322 * freeze.adb (Freeze_Expression): Handle freeze of an entity defined
323 outside of a subprogram body. This case was previously handled during
324 preanalysis; the frozen entities were remembered and left pending until
325 we continued freezeing entities outside of the subprogram. Now, when
326 climbing the parents chain to locate the correct placement for the
327 freezeing node, we check if the entity can be frozen and only when no
328 enclosing node is marked as Must_Not_Freeze the entity is frozen.

340 Its code is basically the previous version of this routine but extended
341 with an additional parameter which is used to specify if during
342 preanalysis we are allowed to freeze entities. If the new parameter is
343 True then the subtree root node is marked as Must_Not_Freeze and no
344 entities are frozen during preanalysis.
345 (Preanalyze_And_Resolve): Invokes the internal version of
346 Preanalyze_And_Resolve without entity freezing.
347 (Preanalyze_With_Freezing_And_Resolve): Invokes the internal version of
348 Prenalyze_And_Resolve with freezing enabled.

382 enclosing scope already handles the secondary stack, take into account
383 transient blocks nested in a block that do not manage the secondary
384 stack and are located within a loop.
386 2018-07-17 Ed Schonberg <schonberg@adacore.com>
388 * sem_util.adb (Enclosing_Subprogram): Protected entries and task
389 entries must be treated separately: task entries are within the

1264 and protected operations.
1266 2018-05-31 Ed Schonberg <schonberg@adacore.com>
1268 * exp_ch4.adb (Expand_Modular_Addition, Expand_Modular_Subtraction):
1269 Convert all operands of the generated code to Standard.Unsigned, to
1270 prevent spurious visibility errors. This is needed when the generated
1271 expansion involves a modular index type of an array type, and the index
1272 type is not immediately visible.

1335 (Start_Search): Modify to use Start_Search_Internal
1336 (Start_Search_Internal): Add to break out an extra flag for searching
1337 case insensative due to the potential for directories within the same
1338 OS to allow different casing schemes.
1339 * sysdep.c (__gnat_name_case_equivalence): Add as a default fallback

1411 2018-05-30 Bob Duff <duff@adacore.com>
1413 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
1414 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
1415 We need to analyze it as part of analyzing the block, so that if the
1416 call to Element that initializes Elmt_Decl returns on the secondary
1417 stack, the block will ss_mark/ss_release. This block is inside the
1418 loop; we don't want to leak memory until the loop exits. The purpose
1419 of analyzing Elmt_Decl first was to catch the error of modifying it,
1420 which is illegal because it's a loop parameter. The above causes us to
1421 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
1422 it on the Element entity, so we end up with an E_Variable node with the
1424 * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.
1425 * sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop
1426 parameter not allowed" error if Is_Loop_Parameter.
1427 * sem_util.adb (Is_Variable): Return False if Is_Loop_Parameter, to
1428 trigger the call to Diagnose_Non_Variable_Lhs.

1433 * sem_eval.adb (Check_Non_Static_Context, Out_Of_Range): Ignore out of
1434 range values for System.Priority in CodePeer mode since the actual
1435 target compiler may provide a wider range.

1442 2018-05-30 Ed Schonberg <schonberg@adacore.com>
1444 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
1445 a package body that is a compilation unit may contain blocks that
1446 declare local subprograms. In Subprogram_Unnesting Mode such
1447 subprograms must be handled as nested inside the (implicit) elaboration
1448 procedure that executes that statement part. To handle properly uplevel
1449 references we construct that subprogram explicitly, to contain blocks
1450 and inner subprograms, The statement part of the compilation unit
1451 becomes a call to this subprogram. This is only done if blocks are
1452 present in the statement list of the body.
1454 2018-05-30 Bob Duff <duff@adacore.com>

1464 for subprogram instantiations to enter callable entity into Subp table.

1471 package to account for the new secondary stack structure. Add types

1523 tagged type. In such case, collecting the list of primitives we may
1524 find two equality primitives: one associated with the untagged private

1758 * exp_unst.adb (Visit_Node): For indexed components and attribute
1759 references, examine index expressions or associated expressions as well
1760 to record uplevel references.
1761 (Vist_Node): For function and procedure calls, if a formal is an
1762 unconstrained array and the actual is constrained, check whether bounds
1763 of actual have uplevel references.
1765 2018-05-28 Ed Schonberg <schonberg@adacore.com>

1780 * exp_unst.adb (Check_Static_Type): For a record subtype, check
1781 discriminant constraints as well.

1783 done for indexed components and slices.
1785 2018-05-28 Javier Miranda <miranda@adacore.com>
1787 * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
1788 value when converting a float value to a fixed-point value. This is
1789 required for CCG because it handles fixed-point types by means of
1790 unsigned integer type variables. The range check is now performed using
1791 the integer value stored in this temporary.
1793 2018-05-28 Yannick Moy <moy@adacore.com>

1817 base type, except for the case where the bounds of the type depend on a
1820 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1822 * einfo.ads, einfo.adb (Needs_Activation_Record): New flag on
1823 access-to-subprogram types, to indicate that an indirect call through
1824 such a type requires an activation record when compiling for LLVM.
1825 * sem_ch3.adb (Access_Subprogram_Declaration): Set new flag as needed.
1827 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1829 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
1830 when bounds of fixed type are static, to remove some spuerfluous
1831 implicit conversions and provide an accurate result when converting
1832 back and forth between the fixed point type and a floating point type.

1839 2018-05-28 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
1841 * exp_unst.adb (Check_Static_Type): Add argument to indicate node to be
1842 replaced, if any; all callers changed.
1843 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
1844 constant with private view so we take the address of that entity.
1845 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
1846 any; all callers changed. Handle N_Indexed_Component like
1847 N_Attribute_Reference. Add N_Type_Conversion case.
1848 (Visit_Node): Indexed references can be uplevel if the type isn't
1850 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
1851 been relocated, set first_named pointer in original node as well.
1853 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1855 * exp_aggr.adb (Flatten): Copy tree of expression in a component
1856 association with a range or a set of discrete choices, rather than
1857 relocating the node. This avoids inconsistencies in the tree when
1858 handling nested subprograms with uplevel references for LLVM.

1924 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
1925 includes a call to function to which it applies. This may mean an
1926 omission of an attribute reference 'Result, in particular if the
1927 function is pqrameterless.
1929 2018-05-28 Justin Squirek <squirek@adacore.com>

1943 * repinfo.adb (List_Array_Info): Start with an explicit blank line and
1944 end with the linker section, if any.
1945 (List_Entities): Do not output the linker section for record types,
1946 array types and variables.
1947 (Print_Expr): Factor out common processing for unary operators and
1948 special values. Adjust and reorder the various cases.
1949 (List_Object_Info): End with the linker section, if any.
1950 (List_Record_Info): Likewise.
1951 (List_Type_Info): Do not start with a blank line.
1953 2018-05-25 Nicolas Roche <roche@adacore.com>
1955 * libgnat/s-valrea.adb (Scan_Real): Abort computation once it is sure
1956 that the result will be either -infinite or +infinite.
1958 2018-05-25 Patrick Bernardi <bernardi@adacore.com>
1960 * libgnat/s-parame.ads, libgnat/s-parame__vxworks.ads,

1962 Expand range of type to match the address space of the target.
1963 (Task_Storage_Size): Remove unused type.
1965 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1967 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
1968 of a fixed point type and the parent is a multiplying operation,
1969 resolve the operand with its own type because the context will impose a
1970 resulting type on the result of the multiplication by means of
1971 approriate conversion.
1973 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1975 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
1976 the in-place initialization aggregate created for pragmas
1977 Initialize_Scalars or Normalize_Scalars is performed with checks
1980 2018-05-25 Arnaud Charlet <charlet@adacore.com>
1982 * exp_aggr.adb (Convert_To_Positional): Bump default for
1983 Max_Others_Replicate to 32. Update comments.

2004 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
2006 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
2007 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
2008 into three distring cases rather than in one loop which attempts to
2009 handle all three cases. This rewrite eliminates an issue where the last
2010 frame of the stack cannot be freed, thus causing the memory range of a
2011 new frame to approach the overflow point of the memory index type.
2012 Since the overflow is logically treated as a
2013 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
2014 (SS_Allocate_Static): New routine. The routine factorizes the static
2015 secondary stack-related code from the former SS_Allocate.
2017 2018-05-25 Sergey Rybin <rybin@adacore.com>
2019 * doc/gnat_ugn/gnat_and_program_execution.rst: Add description of '-U'
2020 option for gnatelim.
2022 2018-05-25 Ed Schonberg <schonberg@adacore.com>
2024 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
2025 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
2026 is created when the proper body of the stub is analyzed.
2027 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
2028 is the proper body of a subunit, the cloned body must be inserted in
2029 the declarative list that contains the stub.
2031 2018-05-25 Justin Squirek <squirek@adacore.com>
2033 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
2034 generate code for 6.5(8-10) so that we don't get an assertion error
2035 when dealing with an incomplete return type.
2037 2018-05-25 Arnaud Charlet <charlet@adacore.com>
2039 * pprint.adb (Expression_Name): Strip too long expressions to avoid
2040 carrying very large strings.

2066 2018-05-25 Ed Schonberg <schonberg@adacore.com>
2068 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
2069 Validate_Derived_Type_Instance, to verify that all interfaces
2070 implemented by the formal type are also implemented by the actual. The
2071 verification is complicated when an interface of the formal is declared
2072 in a generic unit and the actual is declared in an instance of it.
2073 There is currently no mechanism to relate an interface declared within
2074 a generic to the corresponding interface in an instance, so we must

3312 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
3313 delegate the secondary stack management when there is no suitable
3314 transient context, and the transient scope was intended to manage the

3319 the comment on usage.

3547 (Resolve_Actuals): Account for additional cases where finalization
3548 actions are required by utilizing predicate Needs_Finalization rather
3550 (Resolve_Call): Type initialization procedures can now utilize
3551 transient scopes to manage the secondary stack, thus preventing leaks
3552 during initialization. Remove the previous kludgy algorithm which
3553 attempts to manage the secondary stack at the object creation site.
3555 2018-01-11 Jerome Lambourg <lambourg@adacore.com>

3596 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3598 * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
3599 formsl type corresponding to the actual fixed point type is private,
3600 because in this case there can be no suspicious arithmetic operations
3601 in the generic unless they reference a formal subprogram. Clarify
3604 2018-01-11 Javier Miranda <miranda@adacore.com>
3606 * exp_util.adb (Remove_Side_Effects): No action done for functions
3607 returning class-wide types since it requires generating code using
3608 'reference and the CCG target has no secondary stack.
3609 * gnat1drv.adb: Disable building static dispatch tables when generating
3612 2018-01-11 Piotr Trojanek <trojanek@adacore.com>

3618 2018-01-11 Pascal Obry <obry@adacore.com>
3620 * libgnat/s-os_lib.adb (Normalize_Pathname): New implementation.
3622 2018-01-11 Bob Duff <duff@adacore.com>
3624 * doc/gnat_ugn/gnat_utility_programs.rst: Rewrite gnatpp documentation
3625 to match what the Libadalang-based version does.

3628 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3630 * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
3631 if it contains at least one component declaration employing a function
3632 call returning on the secondary stack.
3634 2018-01-11 Yannick Moy <moy@adacore.com>

3649 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3651 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
3652 has a delayed aspect which must be processed at the point the type is
3653 frozen. This mimics what is done when the predicate is provided by a
3656 2018-01-11 Doug Rupp <rupp@adacore.com>
3658 * init.c (vxworks): Add macro checks for __aarch64__.

3669 Default_Sec_Stack_Size.
3670 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack

3676 does not set Default_SS_Size.
3678 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3680 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
3681 legality of an inherited operation that may require overriding, ignore
3682 primitive_wrappers that correspond to explicit operations that override
3683 an interface primitive.
3684 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
3685 operation to which the class-wide expression applies is a protected op.
3686 with a primitive_wrapper, verify that the updated inherited expression
3687 does not contain an internal call to a protected function. This
3688 completes the implementation of AI12-0166.
3690 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3692 * ali.adb: Document the remaining letters available for ALI lines.
3693 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
3694 * ali.ads: Update type With_Record. Field
3695 Implicit_With_From_Instantiation is no longer in use. Add field
3697 * csinfo.adb (CSinfo): Remove the setup for attribute
3698 Implicit_With_From_Instantiation.
3699 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
3700 either implicitly or explicitly withed.
3701 (Is_Implicit_With_Clause): New routine.
3702 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
3703 confusion with the with clause attribute by the same name.
3704 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
3705 * rtsfind.adb (Maybe_Add_With): Code cleanup.
3706 * sem_ch8.adb (Present_System_Aux): Code cleanup.

3709 (Implicit_With_On_Parent): Mark the with clause as generated for a
3711 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
3712 instantiation are no longer marked as Implicit_With_From_Instantiation
3713 because they are already marked as implicit.
3714 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
3715 which marks implicit with clauses as related to an instantiation.
3716 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
3717 (Parent_With): New routine.
3718 (Set_Implicit_With_From_Instantiation): Removed.

3732 entity when the enclosing construct is a body.
3734 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
3736 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
3737 Secondary_Stack_Size handling as a pragma is now generated for the
3738 corresponding aspect instead of an attribute. Pragma expression is
3739 relocated instead of evaluated. Discriminant of the corresponding
3740 record type is referenced rather than the type discriminant.
3741 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
3742 Secondary_Stack_Size rep item checks to only look for the pragma rep.
3743 * sem_ch13.adb (Analyze_One_Aspect): Transform
3744 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
3745 because the attribute does not have visibility on a task type's

3748 Attribute_Secondary_Stack_Size.
3749 * snames.adb-tmpl, snames.ads-tmpl: Remove

3756 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3758 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
3759 individual action because the action may denote a complex expression,
3760 such as a case statement, which in turn may contain additional
3763 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3765 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
3766 analysis on a copy of the expression with a copy of the index variable,
3767 because full expansion will rewrite construct into a loop with the
3768 original loop variable.
3769 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
3770 expression is an iterated component association. Full analysis takes
3771 place when construct is rewritten as a loop.
3772 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
3773 is not safe for in-place assignment.
3774 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
3775 entity with no homonym and no other entity in the scope.
3777 2018-01-11 Justin Squirek <squirek@adacore.com>

3780 message to be printed on the pragma argument identifier.
3782 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3784 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
3785 entity of the generated invariant procedure in order to construct a
3786 proper entity chain.

3795 * einfo.ads, einfo.adb (Activation_Record_Component,
3796 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
3797 Allow E_Discriminant.
3799 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
3801 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
3802 for atomic access once the component size is taken into account and
3803 also do it if the component type is Atomic or Volatile_Full_Access.
3805 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
