6 | ||
7 | * gcc-interface/trans.c (Pragma_to_gnu) <Pragma_Warnings>: Push a | |
8 | diagnostics state for pragma Warnings (Off) before turning off all | |
9 | the warnings and only pop it for pragma Warnings (On). | |
10 | ||

27 | ||
28 | * libgnat/s-atopar.ads, libgnat/s-atopex.ads (Atomic_Type): Can | |
29 | now be marked Atomic. This requires marking the unit Ada 202x. | |
30 | ||

49 | ||
50 | 2019-12-18 Gary Dismukes <dismukes@adacore.com> | |
51 | ||
52 | * sem_res.adb (Resolve_Type_Conversion): Add handling for access | |
53 | types with designated operand and target types that are | |
54 | referenced in places that have a limited view of an interface | |
55 | type by retrieving the nonlimited view when it exists. Add ??? | |
56 | comments related to missing limited_with_clause handling for | |
57 | Target (in the non-access case). | |
58 | ||
59 | 2019-12-18 Ed Schonberg <schonberg@adacore.com> | |
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. | |
75 | * sem_prag.adb (Mark_Type): Handle properly pragmas that come | |
76 | from aspects on formal types. | |
77 | (Analyze_Pragma, case Atomic_Components): Handle formal types. | |

97 | ||
98 | 2019-12-18 Eric Botcazou <ebotcazou@adacore.com> | |
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 | |
105 | Esize of a type. | |
106 | (validate_size): Be prepared to give an error on an Object_Size | |
107 | clause. | |
108 | ||
109 | 2019-12-18 Eric Botcazou <ebotcazou@adacore.com> | |
110 | ||

116 | ||
117 | * sem_ch3.adb (Derive_Subprogram): Do not set the | |
118 | Requires_Overriding flag in the above-mentioned case. | |
119 | ||
120 | 2019-12-18 Bob Duff <duff@adacore.com> | |
121 | ||
122 | * sem_ch8.adb (Note_Redundant_Use): It was already checking for | |
123 | a use clause in the visible part of the child. Add an additional | |
124 | check for a use clause in the context clause of the child. | |
125 | ||
126 | 2019-12-16 Bob Duff <duff@adacore.com> | |
127 | ||
128 | * errout.adb (Handle_Serious_Error): Disable the above-mentioned | |
129 | warnings. | |

140 | ||
141 | * errout.ads, errout.adb (Is_Size_Too_Small_Message): Check for | |
142 | "size for" instead of "size for& too small, minimum allowed is | |
143 | ^". | |
144 | ||
145 | 2019-12-16 Eric Botcazou <ebotcazou@adacore.com> | |

147 | * sem_ch13.adb (Analyze_Attribute_Definition_Clause): Set only | |
148 | the RM_Size on the subtype built for a Component_Size clause | |
149 | when the component type is a biased integer type. | |
150 | ||
151 | 2019-12-16 Arnaud Charlet <charlet@adacore.com> | |

168 | ||
169 | 2019-12-16 Eric Botcazou <ebotcazou@adacore.com> | |
170 | ||
171 | * freeze.adb (Check_Strict_Alignment): Remove new check on | |
172 | Has_Aliased_Components for array types. | |
173 | ||
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 | ||
185 | * scng.adb (Scan): In Ada2020, a left-bracket indicates the | |
186 | start of an homogenous aggregate. | |

193 | * sinfo.ads, sinfo.adb (Is_Homogeneous_Aggregate): New flag on | |
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 | ||
209 | 2019-12-16 Eric Botcazou <ebotcazou@adacore.com> | |

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. | |
250 | (Constrain_Array): Likewise on the array. | |
251 | (Record_Type_Declaration: Likewise on the tag. | |
252 | (Array_Type_Declaration): Also set the | |
253 | Has_Independent_Components flag along with | |
254 | Has_Aliased_Components on the array. | |

263 | flag along with Is_Aliased on the formal. | |
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. | |
278 | (Is_Subcomponent_Of_Atomic_Object): Remove redundant test. | |
279 | (Is_Volatile_Full_Access_Object): New predicate. | |
280 | (Is_Volatile_Prefix): Rename into... | |

283 | (Object_Has_Volatile_Components): Delete. | |
284 | (Is_Volatile_Object): Simplify. | |
285 | * gcc-interface/trans.c (node_is_volatile_full_access): Adjust | |
286 | comment. | |

291 | stack. Call Scopes all over the parser. Add | |
292 | SIS_Aspect_Import_Seen flag. | |
293 | * par-ch6.adb (P_Subprogram): Initialize SIS_Aspect_Import_Seen | |
294 | to False at the start, and check it at the end. | |
295 | * par-ch13.adb (Get_Aspect_Specifications): Set | |
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, | |

304 | fix consistency issues. Call Component_Type on the Etype of E. | |
305 | (Independent_Components): Remove local variable. | |
306 | * sem_util.adb (Is_Subcomponent_Of_Atomic_Object): Properly deal | |
307 | with prefixes that are access values. | |

317 | of Atomic and Volatile_Full_Access. | |
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. | |
331 | <N_Assignment_Statement>: Call get_atomic_access for the name instead | |
332 | of [outer_]atomic_access_required_p. Adjust call to Call_to_gnu. | |
333 | <N_Function_Call>: Adjust call to Call_to_gnu. | |
334 | (get_controlling_type): Fix typo in comment. | |
335 | ||
336 | 2019-12-16 Eric Botcazou <ebotcazou@adacore.com> | |

340 | * opt.ads (Ada_Version_Type): Add Convention C and WARNING line. | |
341 | (Ada_Version): Add WARNING line. | |
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 | |

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 | |

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 | |

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 | ||

640 | Analyze_Refined_Depends_In_Decl_Part, | |
641 | Analyze_Refined_Global_In_Decl_Part, Check_Missing_Part_Of): | |

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 | ||

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 | |

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 | ||

1592 | the expression and reset the Loop_Actions for each loop | |
1593 | generated for an others choice. | |

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. | |

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. | |

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. | |

1659 | 'Component_Size "by hand" instead of using 'Size. | |

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 | |

2786 | Issue a warning if the condition is not known at compile time. | |
2787 | The key point is that the warning must be given only for pragmas | |
2788 | deferred to the back end, because the back end discovers | |
2789 | additional values that are known at compile time. Previous | |
2790 | changes in this ticket have enabled this by deferring to the | |
2791 | back end without checking for special cases such as 'Size. | |

2816 | processing to the back end in all cases where the pragma's | |
2817 | condition is not known at compile time during the front end | |
2818 | (except in generics), as opposed to detecting 'Size attributes | |
2819 | and the like. This ensures that we take advantage of whatever | |
2820 | can be compile-time known after running the back end, as opposed | |
2821 | to having the front end guess what the back end can do. Remove | |
2822 | a little duplicated code at the call site. | |

2851 | invoke Add_Inlined_Instance. Also deal with the case where the | |

3600 | ||
3601 | * exp_ch4.adb (Expand_N_In): Do not suggest the use of attribute | |
3602 | 'Valid as a replacement for a range check on a discrete type | |
3603 | when the bounds of the range are given by type conversions, | |
3604 | because in such a case there are distinct types involved and the | |

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. | |
