(Expand_N_In): Remove wrong handling of null access types and corresponding comment. * exp_intr.adb (Expand_Dispatching_Constructor_Call): Generate a call to CW_Membership instead of using Build_CW_Membership. * rtsfind.ads: Add CW_Membership. * exp_atag.ads, exp_atag.adb (Build_CW_Membership): Removed. * einfo.ads: Fix typo. * libgnat/a-tags.ads, libgnat/a-tags.adb (CW_Membership): Moved back to spec. 2020-07-07 Ed Schonberg * exp_ch3.adb (Build_Access_Subprogram_Wrapper_Body): Create proper subprogram specification for body, using names in the subprogram declaration but distinct entities. * exp_ch6.adb (Expand_Call): If this is an indirect call involving a subprogram wrapper, insert pointer parameter in list of actuals with a parameter association, not as a positional parameter. 2020-07-07 Justin Squirek * exp_ch6.adb (Expand_Branch): Verify the original node is a conditional expression before recursing further. (Insert_Level_Assign): Transform assertion into an explicit raise. 2020-07-07 Steve Baird * sem_attr.adb (Eval_Attribute): Generalize static evaluation of Size attribute references to also handle Max_Size_In_Storage_Elements references. 2020-07-07 Javier Miranda * sem_util.adb (Is_Potentially_Unevaluated): Code cleanup. 2020-07-07 Eric Botcazou * checks.ads (Expander Routines): Update the description of the Do_Range_Check mechanism. * checks.adb (Selected_Range_Checks): Fix typo. * exp_ch9.adb: Add with and use clause for Checks. (Actual_Index_Expression): Generate a range check if requested. (Entry_Index_Expression): Likewise. * sem_attr.adb (Resolve_Attribute) : Call Apply_Scalar_Range_Check instead of Apply_Range_Check. * sem_ch9.adb (Analyze_Accept_Statement): Likewise. * sem_res.adb (Resolve_Entry): Likewise, after having set the actual index type on the prefix of the indexed component. (Resolve_Indexed_Component): Remove useless conditional construct. 2020-07-07 Piotr Trojanek * contracts.adb (Analyze_Entry_Or_Subprogram_Contract, Process_Preconditions_For): Freeze expression that has been relocated to pragma Precondition, not the expression which is still in the aspect. 2020-07-07 Arnaud Charlet * sem_ch6.adb (Check_Conformance): Remove unnecessary (and wrong) code. * sem_ch8.adb (Check_Null_Exclusion): Post error at proper location. Introduce new helper Null_Exclusion_Mismatch and fix implementation wrt formal subprograms used in generic bodies. (Analyze_Subprogram_Renaming): Fix missing setting of Error_Msg_Sloc. (Analyze_Object_Renaming): Replace "in Anonymous_Access_Kind" by Is_Anonymous_Access_Type. * sem_util.adb (Has_Null_Exclusion): Fix handling of N_Parameter_Specification. * sem_ch12.adb (Instantiate_Object): Replace "in Anonymous_Access_Kind" by Is_Anonymous_Access_Type. 2020-07-07 Ed Schonberg * freeze.adb (Freeze_Expr_Types): Freeze the designated type of the explicit dereference. 2020-07-07 Javier Miranda * sem_util.adb (Is_Potentially_Unevaluated): Protect reading attribute Etype. 2020-07-07 Bob Duff * libgnat/g-catiio.adb (Value, Parse_ISO_8601): Unsuppress checks, and don't rely on 'Valid. 2020-07-07 Arnaud Charlet * Makefile.rtl: Remove dead code. * doc/gnat_ugn/building_executable_programs_with_gnat.rst: Document gnatbind -xdr switch. * gnat_ugn.texi: Regenerate. 2020-07-07 Piotr Trojanek * doc/gnat_ugn/building_executable_programs_with_gnat.rst (Validity Checking): Add "p" to the list of switches enabled by -gnatVa. * gnat_ugn.texi: Regenerate. 2020-07-07 Ghjuvan Lacambre * sem_ch13.adb (Analyze_Attribute_Definition_Clause): Add call to Check_Restriction_No_Specification_Of_Aspect. * sem_prag.adb (Analyze_Pragma): Likewise. * restrict.ads (Check_Restriction_No_Specification_Of_Aspect): Mention possible new node kinds in documentation. * restrict.adb (Check_Restriction_No_Specification_Of_Aspect): Retrieve aspect id from different fields if given node is an N_Pragma or an N_Attribute_Definition_Clause. 2020-07-07 Gary Dismukes * contracts.adb (Add_Invariant_And_Predicate_Checks): Relax the condition for doing invariant checks so that in-mode parameters of procedures are also checked (required by AI05-0289, and restricted to procedures by AI12-0044). This is done in a procedure's nested postconditions procedure. * exp_ch6.adb (Expand_Actuals): Also perform postcall invariant checks for in parameters of procedures (but not functions). Moved invariant-checking code to end of Expand_Actuals (including the nested function Is_Public_Subp). 2020-07-07 Piotr Trojanek * sem_aggr.adb (Resolve_Delta_Array_Aggregate): Make Index_Type a constant. 2020-07-07 Piotr Trojanek * exp_aggr.adb (Expand_N_Delta_Aggregate): Use type of the delta base expression for the anonymous object of the delta aggregate. 2020-07-07 Javier Miranda * sem_util.ads (Interval_Lists): Reordering routine. * sem_util.adb (Interval_Lists): Reordering routines to keep them alphabetically ordered. 2020-07-07 Piotr Trojanek * sem_attr.adb (Resolve_Attribute): Do not call Check_Non_Static_Context. 2020-07-07 Arnaud Charlet * sem_elab.adb (Is_Guaranteed_ABE): Take into account null procedures. 2020-07-07 Piotr Trojanek * sem_ch5.adb (Analyze_Assignment): Reuse Is_Assignable. 2020-07-07 Piotr Trojanek * exp_spark.adb (Expand_SPARK_N_Attribute_Reference): Add scalar range checks for 'Update on arrays just like for 'Update on records. * sem_attr.adb (Analyze_Array_Component_Update): Do not set range checks for single-dimensional arrays. (Resolve_Attribute): Do not set range checks for both single- and multi- dimensional arrays. 2020-07-07 Piotr Trojanek * sem.ads (Sem): Fix description. 2020-07-07 Piotr Trojanek * sem_ch13.adb (Analyze_Relaxed_Parameter): Fix for protected entries. 2020-07-06 Piotr Trojanek * checks.adb (Apply_Scalar_Range_Check): Use Is_RTE. 2020-07-06 Bob Duff * libgnat/g-catiio.ads: Document newly supported format. Add ISO_Time constant, for convenience. * libgnat/g-catiio.adb (Image_Helper): New helper function to do all the formatting work, called by the two exported Image functions. Add support for "%:::z" here. Add a Time_Zone parameter used by the "%:::z" processing. This parameter is not used for the actual time zone computations; local time is always used for that, for ease of implementation reasons. It would make sense to use Append throughout this function, but that's a cleanup for another day. (Image): Modify these to pass the local time zone, or the specified time zone, as appropriate. 2020-07-06 Bob Duff * libgnat/g-catiio.ads: Change the regular expression that documents the allowed format to match what ISO-8601 allows. * libgnat/g-catiio.adb (Scan_Subsecond): Rewrite so it doesn't assume the subsecond comes last. (Parse_ISO_8601): Parse an optional subsecond, followed by an optional time zone, rather than making these alternatives to each other. 2020-07-06 Bob Duff * libgnat/g-catiio.adb (Parse_ISO_8601): Minor cleanups: Give some objects clearer names. Make some objects more local to where they are used. Remove some validity checks that can't fail, because some of the variables tested have been moved so they're not visible here. Anyway, Wrong_Syntax is about errors in the input, not data validity. Use Time_Zone_Seen instead of Local_Sign = ' ' to determine that a time zone indication was seen. We don't need to distinguish two different kinds of syntax error (End_Of_Source_Reached and Wrong_Syntax), so use Wrong_Syntax always. Remove comment, "Certain scanning scenarios may handle this exception on their own."; there are no such scenarios. 2020-07-06 Bob Duff * libgnat/g-catiio.ads, libgnat/g-catiio.adb (Image): New function. It might seem like the local-time Image should be implemented in terms of the Time_Zone Image, but that would be far harder to implement, so we do it the other way around. 2020-07-06 Thomas Quinot * libgnat/g-sechas.ads, libgnat/g-sechas.adb: Refactor to use Stream_Element_Array as the internal buffer type. * libgnat/g-shshco.adb: Adjust to use Stream_Element_Offset instead of Integer as the index in the internal state buffer. 2020-07-06 Gary Dismukes * doc/gnat_rm/implementation_defined_pragmas.rst, errout.ads, erroutc.adb, exp_ch4.adb, exp_ch6.adb, freeze.adb: Comment rewording/reformatting/typo fixes. Replace "ie." with "that is" in comment; "can not" -> "cannot", and remove an extraneous underscore in another comment. * gnat_rm.texi, gnat_ugn.texi: Regenerate. 2020-07-06 Javier Miranda * sem_util.ads (Interval_Lists.Aggregate_Intervals): New subprogram. * sem_util.adb (Has_Null_Others_Choice, Non_Static_Or_Null_Range, Interval_Lists.Aggregate_Intervals): New subprograms. (Is_Potentially_Unevaluated): Adding support to detect potentially unevaluated components of array aggregates. 2020-07-06 Bob Duff * libgnat/g-catiio.adb (Parse_ISO_8601): New name for Parse_ISO_8861_UTC. 8601 is the correct ISO standard number. Also, "UTC" was confusing. All Time values are represented in UTC, but the ISO 8601 date strings include a time zone. If a time zone was specified, call Ada.Calendar.Formatting.Time_Of instead of GNAT.Calendar.Time_Of, because the latter adjusts to the current time zone, whereas we want to use (just) the time zone specified in the ISO string. This allows us to pass Time_Zone instead to Time_Of, instead of adjusting by Local_Disp by hand. If no time zone was specified, call GNAT.Calendar.Time_Of as before. Use expanded names to clarify which Time_Of is being called. Remove redundant comment, and move nonredundant part of the commment to the spec. (Value): Minor: use "not in" instead of "or else". * libgnat/g-catiio.ads: Comment moved here. Correct the ISO standard number. * libgnat/g-calend.adb: Add ??? comments. * libgnat/a-calend.ads, libgnat/a-calend.adb: Update obsolete comments regarding the representation of type Time. Move the information about the epoch (year 2150) to the spec, and avoid uttering "2150" more than once. * libgnat/a-catizo.ads (Time_Offset): Add comment. 2020-07-06 Ed Schonberg * exp_ch5.adb (Find_Component): If the target type is a derived record type and the required component is a discriminant that is renamed in the derived type declaration, use the name of the original discriminant to locate the intended target component. 2020-07-06 Justin Squirek * sem_ch12.adb (Analyze_Associations): Add check for errors on the generic formal before continuing with instantiation. 2020-07-06 Arnaud Charlet * libgnat/a-nbnbin.ads, libgnat/a-nbnbin.adb, libgnat/a-nbnbin__gmp.adb: Use more Valid_Big_Integer. 2020-07-06 Piotr Trojanek * exp_util.ads (Get_Index_Subtype): Fix duplicate "Last". 2020-07-06 Ed Schonberg * sinfo.ads: Indicate that Field 1 of an N_Delta_Aggregate is unused. Previously it was erroneously labelled as holding an Expressions list, in analogy with other aggregate constructs, but there are no Expressions attached to this node syntactically or semantically. 2020-07-06 Piotr Trojanek * sem_attr.adb (Eval_Attribute): Check if constant has an initialization expression. 2020-07-06 Piotr Trojanek * exp_spark.adb (Expand_SPARK_N_Attribute_Reference): Apply scalar range checks. * sem_attr.adb (Resolve_Attribute): Do not set scalar range checks when resolving attribute Update. 2020-07-06 Gary Dismukes * sem_attr.adb (Analyze_Attribute, Attribute_Constrained): Issue a warning if the attribute prefix is a current instance reference within an aspect of a type or subtype. (Address_Checks): Replace test of Is_Object (Ent) with Is_Object_Reference (P) so that testing for current instances will be done. (Eval_Attribute): Add test for current instance reference, to ensure that we still fold array attributes when current instances are involved, since value prefixes are allowed for array attributes, and will now be excluded by Is_Object_Reference. * sem_util.ads (Is_Current_Instance_Reference_In_Type_Aspect): New exported query function. * sem_util.adb (Is_Object_Reference): Return False for the case where N is a current instance reference within an aspect_specification of a type or subtype (basically if the reference occurs within a predicate, invariant, or DIC aspect expression). (Is_Current_Instance_Reference_In_Type_Aspect): New function that tests whether a node is a reference to a current instance formal of a predicate, invariant, or Default_Initial_Condition (DIC) subprogram. 2020-07-06 Ed Schonberg * sem_res.adb (Resolve_Declare_Expression): New subprogram, to install the scope holding local declarations of the expression, before completing its resolution. (Resolve): For an Expression_With_Actions that comes from a source occurrence of a Declare_Expression, call new subprogram. 2020-07-06 Piotr Trojanek * sem_attr.adb (Analyze_Attribute): Reuse SPARK_Implicit_Load. 2020-07-06 Piotr Trojanek * sem_ch5.adb (Analyze_Loop_Parameter_Specification): Propagate exception when switch -gnatdk is used and no previous errors are present. * sem_eval.adb (Compile_Time_Known_Value, Is_In_Range): Likewise. * sem_warn.adb (Operand_Has_Warnings_Suppressed): Likewise. 2020-07-06 Richard Kenner * exp_unst.adb (Needs_Fat_Pointer): Don't check for formal. (Unnest_Subprogram): Use 'Unchecked_Access instead of 'Access when populating activation record. 2020-07-06 Eric Botcazou * exp_ch6.adb (Add_Simple_Call_By_Copy_Code): Rename parameter from Bit_Packed_Array to Force. (Expand_Actuals): Do not apply BIP processing if the subprogram is intrinsic. Adjust calls to Add_Simple_Call_By_Copy_Code and add one for In parameters whose actual is a CPP constructor call. 2020-07-06 Eric Botcazou * sem_attr.adb (Eval_Attribute): Do not apply range checks in the case of 'Pos applied to an integer type here. 2020-07-06 Ed Schonberg * sem_ch3.adb (Analyze_Object_Declaration): If the type is an Unchecked_Union, and the expression is an aggregate. complete the analysis and resolution of the aggregate, and treat like a regular object declaration, instead of as a renaming declarattion. 2020-07-06 Eric Botcazou * exp_ch9.adb (Is_Potentially_Large_Family): Add documentation. (Actual_Index_Expression): Use Entry_Index_Type. (Build_Entry_Count_Expression): Likewise. (Build_Find_Body_Index): Likewise. (Collect_Entry_Families): Likewise. Use directly the bounds of the index type to find out whether the family is large. (Entry_Index_Expression): Likewise. 2020-07-06 Piotr Trojanek * sem_res.adb (Resolve_Range): Resolve both low and high bounds with the range type. 2020-07-06 Arnaud Charlet * aspects.ads (Is_Representation_Aspect): Default_Component_Value is a representation aspect. * sem_ch13.adb (Check_Aspect_Too_Late, Rep_Item_Too_Late): Relax RM 13.1(10) rule wrt primitive operations for Ada 202x. 2020-07-06 Eric Botcazou * exp_aggr.adb (Aggr_Assignment_OK_For_Backend): Move to library level and use a new predicate Is_OK_Aggregate to recognize the aggregates suitable for direct assignment by the back-end. (Convert_Array_Aggr_In_Allocator): If neither in CodePeer mode nor generating C code, generate a direct assignment instead of further expanding if Aggr_Assignment_OK_For_Backend returns true. 2020-07-06 Gary Dismukes * sem_aux.adb: Add a with clause for Nlists. (Nearest_Ancestor): Test for the case of concurrent types (testing for both Is_Concurrent_Type and Is_Concurrent_Record_Type), and return the first ancestor in the Interfaces list if present (otherwise will return Empty if no interfaces). * sem_ch13.adb (Build_Predicate_Functions): Add a ??? comment about missing handling for adding predicates when they can be inherited from multiple progenitors. 2020-07-06 Arnaud Charlet * par-ch6.adb (P_Return_Object_Declaration): Set Has_Init_Expression flag. 2020-07-02 Eric Botcazou * debug.adb (d.K): Document new usage. * fe.h (Debug_Flag_Dot_KK): Declare. * gcc-interface/decl.c (gnat_to_gnu_field): Give an error when the component overlaps with the parent subtype, except with -gnatd.K. 2020-06-26 Eric Botcazou * exp_ch4.adb (Expand_Set_Membership): Expand the membership test using left associativity instead of right associativity. 2020-06-23 Eric Botcazou * gcc-interface/utils2.c (build_binary_op): Remove space. 2020-06-23 Eric Botcazou * gcc-interface/trans.c (gnat_to_gnu) : Minor tweaks. Call Has_Constrained_Partial_View on base type of designated type. 2020-06-23 Eric Botcazou * gcc-interface/utils.c (gnat_write_global_declarations): Output integral global variables first and the imported functions later. 2020-06-23 Eric Botcazou * gcc-interface/decl.c (elaborate_expression_1): When GNAT encodings are not used, do not create a variable for debug info purposes if the expression is itself a user-declared variable. 2020-06-23 Eric Botcazou * gcc-interface/ada-tree.h (DECL_RENAMED_OBJECT): Delete. * gcc-interface/decl.c (gnat_to_gnu_entity) : Always use the stabilized reference directly for renaming and create a variable pointing to it separately if requested. * gcc-interface/misc.c (gnat_print_decl): Adjust for deletion. * gcc-interface/trans.c (Identifier_to_gnu): Likewise.

(Expand_N_Object_Declaration): Call new subprogram. * sem_ch6.adb (Analyze_Function_Return): Returning a build-in-place unconstrained array type defer the full analysis of the returned object to avoid generating the corresponding constrained subtype; otherwise the bounds would be created in the stack and a dangling reference would be returned pointing to the bounds. 2020-06-19 Arnaud Charlet * libgnat/a-nbnbin.adb, libgnat/a-nbnbin.ads, libgnat/a-nbnbin__gmp.adb, libgnat/a-nbnbre.adb, libgnat/a-nbnbre.ads: Update spec according to AI12-0366. 2020-06-19 Piotr Trojanek * checks.ads: Remove excessive whitespace in declarations of functions for check suppression. 2020-06-19 Eric Botcazou * sem_ch7.adb (Hide_Public_Entities): Split handling of objects and subprograms, and do not reject the latter upfront in nested instance specs if there are no referencer subprograms at all.

(Build_Access_Subprogram_Wrapper): Examine aspect specifications of an Access_To_Subprogram declaration. If pre- or postconditions are declared for it, create declaration for subprogram wrapper and add the corresponding aspect specifications to it. Replace occurrences of the type name by that of the generated subprogram, so that attributes 'Old and 'Result can appear in a postcondition. * exp_ch3.adb (Build_Access_Subprogram_Wrapper_Body): Moved here from sem_prag.adb. * exp_ch3.ads (Build_Access_Subprogram_Wrapper_Body): Visible subprogram. * sem_prag.adb (Build_Access_Subprogram_Wrapper / _Body): Moved to sem_ch3.adb and exp_ch3.adb. 2020-06-17 Piotr Trojanek * atree.adb (Preserve_Comes_From_Source): Rewrite using Set_Comes_From_Source and Comes_From_Source, which enforce that the parameters are valid. * exp_ch4.adb, exp_ch5.adb, sem_ch12.adb, sem_ch6.adb, sem_res.adb: Rewrite using Preserve_Comes_From_Source. 2020-06-17 Arnaud Charlet * libgnat/a-nbnbin.ads, libgnat/a-nbnbre.ads: Remove obsolete comments. 2020-06-17 Gary Dismukes * aspects.ads (type Aspect_Id): Add Aspect_Static as a Boolean aspect, and update the Is_Representation_Aspect, Aspect_Names, and Aspect_Delay arrays. * exp_ch6.adb (Expand_Simple_Function_Return): In the case of a return for a static expression function, capture a copy of the expression of the return statement before it's expanded and reset its Analyzed flags. Then, just before leaving this procedure, if the expression was rewritten, set the Original_Node of the rewritten expression to the new copy and also set the Expression of the associated static expression function to designate that copy. This ensures that later copies of the expression made via New_Copy_Tree will fully copy all nodes of the expression tree. * inline.ads (Inline_Static_Expression_Function_Call): New procedure to evaluate and produce the result of a static call to a static expression function. * inline.adb: Add with and use for Sem_Res. (Establish_Actual_Mapping_For_Inlined_Call): New procedure extracted from code in Expand_Inlined_Call that traverses the actuals and formals of an inlined call and in some cases creates temporaries for holding the actuals, plus establishes an association between formals and actuals (via the Renamed_Object fields of the formals). (Formal_Is_Used_Once): Function removed from Expand_Inlined_Call and now nested in the above procedure. (Expand_Inlined_Call): Code for doing the formal/actual traversal is moved to Create_Actual_Temporaries and replaced with a call to that new procedure. (Inline_Static_Expression_Function_Call): New procedure to evaluate a static call to a static expression function, substituting actuals for their corresponding formals and producing a fully folded and static result expression. The function has subsidiary functions Replace_Formal and Reset_Sloc that take care of doing the mapping of formals to actuals and resetting the Slocs of subnodes of the mapped expression to that of the call so errors will be flagged on the call rather than function. * sem_ch6.adb (Analyze_Expression_Function): In the case of a static expression function, perform an additional preanalysis of the function's expression to ensure that it's a potentially static expression (according to the requirements of 6.8(3.2/5-3.4/5)), and issue an error if it's not. The global flag Checking_Potentially_Static_Expression is set and unset around this checking. * sem_ch13.adb (Analyze_Aspect_Static): New procedure to enforce selected requirements of the new aspect Static on expression functions, including checking that the language version is Ada_2020 and that the entity to which it applies is an expression function whose formal parameters are of a static subtype and have mode 'in', its result subtype is a static subtype, and it has no pre- or postcondition aspects. A ??? comment is added to indicate the need for adding checking that type invariants don't apply to the result type if the function is a boundary entity. (Analyze_One_Aspect): Call Analyze_Aspect_Static for aspect Static. * sem_elab.adb (Build_Call_Marker): Return without creating a call marker when the subprogram is a static expression function, since no ABE checking is needed for such functions. * sem_eval.ads (Checking_Potentially_Static_Expression): New function to return whether the checking for potentially static expressions is enabled. (Set_Checking_Potentially_Static_Expression): New procedure to enable or disable checking of potentially static expressions. * sem_eval.adb (Checking_For_Potentially_Static_Expression): New global flag for determining whether preanalysis of potentially static expression is being done, which affects the behavior of certain static evaluation routines. (Checking_Potentially_Static_Expression): New function to return whether the checking for potentially static expressions is enabled. (Eval_Call): When evaluating a call within a static expression function with checking of potentially static expression functions enabled, substitutes a static value in place of the call to allow folding of the expression. (Eval_Entity_Name): When evaluating a formal parameter of a static expression function with checking of potentially static expression functions enabled, substitutes a static value in place of the reference to the formal to allow folding of the expression. (Set_Checking_Potentially_Static_Expression): New procedure to enable or disable checking of potentially static expressions. * sem_res.adb (Resolve_Call): Test for a recursive call occurring within a static expression function and issue an error for such a call. Prevent the establishment of a transient scope in the case this is a call to a (string-returning) static expression function. When calling a static expression function, if no error has been posted on the function, call Inline_Static_Expression_Function_Call to convert the call into its equivalent static value. * sem_util.ads (Is_Static_Expression_Function): New function returning whether the subprogram entity passed to it is a static expression function. (Is_Static_Expression_Function_Call): New function to determine whether the call node passed to it is a static call to a static expression function. * sem_util.adb (Compile_Time_Constraint_Error): Suppress compile-time Constraint_Error reporting when checking for a potentially static expression. (Is_Static_Expression_Function): New function returning whether the subprogram entity passed to it is a static expression function by testing for the presence of aspect Static. (Has_All_Static_Actuals): New function in Is_Static_Expression_Function_Call that traverses the actual parameters of a function call and returns True only when all of the actuals are given by static expressions. In the case of a string-returning function, we call Resolve on each actual to ensure that their Is_Static_Expression flag properly reflects whether they're static, to allow suppressing creation of a transient scope within Resolve_Call. A prominent ??? comment is added to explain this rather unconventional call to Resolve. (Is_Static_Expression_Function_Call): New function that determines whether a node passed to it is a call to a static expression function all of whose actual parameters are given by static expressions. 2020-06-17 Eric Botcazou * exp_ch4.adb (Optimize_Length_Comparison): New local variable to record whether this may be a dynamic superflat case. (Is_Optimizable): Accept 0 as lower bound and set it in this case, but return false if the operand is not a length too. (Rewrite_For_Equal_Lengths): New procedure.

(P_Unparen_Cond_Expr_Etc): New name for P_Unparen_Cond_Case_Quant_Expression which was missing one case in its name (iterated component association), and we're adding a new case (declare expression), so lets use "Etc" instead of trying to pack all those things into the name. Add call to P_Declare_Expression, and check for missing parens. (P_Expression_If_OK, P_Expression_Or_Range_Attribute_If_OK): Add Tok_Declare. * par.adb (P_Basic_Declarative_Items): Add parameter Declare_Expression so we can tailor the error message about incorrect bodies. (P_Case_Expression): Move to body. * par-ch3.adb (P_Basic_Declarative_Items): Tailor the error message about incorrect bodies. * par-ch7.adb (P_Package): Pass Declare_Expression => False to P_Basic_Declarative_Items. * sem.ads (In_Declare_Expr): Counter used to determine whether we are analyzing a declare_expression. Needed to give errors about things that are not allowed in declare_expression, such as the 'Access attribute. * sem.adb (Do_Analyze): Save/restore In_Declare_Expr. * sem_ch4.adb (Analyze_Expression_With_Actions): Give this node its own scope. That seems better in general, but it is necessary for declare_expressions. For example, an identifier declared in a declare_expression should not clash with the same identifier in an outer scope. If this is a declare_expression, indicated by Comes_From_Source, then check legality rules, and incr/decr In_Declare_Expr. * sem_aggr.adb (Resolve_Aggregate): Allow an applicable index constraint for a declare_expression, so if its expression is an array aggregate, it can have "others => ...". * sem_attr.adb (Analyze_Access_Attribute): Disallow these attributes in declare_expressions. Add comment to make it clear that Unrestricted_Access is included. * sinfo.ads, sinfo.adb, atree.ads, atree.adb: Remove the now-incorrect comment in sinfo.ads that says N_Expression_With_Actions has no proper scope. Add 17-parameter versions of Nkind_In. Remove the 16-parameter versions of Nkind_In. 2020-06-16 Arnaud Charlet * sem_aux.ads, sem_aux.adb (Is_Record_Or_Limited_Type): New function. * exp_ch4.adb, sem_ch4.adb (Analyze_Membership_Op, Expand_Set_Membership.Make_Cond): Choose between primitive and predefined equality for membership tests. 2020-06-16 Ed Schonberg * sem_warn.adb (Warn_On_Overlapping_Actuals): Simplify code and implement AI12-0216 which clarifies the conditions under which overlapping actuals in a call are illegal. If proper warnings are enabled, GNAT also emits warnings in legal cases of overlopping actuals. 2020-06-16 Eric Botcazou * freeze.adb (Freeze_Expression): Stop climbing the parent chain at a N_{Case,If}_Expression node for a type or an entity that does not come from source. 2020-06-16 Steve Baird * snames.ads-tmpl: Define names of the three new aspects. * aspects.ads: Define the three new aspects. * sem_util.ads, sem_util.adb, sem_dim.adb: Move the function String_From_Numeric_Literal from being declared in the body of package Sem_Dim to being declared in the visible part of package Sem_Util. * sem_ch13.ads, sem_ch13.adb: Declare new visible procedure Validate_Literal_Aspect. This is where most of the legality checking occurs for an aspect specification for one of the three new aspects, as well as resolution of the subprogram named in the aspect specification. Follow example of other aspects (e.g., Validate_Literal_Aspect is called in much the same way as Validate_Iterable_Aspect in Analyze_Aspects_At_Freeze_Point; a small amount of legality checking is performed in Analyze_One_Aspect in much the same way as for Default_Value or Default_Component_Value aspects). Most of the work is done in Validate_Literal_Aspect. * contracts.adb (Add_Contract_Item): Call Validate_Literal_Aspect in much the same way that Validate_Iterable_Aspect was already being called. * sem_res.adb (Resolve): Rewrite a literal as a call if it is a user-defined literal. This is where the dynamic semantics of the 3 new aspects are implemented. * sem_ch6.adb (Fully_Conformant_Expressions): Two numeric literals that have different text but the same value (e.g., 12345 and 12_345) do not conform if they are user-defined literals. Introduce a new function User_Defined_Numeric_Literal_Mismatch to avoid duplication in making this check. * sem_type.adb (Has_Compatible_Type): A numeric literal can be compatible with a non-numeric type (and a string literal can be compatible with a non-string type) if it can be interpreted as a user-defined literal. 2020-06-16 Arnaud Charlet * sem_aggr.adb (Resolve_Extension_Aggregate): Fix implementation of AI05-0115 by checking the correct type. 2020-06-16 Arnaud Charlet * sem_ch6.adb (Analyze_Subprogram_Specification): Generate error message for functions returning interfaces. 2020-06-16 Piotr Trojanek * sem_ch13.adb (Membership_Entry): Relax assertion to also recognize qualified identifiers. 2020-06-16 Piotr Trojanek * exp_util.adb (Evaluate_Name): Force evaluation of operators. 2020-06-16 Arnaud Charlet * sem_ch4.adb (Analyze_Membership_Op): Reset entity of equality nodes for membership tests with singletons. (Analyze_User_Defined_Binary_Op): Always perform the analysis since nodes coming from the expander also may refer to non standard operators as part of membership expansion. * exp_ch4.adb (Expand_Set_Membership.Make_Cond): Reset entity of equality node. * sem_type.ads: Fix typo in comment. 2020-06-16 Ghjuvan Lacambre * sem_attr.adb (Analyze_Attribute): Add Check_Not_Incomplete_Type call. 2020-06-16 Gary Dismukes * sem_ch6.adb: Add closing paren in a comment. * sem_util.adb: Correct comment typo (aggreate => aggregate). 2020-06-16 Javier Miranda * sem_prag.adb (Process_Restrictions_Or_Restriction_Warnings): Code cleanup. 2020-06-16 Eric Botcazou * freeze.adb (In_Expanded_Body): Remove unreachable code. (Freeze_Expression): Rename a couple of local variables. In the case of an expanded body, also freeze locally the entities declared in a nested block. 2020-06-16 Eric Botcazou * sem_ch4.adb (Transform_Object_Operation): Document that it may be partially destructive for the parent of the node. (Try_Object_Operation): Undo the changes made above on failure. 2020-06-16 Javier Miranda * restrict.adb (Global_No_Tasking): Adding Targparm.Restrictions_On_Target Fixes regressions with zfp. 2020-06-16 Ed Schonberg * freeze.adb: (Freeze_Expression, In_Expanded_Body): Treat the generated body of an expression function like other bodies generated during expansion (e.g. stream subprograms) so that those bodies are not treated as freezing points. Handle properly other global references in such completions. 2020-06-16 Piotr Trojanek * sem_ch8.adb (Analyze_Object_Renaming): Remove trivially useless initialization of Is_Object_Reference. * sem_util.adb (Is_Object_Reference): Simplify detection of binary and unary operators; literally implement rules about aggregates and qualified expressions; recognize string literals as object references. 2020-06-16 Eric Botcazou * sem_ch12.adb (Validate_Derived_Type_Instance): Reword error message for 12.5.1(8) subclause and add secondary message if the incompatibility comes from the predicates. * sem_ch3.adb (Check_Constraining_Discriminant): New procedure to give the error required by the 3.7(15) subclause. Mention "statically" in the error message and add secondary message if the incompatibility comes from the predicates. (Build_Derived_Concurrent_Type): Call it when a new discriminant constrains an old one. (Build_Derived_Record_Type): Likewise. * sem_eval.ads (Predicates_Compatible): Declare. * sem_eval.adb (Predicates_Compatible): New function to implement the compatibility of predicates specified by the 4.9.1 clause. (Subtypes_Statically_Compatible): Call it. 2020-06-15 Eric Botcazou * sem_eval.ads (Predicates_Match): Fix description. * sem_eval.adb (Predicates_Match): Rewrite. 2020-06-15 Ed Falis * Makefile.rtl: Change name of hie/g-io__vxworks-ppc-cert.adb. 2020-06-15 Arnaud Charlet * sem_ch8.adb (Premature_Usage): Add support for subtype references and replace set of if-then-else by a case statement. 2020-06-15 Piotr Trojanek * sem_prag.adb (Analyze_Depends_In_Decl_Part, Analyze_Global_In_Decl_Part): Bring back task discriminants for analysis of the Global/Depends contracts; add comments. 2020-06-15 Eric Botcazou * einfo.ads (Return_Applies_To): Document special usage for E_Block. * einfo.adb (Write_Field8_Name): Write it for E_Block too. * exp_ch4.adb (Expand_N_Type_Conversion): Remove implementation of the check prescribed by AI05-0073. * exp_ch6.adb (Apply_CW_Accessibility_Check): New procedure to apply the check prescribed by AI95-344 extracted from... (Expand_N_Extended_Return_Statement): Apply the check prescribed by AI95-344 to the expression, if present. Suppress only access checks when analyzing the rewritten result. (Expand_Simple_Function_Return): ...here. Rename local variable. Call Apply_CW_Accessibility_Check to apply the check prescribed by AI95-344, but do not do it for the simple return statement generated by the expansion of an extended return statement. Apply the check prescribed by AI05-0073 to all functions returning anonymous access type designating a specific tagged type, but not if the expression was null or tag checks are suppressed for the type, and use Not In operator rather than comparing the tags explicitly. * sem.adb (Analyze): Handle all Suppress values. * sem_ch6.adb (Analyze_Function_Return): Do not explicitly apply predicate checks in the case of an extended return statement. Do not apply an implicit conversion to the anonymous access result type in the case of the simple return statement generated by the expansion of an extended return statement. (New_Overloaded_Entity): Small comment tweak. * treepr.adb (Print_Node): Fix typo in flag string. 2020-06-15 Bob Duff * exp_put_image.ads, exp_put_image.adb (Image_Should_Call_Put_Image): New function to determine whether the call to Put_Image should be generated. (Build_Image_Call): New procedure to generate the call to Put_Image. * exp_imgv.adb (Expand_Image_Attribute): Use underlying types to bypass privacy (only in Ada 2020). If Image_Should_Call_Put_Image is True (which happens only in Ada 2020), then call Build_Image_Call. * rtsfind.ads, rtsfind.adb: Add the necessary declarations in Ada.Strings.Text_Output.Buffers. * sem_attr.adb (Check_Image_Type): Enable the Ada 2020 case. * libgnat/a-stoufo.ads, libgnat/a-stoufo.adb: Use the less restrictive type that allows newline characters. 2020-06-15 Gary Dismukes * exp_ch9.ads (Build_Master_Declaration): Add commas. * exp_ch9.adb (Build_Master_Entity): Spelling fix ("build" => "built"). (Build_Task_Activation_Call): Fix word order. 2020-06-15 Arnaud Charlet * libgnat/a-nbnbin.ads (Big_Positive, Big_Natural): Fix predicate. 2020-06-15 Piotr Trojanek * sem_ch13.adb (Analyze_Aspect_Relaxed_Initialization): Fix dealing with scopes on subprogram bodies that act as specs. * sem_util.adb (Has_Relaxed_Initialization): Fix trivial mistake. 2020-06-15 Javier Miranda * restrict.ads (Set_Global_No_Tasking, Global_No_Tasking): New subprograms. * restrict.adb (Set_Global_No_Tasking, Global_No_Tasking): New subprograms. * sem_ch3.adb (Access_Definition): Do not skip building masters since they may be required for BIP calls. (Analyze_Subtype_Declaration): Propagate attribute Is_Limited_Record in class-wide subtypes and subtypes with cloned subtype attribute; propagate attribute Is_Limited_Interface. * sem_ch6.adb (Check_Anonymous_Return): Do not skip building masters since they may be required for BIP calls. Use Build_Master_Declaration to declare the _master variable. (Create_Extra_Formals): Add decoration of Has_Master_Entity when the _master formal is added. * exp_ch3.adb (Init_Formals): Adding formal to decorate it with attribute Has_Master_Entity when the _master formal is added. (Build_Master): Do not skip building masters since they may be required for BIP calls. (Expand_N_Object_Declaration): Ensure activation chain and master entity for objects initialized with BIP function calls. * sem_prag.adb (Process_Restrictions_Or_Restriction_Warnings): Adding support to detect and save restriction No_Tasking when set in the run-time package System or in a global configuration pragmas file. * sem_util.adb (Current_Entity_In_Scope): Overload this subprogram to allow searching for an entity by its Name. * sem_util.ads (Current_Entity_In_Scope): Update comment. * exp_ch4.adb (Expand_N_Allocator): Do not skip building masters since they may be required for BIP calls. * exp_ch6.ads (Might_Have_Tasks): New subprogram. * exp_ch6.adb (Make_Build_In_Place_Call_In_Allocator): Add support for BIP calls returning objects that may have tasks. (Make_Build_In_Place_Call_In_Allocator): Build the activation chain if the result might have tasks. (Make_Build_In_Place_Iface_Call_In_Allocator): Build the class wide master for the result type. (Might_Have_Tasks): New subprogram. (Needs_BIP_Task_Actuals): Returns False when restriction No_Tasking is globally set. * exp_ch9.ads (Build_Master_Declaration): New subprogram. * exp_ch9.adb (Build_Activation_Chain_Entity): No action performed when restriction No_Tasking is globally set. (Build_Class_Wide_Master): No action performed when restriction No_Tasking is globally set; use Build_Master_Declaration to declare the _master variable. (Build_Master_Declaration): New subprogram. (Build_Master_Entity): No action performed when restriction No_Tasking is globally set; added support to handle transient scopes and _finalizer routines. (Build_Master_Renaming): No action performed when restriction No_Tasking is globally set. (Build_Task_Activation_Call): Skip generating the call when the chain is an ignored ghost entity. (Find_Master_Scope): Generalize the code that detects transient scopes with master entity. * einfo.ads (Has_Nested_Subprogram): Minor comment reformatting. 2020-06-15 Arnaud Charlet * sem_attr.adb (Eval_Attribute): Protect against previous errors. * sem_ch13.adb (Analyze_Aspect_Default_Value): Remove redundant error checking, handling in Analyze_Aspect_Specifications. (Analyze_Aspect_Specifications): Refine error messages on Default_[Component_]Value. (Check_Aspect_Too_Late): New procedure. (Rep_Item_Too_Late.Is_Derived_Type_With_Constraint): Remove, dead code. * aspects.ads (Is_Representation_Aspect): Default_Value is a representation aspect. 2020-06-15 Arnaud Charlet * libgnat/a-wichha.ads, libgnat/a-wichha.adb, libgnat/a-wichun.ads, libgnat/a-wichun.adb (Is_Basic, To_Basic): New. * libgnat/s-utf_32.ads, libgnat/s-utf_32.adb (Is_UTF_32_Basic, To_UTF_32_Basic, Decomposition_Search): New subprograms. (Unicode_Decomposition): New table. 2020-06-15 Gary Dismukes * exp_ch6.adb (Add_Call_By_Copy_Code): In the case of a view conversion passed to a scalar out-mode parameter where the formal has Default_Value set, declare the copy temp with the base type of the formal's subtype and initialize the copy temp with the actual's value. 2020-06-15 Justin Squirek * exp_ch4.adb (Expand_N_Case_Expression): Set default value for Target to silence potential warnings. (Expand_N_If_Expression): Add calculation to check when the if expression is used directly in the context of an actual of an anonymous access type and add a special path to force expansion of the if expression in this case. * exp_ch6.adb (Expand_Branch): Generate an assignment to the level temporary for a given branch. (Expand_Call_Helper): Add expansion to allow for creating a temporary to store associated accessiblity levels on each branch of the conditional expression. Also perform expansion of function calls into expressions with actions, and fixup references to N with Call_Node. (Insert_Level_Assign): Move through nested conditional expressions to each branch. * sem_util.ads, sem_util.adb (Is_Anonymous_Access_Actual): Added to detect when to force expansion of if expressions. 2020-06-15 Piotr Trojanek * sem_prag.adb (Analyze_Depends_In_Decl_Part, Analyze_Global_In_Decl_Part): Do not install task discriminants for analysis of the Global/Depends contracts. 2020-06-15 Piotr Trojanek * contracts.adb (Analyze_Object_Contract): Do not expect Global/Depends on single protected units. 2020-06-15 Justin Squirek * sem_res.adb (Valid_Conversion): Add missing condition to trigger proper static accessiblity failiures when the target type is an anonymous access. 2020-06-15 Piotr Trojanek * exp_ch6.adb (Expand_Call_Helper): Replace repeated Ekind with Ekind_In. 2020-06-15 Piotr Trojanek * exp_ch6.adb, sem_util.adb: Remove excessive parents, especially since they don't make the code any easier to read. 2020-06-15 Piotr Trojanek * aspects.ads (Aspect_Id): Add Aspect_Relaxed_Initialization. (Implementation_Defined_Aspect): Add new aspect. (Aspect_Argument): Add new aspect with Optional_Expression argument. (Is_Representation_Aspect): Add new aspect as a non-representation one. (Aspect_Names): Add name for the new aspect. (Aspect_Delay): Add new aspect as a non-delayed one. * sem_ch3.adb: Minor reformatting. * einfo.ads, einfo.adb (Is_Relaxed_Initialization_State): New query; reuses existing code for querying abstract state options. * exp_attr.adb (Expand_N_Attribute_Reference): For now ignore attribute 'Initialized. * sem_attr.adb (Analyze_Attribute_Old_Result): Allow attribute 'Result to be used in the aspect Relaxed_Initialization expression. (Analyze_Attribute): Analyze attribute 'Initialized; based on existing code for attribute 'Valid_Scalars. (Eval_Attribute): Do not expect attribute 'Initialized, just like attribute 'Valid_Scalars is not expected. * sem_ch13.adb (Analyze_Aspect_Relaxed_Initialization): New routine. (Analyze_Aspect_Specifications): Analyze new aspect in a dedicated routine. (Check_Aspect_At_Freeze_Point): Do not expect new aspect. * sem_prag.adb (Analyze_Abstract_State): Support option Relaxed_Initialization on abstract states. * sem_util.ads, sem_util.adb (Has_Relaxed_Initialization): New query for the GNATprove backend. * snames.ads-tmpl (Snames): Add Name_Ids for the new aspect and attribute; add an Attribute_Id for the new attribute. 2020-06-15 Bob Duff * exp_put_image.adb, libgnat/s-putima.adb, libgnat/s-putima.ads, rtsfind.ads: Enable Put_Image if Is_Access_Subprogram_Type (Typ). Remove comment saying it's disabled in that case. Rename Put_Image_Access_Prot to be Put_Image_Access_Prot_Subp to clarify that we're talking about access-to-subprogram, not access-to-protected-object. 2020-06-15 Bob Duff * sem_attr.adb (Check_Image_Type): New procedure for checking the type, depending on language version. Disable the Ada 2020 support until the corresponding expander work is done. (Analyze_Image_Attribute): Call Check_Image_Type. Rearrange the code to be simplier and more logical. When P_Type is modified, modify P_Base_Type accordingly. * sem_util.adb (Is_Object_Image): Do not return False if the prefix is a type. X'Image should be considered an image of an object iff X is an object (albeit illegal pre-2020 if nonscalar). 2020-06-15 Bob Duff * libgnat/s-putima.ads, libgnat/s-putima.adb (Put_Image_Access_Subp, Put_Image_Access_Prot): New procedures for printing access-to-subprogram objects. Remove an explicit " ", because Put_Image includes the annoying leading blank. * rtsfind.ads: Add new procedures in s-putima. * exp_put_image.adb: Call new procedures as appropriate. 2020-06-15 Bob Duff * exp_imgv.adb (Expand_Image_Attribute): Allow private types. Put_Image generates Image for numeric types, and private types whose full type is numeric. This requires the Conversion_OK flag for integer and floating-point types. For fixed point, we need the extra conversion. * exp_put_image.adb (Build_Elementary_Put_Image_Call): Remove special handling of real types. (Enable_Put_Image): Enable for reals. 2020-06-15 Bob Duff * exp_attr.adb (Put_Image): Use underlying type for strings. Remove unchecked union processing. * exp_put_image.adb (Tagged_Put_Image_Enabled): Use -gnatd_z to enable default Put_Image for tagged types. This allows testing that feature. (Build_String_Put_Image_Call): Set Conversion_OK flag. (Make_Component_List_Attributes): Remove unchecked union processing. (Enable_Put_Image): Disable for unchecked unions. Enable for nonscalar types (which were mistakenly disabled in earlier changes). * debug.adb: Document -gnatd_z switch. * libgnat/s-putima.adb (Put_Image_String, Put_Image_Wide_String, Put_Image_Wide_Wide_String): Double double-quote characters. Forget about special handling of control characters for now -- that's rare enough to not be a priority, and it's not clear what the right thing to do is anyway. * namet.adb: Minor: Improve debugger-friendliness. * sinfo.ads: Minor: Add "???" comment. 2020-06-15 Piotr Trojanek * sem_util.ads, sem_util.adb (Is_Renaming_Declaration): Remove. 2020-06-15 Ed Schonberg * freeze.adb (Freeze_Expression): When traversing the tree looking for the proper insertion point for the freeze node of an entity that is declared in an outer scope, set the candidate subprogram body node properly. Previous code has an off-by-one error. 2020-06-15 Eric Botcazou * exp_attr.adb (Expand_N_Attribute_Reference) : Do not do superfluous work. Add the condition (X'Size /= 0) on both paths and turn binary AND into short-circuit AND THEN. 2020-06-15 Steve Baird * sem_attr.adb (Analyze_Attribute): In the Loop_Entry case, replace a call to Statically_Denotes_Object with a call to Statically_Names_Object and clean up the preceding comment. 2020-06-15 Eric Botcazou * sem_res.adb (Resolve_Set_Membership): Remove local variable. In the non-overloaded case, call Intersect_Types on the left operand and the first alternative to get the resolution type. But test the subtype of the left operand to give the warning. 2020-06-12 Steve Baird * sem_res.adb (Valid_Conversion): The simpler cases of violations of the aforementioned 8.6 rule are already handled correctly. These include cases where the operand of the type conversion is an access parameter or a stand-alone object of an anonymous access type. Add code to detect violations where the operand of the type conversion is an access discriminant whose accessibility level is tied to one of the other simpler cases. This is implemented in a new function, Valid_Conversion.Is_Discrim_Of_Bad_Access_Conversion_Argument, which is called in place of the previous test. 2020-06-12 Bob Duff * exp_attr.adb (Put_Image): Remove assertion. This assertion is False in mixed-Ada-version programs. * exp_put_image.adb (Tagged_Put_Image_Enabled): New flag to make it easy to experiment with Put_Image on tagged types. False in this version. (Enable_Put_Image): Enable in pre-2020. Workarounds: Disable for tagged types if Tagged_Put_Image_Enabled is False. Disable for access-to-subprogram types. Disable if errors have been detected, or Sink is unavailable. (Preload_Sink): Move all conditionals here, from Sem_Ch10, so they can be nearby related code in Enable_Put_Image. Load Sink only if we have seen a tagged type. This removes the dilemma about calling Preload_Sink when compiling the compiler, which caused unwanted dependences. * exp_put_image.ads (Preload_Sink): New formal Compilation_Unit, needed to move all conditionals here, from Sem_Ch10. * libgnat/a-stouut.adb (Put_UTF_8): Make this suitable for inlining, so we don't get warnings about inlining in some tests. And so it can be inlined! * opt.ads (Tagged_Seen): New flag (see Preload_Sink). * scng.adb (Scan): Set new Tagged_Seen flag. * sem_ch10.adb (Analyze_Compilation_Unit): Move conditionals and comments regarding Preload_Sink into Preload_Sink. 2020-06-12 Arnaud Charlet * sem_res.adb (Resolve_Actuals): Check for AI12-0074. 2020-06-12 Olivier Hainque * libgnat/s-secsta.ads (Memory_Alignment): New constant, memory alignment for chunks and allocated blocks. Initialize to Standard'Maximum_Alignment * 2.

The first two were taken from sem_attr.adb. The term "statically names" is defined in the Ada RM and the new function Statically_Names_Object is intended to reflect that definition, or more precisely, as described in a comment in the code, to reflect the expected future definition of that term. * sem_attr.adb: Delete functions Statically_Denotes_Object and Statically_Denotes_Entity; these two functions have been moved to package Sem_Util. Replace call to Statically_Denotes_Object with a call to Statically_Names_Object as per AI12-0217 (a binding interpretation, so no Ada_Version check). * exp_ch9.adb (Expand_Entry_Barrier.Is_Simple_Barrier): Change name of function (it was previously Is_Simple_Barrier_Name) because the function should return True in the case of a static expression; implement this requirement. Change function to include a call to Statically_Names_Object so that, for Ada_2020 and later, it will return True for appropriate subcomponent names. (Expand_Entry_Barrier.Is_Pure_Barrier): Handle N_Indexed_Component and N_Selected_Component cases by calling Statically_Names_Object. (Expand_Entry_Barrier): Reorganize to treat Simple_Barriers and Pure_Barriers more uniformly. Prevent cascaded errors. 2020-06-12 Ed Schonberg * sem_ch12.adb (Find_Matching_Actual): Add guard on search loops to detect a compilation error when using a compiler built without assertions. (Instantiate_Formal_Subprogram): Create a new subprogram name for the actual only if formal has contract aspects and expansion is enabled. 2020-06-12 Eric Botcazou * exp_aggr.adb: Add with and use clauses for Sem_Mech. (Get_Base_Object): New function to get the base object of a node. (In_Place_Assign_OK): Add Target_Object parameter. Deal with a qualified expression on entry. Remove short-circuit for array aggregates with a single "others" choice. Do not look into the components of the aggregate if the parent is an allocator. (Check_Component): Add T_OK parameter and rewrite. (Safe_Component): Invoke Check_Component with T_OK set to False. (Convert_To_Assignments): Try to use an in-place assignment for any target; for that, call Get_Base_Object on the target and pass the result to In_Place_Assign_OK. (Expand_Array_Aggregate): Use Parent_Kind and Parent_Node more consistently. For an assignment, call Get_Base_Object on the target and pass the result to In_Place_Assign_OK. 2020-06-12 Dmitriy Anisimkov * socket.c (__gnat_minus_500ms): Use GetVersionEx to detect Windows Server version. * libgnat/g-sothco.ads (Minus_500ms_Windows_Timeout): Remade to Boolean constant. * libgnat/g-socket.adb (Set_Socket_Option): Use Minus_500ms_Windows_Timeout constant instead of function call. 2020-06-12 Arnaud Charlet * libgnat/a-coinho.ads, libgnat/a-coinho.adb, libgnat/a-coinho__shared.ads, libgnat/a-coinho__shared.adb (Swap): New procedure. 2020-06-12 Arnaud Charlet * exp_ch6.adb (Expand_N_Subprogram_Declaration): Do nothing for a subprogram declared in a protected body. * exp_ch9.ads, exp_ch9.adb (Build_Private_Protected_Declaration): Moved to sem_ch6.adb.

Propagate Predicate attributes from the full to the private view. * sem_ch9.adb (Analyze_Protected_Type_Declaration): Likewise.

Fix the "raise Program_Error" message, which was backwards. 2020-06-09 Bob Duff * bindo-graphs.adb (Add_Edge_Kind_Check): Add the Image of the old and new Kinds to the raise Program_Error message. 2020-06-09 Eric Botcazou * sem_ch3.adb (Is_Visible_Component): Do not special-case bodies of instances. 2020-06-09 Arnaud Charlet * exp_ch4.adb (Expand_N_In): Fix handling of null exclusion. 2020-06-09 Ed Schonberg * sem_ch12.adb (Check_Shared_Variable_Control_Aspects): Require exact match between formal and actual for aspects Atomic, Atomic_Component, Volatile, and Volatile_Components. 2020-06-09 Bob Duff * doc/gnat_ugn/gnat_utility_programs.rst: Add documentation for the --no-separate-return switch of gnatpp. 2020-06-09 Arnaud Charlet * sem_warn.adb (Warn_On_Constant_Valid_Condition): Add proper warning tag. 2020-06-09 Arnaud Charlet * sem_type.adb (Covers): Fix implementation of AI05-0149. * sem_res.adb: Fix typo. 2020-06-09 Ed Schonberg * exp_ch9.adb (Build_Master_Renaming): Make name in renaming declaration unique by adding a numeric suffix, to prevent accidental name conflict when several instantiations of a package containing an access_to_incomplete type that designate tasks appear in the same scope. 2020-06-09 Piotr Trojanek * libgnarl/a-synbar.ads, libgnarl/a-synbar.adb, libgnarl/a-synbar__posix.ads, libgnarl/a-synbar__posix.adb (Ada.Synchronous_Barriers): Annotate with SPARK_Mode => Off. 2020-06-09 Arnaud Charlet * sem_eval.adb (Eval_Relational_Op, Eval_String_Literal, Eval_Type_Conversion): Relax rules on relational operators and type conversions of static string types. 2020-06-09 Arnaud Charlet * sem_util.ads, sem_util.adb (Is_Partially_Initialized_Type): Take Default_Value and Default_Component_Value into account. * sem_ch3.adb (Analyze_Object_Declaration): Update comment. 2020-06-09 Bob Duff * bindo-graphs.adb (Add_Edge_Kind_Check): Disable failing part of the assertion. 2020-06-08 Steve Baird * sem_prag.adb (Analyze_Pragma.Set_Ravenscar_Profile): Add appropriate call to Set_Restriction_No_Dependence if Ada_Version >= Ada2012 and Profile is either Ravenscar or a GNAT-defined Ravenscar variant (i.e., not Jorvik). 2020-06-08 Arnaud Charlet * sem_ch5.adb: Fix typo. * sem_ch8.adb (Analyze_Renamed_Primitive_Operation): Check that the prefix of a prefixed view must be renamable as an object. 2020-06-08 Arnaud Charlet * sem_cat.ads: Fix typo. * sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type): Add handling of N_Attribute_Definition_Clause. * sem_ch13.adb (Analyze_Attribute_Definition_Clause): Call Validate_Remote_Access_To_Class_Wide_Type for Storage_Size and Storage_Pool. * sem_attr.adb, exp_ch4.adb: Update comments. 2020-06-08 Justin Squirek * sem_ch4.adb (Analyze_One_Call): Add extra condition to the predicate for deciding when a given controlled call is visible. 2020-06-08 Piotr Trojanek * exp_spark.adb (Expand_SPARK_N_Attribute_Reference): Port changes in frontend expander. 2020-06-08 Piotr Trojanek * sem_ch13.adb (All_Membership_Choices_Static): Fix style. 2020-06-08 Steve Baird * libgnat/s-rident.ads: Add Jorvik to the Profile_Name enumeration type. Add an element for Jorvik to the array aggregate that is the initial value of the constant Profile_Info. * targparm.adb (Get_Target_Parameters): Handle "pragma Profile (Jorvik);" similarly to "pragma Profile (Ravenscar);". * snames.ads-tmpl: Declare Name_Jorvik Name_Id. Unlike Ravenscar, Jorvik is not a pragma name and has no corresponding element in the Pragma_Id enumeration type; this means that its declaration must not occur between those of First_Pragma_Name and Last_Pragma_Name. * sem_prag.adb (Analyze_Pragma): Add call to Set_Ravenscar_Profile for Jorvik, similar to the existing calls for Ravenscar and the GNAT Ravenscar variants. 2020-06-08 Arnaud Charlet * sem_ch8.adb (Analyze_Object_Renaming): Update Get_Object_Name to go through N_Qualified_Expression and N_Type_Conversion. Fix another case of wrong usage of E_Anonymous_Access_Type instead of Anonymous_Access_Kind. * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): Work on the original node. (Is_Aliased_View): Take into account N_Qualified_Expression. 2020-06-08 Arnaud Charlet * sem_eval.adb (Eval_Type_Conversion): Fix handling of enumeration to integer conversions. * exp_attr.adb (Expand_N_Attribute_Reference [Attribute_Enum_Rep]): Remove special casing for first-level renaming, best left to the general folding mechanism via Eval_Type_Conversion. 2020-06-08 Eric Botcazou * atree.adb (New_Copy): Do not clear Has_Dynamic_Range_Check. * checks.ads (Append_Range_Checks): Remove Flag_Node parameter.

(Set_Has_Dynamic_Range_Check): Likewise. * treepr.adb (Print_Node): Do not print Has_Dynamic_Range_Check. 2020-06-08 Steve Baird * sem_ch13.ads: Export new function All_Membership_Choices_Static. * sem_ch13.adb: Implement new function All_Membership_Choices_Static. This involves moving the functions Is_Static_Choice and All_Membership_Choices_Static, which were previously declared within the function Is_Predicate_Static, out to library level so that they can be called by the new function. The already-exisiting code in Is_Predicate_Static which became the body of All_Membership_Choices_Static is replaced with a call to the new function in order to avoid duplication. * exp_ch9.adb (Is_Pure_Barrier): Several changes needed to implement rules of AI12-0290 and RM D.7's definition of "pure-barrier-eligible". These changes include adding a call to the new function Sem_13.All_Membership_Choices_Static, as per the "see 4.9" in RM D.7(1.6/5). 2020-06-08 Richard Kenner * exp_unst.adb (Visit_Node): When visiting array attribute nodes, in addition to checking the type of Get_Referenced_Object of the prefix, also check the actual type of the prefix. 2020-06-08 Gary Dismukes * checks.adb (Apply_Predicate_Check): Refine test for being in a subprogram body to account for no Corresponding_Body case, avoiding blowups arising due to other changes here. * exp_ch4.adb (Expand_N_Qualified_Expression): Apply predicate checks, if any, after constraint checks are applied. * sem_eval.ads (Check_Expression_Against_Static_Predicate): Add Check_Failure_Is_Error formal for conditionalizing warning vs. error messages. * sem_eval.adb (Check_Expression_Against_Static_Predicate): Issue an error message rather than a warning when the new Check_Failure_Is_Error formal is True. In the nonstatic or Dynamic_Predicate case where the predicate is known to fail, emit the check to ensure that folded cases get checks applied. * sem_res.adb (Resolve_Qualified_Expression): Call Check_Expression_Against_Static_Predicate, passing True for Check_Failure_Is_Error, to ensure we reject static predicate violations. Remove code that was conditionally calling Apply_Predicate_Check, which is no longer needed, and that check procedure shouldn't be called from a resolution routine in any case. Also remove associated comment about preventing infinite recursion and consistency with Resolve_Type_Conversion, since that handling was already similarly removed from Resolve_Type_Convesion at some point. (Resolve_Type_Conversion): Add passing of True for Check_Failure_Is_Error parameter on call to Check_Expression_Against_Static_Predicate, to ensure that static conversion cases that violate a predicate are rejected as errors. 2020-06-08 Piotr Trojanek * snames.ads-tmpl (Name_SPARK): Restore after being deleted. 2020-06-08 Arnaud Charlet * exp_aggr.adb, exp_ch6.adb, par-ch11.adb, par-ch6.adb, par-ch7.adb, par-prag.adb, restrict.adb, restrict.ads, scans.ads, scng.adb, sem_aggr.adb, sem_attr.adb, sem_ch11.adb, sem_ch12.adb, sem_ch3.adb, sem_ch3.ads, sem_ch4.adb, sem_ch5.adb, sem_ch6.adb, sem_ch7.adb, sem_ch8.adb, sem_ch9.adb, sem_res.adb, sem_util.adb, sem_util.ads, snames.ads-tmpl, gnatbind.adb, libgnat/s-rident.ads, doc/gnat_rm/standard_and_implementation_defined_restrictions.rst: Remove processing of SPARK_05 restriction. * gnat_rm.texi: Regenerate. * opt.ads: Remove processing of old checksum which is now handled by gprbuild directly. 2020-06-08 Arnaud Charlet * sem_ch12.adb (Instantiate_Object): Relax rules related to null exclusions and generic objects. Handle all anonymous types consistently and not just E_Anonymous_Access_Type. * sem_ch8.adb (Analyze_Object_Renaming): Change wording so that it applies to both renamings and instantiations to avoid confusion. 2020-06-08 Arnaud Charlet * libgnat/a-textio.ads (File_Mode): Fix typo in comment. 2020-06-08 Eric Botcazou * sem_res.adb (Resolve_Indexed_Component): Do not give a warning for a nonatomic component of an atomic array which is subject to an address clause in Ada 2020 mode. (Resolve_Selected_Component): Likewise for an atomic record. 2020-06-08 Philippe Gil * doc/gnat_ugn/the_gnat_compilation_model.rst: in "Handling Files with Multiple Units" part documents gnatname use for unmodified files handling and gnatchop use for files refactoring. * gnat_ugn.texi: Regenerate. 2020-06-08 Arnaud Charlet * doc/gnat_rm/implementation_defined_attributes.rst: Enum_Rep/Enum_Val are standard Ada 202x attributes. * gnat_rm.texi: Regenerate. 2020-06-08 Javier Miranda * exp_aggr.adb (Safe_Component): Remove code that considers as unsafe components that are aggregates; such removal allows the frontend to proceed and evaluate if they are safe by means of invoking Safe_Aggregate. 2020-06-08 Piotr Trojanek * exp_spark.adb (Expand_SPARK_N_Attribute_Reference): Apply standard expansion to attributes First and Last. 2020-06-08 Piotr Trojanek * exp_attr.adb, exp_util.ads, exp_util.adb (Get_Index_Subtype): Move from the body of Exp_Attr to Exp_Util and expose from the spec. * exp_spark.adb (Expand_SPARK_N_Attribute_Reference): Replace duplicated code with a call to Get_Index_Subtype. 2020-06-08 Arnaud Charlet * sem_ch8.adb (Analyze_Object_Renaming): Simplify code by moving many special cases to Is_Object_Reference and removing others by only checking renamings coming from sources. * sem_util.adb (Is_Object_Reference): Update for AI12-0226 and add more regular handling of 'Priority. Remove special cases no longer needed now that we are only checking renamings coming from sources. 2020-06-08 Claire Dross * libgnat/a-cofove.adb (Insert_Space): The computation of Index generates a spurious compiler warning about a value not being in range for a statically dead branch. Silence it using pragma Warnings. 2020-06-08 Bob Duff * bindo-graphs.adb (function Add_Edge): Rename Add_Edge_With_Return to Add_Edge; we can tell it returns because it's a function, and overloading seems appropriate in this case. If Activates_Task=True, and we're not going to add a new edge because an existing Pred-->Succ edge already exists, then set Activates_Task to True on the preexisting edge. This ensures that the message: info: use pragma Restrictions (No_Entry_Calls_In_Elaboration_Code) appears when appropriate, no matter in what order the edges happened to be processed. (procedure Add_Edge): Remove redundant assertions. (Activates_Task): Other kinds of edges can have Activates_Task=True. For example, if we had a With_Edge and then an Invocation_Edge with Activates_Task=True, then the With_Edge has Activates_Task set to True. (Add_Edge_Kind_Check): New procedure to prevent other bugs of this nature. For example, if we were to sometimes call Add_Edge for a Spec_Before_Body_Edge followed by Add_Edge for a With_Edge, and sometimes in the other order, that would cause a similar bug to what we're fixing here. (Set_Is_Recorded_Edge): Val parameter is not used. Get rid of it. (Set_Activates_Task): New procedure to set the Activates_Task flag. * bindo-graphs.ads (Library_Graph_Edge_Kind): Reorder the enumeration literals to facilitate Add_Edge_Kind_Check. * ali.adb (Known_ALI_Lines): The comment about "still available" was wrong. Fix that by erasing the comment, and encoding the relevant information in real code. Take advantage of Ada's full coverage rules by removing "others =>". Also DRY. 2020-06-08 Ed Schonberg * par-ch12.adb (P_Formal_Derived_Type_Definition): Handle properly formal derived types that include aspect specifications, so that the "with" keyword appears twice in the formal type declaration. * sem_ch13.adb (Has_Generic_Parent): Return true if the type itself is a generic formal. 2020-06-08 Dmitriy Anisimkov * socket.c (__gnat_minus_500ms): Remove IsWindowsVersionOrGreater from condition. 2020-06-08 Claire Dross * libgnat/a-cfdlli.ads, libgnat/a-cfhama.ads, libgnat/a-cfhase.ads, libgnat/a-cforma.ads, libgnat/a-cforse.ads (Delete): Add Depends contract. 2020-06-08 Arnaud Charlet * snames.ads-tmpl (Name_Program_Error_Check, Name_Tasking_Check): New constants. * types.ads (Program_Error_Check, Tasking_Check): New constants.

When the insertion node is a declaration, only insert on the list if is present when the declaration involves discriminants, and only insert on the node when there is no list otherwise. 2020-06-05 Piotr Trojanek * sem_aggr.adb (Resolve_Record_Aggregate): Create the N_Aggregate node with its Expressions field set to No_List and not to an empty list. 2020-06-05 Dmitriy Anisimkov * libgnat/s-os_lib.adb (Is_Dirsep): Moved from Build_Path to package level to reuse. (Normalize_Pathname.Final_Value): Reduce 2 'if' statements to one. (Normalize_Pathname.Fill_Directory): New procedure instead of function Get_Directory. Remove slash to backslash conversion and drive letter uppercasing on Windows. 2020-06-05 Arnaud Charlet * sem.adb (Assert_Done): Relax check for main unit, as it was overzealous in the case of the main unit itself. 2020-06-05 Piotr Trojanek * exp_ch3.adb, sem_ch8.adb, sem_util.adb: Use Is_Incomplete_Type to make the code easier to read. 2020-06-05 Piotr Trojanek * einfo.adb: Minor reformatting. * sem_util.adb (Has_Full_Default_Initialization, Is_Partially_Initialized_Type, Caller_Known_Size_Record, Large_Max_Size_Mutable): Iterate with First_Component/Next_Component; rename Ent to Comp. 2020-06-05 Eric Botcazou * exp_aggr.adb (Aggr_Assignment_OK_For_Backend): Use Expr_Rep_Value instead of Expr_Value to obtain the equivalent integer value. * sem_eval.ads (Expr_Value): Document more supported cases. * sem_eval.adb (Expr_Rep_Value): Copy missing cases from Exp_Value. 2020-06-05 Bob Duff * rtsfind.adb, rtsfind.ads: Move subtypes of RTU_Id into package body, because they are not needed by clients. Change "Child_" to "Descendant", because grandchildren and great grandchildren are involved. Replace all the repetitive comments with a single concise one. Change the parent subtypes to be more consistent; use the most specific parent. 2020-06-05 Piotr Trojanek * rtsfind.ads, rtsfind.adb (Is_Text_IO_Special_Package): Moved from the GNATprove backend to the frontend. 2020-06-05 Yannick Moy * sem_util.ads: Add comment about function only used in CodePeer. 2020-06-05 Ed Schonberg * sem_ch9.adb, (Analyze_Task_Body): After analying the task body, indicate that all local variables have no delayed aspects. This prevents improper later calls to Check_Aspect_At_End_Of_Declarations, that would happen when the constructed task_procedure body (generated during expansion) is analyzed. The legality of aspect specifications that may appear on local declarations has already been established, and it is in general not possible to recheck them properly during expansion, when visibility may not be fully established. 2020-06-05 Piotr Trojanek * libgnat/a-cofuve.ads (First): Add Global contract. 2020-06-05 Arnaud Charlet * sem_prag.adb (Set_Convention_From_Pragma): Set the convention of anonymous access array components. 2020-06-05 Arnaud Charlet * libgnat/a-calfor.ads, libgnat/a-catizo.ads, libgnat/a-catizo.adb (Local_Time_Offset, Local_Image): New.
