1059 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
1060 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
1061 We need to analyze it as part of analyzing the block, so that if the
1062 call to Element that initializes Elmt_Decl returns on the secondary
1063 stack, the block will ss_mark/ss_release. This block is inside the
1064 loop; we don't want to leak memory until the loop exits. The purpose
1065 of analyzing Elmt_Decl first was to catch the error of modifying it,
1066 which is illegal because it's a loop parameter. The above causes us to
1067 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set

1072 parameter not allowed" error if Is_Loop_Parameter.
1073 * sem_util.adb (Is_Variable): Return False if Is_Loop_Parameter, to
1074 trigger the call to Diagnose_Non_Variable_Lhs.

1090 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
1091 a package body that is a compilation unit may contain blocks that
1092 declare local subprograms. In Subprogram_Unnesting Mode such
1093 subprograms must be handled as nested inside the (implicit) elaboration
1094 procedure that executes that statement part. To handle properly uplevel
1095 references we construct that subprogram explicitly, to contain blocks
1096 and inner subprograms, The statement part of the compilation unit
1097 becomes a call to this subprogram. This is only done if blocks are
1098 present in the statement list of the body.

1433 * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
1434 value when converting a float value to a fixed-point value. This is
1435 required for CCG because it handles fixed-point types by means of

1476 when bounds of fixed type are static, to remove some spuerfluous
1477 implicit conversions and provide an accurate result when converting
1478 back and forth between the fixed point type and a floating point type.

1489 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
1490 constant with private view so we take the address of that entity.
1491 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
1492 any; all callers changed. Handle N_Indexed_Component like
1493 N_Attribute_Reference. Add N_Type_Conversion case.
1494 (Visit_Node): Indexed references can be uplevel if the type isn't
1496 (Unnest_Subprograms): Don't rewrite if no reference given. If call has

1501 * exp_aggr.adb (Flatten): Copy tree of expression in a component
1502 association with a range or a set of discrete choices, rather than

1591 (List_Entities): Do not output the linker section for record types,
1592 array types and variables.
1593 (Print_Expr): Factor out common processing for unary operators and
1594 special values. Adjust and reorder the various cases.
1595 (List_Object_Info): End with the linker section, if any.

1611 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1613 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
1614 of a fixed point type and the parent is a multiplying operation,
1615 resolve the operand with its own type because the context will impose a
1616 resulting type on the result of the multiplication by means of
1617 approriate conversion.
1619 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1621 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
1622 the in-place initialization aggregate created for pragmas
1623 Initialize_Scalars or Normalize_Scalars is performed with checks

1650 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1652 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
1653 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
1654 into three distring cases rather than in one loop which attempts to
1655 handle all three cases. This rewrite eliminates an issue where the last
1656 frame of the stack cannot be freed, thus causing the memory range of a
1657 new frame to approach the overflow point of the memory index type.
1658 Since the overflow is logically treated as a
1659 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
1660 (SS_Allocate_Static): New routine. The routine factorizes the static
1661 secondary stack-related code from the former SS_Allocate.

1671 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
1672 is created when the proper body of the stub is analyzed.
1673 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
1674 is the proper body of a subunit, the cloned body must be inserted in
1675 the declarative list that contains the stub.
1677 2018-05-25 Justin Squirek <squirek@adacore.com>
1679 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
1680 generate code for 6.5(8-10) so that we don't get an assertion error

1714 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
1715 Validate_Derived_Type_Instance, to verify that all interfaces
1716 implemented by the formal type are also implemented by the actual. The
1717 verification is complicated when an interface of the formal is declared
1718 in a generic unit and the actual is declared in an instance of it.
1719 There is currently no mechanism to relate an interface declared within
1720 a generic to the corresponding interface in an instance, so we must
1721 traverse the list of interfaces of the actual, looking for a name
1722 match, and verifying that that interface is declared in an instance.
1724 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
1726 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra
1727 assertions; replace function versions of Next_Formal/Next_Actual with

1793 in loops at the library level.

1797 * sem_ch13.adb (Build_Predicate_Functions): The predicate function
1798 declaration is inserted into the tree and analyzed at that point, so
1799 should not be reinserted when the body is constructed. Inside a
1800 generic, ensure that the body is not inserted twice in the tree.

2292 iteration of an Ada2012 loop is performed to determine the type of the

2958 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
2959 delegate the secondary stack management when there is no suitable
2960 transient context, and the transient scope was intended to manage the

3097 * exp_ch6.adb (Make_Build_In_Place_Call_In_Object_Declaration): Handle
3098 properly object declarations with initializations that are
3099 build-in-place function calls, when there is an address specification,
3100 either as an aspect specification or an explicit attribute
3101 specification clause, for the initialized object.
3102 * freeze.adb (Check_Address_Clause): Do not remove side-effects from
3103 initial expressions in the case of a build-in-place call.
3105 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
3107 * sem_eval.adb (Is_Null_Range): Retrieve the full view when called on a
3108 private (sub)type; refactor to avoid early return statement.

3117 * sem_util.adb (Is_Declaration): Reimplemented. The routine can now
3118 consider specific subsets of declarations.
3119 (Is_Declaration_Other_Than_Renaming): Removed. Its functionality is
3120 replicated by Is_Declaration.
3121 * sem_util.ads (Is_Declaration): New parameter profile. Update the

3141 * binde.adb, par-ch6.adb, par-ch9.adb, sem_ch12.adb, sem_ch13.adb:
3144 2018-01-11 Justin Squirek <squirek@adacore.com>
3146 * par-ch6.adb (Scan_Body_Or_Expression_Function): Add additional check
3147 to make sure a given expression function is properly parenthesized.

3158 scope of package Ada is Standard.
3160 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3162 * sem_ch13.adb (Replace_Type_Ref): Handle properly reference to a
3163 subcomponent of the current entity when building the body for a dynamic
3164 predicate function for a record with composite subcomponents.

3174 (Make_Build_In_Place_Call_In_Object_Declaration): Update the call to
3175 Establish_Transient_Scope.
3176 * exp_ch7.adb (Establish_Transient_Scope): Restructured. Delegate the
3177 management of the secondary stack to an enclosing scope if there is no
3178 suitable construct to wrap, and the transient scope was intended to
3179 manage the secondary stack.
3180 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
3181 is a valid boundary for a transient expression which comes from the
3182 statements of the alternative, otherwise alternatives cannot be
3183 wrapped. Assignments of controlled objects which have controlled
3184 actions suppressed now stop the traversal as there is no point in
3185 looking for an enclosing construct. Add several N_xxx_Body choices to
3186 the termination conditions for completeness.
3187 * exp_ch7.ads (Establish_Transient_Scope): Update the parameter profile
3188 and the associated comment on usage.
3189 * exp_smem.adb (Add_Shared_Var_Lock_Procs): Update the call to
3190 Establish_Transient_Scope.
3191 (Add_Write_After): Update the call to Establish_Transient_Scope.
3192 * sem_res.adb (Check_Initialization_Call): Removed.
3193 (Resolve_Actuals): Account for additional cases where finalization
3194 actions are required by utilizing predicate Needs_Finalization rather
3196 (Resolve_Call): Type initialization procedures can now utilize
3197 transient scopes to manage the secondary stack, thus preventing leaks
3198 during initialization. Remove the previous kludgy algorithm which
3199 attempts to manage the secondary stack at the object creation site.
3201 2018-01-11 Jerome Lambourg <lambourg@adacore.com>
3203 * libgnat/g-soliop__qnx.ads: New.

3242 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3244 * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
3245 formsl type corresponding to the actual fixed point type is private,
3246 because in this case there can be no suspicious arithmetic operations
3247 in the generic unless they reference a formal subprogram. Clarify
3250 2018-01-11 Javier Miranda <miranda@adacore.com>
3252 * exp_util.adb (Remove_Side_Effects): No action done for functions
3253 returning class-wide types since it requires generating code using
3254 'reference and the CCG target has no secondary stack.

3274 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3276 * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
3277 if it contains at least one component declaration employing a function
3278 call returning on the secondary stack.

3297 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
3298 has a delayed aspect which must be processed at the point the type is
3299 frozen. This mimics what is done when the predicate is provided by a

3315 Default_Sec_Stack_Size.
3316 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack

3321 (SS_Init): Cover the case when bootstraping with an old compiler that
3322 does not set Default_SS_Size.
3324 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3326 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
3327 legality of an inherited operation that may require overriding, ignore
3328 primitive_wrappers that correspond to explicit operations that override
3329 an interface primitive.
3330 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
3331 operation to which the class-wide expression applies is a protected op.
3332 with a primitive_wrapper, verify that the updated inherited expression
3333 does not contain an internal call to a protected function. This
3334 completes the implementation of AI12-0166.
3336 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3338 * ali.adb: Document the remaining letters available for ALI lines.
3339 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
3340 * ali.ads: Update type With_Record. Field
3341 Implicit_With_From_Instantiation is no longer in use. Add field
3343 * csinfo.adb (CSinfo): Remove the setup for attribute
3344 Implicit_With_From_Instantiation.
3345 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
3346 either implicitly or explicitly withed.
3347 (Is_Implicit_With_Clause): New routine.
3348 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
3349 confusion with the with clause attribute by the same name.
3350 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
3351 * rtsfind.adb (Maybe_Add_With): Code cleanup.

3355 (Implicit_With_On_Parent): Mark the with clause as generated for a
3357 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
3358 instantiation are no longer marked as Implicit_With_From_Instantiation
3359 because they are already marked as implicit.
3360 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
3361 which marks implicit with clauses as related to an instantiation.
3362 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
3363 (Parent_With): New routine.
3364 (Set_Implicit_With_From_Instantiation): Removed.
3365 (Set_Parent_With): New routine.

3382 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
3383 Secondary_Stack_Size handling as a pragma is now generated for the
3384 corresponding aspect instead of an attribute. Pragma expression is
3385 relocated instead of evaluated. Discriminant of the corresponding
3386 record type is referenced rather than the type discriminant.
3387 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
3388 Secondary_Stack_Size rep item checks to only look for the pragma rep.
3389 * sem_ch13.adb (Analyze_One_Aspect): Transform
3390 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
3391 because the attribute does not have visibility on a task type's

3394 Attribute_Secondary_Stack_Size.
3395 * snames.adb-tmpl, snames.ads-tmpl: Remove

3404 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
3405 individual action because the action may denote a complex expression,
3406 such as a case statement, which in turn may contain additional

3411 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
3412 analysis on a copy of the expression with a copy of the index variable,
3413 because full expansion will rewrite construct into a loop with the
3414 original loop variable.
3415 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
3416 expression is an iterated component association. Full analysis takes
3417 place when construct is rewritten as a loop.
3418 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
3419 is not safe for in-place assignment.
3420 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated

3448 for atomic access once the component size is taken into account and
3449 also do it if the component type is Atomic or Volatile_Full_Access.
