3 * exp_ch3.adb (Default_Initialize_Object): Call New_Copy_Tree on the
4 result of Get_Simple_Init_Value and pass the source location of the
5 object declaration's object_definition.
7 2018-01-11 Ed Schonberg <schonberg@adacore.com>
9 * exp_ch6.adb (Make_Build_In_Place_Call_In_Object_Declaration): Handle
10 properly object declarations with initializations that are
11 build-in-place function calls, when there is an address specification,
12 either as an aspect specification or an explicit attribute
13 specification clause, for the initialized object.
14 * freeze.adb (Check_Address_Clause): Do not remove side-effects from
15 initial expressions in the case of a build-in-place call.
17 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
19 * sem_eval.adb (Is_Null_Range): Retrieve the full view when called on a
20 private (sub)type; refactor to avoid early return statement.
21 (Not_Null_Range): Same as above.
23 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
25 * freeze.adb (Freeze_Entity): Ensure that a Ghost type is not
26 concurrent, nor effectively volatile.
27 * ghost.adb (Check_Ghost_Type): New routine.
28 * ghost.ads (Check_Ghost_Type): New routine.
29 * sem_util.adb (Is_Declaration): Reimplemented. The routine can now
30 consider specific subsets of declarations.
31 (Is_Declaration_Other_Than_Renaming): Removed. Its functionality is
32 replicated by Is_Declaration.
33 * sem_util.ads (Is_Declaration): New parameter profile. Update the
35 (Is_Declaration_Other_Than_Renaming): Removed.
37 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
39 * sem_ch5.adb (Analyze_Assignment): Assignments to variables that act
40 as Part_Of consituents of single protected types are illegal when they
41 take place inside a protected function.
42 (Diagnose_Non_Variable_Lhs): Use Within_Function to check for an
44 (Is_Protected_Part_Of_Constituent): New routine.
45 (Within_Function): New routine.

51 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
53 * binde.adb, par-ch6.adb, par-ch9.adb, sem_ch12.adb, sem_ch13.adb:
56 2018-01-11 Justin Squirek <squirek@adacore.com>
58 * par-ch6.adb (Scan_Body_Or_Expression_Function): Add additional check
59 to make sure a given expression function is properly parenthesized.
61 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
63 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Check the
64 categorization of a subprogram body which does not complete a previous
67 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
69 * sem_ch10.adb (Check_Private_Child_Unit): Ensure that the enclosing
70 scope of package Ada is Standard.
72 2018-01-11 Ed Schonberg <schonberg@adacore.com>
74 * sem_ch13.adb (Replace_Type_Ref): Handle properly reference to a
75 subcomponent of the current entity when building the body for a dynamic
76 predicate function for a record with composite subcomponents.

86 (Make_Build_In_Place_Call_In_Object_Declaration): Update the call to
87 Establish_Transient_Scope.
88 * exp_ch7.adb (Establish_Transient_Scope): Restructured. Delegate the
89 management of the secondary stack to an enclosing scope if there is no
90 suitable construct to wrap, and the transient scope was intended to
91 manage the secondary stack.
92 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
93 is a valid boundary for a transient expression which comes from the
94 statements of the alternative, otherwise alternatives cannot be
95 wrapped. Assignments of controlled objects which have controlled
96 actions suppressed now stop the traversal as there is no point in
97 looking for an enclosing construct. Add several N_xxx_Body choices to
98 the termination conditions for completeness.
99 * exp_ch7.ads (Establish_Transient_Scope): Update the parameter profile
100 and the associated comment on usage.
101 * exp_smem.adb (Add_Shared_Var_Lock_Procs): Update the call to
102 Establish_Transient_Scope.
103 (Add_Write_After): Update the call to Establish_Transient_Scope.
104 * sem_res.adb (Check_Initialization_Call): Removed.
105 (Resolve_Actuals): Account for additional cases where finalization
106 actions are required by utilizing predicate Needs_Finalization rather
108 (Resolve_Call): Type initialization procedures can now utilize
109 transient scopes to manage the secondary stack, thus preventing leaks
110 during initialization. Remove the previous kludgy algorithm which
111 attempts to manage the secondary stack at the object creation site.
113 2018-01-11 Jerome Lambourg <lambourg@adacore.com>

154 2018-01-11 Ed Schonberg <schonberg@adacore.com>
156 * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
157 formsl type corresponding to the actual fixed point type is private,
158 because in this case there can be no suspicious arithmetic operations
159 in the generic unless they reference a formal subprogram. Clarify
162 2018-01-11 Javier Miranda <miranda@adacore.com>
164 * exp_util.adb (Remove_Side_Effects): No action done for functions
165 returning class-wide types since it requires generating code using
166 'reference and the CCG target has no secondary stack.
167 * gnat1drv.adb: Disable building static dispatch tables when generating

186 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
188 * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
189 if it contains at least one component declaration employing a function
190 call returning on the secondary stack.

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

227 Default_Sec_Stack_Size.
228 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
229 limit check so that the integer index does not overflow. Check the
230 dynamic stack allocation does not cause the secondary stack pointer to
232 (SS_Info): Align colons.
233 (SS_Init): Cover the case when bootstraping with an old compiler that
234 does not set Default_SS_Size.
236 2018-01-11 Ed Schonberg <schonberg@adacore.com>
238 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
239 legality of an inherited operation that may require overriding, ignore
240 primitive_wrappers that correspond to explicit operations that override
241 an interface primitive.
242 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
243 operation to which the class-wide expression applies is a protected op.
244 with a primitive_wrapper, verify that the updated inherited expression
245 does not contain an internal call to a protected function. This
246 completes the implementation of AI12-0166.
248 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
250 * ali.adb: Document the remaining letters available for ALI lines.
251 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
252 * ali.ads: Update type With_Record. Field
253 Implicit_With_From_Instantiation is no longer in use. Add field
255 * csinfo.adb (CSinfo): Remove the setup for attribute
256 Implicit_With_From_Instantiation.
257 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
258 either implicitly or explicitly withed.
259 (Is_Implicit_With_Clause): New routine.
260 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
261 confusion with the with clause attribute by the same name.
262 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
263 * rtsfind.adb (Maybe_Add_With): Code cleanup.
264 * sem_ch8.adb (Present_System_Aux): Code cleanup.

269 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
270 instantiation are no longer marked as Implicit_With_From_Instantiation
271 because they are already marked as implicit.
272 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
273 which marks implicit with clauses as related to an instantiation.
274 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
275 (Parent_With): New routine.
276 (Set_Implicit_With_From_Instantiation): Removed.
277 (Set_Parent_With): New routine.

279 Remove attribute Implicit_With_From_Instantiation along with
280 occurrences in nodes. Add attribute Parent_With along with occurrences
282 (Implicit_With_From_Instantiation): Removed along with pragma Inline.
283 (Parent_With): New routine along with pragma Inline.
284 (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.
285 (Set_Parent_With): New routine along with pragma Inline.

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

316 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
317 individual action because the action may denote a complex expression,
318 such as a case statement, which in turn may contain additional

323 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
324 analysis on a copy of the expression with a copy of the index variable,
325 because full expansion will rewrite construct into a loop with the
326 original loop variable.
327 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
328 expression is an iterated component association. Full analysis takes
329 place when construct is rewritten as a loop.
330 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
331 is not safe for in-place assignment.
332 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
333 entity with no homonym and no other entity in the scope.
335 2018-01-11 Justin Squirek <squirek@adacore.com>

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