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

416 Its code is basically the previous version of this routine but extended
417 with an additional parameter which is used to specify if during
418 preanalysis we are allowed to freeze entities. If the new parameter is
419 True then the subtree root node is marked as Must_Not_Freeze and no
420 entities are frozen during preanalysis.
421 (Preanalyze_And_Resolve): Invokes the internal version of
422 Preanalyze_And_Resolve without entity freezing.
423 (Preanalyze_With_Freezing_And_Resolve): Invokes the internal version of

464 * sem_util.adb (Enclosing_Subprogram): Protected entries and task
465 entries must be treated separately: task entries are within the

1344 * exp_ch4.adb (Expand_Modular_Addition, Expand_Modular_Subtraction):
1345 Convert all operands of the generated code to Standard.Unsigned, to
1346 prevent spurious visibility errors. This is needed when the generated

1485 comment about the memset case.
1487 2018-05-30 Bob Duff <duff@adacore.com>
1489 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
1490 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
1491 We need to analyze it as part of analyzing the block, so that if the
1492 call to Element that initializes Elmt_Decl returns on the secondary
1493 stack, the block will ss_mark/ss_release. This block is inside the
1494 loop; we don't want to leak memory until the loop exits. The purpose
1495 of analyzing Elmt_Decl first was to catch the error of modifying it,
1496 which is illegal because it's a loop parameter. The above causes us to
1497 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
1498 it on the Element entity, so we end up with an E_Variable node with the
1500 * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.
1501 * sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop
1502 parameter not allowed" error if Is_Loop_Parameter.
1503 * sem_util.adb (Is_Variable): Return False if Is_Loop_Parameter, to
1504 trigger the call to Diagnose_Non_Variable_Lhs.

1518 2018-05-30 Ed Schonberg <schonberg@adacore.com>
1520 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
1521 a package body that is a compilation unit may contain blocks that
1522 declare local subprograms. In Subprogram_Unnesting Mode such
1523 subprograms must be handled as nested inside the (implicit) elaboration
1524 procedure that executes that statement part. To handle properly uplevel
1525 references we construct that subprogram explicitly, to contain blocks
1526 and inner subprograms, The statement part of the compilation unit
1527 becomes a call to this subprogram. This is only done if blocks are
1528 present in the statement list of the body.

1540 for subprogram instantiations to enter callable entity into Subp table.

1597 (Collect_Primitive_Operations): Handle untagged private types completed
1598 with a derivation of an untagged private type whose full view is a

1839 of actual have uplevel references.
1841 2018-05-28 Ed Schonberg <schonberg@adacore.com>

1863 * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
1864 value when converting a float value to a fixed-point value. This is

1898 * einfo.ads, einfo.adb (Needs_Activation_Record): New flag on

1918 replaced, if any; all callers changed.
1919 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
1920 constant with private view so we take the address of that entity.
1921 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
1922 any; all callers changed. Handle N_Indexed_Component like
1923 N_Attribute_Reference. Add N_Type_Conversion case.

1926 (Unnest_Subprograms): Don't rewrite if no reference given. If call has

1931 * exp_aggr.adb (Flatten): Copy tree of expression in a component
1932 association with a range or a set of discrete choices, rather than

2080 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
2082 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
2083 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
2084 into three distring cases rather than in one loop which attempts to
2085 handle all three cases. This rewrite eliminates an issue where the last
2086 frame of the stack cannot be freed, thus causing the memory range of a
2087 new frame to approach the overflow point of the memory index type.
2088 Since the overflow is logically treated as a
2089 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
2090 (SS_Allocate_Static): New routine. The routine factorizes the static
2091 secondary stack-related code from the former SS_Allocate.

2101 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone

2103 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
2104 is the proper body of a subunit, the cloned body must be inserted in
2105 the declarative list that contains the stub.

2144 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
2145 Validate_Derived_Type_Instance, to verify that all interfaces
2146 implemented by the formal type are also implemented by the actual. The
2147 verification is complicated when an interface of the formal is declared
2148 in a generic unit and the actual is declared in an instance of it.
2149 There is currently no mechanism to relate an interface declared within
2150 a generic to the corresponding interface in an instance, so we must
2151 traverse the list of interfaces of the actual, looking for a name
2152 match, and verifying that that interface is declared in an instance.

2600 (Predicate_Function): Use new attribute.
2601 * exp_util.adb (Make_Predicate_Call): If the predicate function is not

2722 iteration of an Ada2012 loop is performed to determine the type of the
2723 domain, but full analysis is performed once the loop is rewritten as a

3388 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
3389 delegate the secondary stack management when there is no suitable
3390 transient context, and the transient scope was intended to manage the

3546 * ghost.ads (Check_Ghost_Type): New routine.
3547 * sem_util.adb (Is_Declaration): Reimplemented. The routine can now
3548 consider specific subsets of declarations.
3549 (Is_Declaration_Other_Than_Renaming): Removed. Its functionality is
3550 replicated by Is_Declaration.
3551 * sem_util.ads (Is_Declaration): New parameter profile. Update the
3553 (Is_Declaration_Other_Than_Renaming): Removed.
3555 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3557 * sem_ch5.adb (Analyze_Assignment): Assignments to variables that act
3558 as Part_Of consituents of single protected types are illegal when they
3559 take place inside a protected function.
3560 (Diagnose_Non_Variable_Lhs): Use Within_Function to check for an
3562 (Is_Protected_Part_Of_Constituent): New routine.
3563 (Within_Function): New routine.

3567 Bump copyright notices to 2018.
3569 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3571 * binde.adb, par-ch6.adb, par-ch9.adb, sem_ch12.adb, sem_ch13.adb:
3574 2018-01-11 Justin Squirek <squirek@adacore.com>
3576 * par-ch6.adb (Scan_Body_Or_Expression_Function): Add additional check
3577 to make sure a given expression function is properly parenthesized.
3579 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3581 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Check the
3582 categorization of a subprogram body which does not complete a previous
3585 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3587 * sem_ch10.adb (Check_Private_Child_Unit): Ensure that the enclosing
3588 scope of package Ada is Standard.
3590 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3592 * sem_ch13.adb (Replace_Type_Ref): Handle properly reference to a
3593 subcomponent of the current entity when building the body for a dynamic
3594 predicate function for a record with composite subcomponents.
3596 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>

3604 (Make_Build_In_Place_Call_In_Object_Declaration): Update the call to
3605 Establish_Transient_Scope.
3606 * exp_ch7.adb (Establish_Transient_Scope): Restructured. Delegate the
3607 management of the secondary stack to an enclosing scope if there is no
3608 suitable construct to wrap, and the transient scope was intended to
3609 manage the secondary stack.
3610 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
3611 is a valid boundary for a transient expression which comes from the
3612 statements of the alternative, otherwise alternatives cannot be
3613 wrapped. Assignments of controlled objects which have controlled
3614 actions suppressed now stop the traversal as there is no point in
3615 looking for an enclosing construct. Add several N_xxx_Body choices to
3616 the termination conditions for completeness.
3617 * exp_ch7.ads (Establish_Transient_Scope): Update the parameter profile
3618 and the associated comment on usage.
3619 * exp_smem.adb (Add_Shared_Var_Lock_Procs): Update the call to
3620 Establish_Transient_Scope.
3621 (Add_Write_After): Update the call to Establish_Transient_Scope.
3622 * sem_res.adb (Check_Initialization_Call): Removed.
3623 (Resolve_Actuals): Account for additional cases where finalization
3624 actions are required by utilizing predicate Needs_Finalization rather
3626 (Resolve_Call): Type initialization procedures can now utilize
3627 transient scopes to manage the secondary stack, thus preventing leaks
3628 during initialization. Remove the previous kludgy algorithm which
3629 attempts to manage the secondary stack at the object creation site.
3631 2018-01-11 Jerome Lambourg <lambourg@adacore.com>
3633 * libgnat/g-soliop__qnx.ads: New.

3670 * gnat_rm.texi: Regenerate.
3672 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3674 * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
3675 formsl type corresponding to the actual fixed point type is private,
3676 because in this case there can be no suspicious arithmetic operations
3677 in the generic unless they reference a formal subprogram. Clarify
3680 2018-01-11 Javier Miranda <miranda@adacore.com>
3682 * exp_util.adb (Remove_Side_Effects): No action done for functions
3683 returning class-wide types since it requires generating code using
3684 'reference and the CCG target has no secondary stack.
3685 * gnat1drv.adb: Disable building static dispatch tables when generating

3696 * libgnat/s-os_lib.adb (Normalize_Pathname): New implementation.
3698 2018-01-11 Bob Duff <duff@adacore.com>
3700 * doc/gnat_ugn/gnat_utility_programs.rst: Rewrite gnatpp documentation
3701 to match what the Libadalang-based version does.
3702 * doc/gnat_ugn/about_this_guide.rst: Update reference.
3704 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3706 * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
3707 if it contains at least one component declaration employing a function
3708 call returning on the secondary stack.
3710 2018-01-11 Yannick Moy <moy@adacore.com>

3725 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3727 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
3728 has a delayed aspect which must be processed at the point the type is
3729 frozen. This mimics what is done when the predicate is provided by a

3745 Default_Sec_Stack_Size.
3746 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
3747 limit check so that the integer index does not overflow. Check the
3748 dynamic stack allocation does not cause the secondary stack pointer to
3750 (SS_Info): Align colons.
3751 (SS_Init): Cover the case when bootstraping with an old compiler that
3752 does not set Default_SS_Size.
3754 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3756 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
3757 legality of an inherited operation that may require overriding, ignore
3758 primitive_wrappers that correspond to explicit operations that override
3759 an interface primitive.
3760 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
3761 operation to which the class-wide expression applies is a protected op.
3762 with a primitive_wrapper, verify that the updated inherited expression
3763 does not contain an internal call to a protected function. This
3764 completes the implementation of AI12-0166.
3766 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3768 * ali.adb: Document the remaining letters available for ALI lines.
3769 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
3770 * ali.ads: Update type With_Record. Field
3771 Implicit_With_From_Instantiation is no longer in use. Add field
3773 * csinfo.adb (CSinfo): Remove the setup for attribute
3774 Implicit_With_From_Instantiation.
3775 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
3776 either implicitly or explicitly withed.
3777 (Is_Implicit_With_Clause): New routine.
3778 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
3779 confusion with the with clause attribute by the same name.
3780 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
3781 * rtsfind.adb (Maybe_Add_With): Code cleanup.
3782 * sem_ch8.adb (Present_System_Aux): Code cleanup.

3785 (Implicit_With_On_Parent): Mark the with clause as generated for a
3787 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
3788 instantiation are no longer marked as Implicit_With_From_Instantiation
3789 because they are already marked as implicit.
3790 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
3791 which marks implicit with clauses as related to an instantiation.
3792 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
3793 (Parent_With): New routine.
3794 (Set_Implicit_With_From_Instantiation): Removed.
3795 (Set_Parent_With): New routine.
3796 * sinfo.ads: Update the documentation of attribute Implicit_With.

3808 entity when the enclosing construct is a body.
3810 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
3812 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
3813 Secondary_Stack_Size handling as a pragma is now generated for the
3814 corresponding aspect instead of an attribute. Pragma expression is
3815 relocated instead of evaluated. Discriminant of the corresponding
3816 record type is referenced rather than the type discriminant.
3817 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
3818 Secondary_Stack_Size rep item checks to only look for the pragma rep.
3819 * sem_ch13.adb (Analyze_One_Aspect): Transform
3820 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
3821 because the attribute does not have visibility on a task type's

3823 (Analyze_Attribute_Definition_Clause): Remove handling of
3824 Attribute_Secondary_Stack_Size.
3825 * snames.adb-tmpl, snames.ads-tmpl: Remove
3826 Attribute_Secondary_Stack_Size, no longer used.

3834 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
3835 individual action because the action may denote a complex expression,
3836 such as a case statement, which in turn may contain additional
3839 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3841 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
3842 analysis on a copy of the expression with a copy of the index variable,
3843 because full expansion will rewrite construct into a loop with the
3844 original loop variable.
3845 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
3846 expression is an iterated component association. Full analysis takes
3847 place when construct is rewritten as a loop.
3848 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
3849 is not safe for in-place assignment.
3850 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
3851 entity with no homonym and no other entity in the scope.
3853 2018-01-11 Justin Squirek <squirek@adacore.com>

3856 message to be printed on the pragma argument identifier.

3860 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
3861 entity of the generated invariant procedure in order to construct a
3862 proper entity chain.

3873 Allow E_Discriminant.
3875 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
3877 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
3878 for atomic access once the component size is taken into account and
3879 also do it if the component type is Atomic or Volatile_Full_Access.
3881 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
