree and analyzed at that point, so
2879 should not be reinserted when the body is constructed. Inside a
2880 generic, ensure that the body is not inserted twice in the tree.

3372 iteration of an Ada2012 loop is performed to determine the type of the

4180 either as an aspect specification or an explicit attribute
4181 specification clause, for the initialized object.

4257 management of the secondary stack to an enclosing scope if there is no
4258 suitable construct to wrap, and the transient scope was intended to
4259 manage the secondary stack.
4260 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
4261 is a valid boundary for a transient expression which comes from the
4262 statements of the alternative, otherwise alternatives cannot be
4263 wrapped. Assignments of controlled objects which have controlled
4264 actions suppressed now stop the traversal as there is no point in
4265 looking for an enclosing construct. Add several N_xxx_Body choices to
4266 the termination conditions for completeness.

4268 and the associated comment on usage.

4273 (Resolve_Actuals): Account for additional cases where finalization
4274 actions are required by utilizing predicate Needs_Finalization rather
4276 (Resolve_Call): Type initialization procedures can now utilize
4277 transient scopes to manage the secondary stack, thus preventing leaks
4278 during initialization. Remove the previous kludgy algorithm which
4279 attempts to manage the secondary stack at the object creation site.

4327 in the generic unless they reference a formal subprogram. Clarify

4408 primitive_wrappers that correspond to explicit operations that override
4409 an interface primitive.
4410 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
4411 operation to which the class-wide expression applies is a protected op.
4412 with a primitive_wrapper, verify that the updated inherited expression
4413 does not contain an internal call to a protected function. This
4414 completes the implementation of AI12-0166.

4441 which marks implicit with clauses as related to an instantiation.
4442 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
4443 (Parent_With): New routine.
4444 (Set_Implicit_With_From_Instantiation): Removed.

4462 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
4463 Secondary_Stack_Size handling as a pragma is now generated for the
4464 corresponding aspect instead of an attribute. Pragma expression is
4465 relocated instead of evaluated. Discriminant of the corresponding
4466 record type is referenced rather than the type discriminant.
4467 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
4468 Secondary_Stack_Size rep item checks to only look for the pragma rep.
4469 * sem_ch13.adb (Analyze_One_Aspect): Transform
4470 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
4471 because the attribute does not have visibility on a task type's

4491 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
4492 analysis on a copy of the expression with a copy of the index variable,
4493 because full expansion will rewrite construct into a loop with the
4494 original loop variable.
4495 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
4496 expression is an iterated component association. Full analysis takes
4497 place when construct is rewritten as a loop.
4498 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
4499 is not safe for in-place assignment.
