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

953 the same scope that have not been frozen yet.

979 2018-08-21 Ed Schonberg <schonberg@adacore.com>
981 * sem_ch6.adb (Check_Synchronized_Overriding): The conformance
982 between an overriding protected operation and the overridden
983 abstract progenitor operation requires subtype conformance;
984 requiring equality of return types in the case of a function is
985 too restrictive and leads to spurious errors when the return
986 type is a generic actual.

1011 (Check_Callable_Body): Assume permissions on globals and
1012 parameters depending on their modes then analyse the body
1014 (Check_Declaration): Consider both deep (including elementary
1015 access) object declarations and normal variables. First check
1016 whether the deep object is of Ownership Aspec True or not, then,
1017 depending on its initialization, assign the appropriate state.

1040 one expected (in the statement being analyzed).
1041 (Process_Path): Given an operation and a current state, call
1042 Perm_Error if there is any mismatch.
1043 (Return_Declarations, Return_Globals, Return_The_Global): Check
1044 the state of a given name at the end of the subprogram. These
1045 procedures may change depending on how we shall finally deal
1046 with globals and the rhs state in a move operation.

1048 Set_Perm_Prefixes, Setup_Globals, Setup_Parameter_Or_Global,

1554 outside of a subprogram body. This case was previously handled during

1556 we continued freezeing entities outside of the subprogram. Now, when
1557 climbing the parents chain to locate the correct placement for the
1558 freezeing node, we check if the entity can be frozen and only when no
1559 enclosing node is marked as Must_Not_Freeze the entity is frozen.

1571 Its code is basically the previous version of this routine but extended
1572 with an additional parameter which is used to specify if during
1573 preanalysis we are allowed to freeze entities. If the new parameter is
1574 True then the subtree root node is marked as Must_Not_Freeze and no
1575 entities are frozen during preanalysis.
1576 (Preanalyze_And_Resolve): Invokes the internal version of
1577 Preanalyze_And_Resolve without entity freezing.
1578 (Preanalyze_With_Freezing_And_Resolve): Invokes the internal version of

2629 * sem_ch3.adb (Access_Subprogram_Declaration): The flag
2630 Needs_Activation_Record is only needed on a subprogram type, not on a

2633 component type are anonymous access to subprograms, use the component
2634 type to obtain the proper value of Needs_Activation_Record flag for the

2640 comment about the memset case.
2642 2018-05-30 Bob Duff <duff@adacore.com>
2644 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
2645 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
2646 We need to analyze it as part of analyzing the block, so that if the
2647 call to Element that initializes Elmt_Decl returns on the secondary
2648 stack, the block will ss_mark/ss_release. This block is inside the
2649 loop; we don't want to leak memory until the loop exits. The purpose
2650 of analyzing Elmt_Decl first was to catch the error of modifying it,
2651 which is illegal because it's a loop parameter. The above causes us to
2652 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
2653 it on the Element entity, so we end up with an E_Variable node with the
2655 * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.
2656 * sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop
2657 parameter not allowed" error if Is_Loop_Parameter.
2658 * sem_util.adb (Is_Variable): Return False if Is_Loop_Parameter, to
2659 trigger the call to Diagnose_Non_Variable_Lhs.
2661 2018-05-30 Arnaud Charlet <charlet@adacore.com>

2664 * sem_eval.adb (Check_Non_Static_Context, Out_Of_Range): Ignore out of
2665 range values for System.Priority in CodePeer mode since the actual
2666 target compiler may provide a wider range.

2675 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
2676 a package body that is a compilation unit may contain blocks that
2677 declare local subprograms. In Subprogram_Unnesting Mode such
2678 subprograms must be handled as nested inside the (implicit) elaboration
2679 procedure that executes that statement part. To handle properly uplevel
2680 references we construct that subprogram explicitly, to contain blocks
2681 and inner subprograms, The statement part of the compilation unit
2682 becomes a call to this subprogram. This is only done if blocks are
2683 present in the statement list of the body.
2685 2018-05-30 Bob Duff <duff@adacore.com>

2695 for subprogram instantiations to enter callable entity into Subp table.

2752 (Collect_Primitive_Operations): Handle untagged private types completed
2753 with a derivation of an untagged private type whose full view is a
2754 tagged type. In such case, collecting the list of primitives we may
2755 find two equality primitives: one associated with the untagged private
2756 and another associated with the ultimate tagged type (and we must
2757 remove from the returned list this latter one).

3016 2018-05-28 Javier Miranda <miranda@adacore.com>
3018 * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
3019 value when converting a float value to a fixed-point value. This is
3020 required for CCG because it handles fixed-point types by means of
3021 unsigned integer type variables. The range check is now performed using

3058 2018-05-28 Ed Schonberg <schonberg@adacore.com>
3060 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
3061 when bounds of fixed type are static, to remove some spuerfluous
3062 implicit conversions and provide an accurate result when converting
3063 back and forth between the fixed point type and a floating point type.

3073 replaced, if any; all callers changed.
3074 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
3075 constant with private view so we take the address of that entity.
3076 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
3077 any; all callers changed. Handle N_Indexed_Component like
3078 N_Attribute_Reference. Add N_Type_Conversion case.
3079 (Visit_Node): Indexed references can be uplevel if the type isn't
3081 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
3082 been relocated, set first_named pointer in original node as well.

3086 * exp_aggr.adb (Flatten): Copy tree of expression in a component
3087 association with a range or a set of discrete choices, rather than

3114 description of the -D binder switch to reflect current usage.
3115 * gnat_ugn.texi: Regenerate.
3117 2018-05-28 Gary Dismukes <dismukes@adacore.com>
3119 * exp_ch3.adb: Minor reformatting

3142 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
3144 * sem_prag.adb (Process_Atomic_Independent_Shared_Volatile): Include
3145 the declarations of single concurrent types because they fall in the
3146 category of full type and object declarations.
3148 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
3150 * repinfo.adb (Compute_Max_Length): Skip _Parent component.

3155 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
3156 includes a call to function to which it applies. This may mean an
3157 omission of an attribute reference 'Result, in particular if the
3158 function is pqrameterless.
3160 2018-05-28 Justin Squirek <squirek@adacore.com>
3162 * sem_ch8.adb (Find_Expanded_Name): Add extra guard to make sure the

3167 * sem_res.adb (Resolve_Range): Re-resolve the low bound of a range in
3168 GNATprove mode, as the order of resolution (low then high) means that
3169 all the information is not available when resolving the low bound the
3172 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
3174 * repinfo.adb (List_Array_Info): Start with an explicit blank line and
3175 end with the linker section, if any.
3176 (List_Entities): Do not output the linker section for record types,
3177 array types and variables.
3178 (Print_Expr): Factor out common processing for unary operators and
3179 special values. Adjust and reorder the various cases.
3180 (List_Object_Info): End with the linker section, if any.
3181 (List_Record_Info): Likewise.
3182 (List_Type_Info): Do not start with a blank line.
3184 2018-05-25 Nicolas Roche <roche@adacore.com>

3194 (Task_Storage_Size): Remove unused type.
3196 2018-05-25 Ed Schonberg <schonberg@adacore.com>
3198 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
3199 of a fixed point type and the parent is a multiplying operation,
3200 resolve the operand with its own type because the context will impose a
3201 resulting type on the result of the multiplication by means of
3202 approriate conversion.
3204 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
3206 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
3207 the in-place initialization aggregate created for pragmas
3208 Initialize_Scalars or Normalize_Scalars is performed with checks
3211 2018-05-25 Arnaud Charlet <charlet@adacore.com>
3213 * exp_aggr.adb (Convert_To_Positional): Bump default for
3214 Max_Others_Replicate to 32. Update comments.

3227 2018-05-25 Ed Schonberg <schonberg@adacore.com>
3229 * exp_aggr.adb (Flatten): A quantified expression cannot be duplicated
3230 in an others clause to prevent visibility issues with the generated

3235 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
3237 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
3238 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
3239 into three distring cases rather than in one loop which attempts to
3240 handle all three cases. This rewrite eliminates an issue where the last
3241 frame of the stack cannot be freed, thus causing the memory range of a
3242 new frame to approach the overflow point of the memory index type.
3243 Since the overflow is logically treated as a
3244 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
3245 (SS_Allocate_Static): New routine. The routine factorizes the static
3246 secondary stack-related code from the former SS_Allocate.
3248 2018-05-25 Sergey Rybin <rybin@adacore.com>

3255 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
3256 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
3257 is created when the proper body of the stub is analyzed.
3258 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
3259 is the proper body of a subunit, the cloned body must be inserted in
3260 the declarative list that contains the stub.
3262 2018-05-25 Justin Squirek <squirek@adacore.com>
3264 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
3265 generate code for 6.5(8-10) so that we don't get an assertion error
3266 when dealing with an incomplete return type.
3268 2018-05-25 Arnaud Charlet <charlet@adacore.com>
3270 * pprint.adb (Expression_Name): Strip too long expressions to avoid
3271 carrying very large strings.

3297 2018-05-25 Ed Schonberg <schonberg@adacore.com>
3299 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
3300 Validate_Derived_Type_Instance, to verify that all interfaces
3301 implemented by the formal type are also implemented by the actual. The
3302 verification is complicated when an interface of the formal is declared
3303 in a generic unit and the actual is declared in an instance of it.
3304 There is currently no mechanism to relate an interface declared within
3305 a generic to the corresponding interface in an instance, so we must
3306 traverse the list of interfaces of the actual, looking for a name
3307 match, and verifying that that interface is declared in an instance.
3309 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
3311 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra
3312 assertions; replace function versions of Next_Formal/Next_Actual with

3324 for incremental looping. Remove references to Rel_Time and
3325 Relative_Timed_Wait.

3353 <E_Enumeration_Subtype>: Likewise for subtypes.
3354 <E_Record_Type>: Force the size of a storage unit on empty classes.
3355 * gcc-interface/utils.c (make_type_from_size) <BOOLEAN_TYPE>: Skip
3356 boolean types with precision 1 if the size is the expected one.

3378 in loops at the library level.
3380 2018-05-25 Ed Schonberg <schonberg@adacore.com>
3382 * sem_ch13.adb (Build_Predicate_Functions): The predicate function
3383 declaration is inserted into the tree and analyzed at that point, so
3384 should not be reinserted when the body is constructed. Inside a
3385 generic, ensure that the body is not inserted twice in the tree.
3387 2018-05-25 Yannick Moy <moy@adacore.com>

3877 iteration of an Ada2012 loop is performed to determine the type of the

4543 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
4544 delegate the secondary stack management when there is no suitable
4545 transient context, and the transient scope was intended to manage the

4762 management of the secondary stack to an enclosing scope if there is no
4763 suitable construct to wrap, and the transient scope was intended to
4764 manage the secondary stack.
4765 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
4766 is a valid boundary for a transient expression which comes from the
4767 statements of the alternative, otherwise alternatives cannot be
4768 wrapped. Assignments of controlled objects which have controlled
4769 actions suppressed now stop the traversal as there is no point in
4770 looking for an enclosing construct. Add several N_xxx_Body choices to
4771 the termination conditions for completeness.

4773 and the associated comment on usage.

4778 (Resolve_Actuals): Account for additional cases where finalization
4779 actions are required by utilizing predicate Needs_Finalization rather
4781 (Resolve_Call): Type initialization procedures can now utilize
4782 transient scopes to manage the secondary stack, thus preventing leaks
4783 during initialization. Remove the previous kludgy algorithm which
4784 attempts to manage the secondary stack at the object creation site.

4829 * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the

4832 in the generic unless they reference a formal subprogram. Clarify

4913 primitive_wrappers that correspond to explicit operations that override
4914 an interface primitive.
4915 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
4916 operation to which the class-wide expression applies is a protected op.
4917 with a primitive_wrapper, verify that the updated inherited expression
4918 does not contain an internal call to a protected function. This
4919 completes the implementation of AI12-0166.

4931 either implicitly or explicitly withed.
4932 (Is_Implicit_With_Clause): New routine.
4933 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
4934 confusion with the with clause attribute by the same name.

4946 which marks implicit with clauses as related to an instantiation.
4947 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
4948 (Parent_With): New routine.
4949 (Set_Implicit_With_From_Instantiation): Removed.

4967 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
4968 Secondary_Stack_Size handling as a pragma is now generated for the
4969 corresponding aspect instead of an attribute. Pragma expression is
4970 relocated instead of evaluated. Discriminant of the corresponding
4971 record type is referenced rather than the type discriminant.
4972 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
4973 Secondary_Stack_Size rep item checks to only look for the pragma rep.
4974 * sem_ch13.adb (Analyze_One_Aspect): Transform
4975 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
4976 because the attribute does not have visibility on a task type's

4996 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
4997 analysis on a copy of the expression with a copy of the index variable,
4998 because full expansion will rewrite construct into a loop with the
4999 original loop variable.
5000 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
5001 expression is an iterated component association. Full analysis takes
5002 place when construct is rewritten as a loop.
5003 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
5004 is not safe for in-place assignment.
5005 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
