60 | |
61 * par-ch12.adb (P_Formal_Derived_Type_Definition): In Ada_2020 | |
62 the keyword WITH can indicate the start of aspect specifications | |
63 and not a private type extension. | |
64 * sem_ch12.adb (Analyze_Formal_Type): Indicate that it is a | |
65 first subtype. | |
66 (Instantiate_Type): New procedure | |
67 Check_Shared_Variable_Control_Aspects to verify matching rules | |
68 between formal and actual types. Note that an array type with | |
69 aspect Atomic_Components is considered compatible with an array | |
70 type whose component type is Atomic, even though the array types | |
71 do not carry the same aspect. | |
72 * sem_ch13.adb (Analyze_One_Aspect): Allow shared variable | |
73 control aspects to appear on formal types. | |
74 (Rep_Item_Too_Early): Exclude aspects on formal types. | |

99 | |
100 * layout.adb (Layout_Type): In the case of composite types, do | |
101 not copy the Esize onto the RM_Size if the latter is not set. | |
102 * gcc-interface/decl.c (gnat_to_gnu_entity) <E_Record_Type>: | |
103 Also cap the alignment if an Object_Size clause has been | |
104 specified. Pass VAR_DECL in the call to validate_size for the | |

121 | |
122 * sem_ch8.adb (Note_Redundant_Use): It was already checking for | |

146 | |
147 * sem_ch13.adb (Analyze_Attribute_Definition_Clause): Set only | |

174 2019-12-16 Ed Schonberg <schonberg@adacore.com> | |
175 | |
176 * sem_ch4.adb (Try_Container_Indexing): In the case of a derived | |
177 container type, use the base type to look for candidate indexing | |
178 operations, because the object may be a constrained subtype or | |
179 itype with no explicit declaration. Candidate indexing | |
180 operations are found in the same scope and list of declarations | |
181 as the declaration of the base type. | |
182 | |
183 2019-12-16 Ed Schonberg <schonberg@adacore.com> | |
184 | |

194 aggregates, to designate an Ada2020 array or container aggregate | |
195 that is bracket-delimited in the source. | |
196 * sem_attr.adb (Analyze_Attribute): For attribute Reduce, verify | |
197 that two arguments are present, and verify that the prefix is a | |
198 stream or an object that is iterable (array or contrainer). | |
199 (Resolve_Attribute): For attribute Reduce, resolve initial value | |
200 with the type of the context. Type-checking of element type of | |
201 prefix is performed after expansion. | |
202 * exp_attr.adb (Expand_N_Attribute_Reference): For attribute | |
203 Reduce, expand into a loop: a) If prefix is an aggregate with a | |
204 single iterated component association, use its iterator | |
205 specification to construct a loop, b) If prefix is a name, build | |
206 a loop using an element iterator loop. | |
207 * scans.ads: Add brackets tokens. | |
208 | |

215 (components_need_strict_alignment): Remove test on Is_Aliased and | |
216 add test for the independence of the component. | |
217 (validate_size): Add S1 and S2 string parameters and use them to | |
218 give better error messages for fields. Tweak a couple of messages. | |
219 * einfo.ads (Has_Independent_Components): Document more cases. | |
220 (Is_Independent): Likewise. | |
221 (Strict_Alignment): Document new semantics. | |
222 * exp_ch9.adb (Install_Private_Data_Declarations): Also set the | |
223 Is_Independent flag along with Is_Aliased on the renaming | |
224 entity. | |
225 * freeze.adb (Size_Known): Remove always-false test and add test | |
226 for the strict-alignment on the record type. Remove redundant | |
227 tests and add test for the strict-alignment on the component | |
228 type. | |
229 (Check_Strict_Alignment): Set the flag if the type is by-ref and | |
230 remove now redundant conditions. Set the flag on an array type | |
231 if it has aliased components. In the record type case, do not | |
232 set type for C_Pass_By_Copy convention. | |
233 (Freeze_Array_Type): Move code checking for conflicts between | |
234 representation aspects and clauses to before specific handling | |
235 of packed array types. Give a warnind instead of an error for a | |
236 conflict with pragma Pack. Do not test Has_Pragma_Pack for the | |
237 specific handling of packed array types. | |
238 (Freeze_Record_Type): Move error checking of representation | |
239 clause to... | |
240 (Freeze_Entity): ...here after Check_Strict_Alignment is called. | |

242 flag along with Is_Aliased on the Itype. | |
243 * sem_ch13.adb (Check_Record_Representation_Clause): Do not set | |
244 the RM size for a strict-alignment type. | |
245 * sem_ch3.adb (Add_Interface_Tag_Components): Also set the | |
246 Is_Independent flag along with Is_Aliased on the tag. | |
247 (Add_Interface_Tag_Components): Likewise on the offset. | |
248 (Analyze_Component_Declaration): Likewise on the component. | |
249 (Analyze_Object_Declaration): Likewise on the object. | |

264 | |
265 2019-12-16 Eric Botcazou <ebotcazou@adacore.com> | |
266 | |
267 * sem_ch8.adb (Analyze_Object_Renaming): Set Atomic, Independent | |
268 and Volatile_Full_Access aspects on the entity of the renaming | |
269 the same way as the Volatile aspect is set. | |
270 * sem_util.ads (Is_Atomic_Object_Entity): Move declaration to... | |
271 (Is_Independent_Object): New function. | |
272 (Is_Volatile_Full_Access_Object): Likewise. | |
273 * sem_util.adb (Is_Atomic_Object_Entity): ...here. | |
274 (Prefix_Has_Atomic_Components): Minor tweak. | |
275 (Is_Atomic_Object): Test Is_Atomic on the Etype uniformly. | |
276 (Is_Atomic_Or_VFA_Object): Call Is_Volatile_Full_Access_Object. | |
277 (Is_Independent_Object): New predicate. | |

296 SIS_Aspect_Import_Seen to True when appropriate. | |
297 * par-ch10.adb, par-ch12.adb, par-ch2.adb, par-ch3.adb, | |
298 par-ch5.adb, par-ch7.adb, par-ch9.adb, par-endh.adb, | |
299 par-util.adb: Call Scopes. | |
300 | |

302 | |
303 * sem_prag.adb (Atomic_Components): Remove local variable and | |
304 fix consistency issues. Call Component_Type on the Etype of E. | |
305 (Independent_Components): Remove local variable. | |

318 (simple_atomic_access_required_p): New predicate. | |
319 (Call_to_gnu): Remove outer_atomic_access parameter and change the | |
320 type of atomic_access parameter to atomic_acces_t. Replace call to | |
321 atomic_access_required_p with simple_atomic_access_required_p for | |
322 the in direction and call get_atomic_access for the out direction | |
323 instead of [outer_]atomic_access_required_p. | |
324 (lhs_or_actual_p): Constify local variables. | |
325 (present_in_lhs_or_actual_p): Likewise. | |
326 (gnat_to_gnu) <N_Identifier>: Replace call to atomic_access_required_p | |

328 <N_Explicit_Dereference>: Likewise. | |
329 <N_Indexed_Component>: Likewise. | |
330 <N_Selected_Component>: Likewise. | |

335 | |
336 2019-12-16 Eric Botcazou <ebotcazou@adacore.com> | |

342 (Exception_Mechanism_Type): Likewise. | |
343 | |
344 2019-12-16 Gary Dismukes <dismukes@adacore.com> | |
345 | |
346 * checks.adb, sem_util.adb: Minor reformatting and U.S. spelling | |
347 adjustment. | |
348 | |
349 2019-12-16 Bob Duff <duff@adacore.com> | |
350 | |
351 * sem_ch10.adb (Analyze_Subunit): Give an error if the subunit | |
352 is not a proper body. This hides the confusing "duplicate body" | |
353 message that was previously given. | |
354 | |
355 2019-12-16 Eric Botcazou <ebotcazou@adacore.com> | |
356 | |
357 * exp_ch8.adb (Expand_N_Object_Renaming_Declaration): Document | |
358 third special case of renamings requiring special handling. | |
359 (Evaluation_Required): Return true for an atomic or VFA prefix. | |
360 | |
361 2019-12-16 Ed Schonberg <schonberg@adacore.com> | |
362 | |
363 * checks.adb (Apply_Float_Conversion_Check): Use node of type | |
364 conversion and not its parent, when inserting the declaration | |
365 for the temporary that hold the result of the conversion. | |
366 Previously the declaration was inserted above the parent of the | |
367 conversion, apparently as a small optimization for the | |
368 subsequent traversal in Insert_Actions. Unfortunately a similar | |
369 optimization takes place in Insert_Actions, assuming that the | |
370 insertion point must be above the expression that creates the | |
371 actions to insert. This is not correct in the presence of | |
372 conditional expressions (i.e. since Ada2012), where the | |
373 insertion must be in the list of actions attached to the current | |
374 alternative. | |
375 | |
376 2019-12-16 Bob Duff <duff@adacore.com> | |
377 | |
378 * sem_attr.adb (Analyze_Attribute): Use Known_RM_Size. But we | |
379 still need Size_Known_At_Compile_Time, because when the size | |
380 really is known, sometimes only one or the other of these is | |
381 True. | |
382 | |
383 2019-12-16 Eric Botcazou <ebotcazou@adacore.com> | |
384 | |
385 * sem_util.adb (Is_Atomic_Or_VFA_Object): Also return true for | |
386 components whose type is Volatile_Full_Access or which are | |
387 subject to the aspect/pragma individually. | |
388 * sem_util.ads (Is_Atomic_Object_Entity): Small comment fix. | |
389 | |
390 2019-12-16 Yannick Moy <moy@adacore.com> | |
391 | |
392 * exp_ch6.adb: Fix comment. | |
393 * sem_res.adb (Resolve_Call): Do not check No_Recursion | |
394 restriction or indirectly No_Secondary_Stack restriction, when | |
395 inside an ignored ghost subprogram. | |
396 | |
397 2019-12-16 Arnaud Charlet <charlet@adacore.com> | |
398 | |
399 * impunit.adb: Add a-nbnbin, a-nbnbre, a-nubinu to Ada 2020 | |
400 units. | |
401 * Makefile.rtl: Enable new file. | |
402 * libgnat/a-nbnbin.adb, libgnat/a-nbnbin.ads, | |
403 libgnat/a-nbnbre.adb, libgnat/a-nbnbre.ads, | |
404 libgnat/a-nubinu.ads: New files. Provide default standalone | |
405 implementation of Ada.Numerics.Big_Numbers.Big_* based on | |
406 System.Generic_Bignum. | |
407 * libgnat/a-nbnbin__gmp.adb: Alternate implementation of | |
408 Ada.Numerics.Big_Numbers.Big_Integers based on GMP. Not enabled | |

432 | |
433 2019-12-16 Eric Botcazou <ebotcazou@adacore.com> | |
434 | |
435 * exp_ch6.adb (Requires_Atomic_Or_Volatile_Copy): New predicate. | |

457 (Freeze_Entity): ...here instead. | |
458 * sem_ch12.adb (Instantiate_Object): Improve wording of errors | |
459 given for legality rules in C.6(12) and implement the new rule | |
460 in C.6(13). | |
461 * sem_res.adb (Resolve_Actuals): Likewise. | |

493 2019-12-13 Javier Miranda <miranda@adacore.com> | |
494 | |
495 * sem_ch13.adb (Analyze_Aspect_Specification): Processing a | |
496 precondition, if the expression is of the form A and then B, do | |
497 not generate separate Pre/Post aspects for the separate clases | |
498 when we are processing a generic unit. Required to avoid | |
499 reporting spurious visibility errors on the instantiations. | |
500 | |
501 2019-12-13 Eric Botcazou <ebotcazou@adacore.com> | |
502 | |

508 | |
509 * sem_util.ads (Is_Atomic_Object): Mention relevant RM clauses. | |
510 * sem_util.adb (Is_Atomic_Object): For an indexed component, | |
511 only look at the Has_Atomic_Components aspect of the prefix and | |
512 do not recurse on it; for a selected component, do not look at | |
513 the prefix. | |
514 (Is_Atomic_Or_VFA_Object): Minor tweak. | |
515 | |
516 2019-12-13 Arnaud Charlet <charlet@adacore.com> | |
517 | |
518 * libgnat/a-calfor.ads, libgnat/a-calfor.adb (Split_Duration): | |

526 | |
527 2019-12-13 Javier Miranda <miranda@adacore.com> | |
528 | |
529 * sem_prag.adb (Analyze_Pragma): Propagate the | |
530 Linker_Section_Attribute to the ultimate alias of the subprogram | |
531 to facilitate the C backend processing this attribute. | |
532 | |
533 2019-12-13 Yannick Moy <moy@adacore.com> | |
534 | |
535 * sem_util.adb (Original_Aspect_Pragma_Name): Go through | |

543 | |
544 * sem_res.adb (Resolve, Valid_Conversion): Add Base_Type call | |
545 when testing whether a type is a general access type. | |
546 | |
547 2019-12-13 Javier Miranda <miranda@adacore.com> | |
548 | |
549 * exp_ch4.adb (Expand_N_Unchecked_Type_Conversion): Generate an | |
550 extra temporary for cases unsupported by the C backend. | |
551 | |
552 2019-12-13 Steve Baird <baird@adacore.com> | |
553 | |
554 * einfo.ads: Correct comment for Derived_Type_Link to reflect | |
555 that fact that this function is now used for more than just | |
556 generation of warnings. | |
557 * sem_ch3.adb (Build_Derived_Type): Do not call | |
558 Set_Derived_Type_Link if the derived type and the parent type | |
559 are in different compilation units. Such a derivation cannot be | |
560 a problematic "early" derivation (identifying these is what the | |
561 Derived_Type_Link attribute is used for) and we don't like | |
562 inter-unit references that go in the opposite direction of | |
563 semantic dependencies. | |
564 * sem_ch13.adb (Is_Type_Related_Rep_Item): A new function, | |
565 analogous to the existing function Is_Operational_Item. | |
566 (Rep_Item_Too_Late): Generate a hard error (with same text as | |
567 the warning that was previously being generated) if the | |
568 AI12-0109 legality rule is violated. | |

576 2019-12-13 Gary Dismukes <dismukes@adacore.com> | |
577 | |
578 * exp_attr.adb (Expand_N_Attribute_Reference, | |
579 Attribute_Address): Suppress generation of a call to | |
580 Base_Address in the case where the Address attribute is being | |
581 used to initialize a corresponding component of an activation | |
582 record. | |
583 (Is_Unnested_Component_Init): New function to determine whether | |
584 an attribute reference for Address is used to initialized a | |
585 component of an activation record object that corresponds to the | |
586 object denoted by the prefix of the attribute (an assignment | |
587 used in support of unnesting for back ends like LLVM). | |
588 | |
589 2019-12-13 Ed Schonberg <schonberg@adacore.com> | |
590 | |
591 * sem_res.adb (Resolve): IF an entity reference is overloaded | |
592 because its type has an Implicit_Dereference aspect, we must | |
593 examine the discriminants of the type to determine whether an | |
594 explicit dereference must be inserted for use in code | |
595 generation. Previously this was done for other expressions but | |
596 not for entity references by themselves. This was sufficient to | |
597 handle uses of the aspect in container handling and iteration, | |
598 but not more generally. | |
599 | |
600 2019-12-13 Javier Miranda <miranda@adacore.com> | |
601 | |
602 * exp_disp.ads (Expand_Interface_Thunk): Adding one formal (the | |
603 interface type). | |
604 * exp_disp.adb (Expand_Interface_Thunk): Using the added formal | |
605 to ensure the correct profile of the thunk generated for | |
606 predefined primitives; in addition, the added formal is also | |
607 used to perform a check that ensures that the controlling type | |
608 of the thunk is the one expected by the GCC backend. | |
609 (Make_Secondary_DT, Register_Primitive): Adding the new formal | |
610 to the calls to Expand_Interface_Thunk. | |
611 * exp_ch6.adb (Register_Predefined_DT_Entry): Adding the new | |
612 formal to the call to Expand_Interface_Thunk. | |
613 * exp_intr.adb (Expand_Unc_Deallocation): When deallocating a | |
614 controlled type and the call to unchecked deallocation is | |
615 performed with a pointer to one of the convered interface types, | |
616 displace the pointer to the object to reference the base of the | |
617 object to deallocate its memory. | |
618 * gcc-interface/trans.c (maybe_make_gnu_thunk): Assert that the | |
619 controlling type of the thunk is an interface type. | |
620 | |
621 2019-12-13 Bob Duff <duff@adacore.com> | |
622 | |
623 * exp_attr.adb (Is_Available): Remove this function, and replace | |
624 all calls with RTE_Available. RTE_Available will return True if | |
625 "not Configurable_Run_Time_Mode". Remove the "???" comment. | |
626 | |
627 2019-12-13 Ed Schonberg <schonberg@adacore.com> | |
628 | |
629 * sem_ch7.adb (Analyze_Package_Body_Helper): Do not call | |
630 Declare_Inherited_Private_Subprograms on s child body: the | |
631 required operations have already been created when analyzing the | |
632 corresponding package declaration. This prevents a redeclaration | |
633 of inehrited operation, and a crash when inserting the new | |
634 operation in the current scope. | |
635 | |
636 2019-12-13 Yannick Moy <moy@adacore.com> | |
637 | |
638 * sem_prag.adb (Analyze_Depends_In_Decl_Part, | |
639 Analyze_Global_In_Decl_Part, | |
640 Analyze_Refined_Depends_In_Decl_Part, | |
641 Analyze_Refined_Global_In_Decl_Part, Check_Missing_Part_Of): | |
642 Skip redundant checking involving visibility inside | |
643 instantiations. | |
644 | |
645 2019-12-13 Yannick Moy <moy@adacore.com> | |
646 | |
647 * sem_res.adb (Resolve_Call): Prevent inlining inside while loop | |
648 conditions. | |
649 * sem_util.adb, sem_util.ads (In_While_Loop_Condition): New | |
650 query function. | |
651 | |
652 2019-12-13 Bob Duff <duff@adacore.com> | |
653 | |
654 * impunit.ads: Add Ada_202X_Unit. | |
655 * impunit.adb: Add a table Non_Imp_File_Names_2X analogous to | |
656 the other tables. Add code to search this table. | |
657 * opt.ads: Add Warn_On_Ada_202X_Compatibility flag, currently | |
658 always True. | |
659 * sem_ch10.adb (Analyze_With_Clause): Give a warning if an Ada | |
660 2020 unit is with-ed when Ada_Version < Ada_2020. Change 'if' | |
661 to 'case': Full coverage rules rule. | |
662 | |
663 2019-12-13 Bob Duff <duff@adacore.com> | |
664 | |
665 * rtsfind.ads: Minor comment fix. | |
666 | |
667 2019-12-13 Gary Dismukes <dismukes@adacore.com> | |
668 | |
669 * sem_util.adb (Scope_Within): For the case of checking for a | |
670 task type procedure, check the Implementation_Base_Type of Curr. | |
671 (Scope_Within_Or_Same): For the case of checking for a task type | |
672 procedure, check the Implementation_Base_Type of Curr. | |
673 | |
674 2019-12-13 Arnaud Charlet <charlet@adacore.com> | |
675 | |
676 * impunit.adb (Non_Imp_File_Names_12): Add | |
677 Ada.Containers.Vectors.Generic_Parallel_Sorting. | |
678 | |
679 2019-12-13 Justin Squirek <squirek@adacore.com> | |
680 | |
681 * sem_res.adb (Resolve_Allocator): Add calls to | |
682 Check_Cond_Expr_Accessibility when a conditional expression is | |
683 found. | |
684 (Check_Allocator_Discrim_Accessibility_Exprs): Created to | |
685 recursively traverse a potentially compound conditional | |
686 expression and perform accessibility checks for each | |
687 alternative. | |
688 * sem_util.adb (Dynamic_Accessibility_Level): Avoid use of | |
689 original node of the expression in question so we can handle | |
690 dynamic accessibility in the limited case of a constant folded | |
691 conditional expression. | |
692 | |
693 2019-12-13 Steve Baird <baird@adacore.com> | |
694 | |
695 * exp_ch4.adb (Expand_N_Op_Eq.Is_Equality): Move this function | |
696 from within Expand_N_Op_Eq.Find_Equality out to immediately | |
697 within Expand_N_Op_Eq in order to give it greater visibility. | |
698 Add a new Typ parameter (defaulted to Empty) which, if | |
699 non-empty, means the function will return False in the case of | |
700 an equality op for some other type. | |
701 * (Expand_N_Op_Eq.User_Defined_Primitive_Equality_Op): A new | |
702 function. Given an untagged record type, finds the corresponding | |
703 user-defined primitive equality op (if any). May return Empty. | |
704 Ignores visibility. | |
705 * (Expand_N_Op): For Ada2012 or later, check for presence of a | |
706 user-defined primitive equality op before falling back on the | |
707 usual predefined component-by-component comparison. If found, | |
708 then call the user-defined op instead. | |
709 | |
710 2019-12-13 Justin Squirek <squirek@adacore.com> | |
711 | |
712 * sem_ch6.adb (Check_Overriding_Indicator): Modify condition to | |
713 take into account the modification of the Is_Hidden flag within | |
714 generic instances. | |
715 (Verify_Overriding_Indicator): Add an exception for controlled | |
716 primitives within an instance. | |
717 | |
718 2019-12-13 Ed Schonberg <schonberg@adacore.com> | |
719 | |
720 * sinfo.ads, sinfo.adb (Aspect_On_Partial_View, | |
721 Set_Aspect_On_Partial_View): New flag for use by SPARK, to | |
722 indicate whether an aspect that appears on a type declaration | |
723 applies to the partial view of that type. | |
724 * sem_ch13.adb (Analyze_Aspect_Specification): Set new flag | |
725 appropriately. | |
726 | |
727 2019-12-12 Ed Schonberg <schonberg@adacore.com> | |
728 | |
729 * sem_ch13.adb (Same_Reprewentation): if the actual in a call is | |
730 a generic actual type, use its bsae type to determine whether a | |
731 change of representastion may be necessary for proper parameter | |
732 passing. | |
733 | |
734 2019-12-12 Ed Schonberg <schonberg@adacore.com> | |
735 | |
736 * sem_type.adb (Find_Unique_Type): A call to the universal | |
737 access equality operator requires one operand to be a universal | |
738 access, and the other to be an access type. There is no | |
739 requirement, as previously implied by this routine, that | |
740 pool-specific access types were illegal in this context. | |
741 | |
742 2019-12-12 Steve Baird <baird@adacore.com> | |
743 | |
744 * sem_ch6.adb | |
745 (New_Overloaded_Entity.Check_Conforming_Paramters): Add new | |
746 Conformance_Type parameter. With the value of | |
747 Subtype_Conformant, the behavior of Check_Conforming_Parameters | |
748 is unchanged. The call in Matching_Entry_Or_Subprogram to | |
749 instead passes in Type_Conformant. This corresponds to the use | |
750 of "type conformant" in Ada RM 9.4(11.4/3). | |
751 (New_Overloaded_Entity.Has_Matching_Entry_Or_Subprogram): Add | |
752 new Normalized_First_Parameter_Type function to help in ignoring | |
753 the distinction between protected and access-to-protected first | |
754 parameters when checking prefixed-view profile matching. Replace | |
755 computations of the type of the first parameter with calls to | |
756 this function as appropriate. | |
757 | |
758 2019-12-12 Ed Schonberg <schonberg@adacore.com> | |
759 | |
760 * sem_ch5.adb: (Analyze_Iterator_Specification): If the | |
761 iteration is over a slice, complete the resolution of its | |
762 bounds, which may be aebitrary expressions. The previous | |
763 pre-analysis may have created itypes for the slice but has not | |
764 performed the expansion that for example may introduce actions | |
765 that specify explicit dereferences and run-time checks. | |
766 | |
767 2019-12-12 Ed Schonberg <schonberg@adacore.com> | |
768 | |
769 * sem_ch8.adb: Improve error message for dispatching subprogram | |
770 formals. | |

777 2019-12-12 Steve Baird <baird@adacore.com> | |
778 | |
779 * sem_ch10.adb (Install_With_Clause): Check for the case of a | |
780 circular dependency involving a predefined (or GNAT-defined) | |
781 unit and handle that case by generating an appropropriate error | |
782 message. | |
783 | |
784 2019-12-12 Gary Dismukes <dismukes@adacore.com> | |

1409 * sem_ch7.adb (Install_Parent_Private_Declarations): If a | |
1410 generic child unit is instantiated within a sibling child unit, | |
1411 the analysis of its private part requires that the private part | |
1412 of the ancestor be available, as is done when the context | |

1465 Get_Homonym_Number. | |
1466 * exp_util.ads, exp_util.adb (Homonym_Number): Mirror style of | |
1467 the removed Get_Homonym_Number routine, i.e. initialize local | |
1468 objects at declaration and refine the type of result. | |
1469 * sem_util.adb (Add_Homonym_Suffix): Use Homonym_Number instead | |
1470 of Get_Homonym_Number. | |

1513 | |
1514 * xref_lib.adb (Get_Symbol_Name): If we reach EOF in the first | |
1515 loop without finding the symbol, return "???". Otherwise, it's | |
1516 an infinite loop. | |
1517 (Parse_EOL): Assert that we're not already at EOF. Remove | |
1518 processing of LF/CR -- there are no operating systems that use | |
1519 that. | |
1520 | |
1521 2019-09-19 Eric Botcazou <ebotcazou@adacore.com> | |
1522 | |

1532 | |
1533 * exp_ch5.adb (Expand_Assign_Array_Loop_Or_Bitfield): Move call | |
1534 to RTE_Available later, so it doesn't disturb the elab order. | |
1535 The RE_Copy_Bitfield entity is defined in package | |
1536 System.Bitfields which has a dependency on package | |
1537 System.Bitfield_Utils, which has it its spec: | |
1538 pragma Elaborate_Body; | |
1539 The query on RTE_Available forces loading and analyzing | |

1548 clause is of the form X'Address and the alignment of X is | |
1549 compatible. | |

1551 2019-09-18 Ed Schonberg <schonberg@adacore.com> | |
1552 | |
1553 * sem_res.adb (Set_Mixed_Node_Expression): If a conditional | |
1554 expression has universal_real alternaitves and the context is | |
1555 Universal_Fixed, as when it is an operand in a fixed-point | |
1556 multiplication or division, resolve the expression with a | |
1557 visible fixed-point type, which must be unique. | |
1558 | |
1559 2019-09-18 Ed Schonberg <schonberg@adacore.com> | |
1560 | |
1561 * sem_ch3.adb (Constrain_Component_Type): For a discriminated | |
1562 type, handle the case of a constraint given by a conversion of a | |
1563 discriminant of the enclosing type. Necessary when compiling a | |
1564 discriminated task for a restricted run-time, when the generated | |
1565 Secondary_Stack component may be set by means of an aspect on | |
1566 the task type. | |
1567 | |
1568 2019-09-18 Ed Schonberg <schonberg@adacore.com> | |
1569 | |
1570 * exp_aggr.adb (Expand_Record_Aggregate, Rewrite_Discriminant): | |
1571 After rewriting a reference to an outer discriminant as a | |
1572 selected component of the enclosing object, analyze the selected | |
1573 component to ensure that the entity of the selector name is | |
1574 properly set. This is necessary when the aggregate appears | |
1575 within an expression that may have been analyzed already. | |
1576 | |
1577 2019-09-18 Justin Squirek <squirek@adacore.com> | |

1584 | |
1585 * exp_ch4.adb (Expand_N_Type_Conversion): Add calculation of an | |
1586 alternative operand for the purposes of generating accessibility | |
1587 checks. | |
1588 | |

1590 | |
1591 * exp_aggr.adb (Build_Array_Aggr_Code): In STEP 1 (c), duplicate | |
1592 the expression and reset the Loop_Actions for each loop | |
1593 generated for an others choice. | |
1594 | |
1595 2019-09-18 Justin Squirek <squirek@adacore.com> | |
1596 | |
1597 * einfo.adb, einfo.ads (Minimum_Accessibility): Added new field. | |
1598 (Set_Minimum_Accessibility): Added to set new field. | |
1599 (Minimum_Accessibility): Added to fetch new field. | |
1600 * exp_ch6.adb (Expand_Subprogram_Call): Modify calls to fetch | |
1601 accessibility levels to the new subprogram Get_Accessibility | |
1602 which handles cases where minimum accessibility might be needed. | |
1603 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Add section to | |
1604 generate a Minimum_Accessibility object within relevant | |
1605 subprograms. | |
1606 * sem_util.adb, sem_util.ads (Dynamic_Accessibility_Level): | |
1607 Additional documentation added and modify section to use new | |
1608 function Get_Accessibility. | |
1609 (Get_Accessibility): Added to centralize processing of | |
1610 accessibility levels. | |
1611 | |
1612 2019-09-18 Steve Baird <baird@adacore.com> | |
1613 | |
1614 * sem_util.ads (Interval_Lists): A new visible package. This | |
1615 package is visible because it is also intended for eventual use | |
1616 in Sem_Eval.Subtypes_Statically_Compatible when that function is | |
1617 someday upgraded to handle static predicates correctly. This | |
1618 new package doesn't really need to be visible for now, but it | |
1619 still seems like a good idea. | |
1620 * sem_util.adb (Gather_Components): Implement AI12-0086 via the | |
1621 following strategy. The existing code knows how to take a static | |
1622 discriminant value and identify the corresponding variant; in | |
1623 the newly-permitted case of a non-static value of a static | |
1624 subtype, we arbitrarily select a value of the subtype and find | |
1625 the corresponding variant using the existing code. Subsequently, | |
1626 we check that every other value of the discriminant's subtype | |
1627 corresponds to the same variant; this is done using the newly | |
1628 introduced Interval_Lists package. | |
1629 (Interval_Lists): Provide a body for the new package. | |
1630 | |
1631 2019-09-18 Javier Miranda <miranda@adacore.com> | |
1632 | |
1633 * exp_ch4.adb (Expand_N_Op_Eq): The frontend assumes that we can | |
1634 do a bit-for-bit comparison of two access to protected | |
1635 subprogram pointers. However, there are two reasons why we may | |
1636 not be able to do that: (1) there may be padding bits for | |
1637 alignment before the access to subprogram, and (2) the access to | |
1638 subprogram itself may not be compared bit-for- bit because the | |
1639 activation record part is undefined: two pointers are equal iff | |
1640 the subprogram addresses are equal. This patch fixes it by | |
1641 forcing a field-by-field comparison. | |
1642 * bindgen.adb (Gen_Adainit): The type No_Param_Proc is defined | |
1643 in the library as having Favor_Top_Level, but when we create an | |
1644 object of that type in the binder file we don't have that | |
1645 pragma, so the types are different. This patch fixes this issue. | |
1646 * libgnarl/s-interr.adb, libgnarl/s-interr__hwint.adb, | |
1647 libgnarl/s-interr__sigaction.adb, libgnarl/s-interr__vxworks.adb | |
1648 (Is_Registered): This routine erroneously assumes that the | |
1649 access to protected subprogram is two addresses. We need to | |
1650 create the same record that the compiler makes to ensure that | |
1651 any padding is the same. Then we have to look at just the first | |
1652 word of the access to subprogram. This patch fixes this issue. | |

2266 | |
2267 * exp_ch6.adb (Needs_BIP_Alloc_Form): Call | |
2268 Requires_Transient_Scope rather than checking constrainedness | |
2269 and so forth. We have previously improved | |
2270 Requires_Transient_Scope to return False in various cases, | |
2271 notably a limited record with an access discriminant. This | |
2272 change takes advantage of that to avoid using the secondary | |
2273 stack for functions returning such types. | |
2274 (Make_Build_In_Place_Call_In_Allocator): Be consistent by | |
2275 calling Needs_BIP_Alloc_Form rather than Is_Constrained and so | |
2276 forth. | |
2277 * sem_ch4.adb (Analyze_Allocator): The above change causes the | |
2278 compiler to generate code that is not legal Ada, in particular | |
2279 an uninitialized allocator for indefinite subtype. This is | |
2280 harmless, so we suppress the error message in this case. | |

2311 that may be generated in that expansion must carry the scope of | |

2318 occurrs in the same declarative part as the ancestor subprogram | |
2319 being called, the`expression for the precondition has not been | |
2320 analyzed yet. Such a call may appear, e.g. in an expression | |
2321 function. In that case, the replacement of formals by actuals in | |
2322 the call cannot use the formal entities of the subprogram being | |
2323 called, and the occurrence of the formals in the expression must | |
2324 be located by name (Chars fields) as would be done at a later | |
2325 freeze point, when the expression is resolved in the context of | |

2333 initialization is not allowed for these variables. Other | |

2340 the expression Exp rather than the Expression of the | |
2341 Original_Node, in the case where Exp has been rewritten; | |
2342 otherwise, when Original_Node is the same as Exp, apply the | |
2343 recursive call to the Expression. | |
2344 (Check_Initialization): Revise condition for special check on | |
2345 type conversions of limited function calls to test Original_Node | |
2346 (avoiding spurious errors on expanded unchecked conversions | |
2347 applied to build-in-place dispatching calls). | |

2387 * sem_ch13.adb (Is_Null_Array): New function, used to detect the | |
2388 null array case; used to warn about uncheckedly converting to a | |
2389 zero-sized array. It is unfortunate that we can't just check | |
2390 the size, and warn on all cases of converting from a | |
2391 nonzero-sized type to a zero-sized one. That's because "0" means | |
2392 two different things: "size is zero" and "size is unknown". | |
2393 Until we fix that design flaw, we need this more targeted fix. | |

2851 invoke Add_Inlined_Instance. Also deal with the case where the | |
2852 call itself is within an instance. | |

2854 (Add_Inlined_Subprogram): Remove conditions always fulfilled. | |
2855 (Add_Pending_Instantiation): Move the defence against ludicruous | |

2901 back end use the same Sloc as pragmas processed earlier, in the | |

3670 libgnat/s-valrea.ads, libgnat/s-valuns.ads, | |
3671 libgnat/s-valwch.ads: Change categorization of packages that | |
3672 implement attribute 'Value from Pure to Preelaborate, to prevent | |
3673 undesirable optimizations when the evaluation of the attribute | |
3674 raises Constraint_Error, but subsequent use of the result of | |
3675 this evsaluation is removed by a subsequent optimization. | |
3676 | |

3696 have as many components as the length of the names string. As a | |
3697 result of this enhancement, the internal tables declared using | |
3698 Index_Table have a length closer to the real needs, thus | |
3699 avoiding the declaration of large arrays on 32-bit CCG targets. | |

3870 types which are not visibly deep. | |
3871 - Component_Is_Visible_In_SPARK is used to avoid doing pointer | |
3872 aliasing checks on components which are not visible in SPARK. | |

3874 analysis. Error messages for failed aliasing checks are only | |
3875 output in this case. | |
3876 Additionally, errors on constructs not supported in SPARK are | |
3877 removed as duplicates of marking errors. Components are stored | |
