364 * sem_ch6.adb (Analyze_Subprogram_Body_Helper, Mask_Type):
365 Refine the handling of freezing types for expression functions
366 that are not completions, when analyzing the generated body for
367 the function: the body is inserted at the end of the enclosing

369 the same scope that have not been frozen yet.
371 2018-08-21 Ed Schonberg <schonberg@adacore.com>
373 * sem_ch6.adb: Remove Freeze_Expr_Types.

395 2018-08-21 Ed Schonberg <schonberg@adacore.com>
397 * sem_ch6.adb (Check_Synchronized_Overriding): The conformance
398 between an overriding protected operation and the overridden
399 abstract progenitor operation requires subtype conformance;
400 requiring equality of return types in the case of a function is
401 too restrictive and leads to spurious errors when the return
402 type is a generic actual.
404 2018-08-21 Ed Schonberg <schonberg@adacore.com>

428 parameters depending on their modes then analyse the body
430 (Check_Declaration): Consider both deep (including elementary
431 access) object declarations and normal variables. First check
432 whether the deep object is of Ownership Aspec True or not, then,
433 depending on its initialization, assign the appropriate state.
434 Check related to non access type variables deal with
435 initialization value permissions.

456 one expected (in the statement being analyzed).
457 (Process_Path): Given an operation and a current state, call
458 Perm_Error if there is any mismatch.
459 (Return_Declarations, Return_Globals, Return_The_Global): Check
460 the state of a given name at the end of the subprogram. These
461 procedures may change depending on how we shall finally deal
462 with globals and the rhs state in a move operation.
463 (Set_Perm_Extensions, Set_Perm_Prefixes_Borrow,
464 Set_Perm_Prefixes, Setup_Globals, Setup_Parameter_Or_Global,
465 Setup_Parameters): Set up the new states to the given node and
466 up and down the tree after an operation.

507 * exp_aggr.adb (Expand_Array_Aggregate): If the component type
508 is limited, the array must be constructed in place, so set flag
509 In_Place_Assign_OK_For_Declaration accordingly. This prevents
510 improper copying of an array of tasks during initialization.

532 synchronized type (For unnesting).
533 * itypes.ads, itypes.adb (Create_Itype): Ditto
534 * sem_ch3.adb (Constrain_Corresponding_Record): Generate a
535 unique name for the created subtype, because there may be

970 outside of a subprogram body. This case was previously handled during

972 we continued freezeing entities outside of the subprogram. Now, when
973 climbing the parents chain to locate the correct placement for the

988 with an additional parameter which is used to specify if during
989 preanalysis we are allowed to freeze entities. If the new parameter is
990 True then the subtree root node is marked as Must_Not_Freeze and no
991 entities are frozen during preanalysis.
992 (Preanalyze_And_Resolve): Invokes the internal version of
993 Preanalyze_And_Resolve without entity freezing.
994 (Preanalyze_With_Freezing_And_Resolve): Invokes the internal version of

1915 * exp_ch4.adb (Expand_Modular_Addition, Expand_Modular_Subtraction):
1916 Convert all operands of the generated code to Standard.Unsigned, to

2058 2018-05-30 Bob Duff <duff@adacore.com>
2060 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
2061 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
2062 We need to analyze it as part of analyzing the block, so that if the
2063 call to Element that initializes Elmt_Decl returns on the secondary
2064 stack, the block will ss_mark/ss_release. This block is inside the
2065 loop; we don't want to leak memory until the loop exits. The purpose
2066 of analyzing Elmt_Decl first was to catch the error of modifying it,
2067 which is illegal because it's a loop parameter. The above causes us to
2068 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
2069 it on the Element entity, so we end up with an E_Variable node with the
2071 * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.
2072 * sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop
2073 parameter not allowed" error if Is_Loop_Parameter.

2091 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
2092 a package body that is a compilation unit may contain blocks that
2093 declare local subprograms. In Subprogram_Unnesting Mode such
2094 subprograms must be handled as nested inside the (implicit) elaboration
2095 procedure that executes that statement part. To handle properly uplevel
2096 references we construct that subprogram explicitly, to contain blocks

2098 becomes a call to this subprogram. This is only done if blocks are
2099 present in the statement list of the body.

2434 * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
2435 value when converting a float value to a fixed-point value. This is

2490 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
2491 constant with private view so we take the address of that entity.
2492 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
2493 any; all callers changed. Handle N_Indexed_Component like
2494 N_Attribute_Reference. Add N_Type_Conversion case.

2502 * exp_aggr.adb (Flatten): Copy tree of expression in a component
2503 association with a range or a set of discrete choices, rather than

2612 2018-05-25 Ed Schonberg <schonberg@adacore.com>
2614 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
2615 of a fixed point type and the parent is a multiplying operation,
2616 resolve the operand with its own type because the context will impose a
2617 resulting type on the result of the multiplication by means of
2618 approriate conversion.
2620 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
2622 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
2623 the in-place initialization aggregate created for pragmas
2624 Initialize_Scalars or Normalize_Scalars is performed with checks

2651 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
2653 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
2654 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
2655 into three distring cases rather than in one loop which attempts to
2656 handle all three cases. This rewrite eliminates an issue where the last
2657 frame of the stack cannot be freed, thus causing the memory range of a
2658 new frame to approach the overflow point of the memory index type.
2659 Since the overflow is logically treated as a
2660 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
2661 (SS_Allocate_Static): New routine. The routine factorizes the static
2662 secondary stack-related code from the former SS_Allocate.
2664 2018-05-25 Sergey Rybin <rybin@adacore.com>

2672 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
2673 is created when the proper body of the stub is analyzed.
2674 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
2675 is the proper body of a subunit, the cloned body must be inserted in
2676 the declarative list that contains the stub.
2678 2018-05-25 Justin Squirek <squirek@adacore.com>
2680 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to

2715 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
2716 Validate_Derived_Type_Instance, to verify that all interfaces
2717 implemented by the formal type are also implemented by the actual. The
2718 verification is complicated when an interface of the formal is declared
2719 in a generic unit and the actual is declared in an instance of it.
2720 There is currently no mechanism to relate an interface declared within
2721 a generic to the corresponding interface in an instance, so we must
2722 traverse the list of interfaces of the actual, looking for a name
2723 match, and verifying that that interface is declared in an instance.
2725 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
2727 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra

3293 iteration of an Ada2012 loop is performed to determine the type of the

3959 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
3960 delegate the secondary stack management when there is no suitable
3961 transient context, and the transient scope was intended to manage the

4093 result of Get_Simple_Init_Value and pass the source location of the
4094 object declaration's object_definition.
4096 2018-01-11 Ed Schonberg <schonberg@adacore.com>
4098 * exp_ch6.adb (Make_Build_In_Place_Call_In_Object_Declaration): Handle
4099 properly object declarations with initializations that are
4100 build-in-place function calls, when there is an address specification,
4101 either as an aspect specification or an explicit attribute
4102 specification clause, for the initialized object.
4103 * freeze.adb (Check_Address_Clause): Do not remove side-effects from
4104 initial expressions in the case of a build-in-place call.
4106 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
4108 * sem_eval.adb (Is_Null_Range): Retrieve the full view when called on a
4109 private (sub)type; refactor to avoid early return statement.
4110 (Not_Null_Range): Same as above.
4112 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
4114 * freeze.adb (Freeze_Entity): Ensure that a Ghost type is not
4115 concurrent, nor effectively volatile.
4116 * ghost.adb (Check_Ghost_Type): New routine.
4117 * ghost.ads (Check_Ghost_Type): New routine.
4118 * sem_util.adb (Is_Declaration): Reimplemented. The routine can now
4119 consider specific subsets of declarations.
4120 (Is_Declaration_Other_Than_Renaming): Removed. Its functionality is
4121 replicated by Is_Declaration.
4122 * sem_util.ads (Is_Declaration): New parameter profile. Update the
4124 (Is_Declaration_Other_Than_Renaming): Removed.
4126 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
4128 * sem_ch5.adb (Analyze_Assignment): Assignments to variables that act
4129 as Part_Of consituents of single protected types are illegal when they
4130 take place inside a protected function.
4131 (Diagnose_Non_Variable_Lhs): Use Within_Function to check for an
4133 (Is_Protected_Part_Of_Constituent): New routine.
4134 (Within_Function): New routine.

4138 Bump copyright notices to 2018.
4140 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
4142 * binde.adb, par-ch6.adb, par-ch9.adb, sem_ch12.adb, sem_ch13.adb:
4145 2018-01-11 Justin Squirek <squirek@adacore.com>
4147 * par-ch6.adb (Scan_Body_Or_Expression_Function): Add additional check
4148 to make sure a given expression function is properly parenthesized.
4150 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
4152 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Check the
4153 categorization of a subprogram body which does not complete a previous
4156 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
4158 * sem_ch10.adb (Check_Private_Child_Unit): Ensure that the enclosing
4159 scope of package Ada is Standard.
4161 2018-01-11 Ed Schonberg <schonberg@adacore.com>
4163 * sem_ch13.adb (Replace_Type_Ref): Handle properly reference to a
4164 subcomponent of the current entity when building the body for a dynamic
4165 predicate function for a record with composite subcomponents.
4167 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>

4175 (Make_Build_In_Place_Call_In_Object_Declaration): Update the call to
4176 Establish_Transient_Scope.
4177 * exp_ch7.adb (Establish_Transient_Scope): Restructured. Delegate the
4178 management of the secondary stack to an enclosing scope if there is no
4179 suitable construct to wrap, and the transient scope was intended to
4180 manage the secondary stack.
4181 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
4182 is a valid boundary for a transient expression which comes from the
4183 statements of the alternative, otherwise alternatives cannot be
4184 wrapped. Assignments of controlled objects which have controlled
4185 actions suppressed now stop the traversal as there is no point in
4186 looking for an enclosing construct. Add several N_xxx_Body choices to
4187 the termination conditions for completeness.
4188 * exp_ch7.ads (Establish_Transient_Scope): Update the parameter profile
4189 and the associated comment on usage.
4190 * exp_smem.adb (Add_Shared_Var_Lock_Procs): Update the call to
4191 Establish_Transient_Scope.
4192 (Add_Write_After): Update the call to Establish_Transient_Scope.
4193 * sem_res.adb (Check_Initialization_Call): Removed.
4194 (Resolve_Actuals): Account for additional cases where finalization
4195 actions are required by utilizing predicate Needs_Finalization rather
4197 (Resolve_Call): Type initialization procedures can now utilize
4198 transient scopes to manage the secondary stack, thus preventing leaks
4199 during initialization. Remove the previous kludgy algorithm which
4200 attempts to manage the secondary stack at the object creation site.
4202 2018-01-11 Jerome Lambourg <lambourg@adacore.com>
4204 * libgnat/g-soliop__qnx.ads: New.

4241 * gnat_rm.texi: Regenerate.
4243 2018-01-11 Ed Schonberg <schonberg@adacore.com>
4245 * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
4246 formsl type corresponding to the actual fixed point type is private,
4247 because in this case there can be no suspicious arithmetic operations
4248 in the generic unless they reference a formal subprogram. Clarify
4251 2018-01-11 Javier Miranda <miranda@adacore.com>
4253 * exp_util.adb (Remove_Side_Effects): No action done for functions
4254 returning class-wide types since it requires generating code using
4255 'reference and the CCG target has no secondary stack.
4256 * gnat1drv.adb: Disable building static dispatch tables when generating

4269 2018-01-11 Bob Duff <duff@adacore.com>
4271 * doc/gnat_ugn/gnat_utility_programs.rst: Rewrite gnatpp documentation
4272 to match what the Libadalang-based version does.
4273 * doc/gnat_ugn/about_this_guide.rst: Update reference.
4275 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
4277 * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
4278 if it contains at least one component declaration employing a function
4279 call returning on the secondary stack.
4281 2018-01-11 Yannick Moy <moy@adacore.com>

4296 2018-01-11 Ed Schonberg <schonberg@adacore.com>
4298 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
4299 has a delayed aspect which must be processed at the point the type is
4300 frozen. This mimics what is done when the predicate is provided by a

4316 Default_Sec_Stack_Size.
4317 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
4318 limit check so that the integer index does not overflow. Check the
4319 dynamic stack allocation does not cause the secondary stack pointer to
4321 (SS_Info): Align colons.
4322 (SS_Init): Cover the case when bootstraping with an old compiler that
4323 does not set Default_SS_Size.
4325 2018-01-11 Ed Schonberg <schonberg@adacore.com>
4327 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
4328 legality of an inherited operation that may require overriding, ignore
4329 primitive_wrappers that correspond to explicit operations that override
4330 an interface primitive.
4331 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
4332 operation to which the class-wide expression applies is a protected op.
4333 with a primitive_wrapper, verify that the updated inherited expression
4334 does not contain an internal call to a protected function. This
4335 completes the implementation of AI12-0166.
4337 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
4339 * ali.adb: Document the remaining letters available for ALI lines.
4340 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
4341 * ali.ads: Update type With_Record. Field
4342 Implicit_With_From_Instantiation is no longer in use. Add field
4344 * csinfo.adb (CSinfo): Remove the setup for attribute
4345 Implicit_With_From_Instantiation.
4346 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
4347 either implicitly or explicitly withed.
4348 (Is_Implicit_With_Clause): New routine.
4349 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
4350 confusion with the with clause attribute by the same name.
4351 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
4352 * rtsfind.adb (Maybe_Add_With): Code cleanup.
4353 * sem_ch8.adb (Present_System_Aux): Code cleanup.

4356 (Implicit_With_On_Parent): Mark the with clause as generated for a
4358 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
4359 instantiation are no longer marked as Implicit_With_From_Instantiation
4360 because they are already marked as implicit.
4361 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
4362 which marks implicit with clauses as related to an instantiation.
4363 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
4364 (Parent_With): New routine.
4365 (Set_Implicit_With_From_Instantiation): Removed.
4366 (Set_Parent_With): New routine.
4367 * sinfo.ads: Update the documentation of attribute Implicit_With.

4379 entity when the enclosing construct is a body.
4381 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
4383 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
4384 Secondary_Stack_Size handling as a pragma is now generated for the
4385 corresponding aspect instead of an attribute. Pragma expression is
4386 relocated instead of evaluated. Discriminant of the corresponding
4387 record type is referenced rather than the type discriminant.
4388 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
4389 Secondary_Stack_Size rep item checks to only look for the pragma rep.
4390 * sem_ch13.adb (Analyze_One_Aspect): Transform
4391 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
4392 because the attribute does not have visibility on a task type's

4394 (Analyze_Attribute_Definition_Clause): Remove handling of
4395 Attribute_Secondary_Stack_Size.
4396 * snames.adb-tmpl, snames.ads-tmpl: Remove

4405 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
4406 individual action because the action may denote a complex expression,
4407 such as a case statement, which in turn may contain additional
4410 2018-01-11 Ed Schonberg <schonberg@adacore.com>
4412 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
4413 analysis on a copy of the expression with a copy of the index variable,
4414 because full expansion will rewrite construct into a loop with the
4415 original loop variable.
4416 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
4417 expression is an iterated component association. Full analysis takes
4418 place when construct is rewritten as a loop.
4419 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
4420 is not safe for in-place assignment.
4421 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
4422 entity with no homonym and no other entity in the scope.
4424 2018-01-11 Justin Squirek <squirek@adacore.com>

4432 entity of the generated invariant procedure in order to construct a
4433 proper entity chain.

4446 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
4448 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
4449 for atomic access once the component size is taken into account and
4450 also do it if the component type is Atomic or Volatile_Full_Access.
4452 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
