(Might_Have_Tasks): Fix check of class-wide limited record types.

(Extra_Formals_OK): Subprogram moved from freeze.adb. * sem_eval.adb (Compile_Time_Known_Value): Improve predicate to avoid assertion failure; found working on this ticket; this change does not affect the behavior of the compiler because this subprogram has an exception handler that returns False when the assertion fails. * sem_util.adb (Needs_Result_Accessibility_Level): Do not return False for dispatching operations compiled with Ada_Version < 2012 since they they may be overridden by primitives compiled with Ada_Version >= Ada_2012. 2022-11-08 Bob Duff * warnsw.ads, warnsw.adb, fe.h, err_vars.ads, errout.ads: Move Warning_Doc_Switch from Err_Vars to Warnsw. Access Warn_On_Questionable_Layout on the C side via a function rather than a variable, because we plan to turn the variables into renamings, and you can't Export renamings. * erroutc.adb, switch-c.adb, errout.adb: Likewise. * gcc-interface/decl.cc: Use Get_Warn_On_Questionable_Layout instead of Warn_On_Questionable_Layout. * gcc-interface/Makefile.in (GNATMAKE_OBJS): Add warnsw.o, because it is indirectly imported via Errout. * gcc-interface/Make-lang.in (GNATBIND_OBJS): Likewise and remove restrict.o (not needed). 2022-11-08 Ronan Desplanques * doc/gnat_ugn/building_executable_programs_with_gnat.rst (-gnatwc): Fix flag documentation. * gnat_ugn.texi: Regenerate. 2022-11-08 Steve Baird * sem_ch3.adb (Analyze_Object_Declaration): Do not perform expansion actions if In_Spec_Expression is true. 2022-11-08 Eric Botcazou * sem_ch4.adb (Analyze_Qualified_Expression): Analyze the expression only after setting the type.

Move assertion thereof to more general place. (Expand_Composite_Equality): Pass in Outer_Type, for use in warnings. Rename Typ to be Comp_Type, to more clearly distinguish it from Outer_Type. Print warning when appropriate. * exp_ch4.ads: Minor comment fix. * errout.ads: There is no such pragma as Warning_As_Pragma -- Warning_As_Error must have been intended.

Also fixed the "is null;" procedure on the host side which are not Ada 95, replaced with a procedure raising an exception as it should never be called. Remove the unused function Device_Ada_Final_Link_Name. 2022-11-07 Steve Baird * opt.ads: Declare new string pointer variable, CUDA_Device_Library_Name. Modify comments for existing Boolean variable Enable_CUDA_Device_Expansion. * switch-b.adb: When "-d_c" switch is encountered, check that the next character is an "'='; use the remaining characters to initialize Opt.CUDA_Device_Library_Name. * bindgen.adb: Remove (for now) most support for host-side invocation of device-side finalization.

Declare the placeholder routine that is named in the CUDA_Execute pragma (and the CUDA_Register_Function call) as an exported null procedure, rather than as an imported procedure. It is not clear whether it is really necessary to specify the link-name for this should-never-be-called subprogram on the host side, but for now it shouldn't hurt to do so. 2022-11-07 Piotr Trojanek * exp_ch6.adb (Expand_Protected_Subprogram_Call): Examine scope tree and not the scope stack. 2022-11-07 Piotr Trojanek * mdll.ads (Build_Import_Library): Fix grammar in comment. * mdll.adb (Build_Import_Library): Directly execute code of a nested routine; rename No_Lib_Prefix to Strip_Lib_Prefix. 2022-11-07 Bob Duff * sem_warn.adb (Check_For_Warnings): Remove unnecessary exception handler. (Warn_On_Known_Condition): Suppress warning when we detect a True or False that has been turned into a more complex expression because True is represented as "nonzero". (Note that the complex expression will subsequently be constant-folded to a Boolean True or False). Also simplify to always print "condition is always ..." instead of special-casing object names. The special case was unhelpful, and indeed wrong when the expression is a literal. 2022-11-07 Piotr Trojanek * checks.adb (Safe_To_Capture_In_Parameter_Value): Remove. * sem_util.adb (Safe_To_Capture_Value): Stop search at the current body. 2022-11-07 Piotr Trojanek * sem_warn.adb (Warn_On_In_Out): Remove No_ prefix; flip return values between True and False; adapt caller. 2022-11-07 Piotr Trojanek * sem_ch13.adb (Add_Call): Just look at Instantiation_Depth. * sem_ch3.adb (Derive_Subprograms): Likewise. * sem_warn.adb (Check_References): Remove redundant filtering with Instantiation_Depth that follows filtering with Instantiation_Location. * sinput.adb (Instantiation_Depth): Reuse Instantiation_Location. 2022-11-07 Piotr Trojanek * sem_warn.adb (No_Warn_On_In_Out): For subprograms we can simply call Warnings_Off.

This complements the existing Enable_CUDA_Expansion variable, which is used to enable host-side CUDA expansion. The new variable enables device-side CUDA expansion. It is currently never set during compilation; it is only set via a binder switch. * switch-b.adb (scan_debug_switches): Add new use of the "-d_d" binder switch.

(Build_Subprogram_Contract_Wrapper): Created to do the majority of expansion for postconditions. It builds a local wrapper with the statements and declarations within a given subprogram. (Is_Prologue_Renaming): Moved out from Process_Preconditions to be used generally within the contracts package. (Build_Entry_Contract_Wrapper): Moved from exp_ch7. (Expand_Subprogram_Contract): Add new local variable Decls to store expanded declarations needed for evaluation of contracts.

(Analyze_Subprogram_Body_Helper): Remove global HSS variable due to the HSS of the body potentially changing during the expansion of contracts. In cases where it was used instead directly call Handled_Statement_Sequence. Modify expansion of subprogram bodies so that contracts (and their associated pragmas) get analyzed first. (Check_Missing_Return): Create local HSS variable instead of using a global one. (Move_Pragmas): Use new pragma table instead of an explicit list. * sem_elab.adb (Is_Postconditions_Proc): Deleted since the new scheme of expansion no longer divides postcondition checks to a separate subprogram and so cannot be easily identified (similar to pre-condition checks).

This is a correctness issue because the call to First_Entity can fail. 2022-09-12 Steve Baird * sem_ch9.adb (Satisfies_Lock_Free_Requirements): If Ceiling_Locking locking policy has been specified, then either return False (if Lock_Free was not explicitly specified) or generate a warning that ceiling locking will not be implemented for this protected unit (if Lock_Free was explicitly specified). Generate an error message (in addition to returning False) if an explicit Lock_Free aspect specification is rejected because atomic primitives are not supported on the given target. * doc/gnat_rm/implementation_defined_pragmas.rst: Clarify that the Lock_Free aspect for a protected unit takes precedence over the Ceiling_Locking locking policy in the case where both apply. * gnat_rm.texi: Regenerate. 2022-09-12 Eric Botcazou * exp_ch9.adb (Build_Protected_Spec): Tidy up and propagate the Comes_From_Source flag onto the new formal parameters. * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not check references for subprograms generated for protected subprograms. 2022-09-12 Gary Dismukes * sem_res.adb (Resolve_Equality_Op): Add handling for equality ops with user-defined literal operands. * sem_util.ads (Is_User_Defined_Literal): Update spec comment to indicate inclusion of named number cases. * sem_util.adb (Corresponding_Primitive_Op): Rather than following the chain of ancestor subprograms via Alias and Overridden_Operation links, we check for matching profiles between primitive subprograms of the descendant type and the ancestor subprogram (by calling a new nested function Profile_Matches_Ancestor). This prevents the compiler from hanging due to circular linkages via those fields that can occur between inherited and overriding subprograms (which might indicate a latent bug, but one that may be rather delicate to resolve). (Profile_Matches_Ancestor): New nested subprogram to compare the profile of a primitive subprogram with the profile of a candidate ancestor subprogram.

Note that we have to put "!!" before the "??", because Compile_Time_Constraint_Error detects warnings by comparing the last character of the message with '?' (which is bit dubious, but we're not changing that here). (Length_Mismatch_Info_Message): Use Unat for some things that can't be negative. Specify Decimal instead of Auto in calls to UI_Image. * sem_util.adb (Compile_Time_Constraint_Error): Minor. * uintp.adb (Image_Uint): It's always better to initialize objects on their declaration. 2022-09-12 Patrick Bernardi * libgnat/system-vxworks7-x86_64-kernel.ads: Set Support_Atomic_Primitives to false. * libgnat/system-vxworks7-x86_64-rtp-smp.ads: Ditto. 2022-09-12 Patrick Bernardi * libgnat/system-qnx-arm.ads: Set Support_Atomic_Primitives to false. * libgnat/system-vxworks7-aarch64.ads: Ditto. * libgnat/system-vxworks7-aarch64-rtp-smp.ads: Ditto. * libgnat/system-vxworks7-arm.ads: Ditto. * libgnat/system-vxworks7-arm-rtp-smp.ads: Ditto. * libgnat/system-vxworks7-x86-kernel.ads: Ditto. * libgnat/system-vxworks7-x86-rtp-smp.ads: Ditto. 2022-09-12 Bob Duff * par-tchk.adb, par-util.adb, prep.adb, prepcomp.adb, scng.adb: Use "in" instead of chains of "=" connected with "or else".

(Extra_Formals_Match_OK): New subprogram. * sem_eval.adb (Compile_Time_Known_Value): Improve predicate to avoid assertion failure; found working on this ticket; this change does not affect the behavior of the compiler because this subprogram has an exception handler that returns False when the assertion fails. * sem_util.adb (Needs_Result_Accessibility_Level): Do not return False for dispatching operations compiled with Ada_Version < 2012 since they they may be overridden by primitives compiled with Ada_Version >= Ada_2012. 2022-09-06 Eric Botcazou * gcc-interface/decl.cc (gnat_to_gnu_param): Set DECL_ARTIFICIAL. 2022-09-06 Eric Botcazou * gcc-interface/trans.cc (At_End_Proc_to_gnu): Use the End_Label of the child Handled_Statement_Sequence for body nodes. (set_end_locus_from_node): Minor tweaks. 2022-09-06 Eric Botcazou * gcc-interface/trans.cc (Full_View_Of_Private_Constant): New function returning the Full_View of a private constant, after looking through a chain of renamings, if any. (Identifier_to_gnu): Call it on the entity. Small cleanup. 2022-09-06 Eric Botcazou * gcc-interface/utils.cc (gnat_pushdecl): Preserve named TYPE_DECLs consistently for all kind of pointer types. 2022-09-06 Eric Botcazou * gcc-interface/trans.cc (gnat_to_gnu) : Report a violation of No_Dependence on System.GCC if the result type is larger than a word. : Likewise. : Likewise. : Likewise.

Return False in the case of a protected function whose result type requires use of the secondary stack. (Satisfies_Lock_Free_Requirements): This functions checks for certain constructs and returns False if one is found. In the case of a protected function, there is no need to check to see if the protected object is being modified. So it is ok to omit *some* checks in the case of a protected function. But other checks which are required (e.g., the test for a reference to a variable that is not part of the protected object) were being incorrectly omitted. This could result in accepting "Lock_Free => True" aspect specifications that should be rejected. * snames.adb-tmpl: Name_Lock_Free no longer requires special treatment in Get_Pragma_Id or Is_Pragma_Name (because it is no longer an attribute name). * snames.ads-tmpl: Move the declaration of Name_Lock_Free to reflect the fact that it is no longer the name of an attribute. Delete Attribute_Lock_Free from the Attribute_Id enumeration type. 2022-09-06 Steve Baird * libgnat/a-coorse.ads: Restore Aggregate aspect specification for type Set. 2022-09-06 Marc Poulhiès * exp_util.adb (Build_Allocate_Deallocate_Proc): Add Alignment_Param in the formal list for calls to SS_Allocate. 2022-09-06 Piotr Trojanek * inline.adb (Process_Formals): Preserve Has_Private_View flag while rewriting formal into actual parameters. 2022-09-06 Javier Miranda * debug.adb (Debug_Flag_Underscore_X): Switch added temporarily to allow disabling extra formal checks. * exp_attr.adb (Expand_N_Attribute_Reference [access types]): Add extra formals to the subprogram referenced in the prefix of 'Unchecked_Access, 'Unrestricted_Access or 'Access; required to check that its extra formals match the extra formals of the corresponding subprogram type. * exp_ch3.adb (Stream_Operation_OK): Declaration moved to the public part of the package.

In addition, a parameter has been added to disable assertion that requires its use with frozen entities. * freeze.adb (Check_Itype): Add extra formals to anonymous access subprogram itypes.

(Extra_Formals_Match_OK): New subprogram. * sem_eval.adb (Compile_Time_Known_Value): Improve predicate to avoid assertion failure; found working on this ticket; this change does not affect the behavior of the compiler because this subprogram has an exception handler that returns False when the assertion fails. * sem_util.adb (Needs_Result_Accessibility_Level): Do not return False for dispatching operations compiled with Ada_Version < 2012 since they they may be overridden by primitives compiled with Ada_Version >= Ada_2012. 2022-09-06 Arnaud Charlet * exp_ch4.adb (Expand_N_If_Expression): Disable optimization for LLVM. 2022-09-06 Javier Miranda * sem_prag.adb (Analyze_Pre_Post_Condition_In_Decl_Part): Improve check to report an error in non-legal class-wide conditions. 2022-09-06 Steve Baird * libgnat/a-strsup.adb, libgnat/a-stwisu.adb, libgnat/a-stzsup.adb (Super_Slice function and procedure): fix slice length computation. 2022-09-06 Steve Baird * doc/gnat_ugn/building_executable_programs_with_gnat.rst: Improve -gnatVa, -gnatVc, -gnatVd, -gnatVe, -gnatVf, -gnatVo, -gnatVp, -gnatVr, and -gnatVs switch descriptions. * gnat_ugn.texi: Regenerate. 2022-09-06 Justin Squirek * exp_unst.adb (Visit_Node): Add N_Block_Statement to the enclosing construct case since they can now have "At end" procedures. Also, recognize calls from "At end" procedures when recording subprograms. 2022-09-06 Piotr Trojanek * inline.adb (Replace_Formal): Fix name of the referenced routine. 2022-09-06 Piotr Trojanek * exp_attr.adb (Expand_N_Attribute_Reference [Attribute_Old]): Remove unnecessary local constant that was shadowing another constant with the same initial value. 2022-09-06 Julien Bortolussi * libgnat/a-cforse.ads (Replace): Fix the postcondition. 2022-09-06 Steve Baird * exp_attr.adb (Attribute_Valid): Ensure that PBtyp is initialized to a value for which Is_Scalar_Type is True. * checks.adb (Determine_Range): Call Implemention_Base_Type instead of Base_Type in order to ensure that result is suitable for passing to Enum_Pos_To_Rep. 2022-09-06 Bob Duff Eric Botcazou * gen_il-fields.ads (First_Real_Statement): Remove this field. * gen_il-gen-gen_nodes.adb: Remove the First_Real_Statement field. Add the At_End_Proc field to nodes that have both Declarations and HSS. * sinfo.ads (At_End_Proc): Document new semantics. (First_Real_Statement): Remove comment. * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Remove First_Real_Statement. * exp_ch7.adb (Build_Cleanup_Statements): Remove "Historical note"; it doesn't seem useful, and we have revision history. (Create_Finalizer): Insert the finalizer later, typically in the statement list, in some cases. (Build_Finalizer_Call): Attach the "at end" handler to the parent of the HSS node in most cases, so it applies to declarations. (Expand_Cleanup_Actions): Remove Wrap_HSS_In_Block and the call to it. Remove the code that moves declarations. Remove some redundant code. * exp_ch9.adb (Build_Protected_Entry): Copy the At_End_Proc. (Build_Protected_Subprogram_Body): Reverse the sense of Exc_Safe, to avoid double negatives. Remove "Historical note" as in exp_ch7.adb. (Build_Unprotected_Subprogram_Body): Copy the At_End_Proc from the protected version. (Expand_N_Conditional_Entry_Call): Use First (Statements(...)) instead of First_Real_Statement(...). (Expand_N_Task_Body): Put the Abort_Undefer call at the beginning of the declarations, rather than in the HSS. Use First (Statements(...)) instead of First_Real_Statement(...). Copy the At_End_Proc. * inline.adb (Has_Initialized_Type): Return False if the declaration does not come from source. * libgnarl/s-tpoben.ads (Lock_Entries, Lock_Entries_With_Status): Document when these things raise Program_Error. It's not clear that Lock_Entries_With_Status ought to be raising exceptions, but at least it's documented now. * sem.ads: Minor comment fixes. * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Use First (Statements(...)) instead of First_Real_Statement(...). (Analyze_Null_Procedure): Minor comment fix. * sem_util.adb (Might_Raise): Return True for N_Raise_Expression.

(Update_First_Real_Statement): Remove. * sem_util.ads: Remove First_Real_Statement from comment. * sinfo-utils.ads (First_Real_Statement): New function that always returns Empty. This should be removed once gnat-llvm and codepeer have been updated to not refer to First_Real_Statement. * sprint.adb (Sprint_At_End_Proc): Deal with printing At_End_Proc. * sem_prag.adb: Minor comment fixes. * gcc-interface/trans.cc (At_End_Proc_to_gnu): New function.

Setting this constant to True has two effects: 1- Representative value sets are not fully initialized - this is done to avoid capacity problems, as well as for performance. 2- In Check_Case_Pattern_Choices, the only legality check performed is a check that a "when others =>" choice is present. 2022-09-06 Piotr Trojanek * sem_ch13.adb (Analyze_Aspect_Relaxed_Initialization): Fix error template. 2022-09-06 Steve Baird * exp_attr.adb (Make_Range_Test): In determining which subtype's First and Last attributes are to be queried as part of a range test, call Validated_View in order to get a scalar (as opposed to private) subtype. (Attribute_Valid): In determining whether to perform a signed or unsigned comparison for a range test, call Validated_View in order to get a scalar (as opposed to private) type. Also correct a typo which, by itself, is the source of the problem reported for this ticket. 2022-09-06 Steve Baird * sem_ch4.adb (Analyze_Selected_Component): Define new Boolean-valued function, Constraint_Has_Unprefixed_Discriminant_Reference, which takes a subtype that is subject to a discriminant-dependent constraint and returns True if any of the constraint values are unprefixed discriminant names. Usually, the Etype of a selected component node is set to Etype of the component. However, in the case of an access-to-array component for which this predicate returns True, we instead use the base type of the Etype of the component. Normally such problematic discriminant references are addressed by calling Build_Actual_Subtype_Of_Component, but that doesn't work if Full_Analyze is False. 2022-09-06 Piotr Trojanek * Makefile.rtl (GNATRTL_NONTASKING_OBJS): Include System.Value_U_Spec and System.Value_I_Spec units. 2022-09-06 Eric Botcazou * libgnat/s-powflt.ads (Powfive): New constant array. * libgnat/s-powlfl.ads (Powfive): Likewise.

(Resolve_Iterable_Operation): Improve checks for illegal primitives in aspect Iterable, e.g. with wrong number of formal parameters. (Validate_Iterable_Aspect): Prevent crashes on syntactically illegal aspect expression. * sem_util.adb (Get_Cursor_Type): Fix style. * gnat_ugn.texi, gnat_rm.texi: Regenerate. 2022-09-06 Eric Botcazou * libgnat/s-valuer.ads (System.Value_R): Add Parts formal parameter as well as Data_Index, Scale_Array and Value_Array types.

(Value_Real): Likewise. 2022-09-05 Martin Liska * sigtramp-vxworks-target.h: Rename DBX_REGISTER_NUMBER to DEBUGGER_REGNO. 2022-09-05 Piotr Trojanek * exp_aggr.adb (Check_Bounds): Move code and comment related to check for null array aggregate from Resolve_Null_Array_Aggregate. * sem_aggr.ads (Is_Null_Aggregate): Move spec from unit body. * sem_aggr.adb (Resolve_Null_Array_Aggregate): Move check to expansion. 2022-09-05 Piotr Trojanek * sem_aggr.adb (Array_Aggr_Subtype): Bypass call to Collect_Aggr_Bound with dedicated code for null array aggregates. (Resolve_Array_Aggregate): Remove special handling of null array aggregates. (Resolve_Array_Aggregate): Create bounds, but let Array_Aggr_Subtype create itype entities. 2022-09-05 Piotr Trojanek * sem_aggr.adb (Resolve_Null_Array_Aggregate): Insert check as a Raise_Constraint_Error node and not an If_Statement. 2022-09-05 Piotr Trojanek * sem_aggr.adb (Resolve_Container_Aggregate): Style cleanup. (Resolve_Record_Aggregate): Remove redundant guard. 2022-09-05 Piotr Trojanek * exp_util.ads (Entry_Names_OK): Remove spec. * exp_util.adb (Entry_Names_OK): Remove body. 2022-09-05 Steve Baird * libgnat/a-coinve.adb, libgnat/a-convec.adb (Append): If the Append that takes an Element and a Count is called with Count = 1, then call the Append that does not take a Count parameter; otherwise call the code that handles the general case. Move the special case detection/handling code that was formerly in that version of Append into the version that does not take a Count parameter, so that now both versions get the performance benefit. 2022-09-05 Piotr Trojanek * sem_aggr.adb (Resolve_Null_Array_Aggregate): Create internal type for the aggregate as an itype. 2022-09-05 Piotr Trojanek * sem_util.ads (Itype_Has_Declaration): Remove spec. * sem_util.adb (Itype_Has_Declaration): Remove body. 2022-09-05 Steve Baird * exp_ch3.adb (Expand_N_Object_Declaration): In deciding whether to emit a DIC check, we were previously testing the Has_Init_Expression flag. Continue to test that flag as before, but add a test for the syntactic presence of an initial value in the object declaration. This new test would not supersede the old test in the case where an explicit initial value has been eliminated as part of some tree transformation. 2022-09-05 Piotr Trojanek * sem_ch13.adb (Validate_Unchecked_Conversions): Use Has_Warnings_Off. * sem_elab.adb (Check_Internal_Call_Continue): Likewise. 2022-09-05 Eric Botcazou * libgnat/s-valuer.adb (Scan_Decimal_Digits): Consistently avoid initializing local variables.

(Generate_Loop): Likewise for delta array aggregates. 2022-09-05 Piotr Trojanek * exp_aggr.adb (Two_Pass_Aggregate_Expansion): Expand iterated component association with an unanalyzed copy of iterated expression. The previous code worked only because the expanded loop used both an analyzed copy of the iterator_specification and an analyzed copy of the iterated expression. Now the iterated expression is reanalyzed in the context of the expanded loop. * par-ch4.adb (Build_Iterated_Component_Association): Don't set defining identifier when iterator specification is present. * sem_aggr.adb (Resolve_Iterated_Association): Pick index name from the iterator specification. * sem_elab.adb (Traverse_Potential_Scenario): Handle iterated element association just like iterated component association.

Remove useless freezing for first subtype.

(Name_Memory_Set): Likewise. 2022-07-13 Gary Dismukes * sem_ch13.adb (Check_And_Resolve_Storage_Model_Type_Argument): Call the System.Case_Util.To_Mixed procedure rather than the function, to avoid bootstrap problems. 2022-07-13 Gary Dismukes * aspects.ads (Aspect_Argument): Change the association for Aspect_Storage_Model_Type from Expression to Optional_Expression. * exp_util.ads (Find_Storage_Op): Update comment to indicate that Empty can be returned in the case where a storage-model operation is defaulted. * exp_util.adb (Find_Storage_Op): Allow the function to return Empty in Storage_Model_Type case rather than raising Program_Error, so that Procedure_To_Call fields in N_Allocator and N_Free_Statement nodes will be set to Empty in the defaulted native storage-model case. * sem_ch13.adb: Add with and use of System.Case_Util (and reformat context_clause). (Check_Aspect_At_Freeze_Point): Return with no action for a Storage_Model_Type aspect with no expression (fully-defaulted native memory-model case).

In cases where the search is done, but no association that matches Nam is found, return System.Address for the Name_Address_Type case, return System.Null_Address for the Name_Null_Address case, and return Empty for all other cases. 2022-07-13 Piotr Trojanek * sem_ch13.adb (Relocate_Expression): New routine with code that previously was only applied to Pre and Post aspects. (Analyze_Aspect_Specifications): Apply the above routine to other aspects, in particular to aspects Address, Attach_Handler, Predicate and Interrupt_Priority. 2022-07-13 Piotr Trojanek * inline.adb (Build_Body_To_Inline): Instead of manipulating the Full_Analysis flag, use the Inside_A_Generic flag (which is conveniently manipulated by Start_Generic/End_Generic, together with Expander_Active). * sem_attr.adb (Analyze_Attribute_Old_Result): Adapt comment and assertion to different flag that is set while building body-to-inline. 2022-07-13 Alexandre Oliva * doc/gnat_rm/security_hardening_features.rst: Clarify the need for choices after -fzero-call-used-regs and -fstrub. * gnat_rm.texi: Regenerate. 2022-07-13 Yannick Moy * sem_prag.adb (Analyze_Pragma): Recognize a generated subtype with Ghost pragma for generic instantiations. 2022-07-13 Yannick Moy * libgnat/s-aridou.adb (Lemma_Mult_Div, Lemma_Powers): New lemmas.

(Check_Untagged_Equality): Deal with subprogram bodies that are not the completion of a declaration and make sure that they are not flagged when they cause the freezing of the type themselves. Give a warning on the freezing point of the type in more cases. * sem_res.adb (Resolve_Equality_Op): Revert latest change. 2022-07-13 Yannick Moy * libgnat/s-arit32.adb (Scaled_Divide32): Add an assertion, move the call of Prove_Sign_R around. 2022-07-13 Marc Poulhiès * exp_ch4.adb (Expand_N_If_Expression): Test for compile time known bounds when handling slices. 2022-07-13 Eric Botcazou * exp_util.ads (Integer_Type_For): Mention Small_Integer_Type_For.

(P_Sequence_Of_Statements): Add Handled flag, to indicate whether to wrap the result in a block statement. * par-ch3.adb (P_Declarative_Item): Rename P_Declarative_Items to be P_Declarative_Item, because it really only parses a single declarative item, and to avoid conflict with the new P_Declarative_Items. Add In_Statements. We keep the old error-recovery mechanisms in place when In_Statements is False. When True, we don't want to complain about statements, because we are parsing a sequence of statements. (P_Identifier_Declarations): If In_Statements, and we see what looks like a statement, we no longer give an error. We return to P_Sequence_Of_Statements with Done = True, so it can parse the statement. * par-ch5.adb (P_Sequence_Of_Statements): Call P_Declarative_Items to parse declarative items that appear in the statement list. Remove error handling code that complained about such items. Check some errors conservatively. Wrap the result in a block statement when necessary. * par-ch11.adb (P_Handled_Sequence_Of_Statements): Pass Handled => True to P_Sequence_Of_Statements. * types.ads (No, Present): New functions for querying Source_Ptrs (equal, not equal No_Location). 2022-07-12 Piotr Trojanek * sem_prag.adb (Process_Restrictions_Or_Restriction_Warnings): Fix range of iteration. 2022-07-12 Piotr Trojanek * sem_prag.adb (Process_Restrictions_Or_Restriction_Warnings): Do not process expression of unknown restrictions. 2022-07-12 Vasiliy Fofanov * makeusg.adb, doc/gnat_ugn/building_executable_programs_with_gnat.rst: Move -P to the top of switches list and make it clear that gnatmake passes the ball to gprbuild if -P is set. * gnat_ugn.texi: Regenerate. 2022-07-12 Bob Duff * libgnat/g-socthi__vxworks.adb (C_Connect): Suppress new warning. 2022-07-12 Piotr Trojanek * sem_attr.adb (Set_Boolean_Result): Simplify using Boolean_Literals. 2022-07-12 Yannick Moy * errout.adb (Record_Compilation_Errors): Remove global variable.

If we remove unreachable code (including the return statement) from a function, add "raise Program_Error", so we won't warn about missing returns. Remove Original_Node in test for N_Raise_Statement; it's not needed. Remove test for CodePeer_Mode; if Operating_Mode = Generate_Code, then CodePeer_Mode can't be True. Misc cleanup. Do not reuse Nxt variable for unrelated purpose (the usage in the Kill_Dead_Code loop is entirely local to the loop). * sem_ch6.adb: Add check for Is_Transfer. Misc cleanup. * sem_prag.adb: Minor. * sem_res.adb: Minor. * sem_util.adb: Minor cleanup. (Is_Trivial_Boolean): Move to nonnested place, so it can be called from elsewhere.

So introduce a new function, Make_Expr_Copy, for use in these situations. * sem_res.adb (Preanalyze_And_Resolve): When analyzing certain expressions (e.g., a default parameter expression in a subprogram declaration) we want to suppress checks.

Without this patch, that bug would happen when we add the new Next procedure. For Step, make sure we pick the right one, by checking name and number of parameters. For Get_Element_Access, check that we're picking a function. That's not really necessary, because there is no procedure with that name, but it seems cleaner this way. * rtsfind.ads: Minor comment improvement.

We include all subprogram bodies, because it's harmless for procedures. We cannot easily avoid creating this block in ALL cases, because some transformations of (e.g.) task bodies end up moving some code such that the wrong exception handlers apply to that code. (Build_Finalizer_Call): Remove code for creating a new block. This was unreachable code, given that Wrap_HSS_In_Block has already done that, but with the above change to Wrap_HSS_In_Block, this code becomes reachable, and triggers essentially the same bug. * exp_ch7.ads: Adjust comment. 2022-05-30 Justin Squirek * par-ch6.adb (P_Formal_Part): Set Aspect_Specifications on all formals instead of just the last in a formal id list. * sem_ch6.adb (Analyze_Null_Procedure): Mark expanded null generic procedures as trivial in order to avoid spurious unreferenced warnings. 2022-05-30 Romain Beguet * libgnat/s-dwalin.adb: Add a subtype declaration to fix the ambiguity. 2022-05-30 Steve Baird * sem_ch13.adb (Is_Predicate_Static): Do not generate warnings about subexpressions of enclosing expressions.
