1064 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
1065 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
1066 We need to analyze it as part of analyzing the block, so that if the
1067 call to Element that initializes Elmt_Decl returns on the secondary
1068 stack, the block will ss_mark/ss_release. This block is inside the
1069 loop; we don't want to leak memory until the loop exits. The purpose
1070 of analyzing Elmt_Decl first was to catch the error of modifying it,
1071 which is illegal because it's a loop parameter. The above causes us to
1072 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
1073 it on the Element entity, so we end up with an E_Variable node with the
1075 * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.
1076 * sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop
1077 parameter not allowed" error if Is_Loop_Parameter.
1078 * sem_util.adb (Is_Variable): Return False if Is_Loop_Parameter, to
1079 trigger the call to Diagnose_Non_Variable_Lhs.

1095 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
1096 a package body that is a compilation unit may contain blocks that
1097 declare local subprograms. In Subprogram_Unnesting Mode such
1098 subprograms must be handled as nested inside the (implicit) elaboration
1099 procedure that executes that statement part. To handle properly uplevel
1100 references we construct that subprogram explicitly, to contain blocks
1101 and inner subprograms, The statement part of the compilation unit
1102 becomes a call to this subprogram. This is only done if blocks are
1103 present in the statement list of the body.

1175 find two equality primitives: one associated with the untagged private

1438 * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
1439 value when converting a float value to a fixed-point value. This is
1440 required for CCG because it handles fixed-point types by means of

1481 when bounds of fixed type are static, to remove some spuerfluous
1482 implicit conversions and provide an accurate result when converting
1483 back and forth between the fixed point type and a floating point type.

1494 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
1495 constant with private view so we take the address of that entity.
1496 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
1497 any; all callers changed. Handle N_Indexed_Component like
1498 N_Attribute_Reference. Add N_Type_Conversion case.
1499 (Visit_Node): Indexed references can be uplevel if the type isn't
1501 (Unnest_Subprograms): Don't rewrite if no reference given. If call has

1506 * exp_aggr.adb (Flatten): Copy tree of expression in a component
1507 association with a range or a set of discrete choices, rather than

1575 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
1576 includes a call to function to which it applies. This may mean an
1577 omission of an attribute reference 'Result, in particular if the
1578 function is pqrameterless.

1596 (List_Entities): Do not output the linker section for record types,
1597 array types and variables.
1598 (Print_Expr): Factor out common processing for unary operators and
1599 special values. Adjust and reorder the various cases.
1600 (List_Object_Info): End with the linker section, if any.
1601 (List_Record_Info): Likewise.

1616 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1618 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
1619 of a fixed point type and the parent is a multiplying operation,
1620 resolve the operand with its own type because the context will impose a
1621 resulting type on the result of the multiplication by means of
1622 approriate conversion.
1624 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1626 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
1627 the in-place initialization aggregate created for pragmas
1628 Initialize_Scalars or Normalize_Scalars is performed with checks

1655 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1657 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
1658 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
1659 into three distring cases rather than in one loop which attempts to
1660 handle all three cases. This rewrite eliminates an issue where the last
1661 frame of the stack cannot be freed, thus causing the memory range of a
1662 new frame to approach the overflow point of the memory index type.
1663 Since the overflow is logically treated as a
1664 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
1665 (SS_Allocate_Static): New routine. The routine factorizes the static
1666 secondary stack-related code from the former SS_Allocate.

1676 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
1677 is created when the proper body of the stub is analyzed.
1678 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
1679 is the proper body of a subunit, the cloned body must be inserted in
1680 the declarative list that contains the stub.
1682 2018-05-25 Justin Squirek <squirek@adacore.com>
1684 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
1685 generate code for 6.5(8-10) so that we don't get an assertion error
1686 when dealing with an incomplete return type.
1688 2018-05-25 Arnaud Charlet <charlet@adacore.com>

1717 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1719 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
1720 Validate_Derived_Type_Instance, to verify that all interfaces
1721 implemented by the formal type are also implemented by the actual. The
1722 verification is complicated when an interface of the formal is declared
1723 in a generic unit and the actual is declared in an instance of it.
1724 There is currently no mechanism to relate an interface declared within
1725 a generic to the corresponding interface in an instance, so we must
1726 traverse the list of interfaces of the actual, looking for a name
1727 match, and verifying that that interface is declared in an instance.
1729 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
1731 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra
1732 assertions; replace function versions of Next_Formal/Next_Actual with

1802 * sem_ch13.adb (Build_Predicate_Functions): The predicate function
1803 declaration is inserted into the tree and analyzed at that point, so
1804 should not be reinserted when the body is constructed. Inside a
1805 generic, ensure that the body is not inserted twice in the tree.

2297 iteration of an Ada2012 loop is performed to determine the type of the

3102 * exp_ch6.adb (Make_Build_In_Place_Call_In_Object_Declaration): Handle
3103 properly object declarations with initializations that are
3104 build-in-place function calls, when there is an address specification,
3105 either as an aspect specification or an explicit attribute
3106 specification clause, for the initialized object.
3107 * freeze.adb (Check_Address_Clause): Do not remove side-effects from

3110 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
3112 * sem_eval.adb (Is_Null_Range): Retrieve the full view when called on a
3113 private (sub)type; refactor to avoid early return statement.

3125 replicated by Is_Declaration.
3126 * sem_util.ads (Is_Declaration): New parameter profile. Update the

3163 scope of package Ada is Standard.
3165 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3167 * sem_ch13.adb (Replace_Type_Ref): Handle properly reference to a
3168 subcomponent of the current entity when building the body for a dynamic
3169 predicate function for a record with composite subcomponents.

3181 * exp_ch7.adb (Establish_Transient_Scope): Restructured. Delegate the
3182 management of the secondary stack to an enclosing scope if there is no
3183 suitable construct to wrap, and the transient scope was intended to
3184 manage the secondary stack.
3185 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
3186 is a valid boundary for a transient expression which comes from the
3187 statements of the alternative, otherwise alternatives cannot be
3188 wrapped. Assignments of controlled objects which have controlled
3189 actions suppressed now stop the traversal as there is no point in
3190 looking for an enclosing construct. Add several N_xxx_Body choices to
3191 the termination conditions for completeness.
3192 * exp_ch7.ads (Establish_Transient_Scope): Update the parameter profile
3193 and the associated comment on usage.
3194 * exp_smem.adb (Add_Shared_Var_Lock_Procs): Update the call to
3195 Establish_Transient_Scope.

3198 (Resolve_Actuals): Account for additional cases where finalization
3199 actions are required by utilizing predicate Needs_Finalization rather
3201 (Resolve_Call): Type initialization procedures can now utilize
3202 transient scopes to manage the secondary stack, thus preventing leaks
3203 during initialization. Remove the previous kludgy algorithm which
3204 attempts to manage the secondary stack at the object creation site.
3206 2018-01-11 Jerome Lambourg <lambourg@adacore.com>

3247 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3249 * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
3250 formsl type corresponding to the actual fixed point type is private,
3251 because in this case there can be no suspicious arithmetic operations
3252 in the generic unless they reference a formal subprogram. Clarify
3255 2018-01-11 Javier Miranda <miranda@adacore.com>
3257 * exp_util.adb (Remove_Side_Effects): No action done for functions
3258 returning class-wide types since it requires generating code using
3259 'reference and the CCG target has no secondary stack.

3279 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3281 * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
3282 if it contains at least one component declaration employing a function
3283 call returning on the secondary stack.

3302 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
3303 has a delayed aspect which must be processed at the point the type is

3327 does not set Default_SS_Size.
3329 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3331 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
3332 legality of an inherited operation that may require overriding, ignore
3333 primitive_wrappers that correspond to explicit operations that override
3334 an interface primitive.
3335 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
3336 operation to which the class-wide expression applies is a protected op.
3337 with a primitive_wrapper, verify that the updated inherited expression
3338 does not contain an internal call to a protected function. This
3339 completes the implementation of AI12-0166.
3341 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3343 * ali.adb: Document the remaining letters available for ALI lines.
3344 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
3345 * ali.ads: Update type With_Record. Field
3346 Implicit_With_From_Instantiation is no longer in use. Add field
3348 * csinfo.adb (CSinfo): Remove the setup for attribute
3349 Implicit_With_From_Instantiation.
3350 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
3351 either implicitly or explicitly withed.
3352 (Is_Implicit_With_Clause): New routine.
3353 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
3354 confusion with the with clause attribute by the same name.
3355 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
3356 * rtsfind.adb (Maybe_Add_With): Code cleanup.

3360 (Implicit_With_On_Parent): Mark the with clause as generated for a
3362 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
3363 instantiation are no longer marked as Implicit_With_From_Instantiation
3364 because they are already marked as implicit.
3365 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
3366 which marks implicit with clauses as related to an instantiation.
3367 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
3368 (Parent_With): New routine.
3369 (Set_Implicit_With_From_Instantiation): Removed.
3370 (Set_Parent_With): New routine.

3387 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
3388 Secondary_Stack_Size handling as a pragma is now generated for the
3389 corresponding aspect instead of an attribute. Pragma expression is
3390 relocated instead of evaluated. Discriminant of the corresponding
3391 record type is referenced rather than the type discriminant.
3392 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
3393 Secondary_Stack_Size rep item checks to only look for the pragma rep.
3394 * sem_ch13.adb (Analyze_One_Aspect): Transform
3395 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
3396 because the attribute does not have visibility on a task type's

3399 Attribute_Secondary_Stack_Size.
3400 * snames.adb-tmpl, snames.ads-tmpl: Remove

3409 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
3410 individual action because the action may denote a complex expression,
3411 such as a case statement, which in turn may contain additional

3416 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
3417 analysis on a copy of the expression with a copy of the index variable,
3418 because full expansion will rewrite construct into a loop with the
3419 original loop variable.
3420 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
3421 expression is an iterated component association. Full analysis takes
3422 place when construct is rewritten as a loop.
3423 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
3424 is not safe for in-place assignment.
3425 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated

3453 for atomic access once the component size is taken into account and
3454 also do it if the component type is Atomic or Volatile_Full_Access.
