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

332 we continued freezeing entities outside of the subprogram. Now, when
333 climbing the parents chain to locate the correct placement for the

347 Its code is basically the previous version of this routine but extended
348 with an additional parameter which is used to specify if during
349 preanalysis we are allowed to freeze entities. If the new parameter is
350 True then the subtree root node is marked as Must_Not_Freeze and no
351 entities are frozen during preanalysis.
352 (Preanalyze_And_Resolve): Invokes the internal version of
353 Preanalyze_And_Resolve without entity freezing.
354 (Preanalyze_With_Freezing_And_Resolve): Invokes the internal version of

1275 * exp_ch4.adb (Expand_Modular_Addition, Expand_Modular_Subtraction):
1276 Convert all operands of the generated code to Standard.Unsigned, to
1277 prevent spurious visibility errors. This is needed when the generated

1418 2018-05-30 Bob Duff <duff@adacore.com>
1420 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
1421 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
1422 We need to analyze it as part of analyzing the block, so that if the
1423 call to Element that initializes Elmt_Decl returns on the secondary
1424 stack, the block will ss_mark/ss_release. This block is inside the
1425 loop; we don't want to leak memory until the loop exits. The purpose
1426 of analyzing Elmt_Decl first was to catch the error of modifying it,
1427 which is illegal because it's a loop parameter. The above causes us to
1428 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
1429 it on the Element entity, so we end up with an E_Variable node with the
1431 * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.
1432 * sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop
1433 parameter not allowed" error if Is_Loop_Parameter.
1434 * sem_util.adb (Is_Variable): Return False if Is_Loop_Parameter, to

1449 2018-05-30 Ed Schonberg <schonberg@adacore.com>
1451 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
1452 a package body that is a compilation unit may contain blocks that
1453 declare local subprograms. In Subprogram_Unnesting Mode such
1454 subprograms must be handled as nested inside the (implicit) elaboration
1455 procedure that executes that statement part. To handle properly uplevel
1456 references we construct that subprogram explicitly, to contain blocks
1457 and inner subprograms, The statement part of the compilation unit
1458 becomes a call to this subprogram. This is only done if blocks are
1459 present in the statement list of the body.

1471 for subprogram instantiations to enter callable entity into Subp table.

1531 find two equality primitives: one associated with the untagged private

1766 references, examine index expressions or associated expressions as well
1767 to record uplevel references.
1768 (Vist_Node): For function and procedure calls, if a formal is an
1769 unconstrained array and the actual is constrained, check whether bounds
1770 of actual have uplevel references.
1772 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1774 * einfo.ads, einfo.adb: Exceptions can be uplevel references, and thus
1775 they can appear as components of activation records.

1787 * exp_unst.adb (Check_Static_Type): For a record subtype, check
1788 discriminant constraints as well.

1790 done for indexed components and slices.
1792 2018-05-28 Javier Miranda <miranda@adacore.com>
1794 * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
1795 value when converting a float value to a fixed-point value. This is
1796 required for CCG because it handles fixed-point types by means of
1797 unsigned integer type variables. The range check is now performed using
1798 the integer value stored in this temporary.
1800 2018-05-28 Yannick Moy <moy@adacore.com>

1823 component type, do not expand array equality using the unconstrained
1824 base type, except for the case where the bounds of the type depend on a
1827 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1829 * einfo.ads, einfo.adb (Needs_Activation_Record): New flag on
1830 access-to-subprogram types, to indicate that an indirect call through
1831 such a type requires an activation record when compiling for LLVM.
1832 * sem_ch3.adb (Access_Subprogram_Declaration): Set new flag as needed.
1834 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1836 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
1837 when bounds of fixed type are static, to remove some spuerfluous
1838 implicit conversions and provide an accurate result when converting
1839 back and forth between the fixed point type and a floating point type.

1846 2018-05-28 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
1848 * exp_unst.adb (Check_Static_Type): Add argument to indicate node to be
1849 replaced, if any; all callers changed.
1850 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
1851 constant with private view so we take the address of that entity.
1852 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
1853 any; all callers changed. Handle N_Indexed_Component like
1854 N_Attribute_Reference. Add N_Type_Conversion case.
1855 (Visit_Node): Indexed references can be uplevel if the type isn't
1857 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
1858 been relocated, set first_named pointer in original node as well.
1860 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1862 * exp_aggr.adb (Flatten): Copy tree of expression in a component
1863 association with a range or a set of discrete choices, rather than
1864 relocating the node. This avoids inconsistencies in the tree when
1865 handling nested subprograms with uplevel references for LLVM.

1931 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
1932 includes a call to function to which it applies. This may mean an
1933 omission of an attribute reference 'Result, in particular if the
1934 function is pqrameterless.
1936 2018-05-28 Justin Squirek <squirek@adacore.com>

1952 (List_Entities): Do not output the linker section for record types,
1953 array types and variables.
1954 (Print_Expr): Factor out common processing for unary operators and
1955 special values. Adjust and reorder the various cases.
1956 (List_Object_Info): End with the linker section, if any.
1957 (List_Record_Info): Likewise.
1958 (List_Type_Info): Do not start with a blank line.
1960 2018-05-25 Nicolas Roche <roche@adacore.com>
1962 * libgnat/s-valrea.adb (Scan_Real): Abort computation once it is sure
1963 that the result will be either -infinite or +infinite.
1965 2018-05-25 Patrick Bernardi <bernardi@adacore.com>
1967 * libgnat/s-parame.ads, libgnat/s-parame__vxworks.ads,

1969 Expand range of type to match the address space of the target.
1970 (Task_Storage_Size): Remove unused type.
1972 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1974 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
1975 of a fixed point type and the parent is a multiplying operation,
1976 resolve the operand with its own type because the context will impose a
1977 resulting type on the result of the multiplication by means of
1978 approriate conversion.
1980 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1982 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
1983 the in-place initialization aggregate created for pragmas
1984 Initialize_Scalars or Normalize_Scalars is performed with checks
1987 2018-05-25 Arnaud Charlet <charlet@adacore.com>
1989 * exp_aggr.adb (Convert_To_Positional): Bump default for
1990 Max_Others_Replicate to 32. Update comments.
1991 * osint.ads (Unknown_Attributes): No longer pretend this is a constant.
1992 (No_File_Info_Cache): Initialize separately.

2011 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
2013 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
2014 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
2015 into three distring cases rather than in one loop which attempts to
2016 handle all three cases. This rewrite eliminates an issue where the last
2017 frame of the stack cannot be freed, thus causing the memory range of a
2018 new frame to approach the overflow point of the memory index type.
2019 Since the overflow is logically treated as a
2020 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
2021 (SS_Allocate_Static): New routine. The routine factorizes the static
2022 secondary stack-related code from the former SS_Allocate.
2024 2018-05-25 Sergey Rybin <rybin@adacore.com>
2026 * doc/gnat_ugn/gnat_and_program_execution.rst: Add description of '-U'
2027 option for gnatelim.

2031 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
2032 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
2033 is created when the proper body of the stub is analyzed.
2034 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
2035 is the proper body of a subunit, the cloned body must be inserted in
2036 the declarative list that contains the stub.
2038 2018-05-25 Justin Squirek <squirek@adacore.com>
2040 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
2041 generate code for 6.5(8-10) so that we don't get an assertion error
2042 when dealing with an incomplete return type.
2044 2018-05-25 Arnaud Charlet <charlet@adacore.com>

2075 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
2076 Validate_Derived_Type_Instance, to verify that all interfaces
2077 implemented by the formal type are also implemented by the actual. The
2078 verification is complicated when an interface of the formal is declared
2079 in a generic unit and the actual is declared in an instance of it.
2080 There is currently no mechanism to relate an interface declared within
2081 a generic to the corresponding interface in an instance, so we must
2082 traverse the list of interfaces of the actual, looking for a name
2083 match, and verifying that that interface is declared in an instance.

2158 * sem_ch13.adb (Build_Predicate_Functions): The predicate function
2159 declaration is inserted into the tree and analyzed at that point, so
2160 should not be reinserted when the body is constructed. Inside a
2161 generic, ensure that the body is not inserted twice in the tree.

3542 is a valid boundary for a transient expression which comes from the
3543 statements of the alternative, otherwise alternatives cannot be
3544 wrapped. Assignments of controlled objects which have controlled
3545 actions suppressed now stop the traversal as there is no point in
3546 looking for an enclosing construct. Add several N_xxx_Body choices to
3547 the termination conditions for completeness.
3548 * exp_ch7.ads (Establish_Transient_Scope): Update the parameter profile
3549 and the associated comment on usage.
3550 * exp_smem.adb (Add_Shared_Var_Lock_Procs): Update the call to
3551 Establish_Transient_Scope.
3552 (Add_Write_After): Update the call to Establish_Transient_Scope.
3553 * sem_res.adb (Check_Initialization_Call): Removed.
3554 (Resolve_Actuals): Account for additional cases where finalization
3555 actions are required by utilizing predicate Needs_Finalization rather
3557 (Resolve_Call): Type initialization procedures can now utilize
3558 transient scopes to manage the secondary stack, thus preventing leaks
3559 during initialization. Remove the previous kludgy algorithm which
3560 attempts to manage the secondary stack at the object creation site.
3562 2018-01-11 Jerome Lambourg <lambourg@adacore.com>
3564 * libgnat/g-soliop__qnx.ads: New.

3601 * gnat_rm.texi: Regenerate.
3603 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3605 * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
3606 formsl type corresponding to the actual fixed point type is private,
3607 because in this case there can be no suspicious arithmetic operations
3608 in the generic unless they reference a formal subprogram. Clarify
3611 2018-01-11 Javier Miranda <miranda@adacore.com>
3613 * exp_util.adb (Remove_Side_Effects): No action done for functions
3614 returning class-wide types since it requires generating code using
3615 'reference and the CCG target has no secondary stack.
3616 * gnat1drv.adb: Disable building static dispatch tables when generating
3619 2018-01-11 Piotr Trojanek <trojanek@adacore.com>

3623 (File_Type): Add Default_Initial_Condition aspect.
3625 2018-01-11 Pascal Obry <obry@adacore.com>
3627 * libgnat/s-os_lib.adb (Normalize_Pathname): New implementation.
3629 2018-01-11 Bob Duff <duff@adacore.com>
3631 * doc/gnat_ugn/gnat_utility_programs.rst: Rewrite gnatpp documentation
3632 to match what the Libadalang-based version does.
3633 * doc/gnat_ugn/about_this_guide.rst: Update reference.
3635 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3637 * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
3638 if it contains at least one component declaration employing a function
3639 call returning on the secondary stack.
3641 2018-01-11 Yannick Moy <moy@adacore.com>
3643 * doc/gnat_rm/standard_and_implementation_defined_restrictions.rst:

3654 sem_res.adb, sem_util.adb: Minor reformatting.
3656 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3658 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
3659 has a delayed aspect which must be processed at the point the type is
3660 frozen. This mimics what is done when the predicate is provided by a
3663 2018-01-11 Doug Rupp <rupp@adacore.com>
3665 * init.c (vxworks): Add macro checks for __aarch64__.

3673 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
3675 * libgnat/s-parame*.adb, libgnat/s-parame*.ads: Remove unneeded
3676 Default_Sec_Stack_Size.
3677 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
3678 limit check so that the integer index does not overflow. Check the
3679 dynamic stack allocation does not cause the secondary stack pointer to
3681 (SS_Info): Align colons.
3682 (SS_Init): Cover the case when bootstraping with an old compiler that
3683 does not set Default_SS_Size.
3685 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3687 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
3688 legality of an inherited operation that may require overriding, ignore
3689 primitive_wrappers that correspond to explicit operations that override
3690 an interface primitive.
3691 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
3692 operation to which the class-wide expression applies is a protected op.
3693 with a primitive_wrapper, verify that the updated inherited expression
3694 does not contain an internal call to a protected function. This
3695 completes the implementation of AI12-0166.
3697 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3699 * ali.adb: Document the remaining letters available for ALI lines.
3700 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
3701 * ali.ads: Update type With_Record. Field
3702 Implicit_With_From_Instantiation is no longer in use. Add field
3704 * csinfo.adb (CSinfo): Remove the setup for attribute
3705 Implicit_With_From_Instantiation.
3706 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
3707 either implicitly or explicitly withed.
3708 (Is_Implicit_With_Clause): New routine.
3709 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
3710 confusion with the with clause attribute by the same name.
3711 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
3712 * rtsfind.adb (Maybe_Add_With): Code cleanup.
3713 * sem_ch8.adb (Present_System_Aux): Code cleanup.
3714 * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
3716 (Implicit_With_On_Parent): Mark the with clause as generated for a
3718 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
3719 instantiation are no longer marked as Implicit_With_From_Instantiation
3720 because they are already marked as implicit.
3721 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
3722 which marks implicit with clauses as related to an instantiation.
3723 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
3724 (Parent_With): New routine.
3725 (Set_Implicit_With_From_Instantiation): Removed.
3726 (Set_Parent_With): New routine.
3727 * sinfo.ads: Update the documentation of attribute Implicit_With.
3728 Remove attribute Implicit_With_From_Instantiation along with
3729 occurrences in nodes. Add attribute Parent_With along with occurrences

3736 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3738 * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
3739 entity when the enclosing construct is a body.
3741 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
3743 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
3744 Secondary_Stack_Size handling as a pragma is now generated for the
3745 corresponding aspect instead of an attribute. Pragma expression is
3746 relocated instead of evaluated. Discriminant of the corresponding
3747 record type is referenced rather than the type discriminant.
3748 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
3749 Secondary_Stack_Size rep item checks to only look for the pragma rep.
3750 * sem_ch13.adb (Analyze_One_Aspect): Transform
3751 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
3752 because the attribute does not have visibility on a task type's
3753 discriminants when the type's definition is expanded.
3754 (Analyze_Attribute_Definition_Clause): Remove handling of
3755 Attribute_Secondary_Stack_Size.
3756 * snames.adb-tmpl, snames.ads-tmpl: Remove
3757 Attribute_Secondary_Stack_Size, no longer used.

3763 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3765 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
3766 individual action because the action may denote a complex expression,
3767 such as a case statement, which in turn may contain additional
3770 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3772 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
3773 analysis on a copy of the expression with a copy of the index variable,
3774 because full expansion will rewrite construct into a loop with the
3775 original loop variable.
3776 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
3777 expression is an iterated component association. Full analysis takes
3778 place when construct is rewritten as a loop.
3779 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
3780 is not safe for in-place assignment.
3781 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
3782 entity with no homonym and no other entity in the scope.
3784 2018-01-11 Justin Squirek <squirek@adacore.com>
3786 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
3787 message to be printed on the pragma argument identifier.
3789 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3791 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
3792 entity of the generated invariant procedure in order to construct a
3793 proper entity chain.
3795 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
3797 * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
3800 2018-01-11 Arnaud Charlet <charlet@adacore.com>
3802 * einfo.ads, einfo.adb (Activation_Record_Component,
3803 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
3804 Allow E_Discriminant.
3806 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
3808 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
3809 for atomic access once the component size is taken into account and
3810 also do it if the component type is Atomic or Volatile_Full_Access.
3812 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
3814 * gnatvsn.ads: Bump copyright year.
