45 * exp_ch3.adb (Default_Initialize_Object): Call New_Copy_Tree on the
46 result of Get_Simple_Init_Value and pass the source location of the
47 object declaration's object_definition.
49 2018-01-11 Ed Schonberg <schonberg@adacore.com>
51 * exp_ch6.adb (Make_Build_In_Place_Call_In_Object_Declaration): Handle
52 properly object declarations with initializations that are
53 build-in-place function calls, when there is an address specification,
54 either as an aspect specification or an explicit attribute
55 specification clause, for the initialized object.
56 * freeze.adb (Check_Address_Clause): Do not remove side-effects from
57 initial expressions in the case of a build-in-place call.
59 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
61 * sem_eval.adb (Is_Null_Range): Retrieve the full view when called on a

77 (Is_Declaration_Other_Than_Renaming): Removed.
79 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
81 * sem_ch5.adb (Analyze_Assignment): Assignments to variables that act
82 as Part_Of consituents of single protected types are illegal when they
83 take place inside a protected function.
84 (Diagnose_Non_Variable_Lhs): Use Within_Function to check for an
86 (Is_Protected_Part_Of_Constituent): New routine.
87 (Within_Function): New routine.

95 * binde.adb, par-ch6.adb, par-ch9.adb, sem_ch12.adb, sem_ch13.adb:
98 2018-01-11 Justin Squirek <squirek@adacore.com>
100 * par-ch6.adb (Scan_Body_Or_Expression_Function): Add additional check
101 to make sure a given expression function is properly parenthesized.
103 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
105 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Check the
106 categorization of a subprogram body which does not complete a previous
109 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
111 * sem_ch10.adb (Check_Private_Child_Unit): Ensure that the enclosing
112 scope of package Ada is Standard.
114 2018-01-11 Ed Schonberg <schonberg@adacore.com>
116 * sem_ch13.adb (Replace_Type_Ref): Handle properly reference to a
117 subcomponent of the current entity when building the body for a dynamic
118 predicate function for a record with composite subcomponents.
120 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>

130 * exp_ch7.adb (Establish_Transient_Scope): Restructured. Delegate the
131 management of the secondary stack to an enclosing scope if there is no
132 suitable construct to wrap, and the transient scope was intended to
133 manage the secondary stack.
134 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
135 is a valid boundary for a transient expression which comes from the
136 statements of the alternative, otherwise alternatives cannot be
137 wrapped. Assignments of controlled objects which have controlled
138 actions suppressed now stop the traversal as there is no point in
139 looking for an enclosing construct. Add several N_xxx_Body choices to
140 the termination conditions for completeness.
141 * exp_ch7.ads (Establish_Transient_Scope): Update the parameter profile
142 and the associated comment on usage.
143 * exp_smem.adb (Add_Shared_Var_Lock_Procs): Update the call to
144 Establish_Transient_Scope.
145 (Add_Write_After): Update the call to Establish_Transient_Scope.
146 * sem_res.adb (Check_Initialization_Call): Removed.
147 (Resolve_Actuals): Account for additional cases where finalization
148 actions are required by utilizing predicate Needs_Finalization rather
150 (Resolve_Call): Type initialization procedures can now utilize
151 transient scopes to manage the secondary stack, thus preventing leaks
152 during initialization. Remove the previous kludgy algorithm which
153 attempts to manage the secondary stack at the object creation site.
155 2018-01-11 Jerome Lambourg <lambourg@adacore.com>

196 2018-01-11 Ed Schonberg <schonberg@adacore.com>
198 * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
199 formsl type corresponding to the actual fixed point type is private,
200 because in this case there can be no suspicious arithmetic operations
201 in the generic unless they reference a formal subprogram. Clarify
204 2018-01-11 Javier Miranda <miranda@adacore.com>
206 * exp_util.adb (Remove_Side_Effects): No action done for functions
207 returning class-wide types since it requires generating code using
208 'reference and the CCG target has no secondary stack.
209 * gnat1drv.adb: Disable building static dispatch tables when generating

228 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
230 * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
231 if it contains at least one component declaration employing a function
232 call returning on the secondary stack.

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

269 Default_Sec_Stack_Size.
270 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
271 limit check so that the integer index does not overflow. Check the
272 dynamic stack allocation does not cause the secondary stack pointer to
274 (SS_Info): Align colons.
275 (SS_Init): Cover the case when bootstraping with an old compiler that
276 does not set Default_SS_Size.
278 2018-01-11 Ed Schonberg <schonberg@adacore.com>
280 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
281 legality of an inherited operation that may require overriding, ignore
282 primitive_wrappers that correspond to explicit operations that override
283 an interface primitive.
284 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
285 operation to which the class-wide expression applies is a protected op.
286 with a primitive_wrapper, verify that the updated inherited expression
287 does not contain an internal call to a protected function. This
288 completes the implementation of AI12-0166.
290 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
292 * ali.adb: Document the remaining letters available for ALI lines.
293 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
294 * ali.ads: Update type With_Record. Field
295 Implicit_With_From_Instantiation is no longer in use. Add field
297 * csinfo.adb (CSinfo): Remove the setup for attribute
298 Implicit_With_From_Instantiation.
299 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
300 either implicitly or explicitly withed.
301 (Is_Implicit_With_Clause): New routine.
302 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
303 confusion with the with clause attribute by the same name.
304 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
305 * rtsfind.adb (Maybe_Add_With): Code cleanup.
306 * sem_ch8.adb (Present_System_Aux): Code cleanup.

311 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
312 instantiation are no longer marked as Implicit_With_From_Instantiation
313 because they are already marked as implicit.
314 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
315 which marks implicit with clauses as related to an instantiation.
316 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
317 (Parent_With): New routine.
318 (Set_Implicit_With_From_Instantiation): Removed.
319 (Set_Parent_With): New routine.
320 * sinfo.ads: Update the documentation of attribute Implicit_With.
321 Remove attribute Implicit_With_From_Instantiation along with
322 occurrences in nodes. Add attribute Parent_With along with occurrences
324 (Implicit_With_From_Instantiation): Removed along with pragma Inline.
325 (Parent_With): New routine along with pragma Inline.
326 (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.
327 (Set_Parent_With): New routine along with pragma Inline.

332 entity when the enclosing construct is a body.
334 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
336 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
337 Secondary_Stack_Size handling as a pragma is now generated for the
338 corresponding aspect instead of an attribute. Pragma expression is
339 relocated instead of evaluated. Discriminant of the corresponding
340 record type is referenced rather than the type discriminant.
341 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
342 Secondary_Stack_Size rep item checks to only look for the pragma rep.
343 * sem_ch13.adb (Analyze_One_Aspect): Transform
344 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
345 because the attribute does not have visibility on a task type's
346 discriminants when the type's definition is expanded.
347 (Analyze_Attribute_Definition_Clause): Remove handling of
348 Attribute_Secondary_Stack_Size.
349 * snames.adb-tmpl, snames.ads-tmpl: Remove

356 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
358 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
359 individual action because the action may denote a complex expression,
360 such as a case statement, which in turn may contain additional
363 2018-01-11 Ed Schonberg <schonberg@adacore.com>
365 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
366 analysis on a copy of the expression with a copy of the index variable,
367 because full expansion will rewrite construct into a loop with the
368 original loop variable.
369 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
370 expression is an iterated component association. Full analysis takes
371 place when construct is rewritten as a loop.
372 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
373 is not safe for in-place assignment.
374 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
375 entity with no homonym and no other entity in the scope.

401 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
402 for atomic access once the component size is taken into account and
403 also do it if the component type is Atomic or Volatile_Full_Access.
