1035 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
1036 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
1037 We need to analyze it as part of analyzing the block, so that if the
1038 call to Element that initializes Elmt_Decl returns on the secondary
1039 stack, the block will ss_mark/ss_release. This block is inside the

1041 of analyzing Elmt_Decl first was to catch the error of modifying it,
1042 which is illegal because it's a loop parameter. The above causes us to
1043 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
1044 it on the Element entity, so we end up with an E_Variable node with the

1068 declare local subprograms. In Subprogram_Unnesting Mode such
1069 subprograms must be handled as nested inside the (implicit) elaboration
1070 procedure that executes that statement part. To handle properly uplevel
1071 references we construct that subprogram explicitly, to contain blocks
1072 and inner subprograms, The statement part of the compilation unit
1073 becomes a call to this subprogram. This is only done if blocks are
1074 present in the statement list of the body.

1409 * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
1410 value when converting a float value to a fixed-point value. This is
1411 required for CCG because it handles fixed-point types by means of

1464 replaced, if any; all callers changed.
1465 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
1466 constant with private view so we take the address of that entity.
1467 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
1468 any; all callers changed. Handle N_Indexed_Component like
1469 N_Attribute_Reference. Add N_Type_Conversion case.
1470 (Visit_Node): Indexed references can be uplevel if the type isn't
1472 (Unnest_Subprograms): Don't rewrite if no reference given. If call has

1477 * exp_aggr.adb (Flatten): Copy tree of expression in a component
1478 association with a range or a set of discrete choices, rather than
1479 relocating the node. This avoids inconsistencies in the tree when

1570 special values. Adjust and reorder the various cases.

1587 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1589 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
1590 of a fixed point type and the parent is a multiplying operation,
1591 resolve the operand with its own type because the context will impose a
1592 resulting type on the result of the multiplication by means of
1593 approriate conversion.
1595 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1597 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
1598 the in-place initialization aggregate created for pragmas
1599 Initialize_Scalars or Normalize_Scalars is performed with checks

1626 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1628 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
1629 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
1630 into three distring cases rather than in one loop which attempts to
1631 handle all three cases. This rewrite eliminates an issue where the last
1632 frame of the stack cannot be freed, thus causing the memory range of a
1633 new frame to approach the overflow point of the memory index type.
1634 Since the overflow is logically treated as a
1635 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
1636 (SS_Allocate_Static): New routine. The routine factorizes the static
1637 secondary stack-related code from the former SS_Allocate.
1639 2018-05-25 Sergey Rybin <rybin@adacore.com>

1647 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
1648 is created when the proper body of the stub is analyzed.
1649 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
1650 is the proper body of a subunit, the cloned body must be inserted in
1651 the declarative list that contains the stub.
1653 2018-05-25 Justin Squirek <squirek@adacore.com>
1655 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to

1690 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
1691 Validate_Derived_Type_Instance, to verify that all interfaces
1692 implemented by the formal type are also implemented by the actual. The
1693 verification is complicated when an interface of the formal is declared
1694 in a generic unit and the actual is declared in an instance of it.
1695 There is currently no mechanism to relate an interface declared within
1696 a generic to the corresponding interface in an instance, so we must
1697 traverse the list of interfaces of the actual, looking for a name
1698 match, and verifying that that interface is declared in an instance.
1700 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
1702 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra

2268 iteration of an Ada2012 loop is performed to determine the type of the

2934 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
2935 delegate the secondary stack management when there is no suitable
2936 transient context, and the transient scope was intended to manage the

3067 * exp_ch3.adb (Default_Initialize_Object): Call New_Copy_Tree on the
3068 result of Get_Simple_Init_Value and pass the source location of the
3069 object declaration's object_definition.
3071 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3073 * exp_ch6.adb (Make_Build_In_Place_Call_In_Object_Declaration): Handle
3074 properly object declarations with initializations that are
3075 build-in-place function calls, when there is an address specification,
3076 either as an aspect specification or an explicit attribute
3077 specification clause, for the initialized object.
3078 * freeze.adb (Check_Address_Clause): Do not remove side-effects from
3079 initial expressions in the case of a build-in-place call.
3081 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
3083 * sem_eval.adb (Is_Null_Range): Retrieve the full view when called on a
3084 private (sub)type; refactor to avoid early return statement.
3085 (Not_Null_Range): Same as above.
3087 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3089 * freeze.adb (Freeze_Entity): Ensure that a Ghost type is not
3090 concurrent, nor effectively volatile.
3091 * ghost.adb (Check_Ghost_Type): New routine.
3092 * ghost.ads (Check_Ghost_Type): New routine.
3093 * sem_util.adb (Is_Declaration): Reimplemented. The routine can now
3094 consider specific subsets of declarations.
3095 (Is_Declaration_Other_Than_Renaming): Removed. Its functionality is
3096 replicated by Is_Declaration.
3097 * sem_util.ads (Is_Declaration): New parameter profile. Update the
3099 (Is_Declaration_Other_Than_Renaming): Removed.
3101 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3103 * sem_ch5.adb (Analyze_Assignment): Assignments to variables that act
3104 as Part_Of consituents of single protected types are illegal when they
3105 take place inside a protected function.
3106 (Diagnose_Non_Variable_Lhs): Use Within_Function to check for an
3108 (Is_Protected_Part_Of_Constituent): New routine.
3109 (Within_Function): New routine.
3111 2018-01-11 Arnaud Charlet <charlet@adacore.com>
3113 Bump copyright notices to 2018.
3115 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3117 * binde.adb, par-ch6.adb, par-ch9.adb, sem_ch12.adb, sem_ch13.adb:
3120 2018-01-11 Justin Squirek <squirek@adacore.com>
3122 * par-ch6.adb (Scan_Body_Or_Expression_Function): Add additional check
3123 to make sure a given expression function is properly parenthesized.
3125 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3127 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Check the
3128 categorization of a subprogram body which does not complete a previous
3131 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3133 * sem_ch10.adb (Check_Private_Child_Unit): Ensure that the enclosing
3134 scope of package Ada is Standard.
3136 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3138 * sem_ch13.adb (Replace_Type_Ref): Handle properly reference to a
3139 subcomponent of the current entity when building the body for a dynamic
3140 predicate function for a record with composite subcomponents.
3142 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>

3150 (Make_Build_In_Place_Call_In_Object_Declaration): Update the call to
3151 Establish_Transient_Scope.
3152 * exp_ch7.adb (Establish_Transient_Scope): Restructured. Delegate the
3153 management of the secondary stack to an enclosing scope if there is no
3154 suitable construct to wrap, and the transient scope was intended to
3155 manage the secondary stack.
3156 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
3157 is a valid boundary for a transient expression which comes from the
3158 statements of the alternative, otherwise alternatives cannot be
3159 wrapped. Assignments of controlled objects which have controlled
3160 actions suppressed now stop the traversal as there is no point in
3161 looking for an enclosing construct. Add several N_xxx_Body choices to
3162 the termination conditions for completeness.
3163 * exp_ch7.ads (Establish_Transient_Scope): Update the parameter profile
3164 and the associated comment on usage.
3165 * exp_smem.adb (Add_Shared_Var_Lock_Procs): Update the call to
3166 Establish_Transient_Scope.
3167 (Add_Write_After): Update the call to Establish_Transient_Scope.
3168 * sem_res.adb (Check_Initialization_Call): Removed.
3169 (Resolve_Actuals): Account for additional cases where finalization
3170 actions are required by utilizing predicate Needs_Finalization rather
3172 (Resolve_Call): Type initialization procedures can now utilize
3173 transient scopes to manage the secondary stack, thus preventing leaks
3174 during initialization. Remove the previous kludgy algorithm which
3175 attempts to manage the secondary stack at the object creation site.
3177 2018-01-11 Jerome Lambourg <lambourg@adacore.com>
3179 * libgnat/g-soliop__qnx.ads: New.

3216 * gnat_rm.texi: Regenerate.
3218 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3220 * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
3221 formsl type corresponding to the actual fixed point type is private,
3222 because in this case there can be no suspicious arithmetic operations
3223 in the generic unless they reference a formal subprogram. Clarify
3226 2018-01-11 Javier Miranda <miranda@adacore.com>
3228 * exp_util.adb (Remove_Side_Effects): No action done for functions
3229 returning class-wide types since it requires generating code using
3230 'reference and the CCG target has no secondary stack.
3231 * gnat1drv.adb: Disable building static dispatch tables when generating
3234 2018-01-11 Piotr Trojanek <trojanek@adacore.com>

3240 2018-01-11 Pascal Obry <obry@adacore.com>
3242 * libgnat/s-os_lib.adb (Normalize_Pathname): New implementation.
3244 2018-01-11 Bob Duff <duff@adacore.com>
3246 * doc/gnat_ugn/gnat_utility_programs.rst: Rewrite gnatpp documentation
3247 to match what the Libadalang-based version does.
3248 * doc/gnat_ugn/about_this_guide.rst: Update reference.
3250 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3252 * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
3253 if it contains at least one component declaration employing a function
3254 call returning on the secondary stack.
3256 2018-01-11 Yannick Moy <moy@adacore.com>
3258 * doc/gnat_rm/standard_and_implementation_defined_restrictions.rst:

3271 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3273 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
3274 has a delayed aspect which must be processed at the point the type is
3275 frozen. This mimics what is done when the predicate is provided by a

3291 Default_Sec_Stack_Size.
3292 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
3293 limit check so that the integer index does not overflow. Check the
3294 dynamic stack allocation does not cause the secondary stack pointer to
3296 (SS_Info): Align colons.
3297 (SS_Init): Cover the case when bootstraping with an old compiler that
3298 does not set Default_SS_Size.
3300 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3302 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
3303 legality of an inherited operation that may require overriding, ignore
3304 primitive_wrappers that correspond to explicit operations that override
3305 an interface primitive.
3306 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
3307 operation to which the class-wide expression applies is a protected op.
3308 with a primitive_wrapper, verify that the updated inherited expression
3309 does not contain an internal call to a protected function. This
3310 completes the implementation of AI12-0166.
3312 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3314 * ali.adb: Document the remaining letters available for ALI lines.
3315 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
3316 * ali.ads: Update type With_Record. Field
3317 Implicit_With_From_Instantiation is no longer in use. Add field
3319 * csinfo.adb (CSinfo): Remove the setup for attribute
3320 Implicit_With_From_Instantiation.
3321 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
3322 either implicitly or explicitly withed.
3323 (Is_Implicit_With_Clause): New routine.
3324 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
3325 confusion with the with clause attribute by the same name.
3326 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
3327 * rtsfind.adb (Maybe_Add_With): Code cleanup.
3328 * sem_ch8.adb (Present_System_Aux): Code cleanup.
3329 * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
3331 (Implicit_With_On_Parent): Mark the with clause as generated for a
3333 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
3334 instantiation are no longer marked as Implicit_With_From_Instantiation
3335 because they are already marked as implicit.
3336 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
3337 which marks implicit with clauses as related to an instantiation.
3338 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
3339 (Parent_With): New routine.
3340 (Set_Implicit_With_From_Instantiation): Removed.
3341 (Set_Parent_With): New routine.
3342 * sinfo.ads: Update the documentation of attribute Implicit_With.

3354 entity when the enclosing construct is a body.
3356 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
3358 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
3359 Secondary_Stack_Size handling as a pragma is now generated for the
3360 corresponding aspect instead of an attribute. Pragma expression is
3361 relocated instead of evaluated. Discriminant of the corresponding
3362 record type is referenced rather than the type discriminant.
3363 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
3364 Secondary_Stack_Size rep item checks to only look for the pragma rep.
3365 * sem_ch13.adb (Analyze_One_Aspect): Transform
3366 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
3367 because the attribute does not have visibility on a task type's

3370 Attribute_Secondary_Stack_Size.
3371 * snames.adb-tmpl, snames.ads-tmpl: Remove

3378 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3380 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
3381 individual action because the action may denote a complex expression,
3382 such as a case statement, which in turn may contain additional
3385 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3387 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
3388 analysis on a copy of the expression with a copy of the index variable,
3389 because full expansion will rewrite construct into a loop with the
3390 original loop variable.
3391 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
3392 expression is an iterated component association. Full analysis takes
3393 place when construct is rewritten as a loop.
3394 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
3395 is not safe for in-place assignment.
3396 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
3397 entity with no homonym and no other entity in the scope.
3399 2018-01-11 Justin Squirek <squirek@adacore.com>

3407 entity of the generated invariant procedure in order to construct a
3408 proper entity chain.

3417 * einfo.ads, einfo.adb (Activation_Record_Component,
3418 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
3419 Allow E_Discriminant.
3421 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
3423 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
3424 for atomic access once the component size is taken into account and
3425 also do it if the component type is Atomic or Volatile_Full_Access.
3427 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
