38 checks are generated. If the target is a fixed-point tyoe,
39 generate the required overflow and range checks explicitly,

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

340 outside of a subprogram body. This case was previously handled during
341 preanalysis; the frozen entities were remembered and left pending until
342 we continued freezeing entities outside of the subprogram. Now, when
343 climbing the parents chain to locate the correct placement for the
344 freezeing node, we check if the entity can be frozen and only when no
345 enclosing node is marked as Must_Not_Freeze the entity is frozen.

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

351 (Analyze_Expression_Function, Process_Formals): Invoke
352 Preanalyze_Formal_Expression instead of Preanalyze_Spec_Expression

355 class-wide clone for eliminated subprograms.
356 * sem_res.ads, sem_res.adb (Preanalyze_And_Resolve): New subprogram.
357 Its code is basically the previous version of this routine but extended
358 with an additional parameter which is used to specify if during
359 preanalysis we are allowed to freeze entities. If the new parameter is
360 True then the subtree root node is marked as Must_Not_Freeze and no
361 entities are frozen during preanalysis.
362 (Preanalyze_And_Resolve): Invokes the internal version of
363 Preanalyze_And_Resolve without entity freezing.
364 (Preanalyze_With_Freezing_And_Resolve): Invokes the internal version of

399 enclosing scope already handles the secondary stack, take into account
400 transient blocks nested in a block that do not manage the secondary
401 stack and are located within a loop.
403 2018-07-17 Ed Schonberg <schonberg@adacore.com>
405 * sem_util.adb (Enclosing_Subprogram): Protected entries and task
406 entries must be treated separately: task entries are within the

1285 * exp_ch4.adb (Expand_Modular_Addition, Expand_Modular_Subtraction):
1286 Convert all operands of the generated code to Standard.Unsigned, to
1287 prevent spurious visibility errors. This is needed when the generated

1428 2018-05-30 Bob Duff <duff@adacore.com>
1430 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
1431 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
1432 We need to analyze it as part of analyzing the block, so that if the
1433 call to Element that initializes Elmt_Decl returns on the secondary
1434 stack, the block will ss_mark/ss_release. This block is inside the
1435 loop; we don't want to leak memory until the loop exits. The purpose
1436 of analyzing Elmt_Decl first was to catch the error of modifying it,
1437 which is illegal because it's a loop parameter. The above causes us to
1438 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
1439 it on the Element entity, so we end up with an E_Variable node with the
1441 * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.
1442 * sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop
1443 parameter not allowed" error if Is_Loop_Parameter.
1444 * sem_util.adb (Is_Variable): Return False if Is_Loop_Parameter, to

1459 2018-05-30 Ed Schonberg <schonberg@adacore.com>
1461 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
1462 a package body that is a compilation unit may contain blocks that
1463 declare local subprograms. In Subprogram_Unnesting Mode such
1464 subprograms must be handled as nested inside the (implicit) elaboration
1465 procedure that executes that statement part. To handle properly uplevel
1466 references we construct that subprogram explicitly, to contain blocks
1467 and inner subprograms, The statement part of the compilation unit
1468 becomes a call to this subprogram. This is only done if blocks are
1469 present in the statement list of the body.

1541 find two equality primitives: one associated with the untagged private

1745 To_Mixed): New functions.
1746 * osint.adb: Cleanup: use Is_Directory_Separator, which correctly

1775 * exp_unst.adb (Visit_Node): For indexed components and attribute
1776 references, examine index expressions or associated expressions as well
1777 to record uplevel references.
1778 (Vist_Node): For function and procedure calls, if a formal is an
1779 unconstrained array and the actual is constrained, check whether bounds
1780 of actual have uplevel references.
1782 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1784 * einfo.ads, einfo.adb: Exceptions can be uplevel references, and thus
1785 they can appear as components of activation records.

1792 depends on a discriminant manually instead of using the predicate
1793 Size_Depends_On_Discriminant in the array type case.
1795 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1797 * exp_unst.adb (Check_Static_Type): For a record subtype, check
1798 discriminant constraints as well.
1799 (Visit_Node): For a selected component, check type of prefix, as is
1800 done for indexed components and slices.
1802 2018-05-28 Javier Miranda <miranda@adacore.com>
1804 * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
1805 value when converting a float value to a fixed-point value. This is
1806 required for CCG because it handles fixed-point types by means of
1807 unsigned integer type variables. The range check is now performed using
1808 the integer value stored in this temporary.
1810 2018-05-28 Yannick Moy <moy@adacore.com>
1812 * sem_util.adb (Is_OK_Volatile_Context): Add attributes First, Last and

1832 * exp_ch4.adb (Expand_Composite_Equality): For a composite (or FP)
1833 component type, do not expand array equality using the unconstrained
1834 base type, except for the case where the bounds of the type depend on a
1837 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1839 * einfo.ads, einfo.adb (Needs_Activation_Record): New flag on
1840 access-to-subprogram types, to indicate that an indirect call through
1841 such a type requires an activation record when compiling for LLVM.
1842 * sem_ch3.adb (Access_Subprogram_Declaration): Set new flag as needed.
1844 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1846 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
1847 when bounds of fixed type are static, to remove some spuerfluous
1848 implicit conversions and provide an accurate result when converting
1849 back and forth between the fixed point type and a floating point type.

1853 * exp_unst.adb (Unnest_Subprogram): Prevent creation of empty
1856 2018-05-28 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
1858 * exp_unst.adb (Check_Static_Type): Add argument to indicate node to be
1859 replaced, if any; all callers changed.
1860 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
1861 constant with private view so we take the address of that entity.
1862 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
1863 any; all callers changed. Handle N_Indexed_Component like
1864 N_Attribute_Reference. Add N_Type_Conversion case.
1865 (Visit_Node): Indexed references can be uplevel if the type isn't
1867 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
1868 been relocated, set first_named pointer in original node as well.
1870 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1872 * exp_aggr.adb (Flatten): Copy tree of expression in a component
1873 association with a range or a set of discrete choices, rather than
1874 relocating the node. This avoids inconsistencies in the tree when
1875 handling nested subprograms with uplevel references for LLVM.

1930 * sem_prag.adb (Process_Atomic_Independent_Shared_Volatile): Include
1931 the declarations of single concurrent types because they fall in the
1932 category of full type and object declarations.
1934 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
1936 * repinfo.adb (Compute_Max_Length): Skip _Parent component.

1939 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1941 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
1942 includes a call to function to which it applies. This may mean an
1943 omission of an attribute reference 'Result, in particular if the
1944 function is pqrameterless.
1946 2018-05-28 Justin Squirek <squirek@adacore.com>

1960 * repinfo.adb (List_Array_Info): Start with an explicit blank line and
1961 end with the linker section, if any.
1962 (List_Entities): Do not output the linker section for record types,
1963 array types and variables.
1964 (Print_Expr): Factor out common processing for unary operators and
1965 special values. Adjust and reorder the various cases.
1966 (List_Object_Info): End with the linker section, if any.
1967 (List_Record_Info): Likewise.
1968 (List_Type_Info): Do not start with a blank line.
1970 2018-05-25 Nicolas Roche <roche@adacore.com>
1972 * libgnat/s-valrea.adb (Scan_Real): Abort computation once it is sure
1973 that the result will be either -infinite or +infinite.
1975 2018-05-25 Patrick Bernardi <bernardi@adacore.com>
1977 * libgnat/s-parame.ads, libgnat/s-parame__vxworks.ads,
1978 libgnat/s-parame__ae653.ads, libgnat/s-parame__hpux.ads (Size_Type):
1979 Expand range of type to match the address space of the target.
1980 (Task_Storage_Size): Remove unused type.
1982 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1984 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
1985 of a fixed point type and the parent is a multiplying operation,
1986 resolve the operand with its own type because the context will impose a
1987 resulting type on the result of the multiplication by means of
1988 approriate conversion.
1990 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1992 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
1993 the in-place initialization aggregate created for pragmas
1994 Initialize_Scalars or Normalize_Scalars is performed with checks
1997 2018-05-25 Arnaud Charlet <charlet@adacore.com>
1999 * exp_aggr.adb (Convert_To_Positional): Bump default for
2000 Max_Others_Replicate to 32. Update comments.
2001 * osint.ads (Unknown_Attributes): No longer pretend this is a constant.
2002 (No_File_Info_Cache): Initialize separately.

2021 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
2023 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
2024 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
2025 into three distring cases rather than in one loop which attempts to
2026 handle all three cases. This rewrite eliminates an issue where the last
2027 frame of the stack cannot be freed, thus causing the memory range of a
2028 new frame to approach the overflow point of the memory index type.
2029 Since the overflow is logically treated as a
2030 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
2031 (SS_Allocate_Static): New routine. The routine factorizes the static
2032 secondary stack-related code from the former SS_Allocate.
2034 2018-05-25 Sergey Rybin <rybin@adacore.com>
2036 * doc/gnat_ugn/gnat_and_program_execution.rst: Add description of '-U'
2037 option for gnatelim.

2041 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
2042 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
2043 is created when the proper body of the stub is analyzed.
2044 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
2045 is the proper body of a subunit, the cloned body must be inserted in
2046 the declarative list that contains the stub.
2048 2018-05-25 Justin Squirek <squirek@adacore.com>
2050 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
2051 generate code for 6.5(8-10) so that we don't get an assertion error
2052 when dealing with an incomplete return type.
2054 2018-05-25 Arnaud Charlet <charlet@adacore.com>
2056 * pprint.adb (Expression_Name): Strip too long expressions to avoid
2057 carrying very large strings.

2085 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
2086 Validate_Derived_Type_Instance, to verify that all interfaces
2087 implemented by the formal type are also implemented by the actual. The
2088 verification is complicated when an interface of the formal is declared
2089 in a generic unit and the actual is declared in an instance of it.
2090 There is currently no mechanism to relate an interface declared within
2091 a generic to the corresponding interface in an instance, so we must
2092 traverse the list of interfaces of the actual, looking for a name
2093 match, and verifying that that interface is declared in an instance.

3329 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
3330 delegate the secondary stack management when there is no suitable

3545 (Make_Build_In_Place_Call_In_Object_Declaration): Update the call to
3546 Establish_Transient_Scope.
3547 * exp_ch7.adb (Establish_Transient_Scope): Restructured. Delegate the
3548 management of the secondary stack to an enclosing scope if there is no
3549 suitable construct to wrap, and the transient scope was intended to
3550 manage the secondary stack.
3551 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
3552 is a valid boundary for a transient expression which comes from the
3553 statements of the alternative, otherwise alternatives cannot be
3554 wrapped. Assignments of controlled objects which have controlled
3555 actions suppressed now stop the traversal as there is no point in
3556 looking for an enclosing construct. Add several N_xxx_Body choices to
3557 the termination conditions for completeness.
3558 * exp_ch7.ads (Establish_Transient_Scope): Update the parameter profile
3559 and the associated comment on usage.
3560 * exp_smem.adb (Add_Shared_Var_Lock_Procs): Update the call to
3561 Establish_Transient_Scope.
3562 (Add_Write_After): Update the call to Establish_Transient_Scope.
3563 * sem_res.adb (Check_Initialization_Call): Removed.
3564 (Resolve_Actuals): Account for additional cases where finalization
3565 actions are required by utilizing predicate Needs_Finalization rather
3567 (Resolve_Call): Type initialization procedures can now utilize
3568 transient scopes to manage the secondary stack, thus preventing leaks
3569 during initialization. Remove the previous kludgy algorithm which
3570 attempts to manage the secondary stack at the object creation site.
3572 2018-01-11 Jerome Lambourg <lambourg@adacore.com>
3574 * libgnat/g-soliop__qnx.ads: New.

3611 * gnat_rm.texi: Regenerate.
3613 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3615 * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
3616 formsl type corresponding to the actual fixed point type is private,
3617 because in this case there can be no suspicious arithmetic operations
3618 in the generic unless they reference a formal subprogram. Clarify
3621 2018-01-11 Javier Miranda <miranda@adacore.com>
3623 * exp_util.adb (Remove_Side_Effects): No action done for functions
3624 returning class-wide types since it requires generating code using
3625 'reference and the CCG target has no secondary stack.
3626 * gnat1drv.adb: Disable building static dispatch tables when generating
3629 2018-01-11 Piotr Trojanek <trojanek@adacore.com>

3633 (File_Type): Add Default_Initial_Condition aspect.
3635 2018-01-11 Pascal Obry <obry@adacore.com>
3637 * libgnat/s-os_lib.adb (Normalize_Pathname): New implementation.
3639 2018-01-11 Bob Duff <duff@adacore.com>
3641 * doc/gnat_ugn/gnat_utility_programs.rst: Rewrite gnatpp documentation
3642 to match what the Libadalang-based version does.
3643 * doc/gnat_ugn/about_this_guide.rst: Update reference.
3645 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3647 * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
3648 if it contains at least one component declaration employing a function
3649 call returning on the secondary stack.
3651 2018-01-11 Yannick Moy <moy@adacore.com>
3653 * doc/gnat_rm/standard_and_implementation_defined_restrictions.rst:
3654 Update description of restriction SPARK_05 with SPARK 2014.

3663 * exp_aggr.adb, exp_ch9.adb, exp_util.adb, sem_aggr.adb, sem_ch3.adb,
3664 sem_res.adb, sem_util.adb: Minor reformatting.
3666 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3668 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
3669 has a delayed aspect which must be processed at the point the type is
3670 frozen. This mimics what is done when the predicate is provided by a
3673 2018-01-11 Doug Rupp <rupp@adacore.com>
3675 * init.c (vxworks): Add macro checks for __aarch64__.
3677 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3679 * exp_util.adb (Add_Failure_Expression): New routine.

3681 * sem_util.adb (Is_Current_Instance): Code cleanup.
3683 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
3685 * libgnat/s-parame*.adb, libgnat/s-parame*.ads: Remove unneeded
3686 Default_Sec_Stack_Size.
3687 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
3688 limit check so that the integer index does not overflow. Check the
3689 dynamic stack allocation does not cause the secondary stack pointer to
3691 (SS_Info): Align colons.
3692 (SS_Init): Cover the case when bootstraping with an old compiler that
3693 does not set Default_SS_Size.
3695 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3697 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
3698 legality of an inherited operation that may require overriding, ignore
3699 primitive_wrappers that correspond to explicit operations that override
3700 an interface primitive.
3701 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
3702 operation to which the class-wide expression applies is a protected op.
3703 with a primitive_wrapper, verify that the updated inherited expression
3704 does not contain an internal call to a protected function. This
3705 completes the implementation of AI12-0166.
3707 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3709 * ali.adb: Document the remaining letters available for ALI lines.
3710 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
3711 * ali.ads: Update type With_Record. Field
3712 Implicit_With_From_Instantiation is no longer in use. Add field
3714 * csinfo.adb (CSinfo): Remove the setup for attribute
3715 Implicit_With_From_Instantiation.
3716 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
3717 either implicitly or explicitly withed.
3718 (Is_Implicit_With_Clause): New routine.
3719 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
3720 confusion with the with clause attribute by the same name.
3721 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
3722 * rtsfind.adb (Maybe_Add_With): Code cleanup.
3723 * sem_ch8.adb (Present_System_Aux): Code cleanup.
3724 * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
3726 (Implicit_With_On_Parent): Mark the with clause as generated for a
3728 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
3729 instantiation are no longer marked as Implicit_With_From_Instantiation
3730 because they are already marked as implicit.
3731 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
3732 which marks implicit with clauses as related to an instantiation.
3733 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
3734 (Parent_With): New routine.
3735 (Set_Implicit_With_From_Instantiation): Removed.
3736 (Set_Parent_With): New routine.
3737 * sinfo.ads: Update the documentation of attribute Implicit_With.
3738 Remove attribute Implicit_With_From_Instantiation along with
3739 occurrences in nodes. Add attribute Parent_With along with occurrences

3746 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3748 * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
3749 entity when the enclosing construct is a body.
3751 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
3753 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
3754 Secondary_Stack_Size handling as a pragma is now generated for the
3755 corresponding aspect instead of an attribute. Pragma expression is
3756 relocated instead of evaluated. Discriminant of the corresponding
3757 record type is referenced rather than the type discriminant.
3758 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
3759 Secondary_Stack_Size rep item checks to only look for the pragma rep.
3760 * sem_ch13.adb (Analyze_One_Aspect): Transform
3761 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
3762 because the attribute does not have visibility on a task type's
3763 discriminants when the type's definition is expanded.
3764 (Analyze_Attribute_Definition_Clause): Remove handling of
3765 Attribute_Secondary_Stack_Size.
3766 * snames.adb-tmpl, snames.ads-tmpl: Remove
3767 Attribute_Secondary_Stack_Size, no longer used.
3769 2018-01-11 Justin Squirek <squirek@adacore.com>

3773 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3775 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
3776 individual action because the action may denote a complex expression,
3777 such as a case statement, which in turn may contain additional
3780 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3782 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
3783 analysis on a copy of the expression with a copy of the index variable,
3784 because full expansion will rewrite construct into a loop with the
3785 original loop variable.
3786 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
3787 expression is an iterated component association. Full analysis takes
3788 place when construct is rewritten as a loop.
3789 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
3790 is not safe for in-place assignment.
3791 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
3792 entity with no homonym and no other entity in the scope.
3794 2018-01-11 Justin Squirek <squirek@adacore.com>
3796 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
3797 message to be printed on the pragma argument identifier.
3799 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3801 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
3802 entity of the generated invariant procedure in order to construct a
3803 proper entity chain.
3805 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
3807 * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
3810 2018-01-11 Arnaud Charlet <charlet@adacore.com>
3812 * einfo.ads, einfo.adb (Activation_Record_Component,
3813 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
3814 Allow E_Discriminant.
3816 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
3818 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
3819 for atomic access once the component size is taken into account and
3820 also do it if the component type is Atomic or Volatile_Full_Access.
3822 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
3824 * gnatvsn.ads: Bump copyright year.
