[official-gcc.git] / gcc / ada / ChangeLog
blobc011deb2b24d845f871020f4acb2eeba9bf9776f
1 2023-11-10  Andris Pavēnis  <andris.pavenis@iki.fi>
3         * expect.c (__gnat_waitpid): fix syntax errors
5 2023-11-09  Simon Wright  <simon@pushface.org>
7         PR ada/111813
8         * libgnat/a-calfor.adb (Value (2)): Allow values of
9         parameter Elapsed_Time greater than or equal to 24 hours, by doing
10         the hour calculations in Natural rather than Hour_Number (0 ..
11         23). Calculate the result directly rather than by using Seconds_Of
12         (whose Hour parameter is of type Hour_Number).
13         If an exception occurs of type Constraint_Error, re-raise it
14         rather than raising a new CE.
16 2023-11-07  Joseph Myers  <joseph@codesourcery.com>
18         * gcc-interface/utils.cc (flag_isoc2x): Rename to flag_isoc23.
20 2023-11-07  Eric Botcazou  <ebotcazou@adacore.com>
22         * gcc-interface/decl.cc (gnat_to_gnu_entity) <E_Variable>: Apply the
23         specific rewriting done for an aliased object with an unconstrained
24         array nominal subtype in the renaming case too.
26 2023-11-07  Eric Botcazou  <ebotcazou@adacore.com>
28         * gcc-interface/trans.cc (gnat_gimplify_expr) <CALL_EXPR>: Delete.
30 2023-11-07  Bob Duff  <duff@adacore.com>
32         * sem_ch13.ads (Set_Enum_Esize): Do not set alignment.
33         * sem_ch13.adb (Set_Enum_Esize): Do not set alignment. Archaeology
34         seems to show that this line of code dates from when "Alignment =
35         0" meant "the Alignment is not known at compile time" and "the
36         Alignment is not yet known at compile time" as well as "the
37         Alignment is zero". In any case, it seems to be unnecessary, and
38         in this case harmful, because gigi would crash. Alignment_Clause
39         is set (because there is one), so gigi would query the Alignment,
40         but Alignment was destroyed.
42 2023-11-07  Julien Bortolussi  <bortolussi@adacore.com>
44         * doc/share/conf.py: Changed the background color and the logo.
46 2023-11-07  Eric Botcazou  <ebotcazou@adacore.com>
48         * gen_il-fields.ads (Opt_Field_Enum): Add Compare_Type.
49         * gen_il-gen-gen_nodes.adb (N_Op_Eq): Likewise.
50         (N_Op_Ge): Likewise.
51         (N_Op_Gt): Likewise.
52         (N_Op_Le): Likewise.
53         (N_Op_Lt): Likewise.
54         (N_Op_Ne): Likewise.
55         * sinfo.ads (Compare_Type): Document new field.
56         * sem_ch4.adb (Analyze_Comparison_Equality_Op): If the entity is
57         already present, set the Compare_Type on overloaded operands if it
58         is present on the node.
59         * sem_ch12.adb (Check_Private_View): Look into the Compare_Type
60         instead of the Etype for comparison operators.
61         (Copy_Generic_Node): Remove obsolete code for comparison
62         operators.
63         (Save_Global_References.Save_References): Do not walk into the
64         descendants of N_Implicit_Label_Declaration nodes.
65         (Save_Global_References.Set_Global_Type): Look into the
66         Compare_Type instead of the Etype for comparison operators.
67         * sem_res.adb (Resolve_Comparison_Op): Set Compare_Type.
68         (Resolve_Equality_Op): Likewise.
70 2023-11-07  Ronan Desplanques  <desplanques@adacore.com>
72         * adaint.c (__gnat_file_time): Fix Windows version.
74 2023-11-07  Eric Botcazou  <ebotcazou@adacore.com>
76         * exp_ch3.adb (Expand_N_Object_Declaration): Fold initialization
77         expression of Nominal_Subtype_Is_Constrained_Array constant into
78         the computation of Rewrite_As_Renaming and remove the constant.
79         Set it to True for an aliased array with unconstrained nominal
80         subtype if the subtype of the expression is also unconstrained.
82 2023-11-07  Piotr Trojanek  <trojanek@adacore.com>
84         * exp_util.adb (Add_Own_DIC, Add_Own_Invariants): Store the aspect
85         expression in Expression_Copy.
87 2023-11-07  Yannick Moy  <moy@adacore.com>
89         * exp_aggr.adb: Apply the renaming.
90         * exp_ch3.adb: Same.
91         * exp_ch4.adb: Same.
92         * exp_ch6.adb: Same.
93         * exp_ch7.adb: Same.
94         * exp_util.adb: Same.
95         * freeze.adb: Same.
96         * sem_aggr.adb: Same.
97         * sem_attr.adb: Same.
98         * sem_aux.adb: Alphabetize Is_Limited_Type. Rename.
99         * sem_aux.ads: Same.
100         * sem_ch3.adb: Apply the renaming.
101         * sem_ch6.adb: Same.
102         * sem_ch8.adb: Same.
103         * sem_prag.adb: Same.
104         * sem_res.adb: Same.
105         * sem_util.adb: Same.
107 2023-11-07  Viljar Indus  <indus@adacore.com>
109         * aspects.adb (Exchange_Aspects): Removed. This method was
110         typically called after a Rewrite method. Now since the Rewrite
111         switches the aspects between the new and the old node it is no
112         longer needed.
113         (Has_Aspects): Converted to a utility method that performs the same
114         before as the previous Has_Aspects field did. Meaning it shows whether
115         a node actually has aspects or not.
116         (Copy_Aspects): New utility method that performs a deep copy of the
117         From nodes aspects.
118         (Aspect_Specfications): Removed. No longer needed. Replaced
119         by the primitive operation for the Aspect_Specification fields.
120         (Set_Aspect_Specifications): Likewise.
121         (Aspect_Specifications_Hash_Table): Remove the table and all the
122         utility methods for storing the old aspects.
123         * aspects.ads: Likewise.
124         * atree.adb (Copy_Separate_Tree): Remove custom code for aspects.
125         (New_Copy): Likewise.
126         (Replace): Likewise.
127         (Rewrite): Likewise.
128         * exp_ch3.adb (Expand_N_Object_Declaration): Keep the aspects from the old node.
129         * exp_ch6.adb (Validate_Subprogram_Calls): Previously aspects were ignored
130         because they were not on the tree. Explicitly ignore them here
131         when traversing the tree.
132         * exp_unst.adb (Build_Tables): Likewise
133         * gen_il-fields.ads: Remove Has_Aspects and add
134         Aspect_Specifications fields.
135         * gen_il-gen-gen_nodes.adb: Add Aspect_Specification fields
136         for all nodes that can have aspects. Additionally add
137         Expression_Copy for Aspect_Speficiations to avoid reusing
138         the Associated_Node for generic instantiation and aspect
139         analysis.
140         * ghost.adb (Remove_Ignored_Ghost_Node): Remove call to Remove_Aspects.
141         The rewritten node is a Null_Statement that cannot have aspects
142         and there is not anything to gain from removing them from the
143         Orignal_Node of N since it technically is not part of the active
144         tree.
145         * inline.adb (Process_Formals_In_Aspects): Simplify code for node traversal.
146         * par-ch13.adb: Avoid setting the parent explicitly for the
147         Aspect_Specifications list. This is done explicitly in the setter.
148         * par-ch6.adb: Likewise.
149         * par_sco.adb (Traverse_Aspects): Handle early return.
150         * sem_ch10.adb: Simplify code for Analyze_Aspect_Specifications.
151         * sem_ch11.adb: Likewise.
152         * sem_ch12.adb (Analyze_Formal_Derived_Interface_Type): Keep the aspects from
153         the orignal node after rewrite.
154         (Analyze_Formal_Derived_Type): Likewise.
155         (Analyze_Formal_Interface_Type): Likewise.
156         (Analyze_Formal_Object_Declaration): Simplify code for
157         Analyze_Aspect_Specifications.
158         (Analyze_Formal_Package_Declaration): Likewise.
159         (Analyze_Formal_Subprogram_Declaration): Likewise.
160         (Analyze_Formal_Type_Declaration): Likewise.
161         (Analyze_Generic_Package_Declaration): Remove Exchange_Aspects.
162         The new node already has the correct aspects after the rewrite.
163         Also simplify code for Analyze_Aspect_Specifications.
164         (Analyze_Generic_Subprogram_Declaration): Likewise.
165         (Analyze_Package_Instantiation): Simplify code for
166         Analyze_Aspect_Specifications.
167         (Build_Instance_Compilation_Unit_Nodes): Remove explicit copy of
168         aspects that is no longer needed.
169         (Save_References): Update the traversal code to handle
170         Aspect_Specifications in the tree.
171         (Copy_Generic_Node): Remove explicit copy for aspects. New_Copy
172         took care of that already.
173         * sem_ch13.adb (Analyze_Aspect_Specifications): Add early return to simplify
174         code for its calls. Avoid reusing the Entity(Associated_Node)
175         field for storing the original expression. Instead use the
176         new Expression_Copy field since Entity(Associated_Node) is
177         also used in generic instantiation.
178         (Analyze_Aspects_On_Subprogram_Body_Or_Stub): Simlify call
179         to Analyze_Aspect_Specifications.
180         (Check_Aspect_At_End_Of_Declarations): Use Expression_Copy
181         instead of Entity.
182         (Check_Aspect_At_Freeze_Point): Likewise.
183         * sem_ch3.adb: Simplify calls to Analyze_Aspect_Specifications.

191         (Analyze_Null_Procedure): Keep the aspects from the
192         original node after a rewrite.
193         (Analyze_Subprogram_Body_Helper): Simplify calls to
194         Analyze_Aspect_Specifications.
195         (Analyze_Subprogram_Declaration): Likewise.
196         * sem_ch7.adb (Analyze_Package_Body_Helper): Remove Exchange aspects
197         that is no longer needed. Simplify call to
198         Analyze_Aspect_Specifications.
199         (Analyze_Package_Declaration): Simplify call to
200         Analyze_Aspect_Specifications.
201         (Analyze_Private_Type_Declaration): Likewise.
202         * sem_ch8.adb: Simplify calls to
203         Analyze_Aspect_Specifications.

214         (Analyze_Task_Body): Simplify call to
215         Analyze_Aspect_Specifications.
216         (Analyze_Task_Type_Declaration): Simplify calls to
217         Analyze_Aspect_Specifications.
218         * sem_dim.adb: Remove explicitly setting the parents
219         for the Aspect_Specification list.
220         * sem_disp.adb: Remove the with that is no longer
221         required since Aspect_Specifications is a node operation now.
222         * sem_util.adb (Copy_Node_With_Replacement): Remove explicit code for aspects.
223         * treepr.adb (Print_Field): Remove the version that was used for printing
224         aspects.
225         (Print_Node): Remove aspect specific code.
227 2023-11-07  Eric Botcazou  <ebotcazou@adacore.com>
229         * gen_il-gen-gen_nodes.adb (N_Op_Boolean): Fix description.
230         * sem_ch4.adb (Analyze_Comparison_Equality_Op): Tidy up.
231         * sem_ch12.adb (Copy_Generic_Node): Use N_Op_Compare subtype.
233 2023-11-07  Piotr Trojanek  <trojanek@adacore.com>
235         * exp_ch6.adb, exp_disp.adb, sem_ch13.adb, sem_ch3.adb: Fix newly
236         detected violations.
238 2023-11-07  Piotr Trojanek  <trojanek@adacore.com>
240         * sem_ch3.adb, sem_ch4.adb, sem_eval.adb: Fix newly detected
241         violations.
243 2023-11-07  Ronan Desplanques  <desplanques@adacore.com>
245         * doc/gnat_ugn/building_executable_programs_with_gnat.rst: Fix
246         -gnatwc documentation.
247         * gnat_ugn.texi: Regenerate.
249 2023-11-07  Steve Baird  <baird@adacore.com>
251         * local_restrict.ads: A new package. Declares Local_Restriction
252         enumeration type and provides operations to check for local
253         restriction violations.
254         * local_restrict.adb: Corresponding package body. Replace "not
255         Present (X)" calls with "No (X)" calls.
256         * aspects.ads: Add a new enumeration elements,
257         Aspect_Local_Restrictions and Aspect_User_Aspect, to the Aspect_Id
258         enumeration type. Update Aspect_Id-indexed aggregates. Add nested
259         package User_Aspect_Support to manage two pieces of state. One is
260         a map from identifiers to User_Aspect_Definition pragmas (updated
261         when such a pragma is encountered). The other is an
262         access-to-subprogram variable that is introduced in order to keep
263         the bulk of semantics out of the closure of package Aspects while
264         allowing a call from aspects.adb to the sem_ch13 procedure that
265         analyzes a User_Aspect aspect specification.
266         * aspects.adb (Find_Aspect): Cope with a case of a block statement
267         with an empty parent. It is not clear whether this is papering
268         over a compiler bug. Add indirect call through the aforementioned
269         access-to-subprogram variable when Find_Aspect enounters an
270         unanalyzed User_Aspect aspect specification. If Find_Aspect is
271         called looking for aspect Foo, then a User_Aspect specification
272         might generate (during analysis) a Foo aspect specification. So
273         the Find_Aspect call needs to trigger that analysis if it has not
274         already taken place. Provide a body for package
275         User_Aspect_Support. Replace "not Present (X)" call with "No (X)"
276         call.
277         * freeze.adb (Freeze_Subprogram): Check local restriction
278         compatibility when a dispatching operation is overridden.
279         * par-prag.adb: Add support for parsing a User_Aspect_Definition
280         pragma.
281         * restrict.ads: We'd like to have the body of package Restrict
282         include a call to a procedure declared in package Local_Restrict.
283         Doing that in the obvious way pulls most of semantics into the
284         closure of package Restrict, and that turns out to cause problems.
285         So we introduce a level of indirection and instead call through an
286         access-to-subprogram value. In this unit, we declare the
287         access-to-subprogram type and object.
288         * restrict.adb (Check Restriction): When a construct is
289         encountered that could violate a global restriction (depending on
290         whether the given restriction is in effect), Check_Restriction is
291         called. At this point, we also check for a violation of any
292         corresponding local restriction that is in effect. For reasons
293         described above, this check is performed via an indirect call.
294         * sem_ch13.ads (Parse_Aspect_Local_Restrictions): A new function,
295         similar to the existing Parse_Aspect_Xxx subprograms.
296         * sem_ch13.adb: Perform semantic analysis of Local_Restrictions
297         and User_Aspect aspect specifications. Declare and call new
298         Validate_Aspect_Local_Restrictions and
299         Analyze_User_Aspect_Aspect_Specification procedures (a reference
300         to the latter is registered during package elaboration). In
301         Analyze_Aspect_Specifications, do not set the Analyzed flag of a
302         User_Aspect aspect specification. Replace "not Present (X)" call
303         with "No (X)" call. Replace 'Image with 'Img in a case where the
304         prefix of the attribute reference is an object; this is done to
305         accomodate older compilers.
306         * sem_ch6.adb (Check_Subtype_Conformant): Include in subtype
307         conformance check a check for overriding-related compatibility of
308         local restrictions.
309         * sem_ch8.adb (Analyze_Subprogram_Renaming): In the case of an
310         instance of a generic that takes a formal subprogram, check that
311         formal and actual are compatible with respect to local
312         restrictions.
313         * sem_prag.adb: Add support for User_Aspect_Definition pragma.
314         * sem_res.adb (Resolve_Call): Check caller/callee compatibility
315         with respect to local restrictions.
316         * snames.ads-tmpl: Add Name_Local_Restrictions, Name_User_Aspect,
317         and Name_User_Aspect_Definition constants.
318         * doc/gnat_rm/implementation_defined_aspects.rst: Document new
319         aspects.
320         * doc/gnat_rm/implementation_defined_pragmas.rst: Document new
321         pragma.
322         * doc/gnat_ugn/the_gnat_compilation_model.rst: Add
323         User_Aspect_Definition to list of GNAT pragmas.
324         * gcc-interface/Make-lang.in: Add local_restrict.o.
325         * gnat-style.texi: Regenerate.
326         * gnat_rm.texi: Regenerate.
327         * gnat_ugn.texi: Regenerate.
329 2023-11-07  Bob Duff  <duff@adacore.com>
331         * sem_ch4.adb (Is_Private_Overriding): Return True in the case
332         where a primitive operation is publicly inherited but privately
333         overridden.
335 2023-11-07  Piotr Trojanek  <trojanek@adacore.com>
337         * exp_pakd.adb (Expand_Bit_Packed_Element_Set): Remove code from the
338         ELSE branch, because it was is identical to code before the IF
339         statements itself.
341 2023-11-07  Piotr Trojanek  <trojanek@adacore.com>
343         * exp_pakd.adb (Expand_Bit_Packed_Element_Set): Change Ctyp and Csiz
344         from variables to constants and compute them using the nominal type
345         of the assigned array object.

744         * einfo-utils.adb: As for spec.
745         * frontend.adb (Frontend): Remove unnecessary "return;".
746         * gen_il-types.ads (Scope_Kind): New union type.
747         * gen_il-gen-gen_entities.adb (Scope_Kind): New union type.
748         * sem.ads: Move "with Einfo.Entities;" from body to spec.
749         (Scope_Stack_Entry): Declare Entity to be of Scope_Kind_Id to get
750         predicate checks. We had previously been putting non-scopes on the
751         scope stack; this prevents such anomalies.
752         * sem.adb: Move "with Einfo.Entities;" from body to spec.
753         * sem_ch8.ads: Move "with Einfo.Entities;" from body to spec. Add
754         "with Types;".
755         (Push_Scope): Use Scope_Kind_Id to get predicate checks.
756         * sem_ch8.adb: Move "with Einfo.Entities;" from body to spec. Add
757         "with Types;".
758         (Push_Scope): Use Scope_Kind_Id to get predicate checks.
759         (Pop_Scope): Use Scope_Kind_Id on popped entity to get predicate
760         checks. This prevents anomalies where a scope pushed onto the
761         stack is later mutated to a nonscope before being popped.
762         * sem_util.ads (Find_Enclosing_Scope): Add postcondition to ensure
763         that the enclosing scope of a node N is not the same node N.
764         Clearly, N does not enclose itself.
765         * sem_util.adb (Find_Enclosing_Scope): There were several bugs
766         where Find_Enclosing_Scope(N) = N. For example, if N is an entity,
767         then we would typically go up to its declaration, and then back
768         down to the Defining_Entity of the declaration, which is N itself.
769         There were other cases where Find_Enclosing_Scope of an entity
770         disagreed with Scope. Clearly, Find_Enclosing_Scope and Scope
771         should agree (when both are defined). Such bugs caused latent bugs
772         in accessibility.adb related to 'Old, and fixing bugs here caused
773         such bugs to be revealed. These are fixed by calling Scope when N
774         is an entity.

803         available compiling generic units or when the sources have errors,
804         since expansion is then disabled.
806 2023-09-14  Javier Miranda  <miranda@adacore.com>
808         * sem_util.adb (Large_Max_Size_Mutable): Protect access to

850         * sem_type.adb (Iface_Present_In_Ancestor): Only look at the list of
851         interfaces for types that allow it. The guard is a high-level equivalent
852         of the entity kinds listed in the preconditon of the Interfaces query.

4606         Reinit_Field_To_Zero of that, thus modifying the field for lots of
4607         subtypes other than S. Disable in the to/from E_Void cases. Misc

4609         * gen_il-gen-gen_entities.adb: Define First_Entity, Last_Entity,

4658         RList.
4659         * doc/gnat_ugn/building_executable_programs_with_gnat.rst:
4660         Document the -gnatw_s switch (and the corresponding -gnatw_S

4685         only handle cases where the right type is a[sic] integer", because
