1026 2018-05-30 Bob Duff <duff@adacore.com>
1028 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
1029 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
1030 We need to analyze it as part of analyzing the block, so that if the
1031 call to Element that initializes Elmt_Decl returns on the secondary
1032 stack, the block will ss_mark/ss_release. This block is inside the
1033 loop; we don't want to leak memory until the loop exits. The purpose
1034 of analyzing Elmt_Decl first was to catch the error of modifying it,
1035 which is illegal because it's a loop parameter. The above causes us to
1036 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
1037 it on the Element entity, so we end up with an E_Variable node with the
1039 * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.
1040 * sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop

1059 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
1060 a package body that is a compilation unit may contain blocks that
1061 declare local subprograms. In Subprogram_Unnesting Mode such
1062 subprograms must be handled as nested inside the (implicit) elaboration
1063 procedure that executes that statement part. To handle properly uplevel
1064 references we construct that subprogram explicitly, to contain blocks
1065 and inner subprograms, The statement part of the compilation unit
1066 becomes a call to this subprogram. This is only done if blocks are

1402 * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
1403 value when converting a float value to a fixed-point value. This is

1459 constant with private view so we take the address of that entity.
1460 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
1461 any; all callers changed. Handle N_Indexed_Component like
1462 N_Attribute_Reference. Add N_Type_Conversion case.

1470 * exp_aggr.adb (Flatten): Copy tree of expression in a component
1471 association with a range or a set of discrete choices, rather than

1582 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
1583 of a fixed point type and the parent is a multiplying operation,
1584 resolve the operand with its own type because the context will impose a
1585 resulting type on the result of the multiplication by means of
1586 approriate conversion.
1588 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1590 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
1591 the in-place initialization aggregate created for pragmas
1592 Initialize_Scalars or Normalize_Scalars is performed with checks

1619 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1621 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
1622 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
1623 into three distring cases rather than in one loop which attempts to
1624 handle all three cases. This rewrite eliminates an issue where the last
1625 frame of the stack cannot be freed, thus causing the memory range of a
1626 new frame to approach the overflow point of the memory index type.
1627 Since the overflow is logically treated as a
1628 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
1629 (SS_Allocate_Static): New routine. The routine factorizes the static
1630 secondary stack-related code from the former SS_Allocate.

1640 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
1641 is created when the proper body of the stub is analyzed.
1642 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
1643 is the proper body of a subunit, the cloned body must be inserted in
1644 the declarative list that contains the stub.
1646 2018-05-25 Justin Squirek <squirek@adacore.com>
1648 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to

1683 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
1684 Validate_Derived_Type_Instance, to verify that all interfaces
1685 implemented by the formal type are also implemented by the actual. The
1686 verification is complicated when an interface of the formal is declared
1687 in a generic unit and the actual is declared in an instance of it.
1688 There is currently no mechanism to relate an interface declared within
1689 a generic to the corresponding interface in an instance, so we must
1690 traverse the list of interfaces of the actual, looking for a name
1691 match, and verifying that that interface is declared in an instance.
1693 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
1695 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra

2261 iteration of an Ada2012 loop is performed to determine the type of the

2927 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
2928 delegate the secondary stack management when there is no suitable
2929 transient context, and the transient scope was intended to manage the

3060 * exp_ch3.adb (Default_Initialize_Object): Call New_Copy_Tree on the
3061 result of Get_Simple_Init_Value and pass the source location of the
3062 object declaration's object_definition.
3064 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3066 * exp_ch6.adb (Make_Build_In_Place_Call_In_Object_Declaration): Handle
3067 properly object declarations with initializations that are
3068 build-in-place function calls, when there is an address specification,
3069 either as an aspect specification or an explicit attribute
3070 specification clause, for the initialized object.
3071 * freeze.adb (Check_Address_Clause): Do not remove side-effects from
3072 initial expressions in the case of a build-in-place call.
3074 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
3076 * sem_eval.adb (Is_Null_Range): Retrieve the full view when called on a
3077 private (sub)type; refactor to avoid early return statement.
3078 (Not_Null_Range): Same as above.
3080 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3082 * freeze.adb (Freeze_Entity): Ensure that a Ghost type is not
3083 concurrent, nor effectively volatile.
3084 * ghost.adb (Check_Ghost_Type): New routine.
3085 * ghost.ads (Check_Ghost_Type): New routine.
3086 * sem_util.adb (Is_Declaration): Reimplemented. The routine can now
3087 consider specific subsets of declarations.
3088 (Is_Declaration_Other_Than_Renaming): Removed. Its functionality is
3089 replicated by Is_Declaration.
3090 * sem_util.ads (Is_Declaration): New parameter profile. Update the
3092 (Is_Declaration_Other_Than_Renaming): Removed.
3094 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3096 * sem_ch5.adb (Analyze_Assignment): Assignments to variables that act
3097 as Part_Of consituents of single protected types are illegal when they
3098 take place inside a protected function.
3099 (Diagnose_Non_Variable_Lhs): Use Within_Function to check for an
3101 (Is_Protected_Part_Of_Constituent): New routine.
3102 (Within_Function): New routine.

3106 Bump copyright notices to 2018.
3108 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3110 * binde.adb, par-ch6.adb, par-ch9.adb, sem_ch12.adb, sem_ch13.adb:
3113 2018-01-11 Justin Squirek <squirek@adacore.com>
3115 * par-ch6.adb (Scan_Body_Or_Expression_Function): Add additional check
3116 to make sure a given expression function is properly parenthesized.
3118 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3120 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Check the
3121 categorization of a subprogram body which does not complete a previous
3124 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3126 * sem_ch10.adb (Check_Private_Child_Unit): Ensure that the enclosing
3127 scope of package Ada is Standard.
3129 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3131 * sem_ch13.adb (Replace_Type_Ref): Handle properly reference to a
3132 subcomponent of the current entity when building the body for a dynamic
3133 predicate function for a record with composite subcomponents.
3135 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>

3143 (Make_Build_In_Place_Call_In_Object_Declaration): Update the call to
3144 Establish_Transient_Scope.
3145 * exp_ch7.adb (Establish_Transient_Scope): Restructured. Delegate the
3146 management of the secondary stack to an enclosing scope if there is no
3147 suitable construct to wrap, and the transient scope was intended to
3148 manage the secondary stack.
3149 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
3150 is a valid boundary for a transient expression which comes from the
3151 statements of the alternative, otherwise alternatives cannot be
3152 wrapped. Assignments of controlled objects which have controlled
3153 actions suppressed now stop the traversal as there is no point in
3154 looking for an enclosing construct. Add several N_xxx_Body choices to
3155 the termination conditions for completeness.
3156 * exp_ch7.ads (Establish_Transient_Scope): Update the parameter profile
3157 and the associated comment on usage.
3158 * exp_smem.adb (Add_Shared_Var_Lock_Procs): Update the call to
3159 Establish_Transient_Scope.
3160 (Add_Write_After): Update the call to Establish_Transient_Scope.
3161 * sem_res.adb (Check_Initialization_Call): Removed.
3162 (Resolve_Actuals): Account for additional cases where finalization
3163 actions are required by utilizing predicate Needs_Finalization rather
3165 (Resolve_Call): Type initialization procedures can now utilize
3166 transient scopes to manage the secondary stack, thus preventing leaks
3167 during initialization. Remove the previous kludgy algorithm which
3168 attempts to manage the secondary stack at the object creation site.
3170 2018-01-11 Jerome Lambourg <lambourg@adacore.com>
3172 * libgnat/g-soliop__qnx.ads: New.

3209 * gnat_rm.texi: Regenerate.
3211 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3213 * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
3214 formsl type corresponding to the actual fixed point type is private,
3215 because in this case there can be no suspicious arithmetic operations
3216 in the generic unless they reference a formal subprogram. Clarify
3219 2018-01-11 Javier Miranda <miranda@adacore.com>
3221 * exp_util.adb (Remove_Side_Effects): No action done for functions
3222 returning class-wide types since it requires generating code using
3223 'reference and the CCG target has no secondary stack.
3224 * gnat1drv.adb: Disable building static dispatch tables when generating

3235 * libgnat/s-os_lib.adb (Normalize_Pathname): New implementation.
3237 2018-01-11 Bob Duff <duff@adacore.com>
3239 * doc/gnat_ugn/gnat_utility_programs.rst: Rewrite gnatpp documentation
3240 to match what the Libadalang-based version does.
3241 * doc/gnat_ugn/about_this_guide.rst: Update reference.
3243 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3245 * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
3246 if it contains at least one component declaration employing a function
3247 call returning on the secondary stack.
3249 2018-01-11 Yannick Moy <moy@adacore.com>

3264 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3266 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
3267 has a delayed aspect which must be processed at the point the type is
3268 frozen. This mimics what is done when the predicate is provided by a

3284 Default_Sec_Stack_Size.
3285 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
3286 limit check so that the integer index does not overflow. Check the
3287 dynamic stack allocation does not cause the secondary stack pointer to
3289 (SS_Info): Align colons.
3290 (SS_Init): Cover the case when bootstraping with an old compiler that
3291 does not set Default_SS_Size.
3293 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3295 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
3296 legality of an inherited operation that may require overriding, ignore
3297 primitive_wrappers that correspond to explicit operations that override
3298 an interface primitive.
3299 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
3300 operation to which the class-wide expression applies is a protected op.
3301 with a primitive_wrapper, verify that the updated inherited expression
3302 does not contain an internal call to a protected function. This
3303 completes the implementation of AI12-0166.
3305 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3307 * ali.adb: Document the remaining letters available for ALI lines.
3308 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
3309 * ali.ads: Update type With_Record. Field
3310 Implicit_With_From_Instantiation is no longer in use. Add field
3312 * csinfo.adb (CSinfo): Remove the setup for attribute
3313 Implicit_With_From_Instantiation.
3314 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
3315 either implicitly or explicitly withed.
3316 (Is_Implicit_With_Clause): New routine.
3317 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
3318 confusion with the with clause attribute by the same name.
3319 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
3320 * rtsfind.adb (Maybe_Add_With): Code cleanup.
3321 * sem_ch8.adb (Present_System_Aux): Code cleanup.
3322 * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
3324 (Implicit_With_On_Parent): Mark the with clause as generated for a
3326 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
3327 instantiation are no longer marked as Implicit_With_From_Instantiation
3328 because they are already marked as implicit.
3329 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
3330 which marks implicit with clauses as related to an instantiation.
3331 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
3332 (Parent_With): New routine.
3333 (Set_Implicit_With_From_Instantiation): Removed.
3334 (Set_Parent_With): New routine.
3335 * sinfo.ads: Update the documentation of attribute Implicit_With.

3347 entity when the enclosing construct is a body.
3349 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
3351 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
3352 Secondary_Stack_Size handling as a pragma is now generated for the
3353 corresponding aspect instead of an attribute. Pragma expression is
3354 relocated instead of evaluated. Discriminant of the corresponding
3355 record type is referenced rather than the type discriminant.
3356 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
3357 Secondary_Stack_Size rep item checks to only look for the pragma rep.
3358 * sem_ch13.adb (Analyze_One_Aspect): Transform
3359 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
3360 because the attribute does not have visibility on a task type's
3361 discriminants when the type's definition is expanded.
3362 (Analyze_Attribute_Definition_Clause): Remove handling of
3363 Attribute_Secondary_Stack_Size.
3364 * snames.adb-tmpl, snames.ads-tmpl: Remove
3365 Attribute_Secondary_Stack_Size, no longer used.

3373 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
3374 individual action because the action may denote a complex expression,
3375 such as a case statement, which in turn may contain additional
3378 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3380 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
3381 analysis on a copy of the expression with a copy of the index variable,
3382 because full expansion will rewrite construct into a loop with the
3383 original loop variable.
3384 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
3385 expression is an iterated component association. Full analysis takes
3386 place when construct is rewritten as a loop.
3387 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
3388 is not safe for in-place assignment.
3389 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
3390 entity with no homonym and no other entity in the scope.
3392 2018-01-11 Justin Squirek <squirek@adacore.com>

3400 entity of the generated invariant procedure in order to construct a
3401 proper entity chain.

3410 * einfo.ads, einfo.adb (Activation_Record_Component,
3411 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
3412 Allow E_Discriminant.
3414 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
3416 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
3417 for atomic access once the component size is taken into account and
3418 also do it if the component type is Atomic or Volatile_Full_Access.
3420 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
