439 --------------------------------------------
440 -- Documentation for Compiler Debug Flags --
441 --------------------------------------------
443 -- da Generate messages tracking semantic analyzer progress. A message
444 -- is output showing each node as it gets analyzed, expanded,
445 -- resolved, or evaluated. This option is useful for finding out
446 -- exactly where a bomb during semantic analysis is occurring.
448 -- db In Exp_Dbug, certain type names are encoded to include debugging
449 -- information. This debug switch causes lines to be output showing
450 -- the encodings used.
452 -- dc List names of units as they are compiled. One line of output will
453 -- be generated at the start of compiling each unit (package or
456 -- dd Dynamic allocation of tables messages generated. Each time a
457 -- table is reallocated, a line is output indicating the expansion.
459 -- de List the entity table
461 -- df Full tree/source print (includes withed units). Normally the tree
462 -- output (dt) or recreated source output (dg,do,ds) includes only
463 -- the main unit. If df is set, then the output in either case
464 -- includes all compiled units (see also dg,do,ds,dt). Note that to
465 -- be effective, this switch must be used in combination with one or
466 -- more of dt, dg, do or ds.
468 -- dg Print the source recreated from the generated tree. In the case
469 -- where the tree has been rewritten this output includes only the
470 -- generated code, not the original code (see also df,do,ds,dz).
471 -- This flag differs from -gnatG in that the output also includes
472 -- non-source generated null statements, and freeze nodes, which
473 -- are normally omitted in -gnatG mode.
475 -- dh Generates a table at the end of a compilation showing how the hash
476 -- table chains built by the Namet package are loaded. This is useful
477 -- in ensuring that the hashing algorithm (in Namet.Hash) is working
478 -- effectively with typical sets of program identifiers.
480 -- di Generate messages for visibility linking/delinking
482 -- dj Suppress "junk null check" for access parameters. This flag permits
483 -- Ada programs to pass null parameters to access parameters, and to
484 -- explicitly check such access values against the null literal.
485 -- Neither of these is valid Ada, but both were allowed in versions of
486 -- GNAT before 3.10, so this switch can ease the transition process.
488 -- dk Immediate kill on abort. Normally on an abort (i.e. a call to
489 -- Comperr.Compiler_Abort), the GNATBUG message is not given if
490 -- there is a previous error. This debug switch bypasses this test
491 -- and gives the message unconditionally (useful for debugging).
493 -- dl Generate unit load trace messages. A line of traceback output is
494 -- generated each time a request is made to the library manager to
497 -- dm Prevent special frontend inlining in GNATprove mode. In some cases,
498 -- some subprogram calls are inlined in GNATprove mode in order to
499 -- facilitate formal verification. This debug switch prevents that
500 -- inlining to happen.
502 -- dn Generate messages for node/list allocation. Each time a node or
503 -- list header is allocated, a line of output is generated. Certain
504 -- other basic tree operations also cause a line of output to be
505 -- generated. This option is useful in seeing where the parser is
508 -- do Print the source recreated from the generated tree. In the case
509 -- where the tree has been rewritten, this output includes only the
510 -- original code, not the generated code (see also df,dg,ds,dz).
512 -- dp Generate messages for parser scope stack push/pops. A line of
513 -- output by the parser each time the parser scope stack is either
514 -- pushed or popped. Useful in debugging situations where the
515 -- parser scope stack ends up incorrectly synchronized
517 -- dq In layout version 1.38, 2002/01/12, a circuit was implemented
518 -- to give decent default alignment to short records that had no
519 -- specific alignment set. This debug option restores the previous
520 -- behavior of giving such records poor alignments, typically 1.
521 -- This may be useful in dealing with transition.
523 -- dr Generate parser resynchronization messages. Normally the parser
524 -- resynchronizes quietly. With this debug option, two messages
525 -- are generated, one when the parser starts a resynchronization
526 -- skip, and another when it resumes parsing. Useful in debugging
527 -- inadequate error recovery situations.
529 -- ds Print the source recreated from the generated tree. In the case
530 -- where the tree has been rewritten this output includes both the
531 -- generated code and the original code with the generated code
532 -- being enlosed in curly brackets (see also df,do,ds,dz)
534 -- dt Print full tree. The generated tree is output (see also df,dy)
536 -- du Uncheck categorization pragmas. This debug switch causes the
537 -- elaboration control pragmas (Pure, Preelaborate, etc.) and the
538 -- categorization pragmas (Shared_Passive, Remote_Types, etc.) to be
539 -- ignored, so that normal checks are not made (this is particularly
540 -- useful for adding temporary debugging code to units that have
541 -- pragmas that are inconsistent with the debugging code added).
543 -- dv Output trace of overload resolution. Outputs messages for
544 -- overload attempts that involve cascaded errors, or where
545 -- an interpretation is incompatible with the context.
547 -- dw Write semantic scope stack messages. Each time a scope is created
548 -- or removed, a message is output (see the Sem_Ch8.Push_Scope and
549 -- Sem_Ch8.Pop_Scope subprograms).
551 -- dx Force expansion on, even if no code being generated. Normally the
552 -- expander is inhibited if no code is generated. This switch forces
553 -- expansion to proceed normally even if the backend is not being
554 -- called. This is particularly useful for debugging purposes when
555 -- using the front-end only version of the compiler (which normally
556 -- would never do any expansion).
558 -- dy Print tree of package Standard. Normally the tree print out does
559 -- not include package Standard, even if the -df switch is set. This
560 -- switch forces output of the internal tree built for Standard.
562 -- dz Print source of package Standard. Normally the source print out
563 -- does not include package Standard, even if the -df switch is set.
564 -- This switch forces output of the source recreated from the internal
565 -- tree built for Standard. Note that this differs from -gnatS in
566 -- that it prints from the actual tree using the normal Sprint
567 -- circuitry for printing trees.
569 -- dA Forces output of representation information, including full
570 -- information for all internal type and object entities, as well
571 -- as all user defined type and object entities including private
572 -- and incomplete types. This debug switch also automatically sets
573 -- the equivalent of -gnatRm.
575 -- dB Output debug encodings for types and variants. See Exp_Dbug for
576 -- exact form of the generated output.
578 -- dC Output trace information showing the decisions made during
579 -- check suppression activity in unit Checks.
581 -- dD Delete new elaboration checks. This flag causes GNAT to return
582 -- to the 3.13a elaboration semantics, and to suppress the fixing
583 -- of two bugs. The first is in the context of inner routines in
584 -- dynamic elaboration mode, when the subprogram we are in was
585 -- called at elaboration time by a unit that was also compiled with
586 -- dynamic elaboration checks. In this case, if A calls B calls C,
587 -- and all are in different units, we need an elaboration check at
588 -- each call. These nested checks were only put in recently (see
589 -- version 1.80 of Sem_Elab) and we provide this debug flag to
590 -- revert to the previous behavior in case of regressions. The
591 -- other behavior reverted by this flag is the treatment of the
592 -- Elaborate_Body pragma in static elaboration mode. This used to
593 -- be treated as not needing elaboration checking, but in fact in
594 -- general Elaborate_All is still required because of nested calls.
596 -- dE Apply compile time elaboration checking for with relations between
597 -- predefined units. Normally no checks are made.
599 -- dG Generate all warnings. Normally Errout suppresses warnings on
600 -- units that are not part of the main extended source, and also
601 -- suppresses warnings on instantiations in the main extended
602 -- source that duplicate warnings already posted on the template.
603 -- This switch stops both kinds of deletion and causes Errout to
604 -- post all warnings sent to it.
606 -- dH Inhibit call to gigi. This is useful for testing front end data
607 -- layout, and may be useful in other debugging situations where
608 -- you do not want gigi to intefere with the testing.
610 -- dI Inhibit internal name numbering in gnatDG listing. Any sequence of
611 -- the form <uppercase-letter><digits><lowercase-letter> appearing in
612 -- a name is replaced by <uppercase-letter>...<lowercase-letter>. This
613 -- is used in the fixed bugs run to minimize system and version
614 -- dependency in filed -gnatD or -gnatG output.
616 -- dJ Prepend the name of the enclosing subprogram in compiler messages
617 -- (errors, warnings, style checks). This is useful in particular to
618 -- integrate compiler warnings in static analysis tools such as
621 -- dK Kill all error messages. This debug flag suppresses the output
622 -- of all error messages. It is used in regression tests where the
623 -- error messages are target dependent and irrelevant.
625 -- dL The compiler ignores calls in instances and invoke subprograms
626 -- which are external to the instance for both the static and dynamic
627 -- elaboration models.
629 -- dM Assume all variables have been modified, and ignore current value
630 -- indications. This debug flag disconnects the tracking of constant
631 -- values (see Exp_Ch2.Expand_Current_Value).
633 -- dN Do not generate file name information in exception messages
635 -- dO Output immediate error messages. This causes error messages to
636 -- be output as soon as they are generated (disconnecting several
637 -- circuits for improvement of messages, deletion of duplicate
638 -- messages etc). Useful to diagnose compiler bombs caused by
639 -- erroneous handling of error situations
641 -- dP Do not check for controlled objects in preelaborable packages.
642 -- RM 10.2.1(9) forbids the use of library level controlled objects
643 -- in preelaborable packages, but this restriction is a huge pain,
644 -- especially in the predefined library units.
646 -- dR Bypass the check for a proper version of s-rpc being present
647 -- to use the -gnatz? switch. This allows debugging of the use
648 -- of stubs generation without needing to have GLADE (or some
649 -- other PCS installed).
651 -- dS Omit conversion of fpt numbers to exact machine numbers in
652 -- non-static evaluation contexts (see Check_Non_Static_Context).
653 -- This is intended for testing out timing problems with this
654 -- conversion circuit.
656 -- dT Similar to dS, but omits the conversions only in the case where
657 -- the parent is not a constant declaration.
659 -- dU Enable garbage collection of unreachable entities. This enables
660 -- both the reachability analysis and changing the Is_Public and
661 -- Is_Eliminated flags.
663 -- dV Enable viewing of all symbols in debugger. Causes debug information
664 -- to be generated for all symbols, including internal symbols. This
665 -- is enabled by default for -gnatD, but this switch allows this to
666 -- be enabled without generating modified source files. Note that the
667 -- use of -gnatdV ensures in the dwarf/elf case that all symbols that
668 -- are present in the elf tables are also in the dwarf tables (which
669 -- seems to be required by some tools). Another effect of dV is to
670 -- generate full qualified names, including internal names generated
671 -- for blocks and loops.
673 -- dW Disable warnings when a possibly uninitialized scalar value is
674 -- passed to an IN OUT parameter of a procedure. This usage is a
675 -- quite improper bounded error [erroneous in Ada 83] situation,
676 -- and would normally generate a warning. However, to ease the
677 -- task of transitioning incorrect legacy code, we provide this
678 -- undocumented feature for suppressing these warnings.
680 -- dY Enable configurable run-time mode, just as though the System file
681 -- had Configurable_Run_Time_Mode set to True. This is useful in
682 -- testing high integrity mode.
684 -- dZ Generate listing showing the contents of the dispatch tables. Each
685 -- line has an internally generated number used for references between
686 -- tagged types and primitives. For each primitive the output has the
689 -- - Letter 'P' or letter 's': The former indicates that this
690 -- primitive will be located in a primary dispatch table. The
691 -- latter indicates that it will be located in a secondary
694 -- - Name of the primitive. In case of predefined Ada primitives
695 -- the text "(predefined)" is added before the name, and these
696 -- acronyms are used: SR (Stream_Read), SW (Stream_Write), SI
697 -- (Stream_Input), SO (Stream_Output), DA (Deep_Adjust), DF
698 -- (Deep_Finalize). In addition Oeq identifies the equality
699 -- operator, and "_assign" the assignment.
701 -- - If the primitive covers interface types, two extra fields
702 -- referencing other primitives are generated: "Alias" references
703 -- the primitive of the tagged type that covers an interface
704 -- primitive, and "AI_Alias" references the covered interface
707 -- - The expression "at #xx" indicates the slot of the dispatch
708 -- table occupied by such primitive in its corresponding primary
709 -- or secondary dispatch table.
711 -- - In case of abstract subprograms the text "is abstract" is
712 -- added at the end of the line.
714 -- d.a Force Target_Strict_Alignment to True, even on targets where it
715 -- would normally be false. Can be used for testing strict alignment
716 -- circuitry in the compiler.
718 -- d.b Dump back end types. During Create_Standard, the back end is
719 -- queried for all available types. This option shows them.
721 -- d.c Generate inline concatenation, instead of calling one of the
722 -- System.Concat_n.Str_Concat_n routines in cases where the latter
723 -- routines would normally be called.
725 -- d.d Disable atomic synchronization for all atomic variable references.
726 -- Pragma Enable_Atomic_Synchronization is ignored.
728 -- d.e Enable atomic synchronization for all atomic variable references.
729 -- Pragma Disable_Atomic_Synchronization is ignored, and also the
730 -- compiler switch -gnated is ignored.
732 -- d.f Suppress folding of static expressions. This of course results
733 -- in seriously non-conforming behavior, but is useful sometimes
734 -- when tracking down handling of complex expressions.
736 -- d.g Enables conversion of a raise statement into a goto when the
737 -- relevant handler is statically determinable. For now we only try
738 -- this if this debug flag is set. Later we will enable this more
739 -- generally by default.
741 -- d.h Minimize the creation of public internal symbols for concatenation
742 -- by enforcing a secondary stack-like handling of the final result.
743 -- The target of the concatenation is thus constrained in place and
744 -- initialized with the result instead of acting as its alias.
746 -- d.i Ignore all occurrences of pragma Warnings in the sources. This can
747 -- be used in particular to disable Warnings (Off) to check if any of
748 -- these statements are inappropriate.
750 -- d.k If an error message contains a reference to a location in an
751 -- internal unit, then suppress the line number in this reference.
753 -- d.j Generate listing of frontend inlined calls and inline calls passed
754 -- to the backend. This is useful to locate skipped calls that must be
755 -- inlined by the frontend.
757 -- d.l Use Ada 95 semantics for limited function returns. This may be
758 -- used to work around the incompatibility introduced by AI-318-2.
759 -- It is useful only in Ada 2005 and later.
761 -- d.m When -gnatl is used, the normal output includes full listings of
762 -- all files in the extended main source (body/spec/subunits). If this
763 -- debug switch is used, then the full listing is given only for the
764 -- main source (this corresponds to a previous behavior of -gnatl and
765 -- is used for running the ACATS tests).
767 -- d.n Print source file names as they are loaded. This is useful if the
768 -- compiler has a bug -- these are the files that need to be included
771 -- d.o Conservative elaboration order for indirect calls. This causes
772 -- P'Access to be treated as a call in more cases.
774 -- d.p In Ada 95 (or 83) mode, use original Ada 95 behavior for the
775 -- interpretation of component clauses crossing byte boundaries when
776 -- using the non-default bit order (i.e. ignore AI95-0133).
778 -- d.q If an array variable or constant is not modified in Ada code, and
779 -- is passed to an 'in' parameter of a foreign-convention subprogram,
780 -- and that subprogram modifies the array, the Ada compiler normally
781 -- assumes that the array is not modified. This option suppresses such
782 -- optimizations. This option should not be used; the correct solution
783 -- is to declare the parameter 'in out'.
785 -- d.r Do not reorder components in record types.
787 -- d.s The compiler no longer attempts to optimize the calls to secondary
788 -- stack management routines SS_Mark and SS_Release. As a result, each
789 -- transient block tasked with secondary stack management will fulfill
790 -- its role unconditionally.
792 -- d.s The compiler does not generate calls to secondary stack management
793 -- routines SS_Mark and SS_Release for a transient block when there is
794 -- an enclosing scoping construct which already manages the secondary
797 -- d.t The compiler has been modified (a fairly extensive modification)
798 -- to generate static dispatch tables for library level tagged types.
799 -- This debug switch disables this modification and reverts to the
800 -- previous dynamic construction of tables. It is there as a possible
801 -- work around if we run into trouble with the new implementation.
803 -- d.u Sets Modify_Tree_For_C mode in which tree is modified to make it
804 -- easier to generate code using a C compiler.
806 -- d.v This flag enforces the elaboration rules defined in the SPARK
807 -- Reference Manual, chapter 7.7, to all SPARK code within a unit. As
808 -- a result, constructs which violate the rules in chapter 7.7 are no
809 -- longer accepted, even if the implementation is able to statically
810 -- ensure that accepting these constructs does not introduce the
811 -- possibility of failing an elaboration check.
813 -- d.w This flag turns off the scanning of loops to detect possible
816 -- d.x No exception handlers in generated code. This causes exception
817 -- handlers to be eliminated from the generated code. They are still
818 -- fully compiled and analyzed, they just get eliminated from the
819 -- code generation step.
821 -- d.y Disable implicit pragma Elaborate_All on task bodies. When a task
822 -- body calls a procedure in the same package, and that procedure
823 -- calls a procedure in another package, the static elaboration
824 -- machinery adds an implicit Elaborate_All on the other package. This
825 -- switch disables the addition of the implicit pragma in such cases.
827 -- d.z Restore previous front-end support for Inline_Always. In default
828 -- mode, for targets that use the GCC back end, Inline_Always is
829 -- handled by the back end. Use of this switch restores the previous
830 -- handling of Inline_Always by the front end on such targets. For the
831 -- targets that do not use the GCC back end, this switch is ignored.
833 -- d.B Generate a bug box when we see an abort_statement, even though
834 -- there is no bug. Useful for testing Comperr.Compiler_Abort: write
835 -- some code containing an abort_statement, and compile it with
836 -- -gnatd.B. There is nothing special about abort_statements; it just
837 -- provides a way to control where the bug box is generated. See "when
838 -- N_Abort_Statement" in package body Expander.
840 -- d.C Generate call to System.Concat_n.Str_Concat_n routines in cases
841 -- where we would normally generate inline concatenation code.
843 -- d.D For compatibility with some Ada 95 compilers implementing only
844 -- one feature of Ada 2005 (overriding keyword), disable errors on use
845 -- of overriding keyword in Ada 95 mode.
847 -- d.E Turn selected errors into warnings. This debug switch causes a
848 -- specific set of error messages into warnings. Setting this switch
849 -- causes Opt.Error_To_Warning to be set to True. The intention is
850 -- that this be used for messages representing upwards incompatible
851 -- changes to Ada 2012 that cause previously correct programs to be
852 -- treated as illegal now. The following cases are affected:
854 -- Errors relating to overlapping subprogram parameters for cases
855 -- other than IN OUT parameters to functions.
857 -- Errors relating to the new rules about not defining equality
858 -- too late so that composition of equality can be assured.
860 -- Errors relating to overriding indicators on protected subprogram
861 -- bodies (not an Ada 2012 incompatibility, but might cause errors
862 -- for existing programs assuming they were legal because GNAT
863 -- formerly allowed them).
865 -- d.F Sets GNATprove_Mode to True. This allows debugging the frontend in
866 -- the special mode used by GNATprove.
868 -- d.G Previously the compiler ignored calls via generic formal parameters
869 -- when doing the analysis for the static elaboration model. This is
870 -- now fixed, but we provide this debug flag to revert to the previous
871 -- situation of ignoring such calls to aid in transition.
873 -- d.H Disable the support for 128-bit integer types on 64-bit platforms.
874 -- This makes it easier to mimic the behavior of the current compiler
875 -- on 32-bit platforms or of older compilers on 64-bit platforms.
877 -- d.I Do not ignore enum representation clauses in CodePeer mode.
878 -- The default of ignoring representation clauses for enumeration
879 -- types in CodePeer is good for the majority of Ada code, but in some
880 -- cases being able to change this default might be useful to remove
881 -- some false positives.
883 -- d.J Relaxed rules for pragma No_Return. A pragma No_Return is illegal
884 -- if it applies to a body. This switch disables the legality check
885 -- for that. If the procedure does in fact return normally, execution
886 -- is erroneous, and therefore unpredictable.
888 -- d.K Do not reject components in extensions overlapping with the parent
889 -- component. Such components can be specified by means of a component
890 -- clause but they cannot be fully supported by the GCC type system.
891 -- This switch nevertheless allows them for the sake of compatibility.
893 -- d.L Normally the front end generates special expansion for conditional
894 -- expressions of a limited type. This debug flag removes this special
895 -- case expansion, leaving it up to the back end to handle conditional
896 -- expressions correctly.
898 -- d.M Relaxed RM semantics. This flag sets Opt.Relaxed_RM_Semantics
899 -- See Opt.Relaxed_RM_Semantics for more details.
901 -- d.O Dump internal SCO tables. Before outputting the SCO information to
902 -- the ALI file, the internal SCO tables (SCO_Table/SCO_Unit_Table)
903 -- are dumped for debugging purposes.
905 -- d.P Previous non-optimized handling of length comparisons. Setting this
906 -- flag inhibits the effect of Optimize_Length_Comparison in Exp_Ch4.
907 -- This is there in case we find a situation where the optimization
908 -- malfunctions, to provide a work around.
910 -- d.Q Previous incomplete style checks for binary operators. Style checks
911 -- for token separation rules were incomplete and have been made
912 -- compliant with the documentation. For example, no warning was
913 -- issued for expressions such as 16-One or "A"&"B". Setting this flag
914 -- inhibits these new checks.
916 -- d.R As documented in lib-writ.ads, restrictions in the ali file can
917 -- have two forms, positional and named. The named notation is the
918 -- current preferred form, but the use of this debug switch will force
919 -- the use of the obsolescent positional form.
921 -- d.S Force Optimize_Alignment (Space) mode as the default
923 -- d.T Force Optimize_Alignment (Time) mode as the default
925 -- d.U Ignore indirect calls for static elaboration. The static
926 -- elaboration model is conservative, especially regarding indirect
927 -- calls. If you say Proc'Access, it will assume you might call
928 -- Proc. This can cause elaboration cycles at bind time. This flag
929 -- reverts to the behavior of earlier compilers, which ignored
932 -- d.V Do not verify the validity of SCIL files (CodePeer mode). When
933 -- generating SCIL files for CodePeer, by default we verify that the
934 -- SCIL is well formed before saving it on disk. This switch can be
935 -- used to disable this checking, either to improve speed or to shut
936 -- down a false positive detected during the verification.
938 -- d.W Print out debugging information for Walk_Library_Items, including
939 -- the order in which units are walked. This is primarily for use in
940 -- debugging CodePeer mode.
942 -- d.X A previous version of GNAT allowed indexing aspects to be redefined
943 -- on derived container types, while the default iterator was
944 -- inherited from the parent type. This nonstandard extension is
945 -- preserved temporarily for use by the modeling project under debug
948 -- d.Z Normally we always enable expansion in configurable run-time mode
949 -- to make sure we get error messages about unsupported features even
950 -- when compiling in -gnatc mode. But expansion is turned off in this
951 -- case if debug flag -gnatd.Z is used. This is to deal with the case
952 -- where we discover difficulties in this new processing.
954 -- d_a The compiler stops the examination of a task body once it reaches
955 -- an accept or select statement for the static elaboration model. The
956 -- behavior is similar to that of No_Entry_Calls_In_Elaboration_Code,
957 -- but does not penalize actual entry calls in elaboration code.
959 -- d_e The compiler ignores simple entry calls, asynchronous transfer of
960 -- control, conditional entry calls, timed entry calls, and requeue
961 -- statements in both the static and dynamic elaboration models.
963 -- d_f Issue info messages related to GNATprove usage to help users
964 -- understand analysis results. By default these are not issued as
965 -- beginners find them confusing. Set automatically by GNATprove when
966 -- switch --info is used.
968 -- d_h The compiler does not make use of (perfect) hash functions in the
969 -- implementation of the Value attribute for enumeration types.
971 -- d_i The compiler ignores calls and task activations when they target a
972 -- subprogram or task type defined in an external instance for both
973 -- the static and dynamic elaboration models.
975 -- d_j The compiler reads JSON files that would be generated by the same
976 -- compilation session if -gnatRjs was passed, in order to populate
977 -- the internal tables of the Repinfo unit from them.
979 -- d_p The compiler ignores calls to subprograms which verify the run-time
980 -- semantics of invariants and postconditions in both the static and
981 -- dynamic elaboration models.
983 -- d_s The compiler stops the examination of a task body once it reaches
984 -- a call to routine Ada.Synchronous_Task_Control.Suspend_Until_True
985 -- or Ada.Synchronous_Barriers.Wait_For_Release.
987 -- d_v Enable additional checks and debug printouts in Atree
989 -- d_x The compiler does not expand in line the Image attribute for user-
990 -- defined enumeration types and the standard boolean type.
992 -- d_z Enable the default Put_Image on tagged types that are not
995 -- d_A Do not generate ALI files by setting Opt.Disable_ALI_File.
997 -- d_B Warn on build-in-place function calls. This allows users to
998 -- inspect their code in case it triggers compiler bugs related
999 -- to build-in-place calls. See known-problem entries for details.
1001 -- d_F The compiler encodes the full path from an invocation construct to
1002 -- an external target, offering additional information to GNATBIND for
1003 -- purposes of error diagnostics.
1005 -- d_K (Reserved) Enable reporting a warning on known-problem issues of
1006 -- previous releases. No action performed in the wavefront.
1008 -- d_L Output trace information on elaboration checking. This debug switch
1009 -- causes output to be generated showing each call or instantiation as
1010 -- it is checked, and the progress of the recursive trace through
1011 -- elaboration calls at compile time.
1013 -- d_T The compiler outputs trace information to standard output whenever
1014 -- an invocation path is recorded.
1016 -- d_V Enable verification of the expanded code before calling the backend
1017 -- and generate error messages on each inconsistency found.
1019 -- d1 Error messages have node numbers where possible. Normally error
1020 -- messages have only source locations. This option is useful when
1021 -- debugging errors caused by expanded code, where the source location
1022 -- does not give enough information.
1024 -- d2 Suppress output of the error position flags for verbose form error
1025 -- messages. The messages are still interspersed in the listing, but
1026 -- without any error flags or extra blank lines. Also causes an extra
1027 -- <<< to be output at the right margin. This is intended to be the
1028 -- easiest format for checking conformance of ACATS B tests. This
1029 -- flag also suppresses the additional messages explaining why a
1030 -- non-static expression is non-static (see Sem_Eval.Why_Not_Static).
1031 -- This avoids having to worry about these messages in ACATS testing.
1032 -- Finally, this flag is also used for strict legality check, in
1033 -- particular it will generate an error instead a warning when
1034 -- encountering an unknown pragma.
1036 -- d3 Causes Comperr to dump the contents of the node for which an abort
1037 -- was detected (normally only the Node_Id of the node is output).
1039 -- d4 Inhibits automatic krunching of predefined library unit file names.
1040 -- Normally, as described in the spec of package Krunch, such files
1041 -- are automatically krunched to 8 characters, with special treatment
1042 -- of the prefixes Ada, System, and Interfaces. Setting this debug
1043 -- switch disables this special treatment.
1045 -- d5 Causes the tree read/write circuit to output detailed information
1046 -- tracking the data that is read and written element by element.
1048 -- d6 Normally access-to-unconstrained-array types are represented
1049 -- using fat (double) pointers. Using this debug flag causes them
1050 -- to default to thin. This can be used to test the performance
1051 -- implications of using thin pointers, and also to test that the
1052 -- compiler functions correctly with this choice.
1054 -- d7 Normally a -gnatl or -gnatv listing includes the time stamp of the
1055 -- source file and the time of the compilation. This debug flag can
1056 -- be used to suppress this output, and also suppresses the message
1057 -- with the version of the compiler. This is useful for regression
1058 -- tests which need to have consistent output.
1060 -- d8 This forces the packed stuff to generate code assuming the
1061 -- opposite endianness from the actual correct value. Useful in
1062 -- testing out code generation from the packed routines.
1064 -- d9 This allows lock free implementation for protected objects
1067 -- d.1 Sets Opt.Unnest_Subprogram_Mode to enable unnesting of subprograms.
1068 -- This special pass does not actually unnest things, but it ensures
1069 -- that a nested procedure does not contain any uplevel references.
1070 -- See spec of Exp_Unst for full details.
1072 -- d.2 Allow statements within declarative parts. This is not usually
1073 -- allowed, but in some debugging contexts (e.g. testing the circuit
1074 -- for unnesting of procedures), it is useful to allow this.
1076 -- d.3 Output debugging information from Exp_Unst, including the name of
1077 -- any unreachable subprograms that get deleted.
1079 -- d.4 By default in case of an error during C generation, the .c or .h
1080 -- file is deleted. This flag keeps the C file.
1082 -- d.5 By default a subprogram imported generates a subprogram profile.
1083 -- This debug flag disables this generation when generating C code,
1084 -- assuming a proper #include will be used instead.
1086 -- d.6 By default the C back-end avoids declaring types that are not
1087 -- referenced by the generated C code. This debug flag restores the
1088 -- output of all the types.
1090 -- d.7 Indicates (to gnat2scil) that CodePeer is being invoked as a
1091 -- prover by the SPARK tools and that therefore gnat2scil should
1092 -- avoid SCIL generation strategies which can introduce soundness
1093 -- issues (e.g., assuming that a low bound of an array parameter
1094 -- of an unconstrained subtype belongs to the index subtype).
