1103 (To_Domain): Add postcondition regarding sorting of result.
1104 (To_Range): Fix postcondition that should compare Length instead

1396 * exp_ch4.adb (Expand_N_Indexed_Component): The two improvements
1399 2021-10-01 Bob Duff <duff@adacore.com>
1401 * exp_ch6.adb (Expand_Call_Helper): Do not call
1402 Check_Subprogram_Variant if the subprogram is an ignored ghost
1403 entity. Otherwise the compiler crashes (in debug builds) or

1417 Apply_Subscript_Validity_Checks so that callers can indicate
1418 that no check is needed for certain dimensions.
1419 * checks.adb (Generate_Index_Checks): Implement new
1420 Checks_Generated parameter.
1421 (Apply_Subscript_Validity_Checks): Implement new No_Check_Needed
1423 * exp_ch4.adb (Expand_N_Indexed_Component): Call

1425 includes declaring two new local functions,
1426 (Is_Renamed_Variable_Name,
1427 Type_Requires_Subscript_Validity_Checks_For_Reads): To help in
1428 deciding whether to call Apply_Subscript_Validity_Checks.

1438 2021-10-01 Bob Duff <duff@adacore.com>
1440 * table.ads (Table_Type): Remove "aliased"; no longer needed by
1441 Atree. Besides it contradicted the comment a few lines above,
1442 "-- Note: We do not make the table components aliased...".
1443 * types.ads: Move type Slot to Atree.
1444 * atree.ads: Move type Slot fromt Types to here. Move type
1445 Node_Header from Seinfo to here.
1446 * atree.adb: Avoid the need for aliased components of the Slots
1447 table. Instead of 'Access, use a getter and setter. Misc
1449 (Print_Statistics): Print statistics about node and entity kind
1450 frequencies. Give 3 digit fractions instead of percentages.
1451 * (Get_Original_Node_Count, Set_Original_Node_Count): Statistics
1452 for calls to Original_Node and Set_Original_Node.
1453 (Original_Node, Set_Original_Node): Gather statistics by calling
1455 (Print_Field_Statistics): Print Original_Node statistics.
1456 (Update_Kind_Statistics): Remove, and put all statistics
1457 gathering under "if Atree_Statistics_Enabled", which is a flag
1458 generated in Seinfo by Gen_IL.
1459 * gen_il-gen.adb (Compute_Field_Offsets): Choose offsets of
1460 Nkind, Ekind, and Homonym first. This causes a slight efficiency
1461 improvement. Misc cleanups. Do not generate Node_Header; it is
1462 now hand-written in Atree. When choosing the order in which to
1463 assign offsets, weight by the frequency of the node type, so the
1464 more common nodes get their field offsets assigned earlier. Add
1466 (Compute_Type_Sizes): Remove this and related things.
1467 There was a comment: "At some point we can instrument Atree to
1468 print out accurate size statistics, and remove this code." We
1469 have Atree statistics, so we now remove this code.
1470 (Put_Seinfo): Generate Atree_Statistics_Enabled, which is equal
1471 to Statistics_Enabled. This allows Atree to say "if
1472 Atree_Statistics_Enabled then <gather statistics>" for
1473 efficiency. When Atree_Statistics_Enabled is False, the "if ..."
1474 will be optimized away.
1475 * gen_il-internals.ads (Type_Frequency): New table of kind
1477 * gen_il-internals.adb: Minor comment improvement.
1478 * gen_il-fields.ads: Remove unused subtypes. Suppress style
1479 checks in the Type_Frequency table. If we regenerate this
1480 table (see -gnatd.A) we don't want to have to fiddle with
1482 * impunit.adb: Minor.
1483 * sinfo-utils.adb: Minor.
1484 * debug.adb: Minor comment improvement.

1714 number, as in "GNAT Lib v22.20210809".
1716 2021-10-01 Steve Baird <baird@adacore.com>
1718 * sem_res.adb (Resolve): Two separate fixes. In the case where
1719 Find_Aspect for a literal aspect returns the aspect for a
1720 different (ancestor) type, call Corresponding_Primitive_Op to
1721 get the right callee. In the case where a downward tagged type
1722 conversion appears to be needed, generate a null extension
1723 aggregate instead, as per Ada RM 3.4(27).
1724 * sem_util.ads, sem_util.adb: Add new Corresponding_Primitive_Op
1725 function. It maps a primitive op of a tagged type and a
1726 descendant type of that tagged type to the corresponding
1727 primitive op of the descendant type. The body of this function
1728 was written by Javier Miranda.
1730 2021-10-01 Bob Duff <duff@adacore.com>

1780 version mismatch, if distinct integer values can be extracted
1781 from the two version strings then include those values in the
1782 generated error message.
1784 2021-10-01 Steve Baird <baird@adacore.com>
1786 * sem_elab.adb (Is_Safe_Call): Return True in the case of a

1833 for internally generated attributes; otherwise, compute them
1836 2021-09-23 Javier Miranda <miranda@adacore.com>
1838 * sem_ch3.adb (Build_Access_Subprogram_Wrapper): Decorate the
1839 wrapper with attribute Is_Wrapper, and move its declaration to
1840 the freezing actions of its type declaration; done to facilitate
1841 identifying it at later stages to avoid handling it as a
1842 primitive operation of a tagged type; otherwise it may be
1843 handled as a dispatching operation and erroneously registered in
1845 (Make_Index): Add missing decoration of field Parent.
1846 * sem_disp.adb (Check_Dispatching_Operation): Complete
1847 decoration of late-overriding dispatching primitives.
1848 (Is_Access_To_Subprogram_Wrapper): New subprogram.
1849 (Inherited_Subprograms): Prevent cascaded errors; adding missing
1850 support for private types.
1851 * sem_type.adb (Add_One_Interp): Add missing support for the
1852 first interpretation of a primitive of an inmediate ancestor
1854 * sem_util.adb (Check_Result_And_Post_State_In_Pragma): Do not
1855 report missing reference in postcondition placed in internally

1863 component associations.
1864 * exp_aggr.adb (Expand_Array_Aggregate,
1865 Two_Pass_Aggregate_Expansion): implement two-pass algorithm and
1866 replace original aggregate with resulting temporary, to ensure
1867 that a proper length check is performed if context is
1868 constrained. Use attributes Pos and Val to handle index types of
1871 2021-09-23 Bob Duff <duff@adacore.com>
1873 * gen_il-gen.adb: Set the number of concrete nodes that have the
1874 Homonym field to a higher number than any other field. This
1875 isn't true, but it forces Homonym's offset to be chosen first,
1876 so it will be at offset zero and hence slot zero.
1878 2021-09-23 Richard Kenner <kenner@adacore.com>
1880 * atree.adb (Relocate_Node): If relocating a subprgram call and

1887 Initializes contract.
1889 2021-09-23 Bob Duff <duff@adacore.com>
1891 * gen_il-gen.adb: Generate getters and setters with much of the
1892 code inlined. Generate code for storing a few fields in the node
1893 header, to avoid the extra level of indirection for those
1894 fields. We generate the header type, so we don't have to
1895 duplicate hand-written Ada and C code to depend on the number of
1896 header fields. Declare constants for slot size. Use short names
1897 because these are used all over. Remove
1898 Put_Low_Level_Accessor_Instantiations, Put_Low_Level_C_Getter,
1899 which are no longer needed. Rename
1900 Put_High_Level_C_Getter-->Put_C_Getter.
1901 * atree.ads, atree.adb: Take into account the header slots.
1902 Take into account the single Node_Or_Entity_Field type. Remove
1903 "pragma Assertion_Policy (Ignore);", because the routines in
1904 this package are no longer efficiency critical.
1905 * atree.h: Remove low-level getters, which are no longer used by
1906 sinfo.h and einfo.h.
1907 * einfo-utils.adb: Avoid crash in Known_Alignment.
1908 * live.adb, sem_eval.adb: Remove code that prevents Node_Id from
1909 having a predicate. We don't actually add a predicate to
1910 Node_Id, but we want to be able to for temporary debugging.
1911 * sinfo-utils.adb: Remove code that prevents Node_Id from having
1912 a predicate. Take into account the single Node_Or_Entity_Field
1914 * sinfo-utils.ads: Minor.
1915 * table.ads (Table_Type): Make the components aliased, because
1916 low-level setters in Atree need to take 'Access.
1917 * treepr.adb: Take into account the single Node_Or_Entity_Field
1918 type. Make some code more robust, so we can print out
1920 * types.ads: Move types here for visibility purposes.
1921 * gcc-interface/gigi.h, gcc-interface/trans.c: Take into account
1922 the Node_Header change in the GNAT front end.
1923 * gcc-interface/cuintp.c, gcc-interface/targtyps.c: Add because
1924 gigi.h now refers to type Node_Header, which is in sinfo.h.
1926 2021-09-23 Yannick Moy <moy@adacore.com>
1928 * libgnat/a-strfix.adb (Delete, Insert, Overwrite,

2393 a value is provided via the -d switch, and generate a call to
2394 __gnat_initialize_stack_limit if stack checking using stack

2399 * sem_ch13.adb (Stream_Size): Print message about allowed stream
2400 sizes even if other error were already found. This avoids
2401 falling into the 'else', which prints "Stream_Size cannot be
2402 given for...", which is misleading -- the Size COULD be given if
2405 2021-09-21 Daniel Mercier <mercier@adacore.com>
2407 * exp_util.adb (Build_Temporary): In case of an external DISCR
2408 symbol, set the related expression for CodePeer so that a more

2437 the formal parameter to Valid_Uint. Remove code that preserved
2438 the previous behavior, and replace it with an assertion. The
2439 previous behavior is no longer needed given the recent change to
2441 (No, Present): Add comment.

2451 (Ubool, Opt_Ubool): New "boolean" subtypes.
2452 (UI_Is_In_Int_Range): The parameter should probably be
2453 Valid_Uint, but we don't change that for now, because it causes

2456 Static_Boolean): Use Opt_Ubool subtype. Document the fact that
2457 Is_True (No_Uint) = True. Implement Is_False in terms of
2458 Is_True. We considered changing Static_Boolean to return Uint_1
2459 in case of error, but that doesn't fit in well with
2461 (Has_Compatible_Alignment_Internal): Deal with cases where Offs
2462 is No_Uint. Change one "and" to "and then" to ensure we don't
2463 pass No_Uint to ">", which would violate the new assertions.
2464 * exp_util.adb, freeze.adb, sem_ch13.adb: Avoid violating new
2465 assertions in Uintp.

2491 * Makefile.rtl (aarch64-rtems*): Add GNATRTL_128BIT_PAIRS to

2498 test for an E_Operator as part of criteria for setting
2499 Abstract_Op on interpretations involving predefined operators.

2503 * exp_ch6.adb (Expand_Simple_Function_Return): For explicit

2505 the tag of the result is that of the result type.
2507 2021-09-21 Bob Duff <duff@adacore.com>
2509 * einfo-utils.adb: Add support (currently disabled) for using
2510 "initial zero" instead of "Uint_0" to represent "unknown". Call
2511 Known_ functions, instead of evilly duplicating their code
2513 * fe.h (No_Uint_To_0): New function to convert No_Uint to
2514 Uint_0, in order to preserve existing behavior.
2515 (Copy_Esize, Copy_RM_Size): New imports from Einfo.Utils.
2516 * cstand.adb: Set size fields of Standard_Debug_Renaming_Type
2517 and Standard_Exception_Type.
2518 * checks.adb, exp_attr.adb, exp_ch3.adb, exp_ch5.adb,

2521 sem_ch13.adb, sem_ch13.ads, sem_ch3.adb, sem_ch7.adb,
2522 sem_util.adb: Protect calls with Known_..., use Copy_... Remove
2523 assumption that Uint_0 represents "unknown".
2524 * types.ads (Nonzero_Int): New subtype.
2525 * gcc-interface/decl.c, gcc-interface/trans.c: Protect calls
2526 with Known_... and use Copy_... as appropriate, to avoid

2532 * sem_ch13.adb (Analyze_Aspect_Specifications): Add a new nested
2533 function, Directly_Specified, and then use it in the
2534 implementation of the required check.
2536 2021-09-21 Steve Baird <baird@adacore.com>
2538 * libgnat/a-costso.ads, libgnat/a-costso.adb: A new library
2539 unit, Ada.Containers.Stable_Sorting, which exports a pair of
2540 generics (one within the other) which are instantiated by each
2541 of the 5 doubly-linked list container generics to implement
2542 their respective Sort procedures. We use a pair of generics,
2543 rather than a single generic, in order to further reduce code
2544 duplication. The outer generic takes a formal private Node_Ref
2545 type representing a reference to a linked list element. For some
2546 instances, the corresponding actual parameter will be an access
2547 type; for others, it will be the index type for an array.
2548 * Makefile.rtl: Include new Ada.Containers.Stable_Sorting unit.

2790 * sem_ch7.adb (Analyze_Package_Specification): On call to
2791 Has_Preelaborable_Initialization, pass True for new formal

2794 having preelaborable initialization when the subcomponents are
2796 * sem_ch13.adb (Analyze_Aspects_At_Freeze_Point): Add test for
2797 P_I to prevent calling Make_Pragma_From_Boolean_Aspect, since
2798 this aspect is handled specially and the

2800 the aspect by other means.
2801 (Analyze_Aspect_Specifications.Analyze_One_Aspect): Add test for
2802 Aspect_Preelaborable_Initialization for allowing the aspect to
2803 be specified on formal type declarations.

2825 within Is_Conjunction_Of_Formal_Preelab_Init_Attributes that
2826 determines whether a node is a P_I attribute applied to a

2829 so it can be called by Analyze_Attribute.
2830 * snames.ads-tmpl: Add note near the start of spec giving
2831 details about what needs to be done when adding a name that
2832 corresponds to both an attribute and a pragma. Delete existing
2833 occurrence of Name_Preelaborable_Initialization, and add a note
2834 comment in the list of Name_* constants at that place,
2835 indicating that it's included in type Pragma_Id, etc., echoing
2836 other such comments for names that are both an attribute and a
2837 pragma. Insert Name_Preelaborable_Initialization in the
2838 alphabetized set of Name_* constants corresponding to
2839 attributes (between First_Attribute_Name and
2840 Last_Attribute_Name).

2842 Attribute_Preelaborable_Initialization.
2843 (type Pragma_Id): Move Pragma_Preelaborable_Initialization from
2844 its current position to the end of the type, in the special set
2845 of pragma literals that have corresponding atttributes. Add to
2846 accompanying comment, indicating that functions Get_Pragma_Id
2847 and Is_Pragma_Name need to be updated when adding a pragma
2848 literal to the special set.
2849 * snames.adb-tmpl (Get_Pragma_Id): Add case alternative for
2850 Pragma_Preelaborable_Initialization.

3060 2021-07-12 Eric Botcazou <ebotcazou@adacore.com>
3062 * gcc-interface/decl.c (gnat_to_gnu_entity) <E_Array_Type>: Use a
3063 fixed lower bound if the index subtype is marked so, as well as a
3064 more efficient formula for the upper bound if the array cannot be
3066 (flb_cannot_be_superflat): New predicate.
3067 (cannot_be_superflat): Rename into...
3068 (range_cannot_be_superfla): ...this. Minor tweak.
3070 2021-07-12 Bob Duff <duff@adacore.com>
3072 * uintp.ads, types.h: New subtypes of Uint: Valid_Uint, Unat,
3073 Upos, Nonzero_Uint with predicates. These correspond to new
3074 field types in Gen_IL.
3075 * gen_il-types.ads (Valid_Uint, Unat, Upos, Nonzero_Uint): New
3077 * einfo-utils.ads, einfo-utils.adb, fe.h (Known_Alignment,
3078 Init_Alignment): Use the initial zero value to represent
3079 "unknown". This will ensure that if Alignment is called before
3080 Set_Alignment, the compiler will blow up (if assertions are
3082 * atree.ads, atree.adb, atree.h, gen_il-gen.adb
3083 (Get_Valid_32_Bit_Field): New generic low-level getter for
3085 (Copy_Alignment): New procedure to copy Alignment field even
3087 (Init_Object_Size_Align, Init_Size_Align): Do not bypass the
3089 * exp_pakd.adb, freeze.adb, layout.adb, repinfo.adb,
3090 sem_util.adb: Protect calls to Alignment with Known_Alignment.
3091 Use Copy_Alignment when it might be unknown.
3092 * gen_il-gen-gen_entities.adb (Alignment,
3093 String_Literal_Length): Use type Unat instead of Uint, to ensure
3094 that the field is always Set_ before we get it, and that it is
3095 set to a nonnegative value.
3096 (Enumeration_Pos): Unat.
3097 (Enumeration_Rep): Valid_Uint. Can be negative, but must be
3098 valid before fetching.
3099 (Discriminant_Number): Upos.
3100 (Renaming_Map): Remove.
3101 * gen_il-gen-gen_nodes.adb (Char_Literal_Value, Reason): Unat.

3110 (Offset_Value): Protect calls to Alignment with Known_Alignment.
3111 * sem_prag.adb (Set_Atomic_VFA): Do not use Uint_0 to mean
3112 "unknown"; call Init_Alignment instead.

3114 * treepr.adb: Deal with printing of new field types.
3115 * einfo.ads, gen_il-fields.ads (Renaming_Map): Remove.
3116 * gcc-interface/decl.c (gnat_to_gnu_entity): Use Known_Alignment
3117 before calling Alignment. This preserve some probably buggy
3118 behavior: if the alignment is not set, it previously defaulted
3119 to Uint_0; we now make that explicit. Use Copy_Alignment,
3120 because "Set_Alignment (Y, Alignment (X));" no longer works when
3121 the Alignment of X has not yet been set.
3122 * gcc-interface/trans.c (process_freeze_entity): Use
3125 2021-07-12 Eric Botcazou <ebotcazou@adacore.com>

3152 Check_One_Attr, with a parameter for the attribute_designator we
3153 are looking for, and one for the attribute_designator of the

3155 Value_Size, call it twice, once for each.

3179 2021-07-09 Bob Duff <duff@adacore.com>
3181 * exp_put_image.adb (Make_Component_Attributes): Use
3182 Implementation_Base_Type to get the parent type. Otherwise,
3183 Parent_Type_Decl is actually an internally generated subtype
3184 declaration, so we blow up on
3185 Type_Definition (Parent_Type_Decl).
3187 2021-07-09 Dmitriy Anisimkov <anisimko@adacore.com>
3189 * gsocket.h: Include net/if.h to get IF_NAMESIZE constant.

3202 obtaining its entity.

3207 "releases") plus comment reformatting.
3208 * libgnat/s-os_lib.ads: In a comment, fix typo ("indended" =>
3209 "intended"), add a hyphen and semicolon, plus reformatting. In

3228 Done variable and modify how Next_Part is computed so that it is
3229 always correct (as opposed to being incorrect when Done is
3230 True). This includes changes in Update_Result (a local
3231 procedure). Add new local procedure
3232 Update_Result_For_Box_Component and call it not just for box
3233 components but also for "missing" components (components
3234 associated with an inactive variant).
3235 (Check_Choices.Check_Composite_Case_Selector.Check_Component_Subtype):
3236 Instead of disallowing all discriminated component types, allow
3237 those that are unconstrained or statically constrained. Check
3238 discriminant subtypes along with other component subtypes.
3239 * doc/gnat_rm/implementation_defined_pragmas.rst: Update
3240 documentation to reflect current implementation status.

3527 erroneous and return.
3529 2021-07-08 Ghjuvan Lacambre <lacambre@adacore.com>
3531 * exp_prag.adb (Expand_Pragma_Inspection_Point): Fix error
3534 2021-07-08 Yannick Moy <moy@adacore.com>
3536 * layout.adb (Layout_Type): Do not call Number_Dimensions if the
3537 type does not have First_Index set.
3539 2021-07-08 Ghjuvan Lacambre <lacambre@adacore.com>
3541 * exp_prag.adb (Expand_Pragma_Inspection_Point): After expansion
3542 of the Inspection_Point pragma, check if referenced entities
3543 that have a freeze node are already frozen. If they aren't, emit
3544 a warning and turn the pragma into a no-op.
3546 2021-07-08 Yannick Moy <moy@adacore.com>
3548 * layout.adb (Layout_Type): Add guard before calling Expr_Value.
3550 2021-07-08 Yannick Moy <moy@adacore.com>
3552 * layout.adb (Layout_Type): Special case when RM_Size and Esize
3553 can be computed for packed arrays.
3555 2021-07-08 Steve Baird <baird@adacore.com>
3557 * rtsfind.ads, rtsfind.adb: Add support for finding the packages
3558 System.Atomic_Operations and
3559 System.Atomic_Operations.Test_And_Set and the declarations
3560 within that latter package of the type Test_And_Set_Flag and the
3561 function Atomic_Test_And_Set.
3562 * exp_ch11.adb (Expand_N_Exception_Declaration): If an exception
3563 is declared other than at library level, then we need to call
3564 Register_Exception the first time (and only the first time) the
3565 declaration is elaborated. In order to decide whether to
3566 perform this call for a given elaboration of the declaration, we
3567 used to unconditionally use a (library-level) Boolean variable.
3568 Now we instead use a variable of type
3569 System.Atomic_Operations.Test_And_Set.Test_And_Set_Flag unless
3570 either that type is unavailable or a No_Tasking restriction is
3571 in effect (in which case we use a Boolean variable as before).
3573 2021-07-08 Arnaud Charlet <charlet@adacore.com>
3575 * gcc-interface/system.ads: Add No_Tasking restriction.
3577 2021-07-08 Ed Schonberg <schonberg@adacore.com>
3579 * libgnat/a-cohama.ads: Introduce an equality operator over
3581 * libgnat/a-cohase.ads: Ditto.
3582 * libgnat/a-cohama.adb: Add body for "=" over cursors.
3583 (Insert): Do not set the Position component of the cursor that
3584 denotes the inserted element.
3585 * libgnat/a-cohase.adb: Ditto.
3587 2021-07-08 Arnaud Charlet <charlet@adacore.com>
3589 * libgnat/a-cbdlli.adb, libgnat/a-cbhama.adb,
3590 libgnat/a-cbhase.adb, libgnat/a-cbmutr.adb,

3592 libgnat/a-cobove.adb, libgnat/a-textio.adb,
3593 libgnat/a-witeio.adb, libgnat/a-ztexio.adb: Make code compatible
3594 with No_Dynamic_Accessibility_Checks restriction.
3596 2021-07-08 Arnaud Charlet <charlet@adacore.com>
3598 * debug.adb, sem_util.adb: Revert meaning of -gnatd_b.
3599 * sem_res.adb: Minor reformatting.
3601 2021-07-08 Arnaud Charlet <charlet@adacore.com>
3603 * make.adb, osint.adb: Make code compatible with
3604 No_Dynamic_Accessibility_Checks restriction.
3606 2021-07-08 Piotr Trojanek <trojanek@adacore.com>
3608 * lib-writ.adb (Ensure_System_Dependency): Replace search in
3609 Lib.Units with a search in Lib.Unit_Names.
3611 2021-07-08 Piotr Trojanek <trojanek@adacore.com>
3613 * sinput-l.adb (Load_File): Simplify foreword manipulation with
3614 concatenation; similar for filename with preprocessed output.
3616 2021-07-07 Dmitriy Anisimkov <anisimko@adacore.com>
3618 * s-oscons-tmplt.c (MSG_WAITALL): Remove wrong #ifdef
3621 2021-07-07 Gary Dismukes <dismukes@adacore.com>
3623 * einfo-utils.adb (Primitive_Operations): Default to returning
3624 Direct_Primitive_Operations in the case of concurrent types
3625 (when Corresponding_Record_Type not present).
3626 * sem_ch9.adb (Analyze_Protected_Type_Declaration): Initialize
3627 Direct_Primitive_Operations to an empty element list.
3628 (Analyze_Task_Type_Declaration): Initialize
3629 Direct_Primitive_Operations to an empty element list.
3631 2021-07-07 Piotr Trojanek <trojanek@adacore.com>
3633 * sem_eval.adb (Set_Checking_Potentially_Static_Expression):
3636 2021-07-07 Arnaud Charlet <charlet@adacore.com>
3638 * sem_ch12.adb (Analyze_Subprogram_Instantiation): Mark Anon_Id
3639 intrinsic before calling Analyze_Instance_And_Renamings because
3640 this flag may be propagated to other nodes.
3642 2021-07-07 Dmitriy Anisimkov <anisimko@adacore.com>
3644 * s-oscons-tmplt.c (TCP_KEEPCNT TCP_KEEPIDLE, TCP_KEEPINTVL):
3645 Hardcode on Windows if undefined.
3647 2021-07-07 Bob Duff <duff@adacore.com>
3649 * checks.adb (Install_Primitive_Elaboration_Check): Do not
3650 generate elaboration checks for primitives if pragma Pure or
3651 Preelaborate is present. Misc comment fixes, including
3652 referring to the correct kind of check (elaboration, not
3654 * checks.ads, restrict.adb, sem_cat.ads, sinfo.ads: Minor
3655 reformatting and comment fixes.
3657 2021-07-07 Piotr Trojanek <trojanek@adacore.com>
3659 * sem_prag.adb (Analyze_Pragma): Simplify processing of pragma
3662 2021-07-07 Arnaud Charlet <charlet@adacore.com>
3664 * libgnat/g-debpoo.adb (Code_Address_For_Allocate_End): Default
3667 2021-07-07 Arnaud Charlet <charlet@adacore.com>
3669 * libgnat/s-atocou.ads, libgnat/s-atocou__builtin.adb: Code
3672 2021-07-07 Gary Dismukes <dismukes@adacore.com>
3674 * freeze.adb (Check_Inherited_Conditions): Setting of Ekind,
3675 LSP_Subprogram, and Is_Wrapper needs to happen for null
3676 procedures as well as other wrapper cases, so the code is moved
3677 from the else part in front of the if statement. (Fixes a
3678 latent bug encountered while working on this set of changes.)
3679 * sem_attr.adb (Resolve_Attribute): Report an error for the case
3680 of an Access attribute applied to a primitive of an abstract
3681 type when the primitive has any nonstatic Pre'Class or
3682 Post'Class expressions.
3683 * sem_ch8.adb (Analyze_Subprogram_Renaming): Report an error for
3684 the case of a actual subprogram associated with a nonabstract
3685 formal subprogram when the actual is a primitive of an abstract
3686 type and the primitive has any nonstatic Pre'Class or Post'Class
3688 * sem_disp.adb (Check_Dispatching_Context): Remove special
3689 testing for null procedures, and replace it with a relaxed test
3690 that avoids getting an error about illegal calls to abstract
3691 subprograms in cases where RM 6.1.1(7/5) applies in
3692 Pre/Post'Class aspects. Also, remove special test for
3693 Postcondition, which seems to be unnecessary, update associated
3694 comments, and fix a typo in one comment.
3695 (Check_Dispatching_Call): Remove an unneeded return statement,
3696 and report an error for the case of a nondispatching call to a
3697 nonabstract subprogram of an abstract type where the subprogram
3698 has nonstatic Pre/Post'Class aspects.
3700 (Is_Prim_Of_Abst_Type_With_Nonstatic_CW_Pre_Post): New function.
3701 (In_Pre_Post_Condition): Add a flag formal Class_Wide_Only,
3702 defaulted to False, for indicating whether the function should
3703 only test for the node being within class-wide pre- and
3706 (Is_Prim_Of_Abst_Type_With_Nonstatic_CW_Pre_Post): New function
3707 to determine whether a subprogram is a primitive of an abstract
3708 type where the primitive has class-wide Pre/Post'Class aspects
3709 specified with nonstatic expressions.
3710 (In_Pre_Post_Condition): Extend testing to account for the new
3711 formal Class_Wide_Only.
3713 2021-07-07 Piotr Trojanek <trojanek@adacore.com>
3715 * sem_ch12.adb (Check_Shared_Variable_Control_Aspects): Errors
3716 emitted via Check_Volatility_Compatibility are now emitted at
3717 Actual, just like other errors emitted by
3718 Check_Shared_Variable_Control_Aspects.
3720 2021-07-07 Piotr Trojanek <trojanek@adacore.com>
3722 * uname.adb (Get_Unit_Name): Simplify with a bounded string
3723 buffer; also, this addresses a ??? comment about the max length
3726 2021-07-07 Piotr Trojanek <trojanek@adacore.com>
3728 * uname.adb (Get_Body_Name, Get_Parent_Body_Name,
3729 Get_Parent_Spec_Name, Get_Spec_Name, Is_Child_Name,
3730 Is_Body_Name, Is_Spec_Name, Name_To_Unit_Name): Use a local
3731 instead of the global buffer.
3733 2021-07-07 Bob Duff <duff@adacore.com>
3735 * sem_ch13.adb (Analyze_Attribute_Definition_Clause): Combine
3736 processing of Size and Value_Size clauses. Ensure that
3737 Value_Size is treated the same as Size, in the cases where both
3738 are allowed (i.e. the prefix denotes a first subtype). Misc
3740 * einfo-utils.adb (Init_Size): Add assertions.
3741 (Size_Clause): Return a Value_Size clause if present, instead of
3742 just looking for a Size clause.
3743 * einfo.ads (Has_Size_Clause, Size_Clause): Change documentation
3744 to include Value_Size.
3745 * sem_ch13.ads, layout.ads, layout.adb: Comment modifications.
3747 2021-07-07 Steve Baird <baird@adacore.com>
3749 * exp_dist.adb (Add_RACW_Primitive_Declarations_And_Bodies): Add
3750 TSS_Put_Image to list of predefined primitives that need special
3752 (Build_General_Calling_Stubs, Build_Subprogram_Receiving_Stubs):
3753 Remove previous hack for dealing with TSS_Put_Image procedures.
3755 2021-07-07 Dmitriy Anisimkov <anisimko@adacore.com>
3757 * libgnat/g-socket.adb (Get_Socket_Option): Add 500ms only when
3758 Minus_500ms_Windows_Timeout is True.
3759 (Set_Socket_Option): Use "* 1000" instead of "/ 0.001" to
3760 convert to milliseconds.
3762 2021-07-07 Bob Duff <duff@adacore.com>
3764 * tbuild.adb (Unchecked_Convert_To): Set the Parent of the new
3765 node to the Parent of the old node.
3766 * tbuild.ads (Unchecked_Convert_To): Document differences
3767 between Convert_To and Unchecked_Convert_To. The previous
3768 documentation claimed they are identical except for the
3769 uncheckedness of the conversion.
3771 2021-07-07 Yannick Moy <moy@adacore.com>
3773 * checks.adb (Apply_Scalar_Range_Check): Remove special case for
3775 * sem_res.adb (Resolve_Arithmetic_Op): Same.
3776 * sem_util.adb (Apply_Compile_Time_Constraint_Error): Same.
3778 2021-07-07 Piotr Trojanek <trojanek@adacore.com>
3780 * sem_ch6.adb (Check_For_Primitive_Subprogram): Move
3781 declarations of local variables after nested subprogram bodies.
3783 2021-07-07 Piotr Trojanek <trojanek@adacore.com>
3785 * exp_disp.adb (CPP_Num_Prims): Reuse List_Length.
3787 2021-07-07 Piotr Trojanek <trojanek@adacore.com>
3789 * exp_ch3.adb, exp_ch6.adb, sem_ch6.adb: Replace Ekind
3790 membership test in Private_Kind with a call to Is_Private_Type.
3792 2021-07-07 Bob Duff <duff@adacore.com>
3794 * gen_il-gen-gen_entities.adb: Remove Linker_Section_Pragma
3795 field from Record_Field_Kind. Minor comment improvement.
3797 2021-07-07 Yannick Moy <moy@adacore.com>
3799 * libgnat/a-ngelfu.ads (Cot): Fix precondition.
3801 2021-07-07 Piotr Trojanek <trojanek@adacore.com>
3803 * par.adb (Par): A local Name variable is now a renaming of a
3806 2021-07-07 Piotr Trojanek <trojanek@adacore.com>
3808 * gnat1drv.adb (Gnat1drv): Remove flagging of main unit and its
3809 corresponding spec as requiring code generation; now the flags
3810 are set much earlier.
3811 * lib-load.adb (Load_Main_Source): Set Generate_Code flag on the
3813 (Make_Instance_Unit): Copy Generate_Code flag from the main unit
3815 * lib-writ.adb (Write_ALI): Remove redundant condition;
3816 Generate_Code flag is always set for the main unit.
3817 * par-load.adb (Load): Set Generate_Code flag on the main unit's
3818 corresponding spec, if any.
3820 2021-07-07 Dmitriy Anisimkov <anisimko@adacore.com>
3822 * libgnat/g-socket.ads (Option_Name): Add Keep_Alive_Count,
3823 Keep_Alive_Idle, and Keep_Alive_Interval items to enumeration.
3824 (Option_Type): Add Keep_Alive_Count, Keep_Alive_Idle, and
3825 Keep_Alive_Interval alternatives to the case of discriminated
3827 * libgnat/g-socket.adb (Options): Add Keep_Alive_Count,
3828 Keep_Alive_Idle, and Keep_Alive_Interval to items enumerator to
3829 OS constant converter.
3830 (Set_Socket_Option): Process Keep_Alive_Count, Keep_Alive_Idle,
3831 and Keep_Alive_Interval socket options.
3832 (Get_Socket_Option): Idem.
3834 2021-07-07 Piotr Trojanek <trojanek@adacore.com>
3836 * lib-writ.adb (Write_ALI): Exit from loop after seeing first
3837 unit that violates No_Elaboration_Code restriction.
3839 2021-07-07 Piotr Trojanek <trojanek@adacore.com>
3841 * inline.adb (Instantiate_Bodies): Fix white in declaration.
3842 (Remove_Dead_Instance): Change iteration from WHILE to FOR.
3844 2021-07-07 Bob Duff <duff@adacore.com>
3846 * checks.adb, exp_attr.adb, exp_ch4.adb, exp_ch6.adb,
3847 exp_ch9.adb, exp_disp.adb, exp_util.adb, inline.adb,
3848 sem_res.adb: Change all calls to Make_Unchecked_Type_Conversion
3849 to call Unchecked_Convert_To instead. This involves removing
3850 New_Occurrence_Of on the first parameter, because
3851 Unchecked_Convert_To expects a type entity, rather than the name
3852 of one. Also, removed calls to Relocate_Node, because
3853 Unchecked_Convert_To takes care of that.
3854 * sinfo.ads: Change comment to be worded more firmly.
3856 2021-07-07 Steve Baird <baird@adacore.com>
3858 * libgnarl/s-tassta.adb (Free_Task): Acquire the Task_Lock
3859 before, rather than after, querying the task's Terminated flag.
3860 Add a corresponding Task_Unlock call.
3862 2021-07-06 Bob Duff <duff@adacore.com>
3864 * atree.ads (Current_Error_Node): Initialize to Empty.
3866 2021-07-06 Steve Baird <baird@adacore.com>
3868 * exp_put_image.adb: Eliminate references to
3869 Debug_Flag_Underscore_Z. Change the meaning of the function
3870 Enable_Put_Image. Previously, a result of False for a tagged
3871 type would mean that the type does not get a Put_Image (PI)
3872 routine at all. Now, it means that the type gets a PI routine
3873 with very abbreviated functionality (just a call to
3874 Unknown_Put_Image). This resolves problems in mixing code
3875 compiled with and without the -gnat2022 switch.
3876 * exp_ch3.adb: Enable_Put_Image no longer participates in
3877 determining whether a tagged type gets a Put_Image procedure. A
3878 tagged type does not get a Put_Image procedure if the type
3879 Root_Buffer_Type is unavailable. This is needed to support cross
3880 targets where tagged types are supported but the type
3881 Root_Buffer_Type is not available.
3882 * exp_dist.adb: Add workarounds for some problems that arise
3883 when using the (obsolete?) Garlic implementation of the
3884 distributed systems annex with Ada 2022 constructs.
3885 * libgnat/a-sttebu.ads: Workaround a bootstrapping problem.
3886 Older compilers do not support raise expressions, so revise the
3887 the Pre'Class condition to meet this requirement without
3888 changing the condition's behavior at run time.
3890 2021-07-06 Eric Botcazou <ebotcazou@adacore.com>
3892 * repinfo-input.adb (JSON_Entity_Kind, Read_Variant_Part): Fix
3895 2021-07-06 Steve Baird <baird@adacore.com>
3897 * sem_ch5.adb (Analyze_Assignment): Add new nested function,
3898 Omit_Range_Check_For_Streaming, and make call to
3899 Apply_Scalar_Range_Check conditional on the result of this new
3901 * exp_attr.adb (Compile_Stream_Body_In_Scope): Eliminate Check
3902 parameter, update callers. The new
3903 Omit_Range_Check_For_Streaming parameter takes the place of the
3904 old use of calling Insert_Action with Suppress => All_Checks,
3905 which was insufficiently precise (it did not allow suppressing
3906 checks for one component but not for another).
3907 (Expand_N_Attribute_Reference): Eliminate another "Suppress =>
3908 All_Checks" from an Insert_Action call, this one in generating
3909 the expansion of a T'Read attribute reference for a composite
3912 2021-07-06 Ghjuvan Lacambre <lacambre@adacore.com>
3914 * sem_ch5.adb (Analyze_Loop_Parameter_Specification): Check for
3915 empty loops caused by constraints.
3917 2021-07-06 Nicolas Roche <roche@adacore.com>
3919 * rtinit.c (skip_quoted_string): Handle malformed command line
3920 with no closing double quote.
3921 (skip_argument): Handle case in which a null character is
3922 encountered by skip_quote_string.
3924 2021-07-06 Piotr Trojanek <trojanek@adacore.com>
3926 * uname.adb (Add_Node_Name): Replace local constant whose
3927 initial expression was evaluated even when unnecessary with just
3928 that expression that is evaluated at most once and only when
3931 2021-07-06 Piotr Trojanek <trojanek@adacore.com>
3933 * lib.adb (Remove_Unit): Replace defensive code with an
3935 * par-load.adb (Load): Address a question mark in the comment.
3937 2021-07-06 Piotr Trojanek <trojanek@adacore.com>
3939 * sem_util.adb (Enclosing_Comp_Unit_Node): When the loop exits
3940 the Current_Node is either an N_Compilation_Unit node or Empty,
3941 so simply return it without redundant checks.
3943 2021-07-06 Piotr Trojanek <trojanek@adacore.com>
3945 * lib-load.adb (Load_Unit): Remove excessive whitespace.
3946 * lib.adb (Is_Internal_Unit, Is_Predefined_Unit): Likewise.
3947 * par-ch10.adb (P_Compilation_Unit): Simplify with membership
3949 * par-load.adb (Load): Likewise.
3950 * uname.adb (Get_Unit_Name): Likewise.
3952 2021-07-06 Piotr Trojanek <trojanek@adacore.com>
3954 * lib-writ.adb (Ensure_System_Dependency): Simplify by reusing a
3957 2021-07-06 Steve Baird <baird@adacore.com>
3960 (Expand_N_Case_Statement.Expand_General_Case_Statement.Pattern_Match):
3961 When generating an equality test for a statically known discrete
3962 value, only generate the numeric value if the discrete type is
3963 not an enumeration type. If it is an enumeration type, then
3964 call Get_Enum_Lit_From_Pos instead.
3966 2021-07-06 Justin Squirek <squirek@adacore.com>
3968 * par-ch6.adb (Get_Return_Kind): Removed.
3969 (Is_Extended): Created to identify simple and "when" return
3970 statements from extended return statements.
3971 (P_Return_Statement): Merged simple and "when" return statement
3974 2021-07-06 Gary Dismukes <dismukes@adacore.com>
3976 * sem_ch4.adb (Try_One_Prefix_Interpretation): Augment test of
3977 "not Extensions_Allowed" with test for absence of Obj_Type's
3978 primitive operations Elist, as an additional condition for early
3979 return from this procedure.
3981 2021-07-06 Gary Dismukes <dismukes@adacore.com>
3983 * exp_ch4.adb (Process_Transient_In_Expression): In one comment,
3984 fix two typos and reorder wording of one sentence, plus minor
3987 2021-07-06 Justin Squirek <squirek@adacore.com>
3989 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove
3990 legacy expansion of element iterators, and use expansion form
3991 used by unconstrained element types in the general case.
3993 2021-07-06 Ed Schonberg <schonberg@adacore.com>
3995 * exp_ch4.adb (Process_Transient_In_Expression): Ensure that
3996 Fin_Context, used to insert finalization code for the
3997 expression, is a list member: the value returned by
3998 Find_Hook_Context may be an expression node when the transient
3999 is part of a larger expression and it has a non-boolean type.
4001 2021-07-06 Yannick Moy <moy@adacore.com>
4003 * sem_case.adb: Fix error message.
4005 2021-07-06 Bob Duff <duff@adacore.com>
4007 * tbuild.adb (Convert_To): Add assert, along with a comment.
4008 (Make_DT_Access): Remove this function, which is not used. It
4009 was incorrect anyway (the call to New_Occurrence_Of should not
4011 (Unchecked_Convert_To): Add assert. The previous version's test
4012 for unchecked conversion to the same type was redundant and
4013 could never be true, because the previous 'if' already checked
4014 for ANY expression of the same type. Remove that, and replace
4015 with a test for unchecked conversion to a related type.
4016 Otherwise, we somethings get things like
4017 "finalize(some_type!(some_type!(x)))" in the generated code,
4018 where x is already of type some_type, but we're converting it to
4019 the private type and then to the full type or vice versa (so the
4020 types aren't equal, so the previous 'if' doesn't catch it).
4021 Avoid updating the Parent. This is not necessary; the Parent
4022 will be updated if/when the node is attached to the tree.
4023 * tbuild.ads: Fix comments. No need to say "this is safe" when
4024 we just explained that a few lines earlier. Remove
4026 * sinfo.ads: Add comments.
4027 * exp_ch7.adb (Make_Finalize_Address_Stmts): Minor comment fix.
4028 * gen_il-gen.adb, gen_il-gen.ads, gen_il-gen-gen_nodes.adb,
4029 gen_il-internals.ads: Implement a feature where you can put:
4030 Nmake_Assert => "expr" where expr is a boolean expression in a
4031 call to Create_Concrete_Node_Type. It is added in a pragma
4032 Assert in the Nmake.Make_... function for that type.
4034 2021-07-06 Gary Dismukes <dismukes@adacore.com>
4036 * checks.adb: Remove calls of Set_Do_Tag_Check (N, False).
4037 * einfo.ads: Remove hanging unneeded ??? comment ("this real description

4047 mention out-mode parameters as well, and remove ???.
4048 (Propagate_Concurrent_Flags): Minor reformatting.

4055 formals of mode out as well.
4056 * sinfo.ads: Remove ??? comment about flag
4057 Convert_To_Return_False indicating that the flag is obsolete (in
4058 fact it's used). Remove references to Do_Accessibility_Check and
4059 Do_Tag_Check (and the two associated ??? comments), as these

4074 * exp_ch7.adb (Establish_Transient_Scope): Misc cleanups and
4075 comment improvements.
4076 (Set_Node_To_Be_Wrapped): Remove -- not worth putting this code
4077 in a separate procedure, called only once.
4078 * sem_util.adb (Requires_Transient_Scope): Assert that our
4079 parameter has the right Kind. It probably shouldn't be E_Void,
4080 but that is passed in in some cases.
4081 (Ensure_Minimum_Decoration): Move the call later, so we know Typ
4082 is Present, and remove "if Present (Typ)" from this procedure.
4083 * exp_aggr.adb (Convert_To_Assignments): Use membership test,
4084 and avoid the "if False" idiom.

4087 rules for aggregates.

4090 Establish_Transient_Scope.

4092 (Clear): Remove "pragma Warnings (Off);", which wasn't actually
4093 suppressing any warnings.
4095 2021-07-06 Bob Duff <duff@adacore.com>
4097 * gen_il-gen-gen_nodes.adb: Change the parent of

4103 the name of an assignment operation do not apply predicate check
4104 to it prior to the assignment.
4106 2021-07-06 Bob Duff <duff@adacore.com>
4108 * libgnat/a-conhel.adb: Assert that tampering counts remain
4109 between 0 and 2**31-1. This makes debugging of
4110 finalization-related bugs easier.
4112 2021-07-06 Doug Rupp <rupp@adacore.com>
4114 * Makefile.rtl (LIBGNAT_TARGET_PAIRS): Use s-osprim__posix.adb

4123 2021-07-06 Gary Dismukes <dismukes@adacore.com>
4125 * doc/gnat_rm/implementation_defined_pragmas.rst: Add a
4126 description of the feature of prefixed-view calls for untagged
4127 types to the section on pragma Extensions_Allowed.
4128 * gnat_rm.texi: Regenerate.
4129 * einfo.ads: Update specification for
4130 Direct_Primitive_Operations to reflect its use for untagged
4131 types when Extensions_Allowed is True.
4132 * gen_il-gen-gen_entities.adb: Allow Direct_Primitive_Operations
4133 as a field of untagged classes of types by removing the "Pre"
4134 test of "Is_Tagged_Type (N)", and making that field generally
4135 available for all types and subtypes by defining it for
4136 Type_Kind and removing its specification for individual classes
4138 * sem_ch3.adb (Analyze_Full_Type_Declaration): Initialize the
4139 Direct_Primitive_Operations list when not already set for the
4140 new (sub)type and its base type (except when Ekind of the type
4141 is E_Void, which can happen due to errors in cases where
4142 Derived_Type_Declaration is called and perhaps in other
4144 (Analyze_Subtype_Declaration): Inherit
4145 Direct_Primitive_Operations list from the base type, for record
4147 (Build_Derived_Record_Type): Initialize the
4148 Direct_Primitive_Operations list for derived record and private

4151 list for derived types (and also for their associated base types
4153 (Process_Full_View): For full types that are untagged record and
4154 private types, copy the primitive operations of the partial view
4155 to the primitives list of the full view.
4156 * sem_ch4.adb (Analyze_Selected_Component): Allow prefixed
4157 notation for subprogram calls in the case of untagged
4158 types (when Extensions_Allowed is True). In the case where
4159 Is_Private_Type (Prefix_Type) is True, call Try_Object_Operation
4160 when a discriminant selector wasn't found. Also call
4161 Try_Object_Operation in other type kind cases (when
4162 Extensions_Allowed is True).
4163 (Try_Object_Operation.Try_One_Prefixed_Interpretation): Prevent
4164 early return in the untagged case (when Extensions_Allowed is
4165 True). Condition main call to Try_Primitive_Operation on the
4166 type having primitives, and after that, if Prim_Result is False,
4167 test for case where the prefix type is a named access type with
4168 primitive operations and in that case call
4169 Try_Primitive_Operation after temporarily resetting Obj_Type to
4170 denote the access type (and restore it to the designated type
4172 (Try_Object_Operation.Valid_First_Argument_Of): Do matching type
4173 comparison by testing Base_Type (Obj_Type) against
4174 Base_Type (Typ), rather than against just Typ, to properly
4175 handle cases where the object prefix has a constrained
4176 subtype. (Fixes a bug discovered while working on this
4179 (New_Overloaded_Entity.Check_For_Primitive_Subprogram): Add a
4180 primitive of an untagged type to the type's list of primitive
4181 operations, for both explicit and implicit (derived, so
4182 Comes_From_Source is False) subprogram declarations. In the case
4183 where the new primitive overrides an inherited subprogram,
4184 locate the primitives Elist that references the overridden
4185 subprogram, and replace that element of the list with the new
4186 subprogram (done by calling the new procedure
4187 Add_Or_Replace_Untagged_Primitive on the result type and each
4189 (Check_For_Primitive_Subprogram.Add_Or_Replace_Untagged_Primitive):
4190 New nested procedure to either add or replace an untagged
4191 primitive subprogram in a given type's list of primitive
4192 operations (replacement happens in case where the new subprogram
4193 overrides a primitive of the type).
4194 * sem_ch7.adb (New_Private_Type): When Extensions_Allowed is
4195 True, initialize the Direct_Primitive_Operations list of a
4196 private type to New_Elmt_List in the case of untagged types.
4197 * sem_ch8.adb (Find_Selected_Component): In the case where the
4198 prefix is an entity name, relax condition that tests
4199 Has_Components so that Analyze_Selected_Component will also be
4200 called when Extensions_Allowed is True and the prefix type is
4203 2021-07-06 Ed Schonberg <schonberg@adacore.com>
4205 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not perform
4206 conformance check when the subprogram body has been created for
4207 an expression function that is not a completion of a previous
4208 specification, because the profile of the constructed body is
4209 copied from the expression function itself.
4211 2021-07-06 Steve Baird <baird@adacore.com>
4213 * doc/gnat_rm/implementation_of_specific_ada_features.rst: Add a
4214 warning indicating that the details of the default (i.e.,
4215 selected by the compiler) implementation of T'Put_Image for a
4216 nonscalar type T are subject to change.
4217 * gnat_rm.texi: Regenerate.

4281 2021-07-05 Steve Baird <baird@adacore.com>
4283 * exp_ch3.adb (Build_Record_Init_Proc.Build_Assignment): When
4284 building the assignment statement corresponding to the default
4285 expression for a component, we make a copy of the expression.
4286 When making that copy (and if we have seen a component that
4287 requires late initialization), pass a Map parameter into the
4288 call to New_Copy_Tree to redirect references to the type to
4289 instead refer to the _Init formal parameter of the init proc.
4290 This includes hoisting the declaration of Has_Late_Init_Comp out
4291 one level so that it becomes available to Build_Assignment.
4292 (Find_Current_Instance): Return True for other kinds of current
4293 instance references, instead of just access-valued attribute
4294 references such as T'Access.
4295 * sem_util.adb (Is_Aliased_View): Return True for the _Init
4296 formal parameter of an init procedure. The changes in
4297 exp_ch3.adb can have the effect of replacing a "T'Access"
4298 attribute reference in an init procedure with an "_Init'Access"
4299 attribute reference. We want such an attribute reference to be
4300 legal. However, we do not simply mark the formal parameter as
4301 being aliased because that might impact callers.

4303 True for the prefix of an Image (or related attribute) attribute

4479 when within an instance and the type of the component hss a
4480 private ancestor: the instantiation is legal if the generic
4481 compiles, and spurious errors may be generated otherwise.

4495 already have one, just as is done for (for example) the
4496 streaming-related Read procedure.

4498 (Build_Record_Put_Image_Procedure.Make_Component_Attributes): Do
4499 not treat _Parent component like just another component, for two
4500 reasons. 1. If the _parent component's type has a
4501 user-specified Put_Image procedure, then we want to generate a
4502 call to that procedure and then generate extension aggregate
4503 syntax. 2. Otherwise, we still don't want to see any mention of
4504 "_parent" in the generated image text.

4510 prefix in order to help with expansion needed in the class-wide
4511 case (where the prefix is also referenced in the call to
4512 Wide_Wide_Expanded_Name) if evaluation of the prefix has side
4513 effects. Add new local helper function, Put_String_Exp. Add
4514 support for case where prefix type is class-wide.
4515 (Enable_Put_Image, Preload_Root_Buffer_Type): Query Ada_Version
4516 > Ada_2022 instead of (indirectly) querying -gnatd_z switch.
4517 * freeze.adb (In_Expanded_Body): A one-line change to add
4518 TSS_Put_Image to the list of subprograms that have
4519 expander-created bodies.
4520 * rtsfind.ads: Add support for accessing
4521 Ada.Tags.Wide_Wide_Expanded_Name.
4522 * sem_ch3.ads, sem_ch3.adb: Delete Is_Null_Extension function,
4523 as part of moving it to Sem_Util.
4525 (Analyze_Put_Image_TSS_Definition.Has_Good_Profile): Improve
4526 diagnostic messages in cases where the result is going to be
4527 False and the Report parameter is True. Relax overly-restrictive
4528 checks in order to implement mode conformance.
4529 (Analyze_Stream_TSS_Definition.Has_Good_Profile): Add similar
4530 relaxation of parameter subtype checking for the Stream
4531 parameter of user-defined streaming subprograms.
4532 * sem_disp.adb (Check_Dispatching_Operation): A one-line
4533 change (and an accompanying comment change) to add TSS_Put_Image
4534 to the list of compiler-generated dispatching primitive
4536 * sem_util.ads, sem_util.adb: Add Ignore_Privacy Boolean
4537 parameter to Is_Null_Record_Type function (typically the
4538 parameter will be False when the function is being used in the
4539 implementation of static semantics and True for dynamic
4540 semantics; the parameter might make a difference in the case of,
4541 for example, a private type that is implemented as a null record
4542 type). Add related new routines Is_Null_Extension (formerly
4543 declared in Sem_Ch3), Is_Null_Extension_Of, and
4544 Is_Null_Record_Definition.
4546 2021-07-05 Justin Squirek <squirek@adacore.com>
4548 * freeze.adb (Freeze_Profile): Use N's Sloc, F_type's chars.
4550 2021-07-05 Bob Duff <duff@adacore.com>

4553 sem_util.adb, sem_util.ads: Change L and H to be First and Last,
4554 to match the attributes in the RM. Change calls from procedure
4555 to function where appropriate.
4557 2021-07-05 Bob Duff <duff@adacore.com>
4559 * sem_util.ads, sem_util.adb (Compute_Returns_By_Ref): New
4560 procedure to compute Returns_By_Ref, to avoid some code
4561 duplication. This will likely change soon, so it's good to have
4562 the code in one place.
4563 (CW_Or_Has_Controlled_Part): Move here from Exp_Ch7, because
4564 it's called by Compute_Returns_By_Ref, and this is a better
4565 place for it anyway.
4566 (Needs_Finalization): Fix comment to be vague instead of wrong.
4567 * exp_ch6.adb (Expand_N_Subprogram_Body, Freeze_Subprogram):
4568 Call Compute_Returns_By_Ref.
4569 * sem_ch6.adb (Check_Delayed_Subprogram): Call
4570 Compute_Returns_By_Ref.
4571 * exp_ch7.ads, exp_ch7.adb (CW_Or_Has_Controlled_Part): Move to

4587 * exp_attr.adb (Get_Integer_Type): Return an integer type with the
4588 same signedness as the input type.

4595 2021-06-29 Piotr Trojanek <trojanek@adacore.com>
4598 (Unknown_Alignment): Simply negate the Known_ counterpart.
4599 (Unknown_Component_Bit_Offset): Likewise.
4600 (Unknown_Esize): Likewise.
4601 (Unknown_Normalized_First_Bit): Likewise.
4602 (Unknown_Normalized_Position): Likewise.
4603 (Unknown_Normalized_Position_Max): Likewise.
4604 (Unknown_RM_Size): Likewise.
4606 2021-06-29 Boris Yakobowski <yakobowski@adacore.com>
4608 * exp_ch4.adb (Expand_N_Op_Mod): Remove special case for mod -1

4619 2021-06-29 Bob Duff <duff@adacore.com>
4621 * sem_ch13.adb (Analyze_Record_Representation_Clause): Call
4622 Set_Entity_With_Checks instead of Set_Entity, so we perform the
4623 check for correct casing.
4624 * style.adb (Check_Identifier): Minor comment improvement.
4625 Cleanup overly complicated code.
4627 2021-06-29 Ed Schonberg <schonberg@adacore.com>
4629 * exp_aggr.adb (Convert_Aggr_In_Object_Decl): After expansion of
4630 the aggregate, the expression can be removed from the
4631 declaration, except if the object is class-wide, in which case
4632 the aggregate provides the actual type. In other cases the
4633 presence of the expression may lead to spurious freezing issue.
4634 * exp_ch3.adb (Expand_N_Object_Declaration): If the expression
4635 in the declaration is an aggregate with delayed expansion (as is
4636 the case for objects of a limited type, or a subsequent address
4637 specification) the aggregate must be resolved at this point.
4638 This resolution must not include expansion, because the
4639 expansion of the enclosing declaration will construct the
4640 necessary aggregate expansion.
4642 2021-06-29 Piotr Trojanek <trojanek@adacore.com>
4644 * errout.ads (Adjust_Name_Case): Remove obsolete and now unused
4646 * errout.adb (Adjust_Name_Case): Likewise; fix variant that uses

4656 * adaint.c (__gnat_portable_spawn): Revert change that
4657 introduced setting of __gnat_in_child_after_fork.
4659 2021-06-29 Patrick Bernardi <bernardi@adacore.com>
4661 * libgnarl/s-tasdeb.ads (Known_Tasks): Add Atomic_Components

4686 2021-06-29 Piotr Trojanek <trojanek@adacore.com>
4688 * sem_ch3.adb (Analyze_Declarations): Remove explicit check for
4689 missing, because a subsequent call to Is_Empty_List will detect
4692 2021-06-29 Piotr Trojanek <trojanek@adacore.com>
4694 * freeze.adb (Freeze_All): Simplify by reusing
4695 Is_Subprogram_Or_Entry.
4696 * sem_ch11.adb (Analyze_Handled_Statement): Likewise.
4698 2021-06-29 Piotr Trojanek <trojanek@adacore.com>
4700 * sem_warn.adb (Warn_On_Overlapping_Actuals): Prevent cascaded
4701 errors once for the subprogram call, not for every pair of
4704 2021-06-29 Piotr Trojanek <trojanek@adacore.com>
4706 * sem_ch3.adb (Is_Local_Type): Simplify by reusing Scope_Within.
4708 2021-06-29 Gary Dismukes <dismukes@adacore.com>
4710 * sem_ch6.ads (Can_Override_Operator): Function declaration
4711 moved from package body to package spec.
4712 * sem_ch6.adb (Check_Overriding_Indicator): Now use test of
4713 whether the subprogram's Chars is an operator name, to handle
4714 cases of function instances whose entity is
4715 N_Defining_Identifier rather than N_Defining_Operator_Symbol.
4716 (Can_Override_Operator): Function declaration moved to package
4717 spec. Now use test of whether the subprogram's Chars is an
4718 operator name, to handle cases of function instances whose
4719 entity is N_Defining_Identifier rather than
4720 N_Defining_Operator_Symbol.
4721 * sem_ch8.adb (Analyze_Renamed_Subprogram): Check for
4722 possibility of an overridden predefined operator, and suppress
4723 the "not overriding" message in that case.
4725 2021-06-29 Doug Rupp <rupp@adacore.com>
4727 * Makefile.rtl: Add a new ifeq for vx7r2 shared gnatlib.
4729 2021-06-29 Piotr Trojanek <trojanek@adacore.com>
4731 * exp_attr.adb (Build_Array_VS_Func): Restore uses of

4783 documentation: Repinfo is the package where these negative
4784 values are documented.
4785 * einfo-utils.adb (Known_Component_Size,
4786 Known_Static_Component_Size, Unknown_Component_Size): Remove
4787 calls to Implementation_Base_Type, because Component_Size is an
4788 Impl_Base_Type_Only field (see Gen_Entities).
4789 * sem_ch13.ads, sem_ch13.adb (Check_Size): Do not set Esize and
4790 RM_Size. This is unnecessary in the case of Size. For
4791 Component_Size, it is wrong, because we would be setting the
4792 Esize and RM_Size of the component type.
4794 2021-06-29 Pascal Obry <obry@adacore.com>
4796 * s-oscons-tmplt.c: Add some OS constants.

4811 Allocatable_Kind): Add new abstract kinds.
4812 (Constant_Or_Variable_Kind): Likewise.
4813 (E_Constant, E_Variable, E_Loop_Parameter): Use them.

4821 * gen_il-internals.ads, gen_il-internals.adb: (Pos): Remove this
4822 function. It was assuming that the order of the enumeration
4823 literals in Type_Enum is the same as the order of the generated
4824 types Node_Kind and Entity_Kind, which is not true.

4841 qualified_expression where the qualifying subtype is an
4842 unconstrained array subtype with fixed lower bounds for some of
4843 its indexes, generate tests to check that those bounds are equal
4844 to the corresponding lower bounds of the qualified array object.
4846 2021-06-21 Bob Duff <duff@adacore.com>
4848 * libgnat/s-valuen.ads (Value_Enumeration,
4849 Valid_Enumeration_Value): Inline.

4872 * par-ch6.adb (Get_Return_Kind): Renamed from Is_Simple and
4873 processing added for "return ... when" return kind.
4874 (Is_Simple): Renamed to Get_Return_Kind.
4875 (P_Return_Statement): Add case for return ... when variant of
4877 * par-util.adb, par.adb (Missing_Semicolon_On_When): Added to

4896 in the GNATRTL_NONTASKING_OBJS list.
4897 * exp_put_image.ads, exp_put_image.adb: Update Rtsfind calls to
4898 match new specs. For example, calls to RE_Sink are replaced with
4899 calls to RE_Root_Buffer_Type. Update comments and change
4900 subprogram names accordingly (e.g., Preload_Sink is changed to
4901 Preload_Root_Buffer_Type).
4902 * impunit.adb: Add 6 new predefined units (Text_Buffers and 5
4903 child units thereof).
4904 * rtsfind.ads, rtsfind.adb: Add interfaces for accessing the
4905 Ada.Strings.Text_Buffers package and declarations
4906 therein (including the Unbounded child unit). Do not (yet)

4930 Sink'Class with Sink throughout. Use string concatenation and
4931 LF marker instead of formatted strings and "\n" marker. Update
4932 Indent/Outdent calls to use new Increase_Indent/Decrease_Indent
4934 (Put_Membership_Query_Decl): Remove.
4935 * gen_il-internals.ads: Replace Sink'Class with Sink throughout.
4937 (Pfields): Likewise.

4990 libgnat/a-stbuun.ads, libgnat/a-stbuun.adb,
4991 libgnat/a-stbuut.ads, libgnat/a-stbuut.adb: A new predefined
4992 unit, Ada.Strings.Text_Buffers, and five child units. Two of
4993 the five are RM-defined: Bounded and Unbounded. The remaining
4994 three are GNAT-defined: Files, Utils, and Formatting. The buffer
4995 type corresponding to an output file, type Files.File_Buffer, is
4996 simpler (and perhaps therefore slower) than its predecessor.
4997 Caching similar to what was being done before could be added
4998 later if that seems appropriate.
4999 * libgnat/s-putima.ads: Modify context clause, update
5000 declaration of subtype Sink to refer to
5001 Text_Buffers.Root_Buffer_Type instead of the old
5002 Text_Output.Sink type.
5003 * libgnat/s-putima.adb: Modify context clause. Update
5004 Indent/Outdent calls to use new Increase_Indent/Decrease_Indent
5005 names; ditto for "Put_String => Put" name change.

5011 ordering is in effect for the operands and they are small,
5012 adjust the unchecked conversions done around them.
5014 2021-06-21 Richard Kenner <kenner@adacore.com>

5024 libgnat/s-bituti.ads (Fast_Copy_Bitfield): New run-time library
5025 function to copy bit fields faster than Copy_Bitfield. Cannot be
5026 called with zero-size bit fields. Remove obsolete ??? comments
5027 from s-bituti.adb; we already do "avoid calling this if
5028 Forwards_OK is False".
5029 * exp_ch5.adb (Expand_Assign_Array_Loop_Or_Bitfield,
5030 Expand_Assign_Array_Bitfield_Fast): Generate calls to
5031 Fast_Copy_Bitfield when appropriate.
5032 * sem_util.adb, sem_util.ads (Get_Index_Bounds): Two new
5033 functions for getting the index bounds. These are more
5034 convenient than the procedure of the same name, because they can
5035 be used to initialize constants.
5037 2021-06-21 Ed Schonberg <schonberg@adacore.com>
5039 * gen_il-fields.ads: Add Default_Subtype_Mark to enumeration
5041 * gen_il-gen-gen_nodes.adb: Add call to create new field for
5042 Formal_Type_Declaration node.
5043 * par-ch12.adb (P_Formal_Type_Declaration): in Ada_2022 mode,
5044 recognize new syntax for default: "or use subtype_mark".
5045 (P_Formal_Type_Definition): Ditto for the case of a formal
5047 * sinfo.ads: Add field Default_Subtype_Mark to
5048 N_Formal_Type_Declaration.
5049 * sem_ch12.adb (Validate_Formal_Type_Default): New procedure, to
5050 apply legality rules to default subtypes in formal type
5051 declarations. Some legality rules apply to all defaults, such as
5052 the requirement that the default for a formal type that depends
5053 on previous formal entities must itself be a previously declared
5054 formal of the same unit. Other checks are kind- specific.
5055 (Analyze_Associations): Use specified default if there is no
5056 actual provided for a formal type in an instance.
5057 (Analyze_Formal_Type_Declaration): Call
5058 Validate_Formal_Type_Default when default subtype is present.
5060 2021-06-21 Bob Duff <duff@adacore.com>
5062 * libgnat/s-valuen.ads, libgnat/s-valuen.adb
5063 (Value_Enumeration_Pos): New function to compute the 'Pos of the

5065 instead of raising an exception on invalid input. Called by both
5066 Valid_Enumeration_Image and Value_Enumeration.
5067 (Valid_Enumeration_Image): Return a Boolean indicating whether
5068 the String is a valid Image for the given enumeration type.
5069 (Value_Enumeration): Implement in terms of
5070 Value_Enumeration_Pos.
5071 * libgnat/s-vaenu8.ads, libgnat/s-vaen16.ads,
5072 libgnat/s-vaen32.ads: Rename Valid_Enumeration_Image from the
5074 * libgnat/s-valuti.ads: Correct documentation (it was not true
5075 for the null string).
5076 * libgnat/s-valuti.adb (Normalize_String): Do not raise
5077 Constraint_Error for the null string, nor strings containing
5078 nothing but blanks, so that Valid_Enumeration_Image can return
5079 False in these cases, rather than raising an exception.
5080 * rtsfind.ads (RE_Value_Enumeration_8, RE_Value_Enumeration_16,
5081 RE_Value_Enumeration_32): New functions.
5082 (RTE_Available): Improve comment (E doesn't have to be a
5083 subprogram, although that's the usual case).
5084 * sem_attr.adb (nalid_Value): Semantic analysis for new
5086 * exp_attr.adb: Call Expand_Valid_Value_Attribute for new
5088 * exp_imgv.ads, exp_imgv.adb (Expand_Valid_Value_Attribute): New
5089 procedure to expand Valid_Value into a call to
5090 Valid_Enumeration_Image_NN.
5091 (Expand_Value_Attribute): Misc code cleanups. Remove two ???
5092 mark comments. RTE_Available won't work here. For one thing,
5093 RTE_Available (X) shouldn't be called until the compiler has
5094 decided to make use of X (see comments on RTE_Available), and in
5095 this case we're trying to AVOID calling something.
5096 * snames.ads-tmpl: New attribute name.
5097 * doc/gnat_rm/implementation_defined_attributes.rst: Document
5099 * gnat_rm.texi: Regenerate.

5146 specially and rewrite handling of numbers in other bases.

5150 * repinfo.adb (List_Type_Info): When the output is to JSON, call
5151 UR_Write_To_JSON instead of UR_Write.

5202 * gen_il-gen.adb: Improve comments.
5203 * snames.ads-tmpl (Convention_Id): Remove "-- Plenty of space
5204 for expansion", because that's irrelevant now that we are no
5205 longer laying out node fields by hand.
5207 2021-06-18 Piotr Trojanek <trojanek@adacore.com>
5209 * sem_util.adb (Denotes_Same_Object): Handle character literals
5210 just like integer literals.

5218 2021-06-18 Bob Duff <duff@adacore.com>
5220 * sprint.adb (Write_Source_Line): Check for EOF in
5221 Line_Terminator loop. Note that when a source file is read in,

5227 the kind of the of parameter and returned node.
5228 * sem_ch12.adb (Remove_Parent): Reorder conditions; this change

5493 * checks.adb (Discrete_Range_Cond): For an index subtype that
5494 has a fixed lower bound, require that the range's lower bound
5495 match that of the subtype.
5496 (Selected_Range_Checks): Warn about the case where a static
5497 lower bound does not equal an index subtype's fixed lower bound.

5511 (Expand_Sliding_Conversion): New procedure for applying a
5512 sliding subtype conversion to an array object of a
5513 fixed-lower-bound subtype when needed. It traverses the indexes
5514 of the unconstrained array type/subtype to create a target
5515 constrained subtype and rewrites the array object to be a
5516 conversion to that subtype, when there's at least one index
5517 whose lower bound does not statically match the fixed-lower
5518 bound of the target subtype.

5531 for parsing unconstrained index ranges.
5532 (P_Index_Or_Discriminant_Constraint): Add handling for parsing

5535 language extensions are not enabled.
5536 * sem_ch3.adb (Analyze_Object_Declaration): If the object's

5543 (Constrain_Array): For an array subtype with one or more index
5544 ranges specifying a fixed lower bound, set Is_Constrained to
5545 False and set the array subtype's

5547 (Constrain_Index): Mark the subtypes of an index that specifies
5548 a fixed lower bound as being a fixed-lower-bound index subtype,
5549 and set the High_bound of the range of such an index to the
5550 upper bound of the base type of the array type's corresponding
5552 * sem_res.adb (Resolve_Actuals): If a formal is of an
5553 unconstrained array subtype with fixed lower bound, then
5554 Expand_Sliding_Conversion is applied to the actual.
5555 * sem_util.adb (Build_Actual_Subtype): If the actual subtype
5556 corresponds to an unconstrained array subtype having any indexes
5557 with fixed lower bounds, then set the lower bounds of any such
5558 indexes of the actual subtype to the appropriate fixed lower
5559 bound of the formal subtype (rather than taking it from the
5561 * sprint.adb (Sprint_Node_Actual, case N_Range): If a range's
5562 Etype has a fixed lower bound, then print "<>" rather than the
5563 High_Bound of the range.
5565 2021-06-17 Bob Duff <duff@adacore.com>
5567 * sem_util.adb, sem_util.ads (Has_Access_Values): New formal
5568 Include_Internal to indicate whether internal types should be
5570 * sem_warn.adb (Check_References): Change E_Out_Parameter to
5571 Formal_Kind, to match the comment about Spec_Entity. Pass
5572 Include_Internal => False to Has_Access_Values, so that we warn
5573 on types with access values that happen to be in internal types,
5574 such as Unbounded_String.
5575 * sem_attr.adb (Attribute_Has_Access_Values): Pass
5576 Include_Internal => True to Has_Access_Values, to preserve
5578 * libgnat/g-rewdat.adb (Do_Output): Change B from 'in out' to
5579 'in', to avoid warning enabled by the change to sem_warn.adb.

5587 (Expand_N_Case_Statement.Expand_General_Case_Statement): New
5589 (Expand_N_Case_Statement): If extensions are allowed and the
5590 case selector is not of a discrete type, then call
5591 Expand_General_Case_Statement to generate expansion instead of
5592 flagging the non-discrete selector as an error.
5593 * sem_case.ads (Is_Case_Choice_Pattern): New Boolean-valued
5594 function for testing whether a given expression occurs as part
5595 of a case choice pattern.
5596 * sem_case.adb (Composite_Case_Ops): New package providing
5597 support routines for the new form of case statements. This
5598 includes a nested package, Composite_Case_Ops.Value_Sets, which
5599 encapsulates the "representative values" implementation of
5600 composite value sets.
5601 (Check_Choices.Check_Case_Pattern_Choices): New procedure for
5602 semantic checking of non-discrete case choices. This includes
5603 the checks pertaining to coverage and overlapping.
5604 (Check_Choices.Check_Composite_Case_Selector): New procedure for
5605 semantic checking of non-discrete case selectors.
5606 (Check_Choices): If extensions are allowed then a non-discrete
5607 selector type no longer implies that an error must have been
5608 flagged earlier. Instead of simply returning, call
5609 Check_Composite_Case_Selector and Check_Case_Pattern_Choices.
5610 (Is_Case_Choice_Pattern): Body of new function declared in
5612 * sem_ch5.adb (Analyze_Case_Statement): If extensions are
5613 allowed, then we can't use RM 5.4's "The selecting_expression is
5614 expected to be of any discrete type" name resolution rule.
5615 Handle the case where the type of the selecting expression is
5616 not discrete, as well as the new ambiguous-name-resolution error
5617 cases made possible by this change.
5618 * sem_res.adb (Resolve_Entity_Name): It is ok to treat the name
5619 of a type or subtype as an expression if it is part of a case
5620 choice pattern, as in "(Field1 => Positive, Field2 => <>)".
5621 * exp_aggr.adb (Expand_Record_Aggregate): Do not expand case
5623 * gen_il-fields.ads: Define two new node attributes,
5624 Binding_Chars and Multidefined_Bindings.
5625 * gen_il-gen-gen_nodes.adb: The new Multidefined_Bindings
5626 attribute is Boolean-valued and may be set on
5627 N_Case_Statement_Alternative nodes. The new Binding_Chars
5628 attribute is Name_Id-valued and may be set on
5629 N_Component_Association nodes.
5630 * par-ch4.adb (P_Record_Or_Array_Component_Association): When
5631 parsing a component association, check for both new syntax forms
5632 used to specify a bound value in a case-choice aggregate. In
5633 the case of a box value, an identifier may occur within the box,
5634 as in "Foo => <Abc>" instead of "Foo => <>". In the more general
5635 case, an expression (or a box) may be followed by "is
5636 <identifier>", as in
5637 "Foo => Bar is Abc" instead of just "Foo => Bar".
5638 * sem_aggr.adb (Resolve_Record_Aggregate): Do not transform box
5639 component values in a case-choice aggregate.

6088 is already checked for legality in Sem_Ch13, including renamed
6089 discriminants in a derived type.
6090 (Is_Confirming, Same_Name): For expanded names, only check
6091 matching of selector, because prefix may correspond to original

6239 message into an expression function,
6240 OK_Scope_For_Discrim_Value_Error_Messages. Call that new
6241 function in two places: the point where the same test was being

6261 indeed a base type when Set_Base_Type is called, but then the
6262 type is mutated into a subtype in rare cases.

6273 the ordering of Mutate_Kind and Set_Directly_Designated_Type;
6274 remove temporary setting of Ekind to E_Access_Type for building

6280 Directly_Designated_Type from E_Void, E_Private_Record,

6457 2021-05-10 Eric Botcazou <ebotcazou@adacore.com>
6459 * Make-generated.in (do_gen_il): Replace with...
6460 (ada/stamp-gen_il): ...this. Do not copy files into generated/.
6462 2021-05-10 Martin Liska <mliska@suse.cz>
6464 * gcc-interface/utils.c (def_builtin_1): Use startswith
6465 function instead of strncmp.
6467 2021-05-07 Piotr Trojanek <trojanek@adacore.com>
6469 * einfo-utils.adb (Is_Access_Object_Type): Use
6470 Directly_Designated_Type.
6471 (Is_Access_Subprogram_Type): Use Directly_Designated_Type.
6472 (Set_Convention): Use plain Ekind.
6473 * gen_il-gen-gen_entities.adb (Type_Kind): Use plain Ekind.
6474 * sem_ch3.adb (Access_Type_Declaration): When seeing an illegal
6475 completion with an access type don't attempt to decorate the
6476 completion entity; previously the entity had its Ekind set to
6477 E_General_Access_Type or E_Access_Type, but its Designated_Type
6478 was empty, which caused a crash in freezing. (Actually, the
6479 error recovery in the surrounding context is still incomplete,
6480 e.g. we will crash when the illegal completion is an access to
6481 an unknown identifier).
6483 2021-05-07 Bob Duff <duff@adacore.com>
6485 * par_sco.adb: Align with/use clauses.

6519 up ??? marks. Rename Set_Ekind to be Mutate_Ekind.
6520 * einfo.ads, sinfo.ads: Likewise. Change "definitive
6521 definition" to "official definition", because the former sounds

6559 2021-05-07 Bob Duff <duff@adacore.com>
6561 * sem_ch3.adb (Process_Incomplete_Dependents): Reset
6562 Private_Dependents field to zero before calling Set_Ekind. Also
6563 move Set_Etype to after Set_Ekind, because it's always best to
6564 set the Ekind as early as possible.

6716 2021-05-07 Bob Duff <duff@adacore.com>
6718 * atree.ads, atree.adb: Major rewrite to support variable-sized
6719 node types. Add pragmas Suppress and Assertion_Policy. We now
6720 have an extra level of indirection: Node_Offsets is a table
6721 mapping Node_Ids to the offset of the start of each node in
6722 Slots. Slots is a table containing one or more contiguous slots
6723 for each node. Each slot is a 32-bit unchecked union that can
6724 contain any mixture of 1, 2, 4, 8, and 32-bit fields that fits.
6725 The old low-level getters and setters (e.g. Flag123) are
6727 * gen_il-fields.ads, gen_il-gen-gen_entities.adb,
6728 gen_il-gen-gen_nodes.adb, gen_il-gen.adb, gen_il-gen.ads,
6729 gen_il-main.adb, gen_il-types.ads, gen_il-utils.adb,
6730 gen_il-utils.ads, gen_il.adb, gen_il.ads: New gen_il program
6731 that generates various Ada and C++ files. In particular, the
6732 following files are generated by gen_il: einfo-entities.adb
6733 einfo-entities.ads, gnatvsn.ads, nmake.adb, nmake.ads,
6734 seinfo.ads, seinfo_tables.adb, seinfo_tables.ads,
6735 sinfo-nodes.adb, sinfo-nodes.ads, einfo.h, and sinfo.h.
6736 * sinfo-utils.adb, sinfo-utils.ads, einfo-utils.adb,
6737 einfo-utils.ads: New files containing code that needs to refer
6738 to Sinfo.Nodes and Einfo.Entities. This code is mostly moved
6739 here from Sinfo and Einfo to break cycles.
6740 * back_end.adb: Pass node_offsets_ptr and slots_ptr to gigi,
6741 instead of nodes_ptr and flags_ptr. The Nodes and Flags tables
6742 no longer exist. (Note that gigi never used the Flags table.)
6743 * sinfo-cn.ads (Change_Identifier_To_Defining_Identifier,
6744 Change_Character_Literal_To_Defining_Character_Literal,
6745 Change_Operator_Symbol_To_Defining_Operator_Symbol): Turn N into
6747 * sinfo-cn.adb: Update. Add assertions, which can be removed at
6748 some point. Rewrite to use higher-level facilities. Make sure
6749 vanishing fields are zeroed out. Add with/use for new packages.
6750 * sem_util.adb: Remove "Assert(False)" immediately followed by
6751 "raise Program_Error". Use higher-level facilities such as
6752 Walk_Sinfo_Fields instead of depending on low-level Set_FieldN
6753 routines that no longer exist. Use Get_Comes_From_Source_Default
6754 instead of Default_Node.Comes_From_Source (Default_Node no
6755 longer exists). Use Set_Basic_Convention instead of
6756 Basic_Set_Convention. Add with/use for new packages.
6757 * sem_util.ads: The Convention field had getter Convention and
6758 setter Basic_Set_Convention. Make that more uniform: there is
6759 now a field called Basic_Convention, with Basic_Convention and
6760 Set_Basic_Convention as getter/setter, and write Convention and
6761 Set_Convention here.
6762 * nlists.adb: Rewrite to use abstractions, rather then depending
6763 on low-level implementation details of Atree. Necessary because
6764 those details have changed. Add with/use for new packages.
6765 * sem_ch12.adb: Use higher-level facilities such as
6766 Walk_Sinfo_Fields instead of depending on low-level Set_FieldN
6767 routines that no longer exist. Add with/use for new packages.
6768 * exp_cg.adb, sem_ch10.adb, sem_ch4.adb, sem_eval.adb,
6769 sem_prag.adb, sem_warn.adb: Change expanded names to refer to
6770 the new packages for things that moved. Add with/use for new
6772 * sem_ch3.adb: Likewise. Reinitialize vanishing fields.
6773 * exp_disp.adb: Likewise. Remove failing assertion.
6774 * sinfo.ads, einfo.ads: Remove code that is now generated into
6775 Sinfo.Nodes and Einfo.Entities.
6776 * sinfo.adb, einfo.adb: Replace bodies with "pragma No_Body;".
6777 We should delete these at some point, but No_Body makes make
6778 files easier. Some code is moved to Sinfo.Nodes, Einfo.Entities,
6779 Sinfo.Utils, and Einfo.Utils. Some is no longer necessary.
6780 * treepr.adb: Rewrite to use new tables. We no longer need
6782 * treepr.ads: Add comment.
6783 * types.ads: Move types Component_Alignment_Kind and
6784 Float_Rep_Kind here.
6785 * atree.h: Major update to match atree.ads changes. Add slot
6786 types, for use by getters/setters.
6787 * types.h: Move types Component_Alignment_Kind and
6788 Float_Rep_Kind here.
6789 * fe.h: Rewrite to deal with code that has changed or moved from
6790 Atree, Sinfo, Einfo.
6791 * nlists.h: Move some code to fe.h.
6792 * alloc.ads: Split Nodes_* constants into Node_Offsets and
6793 Slots, because Atree has two separate tables. Increase values.
6794 Remove Nodes_Release_Threshold. Improve comment.
6795 * debug.adb, gnat1drv.adb: Remove obsolete gnatd.A and gnatd.N
6796 switches. Add with/use for new packages.
6797 * opt.ads: Minor comment fix.
6798 * aspects.adb, checks.adb, comperr.adb, contracts.adb,
6799 cstand.adb, debug_a.adb, errout.adb, eval_fat.adb, exp_aggr.adb,

6820 sinput-l.adb, sprint.adb, style.adb, styleg.adb, tbuild.adb,
6821 tbuild.ads, uname.adb: Add with/use for new packages.
6822 * libgnat/a-stoubu.adb, libgnat/a-stouut.adb: Simplify to ease
6824 * libgnat/a-stobfi.adb, libgnat/a-stoufi.adb (Create_File,
6825 Create_New_File): Create file in binary format, to avoid
6826 introducing unwanted text conversions on Windows. Simplify to
6828 * libgnat/a-stteou__bootstrap.ads: New.
6829 * ceinfo.adb, csinfo.adb, nmake.adt, treeprs.adt, xeinfo.adb,
6830 xnmake.adb, xsinfo.adb, xtreeprs.adb: Delete.
6831 * Make-generated.in: Build and run the gen_il program to
6832 generate files. The files are generated in the ada/gen_il
6833 subdirectory, and then moved up to ada. We rely on gnatmake (as
6834 opposed to make) to build the gen_il program efficiently (i.e.
6835 don't do anything if the sources didn't change).
6836 * gcc-interface/Makefile.in (ADAFLAGS): Add -gnatU.
6837 (GNATMAKE_OBJS): Add new object files.

7369 hash function. For the other units, generate only the declaration.
7370 In all cases, set Lit_Hash to the entity of the function, if any.
7371 (Expand_Value_Attribute): Pass the 'Unrestricted_Access of Lit_Hash,
7372 if any, as third argument to the Value_Enumeration_NN function.

7586 Set_Raises_Constraint_Error on real division by zero just like
7587 it is called for integer division by zero earlier in this
7590 2021-05-05 Piotr Trojanek <trojanek@adacore.com>
7592 * freeze.adb (Build_Renamed_Body): Simplify IF and WHILE
7593 statements with the same condition.
7595 2021-05-05 Piotr Trojanek <trojanek@adacore.com>
7597 * pprint.adb (Expr_Name): Introduce local constants to make the
7598 code more readable and avoid repeated calls to Next to reach the
7599 ELSE part of an if-expression.
7601 2021-05-04 Piotr Trojanek <trojanek@adacore.com>
7603 * pprint.adb: Remove qualification of arbitrary calls to

7629 2021-05-04 Piotr Trojanek <trojanek@adacore.com>
7631 * lib-xref.adb (Generate_Reference_To_Formals): Remove dedicated
7632 branch for generic subprograms (they are now handled together
7633 with non-generic subprograms in the ELSE branch); replace a
7634 low-level Ekind membership test with a high-level call to
7635 Is_Access_Subprogram_Type.
7637 2021-05-04 Piotr Trojanek <trojanek@adacore.com>
7639 * sem_ch12.adb (Check_Abstract_Primitives): Match First_Formal
7641 * sem_ch6.adb (Is_Non_Overriding_Operation): Likewise.
7643 2021-05-04 Piotr Trojanek <trojanek@adacore.com>
7645 * sem_prag.adb (Collect_Global_Item): Iterate directly over
7648 2021-05-04 Piotr Trojanek <trojanek@adacore.com>
7650 * sem_prag.ads (Collect_Subprogram_Inputs_Outputs): Update
7651 comment; this routine is no longer used by GNATprove.
7652 * sem_prag.adb (Find_Role): The IN parameter is on output only
7653 when it belongs to non-function; also, the otherwise constant
7654 object can only be written by a non-function.
7655 (Collect_Global_Item): The IN parameter can only be written when
7656 it belongs to non-function; also, unnest this check to make it
7659 2021-05-04 Arnaud Charlet <charlet@adacore.com>
7661 * libgnat/s-assert.ads (Assert_Failure): Now a renaming of
7663 * libgnat/a-assert.ads (Assertion_Error): Now a first class
7664 citizen. Remove dependency on System.Assertions.

7674 2021-05-04 Yannick Moy <moy@adacore.com>
7676 * gnat1drv.adb (Adjust_Global_Switches): Force error marker in
7679 2021-05-04 Bob Duff <duff@adacore.com>
7681 * binde.adb: No need for ??? marks in Binde, because it is
7682 superseded by Bindo.
7683 * bindo-writers.adb (Write_Unit_Closure): Verified that -Ra
7685 * exp_ch4.adb, sinfo.ads (Expand_N_Type_Conversion): Rules for
7686 conversions passed to gigi are documented in sinfo.ads.
7687 (Expand_N_Unchecked_Type_Conversion): Comment is a duplicate of
7689 (Expand_N_In): Robert already added sufficient comments years
7690 after the ??? comment was inserted.
7691 (Expand_Membership_Minimize_Eliminate_Overflow): I don't see any
7692 reason why Stand should export Long_Long_Integer'Base -- it
7693 doesn't export any other base types.
7694 (Size_In_Storage_Elements): We are doing an allocator, so we
7695 don't care about sizes in bits.
7696 (Expand_N_Allocator): PolyORB isn't going to be significantly
7697 improved, so we're not going to mess with remote access to
7699 (Optimize_Return_Stmt): It's not important to optimize return
7700 statements in predicate functions -- there are many
7701 more-important optimizations we could do. Keep part of the
7702 comment without "???", to clarify why the "and then ...".
7703 (User_Defined_Primitive_Equality_Op): The optimization doesn't
7704 seem important enough.
7705 (Expand_N_Unchecked_Type_Conversion): Refactor to use
7706 Expand_N_Unchecked_Expression.
7707 (Make_Array_Comparison_Op): This seems like a case of "it it's
7708 not broken, don't fix it". Too much risk of causing bugs.
7709 * debug_a.adb: Remove ??? comments asking why Current_Error_Node
7710 is maintained unconditionally, and add a comment explaining why.
7711 * errout.adb: These kinds of minor bugs do indeed exist, but
7712 we're never going to get around to fixing them "properly", so we
7713 need this code for robustness.
7714 * gnatchop.adb (Read_File): Document when read can fail.
7715 * gnatdll.adb (Parse_Command_Line): Nobody is complaining about
7716 these arbitrary limits, so no need to use Table. Increase the
7717 limits just in case. It is clear from the names what they are
7719 * gnatlink.adb: Add needed comments.
7720 (Delete): An existing comment makes clear it's intentional, and
7721 it's been like that since 1996.
7722 (Process_Args): Improve comments.
7723 (Search_Library_Path): Refactoring to avoid deep nesting.
7724 * inline.adb (Build_Body_To_Inline): Probably won't get around
7725 to doing that optimization.
7726 (Is_Unit_Subprogram): No, this should not be moved to Sem_Aux,
7727 because it is too specialized to this context.
7728 (Do_Reset): No comment is needed here; it's clear from the
7729 comment on Reset_Dispatching_Calls. Do_Reset is an artificial
7730 subprogram; if we had proper iterators, it would just be an if
7731 statement in the loop.
7732 (Rewrite_Function_Call): Probably won't get around to doing that
7734 * layout.adb (Layout_Type): The gigi comment doesn't need to be
7735 a ??? comment, and it's been that way since 2000. The
7736 limitation to scalars will likely never be investigated, and
7737 it's been that way since 2009.
7738 * lib.adb (Check_Same_Extended_Unit): This doesn't look like
7739 something that needs fixing; it looks like a permanent
7741 * lib-load.adb (Change_Main_Unit_To_Spec): It is good enough in
7743 (Load_Unit): Nobody will ever get around to investigating the
7744 obscure PMES oddity, and the optimization is not worth the
7746 * live.adb: It's not worth documenting this. It is used only
7747 with a debug switch. Nobody who has done significant work on it
7748 is still around, so it would require substantial investigation.
7749 * mdll.ads: I see no reason for USE.
7750 * namet.ads: Routines are obsolete, but they're not going
7751 anywhere anytime soon (too much work, and surprisingly delicate
7752 because of dependences on global variables).
7754 * osint.adb: Improve comments.
7755 (Full_Lib_File_Name): Use Smart_Find_File.
7757 2021-05-04 Piotr Trojanek <trojanek@adacore.com>
7759 * exp_prag.adb, sem_prag.adb: Replace low-level Ekind membership
7760 tests with a high-level call to Is_Formal_Object.

7764 * cstand.adb, sprint.adb, switch-c.adb, xr_tabls.ads,
7765 xr_tabls.adb, xref_lib.adb: Address ??? comments.
7767 2021-05-04 Piotr Trojanek <trojanek@adacore.com>
7769 * sem_prag.adb (Analyze_Global_Item): Take subprogram kind into
7770 account when accepting or rejecting a constant of an
7771 access-to-variable type as a global Output/In_Out; do this check
7772 inside an ELSIF branch to avoid unnecessary evaluation of the
7773 subsequent condition.
7775 2021-05-04 Piotr Trojanek <trojanek@adacore.com>
7777 * sem_prag.adb (Role_Error, Usage_Error): Replace calls to
7778 Name_Find and Get_Name_String with a call to To_String.
7780 2021-05-04 Ed Schonberg <schonberg@adacore.com>
7782 * exp_aggr.adb (Build_Siz_Exp): new function, subsidiary of
7783 Expand_Container_Aggregate, to create an expression to be used
7784 in the dynamic allocation of a container with a single container
7785 element association.
7786 (Add_Range): Handle static bounds of ranges over enumerations.
7787 (Expand_Container_Aggregate): Add declaration for size
7788 expression when needed, and use it in container object
7789 declaration for container.
7791 2021-05-04 Arnaud Charlet <charlet@adacore.com>
