822 Refine the handling of freezing types for expression functions
823 that are not completions, when analyzing the generated body for

826 the same scope that have not been frozen yet.
828 2018-08-21 Ed Schonberg <schonberg@adacore.com>
830 * sem_ch6.adb: Remove Freeze_Expr_Types.

852 2018-08-21 Ed Schonberg <schonberg@adacore.com>
854 * sem_ch6.adb (Check_Synchronized_Overriding): The conformance
855 between an overriding protected operation and the overridden
856 abstract progenitor operation requires subtype conformance;
857 requiring equality of return types in the case of a function is
858 too restrictive and leads to spurious errors when the return
859 type is a generic actual.

885 parameters depending on their modes then analyse the body
887 (Check_Declaration): Consider both deep (including elementary
888 access) object declarations and normal variables. First check
889 whether the deep object is of Ownership Aspec True or not, then,
890 depending on its initialization, assign the appropriate state.
891 Check related to non access type variables deal with
892 initialization value permissions.

913 one expected (in the statement being analyzed).
914 (Process_Path): Given an operation and a current state, call
915 Perm_Error if there is any mismatch.
916 (Return_Declarations, Return_Globals, Return_The_Global): Check
917 the state of a given name at the end of the subprogram. These
918 procedures may change depending on how we shall finally deal
919 with globals and the rhs state in a move operation.
920 (Set_Perm_Extensions, Set_Perm_Prefixes_Borrow,
921 Set_Perm_Prefixes, Setup_Globals, Setup_Parameter_Or_Global,
922 Setup_Parameters): Set up the new states to the given node and
923 up and down the tree after an operation.

1427 outside of a subprogram body. This case was previously handled during

1429 we continued freezeing entities outside of the subprogram. Now, when
1430 climbing the parents chain to locate the correct placement for the
1431 freezeing node, we check if the entity can be frozen and only when no
1432 enclosing node is marked as Must_Not_Freeze the entity is frozen.

1444 Its code is basically the previous version of this routine but extended
1445 with an additional parameter which is used to specify if during
1446 preanalysis we are allowed to freeze entities. If the new parameter is
1447 True then the subtree root node is marked as Must_Not_Freeze and no
1448 entities are frozen during preanalysis.
1449 (Preanalyze_And_Resolve): Invokes the internal version of
1450 Preanalyze_And_Resolve without entity freezing.

2372 * exp_ch4.adb (Expand_Modular_Addition, Expand_Modular_Subtraction):
2373 Convert all operands of the generated code to Standard.Unsigned, to
2374 prevent spurious visibility errors. This is needed when the generated

2439 (Start_Search): Modify to use Start_Search_Internal
2440 (Start_Search_Internal): Add to break out an extra flag for searching

2513 comment about the memset case.
2515 2018-05-30 Bob Duff <duff@adacore.com>
2517 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
2518 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
2519 We need to analyze it as part of analyzing the block, so that if the
2520 call to Element that initializes Elmt_Decl returns on the secondary
2521 stack, the block will ss_mark/ss_release. This block is inside the
2522 loop; we don't want to leak memory until the loop exits. The purpose
2523 of analyzing Elmt_Decl first was to catch the error of modifying it,
2524 which is illegal because it's a loop parameter. The above causes us to
2525 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
2526 it on the Element entity, so we end up with an E_Variable node with the
2528 * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.
2529 * sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop
2530 parameter not allowed" error if Is_Loop_Parameter.
2531 * sem_util.adb (Is_Variable): Return False if Is_Loop_Parameter, to

2537 * sem_eval.adb (Check_Non_Static_Context, Out_Of_Range): Ignore out of

2539 target compiler may provide a wider range.

2543 * exp_unst.adb: Search specification of main unit as well, for
2546 2018-05-30 Ed Schonberg <schonberg@adacore.com>
2548 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
2549 a package body that is a compilation unit may contain blocks that
2550 declare local subprograms. In Subprogram_Unnesting Mode such
2551 subprograms must be handled as nested inside the (implicit) elaboration
2552 procedure that executes that statement part. To handle properly uplevel
2553 references we construct that subprogram explicitly, to contain blocks
2554 and inner subprograms, The statement part of the compilation unit
2555 becomes a call to this subprogram. This is only done if blocks are
2556 present in the statement list of the body.
2558 2018-05-30 Bob Duff <duff@adacore.com>

2568 for subprogram instantiations to enter callable entity into Subp table.

2622 private whose full view is a tagged type.
2623 * sem_util.ads, sem_util.adb (Inherits_From_Tagged_Full_View): New
2625 (Collect_Primitive_Operations): Handle untagged private types completed
2626 with a derivation of an untagged private type whose full view is a
2627 tagged type. In such case, collecting the list of primitives we may
2628 find two equality primitives: one associated with the untagged private
2629 and another associated with the ultimate tagged type (and we must
2630 remove from the returned list this latter one).

2643 * exp_ch6.adb (Expand_N_Subprogram_Body): Do not generate push/pop for
2644 exceptions if subprogram unnesting is in effect, because these branch
2645 nodes are relevant only in the presence of nested subprograms.

2668 child units, both in the specification and possibly in an end label for
2669 the unit, and they do not contain any relevant uplevel references.

2862 * exp_unst.adb (Visit_Node): For indexed components and attribute
2863 references, examine index expressions or associated expressions as well
2864 to record uplevel references.
2865 (Vist_Node): For function and procedure calls, if a formal is an
2866 unconstrained array and the actual is constrained, check whether bounds
2867 of actual have uplevel references.
2869 2018-05-28 Ed Schonberg <schonberg@adacore.com>
2871 * einfo.ads, einfo.adb: Exceptions can be uplevel references, and thus

2882 2018-05-28 Ed Schonberg <schonberg@adacore.com>
2884 * exp_unst.adb (Check_Static_Type): For a record subtype, check
2885 discriminant constraints as well.
2886 (Visit_Node): For a selected component, check type of prefix, as is
2887 done for indexed components and slices.
2889 2018-05-28 Javier Miranda <miranda@adacore.com>
2891 * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
2892 value when converting a float value to a fixed-point value. This is
2893 required for CCG because it handles fixed-point types by means of
2894 unsigned integer type variables. The range check is now performed using
2895 the integer value stored in this temporary.
2897 2018-05-28 Yannick Moy <moy@adacore.com>
2899 * sem_util.adb (Is_OK_Volatile_Context): Add attributes First, Last and

2919 * exp_ch4.adb (Expand_Composite_Equality): For a composite (or FP)
2920 component type, do not expand array equality using the unconstrained
2921 base type, except for the case where the bounds of the type depend on a
2924 2018-05-28 Ed Schonberg <schonberg@adacore.com>
2926 * einfo.ads, einfo.adb (Needs_Activation_Record): New flag on
2927 access-to-subprogram types, to indicate that an indirect call through
2928 such a type requires an activation record when compiling for LLVM.
2929 * sem_ch3.adb (Access_Subprogram_Declaration): Set new flag as needed.
2931 2018-05-28 Ed Schonberg <schonberg@adacore.com>
2933 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
2934 when bounds of fixed type are static, to remove some spuerfluous
2935 implicit conversions and provide an accurate result when converting
2936 back and forth between the fixed point type and a floating point type.
2938 2018-05-28 Ed Schonberg <schonberg@adacore.com>
2940 * exp_unst.adb (Unnest_Subprogram): Prevent creation of empty
2943 2018-05-28 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
2945 * exp_unst.adb (Check_Static_Type): Add argument to indicate node to be
2946 replaced, if any; all callers changed.
2947 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
2948 constant with private view so we take the address of that entity.
2949 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
2950 any; all callers changed. Handle N_Indexed_Component like
2951 N_Attribute_Reference. Add N_Type_Conversion case.
2952 (Visit_Node): Indexed references can be uplevel if the type isn't
2954 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
2955 been relocated, set first_named pointer in original node as well.
2957 2018-05-28 Ed Schonberg <schonberg@adacore.com>
2959 * exp_aggr.adb (Flatten): Copy tree of expression in a component
2960 association with a range or a set of discrete choices, rather than
2961 relocating the node. This avoids inconsistencies in the tree when
2962 handling nested subprograms with uplevel references for LLVM.

3017 * sem_prag.adb (Process_Atomic_Independent_Shared_Volatile): Include
3018 the declarations of single concurrent types because they fall in the
3019 category of full type and object declarations.

3026 2018-05-28 Ed Schonberg <schonberg@adacore.com>
3028 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
3029 includes a call to function to which it applies. This may mean an
3030 omission of an attribute reference 'Result, in particular if the
3031 function is pqrameterless.
3033 2018-05-28 Justin Squirek <squirek@adacore.com>

3040 * sem_res.adb (Resolve_Range): Re-resolve the low bound of a range in
3041 GNATprove mode, as the order of resolution (low then high) means that

3048 end with the linker section, if any.
3049 (List_Entities): Do not output the linker section for record types,
3050 array types and variables.
3051 (Print_Expr): Factor out common processing for unary operators and
3052 special values. Adjust and reorder the various cases.
3053 (List_Object_Info): End with the linker section, if any.
3054 (List_Record_Info): Likewise.
3055 (List_Type_Info): Do not start with a blank line.
3057 2018-05-25 Nicolas Roche <roche@adacore.com>
3059 * libgnat/s-valrea.adb (Scan_Real): Abort computation once it is sure
3060 that the result will be either -infinite or +infinite.
3062 2018-05-25 Patrick Bernardi <bernardi@adacore.com>
3064 * libgnat/s-parame.ads, libgnat/s-parame__vxworks.ads,

3066 Expand range of type to match the address space of the target.
3067 (Task_Storage_Size): Remove unused type.
3069 2018-05-25 Ed Schonberg <schonberg@adacore.com>
3071 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
3072 of a fixed point type and the parent is a multiplying operation,
3073 resolve the operand with its own type because the context will impose a
3074 resulting type on the result of the multiplication by means of
3075 approriate conversion.
3077 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
3079 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
3080 the in-place initialization aggregate created for pragmas
3081 Initialize_Scalars or Normalize_Scalars is performed with checks
3084 2018-05-25 Arnaud Charlet <charlet@adacore.com>
3086 * exp_aggr.adb (Convert_To_Positional): Bump default for
3087 Max_Others_Replicate to 32. Update comments.
3088 * osint.ads (Unknown_Attributes): No longer pretend this is a constant.
3089 (No_File_Info_Cache): Initialize separately.

3100 2018-05-25 Ed Schonberg <schonberg@adacore.com>

3108 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
3110 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
3111 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
3112 into three distring cases rather than in one loop which attempts to
3113 handle all three cases. This rewrite eliminates an issue where the last
3114 frame of the stack cannot be freed, thus causing the memory range of a
3115 new frame to approach the overflow point of the memory index type.
3116 Since the overflow is logically treated as a
3117 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.

3176 in a generic unit and the actual is declared in an instance of it.
3177 There is currently no mechanism to relate an interface declared within
3178 a generic to the corresponding interface in an instance, so we must
3179 traverse the list of interfaces of the actual, looking for a name
3180 match, and verifying that that interface is declared in an instance.

3626 a constrained array component.
3627 * einfo.adb: Subprograms for Predicated_Parent.
3628 (Predicate_Function): Use new attribute.
3629 * exp_util.adb (Make_Predicate_Call): If the predicate function is not
3630 available for a subtype, retrieve it from the base type, which may have
3631 been frozen after the subtype declaration and not captured by the
3632 subtype declaration.
3633 * sem_aggr.adb (Resolve_Array_Aggregate): An Others association is
3634 legal within a generated initiqlization procedure, as may happen with a

3749 * sem_ch5.adb (Preanalyze_Range): The pre-analysis of the domain of
3750 iteration of an Ada2012 loop is performed to determine the type of the
3751 domain, but full analysis is performed once the loop is rewritten as a
3752 while-loop during expansion. The pre-analysis suppresses expansion; it
3753 must also suppress the generation of freeze nodes, which may otherwise
3754 appear in the wrong scope before rewritting.

4416 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
4417 delegate the secondary stack management when there is no suitable

4599 * binde.adb, par-ch6.adb, par-ch9.adb, sem_ch12.adb, sem_ch13.adb:
4602 2018-01-11 Justin Squirek <squirek@adacore.com>
4604 * par-ch6.adb (Scan_Body_Or_Expression_Function): Add additional check
4605 to make sure a given expression function is properly parenthesized.
4607 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
4609 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Check the
4610 categorization of a subprogram body which does not complete a previous
4613 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
4615 * sem_ch10.adb (Check_Private_Child_Unit): Ensure that the enclosing
4616 scope of package Ada is Standard.
4618 2018-01-11 Ed Schonberg <schonberg@adacore.com>
4620 * sem_ch13.adb (Replace_Type_Ref): Handle properly reference to a
4621 subcomponent of the current entity when building the body for a dynamic
4622 predicate function for a record with composite subcomponents.
4624 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
4626 * exp_aggr.adb (Convert_Aggr_In_Object_Decl): Update the call to
4627 Establish_Transient_Scope.
4628 (Convert_To_Assignments): Update the call to Establish_Transient_Scope.
4629 (Expand_Array_Aggregate): Update the call to Establish_Transient_Scope.
4630 * exp_ch6.adb (Expand_Call_Helper): Update the call to
4631 Establish_Transient_Scope.
4632 (Make_Build_In_Place_Call_In_Object_Declaration): Update the call to
4633 Establish_Transient_Scope.
4634 * exp_ch7.adb (Establish_Transient_Scope): Restructured. Delegate the
4635 management of the secondary stack to an enclosing scope if there is no
4636 suitable construct to wrap, and the transient scope was intended to
4637 manage the secondary stack.
4638 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
4639 is a valid boundary for a transient expression which comes from the
4640 statements of the alternative, otherwise alternatives cannot be
4641 wrapped. Assignments of controlled objects which have controlled
4642 actions suppressed now stop the traversal as there is no point in
4643 looking for an enclosing construct. Add several N_xxx_Body choices to
4644 the termination conditions for completeness.
4645 * exp_ch7.ads (Establish_Transient_Scope): Update the parameter profile
4646 and the associated comment on usage.
4647 * exp_smem.adb (Add_Shared_Var_Lock_Procs): Update the call to
4648 Establish_Transient_Scope.
4649 (Add_Write_After): Update the call to Establish_Transient_Scope.
4650 * sem_res.adb (Check_Initialization_Call): Removed.
4651 (Resolve_Actuals): Account for additional cases where finalization
4652 actions are required by utilizing predicate Needs_Finalization rather
4654 (Resolve_Call): Type initialization procedures can now utilize
4655 transient scopes to manage the secondary stack, thus preventing leaks
4656 during initialization. Remove the previous kludgy algorithm which
4657 attempts to manage the secondary stack at the object creation site.
4659 2018-01-11 Jerome Lambourg <lambourg@adacore.com>
4661 * libgnat/g-soliop__qnx.ads: New.

4700 2018-01-11 Ed Schonberg <schonberg@adacore.com>
4702 * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
4703 formsl type corresponding to the actual fixed point type is private,
4704 because in this case there can be no suspicious arithmetic operations
4705 in the generic unless they reference a formal subprogram. Clarify
4708 2018-01-11 Javier Miranda <miranda@adacore.com>
4710 * exp_util.adb (Remove_Side_Effects): No action done for functions
4711 returning class-wide types since it requires generating code using
4712 'reference and the CCG target has no secondary stack.

4729 to match what the Libadalang-based version does.

4732 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
4734 * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
4735 if it contains at least one component declaration employing a function
4736 call returning on the secondary stack.

4755 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
4756 has a delayed aspect which must be processed at the point the type is
4757 frozen. This mimics what is done when the predicate is provided by a

4770 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
4772 * libgnat/s-parame*.adb, libgnat/s-parame*.ads: Remove unneeded
4773 Default_Sec_Stack_Size.
4774 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
4775 limit check so that the integer index does not overflow. Check the
4776 dynamic stack allocation does not cause the secondary stack pointer to
4778 (SS_Info): Align colons.
4779 (SS_Init): Cover the case when bootstraping with an old compiler that
4780 does not set Default_SS_Size.
4782 2018-01-11 Ed Schonberg <schonberg@adacore.com>
4784 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
4785 legality of an inherited operation that may require overriding, ignore
4786 primitive_wrappers that correspond to explicit operations that override
4787 an interface primitive.
4788 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
4789 operation to which the class-wide expression applies is a protected op.
4790 with a primitive_wrapper, verify that the updated inherited expression
4791 does not contain an internal call to a protected function. This
4792 completes the implementation of AI12-0166.
4794 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
4796 * ali.adb: Document the remaining letters available for ALI lines.
4797 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
4798 * ali.ads: Update type With_Record. Field
4799 Implicit_With_From_Instantiation is no longer in use. Add field
4801 * csinfo.adb (CSinfo): Remove the setup for attribute
4802 Implicit_With_From_Instantiation.
4803 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
4804 either implicitly or explicitly withed.
4805 (Is_Implicit_With_Clause): New routine.
4806 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
4807 confusion with the with clause attribute by the same name.
4808 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
4809 * rtsfind.adb (Maybe_Add_With): Code cleanup.
4810 * sem_ch8.adb (Present_System_Aux): Code cleanup.
4811 * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
4813 (Implicit_With_On_Parent): Mark the with clause as generated for a
4815 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
4816 instantiation are no longer marked as Implicit_With_From_Instantiation
4817 because they are already marked as implicit.
4818 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
4819 which marks implicit with clauses as related to an instantiation.
4820 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
4821 (Parent_With): New routine.
4822 (Set_Implicit_With_From_Instantiation): Removed.
4823 (Set_Parent_With): New routine.
4824 * sinfo.ads: Update the documentation of attribute Implicit_With.
4825 Remove attribute Implicit_With_From_Instantiation along with

4836 entity when the enclosing construct is a body.
4838 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
4840 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
4841 Secondary_Stack_Size handling as a pragma is now generated for the
4842 corresponding aspect instead of an attribute. Pragma expression is
4843 relocated instead of evaluated. Discriminant of the corresponding
4844 record type is referenced rather than the type discriminant.
4845 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
4846 Secondary_Stack_Size rep item checks to only look for the pragma rep.
4847 * sem_ch13.adb (Analyze_One_Aspect): Transform
4848 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
4849 because the attribute does not have visibility on a task type's
4850 discriminants when the type's definition is expanded.
4851 (Analyze_Attribute_Definition_Clause): Remove handling of
4852 Attribute_Secondary_Stack_Size.
4853 * snames.adb-tmpl, snames.ads-tmpl: Remove
4854 Attribute_Secondary_Stack_Size, no longer used.

4860 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
4862 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
4863 individual action because the action may denote a complex expression,
4864 such as a case statement, which in turn may contain additional
4867 2018-01-11 Ed Schonberg <schonberg@adacore.com>
4869 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
4870 analysis on a copy of the expression with a copy of the index variable,
4871 because full expansion will rewrite construct into a loop with the
4872 original loop variable.
4873 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
4874 expression is an iterated component association. Full analysis takes
4875 place when construct is rewritten as a loop.
4876 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
4877 is not safe for in-place assignment.
4878 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
4879 entity with no homonym and no other entity in the scope.
4881 2018-01-11 Justin Squirek <squirek@adacore.com>
4883 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
4884 message to be printed on the pragma argument identifier.
4886 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
4888 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
4889 entity of the generated invariant procedure in order to construct a
4890 proper entity chain.
4892 2018-01-11 Piotr Trojanek <trojanek@adacore.com>

4899 * einfo.ads, einfo.adb (Activation_Record_Component,
4900 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
4901 Allow E_Discriminant.
4903 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
4905 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
4906 for atomic access once the component size is taken into account and
4907 also do it if the component type is Atomic or Volatile_Full_Access.
4909 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
