238 * exp_ch6.adb (Expand_Call_Helper): When locating the
239 accessibility entity created for an access parameter, handle
240 properly a reference to a formal of an enclosing subprogram. if
241 the reference appears in an inherited class-wide condition, it
242 is the rewriting of the reference in the ancestor expression,
243 but the accessibility entity must be that of the current formal.

247 * exp_ch4.adb (Expand_Non_Binary_Modular_Op): New subprogram.

280 2017-05-02 Ed Schonberg <schonberg@adacore.com>
282 * exp_ch3.adb (Freeze_Type): Do not generate an invariant
283 procedure body for a local (sub)type declaration within a
284 predicate function. Invariant checks do not apply to these, and
285 the expansion of the procedure will happen in the wrong scope,
286 leading to misplaced freeze nodes.
288 2017-05-02 Ed Schonberg <schonberg@adacore.com>
290 * exp_util.adb (Insert_Library_Level_Action): Use proper scope
291 to analyze generated actions. If the main unit is a body,
292 the required scope is that of the corresponding unit declaration.
294 2017-05-02 Arnaud Charlet <charlet@adacore.com>
296 * einfo.adb (Declaration_Node): flip branches of
297 an IF statement to avoid repeated negations in its condition;

327 * exp_disp.adb (Set_All_DT_Position, In_Predef_Prim_DT):
328 Refine predicate for the case where the primitive operation
329 is a renaming of equality. An overriding operation that is
330 a user-defined renaming of predefined equality inherits its
331 slot from the overridden operation. Otherwise it is treated
332 as a predefined op and occupies the same predefined slot as
333 equality. A call to it is transformed into a call to its alias,
334 which is the predefined equality. A dispatching call thus uses
335 the proper slot if operation is further inherited and called
336 with class-wide arguments.
338 2017-05-02 Justin Squirek <squirek@adacore.com>
340 * errout.adb (Set_Msg_Text): Add a case to switch the message

374 statement if the initialization call is a null procedure, as
375 can happen with a controlled type with no explicit Initialize
376 procedure, or an array of such.
377 * exp_ch7.adb (Process_Object_Declaration): For a type with
378 controlled components that has a trivial Initialize procedure,
379 insert declaration for finalization counter after object

382 finalization block and attendant declarations if component has
383 a trivial Initialize procedure.

385 a trivial Initialize procedure.

415 2017-05-02 Gary Dismukes <dismukes@adacore.com>
417 * checks.ads (Null_Exclusion_Static_Checks): Add Boolean
418 parameter Array_Comp to indicate the case of an array object
419 with null-excluding components.
420 * checks.adb (Null_Exclusion_Static_Checks):
421 Call Compile_Time_Constraint_Error instead of
422 Apply_Compile_Time_Constraint_Error in the component case. Also
423 call that when Array_Comp is True, with an appropriate warning for
424 the array component case. Only create an explicit initialization
425 by null in the case of an object of a null-excluding access type
426 (and no longer do that in the component case).
427 * sem_ch3.adb (Check_Component): Add a Boolean parameter
428 Array_Comp defaulted to False. Pass Empty for the Comp
429 actual when calling Null_Exclusion_Static_Checks in the case
430 where Comp_Decl matches Object_Decl, because we don't have a
431 component in that case. In the case of an object or component
432 of an array type, pass True for Array_Comp on the recursive call

437 * s-taprop-linux.adb (Prio_To_Linux_Prio): New function to correctly
438 compute the linux priority from the Ada priority. Call this everywhere
439 required. In particular, the previous version was not doing this
440 computation when setting the ceiling priority in various places. It
441 was just converting to C.int, which results in a ceiling that is off

462 * exp_ch9.adb (Discriminated_Size): Moved to sem_util.
463 * sem_util.ads, sem_util.adb (Discriminated_Size): Predicate moved
464 here from exp_ch9, to recognize objects whose creation requires
465 dynamic allocation, so that the proper warning can be emitted
466 when restriction No_Implicit_Heap_Allocation is in effect.
467 * sem_ch3.adb (Analyze_Object_Declaration): Use Discriminated_Size
468 to emit proper warning when an object that requires dynamic

541 divisions by constants whenever possible, as an optimization
542 for restricted targets.

546 * checks.adb, sem_ch3.adb, sem_ch6.adb: Minor reformatting.
548 2017-05-02 Bob Duff <duff@adacore.com>
550 * exp_attr.adb (Callable, Identity, Terminated): Use Find_Prim_Op
551 to find primitive ops, instead of using an Identifier that will
552 later be looked up. This is necessary because these ops are not
553 necessarily visible at all places where we need to call them.
554 * exp_util.ads: Minor comment fix.
556 2017-05-02 Ed Schonberg <schonberg@adacore.com>
558 * sem_ch6.adb (Fully_Conformant_Expressions): Two entity
559 references are fully conformant if they are both expansions
560 of the discriminant of a protected type, within one of the
561 protected operations. One occurrence may be expanded into a
562 constant declaration while the other is an input parameter to
563 the corresponding generated subprogram.

610 happens to cancel itself.
612 2017-04-28 Ed Schonberg <schonberg@adacore.com>
614 * sem_ch4.adb (Complete_Object_Operation): When rewriting the
615 controlling actual in a prefixed call, preserve the original node
616 information if the prefix itself has been rewritten, for ASIS use.
618 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
620 * exp_ch6.adb (Insert_Post_Call_Actions):
621 Code clean up. Insert the post-call actions after an enclosing
622 procedure call when N denotes a function call and appears as an
623 actual parameter in the procedure call.

627 * freeze.adb (Check_Component_Storage_Order): If there is a clause
628 for the component, also reject the attribute if the component
629 doesn't end on a byte boundary and its scalar storage order is
630 different from that of the enclosing record type.
632 2017-04-28 Javier Miranda <miranda@adacore.com>

666 * sem_util.ads, sem_util.adb (Might_Raise): New function
667 that replaces Is_Exception_Safe, but has the opposite
668 sense. Is_Exception_Safe was missing various cases -- calls inside
669 a pragma Debug, calls inside an 'if' or assignment statement,
670 etc. Might_Raise now walks the entire subtree looking for things
672 * exp_ch9.adb (Is_Exception_Safe): Remove.
673 (Build_Protected_Subprogram_Body): Replace call to
674 Is_Exception_Safe with "not Might_Raise". Misc cleanup (use
675 constants where possible).
676 * exp_ch7.adb: Rename Is_Protected_Body -->
677 Is_Protected_Subp_Body. A protected_body is something different

706 * sem_ch13.adb (Analyze_Aspect_Specifications, case
707 Interrupt_Handler and Attach_Handler): Generate reference
708 to protected operation to prevent spurious warnings about

714 * sem_prag.adb (Relocate_Pragmas_To_Body): A pragma Warnings
715 that follows an expression function must not be relocated to
716 the generated body, because it applies to the code that follows.
718 2017-04-28 Gary Dismukes <dismukes@adacore.com>
720 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): Test
721 Relaxed_RM_Semantics to avoid having CodePeer issue errors on
722 code that might violate the more stringent checking for 'Access
723 introduced in Ada 2005.
725 2017-04-28 Arnaud Charlet <charlet@adacore.com>
727 * a-cforse.adb: minor style fix in comment.
729 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>

747 * sem_ch6.adb (Freeze_Type_Refs): For an interface conversion
748 node between access types, freeze the designated type as well,
749 so that dispatch table pointers are created in the proper scope,
750 and not in the constructed body of the expression function.
752 2017-04-28 Bob Duff <duff@adacore.com>
754 * alloc.ads (Nodes_Initial): Go back to previous value. The large
755 value makes large compilations faster, but small compilations slower.
757 2017-04-28 Arnaud Charlet <charlet@adacore.com>
759 * sem_util.adb: minor typos in Is_Child_Or_Sibling.
761 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
763 * erroutc.adb (Compilation_Errors): Do not consider info messages

777 2017-04-28 Ed Schonberg <schonberg@adacore.com>
779 * sem_res.adb (In_Instance_Code): New predicate in
780 Valid_Conversion, to determine whether a type conversion appears
781 as (or within) an actual for a formal object. Type conversions
782 in instances are not rechecked in Valid_Conversion because
783 visibility changes between generic location andi instance may
784 lead to spurious errors, but conversions within an actual must be
785 fully checked, and they are not fully resolved when pre-analyzing
788 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
790 * exp_ch6.adb (Expand_N_Extended_Return_Statement): Use
791 New_Copy_Tree instead of Relocate_Node as any subsequent copies
792 of the relocated node will have mangled Parent pointers.
793 * sem_util.adb (Build_NCT_Hash_Tables): Reset both hash
794 tables used in conjunction with entity and itype replication.
795 (Visit_Entity): Rewrite the restriction on which entities

834 components_to_record.
835 (gnu_field_to_gnat): New function.
836 (warn_on_field_placement): Likewise.
837 (components_to_record): Add GNAT_RECORD_TYPE and remove REORDER
838 parameters. Rename local variables and adjust recursive call.

850 For efficiency, cache results of Is_Internal_File_Name and
851 Is_Predefined_File_Name in the Units table. This avoids a lot
852 of repeated text processing.
854 2017-04-27 Emmanuel Briot <briot@adacore.com>
856 * g-comlin.adb (Sort_Sections): remove useless test.
858 2017-04-27 Claire Dross <dross@adacore.com>

861 allow the use of regular equality over elements in contracts.
862 (Formal_Model): Ghost package containing model functions that are
863 used in subprogram contracts.
864 (Current_To_Last): Removed, model functions should be used instead.
865 (First_To_Previous): Removed, model functions should be used instead.
866 (Strict_Equal): Removed, model functions should be used instead.
867 (No_Overlap): Removed, model functions should be used instead.
868 (Equivalent_Keys): Functions over cursors are removed. They were

883 2017-04-27 Ed Schonberg <schonberg@adacore.com>
885 * exp_util.adb (Replace_Entity): The prefix of a 'Result
886 attribute reference in a post- condition is the subprogram to
887 which the condition applies. If the condition is inherited
888 by a type extension, the prefix becomes a reference to the
889 inherited operation, but there is no need to create a wrapper
890 for this operation, because 'Result is expanded independently
891 when elaborating the postconditions.
893 2017-04-27 Bob Duff <duff@adacore.com>
895 * sinput.adb: Minor code cleanup.
896 * namet.adb (Append): Create faster versions of
897 Append(String) and Append(Name_Id) by using slice assignment
899 * sem_util.adb (In_Instance): Speed this up by removing
900 unnecessary tests; Is_Generic_Instance is defined for all
902 * sem_util.ads, sem_util.adb (In_Parameter_Specification):
903 Remove unused function.
904 * alloc.ads (Nodes_Initial): Use a much larger value, because
905 the compiler was spending a lot of time copying the nodes table
906 when it grows. This number was chosen in 1996, so is rather out
907 of date with current memory sizes. Anyway, it's virtual memory.
908 Get rid of Orig_Nodes_...; use Node_... instead.
909 * atree.adb (Lock): Do not release the Nodes tables; it's a
911 Orig_Nodes_ ==> Nodes_
912 * nlists.adb: Orig_Nodes_ ==> Nodes_
913 * g-table.adb: Remove unused "with" clause.
914 * g-table.ads, table.ads: Remove Big_Table_Type, which should
915 not be used by clients.

957 of Expand_Dispatching_Call. If the denoted subprogram has a
958 class-wide precondition, this is the only precondition that
959 applies to the call, rather that the class-wide preconditions
960 that may apply to the body that is executed. (This is specified

971 * sem_prag.adb (Inherit_Class_Wide_Pre): If the parent operation
972 is itself inherited it does not carry any contract information,
973 so examine its parent operation which is its Alias.

977 * sem_attr.adb (Analyze_Attribute, case 'Image): In Ada2012 the
978 prefix can be an object reference in which case Obj'Image (X)
979 can only be interpreted as an indexing of the parameterless
980 version of the attribute.
981 * par-ch4.adb (P_Name): An attribute reference can be the prefix of
982 an indexing or a slice operation if the attribute does not require
983 parameters. In Ada2012 'Image also belongs in this category,
984 and A'Image (lo .. hi) is legal and must be parsed as a slice.
986 2017-04-27 Yannick Moy <moy@adacore.com>
988 * exp_ch4.adb: Minor reformatting.
989 * gnat1drv.adb (Adjust_Global_Switches): When in GNATprove mode,

1542 * a-cofuba.ads, a-cofuma.ads, a-cofuse.ads, a-cofuve.ads Reformat
1543 to improve readablity. Subprograms are separated between basic
1544 operations, constructors and properties. Universally quantified
1545 formulas in contracts are factorized in independant functions
1546 with a name and a comment. Names of parameters are improved.
1548 2017-04-27 Gary Dismukes <dismukes@adacore.com>
1550 * exp_spark.adb, sem_elab.adb: Minor reformatting and typo fix.
1552 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
1554 * sem_res.adb (Resolve_Type_Conversion): Do not
1555 install a predicate check here since this is already done during
1556 the expansion phase. Verify whether the operand satisfies the
1557 static predicate (if any) of the target type.
1558 * sem_ch3.adb (Analyze_Object_Declaration): Do
1559 not install a predicate check if the object is initialized by
1560 means of a type conversion because the conversion is subjected
1563 2017-04-27 Tristan Gingold <gingold@adacore.com>
1565 * a-except.ads, a-except.adb, a-exexpr.adb: Removed (will be

1577 s-excmac-arm.ads, s-excmac-arm.adb (New_Occurrence): Rewrite it in
1580 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
1582 * exp_ch7.adb (Establish_Transient_Scope): Rewrite
1583 the loop which detects potential enclosing transient scopes. The
1584 loop now terminates much earlier as transient scopes are bounded
1585 by packages and subprograms.
1587 2017-04-27 Claire Dross <dross@adacore.com>
1589 * a-cfdlli.adb, a-cfdlli.ads (=): Generic parameter removed to
1590 allow the use of regular equality over elements in contracts.
1591 (Cursor): Type is now public so that it can be used in
1593 (Formal_Model): Ghost package containing
1594 model functions that are used in subprogram contracts.
1595 (Current_To_Last): Removed, model functions should be used
1597 (First_To_Previous): Removed, model functions should
1599 (Strict_Equal): Removed, model functions
1600 should be used instead.
1601 (Append): Default parameter value
1602 replaced by new wrapper to allow more precise contracts.
1603 (Insert): Default parameter value replaced by new wrapper to
1604 allow more precise contracts.
1605 (Delete): Default parameter
1606 value replaced by new wrapper to allow more precise contracts.
1607 (Prepend): Default parameter value replaced by new wrapper to
1608 allow more precise contracts.
1609 (Delete_First): Default parameter
1610 value replaced by new wrapper to allow more precise contracts.
1611 (Delete_Last): Default parameter value replaced by new wrapper

1620 Default_Initial_Condition procedure of a type under the SPARK
1621 elaboration checks umbrella.
1623 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>

1632 * adaint.c (__gnat_get_current_dir): Return 0 in length if
1634 * a-direct.adb, g-dirope.adb, osint.adb, s-os_lib.adb: Raise
1635 exception if getcwd failed.

1644 * debug.adb Change the documentation of switch -gnatd.s.
1645 * exp_ch7.adb (Make_Transient_Block): Transient blocks do not need
1646 to manage the secondary stack when an enclosing scope already
1647 performs this functionality (aka relaxed management). Switch
1648 -gnatd.s may be used to force strict management in which case
1649 the block will manage the secondary stack unconditionally. Add
1650 a guard to stop the traversal when encountering a package or a
1653 2017-04-27 Ed Schonberg <schonberg@adacore.com>
1655 * sem_res.adb (Resolve_Call): Refine further the handling of
1656 limited views of return types in function calls. If the function
1657 that returns a limited view appears in the current unit,
1658 we do not replace its type by the non-limited view because
1659 this transformation is performed int the back-end. However,
1660 the type of the call itself must be the non-limited view, to
1661 prevent spurious resolution errors.
1663 2017-04-27 Ed Schonberg <schonberg@adacore.com>
1665 * einfo,ads, einfo.adb (Class_Wide_Preconds, Class_Wide_Postconds):
1666 Removed, proposed implementation using generics for class-wide
1667 preconditions proved impractical.
1668 (Class_Wide_Clone): New attribute of subprogram. Designates
1669 subprogram created for primitive operations with class-wide
1670 pre/postconditions that contain calls to other primitives. The
1671 clone holds the body of the original primitive, but the
1672 pre/postonditions do not apply to it. The original body is
1673 rewritten as a wrapper for a call to the clone.
1674 (Is_Class_Wide_Clone): New flag to identify a Class_Wide_Clone. If
1675 the flag is set, no code for the corresponding pre/postconditions
1676 is inserted into its body.
1678 2017-04-27 Bob Duff <duff@adacore.com>
1680 * exp_prag.adb, par-prag.adb, sem_ch13.adb: Ignore

1724 private child of Ada.Containers used to implement all functional
1726 * a-cofuma.ads, a-cofuma.adb (Ada.Containers.Functional_Maps): New
1727 child of Ada.Containers. It provides functional indefinite unbounded
1728 maps which can be used as high level models for specification
1730 * a-cofuse.ads, a-cofuse.adb (Ada.Containers.Functional_Sets): New
1731 child of Ada.Containers. It provides functional indefinite unbounded
1732 sets which can be used as high level models for specification
1734 * a-cofuve.ads, a-cofuve.adb (Ada.Containers.Functional_Vectors): New
1735 child of Ada.Containers. It provides functional indefinite unbounded
1736 vectors which can be used as high level models for specification

1745 2017-04-27 Ed Schonberg <schonberg@adacore.com>
1747 * sem_ch12.adb (Analyze_Associations): minor reformatting.
1748 (Check_Fixed_Point_Actual): Do not emit a warning on a fixed
1749 point type actual that has user-defined arithmetic primitives,
1750 when there is a previous actual for a formal package that defines
1751 a fixed-point type with the parent user-defined operator.
1753 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
1755 * checks.adb (Generate_Range_Check): Reinstate part of previous change.
1756 * sem_attr.adb (Resolve_Attribute): Generate a range check when
1757 the component type allows range checks.
1759 2017-04-27 Ed Schonberg <schonberg@adacore.com>
1761 * sem_aux.adb (Is_Generic_Formal): Use original node to locate
1762 corresponding declaration, because formal derived types are
1763 rewritten as private extensions.
1765 2017-04-27 Ed Schonberg <schonberg@adacore.com>
1767 * sem_dim.adb (Analyze_Dimension_Binary_Op): Do not check
1768 dimensions of operands if node has been analyzed already, because
1769 previous analysis and dimension checking will have removed the
1770 dimension information from the operands.
1772 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
1774 * debug.adb: Document the use of switch -gnatd.s.
1775 * einfo.ads Update the documentation on attribute
1776 Sec_Stack_Needed_For_Return and attribute Uses_Sec_Stack. Remove
1777 the uses of these attributes from certain entities.

1779 which determines whether the block should continue to manage
1780 the secondary stack.

1857 * types.ads, osint.adb, sinput-c.adb, sinput-d.adb, sinput-l.adb,
1858 * sinput-p.adb: Use regular fat pointers, with bounds checking,
1859 for source buffers. Fix misc obscure bugs.
1860 * sinput.ads, sinput.adb: Use regular fat pointers, with bounds
1861 checking, for source buffers. Modify representation clause for
1862 Source_File_Record as appropriate. Move Source_File_Index_Table
1863 from spec to body, because it is not used outside the body.
1864 Move Set_Source_File_Index_Table into the private part, because
1865 it is used only in the body and in children. Use trickery to
1866 modify the dope in the generic instantiation case. It's ugly,
1867 but not as ugly as the previous method. Fix documentation.
1868 Remove obsolete code.

1884 expander is not active or when index/range checks are suppressed
1886 (Insert_List_After_And_Analyze, Insert_List_Before_And_Analyze):
1887 Remove variants that include a Supress parameter. These routines
1888 are never used, and were introduced before the current scope-based
1889 check suppression method.

1940 scn.ads, gnatls.adb: Eliminate the vestigial Internal_Source_File and
1941 the Internal_Source buffer. This removes the incorrect call to "="
1942 the customer noticed.
1943 Wrap remaining calls to "=" in Null_Source_Buffer_Ptr. We
1944 eventually need to eliminate them altogether. Or else get rid
1945 of zero-origin addressing.

2229 further expansion for the unchecked union.
2230 (Expand_Attribute_Reference, case 'Write): If the type is
2231 an unchecked_union, check whether enclosing scope is a Write
2232 subprogram. Replace attribute with a Raise_Program_Error if the

2322 operand as universal real when the operand is a multiplication
2323 or a division where both operands are of any fixed type.
2324 (Unique_Fixed_Point_Type): Add local variable ErrN. Improve the

2402 * sem_dim.adb (Dimensions_Of_Operand): minot cleanups: a) If
2403 dimensions are present from context, use them. b) If operand is

2453 (Build_Invariant_Procedure_Declaration): Remove condition
2454 to return if an interface type is encountered and add
2455 condition to convert the formal parameter to its class-wide
2456 counterpart if Work_Typ is abstract.

2478 * sem_ch3.adb (Derive_Subprogram): Implement rule in RM 6.1.1
2479 (10-15): if derived type T with progenitors is abstract,
2480 and primitive P of this type inherits non-trivial classwide
2481 preconditions from both a parent operation and from an interface
2482 operation, then the inherited operation is abstract if the parent
2483 operation is not null.
2484 * sem_disp.ads, sem_disp.adb: replace function Covers_Some_Interface
2485 with Covered_Interface_Op to yield the actual interface operation
2486 that is implemented by a given inherited operation.

2513 * sem_ch4.adb (Complete_Object_Interpretation): If an explicit
2514 dereference is introduced for the object, and the object is

2518 attribute types with the same designated type keep either of
2519 them and do not report an ambiguity. A true ambiguity will be

2524 * a-numeri.ads: Change the encoding of Greek letter Pi from
2525 brackets encoding to UTF-8. Use pragma Wide_Character_Encoding
2526 to indicate the encoding. We considered using a byte order mark
2527 (BOM), but that causes various trouble (misc software eats the
2528 BOM, if you have a patch with a BOM, then it's not at the start
2529 of the patch, so it's not a BOM, the BOM affects with-ing files,

2573 enforce legality rule on classwide preconditions inherited from
2574 both an ancestor and a progenitor (RM 6.1.1 (10-13).
2575 * sem_disp.adb (Check_Dispatching_Context): A call to an abstract
2576 subprogram need not be dispatching if it appears in a precondition
2577 for an abstract or null subprogram.
2579 2017-04-25 Gary Dismukes <dismukes@adacore.com>

2593 2017-04-25 Bob Duff <duff@adacore.com>
2595 * exp_aggr.adb (Component_Count): Protect the
2596 arithmetic from attempting to convert a value >= 2**31 to Int,
2597 which would otherwise raise Constraint_Error.
2599 2017-04-25 Bob Duff <duff@adacore.com>
2601 * opt.ads (Locking_Policy): Fix incorrect documentation. The

2625 Save and restore the value of global flag
2626 Ignore_SPARK_Mode_Pragmas_In_Instance. Set or reinstate the value

2628 the corresponding spec or the body must ignore all SPARK_Mode
2629 pragmas found within.
2630 (Analyze_Subprogram_Declaration): Mark
2631 the spec when it needs to ignore all SPARK_Mode pragmas found
2632 within to allow the body to infer this property in case it is
2633 instantiated or inlined later.
2634 * sem_ch7.adb (Analyze_Package_Body_Helper): Save and restore the
2635 value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Set
2636 the value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance
2637 when the corresponding spec also ignored all SPARK_Mode pragmas
2639 (Analyze_Package_Declaration): Mark the spec when

2670 Ignore_Pragma_SPARK_Mode.
2671 * sem_util.adb (SPARK_Mode_Is_Off): A construct which ignored
2672 all SPARK_Mode pragmas defined within yields mode "off".
2674 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
2676 * bindgen.adb, exp_dbug.adb, errout.adb, fname.adb: Minor reformatting.

2693 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
2695 * sem_util.adb (New_Copy_Tree): Put back the declarations of the
2696 hash tables at library level. Reinstate the NCT_Hash_Tables_Used
2697 variable and set it to True whenever the main hash table is
2698 populated. Short- circuit the Assoc function if it is false
2699 and add associated guards.
2701 2017-04-25 Olivier Hainque <hainque@adacore.com>
2703 * bindgen.adb (Gen_Elab_Calls): Also update counter of lone
2704 specs without elaboration code that have an elaboration counter
2705 nevertheless, e.g. when compiled with -fpreserve-control-flow.
2706 * sem_ch10.adb (Analyze_Compilation_Unit):
2707 Set_Elaboration_Entity_Required when requested to preserve
2708 control flow, to ensure the unit elaboration is materialized at
2709 bind time, resulting in the inclusion of the unit object file
2710 in the executable closure at link time.
2712 2017-04-25 Pierre-Marie de Rodat <derodat@adacore.com>
2714 * exp_dbug.adb: In Debug_Renaming_Declaration,
2715 when dealing with indexed component, accept to produce a renaming
2716 symbol when the index is an IN parameter or when it is a name
2717 defined in an outer scope.
2719 2017-04-25 Yannick Moy <moy@adacore.com>
2721 * errout.adb (Error_Msg): Adapt continuation
2722 message in instantiations and inlined bodies for info messages.
2724 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
2726 * fname.adb (Has_Internal_Extension): Add pragma Inline.
2727 Use direct 4-character slice comparisons.
2729 pragma Inline. (Has_Suffix): Delete.
2730 (Is_Internal_File_Name):
2731 Test Is_Predefined_File_Name first.
2732 (Is_Predefined_File_Name):

2736 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
2738 * checks.adb (Insert_Valid_Check): Code cleanup.
2739 * exp_ch6.adb (Add_Validation_Call_By_Copy_Code): New routine.
2740 (Expand_Actuals): Generate proper copy-back for a validation
2741 variable when it acts as the argument of a type conversion.
2742 * sem_util.adb (Is_Validation_Variable_Reference): Augment the
2743 predicate to operate on type qualifications.
2745 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
2747 * sem_prag.adb, exp_ch6.adb, binde.adb, sem_disp.adb, s-fileio.adb:
2750 2017-04-25 Bob Duff <duff@adacore.com>
2752 * sem_prag.adb (No_Return): Give an error if the pragma applies
2753 to a body. Specialize the error for the specless body case,
2754 as is done for (e.g.) pragma Convention.
2755 * debug.adb: Add switch -gnatd.J to disable the above legality
2756 checks. This is mainly for use in our test suite, to avoid
2757 rewriting a lot of illegal (but working) code. It might also
2758 be useful to customers. Under this switch, if a pragma No_Return
2759 applies to a body, and the procedure raises an exception (as it
2760 should), the pragma has no effect. If the procedure does return,
2761 execution is erroneous.
2763 2017-04-25 Bob Duff <duff@adacore.com>
2765 * exp_ch6.adb (Expand_Actuals): This is the
2766 root of the problem. It took N as an 'in out' parameter, and in
2767 some cases, rewrote N, but then set N to Original_Node(N). So
2768 the node returned in N had no Parent. The caller continued
2769 processing of this orphaned node. In some cases that caused a
2770 crash (e.g. Remove_Side_Effects climbs up Parents in a loop,
2771 and trips over the Empty Parent). The solution is to make N an
2772 'in' parameter. Instead of rewriting it, return the list of
2773 post-call actions, so the caller can do the rewriting later,
2774 after N has been fully processed.
2775 (Expand_Call_Helper): Move most of Expand_Call here. It has
2776 too many premature 'return' statements, and we want to do the
2777 rewriting on return.
2778 (Insert_Post_Call_Actions): New procedure to insert the post-call
2779 actions in the appropriate place. In the problematic case,
2780 that involves rewriting N as an Expression_With_Actions.
2781 (Expand_Call): Call the new procedures Expand_Call_Helper and
2782 Insert_Post_Call_Actions.
2784 2017-04-25 Ed Schonberg <schonberg@adacore.com>
2786 * sem_prag.adb (Inherits_Class_Wide_Pre): Cleanup code, handle
2787 properly type derived from generic formal types, to handle
2788 properly modified version of ACATS 4.1B B611017.
2790 2017-04-25 Javier Miranda <miranda@adacore.com>
2792 * exp_unst.adb (Subp_Index): Adding missing
2793 support for renamings and functions that return a constrained
2794 array type (i.e. functions for which the frontend built a
2795 procedure with an extra out parameter).
2797 2017-04-25 Pascal Obry <obry@adacore.com>
2799 * s-string.adb: Minor code clean-up.
2801 2017-04-25 Bob Duff <duff@adacore.com>

2806 function for Non_Blocking_Wait_Process.
2808 2017-04-25 Bob Duff <duff@adacore.com>
2810 * prep.adb (Preprocess): Remove incorrect
2811 Assert. Current character can be ASCII.CR.
2813 2017-04-25 Ed Schonberg <schonberg@adacore.com>
2815 * sem_prag.adb (Set_Convention_From_Pragma): Cleanup code for
2816 convention Stdcall, which has a number of exceptions. Convention
2817 is legal on a component declaration whose type is an anonymous
2818 access to subprogram.
2820 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
2822 * sem_ch4.adb: sem_ch4.adb Various reformattings.
2823 (Try_One_Prefix_Interpretation): Use the base type when dealing
2824 with a subtype created for purposes of constraining a private
2825 type with discriminants.
2827 2017-04-25 Javier Miranda <miranda@adacore.com>
2829 * einfo.ads, einfo.adb (Has_Private_Extension): new attribute.

2831 dispatching primitives (Restore_Warnings): Restore warning on
2832 late dispatching primitives (Save_Warnings): Save warning on late
2833 dispatching primitives (Do_Warning_Switch): Use -gnatw.j/-gnatw.J
2834 to enable/disable this warning.
2835 (WA_Warnings): Set warning on late dispatching primitives.
2836 * sem_ch3.adb (Analyze_Private_Extension_Declaration): Remember
2837 that its parent type has a private extension.
2838 * sem_disp.adb (Warn_On_Late_Primitive_After_Private_Extension):
2840 * usage.adb: Document -gnatw.j and -gnatw.J.
2842 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>

2847 2017-04-25 Bob Duff <duff@adacore.com>
2849 * binde.adb (Validate): Do not pass dynamic strings
2850 to pragma Assert, because older compilers do not support that.
2852 2017-04-25 Bob Duff <duff@adacore.com>
2854 * s-fileio.adb (Close): When a temp file is
2855 closed, delete it and clean up its Temp_File_Record immediately,
2856 rather than waiting until later.
2857 (Temp_File_Record): Add File
2858 component, so Close can know which Temp_File_Record corresponds
2859 to the file being closed.
2860 (Delete): Don't delete temp files,
2861 because they are deleted by Close.
2862 (Open): Set the File component
2863 of Temp_File_Record. This requires moving the creation of the
2864 Temp_File_Record to the end, after the AFCB has been created.
2866 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
2868 * checks.adb (Insert_Valid_Check): Do not generate
2869 a validity check when inside a generic.

2883 concerning inheritance of class-wide preconditions do not apply
2886 2017-04-25 Bob Duff <duff@adacore.com>
2888 * s-ficobl.ads: Minor comment fix.
2890 2017-04-25 Yannick Moy <moy@adacore.com>
2892 * checks.adb (Apply_Scalar_Range_Check): Analyze precisely
2893 conversions from float to integer in GNATprove mode.
2894 (Apply_Type_Conversion_Checks): Make sure in GNATprove mode
2895 to call Apply_Type_Conversion_Checks, so that range checks
2896 are properly positioned when needed on conversions, including
2897 when converting from float to integer. (Determine_Range): In
2898 GNATprove mode, take into account the possibility of conversion
2899 from float to integer.
2900 * sem_res.adb (Resolve_Type_Conversion): Only enforce range
2901 check on conversions from fixed-point to integer, not anymore
2902 on conversions from floating-point to integer, when in GNATprove
2905 2017-04-25 Yannick Moy <moy@adacore.com>
2907 * checks.adb (Determine_Range_R): Special case type conversions
2908 from integer to float in order to get bounds in that case too.
2909 * eval_fat.adb (Machine): Avoid issuing warnings in GNATprove
2910 mode, for computations involved in interval checking.

2924 * exp_attr.adb (Make_Range_Test): Add processing for validation
2925 variables to avoid extra reads and copies of the prefix.
2926 * exp_ch6.adb (Expand_Actuals): Add copy-back for validation
2927 variables in order to reflect any changes done in the variable
2928 back into the original object.
2929 * sem_util.adb (Is_Validation_Variable_Reference): New routine.
2930 * sem_util.ads (Is_Validation_Variable_Reference): New routine.

2938 2017-04-25 Ed Schonberg <schonberg@adacore.com>
2940 * sem_prag.adb (Inherits_Class_Wide_Pre): subsidiary of
2941 Analyze_Pre_Post_Condition, to implement the legality checks
2942 mandated by AI12-0131: Pre'Class shall not be specified for an
2943 overriding primitive subprogram of a tagged type T unless the
2944 Pre'Class aspect is specified for the corresponding primitive
2945 subprogram of some ancestor of T.
2947 2017-04-25 Bob Duff <duff@adacore.com>
2949 * sem_ch8.adb (Use_One_Type): If a use_type_clause
2950 is redundant, set its Used_Operations to empty. This is only
2951 necessary for use clauses that appear in the parent of a generic
2952 child unit, because those use clauses get reanalyzed when we
2953 instantiate the generic, and we don't want the Used_Operations
2954 carried over from the original context (where it was probably
2957 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>

2973 'Class, if prefix type is synchronized and previous errors
2974 have suppressed the creation of the corresponding record type,
2975 create a spurious class-wide for the synchonized type itself,
2976 to catch other misuses of the attribute

2984 if CodePeer_Mode is True, then don't generate the
2985 tag checks for the result of call to an instance of
2986 Ada.Tags.Generic_Dispatching_Constructor (i.e., both the "is a
2987 descendant of" check and the accessibility check).
2989 2017-04-25 Ed Schonberg <schonberg@adacore.com>

2998 (Expand_Concatenate): When optimization is enabled, also expand
2999 the operation out-of-line if the concatenation is present within
3000 the expression of the declaration of a library-level object and
3001 not only if it is the expression of the declaration.
3003 2017-04-25 Bob Duff <duff@adacore.com>
3005 * freeze.adb (Freeze_Object_Declaration): Do
3006 not Remove_Side_Effects if there is a pragma Linker_Section,
3007 because in that case we want static initialization in the
3008 appropriate section.
3010 2017-04-25 Gary Dismukes <dismukes@adacore.com>
3012 * exp_dbug.adb: Minor rewording and reformatting.

3017 handle the proposed changes to rules concerning potentially
3018 unevaluated expressions, to include selected components that
3019 do not depend on discriminants, and indexed components with
3021 * sem_util.adb (Is_Potentially_Unevaluated): Add check for
3022 predicate in quantified expression, and fix bugs in the handling
3023 of case expressions and membership test.
3024 (Analyze_Attribute_Old_Result): use new predicate.
3025 (Analyze_Attribute, case Loop_Entry): ditto.
3027 2017-04-25 Bob Duff <duff@adacore.com>

3030 explaining why we don't need to walk all the chunks in order to
3031 compute the total size.
3033 2017-04-25 Bob Duff <duff@adacore.com>
3035 * namet.ads, namet.adb (Global_Name_Buffer): Increase the length
3036 of the global name buffer to 4*Max_Line_Length.
3038 2017-04-25 Javier Miranda <miranda@adacore.com>
3040 * exp_ch8.adb (Expand_N_Object_Renaming_Declaration): When creating a
3041 renaming entity for debug information, mark the entity as needing debug
3042 info if it comes from sources.
3044 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
3046 * sem_ch13.adb (Analyze_Attribute_Definition_Clause): Remove the
3047 restriction converning the use of 'Address where the prefix is
3048 of a controlled type.
3050 2017-04-25 Pierre-Marie de Rodat <derodat@adacore.com>

3067 operations, in default values for same, and in contract guards
3068 for contract cases in SPARK.
3070 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
3072 * a-numaux.ads: Fix description of a-numaux-darwin
3074 (Double): Define to Long_Float.
3075 * a-numaux-vxworks.ads (Double): Likewise.
3076 * a-numaux-darwin.ads

3079 * a-numaux-x86.ads: Fix package description.
3080 * a-numaux-x86.adb (Is_Nan): Minor tweak.
3081 (Reduce): Adjust and complete description. Call Is_Nan instead of
3082 testing manually. Use an integer temporary to hold rounded value.
3083 * a-numaux-darwin.adb (Reduce): Likewise.
3084 (Is_Nan): New function.
3086 2017-04-25 Ed Schonberg <schonberg@adacore.com>
3088 * sem_ch4.adb (Analyze_Selected_Component): Additional refinement
3089 on analysis of prefix whose type is a current instance of a
3090 synchronized type, but where the prefix itself is an entity that
3093 2017-04-25 Ed Schonberg <schonberg@adacore.com>
3095 * exp_ch5.adb (Replace_Target): When rewriting the RHS, preserve
3096 the identity of callable entities therein, because they have been
3097 properly resolved, and prefixed calls may have been rewritten
3100 2017-04-25 Patrick Bernardi <bernardi@adacore.com>
3102 * exp_ch3.adb (Build_Init_Statements): Convert
3103 the expression of the pragma/aspect Secondary_Stack_Size to
3104 internal type System.Parameters.Size_Type before assigning
3105 it to the Secondary_Stack_Size component of the task type's
3106 corresponding record.
3108 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
3110 * sem_eval.adb (Compile_Time_Compare): Reinstate the expr+literal
3111 (etc) optimizations when the type is modular and the offsets
3114 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
3116 * s-osinte-freebsd.ads: Minor comment tweaks
3118 2017-04-25 Javier Miranda <miranda@adacore.com>
3120 * urealp.adb (UR_Write): Reverse previous patch
3121 adding documentation on why we generate multiplications instead
3122 of divisions (needed to avoid expressions whose computation with
3123 large numbers may cause division by 0).
3125 2017-04-25 Bob Duff <duff@adacore.com>
3127 * erroutc.adb (Set_Specific_Warning_Off,
3128 Set_Warnings_Mode_Off): Use the correct source file for
3129 Stop. Was using Current_Source_File, which is only valid during
3130 parsing. Current_Source_File will have a leftover value from
3131 whatever file happened to be parsed last, because of a with_clause
3134 2017-04-25 Bob Duff <duff@adacore.com>
3136 * lib.ads, lib.adb (In_Internal_Unit): New functions similar
3137 to In_Predefined_Unit, but including GNAT units.
3138 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): Replace
3139 with Should_Ignore_Pragma_Par and Should_Ignore_Pragma_Sem,
3140 because Should_Ignore_Pragma was not working reliably outside
3141 the parser, because Current_Source_File is not valid.
3142 * sem_prag.adb, exp_prag.adb: Call Should_Ignore_Pragma_Sem.
3143 * par-prag.adb: Call Should_Ignore_Pragma_Par.
3145 2017-04-25 Arnaud Charlet <charlet@adacore.com trojanek>
3147 * gnat1drv.adb (Gnat1Drv): Disable Generate_Processed_File in

3158 * sem_prag.adb (Analyze_Pragma, Process_Import_Or_Interface):
3159 Add extra parameter for Process_Interface_Name.

3173 attempt evaluation of relational operations inside assertions.
3175 2017-04-25 Justin Squirek <squirek@adacore.com>

3178 Restored, code moved back from Build_Invariant_Procedure_Body.
3179 (Add_Parent_Invariants): Restored, code moved back from
3180 Build_Invariant_Procedure_Body.
3181 (Build_Invariant_Procedure_Body):
3182 Remove refactored calls and integrated code from
3183 Add_Parent_Invariants and Add_Interface_Invariants.
3185 2017-04-25 Johannes Kanig <kanig@adacore.com>
3187 * errout.adb (Output_Messages): Adjust computation of total
3189 * erroutc.adb (Error_Msg): In statistics counts, deal
3190 correctly with informational messages that are not warnings.

3202 2017-04-25 Justin Squirek <squirek@adacore.com>
3204 * sem_ch3.adb (Analyze_Declarations): Minor
3205 correction to comments, move out large conditional and scope
3206 traversal into a predicate.
3207 (Uses_Unseen_Lib_Unit_Priv): Predicate function made from extracted
3210 2017-04-25 Ed Schonberg <schonberg@adacore.com>
3212 * sem_ch4.adb (Analyze_Selected_Component): Refine analysis
3213 of prefix whose type is a current instance of a synchronized
3214 type. If the prefix is an object this is an external call (or
3215 requeue) that can only access public operations of the object. The
3216 previous predicate was too restrictive, and did not allow public
3217 protected operations, only task entries.
3219 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
3221 * sem_ch5.adb, fname.adb: Minor reformatting.
3223 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
3225 * einfo.adb (Is_Anonymous_Access_Type): New routine.
3226 * einfo.ads Update the placement of
3227 E_Anonymous_Access_Subprogram_Type along with all subtypes that
3229 (Is_Anonymous_Access_Type): New routine.
3230 * exp_ch7.adb (Allows_Finalization_Master): Do not generate a
3231 master for an access type subject to pragma No_Heap_Finalization.
3232 * exp_util.adb (Build_Allocate_Deallocate_Proc): An object being
3233 allocated or deallocated does not finalization actions if the
3234 associated access type is subject to pragma No_Heap_Finalization.
3235 * opt.ads Add new global variable No_Heap_Finalization_Pragma.
3236 * par-prag.adb Pragma No_Heap_Finalization does not need special
3237 processing from the parser.
3238 * sem_ch6.adb (Check_Return_Subtype_Indication): Remove ancient
3239 ??? comments. Use the new predicate Is_Anonymous_Access_Type.
3240 * sem_prag.adb Add an entry in table Sig_Flags for pragma
3241 No_Heap_Finalization.
3242 (Analyze_Pragma): Add processing for
3243 pragma No_Heap_Finalization. Update various error messages to
3244 use Duplication_Error.
3245 * sem_util.ads, sem_util.adb (No_Heap_Finalization): New routine.
3246 * snames.ads-tmpl: Add new predefined name No_Heap_Finalization
3247 and corresponding pragma id.
3249 2017-04-25 Bob Duff <duff@adacore.com>
3251 * freeze.adb (Freeze_Record_Type): Use the
3252 underlying type of the component type to determine whether it's
3253 elementary. For representation clause purposes, a private type
3254 should behave the same as its full type.
3255 * fname.ads, fname.adb (Is_Predefined_File_Name):
3256 Make sure things like "system.ali" are recognized as predefined.
3258 2017-04-25 Javier Miranda <miranda@adacore.com>
3260 * debug.adb: Update documentation of -gnatd.6.

3264 * sem_ch5.adb (Preanalyze_Range): Handle properly an Ada2012
3265 element iterator when the name is an overloaded function call,
3266 one of whose interpretations yields an array.
3268 2017-04-25 Bob Duff <duff@adacore.com>
3270 * uname.ads, uname.adb (Is_Predefined_Unit_Name,
3271 Is_Internal_Unit_Name): New functions for operating on unit
3272 names, as opposed to file names. There's some duplicated code
3273 with fname.adb, which is unfortunate, but it seems like we don't
3274 want to add dependencies here.
3275 * fname-uf.adb (Get_File_Name): Change Is_Predefined_File_Name
3276 to Is_Predefined_Unit_Name; the former was wrong, because Uname
3277 is not a file name at all.
3278 * fname.ads, fname.adb: Document the fact that
3279 Is_Predefined_File_Name and Is_Internal_File_Name can be called
3280 for ALI files, and fix the code so it works properly for ALI
3281 files. E.g. these should return True for "system.ali".
3283 2017-04-25 Justin Squirek <squirek@adacore.com>
3285 * exp_util.adb (Add_Invariant): Removed,
3286 code moved to Add_Invariant_Check, Add_Inherited_Invariant,
3287 and Add_Own_Invariant. (Add_Invariant_Check): Used
3288 for adding runtime checks from any kind of invariant.
3289 (Add_Inherited_Invariant): Generates invariant checks for
3290 class-wide invariants (Add_Interface_Invariants): Removed, code
3291 moved to Build_Invariant_Procedure_Body (Add_Own_Invariant):

3293 Removed, code moved to Build_Invariant_Procedure_Body
3294 (Build_Invariant_Procedure_Body): Add refactored calls
3295 and integrated code from Add_Parent_Invariants and
3296 Add_Interface_Invariants.
3297 (Process_Type): Removed, the
3298 relavant code was inlined into both Add_Own_Invariant and
3299 Add_Inherited_Invariant.
3301 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
3303 * make.adb, par-ch2.adb, sem_util.adb, scans.ads, sem_ch8.adb,

3320 and Build_Invariant_Procedure_Declaration.
3321 * exp_util.ads, exp_util.adb Add Build_Invariant_Procedure_Body
3322 and Build_Invariant_Procedure_Declaration from exp_ch7
3323 and break-out Is_Untagged_Private_Derivation from
3324 Build_Invariant_Procedure_Body.
3325 (Replace_Type_References):
3326 Append an extra parameter to allow for dispatching replacements
3327 and add the corrasponding logic.
3328 (Type_Invariant): Remove
3329 Replace_Typ_Refs and replace its references with calls to
3330 Replace_Type_References.
3331 * sem_ch3.adb, sem_prag.adb: Remove with and use of exp_ch7.
3333 2017-04-25 Bob Duff <duff@adacore.com>
3335 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): New function
3336 that returns True when appropriate.
3337 * par-prag.adb, exp_prag.adb, sem_prag.adb: Do not ignore pragmas
3338 when compiling predefined files.
3339 * fname.ads, fname.adb (Is_Predefined_File_Name): Fix bug:
3340 "gnat.adc" should not be considered a predefined file name.
3341 That required (or at least encouraged) a lot of cleanup of global
3342 variable usage. We shouldn't be communicating information via
3343 the global name buffer.
3344 * bindgen.adb, errout.adb, fname-uf.adb, lib-load.adb, make.adb,
3345 * restrict.adb, sem_ch10.adb, sem_ch6.adb, sem_ch8.adb: Changes

3365 * stringt.ads, stringt.adb, exp_dbug.adb, sem_dim.adb: Remove
3366 Add_String_To_Name_Buffer, to avoid using the global Name_Buf.
3367 Add String_To_Name with no side effects.
3369 2017-04-25 Justin Squirek <squirek@adacore.com>
3371 * sem_ch3.adb (Analyze_Declarations): Add
3372 additional condition for edge case.

3376 * par-ch2.adb, scans.ads, scn.adb: Do not give an error for
3377 reserved words inside pragmas. This is necessary to allow the
3378 pragma name Interface to be used in pragma Ignore_Pragma.

3404 * sem_ch5.adb (Analyze_Assignment): Reset Full_Analysis flag on
3405 the first pass over an assignment statement with target names,
3406 to prevent the generation of subtypes (such as discriminated
3407 record components)that may carry the target name outside of the

3409 the assignment is reanalyzed in full.
3410 (Analyze_Target_Name): Handle properly class-wide types.

3421 refer to the proper entities. Update the replacement of
3423 (Build_DIC_Procedure_Body): Add formal parameter
3424 For_Freeze. Add local variable Build_Body. Inherited DIC pragmas
3425 are now only processed when freezing occurs. Build a body only

3442 properties of the private type to the full view in case the full
3443 view derives from a parent type and inherits a DIC pragma.
3444 * sem_prag.adb (Analyze_Pragma): Guard against a case where a
3445 DIC pragma is placed at the top of a declarative region.
3447 2017-04-25 Arnaud Charlet <charlet@adacore.com trojanek>

3450 int to avoid overflow checks.
3452 2017-04-25 Ed Schonberg <schonberg@adacore.com>
3454 * sem_attr.adb (Analyze_Attribute, case 'Access): Specialize
3455 the error message when the attribute reference is an actual in
3456 a call to a subprogram inherited from a generic formal type with
3457 unknown discriminants, which makes the subprogram and its formal
3458 parameters intrinsic (see RM 6.3.1 (8) and (13)).
3460 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
3462 * sem_aggr.adb, inline.adb, einfo.adb, einfo.ads, scng.adb,

3465 2017-04-25 Bob Duff <duff@adacore.com>
3467 * sem_attr.adb (Type_Key): Add code in the
3468 recursive Compute_Type_Key to protect against fetching the source
3469 code for Standard, in case a component of the type is declared
3470 in Standard. There was already code to do this for the original
3471 type, but not for its components.
3473 2017-04-25 Javier Miranda <miranda@adacore.com>
3475 * exp_ch3.adb (Build_Initialization_Call): Handle
3476 subtypes of private types when searching for the underlying full

3491 or inlining purposes, the body of U1 needs to be compiled as well.
3492 * sem_prag.adb (Process_Inline): Set Body_Needed_For_Inlining if
3493 context is a package declaration.
3494 * sem_ch12.adb (Analyze_Generic_Subprogram_Declaration,
3495 Analyze_Generic_Package_Declaration): ditto.

3514 2017-04-25 Bob Duff <duff@adacore.com>
3516 * s-memory.adb: Add a comment regarding efficiency.
3517 * atree.adb: Fix the assertion, and combine 2 assertions into one,
3518 "the source has an extension if and only if the destination does."

3528 * init.c (__gnat_error_handler) [vxworks]: Turn on sigtramp
3529 handling for ppc64-vx7.

3540 Direct_Val (Right), instead of the incorrect Direct_Val (Left).
3541 (UI_GCD): Remove ??? comment involving possible efficiency
3542 improvements. This just isn't important after all these years.

4169 (Check_Dependency_Clause): Properly detect a match between two
4170 'Result attributes. Update the various post-match cases to use

4174 (Remove_Extra_Clauses): New routine.
4175 (Report_Extra_Clauses): Remove the detection of ... => null

4234 subsidiary to Expand_N_Object_ Declaration, to compute a guard on
4235 an object declaration for an array type with a modular index type
4236 with the size of Long_Long_Integer. Special processing is needed
4237 in this case to compute reliably the size of the object, and
4238 eventually to raise Storage_Error, when wrap-around arithmetic
4239 might compute a meangingless size for the object.

4248 * sem_res.adb (Resolve_Call): In the part of the code where
4249 it is deciding whether to turn the call into an indexed
4250 component, avoid doing so if the call is to an instance of
4251 Unchecked_Conversion. Otherwise, the compiler turns it into an
4252 indexed component, and resolution of that turns it back into a
4253 function call, and so on, resulting in infinite recursion.
4254 * sem_util.adb (Needs_One_Actual): If the first formal has a

4302 * sem_ch13.adb (Analyze_Aspect_Specifications): Aspect Alignment
4303 must be treated as delayed aspect even if the expression is

4357 returns a limited view of a type and at the point of the call the
4358 function is not declared in the extended main unit then replace
4359 it with the non-limited view, which must be available. If the
4360 called function is in the extended main unit then no action is
4361 needed since the back-end handles this case.

4375 * sem_ch3.adb (Complete_Private_Subtype): If the scope of the
4376 base type differs from that of the completion and the private
4377 subtype is an itype (created for a constraint on an access

4579 components invariants of composite types are not checked by
4580 the composite type's invariant procedure in GNATprove mode.
4581 (Build_Invariant_Procedure_Declaration): Semi-insert the
4582 declaration into the tree for GNATprove by setting its Parent
4584 * freeze.adb (Freeze_Arry_Type):In GNATprove mode, do not add
4585 the component invariants to the array type invariant procedure
4586 so that the procedure can be used to check the array type
4588 (Freeze_Record_Type): In GNATprove mode, do
4589 not add the component invariants to the record type invariant
4590 procedure so that the procedure can be used to check the record
4591 type invariants if any.
4593 2017-01-19 Hristian Kirtchev <kirtchev@adacore.com>
4595 * lib-xref-spark_specific.adb: Minor reformatting.

4608 incomplete return type after attempting to freeze it, so that
4609 other freeze actiona are generated in the proper order.
4611 2017-01-19 Ed Schonberg <schonberg@adacore.com>
4613 * sem_aggr.adb (Resolve_Aggregate): If the type is a string
4614 type, ie. a type whose component is a character type, and the
4615 aggregate is positional, do not convert into a string literal
4616 if the index type is not an integer type, because the original
4617 type may be required in an enclosing operation.
4619 2017-01-19 Bob Duff <duff@adacore.com>
4621 * binde.adb, debug.adb: Enable new elaboration order algorithm
4622 by default. -dp switch reverts to the old algorithm.

4630 * sem_ch7.adb Remove the with and use clauses for Exp_Ch7
4632 (Analyze_Package_Specification): Remove the
4633 generation of the DIC and Invariant procedure bodies. This is
4634 now done by Analyze_Declarations.
4635 * sem_disp.adb (Check_Dispatching_Operation): DIC and Invariant
4636 procedures are never treated as primitives.
4638 2017-01-19 Yannick Moy <moy@adacore.com>

4667 * exp_ch6.adb (Expand_Call): Remove side effects on
4668 actuals that are allocators with qualified expression since the
4669 initialization of the object is performed by means of individual
4670 statements (and hence it must be done before the call).
4672 2017-01-19 Ed Schonberg <schonberg@adacore.com>
4674 * sem_ch3.adb (Analyze_Declarations): Minor reformatting.
4675 (Build_Derived_Enumeration_Type): If the derived type inherits a
4676 dynamic predicate from its parent, the bounds of the type must
4677 freeze because an explicit constraint is constructed for the
4678 type and the corresponding range is elaborated now.
4680 2017-01-19 Arnaud Charlet <charlet@adacore.com>
4682 * sem_attr.ads: minor fix of inconsistent casing in comment

4708 public, for use elsewhere.
4709 * sem_ch6.adb (Analyze_Procedure_Call): In SPARK_Mode and within
4710 an Inlined_body, recognize a call that uses object notation
4711 and has not been rewritten as a regular call because regular
4712 expansion has not taken place.
4714 2017-01-19 Bob Duff <duff@adacore.com>
4716 * checks.adb (Apply_Type_Conversion_Checks): Disable small optimization
4717 in case of generic formal discrete types, because it causes crashes in

4725 2017-01-19 Bob Duff <duff@adacore.com>
4727 * bcheck.adb (Check_Consistent_Dynamic_Elaboration_Checking):
4728 Increment Warnings_Detected. It was decrementing, which is
4729 wrong since we just issued a warning message.
4730 * binderr.ads (Errors_Detected, Warnings_Detected): Declare
4731 these variables to be of subtype Nat instead of Int, because
4732 they should never be negative.
4734 2017-01-19 Javier Miranda <miranda@adacore.com>
4736 * contracts.adb (Build_Postconditions_Procedure): Replace
4737 Generate_C_Code by Modify_Tree_For_C.

4750 * sem_res.adb (Resolve_Type_Conversion): Replace Generate_C_Code
4751 by Modify_Tree_For_C.
4752 * sinfo.ads (Modify_Tree_For_C): Adding documentation.
4754 2017-01-19 Javier Miranda <miranda@adacore.com>
4756 * sem_util.ads, sem_util.adb (Expression_Of_Expression_Function): New
4758 (Is_Inlinable_Expression_Function): New subprogram.
4759 * exp_ch6.ads, exp_ch6.adb (Expression_Of_Expression_Function): Moved
4761 (Is_Inlinable_Expression_Function): Moved to Sem_Util.
4763 2017-01-19 Ed Schonberg <schonberg@adacore.com>
4765 * sem_ch4.adb (Diagnose_Call): Improve error message when a
4766 selected component has a prefix that might be interpreted
4767 as a parameterless function call, but none of the candidate
4768 interpretations is parameterless, and there is a hidden homonym
4769 of the prefix that is a package.
4770 * sem_ch8.adb (Find_Selected_Component): If the prefix might be
4771 interpreted as a parameterless function call and its analysis
4772 fails, do not call Analyze_Selected_Component.
4774 2017-01-19 Steve Baird <baird@adacore.com>
4776 * sem_util.ads: Add new Use_Full_View Boolean parameter to
4778 * sem_util.adb (Get_Index_Bounds): replace calls to Scalar_Range with
4779 calls to a newly-defined Scalar_Range_Of_Right_View function.
4781 2017-01-19 Arnaud Charlet <charlet@adacore.com>

4784 * lib-xref.ads (Traverse_Compilation_Unit): declaration moved
4785 to visible part of the package to allow re-use in GNATprove.
4786 * lib-xref-spark_specific.adb (Traverse_Stub): routine refactored
4787 from repeated code of Traverse_Compilation_Unit.
4788 (Traverse_Declaration_Or_Statement): fixed detection of
4789 generic subprograms and packages; also, iteration over case
4790 statement alternatives rewritten to avoid testing if the first
4791 alternative is present (since it must be present due to Ada
4792 syntax restrictions).
4794 2017-01-19 Hristian Kirtchev <kirtchev@adacore.com>
4796 * exp_ch6.adb (Expand_N_Subprogram_Body): Mark the spec as
4797 returning by reference not just for subprogram body stubs,
4798 but for all subprogram cases.
4799 * sem_util.adb: Code reformatting.
4800 (Requires_Transient_Scope): Update the call to Results_Differ.

4804 2017-01-19 Ed Schonberg <schonberg@adacore.com>
4806 * sem_dim.adb (Analyze_Dimension): Analyze object declaration and
4807 identifier nodes that do not come from source, to handle properly
4808 dimensionality check within an inlined body which inclddes both
4809 original operands and rewritten operands. This removes spurious
4810 dimensionality errors in the presence of front-end inlining,
4811 as well as in SPARK mode.
4813 2017-01-16 Jakub Jelinek <jakub@redhat.com>

4852 * scil_ll.adb: Minor style fix in comment.
4853 * sem_ch8.adb (Analyze_Expanded_Name): Perform dimension analysis
4854 even if entity is already set, because the node may be renalyzed
4855 after inlining transformations.

4859 * sem_res.adb (Resolve_Call): Do not establish a transient scope
4860 for a call to inlinable expression function (since the call will
4861 be replaced by its returned object).

4884 * sem_ch6.adb (Cloned_Expression): New subprogram.
4885 (Freeze_Expr_Types): Complete previous patch since the expression
4886 of an expression-function may have iterators and loops with
4887 defining identifiers which, as part of the preanalysis of the
4888 expression, may be left decorated with itypes that will not be
4889 available in the tree passed to the backend.
4891 2017-01-13 Ed Schonberg <schonberg@adacore.com>

4906 2017-01-13 Hristian Kirtchev <kirtchev@adacore.com>
4908 * sem_ch6.adb (Analyze_Subprogram_Body_Helper):
4909 Ensure that the input body is a subprogram body before trying to
4910 determine whether it denoted an expression function. Note that
4911 subprogram body stubs cannot denote expression functions.
4913 2017-01-13 Gary Dismukes <dismukes@adacore.com>
4915 * bindgen.adb, sem_ch6.adb, binde.adb, exp_ch3.adb: Minor reformatting

4920 * einfo.ads (Component_Bit_Offset): Fix documentation.
4921 * sem_ch13.adb (Check_Record_Representation_Clause): Skip check

4929 2017-01-13 Bob Duff <duff@adacore.com>
4931 * binde.adb (Elab_New): New elaboration order algorithm
4932 that is expected to cause fewer ABE issues. This is a work in
4933 progress. The new algorithm is currently disabled, and can be
4934 enable by the -dp switch, or by modifying the Do_Old and Do_New
4935 etc. flags and rebuilding. Experimental code is included to
4936 compare the results of the old and new algorithms.
4937 * binde.ads: Use GNAT.Dynamic_Tables instead of Table, so we
4938 can have multiple of these tables, so the old and new algorithms
4940 * bindgen.ads (Gen_Output_File): Pass Elab_Order as an 'in'
4941 parameter of type array. This avoids the global variable, and
4942 allows bounds checking (which is normally defeated by the tables
4943 packages). It also ensures that the Elab_Order is read-only
4945 * bindgen.adb: Pass Elab_Order as an 'in' parameter to all
4946 subprograms that need it, as above.
4947 * debug.adb: Document new -dp switch. Modify doc of old -do
4949 * gnatbind.adb (Gnatbind): Make use of new interfaces to Binde
4950 and Bindgen. Move writing of closure (-R and -Ra switches)
4951 to Binde; that's more convenient.
4953 2017-01-13 Ed Schonberg <schonberg@adacore.com>
4955 * sem_ch6.adb (Analyze_Expression_Function): If the expression
4956 function is a completion, all entities referenced in the
4957 expression are frozen. As a consequence, a reference to an
4958 uncompleted private type from an enclosing scope is illegal.
4960 2017-01-13 Javier Miranda <miranda@adacore.com>
4962 * sem_ch6.adb (Freeze_Expr_Types): New subprogram.
4963 (Analyze_Subprogram_Body_Helper): At the occurrence of an
4964 expression function declaration that is a completion, its
4965 expression causes freezing (AI12-0103).
4967 2017-01-13 Vadim Godunko <godunko@adacore.com>
4969 * a-coinho-shared.adb: Fix memory leaks in Constant_Reference and

5023 Iterated_Component_Associations.
5024 (Gen_Loop): Generate proper loop for an
5025 Iterated_Component_Association: loop variable has the identifier
5026 of the original association. Generate a loop even for a single
5027 component choice, in order to make loop parameter visible in
5029 (Flatten): An Iterated_Component_Association is not static.

5053 mode a choice that is a subtype with a static predicate is
5054 replaced by the values it covers. This transformation must not
5055 be performed in ASIS mode, to preserve the source for analysis.
5057 2017-01-13 Justin Squirek <squirek@adacore.com>

5079 has a Discrete_Choices list, as specified in the RM. A
5080 Component_Association for aggregate uses instead a Choices list.

5117 when not applicable due to actual requiring type conversion
5118 with possible check but no temporary value can be copied for
5119 GNATprove to see the check.
