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

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

357 * sem_ch3.adb (Preanalyze_Default_Expression): Code adjusted to invoke
358 the new subprogram Preanalyze_With_Freezing_And_Resolve.

360 (Analyze_Expression_Function, Process_Formals): Invoke
361 Preanalyze_Formal_Expression instead of Preanalyze_Spec_Expression

364 class-wide clone for eliminated subprograms.
365 * sem_res.ads, sem_res.adb (Preanalyze_And_Resolve): New subprogram.
366 Its code is basically the previous version of this routine but extended
367 with an additional parameter which is used to specify if during
368 preanalysis we are allowed to freeze entities. If the new parameter is
369 True then the subtree root node is marked as Must_Not_Freeze and no
370 entities are frozen during preanalysis.
371 (Preanalyze_And_Resolve): Invokes the internal version of
372 Preanalyze_And_Resolve without entity freezing.
373 (Preanalyze_With_Freezing_And_Resolve): Invokes the internal version of

408 enclosing scope already handles the secondary stack, take into account
409 transient blocks nested in a block that do not manage the secondary
410 stack and are located within a loop.
412 2018-07-17 Ed Schonberg <schonberg@adacore.com>
414 * sem_util.adb (Enclosing_Subprogram): Protected entries and task
415 entries must be treated separately: task entries are within the

1294 * exp_ch4.adb (Expand_Modular_Addition, Expand_Modular_Subtraction):
1295 Convert all operands of the generated code to Standard.Unsigned, to
1296 prevent spurious visibility errors. This is needed when the generated

1361 (Start_Search): Modify to use Start_Search_Internal
1362 (Start_Search_Internal): Add to break out an extra flag for searching

1437 2018-05-30 Bob Duff <duff@adacore.com>
1439 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
1440 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
1441 We need to analyze it as part of analyzing the block, so that if the
1442 call to Element that initializes Elmt_Decl returns on the secondary
1443 stack, the block will ss_mark/ss_release. This block is inside the
1444 loop; we don't want to leak memory until the loop exits. The purpose
1445 of analyzing Elmt_Decl first was to catch the error of modifying it,
1446 which is illegal because it's a loop parameter. The above causes us to
1447 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
1448 it on the Element entity, so we end up with an E_Variable node with the
1450 * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.
1451 * sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop
1452 parameter not allowed" error if Is_Loop_Parameter.
1453 * sem_util.adb (Is_Variable): Return False if Is_Loop_Parameter, to

1459 * sem_eval.adb (Check_Non_Static_Context, Out_Of_Range): Ignore out of

1461 target compiler may provide a wider range.

1468 2018-05-30 Ed Schonberg <schonberg@adacore.com>
1470 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
1471 a package body that is a compilation unit may contain blocks that
1472 declare local subprograms. In Subprogram_Unnesting Mode such
1473 subprograms must be handled as nested inside the (implicit) elaboration
1474 procedure that executes that statement part. To handle properly uplevel
1475 references we construct that subprogram explicitly, to contain blocks
1476 and inner subprograms, The statement part of the compilation unit
1477 becomes a call to this subprogram. This is only done if blocks are
1478 present in the statement list of the body.
1480 2018-05-30 Bob Duff <duff@adacore.com>

1490 for subprogram instantiations to enter callable entity into Subp table.

1497 package to account for the new secondary stack structure. Add types

1549 tagged type. In such case, collecting the list of primitives we may
1550 find two equality primitives: one associated with the untagged private

1754 To_Mixed): New functions.
1755 * osint.adb: Cleanup: use Is_Directory_Separator, which correctly

1784 * exp_unst.adb (Visit_Node): For indexed components and attribute
1785 references, examine index expressions or associated expressions as well
1786 to record uplevel references.
1787 (Vist_Node): For function and procedure calls, if a formal is an
1788 unconstrained array and the actual is constrained, check whether bounds
1789 of actual have uplevel references.
1791 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1793 * einfo.ads, einfo.adb: Exceptions can be uplevel references, and thus
1794 they can appear as components of activation records.

1804 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1806 * exp_unst.adb (Check_Static_Type): For a record subtype, check
1807 discriminant constraints as well.
1808 (Visit_Node): For a selected component, check type of prefix, as is
1809 done for indexed components and slices.
1811 2018-05-28 Javier Miranda <miranda@adacore.com>
1813 * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
1814 value when converting a float value to a fixed-point value. This is
1815 required for CCG because it handles fixed-point types by means of
1816 unsigned integer type variables. The range check is now performed using
1817 the integer value stored in this temporary.
1819 2018-05-28 Yannick Moy <moy@adacore.com>
1821 * sem_util.adb (Is_OK_Volatile_Context): Add attributes First, Last and

1841 * exp_ch4.adb (Expand_Composite_Equality): For a composite (or FP)
1842 component type, do not expand array equality using the unconstrained
1843 base type, except for the case where the bounds of the type depend on a
1846 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1848 * einfo.ads, einfo.adb (Needs_Activation_Record): New flag on
1849 access-to-subprogram types, to indicate that an indirect call through
1850 such a type requires an activation record when compiling for LLVM.
1851 * sem_ch3.adb (Access_Subprogram_Declaration): Set new flag as needed.
1853 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1855 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
1856 when bounds of fixed type are static, to remove some spuerfluous
1857 implicit conversions and provide an accurate result when converting
1858 back and forth between the fixed point type and a floating point type.

1862 * exp_unst.adb (Unnest_Subprogram): Prevent creation of empty
1865 2018-05-28 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
1867 * exp_unst.adb (Check_Static_Type): Add argument to indicate node to be
1868 replaced, if any; all callers changed.
1869 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
1870 constant with private view so we take the address of that entity.
1871 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
1872 any; all callers changed. Handle N_Indexed_Component like
1873 N_Attribute_Reference. Add N_Type_Conversion case.
1874 (Visit_Node): Indexed references can be uplevel if the type isn't
1876 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
1877 been relocated, set first_named pointer in original node as well.
1879 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1881 * exp_aggr.adb (Flatten): Copy tree of expression in a component
1882 association with a range or a set of discrete choices, rather than
1883 relocating the node. This avoids inconsistencies in the tree when
1884 handling nested subprograms with uplevel references for LLVM.

1939 * sem_prag.adb (Process_Atomic_Independent_Shared_Volatile): Include
1940 the declarations of single concurrent types because they fall in the
1941 category of full type and object declarations.
1943 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
1945 * repinfo.adb (Compute_Max_Length): Skip _Parent component.

1948 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1950 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
1951 includes a call to function to which it applies. This may mean an
1952 omission of an attribute reference 'Result, in particular if the
1953 function is pqrameterless.
1955 2018-05-28 Justin Squirek <squirek@adacore.com>
1957 * sem_ch8.adb (Find_Expanded_Name): Add extra guard to make sure the

1969 * repinfo.adb (List_Array_Info): Start with an explicit blank line and
1970 end with the linker section, if any.
1971 (List_Entities): Do not output the linker section for record types,
1972 array types and variables.
1973 (Print_Expr): Factor out common processing for unary operators and
1974 special values. Adjust and reorder the various cases.
1975 (List_Object_Info): End with the linker section, if any.
1976 (List_Record_Info): Likewise.
1977 (List_Type_Info): Do not start with a blank line.
1979 2018-05-25 Nicolas Roche <roche@adacore.com>
1981 * libgnat/s-valrea.adb (Scan_Real): Abort computation once it is sure
1982 that the result will be either -infinite or +infinite.
1984 2018-05-25 Patrick Bernardi <bernardi@adacore.com>
1986 * libgnat/s-parame.ads, libgnat/s-parame__vxworks.ads,
1987 libgnat/s-parame__ae653.ads, libgnat/s-parame__hpux.ads (Size_Type):
1988 Expand range of type to match the address space of the target.
1989 (Task_Storage_Size): Remove unused type.
1991 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1993 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
1994 of a fixed point type and the parent is a multiplying operation,
1995 resolve the operand with its own type because the context will impose a
1996 resulting type on the result of the multiplication by means of
1997 approriate conversion.
1999 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
2001 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
2002 the in-place initialization aggregate created for pragmas
2003 Initialize_Scalars or Normalize_Scalars is performed with checks
2006 2018-05-25 Arnaud Charlet <charlet@adacore.com>
2008 * exp_aggr.adb (Convert_To_Positional): Bump default for
2009 Max_Others_Replicate to 32. Update comments.
2010 * osint.ads (Unknown_Attributes): No longer pretend this is a constant.
2011 (No_File_Info_Cache): Initialize separately.

2030 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
2032 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
2033 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
2034 into three distring cases rather than in one loop which attempts to
2035 handle all three cases. This rewrite eliminates an issue where the last
2036 frame of the stack cannot be freed, thus causing the memory range of a
2037 new frame to approach the overflow point of the memory index type.
2038 Since the overflow is logically treated as a
2039 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
2040 (SS_Allocate_Static): New routine. The routine factorizes the static
2041 secondary stack-related code from the former SS_Allocate.
2043 2018-05-25 Sergey Rybin <rybin@adacore.com>
2045 * doc/gnat_ugn/gnat_and_program_execution.rst: Add description of '-U'
2046 option for gnatelim.
2048 2018-05-25 Ed Schonberg <schonberg@adacore.com>
2050 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
2051 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
2052 is created when the proper body of the stub is analyzed.
2053 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
2054 is the proper body of a subunit, the cloned body must be inserted in
2055 the declarative list that contains the stub.
2057 2018-05-25 Justin Squirek <squirek@adacore.com>
2059 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
2060 generate code for 6.5(8-10) so that we don't get an assertion error
2061 when dealing with an incomplete return type.
2063 2018-05-25 Arnaud Charlet <charlet@adacore.com>

2094 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
2095 Validate_Derived_Type_Instance, to verify that all interfaces
2096 implemented by the formal type are also implemented by the actual. The

2098 in a generic unit and the actual is declared in an instance of it.
2099 There is currently no mechanism to relate an interface declared within
2100 a generic to the corresponding interface in an instance, so we must
2101 traverse the list of interfaces of the actual, looking for a name
2102 match, and verifying that that interface is declared in an instance.

2671 * sem_ch5.adb (Preanalyze_Range): The pre-analysis of the domain of
2672 iteration of an Ada2012 loop is performed to determine the type of the
2673 domain, but full analysis is performed once the loop is rewritten as a
2674 while-loop during expansion. The pre-analysis suppresses expansion; it
2675 must also suppress the generation of freeze nodes, which may otherwise
2676 appear in the wrong scope before rewritting.

3338 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
3339 delegate the secondary stack management when there is no suitable

3546 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3548 * exp_aggr.adb (Convert_Aggr_In_Object_Decl): Update the call to
3549 Establish_Transient_Scope.
3550 (Convert_To_Assignments): Update the call to Establish_Transient_Scope.
3551 (Expand_Array_Aggregate): Update the call to Establish_Transient_Scope.
3552 * exp_ch6.adb (Expand_Call_Helper): Update the call to
3553 Establish_Transient_Scope.
3554 (Make_Build_In_Place_Call_In_Object_Declaration): Update the call to
3555 Establish_Transient_Scope.
3556 * exp_ch7.adb (Establish_Transient_Scope): Restructured. Delegate the
3557 management of the secondary stack to an enclosing scope if there is no
3558 suitable construct to wrap, and the transient scope was intended to
3559 manage the secondary stack.
3560 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
3561 is a valid boundary for a transient expression which comes from the
3562 statements of the alternative, otherwise alternatives cannot be
3563 wrapped. Assignments of controlled objects which have controlled
3564 actions suppressed now stop the traversal as there is no point in
3565 looking for an enclosing construct. Add several N_xxx_Body choices to
3566 the termination conditions for completeness.
3567 * exp_ch7.ads (Establish_Transient_Scope): Update the parameter profile
3568 and the associated comment on usage.
3569 * exp_smem.adb (Add_Shared_Var_Lock_Procs): Update the call to
3570 Establish_Transient_Scope.
3571 (Add_Write_After): Update the call to Establish_Transient_Scope.
3572 * sem_res.adb (Check_Initialization_Call): Removed.
3573 (Resolve_Actuals): Account for additional cases where finalization
3574 actions are required by utilizing predicate Needs_Finalization rather
3576 (Resolve_Call): Type initialization procedures can now utilize
3577 transient scopes to manage the secondary stack, thus preventing leaks
3578 during initialization. Remove the previous kludgy algorithm which
3579 attempts to manage the secondary stack at the object creation site.
3581 2018-01-11 Jerome Lambourg <lambourg@adacore.com>
3583 * libgnat/g-soliop__qnx.ads: New.

3614 * doc/Makefile: Add Sphinx option -W to treat warnings as errors.
3616 2018-01-11 Ben Brosgol <brosgol@adacore.com>
3618 * doc/gnat_rm/implementation_defined_aspects.rst: Minor type/wording
3620 * gnat_rm.texi: Regenerate.
3622 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3624 * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
3625 formsl type corresponding to the actual fixed point type is private,
3626 because in this case there can be no suspicious arithmetic operations
3627 in the generic unless they reference a formal subprogram. Clarify
3630 2018-01-11 Javier Miranda <miranda@adacore.com>
3632 * exp_util.adb (Remove_Side_Effects): No action done for functions
3633 returning class-wide types since it requires generating code using
3634 'reference and the CCG target has no secondary stack.
3635 * gnat1drv.adb: Disable building static dispatch tables when generating
3638 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
3640 * libgnat/a-direio.ads, libgnat/a-sequio.ads, libgnat/a-ststio.ads,
3641 libgnat/a-textio.ads, libgnat/a-witeio.ads, libgnat/a-ztexio.ads
3642 (File_Type): Add Default_Initial_Condition aspect.
3644 2018-01-11 Pascal Obry <obry@adacore.com>
3646 * libgnat/s-os_lib.adb (Normalize_Pathname): New implementation.
3648 2018-01-11 Bob Duff <duff@adacore.com>
3650 * doc/gnat_ugn/gnat_utility_programs.rst: Rewrite gnatpp documentation
3651 to match what the Libadalang-based version does.
3652 * doc/gnat_ugn/about_this_guide.rst: Update reference.
3654 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3656 * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
3657 if it contains at least one component declaration employing a function
3658 call returning on the secondary stack.
3660 2018-01-11 Yannick Moy <moy@adacore.com>
3662 * doc/gnat_rm/standard_and_implementation_defined_restrictions.rst:
3663 Update description of restriction SPARK_05 with SPARK 2014.

3672 * exp_aggr.adb, exp_ch9.adb, exp_util.adb, sem_aggr.adb, sem_ch3.adb,
3673 sem_res.adb, sem_util.adb: Minor reformatting.
3675 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3677 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
3678 has a delayed aspect which must be processed at the point the type is
3679 frozen. This mimics what is done when the predicate is provided by a
3682 2018-01-11 Doug Rupp <rupp@adacore.com>
3684 * init.c (vxworks): Add macro checks for __aarch64__.
3686 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3688 * exp_util.adb (Add_Failure_Expression): New routine.
3689 (Make_Predicate_Check): Reimplement the handling of Predicate_Failure.
3690 * sem_util.adb (Is_Current_Instance): Code cleanup.
3692 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
3694 * libgnat/s-parame*.adb, libgnat/s-parame*.ads: Remove unneeded
3695 Default_Sec_Stack_Size.
3696 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
3697 limit check so that the integer index does not overflow. Check the
3698 dynamic stack allocation does not cause the secondary stack pointer to
3700 (SS_Info): Align colons.
3701 (SS_Init): Cover the case when bootstraping with an old compiler that
3702 does not set Default_SS_Size.
3704 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3706 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
3707 legality of an inherited operation that may require overriding, ignore
3708 primitive_wrappers that correspond to explicit operations that override
3709 an interface primitive.
3710 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
3711 operation to which the class-wide expression applies is a protected op.
3712 with a primitive_wrapper, verify that the updated inherited expression
3713 does not contain an internal call to a protected function. This
3714 completes the implementation of AI12-0166.
3716 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3718 * ali.adb: Document the remaining letters available for ALI lines.
3719 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
3720 * ali.ads: Update type With_Record. Field
3721 Implicit_With_From_Instantiation is no longer in use. Add field
3723 * csinfo.adb (CSinfo): Remove the setup for attribute
3724 Implicit_With_From_Instantiation.
3725 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
3726 either implicitly or explicitly withed.
3727 (Is_Implicit_With_Clause): New routine.
3728 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
3729 confusion with the with clause attribute by the same name.
3730 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
3731 * rtsfind.adb (Maybe_Add_With): Code cleanup.
3732 * sem_ch8.adb (Present_System_Aux): Code cleanup.
3733 * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
3735 (Implicit_With_On_Parent): Mark the with clause as generated for a
3737 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
3738 instantiation are no longer marked as Implicit_With_From_Instantiation
3739 because they are already marked as implicit.
3740 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
3741 which marks implicit with clauses as related to an instantiation.
3742 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
3743 (Parent_With): New routine.
3744 (Set_Implicit_With_From_Instantiation): Removed.
3745 (Set_Parent_With): New routine.
3746 * sinfo.ads: Update the documentation of attribute Implicit_With.
3747 Remove attribute Implicit_With_From_Instantiation along with
3748 occurrences in nodes. Add attribute Parent_With along with occurrences

3755 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3757 * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
3758 entity when the enclosing construct is a body.
3760 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
3762 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
3763 Secondary_Stack_Size handling as a pragma is now generated for the
3764 corresponding aspect instead of an attribute. Pragma expression is
3765 relocated instead of evaluated. Discriminant of the corresponding
3766 record type is referenced rather than the type discriminant.
3767 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
3768 Secondary_Stack_Size rep item checks to only look for the pragma rep.
3769 * sem_ch13.adb (Analyze_One_Aspect): Transform
3770 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
3771 because the attribute does not have visibility on a task type's
3772 discriminants when the type's definition is expanded.
3773 (Analyze_Attribute_Definition_Clause): Remove handling of
3774 Attribute_Secondary_Stack_Size.
3775 * snames.adb-tmpl, snames.ads-tmpl: Remove
3776 Attribute_Secondary_Stack_Size, no longer used.

3782 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3784 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
3785 individual action because the action may denote a complex expression,
3786 such as a case statement, which in turn may contain additional
3789 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3791 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
3792 analysis on a copy of the expression with a copy of the index variable,
3793 because full expansion will rewrite construct into a loop with the
3794 original loop variable.
3795 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
3796 expression is an iterated component association. Full analysis takes
3797 place when construct is rewritten as a loop.
3798 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
3799 is not safe for in-place assignment.
3800 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
3801 entity with no homonym and no other entity in the scope.
3803 2018-01-11 Justin Squirek <squirek@adacore.com>
3805 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
3806 message to be printed on the pragma argument identifier.
3808 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3810 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
3811 entity of the generated invariant procedure in order to construct a
3812 proper entity chain.
3814 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
3816 * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
3819 2018-01-11 Arnaud Charlet <charlet@adacore.com>
3821 * einfo.ads, einfo.adb (Activation_Record_Component,
3822 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
3823 Allow E_Discriminant.
3825 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
3827 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
3828 for atomic access once the component size is taken into account and
3829 also do it if the component type is Atomic or Volatile_Full_Access.
3831 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
3833 * gnatvsn.ads: Bump copyright year.
