508 * sem_ch6.adb (Analyze_Subprogram_Body_Helper, Mask_Type):
509 Refine the handling of freezing types for expression functions
510 that are not completions, when analyzing the generated body for
511 the function: the body is inserted at the end of the enclosing
512 declarative part, and its analysis may freeze types declared in
513 the same scope that have not been frozen yet.
515 2018-08-21 Ed Schonberg <schonberg@adacore.com>
517 * sem_ch6.adb: Remove Freeze_Expr_Types.

539 2018-08-21 Ed Schonberg <schonberg@adacore.com>
541 * sem_ch6.adb (Check_Synchronized_Overriding): The conformance
542 between an overriding protected operation and the overridden
543 abstract progenitor operation requires subtype conformance;
544 requiring equality of return types in the case of a function is
545 too restrictive and leads to spurious errors when the return
546 type is a generic actual.

1111 * exp_ch13.adb (Expand_N_Freeze_Entity): Handle subtype declared for an
1113 * freeze.adb (Freeze_Expression): Handle freeze of an entity defined
1114 outside of a subprogram body. This case was previously handled during
1115 preanalysis; the frozen entities were remembered and left pending until
1116 we continued freezeing entities outside of the subprogram. Now, when
1117 climbing the parents chain to locate the correct placement for the
1118 freezeing node, we check if the entity can be frozen and only when no
1119 enclosing node is marked as Must_Not_Freeze the entity is frozen.
1120 * sem_ch3.ads (Preanalyze_Default_Expression): Declaration moved to the
1122 * sem_ch3.adb (Preanalyze_Default_Expression): Code adjusted to invoke
1123 the new subprogram Preanalyze_With_Freezing_And_Resolve.

1125 (Analyze_Expression_Function, Process_Formals): Invoke
1126 Preanalyze_Formal_Expression instead of Preanalyze_Spec_Expression
1127 since the analysis of the formals may freeze entities.
1128 (Analyze_Subprogram_Body_Helper): Skip building the body of the
1129 class-wide clone for eliminated subprograms.
1130 * sem_res.ads, sem_res.adb (Preanalyze_And_Resolve): New subprogram.
1131 Its code is basically the previous version of this routine but extended
1132 with an additional parameter which is used to specify if during
1133 preanalysis we are allowed to freeze entities. If the new parameter is
1134 True then the subtree root node is marked as Must_Not_Freeze and no
1135 entities are frozen during preanalysis.
1136 (Preanalyze_And_Resolve): Invokes the internal version of
1137 Preanalyze_And_Resolve without entity freezing.
1138 (Preanalyze_With_Freezing_And_Resolve): Invokes the internal version of
1139 Prenalyze_And_Resolve with freezing enabled.

1173 enclosing scope already handles the secondary stack, take into account
1174 transient blocks nested in a block that do not manage the secondary
1175 stack and are located within a loop.

1179 * sem_util.adb (Enclosing_Subprogram): Protected entries and task
1180 entries must be treated separately: task entries are within the

1674 will not allocate the object on its side.

2126 (Start_Search): Modify to use Start_Search_Internal
2127 (Start_Search_Internal): Add to break out an extra flag for searching
2128 case insensative due to the potential for directories within the same
2129 OS to allow different casing schemes.
2130 * sysdep.c (__gnat_name_case_equivalence): Add as a default fallback

2202 2018-05-30 Bob Duff <duff@adacore.com>
2204 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
2205 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
2206 We need to analyze it as part of analyzing the block, so that if the
2207 call to Element that initializes Elmt_Decl returns on the secondary
2208 stack, the block will ss_mark/ss_release. This block is inside the
2209 loop; we don't want to leak memory until the loop exits. The purpose
2210 of analyzing Elmt_Decl first was to catch the error of modifying it,
2211 which is illegal because it's a loop parameter. The above causes us to
2212 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
2213 it on the Element entity, so we end up with an E_Variable node with the
2215 * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.
2216 * sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop
2217 parameter not allowed" error if Is_Loop_Parameter.
2218 * sem_util.adb (Is_Variable): Return False if Is_Loop_Parameter, to
2219 trigger the call to Diagnose_Non_Variable_Lhs.

2235 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
2236 a package body that is a compilation unit may contain blocks that
2237 declare local subprograms. In Subprogram_Unnesting Mode such
2238 subprograms must be handled as nested inside the (implicit) elaboration
2239 procedure that executes that statement part. To handle properly uplevel
2240 references we construct that subprogram explicitly, to contain blocks
2241 and inner subprograms, The statement part of the compilation unit
2242 becomes a call to this subprogram. This is only done if blocks are
2243 present in the statement list of the body.

2255 for subprogram instantiations to enter callable entity into Subp table.

2313 with a derivation of an untagged private type whose full view is a
2314 tagged type. In such case, collecting the list of primitives we may
2315 find two equality primitives: one associated with the untagged private

2604 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
2606 * exp_ch4.adb (Expand_Composite_Equality): For a composite (or FP)
2607 component type, do not expand array equality using the unconstrained
2608 base type, except for the case where the bounds of the type depend on a
2611 2018-05-28 Ed Schonberg <schonberg@adacore.com>
2613 * einfo.ads, einfo.adb (Needs_Activation_Record): New flag on
2614 access-to-subprogram types, to indicate that an indirect call through
2615 such a type requires an activation record when compiling for LLVM.
2616 * sem_ch3.adb (Access_Subprogram_Declaration): Set new flag as needed.
2618 2018-05-28 Ed Schonberg <schonberg@adacore.com>
2620 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
2621 when bounds of fixed type are static, to remove some spuerfluous
2622 implicit conversions and provide an accurate result when converting
2623 back and forth between the fixed point type and a floating point type.
2625 2018-05-28 Ed Schonberg <schonberg@adacore.com>
2627 * exp_unst.adb (Unnest_Subprogram): Prevent creation of empty
2630 2018-05-28 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
2632 * exp_unst.adb (Check_Static_Type): Add argument to indicate node to be
2633 replaced, if any; all callers changed.
2634 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
2635 constant with private view so we take the address of that entity.
2636 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
2637 any; all callers changed. Handle N_Indexed_Component like
2638 N_Attribute_Reference. Add N_Type_Conversion case.
2639 (Visit_Node): Indexed references can be uplevel if the type isn't
2641 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
2642 been relocated, set first_named pointer in original node as well.

2646 * exp_aggr.adb (Flatten): Copy tree of expression in a component
2647 association with a range or a set of discrete choices, rather than
2648 relocating the node. This avoids inconsistencies in the tree when
2649 handling nested subprograms with uplevel references for LLVM.

2663 unnecessary use of 'Unrestricted_Access.
2665 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
2667 * repinfo.adb (Expr_Value_S): New routine.
2668 (List_Linker_Section): Properly extract the value of the section
2671 2018-05-28 Patrick Bernardi <bernardi@adacore.com>
2673 * doc/gnat_ugn/building_executable_programs_with_gnat.rst: Update the
2674 description of the -D binder switch to reflect current usage.
2675 * gnat_ugn.texi: Regenerate.
2677 2018-05-28 Gary Dismukes <dismukes@adacore.com>

2702 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
2704 * sem_prag.adb (Process_Atomic_Independent_Shared_Volatile): Include
2705 the declarations of single concurrent types because they fall in the
2706 category of full type and object declarations.
2708 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>

2715 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
2716 includes a call to function to which it applies. This may mean an
2717 omission of an attribute reference 'Result, in particular if the
2718 function is pqrameterless.
2720 2018-05-28 Justin Squirek <squirek@adacore.com>

2727 * sem_res.adb (Resolve_Range): Re-resolve the low bound of a range in
2728 GNATprove mode, as the order of resolution (low then high) means that

2732 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
2734 * repinfo.adb (List_Array_Info): Start with an explicit blank line and
2735 end with the linker section, if any.
2736 (List_Entities): Do not output the linker section for record types,
2737 array types and variables.
2738 (Print_Expr): Factor out common processing for unary operators and
2739 special values. Adjust and reorder the various cases.
2740 (List_Object_Info): End with the linker section, if any.
2741 (List_Record_Info): Likewise.
2742 (List_Type_Info): Do not start with a blank line.
2744 2018-05-25 Nicolas Roche <roche@adacore.com>
2746 * libgnat/s-valrea.adb (Scan_Real): Abort computation once it is sure
2747 that the result will be either -infinite or +infinite.

2754 (Task_Storage_Size): Remove unused type.
2756 2018-05-25 Ed Schonberg <schonberg@adacore.com>
2758 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
2759 of a fixed point type and the parent is a multiplying operation,
2760 resolve the operand with its own type because the context will impose a
2761 resulting type on the result of the multiplication by means of
2762 approriate conversion.
2764 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
2766 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
2767 the in-place initialization aggregate created for pragmas
2768 Initialize_Scalars or Normalize_Scalars is performed with checks
2771 2018-05-25 Arnaud Charlet <charlet@adacore.com>
2773 * exp_aggr.adb (Convert_To_Positional): Bump default for
2774 Max_Others_Replicate to 32. Update comments.
2775 * osint.ads (Unknown_Attributes): No longer pretend this is a constant.

2787 2018-05-25 Ed Schonberg <schonberg@adacore.com>
2789 * exp_aggr.adb (Flatten): A quantified expression cannot be duplicated

2795 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
2797 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
2798 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
2799 into three distring cases rather than in one loop which attempts to
2800 handle all three cases. This rewrite eliminates an issue where the last
2801 frame of the stack cannot be freed, thus causing the memory range of a
2802 new frame to approach the overflow point of the memory index type.
2803 Since the overflow is logically treated as a
2804 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
2805 (SS_Allocate_Static): New routine. The routine factorizes the static
2806 secondary stack-related code from the former SS_Allocate.
2808 2018-05-25 Sergey Rybin <rybin@adacore.com>
2810 * doc/gnat_ugn/gnat_and_program_execution.rst: Add description of '-U'

2815 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
2816 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
2817 is created when the proper body of the stub is analyzed.
2818 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
2819 is the proper body of a subunit, the cloned body must be inserted in
2820 the declarative list that contains the stub.
2822 2018-05-25 Justin Squirek <squirek@adacore.com>
2824 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
2825 generate code for 6.5(8-10) so that we don't get an assertion error
2826 when dealing with an incomplete return type.
2828 2018-05-25 Arnaud Charlet <charlet@adacore.com>
2830 * pprint.adb (Expression_Name): Strip too long expressions to avoid
2831 carrying very large strings.

2857 2018-05-25 Ed Schonberg <schonberg@adacore.com>
2859 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
2860 Validate_Derived_Type_Instance, to verify that all interfaces
2861 implemented by the formal type are also implemented by the actual. The
2862 verification is complicated when an interface of the formal is declared
2863 in a generic unit and the actual is declared in an instance of it.
2864 There is currently no mechanism to relate an interface declared within
2865 a generic to the corresponding interface in an instance, so we must
2866 traverse the list of interfaces of the actual, looking for a name
2867 match, and verifying that that interface is declared in an instance.
2869 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
2871 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra
2872 assertions; replace function versions of Next_Formal/Next_Actual with

2914 <E_Record_Type>: Force the size of a storage unit on empty classes.
2915 * gcc-interface/utils.c (make_type_from_size) <BOOLEAN_TYPE>: Skip
2916 boolean types with precision 1 if the size is the expected one.

2938 in loops at the library level.
2940 2018-05-25 Ed Schonberg <schonberg@adacore.com>
2942 * sem_ch13.adb (Build_Predicate_Functions): The predicate function
2943 declaration is inserted into the tree and analyzed at that point, so
2944 should not be reinserted when the body is constructed. Inside a
2945 generic, ensure that the body is not inserted twice in the tree.

4078 (Uninstall_Discriminants_And_Pop_Scope): Same as above.
4079 * sem_util.adb (New_Copy_Tree): Same as above.
4080 * sem_ch7.adb (Generate_Parent_References): Prevent calls to
4081 Has_Discriminant on non-type entities that might happen when the
4082 compiled code has errors.
4083 * sem_ch3.adb (Derived_Type_Declaration): Only call
4084 Set_Has_Discriminant on type entities.

4098 attribute reference is legal within a generic unit when the prefix is a
4099 formal private type.
4101 2018-05-21 Hristian Kirtchev <kirtchev@adacore.com>
4103 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
4104 delegate the secondary stack management when there is no suitable
4105 transient context, and the transient scope was intended to manage the
4106 secondary stack because this causes premature reclamation. Change the
4107 transient scope creation logic by special casing assignment statements
4108 of controlled components for type initialization procedures.
4109 (Find_Node_To_Be_Wrapped): Renamed to Find_Transient_Context. Update
4110 the comment on usage.
4111 (Find_Transient_Context): Change the initinte loop into a while loop.
4112 Iterations schemes and iterator specifications are not valid transient
4113 contexts because they rely on special processing. Assignment statements
4114 are now treated as a normal transient context, special cases are
4115 handled by the caller. Add special processing for pragma Check.
4116 (Is_OK_Construct): Removed. Its functionality has been merged in
4117 routine Find_Transient_Context.
4118 * sem_ch5.adb (Check_Call): Reimplemented. Add code to properly
4119 retrieve the subprogram being invoked. Use a more accurate predicate
4120 (Requires_Transient_Scope) to determine that the function will emply
4121 the secondary stack.

4322 management of the secondary stack to an enclosing scope if there is no
4323 suitable construct to wrap, and the transient scope was intended to
4324 manage the secondary stack.
4325 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
4326 is a valid boundary for a transient expression which comes from the
4327 statements of the alternative, otherwise alternatives cannot be
4328 wrapped. Assignments of controlled objects which have controlled
4329 actions suppressed now stop the traversal as there is no point in
4330 looking for an enclosing construct. Add several N_xxx_Body choices to
4331 the termination conditions for completeness.

4333 and the associated comment on usage.

4338 (Resolve_Actuals): Account for additional cases where finalization
4339 actions are required by utilizing predicate Needs_Finalization rather
4341 (Resolve_Call): Type initialization procedures can now utilize
4342 transient scopes to manage the secondary stack, thus preventing leaks
4343 during initialization. Remove the previous kludgy algorithm which
4344 attempts to manage the secondary stack at the object creation site.

4473 primitive_wrappers that correspond to explicit operations that override
4474 an interface primitive.
4475 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
4476 operation to which the class-wide expression applies is a protected op.
4477 with a primitive_wrapper, verify that the updated inherited expression
4478 does not contain an internal call to a protected function. This
4479 completes the implementation of AI12-0166.

4492 (Is_Implicit_With_Clause): New routine.
4493 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
4494 confusion with the with clause attribute by the same name.

4506 which marks implicit with clauses as related to an instantiation.

4525 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
4527 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
4528 Secondary_Stack_Size handling as a pragma is now generated for the
4529 corresponding aspect instead of an attribute. Pragma expression is
4530 relocated instead of evaluated. Discriminant of the corresponding
4531 record type is referenced rather than the type discriminant.
4532 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
4533 Secondary_Stack_Size rep item checks to only look for the pragma rep.
4534 * sem_ch13.adb (Analyze_One_Aspect): Transform
4535 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
4536 because the attribute does not have visibility on a task type's

4539 Attribute_Secondary_Stack_Size.

4556 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
4557 analysis on a copy of the expression with a copy of the index variable,
4558 because full expansion will rewrite construct into a loop with the
4559 original loop variable.
4560 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
4561 expression is an iterated component association. Full analysis takes
4562 place when construct is rewritten as a loop.
4563 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
4564 is not safe for in-place assignment.
