310 in an instance, when the generic parameters include an interface type
311 and a abstract operation of that type, and the actuals in the instance

475 outside of a subprogram body. This case was previously handled during
476 preanalysis; the frozen entities were remembered and left pending until
477 we continued freezeing entities outside of the subprogram. Now, when
478 climbing the parents chain to locate the correct placement for the
479 freezeing node, we check if the entity can be frozen and only when no
480 enclosing node is marked as Must_Not_Freeze the entity is frozen.
481 * sem_ch3.ads (Preanalyze_Default_Expression): Declaration moved to the
483 * sem_ch3.adb (Preanalyze_Default_Expression): Code adjusted to invoke
484 the new subprogram Preanalyze_With_Freezing_And_Resolve.
485 * sem_ch6.adb (Preanalyze_Formal_Expression): New subprogram.
486 (Analyze_Expression_Function, Process_Formals): Invoke
487 Preanalyze_Formal_Expression instead of Preanalyze_Spec_Expression
488 since the analysis of the formals may freeze entities.

490 class-wide clone for eliminated subprograms.
491 * sem_res.ads, sem_res.adb (Preanalyze_And_Resolve): New subprogram.
492 Its code is basically the previous version of this routine but extended
493 with an additional parameter which is used to specify if during
494 preanalysis we are allowed to freeze entities. If the new parameter is
495 True then the subtree root node is marked as Must_Not_Freeze and no
496 entities are frozen during preanalysis.
497 (Preanalyze_And_Resolve): Invokes the internal version of
498 Preanalyze_And_Resolve without entity freezing.
499 (Preanalyze_With_Freezing_And_Resolve): Invokes the internal version of
500 Prenalyze_And_Resolve with freezing enabled.

534 enclosing scope already handles the secondary stack, take into account
535 transient blocks nested in a block that do not manage the secondary
536 stack and are located within a loop.
538 2018-07-17 Ed Schonberg <schonberg@adacore.com>

1565 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
1566 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
1567 We need to analyze it as part of analyzing the block, so that if the
1568 call to Element that initializes Elmt_Decl returns on the secondary
1569 stack, the block will ss_mark/ss_release. This block is inside the
1570 loop; we don't want to leak memory until the loop exits. The purpose
1571 of analyzing Elmt_Decl first was to catch the error of modifying it,
1572 which is illegal because it's a loop parameter. The above causes us to

1574 it on the Element entity, so we end up with an E_Variable node with the

1577 * sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop
1578 parameter not allowed" error if Is_Loop_Parameter.
1579 * sem_util.adb (Is_Variable): Return False if Is_Loop_Parameter, to

1596 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
1597 a package body that is a compilation unit may contain blocks that
1598 declare local subprograms. In Subprogram_Unnesting Mode such
1599 subprograms must be handled as nested inside the (implicit) elaboration
1600 procedure that executes that statement part. To handle properly uplevel
1601 references we construct that subprogram explicitly, to contain blocks
1602 and inner subprograms, The statement part of the compilation unit
1603 becomes a call to this subprogram. This is only done if blocks are
1604 present in the statement list of the body.

1996 constant with private view so we take the address of that entity.
1997 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
1998 any; all callers changed. Handle N_Indexed_Component like

2097 (List_Entities): Do not output the linker section for record types,
2098 array types and variables.
2099 (Print_Expr): Factor out common processing for unary operators and
2100 special values. Adjust and reorder the various cases.
2101 (List_Object_Info): End with the linker section, if any.
2102 (List_Record_Info): Likewise.

2117 2018-05-25 Ed Schonberg <schonberg@adacore.com>
2119 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
2120 of a fixed point type and the parent is a multiplying operation,
2121 resolve the operand with its own type because the context will impose a
2122 resulting type on the result of the multiplication by means of
2123 approriate conversion.
2125 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
2127 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
2128 the in-place initialization aggregate created for pragmas
2129 Initialize_Scalars or Normalize_Scalars is performed with checks

2156 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
2158 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
2159 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
2160 into three distring cases rather than in one loop which attempts to
2161 handle all three cases. This rewrite eliminates an issue where the last
2162 frame of the stack cannot be freed, thus causing the memory range of a
2163 new frame to approach the overflow point of the memory index type.
2164 Since the overflow is logically treated as a
2165 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
2166 (SS_Allocate_Static): New routine. The routine factorizes the static
2167 secondary stack-related code from the former SS_Allocate.
2169 2018-05-25 Sergey Rybin <rybin@adacore.com>

2176 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
2177 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
2178 is created when the proper body of the stub is analyzed.
2179 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
2180 is the proper body of a subunit, the cloned body must be inserted in
2181 the declarative list that contains the stub.
2183 2018-05-25 Justin Squirek <squirek@adacore.com>
2185 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
2186 generate code for 6.5(8-10) so that we don't get an assertion error
2187 when dealing with an incomplete return type.
2189 2018-05-25 Arnaud Charlet <charlet@adacore.com>

2220 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
2221 Validate_Derived_Type_Instance, to verify that all interfaces
2222 implemented by the formal type are also implemented by the actual. The
2223 verification is complicated when an interface of the formal is declared
2224 in a generic unit and the actual is declared in an instance of it.
2225 There is currently no mechanism to relate an interface declared within
2226 a generic to the corresponding interface in an instance, so we must
2227 traverse the list of interfaces of the actual, looking for a name
2228 match, and verifying that that interface is declared in an instance.
2230 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
2232 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra
2233 assertions; replace function versions of Next_Formal/Next_Actual with

2299 in loops at the library level.
2301 2018-05-25 Ed Schonberg <schonberg@adacore.com>
2303 * sem_ch13.adb (Build_Predicate_Functions): The predicate function
2304 declaration is inserted into the tree and analyzed at that point, so
2305 should not be reinserted when the body is constructed. Inside a
2306 generic, ensure that the body is not inserted twice in the tree.

2798 iteration of an Ada2012 loop is performed to determine the type of the

3464 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
3465 delegate the secondary stack management when there is no suitable
3466 transient context, and the transient scope was intended to manage the

3471 the comment on usage.
3472 (Find_Transient_Context): Change the initinte loop into a while loop.

3603 * exp_ch6.adb (Make_Build_In_Place_Call_In_Object_Declaration): Handle
3604 properly object declarations with initializations that are
3605 build-in-place function calls, when there is an address specification,
3606 either as an aspect specification or an explicit attribute
3607 specification clause, for the initialized object.
3608 * freeze.adb (Check_Address_Clause): Do not remove side-effects from
3609 initial expressions in the case of a build-in-place call.
3611 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
3613 * sem_eval.adb (Is_Null_Range): Retrieve the full view when called on a
3614 private (sub)type; refactor to avoid early return statement.

3626 replicated by Is_Declaration.
3627 * sem_util.ads (Is_Declaration): New parameter profile. Update the

3650 2018-01-11 Justin Squirek <squirek@adacore.com>
3652 * par-ch6.adb (Scan_Body_Or_Expression_Function): Add additional check
3653 to make sure a given expression function is properly parenthesized.

3664 scope of package Ada is Standard.
3666 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3668 * sem_ch13.adb (Replace_Type_Ref): Handle properly reference to a
3669 subcomponent of the current entity when building the body for a dynamic
3670 predicate function for a record with composite subcomponents.

3682 * exp_ch7.adb (Establish_Transient_Scope): Restructured. Delegate the
3683 management of the secondary stack to an enclosing scope if there is no
3684 suitable construct to wrap, and the transient scope was intended to
3685 manage the secondary stack.
3686 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
3687 is a valid boundary for a transient expression which comes from the
3688 statements of the alternative, otherwise alternatives cannot be
3689 wrapped. Assignments of controlled objects which have controlled
3690 actions suppressed now stop the traversal as there is no point in
3691 looking for an enclosing construct. Add several N_xxx_Body choices to
3692 the termination conditions for completeness.
3693 * exp_ch7.ads (Establish_Transient_Scope): Update the parameter profile
3694 and the associated comment on usage.
3695 * exp_smem.adb (Add_Shared_Var_Lock_Procs): Update the call to
3696 Establish_Transient_Scope.

3699 (Resolve_Actuals): Account for additional cases where finalization
3700 actions are required by utilizing predicate Needs_Finalization rather
3702 (Resolve_Call): Type initialization procedures can now utilize
3703 transient scopes to manage the secondary stack, thus preventing leaks
3704 during initialization. Remove the previous kludgy algorithm which
3705 attempts to manage the secondary stack at the object creation site.
3707 2018-01-11 Jerome Lambourg <lambourg@adacore.com>
3709 * libgnat/g-soliop__qnx.ads: New.

3748 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3750 * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
3751 formsl type corresponding to the actual fixed point type is private,
3752 because in this case there can be no suspicious arithmetic operations
3753 in the generic unless they reference a formal subprogram. Clarify
3756 2018-01-11 Javier Miranda <miranda@adacore.com>
3758 * exp_util.adb (Remove_Side_Effects): No action done for functions
3759 returning class-wide types since it requires generating code using
3760 'reference and the CCG target has no secondary stack.

3803 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
3804 has a delayed aspect which must be processed at the point the type is

3832 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
3833 legality of an inherited operation that may require overriding, ignore
3834 primitive_wrappers that correspond to explicit operations that override
3835 an interface primitive.
3836 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
3837 operation to which the class-wide expression applies is a protected op.
3838 with a primitive_wrapper, verify that the updated inherited expression
3839 does not contain an internal call to a protected function. This
3840 completes the implementation of AI12-0166.
3842 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3844 * ali.adb: Document the remaining letters available for ALI lines.

3849 * csinfo.adb (CSinfo): Remove the setup for attribute
3850 Implicit_With_From_Instantiation.
3851 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
3852 either implicitly or explicitly withed.
3853 (Is_Implicit_With_Clause): New routine.
3854 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
3855 confusion with the with clause attribute by the same name.

3863 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
3864 instantiation are no longer marked as Implicit_With_From_Instantiation
3865 because they are already marked as implicit.
3866 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
3867 which marks implicit with clauses as related to an instantiation.
3868 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
3869 (Parent_With): New routine.
3870 (Set_Implicit_With_From_Instantiation): Removed.
3871 (Set_Parent_With): New routine.

3888 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
3889 Secondary_Stack_Size handling as a pragma is now generated for the
3890 corresponding aspect instead of an attribute. Pragma expression is
3891 relocated instead of evaluated. Discriminant of the corresponding
3892 record type is referenced rather than the type discriminant.
3893 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
3894 Secondary_Stack_Size rep item checks to only look for the pragma rep.
3895 * sem_ch13.adb (Analyze_One_Aspect): Transform
3896 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
3897 because the attribute does not have visibility on a task type's

3917 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
3918 analysis on a copy of the expression with a copy of the index variable,
3919 because full expansion will rewrite construct into a loop with the
3920 original loop variable.
3921 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
3922 expression is an iterated component association. Full analysis takes
3923 place when construct is rewritten as a loop.
3924 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
3925 is not safe for in-place assignment.
3926 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
