621 comment about the memset case.
623 2018-05-30 Bob Duff <duff@adacore.com>
625 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
626 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
627 We need to analyze it as part of analyzing the block, so that if the
628 call to Element that initializes Elmt_Decl returns on the secondary
629 stack, the block will ss_mark/ss_release. This block is inside the
630 loop; we don't want to leak memory until the loop exits. The purpose
631 of analyzing Elmt_Decl first was to catch the error of modifying it,
632 which is illegal because it's a loop parameter. The above causes us to
633 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
634 it on the Element entity, so we end up with an E_Variable node with the
636 * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.

656 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
657 a package body that is a compilation unit may contain blocks that
658 declare local subprograms. In Subprogram_Unnesting Mode such
659 subprograms must be handled as nested inside the (implicit) elaboration
660 procedure that executes that statement part. To handle properly uplevel
661 references we construct that subprogram explicitly, to contain blocks
662 and inner subprograms, The statement part of the compilation unit
663 becomes a call to this subprogram. This is only done if blocks are
664 present in the statement list of the body.

1041 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
1042 when bounds of fixed type are static, to remove some spuerfluous
1043 implicit conversions and provide an accurate result when converting
1044 back and forth between the fixed point type and a floating point type.
1046 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1048 * exp_unst.adb (Unnest_Subprogram): Prevent creation of empty
1051 2018-05-28 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
1053 * exp_unst.adb (Check_Static_Type): Add argument to indicate node to be
1054 replaced, if any; all callers changed.
1055 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
1056 constant with private view so we take the address of that entity.
1057 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
1058 any; all callers changed. Handle N_Indexed_Component like
1059 N_Attribute_Reference. Add N_Type_Conversion case.
1060 (Visit_Node): Indexed references can be uplevel if the type isn't
1062 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
1063 been relocated, set first_named pointer in original node as well.

1067 * exp_aggr.adb (Flatten): Copy tree of expression in a component
1068 association with a range or a set of discrete choices, rather than

1084 unnecessary use of 'Unrestricted_Access.
1086 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
1088 * repinfo.adb (Expr_Value_S): New routine.
1089 (List_Linker_Section): Properly extract the value of the section
1092 2018-05-28 Patrick Bernardi <bernardi@adacore.com>
1094 * doc/gnat_ugn/building_executable_programs_with_gnat.rst: Update the
1095 description of the -D binder switch to reflect current usage.
1096 * gnat_ugn.texi: Regenerate.
1098 2018-05-28 Gary Dismukes <dismukes@adacore.com>

1123 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
1125 * sem_prag.adb (Process_Atomic_Independent_Shared_Volatile): Include
1126 the declarations of single concurrent types because they fall in the
1127 category of full type and object declarations.
1129 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>

1136 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
1137 includes a call to function to which it applies. This may mean an
1138 omission of an attribute reference 'Result, in particular if the
1139 function is pqrameterless.
1141 2018-05-28 Justin Squirek <squirek@adacore.com>

1148 * sem_res.adb (Resolve_Range): Re-resolve the low bound of a range in
1149 GNATprove mode, as the order of resolution (low then high) means that

1153 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
1155 * repinfo.adb (List_Array_Info): Start with an explicit blank line and
1156 end with the linker section, if any.
1157 (List_Entities): Do not output the linker section for record types,
1158 array types and variables.
1159 (Print_Expr): Factor out common processing for unary operators and
1160 special values. Adjust and reorder the various cases.
1161 (List_Object_Info): End with the linker section, if any.
1162 (List_Record_Info): Likewise.
1163 (List_Type_Info): Do not start with a blank line.
1165 2018-05-25 Nicolas Roche <roche@adacore.com>
1167 * libgnat/s-valrea.adb (Scan_Real): Abort computation once it is sure
1168 that the result will be either -infinite or +infinite.

1175 (Task_Storage_Size): Remove unused type.
1177 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1179 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
1180 of a fixed point type and the parent is a multiplying operation,
1181 resolve the operand with its own type because the context will impose a
1182 resulting type on the result of the multiplication by means of
1183 approriate conversion.
1185 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1187 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
1188 the in-place initialization aggregate created for pragmas
1189 Initialize_Scalars or Normalize_Scalars is performed with checks
1192 2018-05-25 Arnaud Charlet <charlet@adacore.com>
1194 * exp_aggr.adb (Convert_To_Positional): Bump default for
1195 Max_Others_Replicate to 32. Update comments.
1196 * osint.ads (Unknown_Attributes): No longer pretend this is a constant.

1208 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1210 * exp_aggr.adb (Flatten): A quantified expression cannot be duplicated

1216 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1218 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
1219 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
1220 into three distring cases rather than in one loop which attempts to
1221 handle all three cases. This rewrite eliminates an issue where the last
1222 frame of the stack cannot be freed, thus causing the memory range of a
1223 new frame to approach the overflow point of the memory index type.
1224 Since the overflow is logically treated as a
1225 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
1226 (SS_Allocate_Static): New routine. The routine factorizes the static
1227 secondary stack-related code from the former SS_Allocate.
1229 2018-05-25 Sergey Rybin <rybin@adacore.com>
1231 * doc/gnat_ugn/gnat_and_program_execution.rst: Add description of '-U'

1236 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
1237 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
1238 is created when the proper body of the stub is analyzed.
1239 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
1240 is the proper body of a subunit, the cloned body must be inserted in
1241 the declarative list that contains the stub.
1243 2018-05-25 Justin Squirek <squirek@adacore.com>
1245 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
1246 generate code for 6.5(8-10) so that we don't get an assertion error
1247 when dealing with an incomplete return type.
1249 2018-05-25 Arnaud Charlet <charlet@adacore.com>
1251 * pprint.adb (Expression_Name): Strip too long expressions to avoid

1278 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1280 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
1281 Validate_Derived_Type_Instance, to verify that all interfaces
1282 implemented by the formal type are also implemented by the actual. The
1283 verification is complicated when an interface of the formal is declared
1284 in a generic unit and the actual is declared in an instance of it.
1285 There is currently no mechanism to relate an interface declared within
1286 a generic to the corresponding interface in an instance, so we must
1287 traverse the list of interfaces of the actual, looking for a name
1288 match, and verifying that that interface is declared in an instance.
1290 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
1292 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra
1293 assertions; replace function versions of Next_Formal/Next_Actual with

1335 <E_Record_Type>: Force the size of a storage unit on empty classes.
1336 * gcc-interface/utils.c (make_type_from_size) <BOOLEAN_TYPE>: Skip

1359 in loops at the library level.
1361 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1363 * sem_ch13.adb (Build_Predicate_Functions): The predicate function
1364 declaration is inserted into the tree and analyzed at that point, so
1365 should not be reinserted when the body is constructed. Inside a
1366 generic, ensure that the body is not inserted twice in the tree.

2516 2018-05-21 Ed Schonberg <schonberg@adacore.com>
2518 * sem_attr.adb (Analyze_Attribute, case Scalar_Storage_Order): The
2519 attribute reference is legal within a generic unit when the prefix is a
2520 formal private type.
2522 2018-05-21 Hristian Kirtchev <kirtchev@adacore.com>
2524 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
2525 delegate the secondary stack management when there is no suitable
2526 transient context, and the transient scope was intended to manage the
2527 secondary stack because this causes premature reclamation. Change the
2528 transient scope creation logic by special casing assignment statements
2529 of controlled components for type initialization procedures.
2530 (Find_Node_To_Be_Wrapped): Renamed to Find_Transient_Context. Update
2531 the comment on usage.
2532 (Find_Transient_Context): Change the initinte loop into a while loop.
2533 Iterations schemes and iterator specifications are not valid transient
2534 contexts because they rely on special processing. Assignment statements
2535 are now treated as a normal transient context, special cases are
2536 handled by the caller. Add special processing for pragma Check.
2537 (Is_OK_Construct): Removed. Its functionality has been merged in
2538 routine Find_Transient_Context.
2539 * sem_ch5.adb (Check_Call): Reimplemented. Add code to properly
2540 retrieve the subprogram being invoked. Use a more accurate predicate
2541 (Requires_Transient_Scope) to determine that the function will emply
2542 the secondary stack.

2659 object declaration's object_definition.
2661 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2663 * exp_ch6.adb (Make_Build_In_Place_Call_In_Object_Declaration): Handle
2664 properly object declarations with initializations that are
2665 build-in-place function calls, when there is an address specification,
2666 either as an aspect specification or an explicit attribute
2667 specification clause, for the initialized object.
2668 * freeze.adb (Check_Address_Clause): Do not remove side-effects from

2686 replicated by Is_Declaration.
2687 * sem_util.ads (Is_Declaration): New parameter profile. Update the

2693 * sem_ch5.adb (Analyze_Assignment): Assignments to variables that act
2694 as Part_Of consituents of single protected types are illegal when they
2695 take place inside a protected function.

2710 2018-01-11 Justin Squirek <squirek@adacore.com>
2712 * par-ch6.adb (Scan_Body_Or_Expression_Function): Add additional check
2713 to make sure a given expression function is properly parenthesized.
2715 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>

2724 scope of package Ada is Standard.
2726 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2728 * sem_ch13.adb (Replace_Type_Ref): Handle properly reference to a
2729 subcomponent of the current entity when building the body for a dynamic
2730 predicate function for a record with composite subcomponents.

2742 * exp_ch7.adb (Establish_Transient_Scope): Restructured. Delegate the
2743 management of the secondary stack to an enclosing scope if there is no
2744 suitable construct to wrap, and the transient scope was intended to
2745 manage the secondary stack.
2746 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
2747 is a valid boundary for a transient expression which comes from the
2748 statements of the alternative, otherwise alternatives cannot be
2749 wrapped. Assignments of controlled objects which have controlled
2750 actions suppressed now stop the traversal as there is no point in
2751 looking for an enclosing construct. Add several N_xxx_Body choices to
2752 the termination conditions for completeness.
2753 * exp_ch7.ads (Establish_Transient_Scope): Update the parameter profile
2754 and the associated comment on usage.
2755 * exp_smem.adb (Add_Shared_Var_Lock_Procs): Update the call to
2756 Establish_Transient_Scope.
2757 (Add_Write_After): Update the call to Establish_Transient_Scope.
2758 * sem_res.adb (Check_Initialization_Call): Removed.
2759 (Resolve_Actuals): Account for additional cases where finalization
2760 actions are required by utilizing predicate Needs_Finalization rather
2762 (Resolve_Call): Type initialization procedures can now utilize
2763 transient scopes to manage the secondary stack, thus preventing leaks
2764 during initialization. Remove the previous kludgy algorithm which
2765 attempts to manage the secondary stack at the object creation site.
2767 2018-01-11 Jerome Lambourg <lambourg@adacore.com>

2810 * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the

2812 because in this case there can be no suspicious arithmetic operations
2813 in the generic unless they reference a formal subprogram. Clarify
2816 2018-01-11 Javier Miranda <miranda@adacore.com>
2818 * exp_util.adb (Remove_Side_Effects): No action done for functions
2819 returning class-wide types since it requires generating code using
2820 'reference and the CCG target has no secondary stack.

2881 Default_Sec_Stack_Size.
2882 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
2883 limit check so that the integer index does not overflow. Check the
2884 dynamic stack allocation does not cause the secondary stack pointer to

2887 (SS_Init): Cover the case when bootstraping with an old compiler that
2888 does not set Default_SS_Size.
2890 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2892 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
2893 legality of an inherited operation that may require overriding, ignore
2894 primitive_wrappers that correspond to explicit operations that override
2895 an interface primitive.
2896 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
2897 operation to which the class-wide expression applies is a protected op.
2898 with a primitive_wrapper, verify that the updated inherited expression
2899 does not contain an internal call to a protected function. This
2900 completes the implementation of AI12-0166.
2902 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2904 * ali.adb: Document the remaining letters available for ALI lines.
2905 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
2906 * ali.ads: Update type With_Record. Field
2907 Implicit_With_From_Instantiation is no longer in use. Add field
2909 * csinfo.adb (CSinfo): Remove the setup for attribute
2910 Implicit_With_From_Instantiation.
2911 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
2912 either implicitly or explicitly withed.
2913 (Is_Implicit_With_Clause): New routine.
2914 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
2915 confusion with the with clause attribute by the same name.
2916 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
2917 * rtsfind.adb (Maybe_Add_With): Code cleanup.

2924 instantiation are no longer marked as Implicit_With_From_Instantiation
2925 because they are already marked as implicit.
2926 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
2927 which marks implicit with clauses as related to an instantiation.
2928 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
2929 (Parent_With): New routine.
2930 (Set_Implicit_With_From_Instantiation): Removed.
2931 (Set_Parent_With): New routine.

2944 entity when the enclosing construct is a body.
2946 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
2948 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
2949 Secondary_Stack_Size handling as a pragma is now generated for the
2950 corresponding aspect instead of an attribute. Pragma expression is
2951 relocated instead of evaluated. Discriminant of the corresponding
2952 record type is referenced rather than the type discriminant.
2953 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
2954 Secondary_Stack_Size rep item checks to only look for the pragma rep.
2955 * sem_ch13.adb (Analyze_One_Aspect): Transform
2956 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
2957 because the attribute does not have visibility on a task type's
2958 discriminants when the type's definition is expanded.
2959 (Analyze_Attribute_Definition_Clause): Remove handling of
2960 Attribute_Secondary_Stack_Size.
2961 * snames.adb-tmpl, snames.ads-tmpl: Remove

2977 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
2978 analysis on a copy of the expression with a copy of the index variable,
2979 because full expansion will rewrite construct into a loop with the
2980 original loop variable.
2981 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
2982 expression is an iterated component association. Full analysis takes
2983 place when construct is rewritten as a loop.
2984 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
2985 is not safe for in-place assignment.
2986 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
2987 entity with no homonym and no other entity in the scope.

3014 for atomic access once the component size is taken into account and
3015 also do it if the component type is Atomic or Volatile_Full_Access.
3017 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
