1046 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
1047 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
1048 We need to analyze it as part of analyzing the block, so that if the

1052 of analyzing Elmt_Decl first was to catch the error of modifying it,
1053 which is illegal because it's a loop parameter. The above causes us to
1054 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
1055 it on the Element entity, so we end up with an E_Variable node with the

1077 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
1078 a package body that is a compilation unit may contain blocks that
1079 declare local subprograms. In Subprogram_Unnesting Mode such
1080 subprograms must be handled as nested inside the (implicit) elaboration
1081 procedure that executes that statement part. To handle properly uplevel
1082 references we construct that subprogram explicitly, to contain blocks
1083 and inner subprograms, The statement part of the compilation unit
1084 becomes a call to this subprogram. This is only done if blocks are
1085 present in the statement list of the body.

1156 tagged type. In such case, collecting the list of primitives we may
1157 find two equality primitives: one associated with the untagged private

1420 * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
1421 value when converting a float value to a fixed-point value. This is
1422 required for CCG because it handles fixed-point types by means of

1463 when bounds of fixed type are static, to remove some spuerfluous
1464 implicit conversions and provide an accurate result when converting
1465 back and forth between the fixed point type and a floating point type.

1475 replaced, if any; all callers changed.
1476 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
1477 constant with private view so we take the address of that entity.
1478 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
1479 any; all callers changed. Handle N_Indexed_Component like
1480 N_Attribute_Reference. Add N_Type_Conversion case.
1481 (Visit_Node): Indexed references can be uplevel if the type isn't
1483 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
1484 been relocated, set first_named pointer in original node as well.

1488 * exp_aggr.adb (Flatten): Copy tree of expression in a component
1489 association with a range or a set of discrete choices, rather than
1490 relocating the node. This avoids inconsistencies in the tree when
1491 handling nested subprograms with uplevel references for LLVM.

1578 (List_Entities): Do not output the linker section for record types,
1579 array types and variables.
1580 (Print_Expr): Factor out common processing for unary operators and
1581 special values. Adjust and reorder the various cases.
1582 (List_Object_Info): End with the linker section, if any.
1583 (List_Record_Info): Likewise.
1584 (List_Type_Info): Do not start with a blank line.

1598 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1600 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
1601 of a fixed point type and the parent is a multiplying operation,
1602 resolve the operand with its own type because the context will impose a
1603 resulting type on the result of the multiplication by means of
1604 approriate conversion.
1606 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1608 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
1609 the in-place initialization aggregate created for pragmas
1610 Initialize_Scalars or Normalize_Scalars is performed with checks
1613 2018-05-25 Arnaud Charlet <charlet@adacore.com>

1637 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1639 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
1640 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
1641 into three distring cases rather than in one loop which attempts to
1642 handle all three cases. This rewrite eliminates an issue where the last
1643 frame of the stack cannot be freed, thus causing the memory range of a
1644 new frame to approach the overflow point of the memory index type.
1645 Since the overflow is logically treated as a
1646 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
1647 (SS_Allocate_Static): New routine. The routine factorizes the static
1648 secondary stack-related code from the former SS_Allocate.

1658 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
1659 is created when the proper body of the stub is analyzed.
1660 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
1661 is the proper body of a subunit, the cloned body must be inserted in
1662 the declarative list that contains the stub.
1664 2018-05-25 Justin Squirek <squirek@adacore.com>
1666 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
1667 generate code for 6.5(8-10) so that we don't get an assertion error

1701 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
1702 Validate_Derived_Type_Instance, to verify that all interfaces
1703 implemented by the formal type are also implemented by the actual. The
1704 verification is complicated when an interface of the formal is declared
1705 in a generic unit and the actual is declared in an instance of it.
1706 There is currently no mechanism to relate an interface declared within
1707 a generic to the corresponding interface in an instance, so we must
1708 traverse the list of interfaces of the actual, looking for a name
1709 match, and verifying that that interface is declared in an instance.
1711 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
1713 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra

1780 in loops at the library level.
1782 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1784 * sem_ch13.adb (Build_Predicate_Functions): The predicate function
1785 declaration is inserted into the tree and analyzed at that point, so
1786 should not be reinserted when the body is constructed. Inside a
1787 generic, ensure that the body is not inserted twice in the tree.

2279 iteration of an Ada2012 loop is performed to determine the type of the

2945 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
2946 delegate the secondary stack management when there is no suitable
2947 transient context, and the transient scope was intended to manage the

2952 the comment on usage.
2953 (Find_Transient_Context): Change the initinte loop into a while loop.

3079 result of Get_Simple_Init_Value and pass the source location of the
3080 object declaration's object_definition.
3082 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3084 * exp_ch6.adb (Make_Build_In_Place_Call_In_Object_Declaration): Handle
3085 properly object declarations with initializations that are
3086 build-in-place function calls, when there is an address specification,
3087 either as an aspect specification or an explicit attribute
3088 specification clause, for the initialized object.
3089 * freeze.adb (Check_Address_Clause): Do not remove side-effects from
3090 initial expressions in the case of a build-in-place call.
3092 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
3094 * sem_eval.adb (Is_Null_Range): Retrieve the full view when called on a
3095 private (sub)type; refactor to avoid early return statement.
3096 (Not_Null_Range): Same as above.

3100 * freeze.adb (Freeze_Entity): Ensure that a Ghost type is not
3101 concurrent, nor effectively volatile.
3102 * ghost.adb (Check_Ghost_Type): New routine.
3103 * ghost.ads (Check_Ghost_Type): New routine.
3104 * sem_util.adb (Is_Declaration): Reimplemented. The routine can now
3105 consider specific subsets of declarations.
3106 (Is_Declaration_Other_Than_Renaming): Removed. Its functionality is
3107 replicated by Is_Declaration.
3108 * sem_util.ads (Is_Declaration): New parameter profile. Update the
3110 (Is_Declaration_Other_Than_Renaming): Removed.
3112 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3114 * sem_ch5.adb (Analyze_Assignment): Assignments to variables that act
3115 as Part_Of consituents of single protected types are illegal when they
3116 take place inside a protected function.
3117 (Diagnose_Non_Variable_Lhs): Use Within_Function to check for an
3119 (Is_Protected_Part_Of_Constituent): New routine.
3120 (Within_Function): New routine.

3124 Bump copyright notices to 2018.
3126 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3128 * binde.adb, par-ch6.adb, par-ch9.adb, sem_ch12.adb, sem_ch13.adb:
3131 2018-01-11 Justin Squirek <squirek@adacore.com>
3133 * par-ch6.adb (Scan_Body_Or_Expression_Function): Add additional check
3134 to make sure a given expression function is properly parenthesized.
3136 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3138 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Check the
3139 categorization of a subprogram body which does not complete a previous
3142 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3144 * sem_ch10.adb (Check_Private_Child_Unit): Ensure that the enclosing
3145 scope of package Ada is Standard.
3147 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3149 * sem_ch13.adb (Replace_Type_Ref): Handle properly reference to a
3150 subcomponent of the current entity when building the body for a dynamic
3151 predicate function for a record with composite subcomponents.
3153 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>

3161 (Make_Build_In_Place_Call_In_Object_Declaration): Update the call to
3162 Establish_Transient_Scope.
3163 * exp_ch7.adb (Establish_Transient_Scope): Restructured. Delegate the
3164 management of the secondary stack to an enclosing scope if there is no
3165 suitable construct to wrap, and the transient scope was intended to
3166 manage the secondary stack.
3167 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
3168 is a valid boundary for a transient expression which comes from the
3169 statements of the alternative, otherwise alternatives cannot be
3170 wrapped. Assignments of controlled objects which have controlled
3171 actions suppressed now stop the traversal as there is no point in
3172 looking for an enclosing construct. Add several N_xxx_Body choices to
3173 the termination conditions for completeness.
3174 * exp_ch7.ads (Establish_Transient_Scope): Update the parameter profile
3175 and the associated comment on usage.
3176 * exp_smem.adb (Add_Shared_Var_Lock_Procs): Update the call to
3177 Establish_Transient_Scope.
3178 (Add_Write_After): Update the call to Establish_Transient_Scope.
3179 * sem_res.adb (Check_Initialization_Call): Removed.
3180 (Resolve_Actuals): Account for additional cases where finalization
3181 actions are required by utilizing predicate Needs_Finalization rather
3183 (Resolve_Call): Type initialization procedures can now utilize
3184 transient scopes to manage the secondary stack, thus preventing leaks
3185 during initialization. Remove the previous kludgy algorithm which
3186 attempts to manage the secondary stack at the object creation site.
3188 2018-01-11 Jerome Lambourg <lambourg@adacore.com>
3190 * libgnat/g-soliop__qnx.ads: New.

3227 * gnat_rm.texi: Regenerate.
3229 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3231 * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
3232 formsl type corresponding to the actual fixed point type is private,
3233 because in this case there can be no suspicious arithmetic operations
3234 in the generic unless they reference a formal subprogram. Clarify
3237 2018-01-11 Javier Miranda <miranda@adacore.com>
3239 * exp_util.adb (Remove_Side_Effects): No action done for functions
3240 returning class-wide types since it requires generating code using
3241 'reference and the CCG target has no secondary stack.

3255 2018-01-11 Bob Duff <duff@adacore.com>
3257 * doc/gnat_ugn/gnat_utility_programs.rst: Rewrite gnatpp documentation
3258 to match what the Libadalang-based version does.
3259 * doc/gnat_ugn/about_this_guide.rst: Update reference.
3261 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3263 * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
3264 if it contains at least one component declaration employing a function
3265 call returning on the secondary stack.
3267 2018-01-11 Yannick Moy <moy@adacore.com>

3282 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3284 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
3285 has a delayed aspect which must be processed at the point the type is
3286 frozen. This mimics what is done when the predicate is provided by a

3302 Default_Sec_Stack_Size.
3303 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
3304 limit check so that the integer index does not overflow. Check the
3305 dynamic stack allocation does not cause the secondary stack pointer to
3307 (SS_Info): Align colons.
3308 (SS_Init): Cover the case when bootstraping with an old compiler that
3309 does not set Default_SS_Size.
3311 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3313 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
3314 legality of an inherited operation that may require overriding, ignore
3315 primitive_wrappers that correspond to explicit operations that override
3316 an interface primitive.
3317 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
3318 operation to which the class-wide expression applies is a protected op.
3319 with a primitive_wrapper, verify that the updated inherited expression
3320 does not contain an internal call to a protected function. This
3321 completes the implementation of AI12-0166.
3323 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3325 * ali.adb: Document the remaining letters available for ALI lines.
3326 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
3327 * ali.ads: Update type With_Record. Field
3328 Implicit_With_From_Instantiation is no longer in use. Add field
3330 * csinfo.adb (CSinfo): Remove the setup for attribute
3331 Implicit_With_From_Instantiation.
3332 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
3333 either implicitly or explicitly withed.
3334 (Is_Implicit_With_Clause): New routine.
3335 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
3336 confusion with the with clause attribute by the same name.
3337 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
3338 * rtsfind.adb (Maybe_Add_With): Code cleanup.
3339 * sem_ch8.adb (Present_System_Aux): Code cleanup.

3342 (Implicit_With_On_Parent): Mark the with clause as generated for a
3344 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
3345 instantiation are no longer marked as Implicit_With_From_Instantiation
3346 because they are already marked as implicit.
3347 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
3348 which marks implicit with clauses as related to an instantiation.
3349 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
3350 (Parent_With): New routine.
3351 (Set_Implicit_With_From_Instantiation): Removed.
3352 (Set_Parent_With): New routine.
3353 * sinfo.ads: Update the documentation of attribute Implicit_With.

3365 entity when the enclosing construct is a body.
3367 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
3369 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
3370 Secondary_Stack_Size handling as a pragma is now generated for the
3371 corresponding aspect instead of an attribute. Pragma expression is
3372 relocated instead of evaluated. Discriminant of the corresponding
3373 record type is referenced rather than the type discriminant.
3374 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
3375 Secondary_Stack_Size rep item checks to only look for the pragma rep.
3376 * sem_ch13.adb (Analyze_One_Aspect): Transform
3377 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
3378 because the attribute does not have visibility on a task type's

3381 Attribute_Secondary_Stack_Size.
3382 * snames.adb-tmpl, snames.ads-tmpl: Remove

3391 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
3392 individual action because the action may denote a complex expression,
3393 such as a case statement, which in turn may contain additional
3396 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3398 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
3399 analysis on a copy of the expression with a copy of the index variable,
3400 because full expansion will rewrite construct into a loop with the
3401 original loop variable.
3402 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
3403 expression is an iterated component association. Full analysis takes
3404 place when construct is rewritten as a loop.
3405 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
3406 is not safe for in-place assignment.
3407 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
3408 entity with no homonym and no other entity in the scope.

3434 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
3435 for atomic access once the component size is taken into account and
3436 also do it if the component type is Atomic or Volatile_Full_Access.
3438 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
