3 * exp_ch6.adb (Make_Build_In_Place_Call_In_Object_Declaration): Handle
4 properly object declarations with initializations that are
5 build-in-place function calls, when there is an address specification,
6 either as an aspect specification or an explicit attribute
7 specification clause, for the initialized object.
8 * freeze.adb (Check_Address_Clause): Do not remove side-effects from
9 initial expressions in the case of a build-in-place call.
11 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
13 * sem_eval.adb (Is_Null_Range): Retrieve the full view when called on a
14 private (sub)type; refactor to avoid early return statement.
15 (Not_Null_Range): Same as above.
17 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
19 * freeze.adb (Freeze_Entity): Ensure that a Ghost type is not
20 concurrent, nor effectively volatile.
21 * ghost.adb (Check_Ghost_Type): New routine.
22 * ghost.ads (Check_Ghost_Type): New routine.
23 * sem_util.adb (Is_Declaration): Reimplemented. The routine can now
24 consider specific subsets of declarations.
25 (Is_Declaration_Other_Than_Renaming): Removed. Its functionality is
26 replicated by Is_Declaration.
27 * sem_util.ads (Is_Declaration): New parameter profile. Update the
29 (Is_Declaration_Other_Than_Renaming): Removed.
31 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
33 * sem_ch5.adb (Analyze_Assignment): Assignments to variables that act
34 as Part_Of consituents of single protected types are illegal when they
35 take place inside a protected function.
36 (Diagnose_Non_Variable_Lhs): Use Within_Function to check for an
38 (Is_Protected_Part_Of_Constituent): New routine.
39 (Within_Function): New routine.

43 Bump copyright notices to 2018.
45 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
47 * binde.adb, par-ch6.adb, par-ch9.adb, sem_ch12.adb, sem_ch13.adb:
50 2018-01-11 Justin Squirek <squirek@adacore.com>
52 * par-ch6.adb (Scan_Body_Or_Expression_Function): Add additional check
53 to make sure a given expression function is properly parenthesized.
55 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
57 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Check the
58 categorization of a subprogram body which does not complete a previous
61 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
63 * sem_ch10.adb (Check_Private_Child_Unit): Ensure that the enclosing
64 scope of package Ada is Standard.
66 2018-01-11 Ed Schonberg <schonberg@adacore.com>
68 * sem_ch13.adb (Replace_Type_Ref): Handle properly reference to a
69 subcomponent of the current entity when building the body for a dynamic
70 predicate function for a record with composite subcomponents.

80 (Make_Build_In_Place_Call_In_Object_Declaration): Update the call to
81 Establish_Transient_Scope.
82 * exp_ch7.adb (Establish_Transient_Scope): Restructured. Delegate the
83 management of the secondary stack to an enclosing scope if there is no
84 suitable construct to wrap, and the transient scope was intended to
85 manage the secondary stack.
86 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
87 is a valid boundary for a transient expression which comes from the
88 statements of the alternative, otherwise alternatives cannot be
89 wrapped. Assignments of controlled objects which have controlled
90 actions suppressed now stop the traversal as there is no point in
91 looking for an enclosing construct. Add several N_xxx_Body choices to
92 the termination conditions for completeness.
93 * exp_ch7.ads (Establish_Transient_Scope): Update the parameter profile
94 and the associated comment on usage.
95 * exp_smem.adb (Add_Shared_Var_Lock_Procs): Update the call to
96 Establish_Transient_Scope.
97 (Add_Write_After): Update the call to Establish_Transient_Scope.
98 * sem_res.adb (Check_Initialization_Call): Removed.
99 (Resolve_Actuals): Account for additional cases where finalization
100 actions are required by utilizing predicate Needs_Finalization rather
102 (Resolve_Call): Type initialization procedures can now utilize
103 transient scopes to manage the secondary stack, thus preventing leaks
104 during initialization. Remove the previous kludgy algorithm which
105 attempts to manage the secondary stack at the object creation site.
107 2018-01-11 Jerome Lambourg <lambourg@adacore.com>

148 2018-01-11 Ed Schonberg <schonberg@adacore.com>
150 * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
151 formsl type corresponding to the actual fixed point type is private,
152 because in this case there can be no suspicious arithmetic operations
153 in the generic unless they reference a formal subprogram. Clarify
156 2018-01-11 Javier Miranda <miranda@adacore.com>
158 * exp_util.adb (Remove_Side_Effects): No action done for functions
159 returning class-wide types since it requires generating code using
160 'reference and the CCG target has no secondary stack.
161 * gnat1drv.adb: Disable building static dispatch tables when generating
164 2018-01-11 Piotr Trojanek <trojanek@adacore.com>

180 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
182 * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
183 if it contains at least one component declaration employing a function
184 call returning on the secondary stack.

203 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
204 has a delayed aspect which must be processed at the point the type is
205 frozen. This mimics what is done when the predicate is provided by a

221 Default_Sec_Stack_Size.
222 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
223 limit check so that the integer index does not overflow. Check the
224 dynamic stack allocation does not cause the secondary stack pointer to
226 (SS_Info): Align colons.
227 (SS_Init): Cover the case when bootstraping with an old compiler that
228 does not set Default_SS_Size.
230 2018-01-11 Ed Schonberg <schonberg@adacore.com>
232 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
233 legality of an inherited operation that may require overriding, ignore
234 primitive_wrappers that correspond to explicit operations that override
235 an interface primitive.
236 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
237 operation to which the class-wide expression applies is a protected op.
238 with a primitive_wrapper, verify that the updated inherited expression
239 does not contain an internal call to a protected function. This
240 completes the implementation of AI12-0166.
242 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
244 * ali.adb: Document the remaining letters available for ALI lines.
245 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
246 * ali.ads: Update type With_Record. Field
247 Implicit_With_From_Instantiation is no longer in use. Add field
249 * csinfo.adb (CSinfo): Remove the setup for attribute
250 Implicit_With_From_Instantiation.
251 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
252 either implicitly or explicitly withed.
253 (Is_Implicit_With_Clause): New routine.
254 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
255 confusion with the with clause attribute by the same name.
256 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
257 * rtsfind.adb (Maybe_Add_With): Code cleanup.
258 * sem_ch8.adb (Present_System_Aux): Code cleanup.

261 (Implicit_With_On_Parent): Mark the with clause as generated for a
263 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
264 instantiation are no longer marked as Implicit_With_From_Instantiation
265 because they are already marked as implicit.
266 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
267 which marks implicit with clauses as related to an instantiation.
268 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
269 (Parent_With): New routine.
270 (Set_Implicit_With_From_Instantiation): Removed.
271 (Set_Parent_With): New routine.
272 * sinfo.ads: Update the documentation of attribute Implicit_With.
273 Remove attribute Implicit_With_From_Instantiation along with
274 occurrences in nodes. Add attribute Parent_With along with occurrences
276 (Implicit_With_From_Instantiation): Removed along with pragma Inline.
277 (Parent_With): New routine along with pragma Inline.
278 (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.
279 (Set_Parent_With): New routine along with pragma Inline.
281 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>

284 entity when the enclosing construct is a body.
286 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
288 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
289 Secondary_Stack_Size handling as a pragma is now generated for the
290 corresponding aspect instead of an attribute. Pragma expression is
291 relocated instead of evaluated. Discriminant of the corresponding
292 record type is referenced rather than the type discriminant.
293 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
294 Secondary_Stack_Size rep item checks to only look for the pragma rep.
295 * sem_ch13.adb (Analyze_One_Aspect): Transform
296 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
297 because the attribute does not have visibility on a task type's
298 discriminants when the type's definition is expanded.
299 (Analyze_Attribute_Definition_Clause): Remove handling of
300 Attribute_Secondary_Stack_Size.
301 * snames.adb-tmpl, snames.ads-tmpl: Remove

308 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
310 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
311 individual action because the action may denote a complex expression,
312 such as a case statement, which in turn may contain additional

317 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
318 analysis on a copy of the expression with a copy of the index variable,
319 because full expansion will rewrite construct into a loop with the
320 original loop variable.
321 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
322 expression is an iterated component association. Full analysis takes
323 place when construct is rewritten as a loop.
324 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
325 is not safe for in-place assignment.
326 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
327 entity with no homonym and no other entity in the scope.
329 2018-01-11 Justin Squirek <squirek@adacore.com>

349 Allow E_Discriminant.
351 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
353 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
354 for atomic access once the component size is taken into account and
355 also do it if the component type is Atomic or Volatile_Full_Access.
357 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
