329 in an instance, when the generic parameters include an interface type
330 and a abstract operation of that type, and the actuals in the instance
331 include an interface type and a corresponding abstract operation of it,

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

496 we continued freezeing entities outside of the subprogram. Now, when
497 climbing the parents chain to locate the correct placement for the
498 freezeing node, we check if the entity can be frozen and only when no
499 enclosing node is marked as Must_Not_Freeze the entity is frozen.
500 * sem_ch3.ads (Preanalyze_Default_Expression): Declaration moved to the
502 * sem_ch3.adb (Preanalyze_Default_Expression): Code adjusted to invoke
503 the new subprogram Preanalyze_With_Freezing_And_Resolve.

505 (Analyze_Expression_Function, Process_Formals): Invoke
506 Preanalyze_Formal_Expression instead of Preanalyze_Spec_Expression
507 since the analysis of the formals may freeze entities.

509 class-wide clone for eliminated subprograms.
510 * sem_res.ads, sem_res.adb (Preanalyze_And_Resolve): New subprogram.
511 Its code is basically the previous version of this routine but extended
512 with an additional parameter which is used to specify if during
513 preanalysis we are allowed to freeze entities. If the new parameter is
514 True then the subtree root node is marked as Must_Not_Freeze and no
515 entities are frozen during preanalysis.
516 (Preanalyze_And_Resolve): Invokes the internal version of
517 Preanalyze_And_Resolve without entity freezing.
518 (Preanalyze_With_Freezing_And_Resolve): Invokes the internal version of

1584 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
1585 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
1586 We need to analyze it as part of analyzing the block, so that if the
1587 call to Element that initializes Elmt_Decl returns on the secondary
1588 stack, the block will ss_mark/ss_release. This block is inside the
1589 loop; we don't want to leak memory until the loop exits. The purpose
1590 of analyzing Elmt_Decl first was to catch the error of modifying it,
1591 which is illegal because it's a loop parameter. The above causes us to
1592 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
1593 it on the Element entity, so we end up with an E_Variable node with the
1595 * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.
1596 * sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop
1597 parameter not allowed" error if Is_Loop_Parameter.
1598 * sem_util.adb (Is_Variable): Return False if Is_Loop_Parameter, to
1599 trigger the call to Diagnose_Non_Variable_Lhs.

1603 * checks.adb (Apply_Scalar_Range_Check):
1604 * sem_eval.adb (Check_Non_Static_Context, Out_Of_Range): Ignore out of
1605 range values for System.Priority in CodePeer mode since the actual
1606 target compiler may provide a wider range.

1613 2018-05-30 Ed Schonberg <schonberg@adacore.com>
1615 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
1616 a package body that is a compilation unit may contain blocks that
1617 declare local subprograms. In Subprogram_Unnesting Mode such
1618 subprograms must be handled as nested inside the (implicit) elaboration
1619 procedure that executes that statement part. To handle properly uplevel
1620 references we construct that subprogram explicitly, to contain blocks
1621 and inner subprograms, The statement part of the compilation unit
1622 becomes a call to this subprogram. This is only done if blocks are
1623 present in the statement list of the body.
1625 2018-05-30 Bob Duff <duff@adacore.com>

1635 for subprogram instantiations to enter callable entity into Subp table.

1639 * libgnat/s-secsta.adb: Reimplement the secondary stack support.
1640 * libgnat/s-secsta.ads: Update the documentation of all routines in the

1693 with a derivation of an untagged private type whose full view is a
1694 tagged type. In such case, collecting the list of primitives we may
1695 find two equality primitives: one associated with the untagged private

2015 constant with private view so we take the address of that entity.
2016 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
2017 any; all callers changed. Handle N_Indexed_Component like
2018 N_Attribute_Reference. Add N_Type_Conversion case.

2082 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
2084 * sem_prag.adb (Process_Atomic_Independent_Shared_Volatile): Include
2085 the declarations of single concurrent types because they fall in the
2086 category of full type and object declarations.
2088 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>

2095 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
2096 includes a call to function to which it applies. This may mean an
2097 omission of an attribute reference 'Result, in particular if the
2098 function is pqrameterless.
2100 2018-05-28 Justin Squirek <squirek@adacore.com>

2114 * repinfo.adb (List_Array_Info): Start with an explicit blank line and
2115 end with the linker section, if any.
2116 (List_Entities): Do not output the linker section for record types,
2117 array types and variables.
2118 (Print_Expr): Factor out common processing for unary operators and
2119 special values. Adjust and reorder the various cases.
2120 (List_Object_Info): End with the linker section, if any.
2121 (List_Record_Info): Likewise.

2127 that the result will be either -infinite or +infinite.

2136 2018-05-25 Ed Schonberg <schonberg@adacore.com>
2138 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
2139 of a fixed point type and the parent is a multiplying operation,
2140 resolve the operand with its own type because the context will impose a
2141 resulting type on the result of the multiplication by means of
2142 approriate conversion.
2144 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
2146 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
2147 the in-place initialization aggregate created for pragmas
2148 Initialize_Scalars or Normalize_Scalars is performed with checks
2151 2018-05-25 Arnaud Charlet <charlet@adacore.com>
2153 * exp_aggr.adb (Convert_To_Positional): Bump default for

2175 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
2177 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
2178 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
2179 into three distring cases rather than in one loop which attempts to
2180 handle all three cases. This rewrite eliminates an issue where the last
2181 frame of the stack cannot be freed, thus causing the memory range of a
2182 new frame to approach the overflow point of the memory index type.
2183 Since the overflow is logically treated as a
2184 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
2185 (SS_Allocate_Static): New routine. The routine factorizes the static
2186 secondary stack-related code from the former SS_Allocate.
2188 2018-05-25 Sergey Rybin <rybin@adacore.com>

2195 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
2196 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
2197 is created when the proper body of the stub is analyzed.
2198 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
2199 is the proper body of a subunit, the cloned body must be inserted in
2200 the declarative list that contains the stub.
2202 2018-05-25 Justin Squirek <squirek@adacore.com>
2204 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
2205 generate code for 6.5(8-10) so that we don't get an assertion error
2206 when dealing with an incomplete return type.
2208 2018-05-25 Arnaud Charlet <charlet@adacore.com>

2239 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
2240 Validate_Derived_Type_Instance, to verify that all interfaces
2241 implemented by the formal type are also implemented by the actual. The
2242 verification is complicated when an interface of the formal is declared
2243 in a generic unit and the actual is declared in an instance of it.
2244 There is currently no mechanism to relate an interface declared within
2245 a generic to the corresponding interface in an instance, so we must
2246 traverse the list of interfaces of the actual, looking for a name
2247 match, and verifying that that interface is declared in an instance.
2249 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
2251 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra
2252 assertions; replace function versions of Next_Formal/Next_Actual with

2318 in loops at the library level.
2320 2018-05-25 Ed Schonberg <schonberg@adacore.com>
2322 * sem_ch13.adb (Build_Predicate_Functions): The predicate function
2323 declaration is inserted into the tree and analyzed at that point, so
2324 should not be reinserted when the body is constructed. Inside a
2325 generic, ensure that the body is not inserted twice in the tree.

2817 iteration of an Ada2012 loop is performed to determine the type of the

3484 delegate the secondary stack management when there is no suitable
3485 transient context, and the transient scope was intended to manage the

3490 the comment on usage.
3491 (Find_Transient_Context): Change the initinte loop into a while loop.

3702 management of the secondary stack to an enclosing scope if there is no
3703 suitable construct to wrap, and the transient scope was intended to
3704 manage the secondary stack.
3705 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
3706 is a valid boundary for a transient expression which comes from the
3707 statements of the alternative, otherwise alternatives cannot be
3708 wrapped. Assignments of controlled objects which have controlled
3709 actions suppressed now stop the traversal as there is no point in
3710 looking for an enclosing construct. Add several N_xxx_Body choices to
3711 the termination conditions for completeness.

3713 and the associated comment on usage.

3718 (Resolve_Actuals): Account for additional cases where finalization
3719 actions are required by utilizing predicate Needs_Finalization rather
3721 (Resolve_Call): Type initialization procedures can now utilize
3722 transient scopes to manage the secondary stack, thus preventing leaks
3723 during initialization. Remove the previous kludgy algorithm which
3724 attempts to manage the secondary stack at the object creation site.

3769 * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the

3772 in the generic unless they reference a formal subprogram. Clarify

3853 primitive_wrappers that correspond to explicit operations that override
3854 an interface primitive.
3855 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
3856 operation to which the class-wide expression applies is a protected op.
3857 with a primitive_wrapper, verify that the updated inherited expression
3858 does not contain an internal call to a protected function. This
3859 completes the implementation of AI12-0166.

3871 either implicitly or explicitly withed.
3872 (Is_Implicit_With_Clause): New routine.
3873 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
3874 confusion with the with clause attribute by the same name.

3886 which marks implicit with clauses as related to an instantiation.
3887 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
3888 (Parent_With): New routine.
3889 (Set_Implicit_With_From_Instantiation): Removed.

3907 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
3908 Secondary_Stack_Size handling as a pragma is now generated for the
3909 corresponding aspect instead of an attribute. Pragma expression is
3910 relocated instead of evaluated. Discriminant of the corresponding
3911 record type is referenced rather than the type discriminant.
3912 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
3913 Secondary_Stack_Size rep item checks to only look for the pragma rep.
3914 * sem_ch13.adb (Analyze_One_Aspect): Transform
3915 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
3916 because the attribute does not have visibility on a task type's

3936 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
3937 analysis on a copy of the expression with a copy of the index variable,
3938 because full expansion will rewrite construct into a loop with the
3939 original loop variable.
3940 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
3941 expression is an iterated component association. Full analysis takes
3942 place when construct is rewritten as a loop.
3943 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
3944 is not safe for in-place assignment.
3945 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
