Note that the "??? not (always) true..." comment was not true; the Subunit_Parent never points to the spec. (N_Compilation_Unit): Improve documentation.

The last point is somewhat subtle. This is how we prevent covert fat-to-nonfat type conversions via things like "Not_Extended_Type'(Extended_Ptr.all'Access)" or passing Extended_Ptr.all as an actual parameter corresponding to an explicitly aliased formal parameter. * sem_util.ads (Is_Extended_Access_Type): Declare new function.

Replace code for determining whether we have an indexed aggregate with call to new function Sem_Aggr.Is_Indexed_Aggregate. Remove test of whether Empty_Subp is a function, since it must be a function. Move Default and Count_Type to be locals of a new block enclosing the code that creates the object to hold the aggregate length, and set them according to the default and type of the Empty function's parameter when present (and to Empty and Standard_Natural otherwise). Use Siz_Exp for the aggregate length when set, and use Empty's default length when available, and use zero for the length otherwise. In generating the call to the New_Indexed function, use the determined lower and upper bounds if determined earlier by Aggregate_Size, and otherwise compute those from the index type's lower bound and the determined aggregate length. In the case where a call to Empty is generated and the function has a formal parameter, pass the value saved in Siz_Decl (otherwise the parameter list is empty). Remove code specific to making a parameterless call to the Empty function. Extend the code for handling positional container aggregates to account for types that define Assign_Indexed, rather than just Add_Unnamed, and in the case of indexed aggregates, create a temporary object to hold values of the aggregate's key index, and initialize and increment that temporary for each call generated to the Assign_Indexed procedure. For named container aggregates that have key choices given by ranges, call Expand_Range_Component to generate a loop that will call the appropriate insertion procedure for each value of the range. For indexed aggregates with a Component_Associations list, set and use the Assign_Indexed procedure for each component association, whether or not there's an iterator specification. (Add_Range_Size): Add code to determine the low and high bounds of the range and capture those in up-level variables when their value is less than or greater than (respectively) the current minimum and maximum bounds values. (Aggregate_Size): Separately handle the case where a single choice is of a discrete type, and call Add_Range_Size to take its value into consideration for determination of min and max bounds of the aggregate. Add comments in a couple of places. (Build_Siz_Exp): Remove the last sentence and "???" from the comment that talks about accumulating nonstatic sizes, since that sentence seems to be obsolete. Record the low and high bound values in Choice_Lo and Choice_Hi in the case of a nonstatic range. (Expand_Iterated_Component): Set the Defining_Identifier of the iterator specification to the Loop_Id in the N_Iterated_Component_Association case. (Expand_Range_Component): Procedure unnested from the block handling indexed aggregates in Expand_Container_Aggregate, and moved to top level of that procedure so it can also be called for Add_Named cases. A formal parameter Insert_Op is added, and existing calls to this procedure are changed to pass the appropriate insertion procedure's Entity. * sem_aggr.ads: Add with_clause for Sinfo.Nodes. (Is_Indexed_Aggregate): New function for use by Resolve_Container_Aggregate and Expand_Container_Aggregate. * sem_aggr.adb: Add with_clause for Sem_Ch5. Move with_clause for Sinfo.Nodes to sem_aggr.ads. (Is_Indexed_Aggregate): New function to determine whether a container aggregate is a container aggregate (replacing local variable of the same name in Resolve_Container_Aggregate). (Resolve_Iterated_Association): Remove part of comment saying that a Key_Expression is always present. Set Parent field of the copy of a component association with a loop parameter specification. On the setting of Loop_Param_Id, account for a Loop_Parameter_Specification being changed into an Iterator_Specification as a result of being analyzed. Only call Preanalyze_And_Resolve on Key_Expr when a key expression is actually present. Remove loop for handling choices for the case of an N_Component_Association with a Defining_Identifier (there shouldn't be more than one choice in this case, and add an assertion to ensure that). Also add code here to handle the case where the choice is a function call, creating an iterator_specification analyzing it, and call Resolve_Iterated_Association recursively to process it. Add error check to enforce RM22 4.3.5(27), which requires that the type of the loop parameter must be the same as the key type when there is no key expression and the aggregate is an indexed aggregate or has an Add_Named op. (Resolve_Container_Aggregate): In the Add_Unnamed case, call Resolve_Iterated_Association for both N_Iterated_Element_Association and N_Component_Association (rather than just the latter). Remove error check for nonstatic choices in component associations in Add_Named cases (multiple named nonstatic associations are fine except in indexed aggregates). Remove local variable Is_Indexed_Aggregate, replaced with new library-level function of the same name, and add test of Is_Indexed_Aggregate in the case where the aggregate type has an Assign_Indexed operation, as a guard for doing error checks for indexed aggregates. For indexed aggregate resolution, do not call Analyze_And_Resolve on the expression of an N_Component_Association in the "box association" case. Move error checks for indexed aggregates with iterated associations that flag cases where an association is a loop_parameter_specification with an iterator filter or a key expression (violation of RM22 4.3.5(28/5)), from the loop that checks for contiguous and nonoverlapping choices and into the preceding association loop after the call to Resolve_Iterated_Association.

Delete useless pattern matching. 2024-05-14 Ronan Desplanques * usage.adb (Usage): Fix enabled-by-default indicators. 2024-05-14 Philippe Gil * libgnat/s-win32.ads (LocalFileTimeToFileTime): Swap parameters. 2024-05-14 Ronan Desplanques * restrict.adb (Violation_Of_No_Dependence): Tweak error reporting calls. 2024-05-14 Ronan Desplanques * sem_prag.adb (Analyze_Pragma): Adapt call to new signature. * erroutc.ads (Set_Specific_Warning_Off): change signature and update documentation. (Validate_Specific_Warnings): Move ... * errout.adb: ... here and change signature. Also move body of Validate_Specific_Warnings from erroutc.adb. (Finalize): Adapt call. * errout.ads (Set_Specific_Warning_Off): Adapt signature of renaming. * erroutc.adb (Set_Specific_Warning_Off): Adapt signature and body. (Validate_Specific_Warnings): Move to the body of Errout. (Warning_Specifically_Suppressed): Adapt body. 2024-05-14 Eric Botcazou * exp_aggr.adb (Build_Array_Aggr_Code): Pass N in the call to Build_Initialization_Call. (Build_Record_Aggr_Code): Likewise. (Convert_Aggr_In_Object_Decl): Likewise. (Initialize_Discriminants): Likewise. * exp_ch3.ads (Build_Initialization_Call): Replace Loc witn N. * exp_ch3.adb (Build_Array_Init_Proc): Pass N in the call to Build_Initialization_Call. (Build_Default_Initialization): Likewise. (Expand_N_Object_Declaration): Likewise. (Build_Initialization_Call): Replace Loc witn N parameter and add Loc local variable. Build a default subtype for an allocator of a discriminated type with defaulted discriminants. (Build_Record_Init_Proc): Pass the declaration of components in the call to Build_Initialization_Call. * exp_ch6.adb (Make_CPP_Constructor_Call_In_Allocator): Pass the allocator in the call to Build_Initialization_Call. 2024-05-14 Ronan Desplanques * sem_warn.adb (Warn_On_Overlapping_Actuals): Fix typo. 2024-05-14 Gary Dismukes * exp_util.adb (Find_Hook_Context): Exclude N_*Aggregate Nkinds of Parent (Par) from the early return in the second loop of the In_Cond_Expr case, to prevent returning an aggregate from this function rather than the enclosing declaration or statement. 2024-05-14 Steve Baird * exp_attr.adb: Replace 6 "not Present" tests with equivalent calls to "No". 2024-05-14 Eric Botcazou * exp_ch3.adb (Expand_N_Object_Declaration): Examine the Expression field after the call to Default_Initialize_Object in order to set Is_Known_Null, as well as Is_Known_Non_Null, on an access object. 2024-05-14 Steve Baird * exp_attr.adb: Change name of package Cached_Streaming_Ops to reflect the fact that it is now also used for Put_Image procedures. Similarly change other "Streaming_Op" names therein. Add Validate_Cached_Candidate procedure to detect case where a subprogram found in the cache cannot be reused. Add new generic procedure Build_And_Insert_Type_Attr_Subp; the "Build" part is handled by just calling a formal procedure; the bulk of this (generic) procedure's code has to with deciding where in the tree to insert the newly-constructed subprogram. Replace each later "Build" call (and the following Insert_Action or Compile_Stream_Body_In_Scope call) with a declare block that instantiates and then calls this generic procedure. Delete the now-unused procedure Compile_Stream_Body_In_Scope. A constructed subprogram is entered in the appropriate cache if the corresponding type is untagged; this replaces more complex tests. A new function Interunit_Ref_OK is added to determine whether an attribute reference occuring in one unit can safely refer to a cached subprogram declared in another unit. * exp_ch3.adb (Build_Predefined_Primitive_Bodies): A formal parameter was deleted, so delete the corresponding actual in a call. * exp_put_image.adb (Build_Array_Put_Image_Procedure): Because the procedure being built may be referenced more than once, the generated procedure takes its source position info from the type declaration instead of the (first) attribute reference. (Build_Record_Put_Image_Procedure): Likewise. * exp_put_image.ads (Build_Array_Put_Image_Procedure): Eliminate now-unused Nod parameter. (Build_Record_Put_Image_Procedure): Eliminate now-unused Loc parameter. * sem_ch3.adb (Constrain_Discriminated_Type): For declaring a subtype with a discriminant constraint, ignore privacy if Comes_From_Source is false (as is already done if Is_Instance is true). * sem_res.adb (Resolve): When passed two type entities that have the same underlying base type, Sem_Type.Covers may return False in some cases because of privacy. [This can happen even if Is_Private_Type returns False both for Etype (N) and for Typ; Covers calls Base_Type, which can take a non-private argument and yield a private result.] If Comes_From_Source (N) is False (e.g., for a compiler-generated Put_Image or streaming subprogram), then avoid that scenario by not calling Covers. Covers already has tests for doing this sort of thing (see the calls therein to Full_View_Covers), but the Comes_From_Source test is too coarse to apply there. So instead we handle the problem here at the call site. (Original_Implementation_Base_Type): A new function. Same as Implementation_Base_Type except if the Original_Node attribute of a non-derived type declaration indicates that it once was a derived type declaration. Needed for looking through privacy. (Valid Conversion): Ignore privacy when converting between different views of the same type if Comes_From_Source is False for the conversion. (Valid_Tagged_Conversion): An ancestor-to-descendant conversion is not an illegal downward conversion if there is no type extension involved (because the derivation was from an untagged view of the parent type). 2024-05-14 Steve Baird * sem_ch5.adb (Analyze_Case_Statement): Emit a message and return early in the case where general case statements are allowed but the selector expression is of a private type. This is done to avoid a bugbox. 2024-05-14 Justin Squirek * sem_util.adb (Set_Referenced_Modified): Use Original_Node to avoid recursive calls on expanded / internal objects such that source nodes get appropriately marked as referenced. 2024-05-14 Ronan Desplanques * sem_warn.adb (Warn_On_Overlapping_Actuals): Stop ignoring warning suppression settings. 2024-05-14 Eric Botcazou * exp_util.adb (Build_Allocate_Deallocate_Proc): Pass the alignment parameter in the inner call for a secondary stack allocation too. 2024-05-14 Javier Miranda * sem_ch10.adb (Install_Inherited_Policy_Pragmas): New subprogram.
