38 Eric Botcazou <ebotcazou@adacore.com>
40 * sem_ch4.adb (Analyze_Call): In Ada2012 an incomplete type from a
41 limited view may appear in the profile of a function, and a call to
42 that function in another unit in which the full view is available must
43 use this full view to spurious type errors at the point of call.

180 * exp_ch6.adb (Expand_Call_Helper): When locating the
181 accessibility entity created for an access parameter, handle
182 properly a reference to a formal of an enclosing subprogram. if
183 the reference appears in an inherited class-wide condition, it
184 is the rewriting of the reference in the ancestor expression,
185 but the accessibility entity must be that of the current formal.
187 2017-05-02 Javier Miranda <miranda@adacore.com>
189 * exp_ch4.adb (Expand_Non_Binary_Modular_Op): New subprogram.

220 pastos in part #3 of the head comment.
222 2017-05-02 Ed Schonberg <schonberg@adacore.com>
224 * exp_ch3.adb (Freeze_Type): Do not generate an invariant
225 procedure body for a local (sub)type declaration within a
226 predicate function. Invariant checks do not apply to these, and
227 the expansion of the procedure will happen in the wrong scope,
228 leading to misplaced freeze nodes.
230 2017-05-02 Ed Schonberg <schonberg@adacore.com>
232 * exp_util.adb (Insert_Library_Level_Action): Use proper scope
233 to analyze generated actions. If the main unit is a body,
234 the required scope is that of the corresponding unit declaration.
236 2017-05-02 Arnaud Charlet <charlet@adacore.com>
238 * einfo.adb (Declaration_Node): flip branches of
239 an IF statement to avoid repeated negations in its condition;

269 * exp_disp.adb (Set_All_DT_Position, In_Predef_Prim_DT):
270 Refine predicate for the case where the primitive operation
271 is a renaming of equality. An overriding operation that is
272 a user-defined renaming of predefined equality inherits its
273 slot from the overridden operation. Otherwise it is treated
274 as a predefined op and occupies the same predefined slot as
275 equality. A call to it is transformed into a call to its alias,
276 which is the predefined equality. A dispatching call thus uses
277 the proper slot if operation is further inherited and called
278 with class-wide arguments.
280 2017-05-02 Justin Squirek <squirek@adacore.com>
282 * errout.adb (Set_Msg_Text): Add a case to switch the message

315 * exp_ch3.adb (Build_Initialization_Call): Generate a null
316 statement if the initialization call is a null procedure, as
317 can happen with a controlled type with no explicit Initialize
318 procedure, or an array of such.
319 * exp_ch7.adb (Process_Object_Declaration): For a type with
320 controlled components that has a trivial Initialize procedure,
321 insert declaration for finalization counter after object

324 finalization block and attendant declarations if component has
325 a trivial Initialize procedure.
326 (Make_Init_Call): Do not generate a call if controlled type has
327 a trivial Initialize procedure.
329 2017-05-02 Eric Botcazou <ebotcazou@adacore.com>

357 2017-05-02 Gary Dismukes <dismukes@adacore.com>
359 * checks.ads (Null_Exclusion_Static_Checks): Add Boolean
360 parameter Array_Comp to indicate the case of an array object
361 with null-excluding components.
362 * checks.adb (Null_Exclusion_Static_Checks):
363 Call Compile_Time_Constraint_Error instead of
364 Apply_Compile_Time_Constraint_Error in the component case. Also
365 call that when Array_Comp is True, with an appropriate warning for
366 the array component case. Only create an explicit initialization
367 by null in the case of an object of a null-excluding access type
368 (and no longer do that in the component case).
369 * sem_ch3.adb (Check_Component): Add a Boolean parameter
370 Array_Comp defaulted to False. Pass Empty for the Comp
371 actual when calling Null_Exclusion_Static_Checks in the case
372 where Comp_Decl matches Object_Decl, because we don't have a
373 component in that case. In the case of an object or component
374 of an array type, pass True for Array_Comp on the recursive call

379 * s-taprop-linux.adb (Prio_To_Linux_Prio): New function to correctly
380 compute the linux priority from the Ada priority. Call this everywhere
381 required. In particular, the previous version was not doing this
382 computation when setting the ceiling priority in various places. It
383 was just converting to C.int, which results in a ceiling that is off
386 2017-05-02 Ed Schonberg <schonberg@adacore.com>

402 2017-05-02 Ed Schonberg <schonberg@adacore.com>
404 * exp_ch9.adb (Discriminated_Size): Moved to sem_util.
405 * sem_util.ads, sem_util.adb (Discriminated_Size): Predicate moved
406 here from exp_ch9, to recognize objects whose creation requires
407 dynamic allocation, so that the proper warning can be emitted
408 when restriction No_Implicit_Heap_Allocation is in effect.
409 * sem_ch3.adb (Analyze_Object_Declaration): Use Discriminated_Size
410 to emit proper warning when an object that requires dynamic
411 allocation is declared.

492 * exp_attr.adb (Callable, Identity, Terminated): Use Find_Prim_Op
493 to find primitive ops, instead of using an Identifier that will
494 later be looked up. This is necessary because these ops are not

498 2017-05-02 Ed Schonberg <schonberg@adacore.com>
500 * sem_ch6.adb (Fully_Conformant_Expressions): Two entity
501 references are fully conformant if they are both expansions
502 of the discriminant of a protected type, within one of the
503 protected operations. One occurrence may be expanded into a
504 constant declaration while the other is an input parameter to
505 the corresponding generated subprogram.

557 controlling actual in a prefixed call, preserve the original node
558 information if the prefix itself has been rewritten, for ASIS use.
560 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
562 * exp_ch6.adb (Insert_Post_Call_Actions):
563 Code clean up. Insert the post-call actions after an enclosing
564 procedure call when N denotes a function call and appears as an
565 actual parameter in the procedure call.
567 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
569 * freeze.adb (Check_Component_Storage_Order): If there is a clause
570 for the component, also reject the attribute if the component
571 doesn't end on a byte boundary and its scalar storage order is
572 different from that of the enclosing record type.
574 2017-04-28 Javier Miranda <miranda@adacore.com>

608 * sem_util.ads, sem_util.adb (Might_Raise): New function
609 that replaces Is_Exception_Safe, but has the opposite
610 sense. Is_Exception_Safe was missing various cases -- calls inside
611 a pragma Debug, calls inside an 'if' or assignment statement,
612 etc. Might_Raise now walks the entire subtree looking for things
614 * exp_ch9.adb (Is_Exception_Safe): Remove.
615 (Build_Protected_Subprogram_Body): Replace call to
616 Is_Exception_Safe with "not Might_Raise". Misc cleanup (use

656 * sem_prag.adb (Relocate_Pragmas_To_Body): A pragma Warnings
657 that follows an expression function must not be relocated to
658 the generated body, because it applies to the code that follows.
660 2017-04-28 Gary Dismukes <dismukes@adacore.com>
662 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): Test
663 Relaxed_RM_Semantics to avoid having CodePeer issue errors on
664 code that might violate the more stringent checking for 'Access
665 introduced in Ada 2005.
667 2017-04-28 Arnaud Charlet <charlet@adacore.com>
669 * a-cforse.adb: minor style fix in comment.
671 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>

689 * sem_ch6.adb (Freeze_Type_Refs): For an interface conversion
690 node between access types, freeze the designated type as well,
691 so that dispatch table pointers are created in the proper scope,
692 and not in the constructed body of the expression function.
694 2017-04-28 Bob Duff <duff@adacore.com>
696 * alloc.ads (Nodes_Initial): Go back to previous value. The large
697 value makes large compilations faster, but small compilations slower.
699 2017-04-28 Arnaud Charlet <charlet@adacore.com>
701 * sem_util.adb: minor typos in Is_Child_Or_Sibling.
703 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
705 * erroutc.adb (Compilation_Errors): Do not consider info messages

719 2017-04-28 Ed Schonberg <schonberg@adacore.com>
721 * sem_res.adb (In_Instance_Code): New predicate in
722 Valid_Conversion, to determine whether a type conversion appears
723 as (or within) an actual for a formal object. Type conversions
724 in instances are not rechecked in Valid_Conversion because
725 visibility changes between generic location andi instance may
726 lead to spurious errors, but conversions within an actual must be
727 fully checked, and they are not fully resolved when pre-analyzing
730 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
732 * exp_ch6.adb (Expand_N_Extended_Return_Statement): Use
733 New_Copy_Tree instead of Relocate_Node as any subsequent copies
734 of the relocated node will have mangled Parent pointers.
735 * sem_util.adb (Build_NCT_Hash_Tables): Reset both hash
736 tables used in conjunction with entity and itype replication.
737 (Visit_Entity): Rewrite the restriction on which entities

776 components_to_record.
777 (gnu_field_to_gnat): New function.
778 (warn_on_field_placement): Likewise.
779 (components_to_record): Add GNAT_RECORD_TYPE and remove REORDER
780 parameters. Rename local variables and adjust recursive call.

791 * sem_intr.adb, sem_res.adb, sem_util.adb, sem_warn.adb, sprint.adb:
792 For efficiency, cache results of Is_Internal_File_Name and
793 Is_Predefined_File_Name in the Units table. This avoids a lot
794 of repeated text processing.
796 2017-04-27 Emmanuel Briot <briot@adacore.com>
798 * g-comlin.adb (Sort_Sections): remove useless test.

802 * a-cfhase.adb, a-cfhase.ads (=): Generic parameter removed to
803 allow the use of regular equality over elements in contracts.
804 (Formal_Model): Ghost package containing model functions that are
805 used in subprogram contracts.
806 (Current_To_Last): Removed, model functions should be used instead.
807 (First_To_Previous): Removed, model functions should be used instead.
808 (Strict_Equal): Removed, model functions should be used instead.
809 (No_Overlap): Removed, model functions should be used instead.
810 (Equivalent_Keys): Functions over cursors are removed. They were

825 2017-04-27 Ed Schonberg <schonberg@adacore.com>
827 * exp_util.adb (Replace_Entity): The prefix of a 'Result
828 attribute reference in a post- condition is the subprogram to
829 which the condition applies. If the condition is inherited
830 by a type extension, the prefix becomes a reference to the
831 inherited operation, but there is no need to create a wrapper
832 for this operation, because 'Result is expanded independently
833 when elaborating the postconditions.
835 2017-04-27 Bob Duff <duff@adacore.com>
837 * sinput.adb: Minor code cleanup.
838 * namet.adb (Append): Create faster versions of
839 Append(String) and Append(Name_Id) by using slice assignment
841 * sem_util.adb (In_Instance): Speed this up by removing
842 unnecessary tests; Is_Generic_Instance is defined for all
844 * sem_util.ads, sem_util.adb (In_Parameter_Specification):
845 Remove unused function.
846 * alloc.ads (Nodes_Initial): Use a much larger value, because
847 the compiler was spending a lot of time copying the nodes table
848 when it grows. This number was chosen in 1996, so is rather out
849 of date with current memory sizes. Anyway, it's virtual memory.
850 Get rid of Orig_Nodes_...; use Node_... instead.
851 * atree.adb (Lock): Do not release the Nodes tables; it's a
853 Orig_Nodes_ ==> Nodes_
854 * nlists.adb: Orig_Nodes_ ==> Nodes_
855 * g-table.adb: Remove unused "with" clause.
856 * g-table.ads, table.ads: Remove Big_Table_Type, which should
857 not be used by clients.

887 and selected components.
888 * uname.adb (Add_Node_Name): Merge the processing for stubs.

899 of Expand_Dispatching_Call. If the denoted subprogram has a
900 class-wide precondition, this is the only precondition that
901 applies to the call, rather that the class-wide preconditions
902 that may apply to the body that is executed. (This is specified

907 * gnat1drv.adb (Adjust_Global_Switches): Issue
908 a warning in GNATprove mode if the runtime library does not

919 * sem_attr.adb (Analyze_Attribute, case 'Image): In Ada2012 the
920 prefix can be an object reference in which case Obj'Image (X)
921 can only be interpreted as an indexing of the parameterless
922 version of the attribute.
923 * par-ch4.adb (P_Name): An attribute reference can be the prefix of
924 an indexing or a slice operation if the attribute does not require
925 parameters. In Ada2012 'Image also belongs in this category,
926 and A'Image (lo .. hi) is legal and must be parsed as a slice.
928 2017-04-27 Yannick Moy <moy@adacore.com>
930 * exp_ch4.adb: Minor reformatting.
931 * gnat1drv.adb (Adjust_Global_Switches): When in GNATprove mode,

1587 * exp_ch7.adb (Make_Transient_Block): Transient blocks do not need
1588 to manage the secondary stack when an enclosing scope already
1589 performs this functionality (aka relaxed management). Switch
1590 -gnatd.s may be used to force strict management in which case
1591 the block will manage the secondary stack unconditionally. Add
1592 a guard to stop the traversal when encountering a package or a

1597 * sem_res.adb (Resolve_Call): Refine further the handling of
1598 limited views of return types in function calls. If the function
1599 that returns a limited view appears in the current unit,
1600 we do not replace its type by the non-limited view because
1601 this transformation is performed int the back-end. However,
1602 the type of the call itself must be the non-limited view, to
1603 prevent spurious resolution errors.

1607 * einfo,ads, einfo.adb (Class_Wide_Preconds, Class_Wide_Postconds):
1608 Removed, proposed implementation using generics for class-wide
1609 preconditions proved impractical.
1610 (Class_Wide_Clone): New attribute of subprogram. Designates
1611 subprogram created for primitive operations with class-wide
1612 pre/postconditions that contain calls to other primitives. The
1613 clone holds the body of the original primitive, but the
1614 pre/postonditions do not apply to it. The original body is
1615 rewritten as a wrapper for a call to the clone.
1616 (Is_Class_Wide_Clone): New flag to identify a Class_Wide_Clone. If
1617 the flag is set, no code for the corresponding pre/postconditions
1618 is inserted into its body.
1620 2017-04-27 Bob Duff <duff@adacore.com>

1689 * sem_ch12.adb (Analyze_Associations): minor reformatting.
1690 (Check_Fixed_Point_Actual): Do not emit a warning on a fixed
1691 point type actual that has user-defined arithmetic primitives,
1692 when there is a previous actual for a formal package that defines
1693 a fixed-point type with the parent user-defined operator.
1695 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
1697 * checks.adb (Generate_Range_Check): Reinstate part of previous change.

1699 the component type allows range checks.
1701 2017-04-27 Ed Schonberg <schonberg@adacore.com>
1703 * sem_aux.adb (Is_Generic_Formal): Use original node to locate
1704 corresponding declaration, because formal derived types are
1705 rewritten as private extensions.
1707 2017-04-27 Ed Schonberg <schonberg@adacore.com>
1709 * sem_dim.adb (Analyze_Dimension_Binary_Op): Do not check
1710 dimensions of operands if node has been analyzed already, because
1711 previous analysis and dimension checking will have removed the
1712 dimension information from the operands.

1716 * debug.adb: Document the use of switch -gnatd.s.

1795 Fix spelling mistakes.
1797 2017-04-25 Bob Duff <duff@adacore.com>
1799 * types.ads, osint.adb, sinput-c.adb, sinput-d.adb, sinput-l.adb,
1800 * sinput-p.adb: Use regular fat pointers, with bounds checking,
1801 for source buffers. Fix misc obscure bugs.
1802 * sinput.ads, sinput.adb: Use regular fat pointers, with bounds
1803 checking, for source buffers. Modify representation clause for
1804 Source_File_Record as appropriate. Move Source_File_Index_Table
1805 from spec to body, because it is not used outside the body.
1806 Move Set_Source_File_Index_Table into the private part, because
1807 it is used only in the body and in children. Use trickery to
1808 modify the dope in the generic instantiation case. It's ugly,
1809 but not as ugly as the previous method. Fix documentation.
1810 Remove obsolete code.

1826 expander is not active or when index/range checks are suppressed
1828 (Insert_List_After_And_Analyze, Insert_List_Before_And_Analyze):
1829 Remove variants that include a Supress parameter. These routines
1830 are never used, and were introduced before the current scope-based
1831 check suppression method.

1862 completion, if the type is derived from a generic formal type.
1864 2017-04-25 Ed Schonberg <schonberg@adacore.com>

1882 scn.ads, gnatls.adb: Eliminate the vestigial Internal_Source_File and
1883 the Internal_Source buffer. This removes the incorrect call to "="
1884 the customer noticed.
1885 Wrap remaining calls to "=" in Null_Source_Buffer_Ptr. We
1886 eventually need to eliminate them altogether. Or else get rid
1887 of zero-origin addressing.

2171 further expansion for the unchecked union.
2172 (Expand_Attribute_Reference, case 'Write): If the type is
2173 an unchecked_union, check whether enclosing scope is a Write
2174 subprogram. Replace attribute with a Raise_Program_Error if the
2175 discriminants of the unchecked_union type have not default values
2176 because such a use is erroneous..

2264 operand as universal real when the operand is a multiplication
2265 or a division where both operands are of any fixed type.
2266 (Unique_Fixed_Point_Type): Add local variable ErrN. Improve the

2396 to return if an interface type is encountered and add
2397 condition to convert the formal parameter to its class-wide
2398 counterpart if Work_Typ is abstract.

2420 * sem_ch3.adb (Derive_Subprogram): Implement rule in RM 6.1.1
2421 (10-15): if derived type T with progenitors is abstract,
2422 and primitive P of this type inherits non-trivial classwide
2423 preconditions from both a parent operation and from an interface
2424 operation, then the inherited operation is abstract if the parent
2425 operation is not null.
2426 * sem_disp.ads, sem_disp.adb: replace function Covers_Some_Interface
2427 with Covered_Interface_Op to yield the actual interface operation
2428 that is implemented by a given inherited operation.

2466 * a-numeri.ads: Change the encoding of Greek letter Pi from
2467 brackets encoding to UTF-8. Use pragma Wide_Character_Encoding
2468 to indicate the encoding. We considered using a byte order mark
2469 (BOM), but that causes various trouble (misc software eats the
2470 BOM, if you have a patch with a BOM, then it's not at the start
2471 of the patch, so it's not a BOM, the BOM affects with-ing files,

2565 Ignore_SPARK_Mode_Pragmas_In_Instance.
2566 * sem_ch6.adb (Analyze_Subprogram_Body_Helper):
2567 Save and restore the value of global flag
2568 Ignore_SPARK_Mode_Pragmas_In_Instance. Set or reinstate the value
2569 of global flag Ignore_SPARK_Mode_Pragmas_In_Instance when either
2570 the corresponding spec or the body must ignore all SPARK_Mode
2571 pragmas found within.
2572 (Analyze_Subprogram_Declaration): Mark
2573 the spec when it needs to ignore all SPARK_Mode pragmas found
2574 within to allow the body to infer this property in case it is
2575 instantiated or inlined later.
2576 * sem_ch7.adb (Analyze_Package_Body_Helper): Save and restore the
2577 value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Set
2578 the value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance
2579 when the corresponding spec also ignored all SPARK_Mode pragmas
2581 (Analyze_Package_Declaration): Mark the spec when
2582 it needs to ignore all SPARK_Mode pragmas found within to allow
2583 the body to infer this property in case it is instantiated or
2585 * sem_ch12.adb (Analyze_Formal_Package_Declaration):
2586 Save and restore the value of flag
2587 Ignore_SPARK_Mode_Pragmas_In_Instance. Mark the
2588 formal spec when it needs to ignore all SPARK_Mode
2589 pragmas found within to allow the body to infer this
2590 property in case it is instantiated or inlined later.
2591 (Analyze_Package_Instantiation): Save and restore the value
2592 of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Mark
2593 the instance spec when it needs to ignore all SPARK_Mode
2594 pragmas found within to allow the body to infer this
2595 property in case it is instantiated or inlined later.
2596 (Analyze_Subprogram_Instantiation): Save and restore the value
2597 of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Mark the
2598 instance spec and anonymous package when they need to ignore
2599 all SPARK_Mode pragmas found within to allow the body to infer
2600 this property in case it is instantiated or inlined later.
2601 (Instantiate_Package_Body): Save and restore the value of global
2602 flag Ignore_SPARK_Mode_Pragmas_In_Instance. Set the value of

2610 pragmas found within.
2611 * sem_prag.adb (Analyze_Pragma): Update the reference to
2612 Ignore_Pragma_SPARK_Mode.
2613 * sem_util.adb (SPARK_Mode_Is_Off): A construct which ignored
2614 all SPARK_Mode pragmas defined within yields mode "off".
2616 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
2618 * bindgen.adb, exp_dbug.adb, errout.adb, fname.adb: Minor reformatting.
2620 2017-04-25 Bob Duff <duff@adacore.com>
2622 * exp_atag.adb (Build_CW_Membership): Add "Suppress =>
2623 All_Checks" to avoid generating unnecessary checks.
2624 * exp_ch4.adb (Expand_N_In, Make_Tag_Check): Add "Suppress =>
2626 * sem.ads: Fix comment.
2627 * expander.ads: Fix comment.
2628 * exp_atag.ads: Fix comment: "Index = 0" should be
2631 2017-04-25 Gary Dismukes <dismukes@adacore.com>
2633 * s-taprop-linux.adb: Minor editorial fixes.
2635 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
2637 * sem_util.adb (New_Copy_Tree): Put back the declarations of the
2638 hash tables at library level. Reinstate the NCT_Hash_Tables_Used
2639 variable and set it to True whenever the main hash table is
2640 populated. Short- circuit the Assoc function if it is false
2641 and add associated guards.
2643 2017-04-25 Olivier Hainque <hainque@adacore.com>
2645 * bindgen.adb (Gen_Elab_Calls): Also update counter of lone
2646 specs without elaboration code that have an elaboration counter
2647 nevertheless, e.g. when compiled with -fpreserve-control-flow.
2648 * sem_ch10.adb (Analyze_Compilation_Unit):
2649 Set_Elaboration_Entity_Required when requested to preserve
2650 control flow, to ensure the unit elaboration is materialized at
2651 bind time, resulting in the inclusion of the unit object file
2652 in the executable closure at link time.
2654 2017-04-25 Pierre-Marie de Rodat <derodat@adacore.com>
2656 * exp_dbug.adb: In Debug_Renaming_Declaration,
2657 when dealing with indexed component, accept to produce a renaming
2658 symbol when the index is an IN parameter or when it is a name
2659 defined in an outer scope.
2661 2017-04-25 Yannick Moy <moy@adacore.com>
2663 * errout.adb (Error_Msg): Adapt continuation
2664 message in instantiations and inlined bodies for info messages.
2666 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
2668 * fname.adb (Has_Internal_Extension): Add pragma Inline.
2669 Use direct 4-character slice comparisons.
2671 pragma Inline. (Has_Suffix): Delete.
2672 (Is_Internal_File_Name):
2673 Test Is_Predefined_File_Name first.
2674 (Is_Predefined_File_Name):
2675 Use direct slice comparisons as much as possible and limit all
2676 comparisons to at most 8 characters.
2678 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
2680 * checks.adb (Insert_Valid_Check): Code cleanup.
2681 * exp_ch6.adb (Add_Validation_Call_By_Copy_Code): New routine.
2682 (Expand_Actuals): Generate proper copy-back for a validation
2683 variable when it acts as the argument of a type conversion.
2684 * sem_util.adb (Is_Validation_Variable_Reference): Augment the
2685 predicate to operate on type qualifications.
2687 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
2689 * sem_prag.adb, exp_ch6.adb, binde.adb, sem_disp.adb, s-fileio.adb:
2692 2017-04-25 Bob Duff <duff@adacore.com>
2694 * sem_prag.adb (No_Return): Give an error if the pragma applies
2695 to a body. Specialize the error for the specless body case,
2696 as is done for (e.g.) pragma Convention.
2697 * debug.adb: Add switch -gnatd.J to disable the above legality
2698 checks. This is mainly for use in our test suite, to avoid
2699 rewriting a lot of illegal (but working) code. It might also
2700 be useful to customers. Under this switch, if a pragma No_Return
2701 applies to a body, and the procedure raises an exception (as it
2702 should), the pragma has no effect. If the procedure does return,
2703 execution is erroneous.
2705 2017-04-25 Bob Duff <duff@adacore.com>
2707 * exp_ch6.adb (Expand_Actuals): This is the
2708 root of the problem. It took N as an 'in out' parameter, and in
2709 some cases, rewrote N, but then set N to Original_Node(N). So
2710 the node returned in N had no Parent. The caller continued
2711 processing of this orphaned node. In some cases that caused a
2712 crash (e.g. Remove_Side_Effects climbs up Parents in a loop,
2713 and trips over the Empty Parent). The solution is to make N an
2714 'in' parameter. Instead of rewriting it, return the list of
2715 post-call actions, so the caller can do the rewriting later,
2716 after N has been fully processed.
2717 (Expand_Call_Helper): Move most of Expand_Call here. It has
2718 too many premature 'return' statements, and we want to do the
2719 rewriting on return.
2720 (Insert_Post_Call_Actions): New procedure to insert the post-call
2721 actions in the appropriate place. In the problematic case,
2722 that involves rewriting N as an Expression_With_Actions.
2723 (Expand_Call): Call the new procedures Expand_Call_Helper and
2724 Insert_Post_Call_Actions.
2726 2017-04-25 Ed Schonberg <schonberg@adacore.com>
2728 * sem_prag.adb (Inherits_Class_Wide_Pre): Cleanup code, handle
2729 properly type derived from generic formal types, to handle
2730 properly modified version of ACATS 4.1B B611017.
2732 2017-04-25 Javier Miranda <miranda@adacore.com>
2734 * exp_unst.adb (Subp_Index): Adding missing
2735 support for renamings and functions that return a constrained
2736 array type (i.e. functions for which the frontend built a
2737 procedure with an extra out parameter).
2739 2017-04-25 Pascal Obry <obry@adacore.com>
2741 * s-string.adb: Minor code clean-up.
2743 2017-04-25 Bob Duff <duff@adacore.com>

2748 function for Non_Blocking_Wait_Process.
2750 2017-04-25 Bob Duff <duff@adacore.com>
2752 * prep.adb (Preprocess): Remove incorrect
2753 Assert. Current character can be ASCII.CR.
2755 2017-04-25 Ed Schonberg <schonberg@adacore.com>
2757 * sem_prag.adb (Set_Convention_From_Pragma): Cleanup code for
2758 convention Stdcall, which has a number of exceptions. Convention
2759 is legal on a component declaration whose type is an anonymous
2760 access to subprogram.
2762 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
2764 * sem_ch4.adb: sem_ch4.adb Various reformattings.
2765 (Try_One_Prefix_Interpretation): Use the base type when dealing
2766 with a subtype created for purposes of constraining a private
2767 type with discriminants.
2769 2017-04-25 Javier Miranda <miranda@adacore.com>

2773 dispatching primitives (Restore_Warnings): Restore warning on
2774 late dispatching primitives (Save_Warnings): Save warning on late
2775 dispatching primitives (Do_Warning_Switch): Use -gnatw.j/-gnatw.J
2776 to enable/disable this warning.
2777 (WA_Warnings): Set warning on late dispatching primitives.
2778 * sem_ch3.adb (Analyze_Private_Extension_Declaration): Remember
2779 that its parent type has a private extension.
2780 * sem_disp.adb (Warn_On_Late_Primitive_After_Private_Extension):
2782 * usage.adb: Document -gnatw.j and -gnatw.J.
2784 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
2786 * exp_ch7.adb, checks.adb, sem_prag.adb, eval_fat.adb: Minor
2789 2017-04-25 Bob Duff <duff@adacore.com>
2791 * binde.adb (Validate): Do not pass dynamic strings
2792 to pragma Assert, because older compilers do not support that.
2794 2017-04-25 Bob Duff <duff@adacore.com>
2796 * s-fileio.adb (Close): When a temp file is
2797 closed, delete it and clean up its Temp_File_Record immediately,
2798 rather than waiting until later.
2799 (Temp_File_Record): Add File
2800 component, so Close can know which Temp_File_Record corresponds
2801 to the file being closed.
2802 (Delete): Don't delete temp files,
2803 because they are deleted by Close.
2804 (Open): Set the File component
2805 of Temp_File_Record. This requires moving the creation of the
2806 Temp_File_Record to the end, after the AFCB has been created.
2808 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
2810 * checks.adb (Insert_Valid_Check): Do not generate
2811 a validity check when inside a generic.
2813 2017-04-25 Yannick Moy <moy@adacore.com>
2815 * sem_res.adb (Resolve_Type_Conversion): Fix bad logic.
2817 2017-04-25 Arnaud Charlet <charlet@adacore.com>
2819 * snames.ads-tmpl (Snames): More names for detecting predefined
2820 potentially blocking subprograms.
2822 2017-04-25 Ed Schonberg <schonberg@adacore.com>
2824 * sem_prag.adb (Analyze_Pre_Post_Condition): The rules
2825 concerning inheritance of class-wide preconditions do not apply
2828 2017-04-25 Bob Duff <duff@adacore.com>
2830 * s-ficobl.ads: Minor comment fix.
2832 2017-04-25 Yannick Moy <moy@adacore.com>
2834 * checks.adb (Apply_Scalar_Range_Check): Analyze precisely
2835 conversions from float to integer in GNATprove mode.
2836 (Apply_Type_Conversion_Checks): Make sure in GNATprove mode
2837 to call Apply_Type_Conversion_Checks, so that range checks
2838 are properly positioned when needed on conversions, including
2839 when converting from float to integer. (Determine_Range): In
2840 GNATprove mode, take into account the possibility of conversion
2841 from float to integer.
2842 * sem_res.adb (Resolve_Type_Conversion): Only enforce range
2843 check on conversions from fixed-point to integer, not anymore
2844 on conversions from floating-point to integer, when in GNATprove
2847 2017-04-25 Yannick Moy <moy@adacore.com>
2849 * checks.adb (Determine_Range_R): Special case type conversions
2850 from integer to float in order to get bounds in that case too.
2851 * eval_fat.adb (Machine): Avoid issuing warnings in GNATprove
2852 mode, for computations involved in interval checking.

2864 (Validated_Object): New routine along with pragma Inline.
2865 (Set_Validated_Object): New routine along with pragma Inline.
2866 * exp_attr.adb (Make_Range_Test): Add processing for validation
2867 variables to avoid extra reads and copies of the prefix.
2868 * exp_ch6.adb (Expand_Actuals): Add copy-back for validation
2869 variables in order to reflect any changes done in the variable
2870 back into the original object.
2871 * sem_util.adb (Is_Validation_Variable_Reference): New routine.
2872 * sem_util.ads (Is_Validation_Variable_Reference): New routine.

2878 generate Finalize_Address routines for CodePeer.
2880 2017-04-25 Ed Schonberg <schonberg@adacore.com>
2882 * sem_prag.adb (Inherits_Class_Wide_Pre): subsidiary of
2883 Analyze_Pre_Post_Condition, to implement the legality checks
2884 mandated by AI12-0131: Pre'Class shall not be specified for an
2885 overriding primitive subprogram of a tagged type T unless the
2886 Pre'Class aspect is specified for the corresponding primitive
2887 subprogram of some ancestor of T.
2889 2017-04-25 Bob Duff <duff@adacore.com>
2891 * sem_ch8.adb (Use_One_Type): If a use_type_clause
2892 is redundant, set its Used_Operations to empty. This is only
2893 necessary for use clauses that appear in the parent of a generic
2894 child unit, because those use clauses get reanalyzed when we
2895 instantiate the generic, and we don't want the Used_Operations
2896 carried over from the original context (where it was probably
2899 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
2901 * exp_ch6.adb: Minor reformatting.

2909 * par.adb (Par): Null out Current_Source_File, to ensure that
2910 the above bugs won't rear their ugly heads again.
2912 2017-04-25 Ed Schonberg <schonberg@adacore.com>
2914 * sem_ch8.adb (Find_Type): For an attribute reference
2915 'Class, if prefix type is synchronized and previous errors
2916 have suppressed the creation of the corresponding record type,
2917 create a spurious class-wide for the synchonized type itself,
2918 to catch other misuses of the attribute
2920 2017-04-25 Steve Baird <baird@adacore.com>
2922 * exp_ch6.adb (Expand_Simple_Function_Return): if CodePeer_Mode

2926 if CodePeer_Mode is True, then don't generate the
2927 tag checks for the result of call to an instance of
2928 Ada.Tags.Generic_Dispatching_Constructor (i.e., both the "is a
2929 descendant of" check and the accessibility check).
2931 2017-04-25 Ed Schonberg <schonberg@adacore.com>
2933 * sem_ch13.adb: Code cleanups.
2934 * a-strbou.ads: minor whitespace fix in Trim for bounded strings.

2939 * exp_ch4.adb (Library_Level_Target): New function.
2940 (Expand_Concatenate): When optimization is enabled, also expand
2941 the operation out-of-line if the concatenation is present within
2942 the expression of the declaration of a library-level object and
2943 not only if it is the expression of the declaration.
2945 2017-04-25 Bob Duff <duff@adacore.com>
2947 * freeze.adb (Freeze_Object_Declaration): Do
2948 not Remove_Side_Effects if there is a pragma Linker_Section,
2949 because in that case we want static initialization in the
2950 appropriate section.
2952 2017-04-25 Gary Dismukes <dismukes@adacore.com>
2954 * exp_dbug.adb: Minor rewording and reformatting.

2959 handle the proposed changes to rules concerning potentially
2960 unevaluated expressions, to include selected components that
2961 do not depend on discriminants, and indexed components with
2963 * sem_util.adb (Is_Potentially_Unevaluated): Add check for
2964 predicate in quantified expression, and fix bugs in the handling
2965 of case expressions and membership test.
2966 (Analyze_Attribute_Old_Result): use new predicate.
2967 (Analyze_Attribute, case Loop_Entry): ditto.
2969 2017-04-25 Bob Duff <duff@adacore.com>
2971 * s-secsta.adb (SS_Info): Add a comment
2972 explaining why we don't need to walk all the chunks in order to
2973 compute the total size.
2975 2017-04-25 Bob Duff <duff@adacore.com>
2977 * namet.ads, namet.adb (Global_Name_Buffer): Increase the length
2978 of the global name buffer to 4*Max_Line_Length.
2980 2017-04-25 Javier Miranda <miranda@adacore.com>
2982 * exp_ch8.adb (Expand_N_Object_Renaming_Declaration): When creating a
2983 renaming entity for debug information, mark the entity as needing debug
2984 info if it comes from sources.
2986 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
2988 * sem_ch13.adb (Analyze_Attribute_Definition_Clause): Remove the
2989 restriction converning the use of 'Address where the prefix is
2990 of a controlled type.
2992 2017-04-25 Pierre-Marie de Rodat <derodat@adacore.com>

3008 internal calls that appear in preconditions of protected
3009 operations, in default values for same, and in contract guards
3010 for contract cases in SPARK.

3021 * a-numaux-x86.ads: Fix package description.
3022 * a-numaux-x86.adb (Is_Nan): Minor tweak.

3031 on analysis of prefix whose type is a current instance of a
3032 synchronized type, but where the prefix itself is an entity that

3037 * exp_ch5.adb (Replace_Target): When rewriting the RHS, preserve
3038 the identity of callable entities therein, because they have been
3039 properly resolved, and prefixed calls may have been rewritten
3042 2017-04-25 Patrick Bernardi <bernardi@adacore.com>
3044 * exp_ch3.adb (Build_Init_Statements): Convert
3045 the expression of the pragma/aspect Secondary_Stack_Size to
3046 internal type System.Parameters.Size_Type before assigning
3047 it to the Secondary_Stack_Size component of the task type's
3048 corresponding record.
3050 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
3052 * sem_eval.adb (Compile_Time_Compare): Reinstate the expr+literal
3053 (etc) optimizations when the type is modular and the offsets
3056 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
3058 * s-osinte-freebsd.ads: Minor comment tweaks
3060 2017-04-25 Javier Miranda <miranda@adacore.com>
3062 * urealp.adb (UR_Write): Reverse previous patch
3063 adding documentation on why we generate multiplications instead
3064 of divisions (needed to avoid expressions whose computation with
3065 large numbers may cause division by 0).
3067 2017-04-25 Bob Duff <duff@adacore.com>
3069 * erroutc.adb (Set_Specific_Warning_Off,
3070 Set_Warnings_Mode_Off): Use the correct source file for
3071 Stop. Was using Current_Source_File, which is only valid during
3072 parsing. Current_Source_File will have a leftover value from
3073 whatever file happened to be parsed last, because of a with_clause
3076 2017-04-25 Bob Duff <duff@adacore.com>
3078 * lib.ads, lib.adb (In_Internal_Unit): New functions similar
3079 to In_Predefined_Unit, but including GNAT units.
3080 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): Replace
3081 with Should_Ignore_Pragma_Par and Should_Ignore_Pragma_Sem,
3082 because Should_Ignore_Pragma was not working reliably outside
3083 the parser, because Current_Source_File is not valid.
3084 * sem_prag.adb, exp_prag.adb: Call Should_Ignore_Pragma_Sem.
3085 * par-prag.adb: Call Should_Ignore_Pragma_Par.

3124 Remove refactored calls and integrated code from
3125 Add_Parent_Invariants and Add_Interface_Invariants.
3127 2017-04-25 Johannes Kanig <kanig@adacore.com>
3129 * errout.adb (Output_Messages): Adjust computation of total
3131 * erroutc.adb (Error_Msg): In statistics counts, deal

3152 2017-04-25 Ed Schonberg <schonberg@adacore.com>
3154 * sem_ch4.adb (Analyze_Selected_Component): Refine analysis
3155 of prefix whose type is a current instance of a synchronized
3156 type. If the prefix is an object this is an external call (or
3157 requeue) that can only access public operations of the object. The
3158 previous predicate was too restrictive, and did not allow public
3159 protected operations, only task entries.
3161 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
3163 * sem_ch5.adb, fname.adb: Minor reformatting.
3165 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
3167 * einfo.adb (Is_Anonymous_Access_Type): New routine.
3168 * einfo.ads Update the placement of
3169 E_Anonymous_Access_Subprogram_Type along with all subtypes that
3171 (Is_Anonymous_Access_Type): New routine.
3172 * exp_ch7.adb (Allows_Finalization_Master): Do not generate a
3173 master for an access type subject to pragma No_Heap_Finalization.
3174 * exp_util.adb (Build_Allocate_Deallocate_Proc): An object being
3175 allocated or deallocated does not finalization actions if the
3176 associated access type is subject to pragma No_Heap_Finalization.
3177 * opt.ads Add new global variable No_Heap_Finalization_Pragma.
3178 * par-prag.adb Pragma No_Heap_Finalization does not need special
3179 processing from the parser.
3180 * sem_ch6.adb (Check_Return_Subtype_Indication): Remove ancient
3181 ??? comments. Use the new predicate Is_Anonymous_Access_Type.
3182 * sem_prag.adb Add an entry in table Sig_Flags for pragma
3183 No_Heap_Finalization.
3184 (Analyze_Pragma): Add processing for
3185 pragma No_Heap_Finalization. Update various error messages to
3186 use Duplication_Error.
3187 * sem_util.ads, sem_util.adb (No_Heap_Finalization): New routine.
3188 * snames.ads-tmpl: Add new predefined name No_Heap_Finalization
3189 and corresponding pragma id.
3191 2017-04-25 Bob Duff <duff@adacore.com>
3193 * freeze.adb (Freeze_Record_Type): Use the
3194 underlying type of the component type to determine whether it's
3195 elementary. For representation clause purposes, a private type
3196 should behave the same as its full type.
3197 * fname.ads, fname.adb (Is_Predefined_File_Name):
3198 Make sure things like "system.ali" are recognized as predefined.
3200 2017-04-25 Javier Miranda <miranda@adacore.com>

3206 * sem_ch5.adb (Preanalyze_Range): Handle properly an Ada2012
3207 element iterator when the name is an overloaded function call,
3208 one of whose interpretations yields an array.
3210 2017-04-25 Bob Duff <duff@adacore.com>
3212 * uname.ads, uname.adb (Is_Predefined_Unit_Name,
3213 Is_Internal_Unit_Name): New functions for operating on unit
3214 names, as opposed to file names. There's some duplicated code
3215 with fname.adb, which is unfortunate, but it seems like we don't
3216 want to add dependencies here.
3217 * fname-uf.adb (Get_File_Name): Change Is_Predefined_File_Name
3218 to Is_Predefined_Unit_Name; the former was wrong, because Uname
3219 is not a file name at all.
3220 * fname.ads, fname.adb: Document the fact that
3221 Is_Predefined_File_Name and Is_Internal_File_Name can be called
3222 for ALI files, and fix the code so it works properly for ALI
3223 files. E.g. these should return True for "system.ali".
3225 2017-04-25 Justin Squirek <squirek@adacore.com>
3227 * exp_util.adb (Add_Invariant): Removed,
3228 code moved to Add_Invariant_Check, Add_Inherited_Invariant,
3229 and Add_Own_Invariant. (Add_Invariant_Check): Used
3230 for adding runtime checks from any kind of invariant.
3231 (Add_Inherited_Invariant): Generates invariant checks for
3232 class-wide invariants (Add_Interface_Invariants): Removed, code
3233 moved to Build_Invariant_Procedure_Body (Add_Own_Invariant):

3236 (Build_Invariant_Procedure_Body): Add refactored calls
3237 and integrated code from Add_Parent_Invariants and
3238 Add_Interface_Invariants.
3239 (Process_Type): Removed, the
3240 relavant code was inlined into both Add_Own_Invariant and
3241 Add_Inherited_Invariant.

3262 and Build_Invariant_Procedure_Declaration.
3263 * exp_util.ads, exp_util.adb Add Build_Invariant_Procedure_Body
3264 and Build_Invariant_Procedure_Declaration from exp_ch7
3265 and break-out Is_Untagged_Private_Derivation from
3266 Build_Invariant_Procedure_Body.
3267 (Replace_Type_References):
3268 Append an extra parameter to allow for dispatching replacements
3269 and add the corrasponding logic.
3270 (Type_Invariant): Remove
3271 Replace_Typ_Refs and replace its references with calls to
3272 Replace_Type_References.
3273 * sem_ch3.adb, sem_prag.adb: Remove with and use of exp_ch7.
3275 2017-04-25 Bob Duff <duff@adacore.com>
3277 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): New function
3278 that returns True when appropriate.
3279 * par-prag.adb, exp_prag.adb, sem_prag.adb: Do not ignore pragmas
3280 when compiling predefined files.
3281 * fname.ads, fname.adb (Is_Predefined_File_Name): Fix bug:
3282 "gnat.adc" should not be considered a predefined file name.
3283 That required (or at least encouraged) a lot of cleanup of global
3284 variable usage. We shouldn't be communicating information via
3285 the global name buffer.
3286 * bindgen.adb, errout.adb, fname-uf.adb, lib-load.adb, make.adb,
3287 * restrict.adb, sem_ch10.adb, sem_ch6.adb, sem_ch8.adb: Changes

3307 * stringt.ads, stringt.adb, exp_dbug.adb, sem_dim.adb: Remove
3308 Add_String_To_Name_Buffer, to avoid using the global Name_Buf.
3309 Add String_To_Name with no side effects.

3346 * sem_ch5.adb (Analyze_Assignment): Reset Full_Analysis flag on
3347 the first pass over an assignment statement with target names,
3348 to prevent the generation of subtypes (such as discriminated

3366 For_Freeze. Add local variable Build_Body. Inherited DIC pragmas
3367 are now only processed when freezing occurs. Build a body only

3384 properties of the private type to the full view in case the full
3385 view derives from a parent type and inherits a DIC pragma.
3386 * sem_prag.adb (Analyze_Pragma): Guard against a case where a
3387 DIC pragma is placed at the top of a declarative region.
3389 2017-04-25 Arnaud Charlet <charlet@adacore.com trojanek>

3397 the error message when the attribute reference is an actual in
3398 a call to a subprogram inherited from a generic formal type with
3399 unknown discriminants, which makes the subprogram and its formal
3400 parameters intrinsic (see RM 6.3.1 (8) and (13)).

3410 recursive Compute_Type_Key to protect against fetching the source
3411 code for Standard, in case a component of the type is declared

3434 * sem_prag.adb (Process_Inline): Set Body_Needed_For_Inlining if
3435 context is a package declaration.

4116 (Remove_Extra_Clauses): New routine.
4117 (Report_Extra_Clauses): Remove the detection of ... => null

4176 subsidiary to Expand_N_Object_ Declaration, to compute a guard on
4177 an object declaration for an array type with a modular index type
4178 with the size of Long_Long_Integer. Special processing is needed
4179 in this case to compute reliably the size of the object, and
4180 eventually to raise Storage_Error, when wrap-around arithmetic
4181 might compute a meangingless size for the object.
4183 2017-01-23 Justin Squirek <squirek@adacore.com>

4190 * sem_res.adb (Resolve_Call): In the part of the code where
4191 it is deciding whether to turn the call into an indexed
4192 component, avoid doing so if the call is to an instance of

4194 indexed component, and resolution of that turns it back into a
4195 function call, and so on, resulting in infinite recursion.

4302 called function is in the extended main unit then no action is
4303 needed since the back-end handles this case.

4576 now done by Analyze_Declarations.
4577 * sem_disp.adb (Check_Dispatching_Operation): DIC and Invariant
4578 procedures are never treated as primitives.
4580 2017-01-19 Yannick Moy <moy@adacore.com>
4582 * frontend.adb: Analyze inlined bodies and check elaboration
4583 rules in GNATprove mode too.
4584 * sem_elab.adb (Delay_Element): Add Boolean component to save
4585 indication that call is in SPARK code. (Check_Elab_Calls):
4586 Check elaboration rules in GNATprove mode, and correctly set
4587 the current value of SPARK_Mode.

4589 (Add_SPARK_Xrefs): Simplify iteration over dereferences.
4591 2017-01-19 Ed Schonberg <schonberg@adacore.com>
4593 * exp_ch4.adb (Expand_Concatenate): Do no enable overflow
4594 checks on the expression for the high bound of concatenation
4595 when checks are disabled, to suppress warnings about potential
4596 constraint errors in restricted runtimes.
4598 2017-01-19 Hristian Kirtchev <kirtchev@adacore.com>
4600 * exp_ch3.adb (Expand_Freeze_Enumeration_Type): Mark the
4601 representation-to-position function as inlined.
4602 * sem_cat.adb (Set_Categorization_From_Scope): Do not modify
4603 the purity of an internally generated entity if it has been
4604 explicitly marked as pure for optimization purposes.
4605 * exp_aggr.adb: Minor reformatting.
4607 2017-01-19 Javier Miranda <miranda@adacore.com>
4609 * exp_ch6.adb (Expand_Call): Remove side effects on
4610 actuals that are allocators with qualified expression since the
4611 initialization of the object is performed by means of individual
4612 statements (and hence it must be done before the call).
4614 2017-01-19 Ed Schonberg <schonberg@adacore.com>
4616 * sem_ch3.adb (Analyze_Declarations): Minor reformatting.
4617 (Build_Derived_Enumeration_Type): If the derived type inherits a
4618 dynamic predicate from its parent, the bounds of the type must
4619 freeze because an explicit constraint is constructed for the
4620 type and the corresponding range is elaborated now.
4622 2017-01-19 Arnaud Charlet <charlet@adacore.com>
4624 * sem_attr.ads: minor fix of inconsistent casing in comment
4625 * lib-writ.ads: minor align comments in columns
4626 * sem_ch3.adb: Minor reformatting.
4627 * spark_xrefs.ads: minor fix typo in SPARK-related comment
4628 * table.ads: minor style fix in comment
4629 * lib-xref-spark_specific.adb
4630 (Add_SPARK_Xrefs): simplify processing of SPARK cross-references.
4631 * sem_ch12.adb: minor whitespace fix
4632 * freeze.adb: Add comment.
4633 * sem_util.adb (Unique_Name): for instances of
4634 generic subprograms ignore the name of the wrapper package.
4636 2017-01-19 Javier Miranda <miranda@adacore.com>
4638 * exp_aggr.adb (Resolve_Record_Aggregate):
4639 Factorize code needed for aggregates of limited and unlimited
4640 types in a new routine.
4641 (Pass_Aggregate_To_Back_End): New subprogram.
4643 2017-01-19 Yannick Moy <moy@adacore.com>

4647 2017-01-19 Ed Schonberg <schonberg@adacore.com>
4649 * sem_ch4.ads, sem_ch4.adb (Try_Object_Operation): Make subprogram
4650 public, for use elsewhere.
4651 * sem_ch6.adb (Analyze_Procedure_Call): In SPARK_Mode and within
4652 an Inlined_body, recognize a call that uses object notation
4653 and has not been rewritten as a regular call because regular
4654 expansion has not taken place.
4656 2017-01-19 Bob Duff <duff@adacore.com>
4658 * checks.adb (Apply_Type_Conversion_Checks): Disable small optimization
4659 in case of generic formal discrete types, because it causes crashes in
4660 the compiler when built with assertions on.
4662 2017-01-19 Hristian Kirtchev <kirtchev@adacore.com>
4664 * lib-xref-spark_specific.adb, sem_util.adb, sem_util.ads,

4667 2017-01-19 Bob Duff <duff@adacore.com>
4669 * bcheck.adb (Check_Consistent_Dynamic_Elaboration_Checking):
4670 Increment Warnings_Detected. It was decrementing, which is
4671 wrong since we just issued a warning message.
4672 * binderr.ads (Errors_Detected, Warnings_Detected): Declare
4673 these variables to be of subtype Nat instead of Int, because
4674 they should never be negative.
4676 2017-01-19 Javier Miranda <miranda@adacore.com>
4678 * contracts.adb (Build_Postconditions_Procedure): Replace
4679 Generate_C_Code by Modify_Tree_For_C.

4689 by Modify_Tree_For_C.
4690 * exp_util.adb (Remove_Side_Effects, Side_Effect_Free): Replace
4691 Generate_C_Code by Modify_Tree_For_C.
4692 * sem_res.adb (Resolve_Type_Conversion): Replace Generate_C_Code
4693 by Modify_Tree_For_C.
4694 * sinfo.ads (Modify_Tree_For_C): Adding documentation.
4696 2017-01-19 Javier Miranda <miranda@adacore.com>
4698 * sem_util.ads, sem_util.adb (Expression_Of_Expression_Function): New
4700 (Is_Inlinable_Expression_Function): New subprogram.
4701 * exp_ch6.ads, exp_ch6.adb (Expression_Of_Expression_Function): Moved
4703 (Is_Inlinable_Expression_Function): Moved to Sem_Util.
4705 2017-01-19 Ed Schonberg <schonberg@adacore.com>
4707 * sem_ch4.adb (Diagnose_Call): Improve error message when a
4708 selected component has a prefix that might be interpreted
4709 as a parameterless function call, but none of the candidate
4710 interpretations is parameterless, and there is a hidden homonym
4711 of the prefix that is a package.
4712 * sem_ch8.adb (Find_Selected_Component): If the prefix might be
4713 interpreted as a parameterless function call and its analysis
4714 fails, do not call Analyze_Selected_Component.
4716 2017-01-19 Steve Baird <baird@adacore.com>
4718 * sem_util.ads: Add new Use_Full_View Boolean parameter to
4720 * sem_util.adb (Get_Index_Bounds): replace calls to Scalar_Range with
4721 calls to a newly-defined Scalar_Range_Of_Right_View function.
4723 2017-01-19 Arnaud Charlet <charlet@adacore.com>
4725 * gnat1drv.adb: minor fix of unbalanced parens in comment
4726 * lib-xref.ads (Traverse_Compilation_Unit): declaration moved
4727 to visible part of the package to allow re-use in GNATprove.
4728 * lib-xref-spark_specific.adb (Traverse_Stub): routine refactored
4729 from repeated code of Traverse_Compilation_Unit.
4730 (Traverse_Declaration_Or_Statement): fixed detection of
4731 generic subprograms and packages; also, iteration over case
4732 statement alternatives rewritten to avoid testing if the first
4733 alternative is present (since it must be present due to Ada
4734 syntax restrictions).
4736 2017-01-19 Hristian Kirtchev <kirtchev@adacore.com>
4738 * exp_ch6.adb (Expand_N_Subprogram_Body): Mark the spec as
4739 returning by reference not just for subprogram body stubs,
4740 but for all subprogram cases.
4741 * sem_util.adb: Code reformatting.
4742 (Requires_Transient_Scope): Update the call to Results_Differ.
4743 (Results_Differ): Update the parameter profile and the associated
4746 2017-01-19 Ed Schonberg <schonberg@adacore.com>
4748 * sem_dim.adb (Analyze_Dimension): Analyze object declaration and
4749 identifier nodes that do not come from source, to handle properly
4750 dimensionality check within an inlined body which inclddes both
4751 original operands and rewritten operands. This removes spurious
4752 dimensionality errors in the presence of front-end inlining,
4753 as well as in SPARK mode.
4755 2017-01-16 Jakub Jelinek <jakub@redhat.com>
4758 * gcc-interface/lang.opt (gant, gnatO, gnat): Add Driver flag.

4791 2017-01-13 Ed Schonberg <schonberg@adacore.com>
4793 * einfo.ads: minor grammar fixes in comment of Normalized_Position_Max.
4794 * scil_ll.adb: Minor style fix in comment.
4795 * sem_ch8.adb (Analyze_Expanded_Name): Perform dimension analysis
4796 even if entity is already set, because the node may be renalyzed
4797 after inlining transformations.
4799 2017-01-13 Javier Miranda <miranda@adacore.com>
4801 * sem_res.adb (Resolve_Call): Do not establish a transient scope
4802 for a call to inlinable expression function (since the call will
4803 be replaced by its returned object).
4804 * exp_ch6.ads (Is_Inlinable_Expression_Function): New subprogram.

4806 (Expand_Call): For inlinable expression function call replace the
4807 call by its returned object.
4808 (Is_Inlinable_Expression_Function): New subprogram.
4810 2017-01-13 Gary Dismukes <dismukes@adacore.com>

4817 (Copy_Original_Specification): Removed.
4818 (Skip_Contract_Only_Subprogram): Move here checks previously
4819 located in the caller of this routine (to leave the code more clean).
4820 (Build_Contract_Only_Subprogram): Code cleanup.
4821 * scil_ll.ads, scil_ll.adb (Get_Contract_Only_Body_Name): Removed.
4822 (Get_Contract_Only_Missing_Body_Name): Removed.
4824 2017-01-13 Javier Miranda <miranda@adacore.com>
4826 * sem_ch6.adb (Cloned_Expression): New subprogram.
4827 (Freeze_Expr_Types): Complete previous patch since the expression
4828 of an expression-function may have iterators and loops with
4829 defining identifiers which, as part of the preanalysis of the
4830 expression, may be left decorated with itypes that will not be
4831 available in the tree passed to the backend.
4833 2017-01-13 Ed Schonberg <schonberg@adacore.com>
4835 * checks.adb (Apply_Type_Conversion_Checks): Optimize a type
4836 conversion to Integer of an expression that is an attribute
4837 reference 'Pos on an enumeration type.
4839 2017-01-13 Bob Duff <duff@adacore.com>

4846 calls in accessibility check on return statement.
4848 2017-01-13 Hristian Kirtchev <kirtchev@adacore.com>
4850 * sem_ch6.adb (Analyze_Subprogram_Body_Helper):
4851 Ensure that the input body is a subprogram body before trying to
4852 determine whether it denoted an expression function. Note that
4853 subprogram body stubs cannot denote expression functions.
4855 2017-01-13 Gary Dismukes <dismukes@adacore.com>
4857 * bindgen.adb, sem_ch6.adb, binde.adb, exp_ch3.adb: Minor reformatting
4860 2017-01-13 Javier Miranda <miranda@adacore.com>
4862 * einfo.ads (Component_Bit_Offset): Fix documentation.
4863 * sem_ch13.adb (Check_Record_Representation_Clause): Skip check
4864 on record holes for components with unknown compile-time offsets.

4868 * ali.ads, ali.adb (Static_Elaboration_Model_Used): Remove unused flag.
4869 * g-locfil.ads: Minor comment fix.
4871 2017-01-13 Bob Duff <duff@adacore.com>
4873 * binde.adb (Elab_New): New elaboration order algorithm
4874 that is expected to cause fewer ABE issues. This is a work in
4875 progress. The new algorithm is currently disabled, and can be
4876 enable by the -dp switch, or by modifying the Do_Old and Do_New
4877 etc. flags and rebuilding. Experimental code is included to
4878 compare the results of the old and new algorithms.
4879 * binde.ads: Use GNAT.Dynamic_Tables instead of Table, so we
4880 can have multiple of these tables, so the old and new algorithms
4882 * bindgen.ads (Gen_Output_File): Pass Elab_Order as an 'in'
4883 parameter of type array. This avoids the global variable, and
4884 allows bounds checking (which is normally defeated by the tables
4885 packages). It also ensures that the Elab_Order is read-only
4887 * bindgen.adb: Pass Elab_Order as an 'in' parameter to all
4888 subprograms that need it, as above.
4889 * debug.adb: Document new -dp switch. Modify doc of old -do
4891 * gnatbind.adb (Gnatbind): Make use of new interfaces to Binde
4892 and Bindgen. Move writing of closure (-R and -Ra switches)
4893 to Binde; that's more convenient.
4895 2017-01-13 Ed Schonberg <schonberg@adacore.com>
4897 * sem_ch6.adb (Analyze_Expression_Function): If the expression
4898 function is a completion, all entities referenced in the
4899 expression are frozen. As a consequence, a reference to an
4900 uncompleted private type from an enclosing scope is illegal.
4902 2017-01-13 Javier Miranda <miranda@adacore.com>
4904 * sem_ch6.adb (Freeze_Expr_Types): New subprogram.
4905 (Analyze_Subprogram_Body_Helper): At the occurrence of an
4906 expression function declaration that is a completion, its
4907 expression causes freezing (AI12-0103).
4909 2017-01-13 Vadim Godunko <godunko@adacore.com>
4911 * a-coinho-shared.adb: Fix memory leaks in Constant_Reference and
4912 Reference functions of Ada.Containers.Indefinite_Holders.
4914 2017-01-13 Bob Duff <duff@adacore.com>
4916 * s-os_lib.ads: Minor comment fixes.
4918 2017-01-13 Hristian Kirtchev <kirtchev@adacore.com>
4920 * exp_ch3.adb (Default_Initialize_Object): Do not default
4921 initialize an object when it is of a task type and restriction
4922 No_Tasking is in effect because the initialization is obsolete.
4923 * exp_ch9.adb (Build_Master_Entity): Do not generate a master when
4924 restriction No_Tasking is in effect.
4925 (Build_Master_Renaming): Do not rename a master when restriction
4926 No_Tasking is in effect.
4928 2017-01-13 Ed Schonberg <schonberg@adacore.com>
4930 * sem_aggr.adb (Resolve_Array_Aggregate): The code that verifies
4931 the legality of An others clause applies as well to a choice in
4932 an Iterated_component_ association.
4933 (Resolve_Iterated_Component_Association): An others choice
4935 * exp_aggr.adb (Aggr_Assignment_OK_For_Backend): An
4936 Iterated_Component_Association is not static.

4944 Analyze_Subprogram_Instantiation): Mark the Ghost mode as set

4957 2017-01-13 Ed Schonberg <schonberg@adacore.com>
4959 * sem_util.ads, sem_util.adb (Choice_List): Move function here
4960 from sem_aggr.adb, for use elsewhere.
4961 * sem_ch3.adb (Analyze_Object_Declaration): Use Choice_List.
4962 * sem_aggr.adb (Resolve_Array_Aggregate): Remove
4963 Iterated_Component_Present.
4964 * exp_aggr.adb: Use Choice_List throughout, to handle
4965 Iterated_Component_Associations.
4966 (Gen_Loop): Generate proper loop for an
4967 Iterated_Component_Association: loop variable has the identifier
4968 of the original association. Generate a loop even for a single
4969 component choice, in order to make loop parameter visible in
4971 (Flatten): An Iterated_Component_Association is not static.
4973 2017-01-13 Yannick Moy <moy@adacore.com>
4975 * exp_ch4.adb (Expand_N_Op_Expon): Ensure that the value of
4976 float exponentiation for statically known small negative values
4977 is the reciprocal of the exponentiation for the opposite value
4979 * s-exnllf.adb (Exn_Float, Exn_Long_Float, Exn_Long_Long_Float):
4980 Ensure that the value of float exponentiation for negative values
4981 is the reciprocal of the exponentiation for the opposite value
4983 * inline.adb (Expand_Inlined_Call): Fix the count
4984 for the number of generated gotos.
4986 2017-01-13 Yannick Moy <moy@adacore.com>

4990 expression in delay statement as OK for volatile context.
4992 2017-01-13 Ed Schonberg <schonberg@adacore.com>
4994 * sem_aggr.adb (Resolve_Array_Aggregate): In normal compilation
4995 mode a choice that is a subtype with a static predicate is
4996 replaced by the values it covers. This transformation must not
4997 be performed in ASIS mode, to preserve the source for analysis.
4999 2017-01-13 Justin Squirek <squirek@adacore.com>
5001 * nlists.ads: Correct minor typo.

5013 procedure, subsidiary of Resolve_Array_Aggregate, to analyze
5014 and resolve the discrete choices and the expression of the
5016 * sinfo.adb, sinfo.ads: In analogy with N_Component_Association,
5017 Loop_Actions and Box_Present are attributes of
5018 N_Iterated_Component_Association nodes. Box_Present is always
5020 * sprint.adb (Sprint_Node): An Iterated_Component_Association
5021 has a Discrete_Choices list, as specified in the RM. A
5022 Component_Association for aggregate uses instead a Choices list.
5023 We have to live with this small inconsistency because the new
5024 construct also has a defining identifier, and there is no way
5025 to merge the two node structures.
5027 2017-01-13 Yannick Moy <moy@adacore.com>
5029 * inline.adb (Remove_Aspects_And_Pragmas): Add Unused to the
5030 list of pragmas to remove. Remove pragmas from the list of

5034 2017-01-13 Ed Schonberg <schonberg@adacore.com>
5036 * sem_ch3.adb (Resolve_Aspects): New procedure, subsidiary of
5037 Analyze_Declarations, to analyze and resolve the expressions of
5038 aspect specifications in the current declarative list, so that
5039 the expressions have proper entity and type info. This is needed
5040 for ASIS when there is no subsequent expansion to generate this
5041 semantic information.
5042 * sem_ch13.adb (Check_Aspect_At_End_Of_Declarations): Use Etype of
5043 original expression, to suppress cascaded errors when expression
5044 has been constant-folded.
5045 (Resolve_Aspect_Expressions, Resolve_Name): Preserve entities in
5046 ASIS mode, because there is no subsequent expansion to decorate
5049 2017-01-13 Yannick Moy <moy@adacore.com>
5051 * inline.adb, inline.ads (Call_Can_Be_Inlined_In_GNATprove_Mode):
5052 New function to detect when a call may be inlined or not in
5054 (Expand_Inlined_Call): Ensure that a temporary
5055 is always created in the cases where a type conversion may be
5056 needed on an input parameter in GNATprove mode, so that GNATprove
5057 sees the check to perform.
5058 * sem_res.adb (Resolve_Call): In GNATprove mode, skip inlining
5059 when not applicable due to actual requiring type conversion
5060 with possible check but no temporary value can be copied for
5061 GNATprove to see the check.
