439 -- Documentation for Compiler Debug Flags --
440 --------------------------------------------
442 -- da Generate messages tracking semantic analyzer progress. A message
443 -- is output showing each node as it gets analyzed, expanded,
444 -- resolved, or evaluated. This option is useful for finding out
445 -- exactly where a bomb during semantic analysis is occurring.
447 -- db In Exp_Dbug, certain type names are encoded to include debugging
448 -- information. This debug switch causes lines to be output showing
449 -- the encodings used.
451 -- dc List names of units as they are compiled. One line of output will
452 -- be generated at the start of compiling each unit (package or
455 -- dd Dynamic allocation of tables messages generated. Each time a
456 -- table is reallocated, a line is output indicating the expansion.
458 -- de List the entity table
460 -- df Full tree/source print (includes withed units). Normally the tree
461 -- output (dt) or recreated source output (dg,do,ds) includes only
462 -- the main unit. If df is set, then the output in either case
463 -- includes all compiled units (see also dg,do,ds,dt). Note that to
464 -- be effective, this switch must be used in combination with one or
465 -- more of dt, dg, do or ds.
467 -- dg Print the source recreated from the generated tree. In the case
468 -- where the tree has been rewritten this output includes only the
469 -- generated code, not the original code (see also df,do,ds,dz).
470 -- This flag differs from -gnatG in that the output also includes
471 -- non-source generated null statements, and freeze nodes, which
472 -- are normally omitted in -gnatG mode.
474 -- dh Generates a table at the end of a compilation showing how the hash
475 -- table chains built by the Namet package are loaded. This is useful
476 -- in ensuring that the hashing algorithm (in Namet.Hash) is working
477 -- effectively with typical sets of program identifiers.
479 -- di Generate messages for visibility linking/delinking
481 -- dj Suppress "junk null check" for access parameters. This flag permits
482 -- Ada programs to pass null parameters to access parameters, and to
483 -- explicitly check such access values against the null literal.
484 -- Neither of these is valid Ada, but both were allowed in versions of
485 -- GNAT before 3.10, so this switch can ease the transition process.
487 -- dk Immediate kill on abort. Normally on an abort (i.e. a call to
488 -- Comperr.Compiler_Abort), the "GNAT BUG" message is not given if
489 -- there is a previous error. Instead, the message "compilation
490 -- abandoned due to previous error" is given. This debug switch
491 -- bypasses this test and gives the "GNAT BUG" message unconditionally
492 -- (useful for debugging). Use -gnatdO in addition to see the previous
495 -- dl Generate unit load trace messages. A line of traceback output is
496 -- generated each time a request is made to the library manager to
499 -- dm Prevent special frontend inlining in GNATprove mode. In some cases,
500 -- some subprogram calls are inlined in GNATprove mode in order to
501 -- facilitate formal verification. This debug switch prevents that
502 -- inlining to happen.
504 -- dn Generate messages for node/list allocation. Each time a node or
505 -- list header is allocated, a line of output is generated. Certain
506 -- other basic tree operations also cause a line of output to be
507 -- generated. This option is useful in seeing where the parser is
510 -- do Print the source recreated from the generated tree. In the case
511 -- where the tree has been rewritten, this output includes only the
512 -- original code, not the generated code (see also df,dg,ds,dz).
514 -- dp Generate messages for parser scope stack push/pops. A line of
515 -- output by the parser each time the parser scope stack is either
516 -- pushed or popped. Useful in debugging situations where the
517 -- parser scope stack ends up incorrectly synchronized
519 -- dq In layout version 1.38, 2002/01/12, a circuit was implemented
520 -- to give decent default alignment to short records that had no
521 -- specific alignment set. This debug option restores the previous
522 -- behavior of giving such records poor alignments, typically 1.
523 -- This may be useful in dealing with transition.
525 -- dr Generate parser resynchronization messages. Normally the parser
526 -- resynchronizes quietly. With this debug option, two messages
527 -- are generated, one when the parser starts a resynchronization
528 -- skip, and another when it resumes parsing. Useful in debugging
529 -- inadequate error recovery situations.
531 -- ds Print the source recreated from the generated tree. In the case
532 -- where the tree has been rewritten this output includes both the
533 -- generated code and the original code with the generated code
534 -- being enlosed in curly brackets (see also df,do,ds,dz)
536 -- dt Print full tree. The generated tree is output (see also df,dy)
538 -- du Uncheck categorization pragmas. This debug switch causes the
539 -- elaboration control pragmas (Pure, Preelaborate, etc.) and the
540 -- categorization pragmas (Shared_Passive, Remote_Types, etc.) to be
541 -- ignored, so that normal checks are not made (this is particularly
542 -- useful for adding temporary debugging code to units that have
543 -- pragmas that are inconsistent with the debugging code added).
545 -- dv Output trace of overload resolution. Outputs messages for
546 -- overload attempts that involve cascaded errors, or where
547 -- an interpretation is incompatible with the context.
549 -- dw Write semantic scope stack messages. Each time a scope is created
550 -- or removed, a message is output (see the Sem_Ch8.Push_Scope and
551 -- Sem_Ch8.Pop_Scope subprograms).
553 -- dx Force expansion on, even if no code being generated. Normally the
554 -- expander is inhibited if no code is generated. This switch forces
555 -- expansion to proceed normally even if the backend is not being
556 -- called. This is particularly useful for debugging purposes when
557 -- using the front-end only version of the compiler (which normally
558 -- would never do any expansion).
560 -- dy Print tree of package Standard. Normally the tree print out does
561 -- not include package Standard, even if the -df switch is set. This
562 -- switch forces output of the internal tree built for Standard.
564 -- dz Print source of package Standard. Normally the source print out
565 -- does not include package Standard, even if the -df switch is set.
566 -- This switch forces output of the source recreated from the internal
567 -- tree built for Standard. Note that this differs from -gnatS in
568 -- that it prints from the actual tree using the normal Sprint
569 -- circuitry for printing trees.
571 -- dA Forces output of representation information, including full
572 -- information for all internal type and object entities, as well
573 -- as all user defined type and object entities including private
574 -- and incomplete types. This debug switch also automatically sets
575 -- the equivalent of -gnatRm.
577 -- dB Output debug encodings for types and variants. See Exp_Dbug for
578 -- exact form of the generated output.
580 -- dC Output trace information showing the decisions made during
581 -- check suppression activity in unit Checks.
583 -- dD Delete new elaboration checks. This flag causes GNAT to return
584 -- to the 3.13a elaboration semantics, and to suppress the fixing
585 -- of two bugs. The first is in the context of inner routines in
586 -- dynamic elaboration mode, when the subprogram we are in was
587 -- called at elaboration time by a unit that was also compiled with
588 -- dynamic elaboration checks. In this case, if A calls B calls C,
589 -- and all are in different units, we need an elaboration check at
590 -- each call. These nested checks were only put in recently (see
591 -- version 1.80 of Sem_Elab) and we provide this debug flag to
592 -- revert to the previous behavior in case of regressions. The
593 -- other behavior reverted by this flag is the treatment of the
594 -- Elaborate_Body pragma in static elaboration mode. This used to
595 -- be treated as not needing elaboration checking, but in fact in
596 -- general Elaborate_All is still required because of nested calls.
598 -- dE Apply compile time elaboration checking for with relations between
599 -- predefined units. Normally no checks are made.
601 -- dG Generate all warnings. Normally Errout suppresses warnings on
602 -- units that are not part of the main extended source, and also
603 -- suppresses warnings on instantiations in the main extended
604 -- source that duplicate warnings already posted on the template.
605 -- This switch stops both kinds of deletion and causes Errout to
606 -- post all warnings sent to it.
608 -- dH Inhibit call to gigi. This is useful for testing front end data
609 -- layout, and may be useful in other debugging situations where
610 -- you do not want gigi to intefere with the testing.
612 -- dI Inhibit internal name numbering in gnatDG listing. Any sequence of
613 -- the form <uppercase-letter><digits><lowercase-letter> appearing in
614 -- a name is replaced by <uppercase-letter>...<lowercase-letter>. This
615 -- is used in the fixed bugs run to minimize system and version
616 -- dependency in filed -gnatD or -gnatG output.
618 -- dJ Prepend the name of the enclosing subprogram in compiler messages
619 -- (errors, warnings, style checks). This is useful in particular to
620 -- integrate compiler warnings in static analysis tools such as
623 -- dK Kill all error messages. This debug flag suppresses the output
624 -- of all error messages. It is used in regression tests where the
625 -- error messages are target dependent and irrelevant.
627 -- dL The compiler ignores calls in instances and invoke subprograms
628 -- which are external to the instance for both the static and dynamic
629 -- elaboration models.
631 -- dM Assume all variables have been modified, and ignore current value
632 -- indications. This debug flag disconnects the tracking of constant
633 -- values (see Exp_Ch2.Expand_Current_Value).
635 -- dN Do not generate file name information in exception messages
637 -- dO Output immediate error messages. This causes error messages to
638 -- be output as soon as they are generated (disconnecting several
639 -- circuits for improvement of messages, deletion of duplicate
640 -- messages etc). Useful to diagnose compiler bombs caused by
641 -- erroneous handling of error situations
643 -- dP Do not check for controlled objects in preelaborable packages.
644 -- RM 10.2.1(9) forbids the use of library level controlled objects
645 -- in preelaborable packages, but this restriction is a huge pain,
646 -- especially in the predefined library units.
648 -- dR Bypass the check for a proper version of s-rpc being present
649 -- to use the -gnatz? switch. This allows debugging of the use
650 -- of stubs generation without needing to have GLADE (or some
651 -- other PCS installed).
653 -- dS Omit conversion of fpt numbers to exact machine numbers in
654 -- non-static evaluation contexts (see Check_Non_Static_Context).
655 -- This is intended for testing out timing problems with this
656 -- conversion circuit.
658 -- dT Similar to dS, but omits the conversions only in the case where
659 -- the parent is not a constant declaration.
661 -- dU Enable garbage collection of unreachable entities. This enables
662 -- both the reachability analysis and changing the Is_Public and
663 -- Is_Eliminated flags.
665 -- dV Enable viewing of all symbols in debugger. Causes debug information
666 -- to be generated for all symbols, including internal symbols. This
667 -- is enabled by default for -gnatD, but this switch allows this to
668 -- be enabled without generating modified source files. Note that the
669 -- use of -gnatdV ensures in the dwarf/elf case that all symbols that
670 -- are present in the elf tables are also in the dwarf tables (which
671 -- seems to be required by some tools). Another effect of dV is to
672 -- generate full qualified names, including internal names generated
673 -- for blocks and loops.
675 -- dW Disable warnings when a possibly uninitialized scalar value is
676 -- passed to an IN OUT parameter of a procedure. This usage is a
677 -- quite improper bounded error [erroneous in Ada 83] situation,
678 -- and would normally generate a warning. However, to ease the
679 -- task of transitioning incorrect legacy code, we provide this
680 -- undocumented feature for suppressing these warnings.
682 -- dY Enable configurable run-time mode, just as though the System file
683 -- had Configurable_Run_Time_Mode set to True. This is useful in
684 -- testing high integrity mode.
686 -- dZ Generate listing showing the contents of the dispatch tables. Each
687 -- line has an internally generated number used for references between
688 -- tagged types and primitives. For each primitive the output has the
691 -- - Letter 'P' or letter 's': The former indicates that this
692 -- primitive will be located in a primary dispatch table. The
693 -- latter indicates that it will be located in a secondary
696 -- - Name of the primitive. In case of predefined Ada primitives
697 -- the text "(predefined)" is added before the name, and these
698 -- acronyms are used: SR (Stream_Read), SW (Stream_Write), SI
699 -- (Stream_Input), SO (Stream_Output), DA (Deep_Adjust), DF
700 -- (Deep_Finalize). In addition Oeq identifies the equality
701 -- operator, and "_assign" the assignment.
703 -- - If the primitive covers interface types, two extra fields
704 -- referencing other primitives are generated: "Alias" references
705 -- the primitive of the tagged type that covers an interface
706 -- primitive, and "AI_Alias" references the covered interface
709 -- - The expression "at #xx" indicates the slot of the dispatch
710 -- table occupied by such primitive in its corresponding primary
711 -- or secondary dispatch table.
713 -- - In case of abstract subprograms the text "is abstract" is
714 -- added at the end of the line.
716 -- d.a Force Target_Strict_Alignment to True, even on targets where it
717 -- would normally be false. Can be used for testing strict alignment
718 -- circuitry in the compiler.
720 -- d.b Dump back end types. During Create_Standard, the back end is
721 -- queried for all available types. This option shows them.
723 -- d.c Generate inline concatenation, instead of calling one of the
724 -- System.Concat_n.Str_Concat_n routines in cases where the latter
725 -- routines would normally be called.
727 -- d.d Disable atomic synchronization for all atomic variable references.
728 -- Pragma Enable_Atomic_Synchronization is ignored.
730 -- d.e Enable atomic synchronization for all atomic variable references.
731 -- Pragma Disable_Atomic_Synchronization is ignored, and also the
732 -- compiler switch -gnated is ignored.
734 -- d.f Suppress folding of static expressions. This of course results
735 -- in seriously non-conforming behavior, but is useful sometimes
736 -- when tracking down handling of complex expressions.
738 -- d.g Enables conversion of a raise statement into a goto when the
739 -- relevant handler is statically determinable. For now we only try
740 -- this if this debug flag is set. Later we will enable this more
741 -- generally by default.
743 -- d.h Minimize the creation of public internal symbols for concatenation
744 -- by enforcing a secondary stack-like handling of the final result.
745 -- The target of the concatenation is thus constrained in place and
746 -- initialized with the result instead of acting as its alias.
748 -- d.i Ignore all occurrences of pragma Warnings in the sources. This can
749 -- be used in particular to disable Warnings (Off) to check if any of
750 -- these statements are inappropriate.
752 -- d.k If an error message contains a reference to a location in an
753 -- internal unit, then suppress the line number in this reference.
755 -- d.j Generate listing of frontend inlined calls and inline calls passed
756 -- to the backend. This is useful to locate skipped calls that must be
757 -- inlined by the frontend.
759 -- d.l Use Ada 95 semantics for limited function returns. This may be
760 -- used to work around the incompatibility introduced by AI-318-2.
761 -- It is useful only in Ada 2005 and later.
763 -- d.m When -gnatl is used, the normal output includes full listings of
764 -- all files in the extended main source (body/spec/subunits). If this
765 -- debug switch is used, then the full listing is given only for the
766 -- main source (this corresponds to a previous behavior of -gnatl and
767 -- is used for running the ACATS tests).
769 -- d.n Print source file names as they are loaded. This is useful if the
770 -- compiler has a bug -- these are the files that need to be included
773 -- d.o Conservative elaboration order for indirect calls. This causes
774 -- P'Access to be treated as a call in more cases.
776 -- d.p In Ada 95 (or 83) mode, use original Ada 95 behavior for the
777 -- interpretation of component clauses crossing byte boundaries when
778 -- using the non-default bit order (i.e. ignore AI95-0133).
780 -- d.q If an array variable or constant is not modified in Ada code, and
781 -- is passed to an 'in' parameter of a foreign-convention subprogram,
782 -- and that subprogram modifies the array, the Ada compiler normally
783 -- assumes that the array is not modified. This option suppresses such
784 -- optimizations. This option should not be used; the correct solution
785 -- is to declare the parameter 'in out'.
787 -- d.r Do not reorder components in record types.
789 -- d.s The compiler no longer attempts to optimize the calls to secondary
790 -- stack management routines SS_Mark and SS_Release. As a result, each
791 -- transient block tasked with secondary stack management will fulfill
792 -- its role unconditionally.
794 -- d.s The compiler does not generate calls to secondary stack management
795 -- routines SS_Mark and SS_Release for a transient block when there is
796 -- an enclosing scoping construct which already manages the secondary
799 -- d.t The compiler has been modified (a fairly extensive modification)
800 -- to generate static dispatch tables for library level tagged types.
801 -- This debug switch disables this modification and reverts to the
802 -- previous dynamic construction of tables. It is there as a possible
803 -- work around if we run into trouble with the new implementation.
805 -- d.u Sets Modify_Tree_For_C mode in which tree is modified to make it
806 -- easier to generate code using a C compiler.
808 -- d.v This flag enforces the elaboration rules defined in the SPARK
809 -- Reference Manual, chapter 7.7, to all SPARK code within a unit. As
810 -- a result, constructs which violate the rules in chapter 7.7 are no
811 -- longer accepted, even if the implementation is able to statically
812 -- ensure that accepting these constructs does not introduce the
813 -- possibility of failing an elaboration check.
815 -- d.w This flag turns off the scanning of loops to detect possible
818 -- d.x No exception handlers in generated code. This causes exception
819 -- handlers to be eliminated from the generated code. They are still
820 -- fully compiled and analyzed, they just get eliminated from the
821 -- code generation step.
823 -- d.y Disable implicit pragma Elaborate_All on task bodies. When a task
824 -- body calls a procedure in the same package, and that procedure
825 -- calls a procedure in another package, the static elaboration
826 -- machinery adds an implicit Elaborate_All on the other package. This
827 -- switch disables the addition of the implicit pragma in such cases.
829 -- d.z Restore previous front-end support for Inline_Always. In default
830 -- mode, for targets that use the GCC back end, Inline_Always is
831 -- handled by the back end. Use of this switch restores the previous
832 -- handling of Inline_Always by the front end on such targets. For the
833 -- targets that do not use the GCC back end, this switch is ignored.
835 -- d.A Enable statistics printing in Atree. First set Statistics_Enabled
836 -- in gen_il-gen.adb to True, then rebuild, then run the compiler
837 -- with -gnatd.A. You might want to apply "sort -nr" to parts of the
840 -- d.B Generate a "GNAT BUG" message when we see an abort_statement, even
841 -- though there is no bug. Useful for testing Comperr.Compiler_Abort:
842 -- write some code containing an abort_statement, and compile it with
843 -- -gnatd.B. There is nothing special about abort_statements; it just
844 -- provides a way to control where the bug box is generated. See the
845 -- "when N_Abort_Statement" in package body Expander.
847 -- d.C Generate call to System.Concat_n.Str_Concat_n routines in cases
848 -- where we would normally generate inline concatenation code.
850 -- d.D For compatibility with some Ada 95 compilers implementing only
851 -- one feature of Ada 2005 (overriding keyword), disable errors on use
852 -- of overriding keyword in Ada 95 mode.
854 -- d.E Turn selected errors into warnings. This debug switch causes a
855 -- specific set of error messages into warnings. Setting this switch
856 -- causes Opt.Error_To_Warning to be set to True. The intention is
857 -- that this be used for messages representing upwards incompatible
858 -- changes to Ada 2012 that cause previously correct programs to be
859 -- treated as illegal now. The following cases are affected:
861 -- Errors relating to overlapping subprogram parameters for cases
862 -- other than IN OUT parameters to functions.
864 -- Errors relating to the new rules about not defining equality
865 -- too late so that composition of equality can be assured.
867 -- Errors relating to overriding indicators on protected subprogram
868 -- bodies (not an Ada 2012 incompatibility, but might cause errors
869 -- for existing programs assuming they were legal because GNAT
870 -- formerly allowed them).
872 -- d.F Sets GNATprove_Mode to True. This allows debugging the frontend in
873 -- the special mode used by GNATprove.
875 -- d.G Previously the compiler ignored calls via generic formal parameters
876 -- when doing the analysis for the static elaboration model. This is
877 -- now fixed, but we provide this debug flag to revert to the previous
878 -- situation of ignoring such calls to aid in transition.
880 -- d.H Disable the support for 128-bit integer types on 64-bit platforms.
881 -- This makes it easier to mimic the behavior of the current compiler
882 -- on 32-bit platforms or of older compilers on 64-bit platforms.
884 -- d.I Do not ignore enum representation clauses in CodePeer mode.
885 -- The default of ignoring representation clauses for enumeration
886 -- types in CodePeer is good for the majority of Ada code, but in some
887 -- cases being able to change this default might be useful to remove
888 -- some false positives.
890 -- d.J Relaxed rules for pragma No_Return. A pragma No_Return is illegal
891 -- if it applies to a body. This switch disables the legality check
892 -- for that. If the procedure does in fact return normally, execution
893 -- is erroneous, and therefore unpredictable.
895 -- d.K Do not reject components in extensions overlapping with the parent
896 -- component. Such components can be specified by means of a component
897 -- clause but they cannot be fully supported by the GCC type system.
898 -- This switch nevertheless allows them for the sake of compatibility.
900 -- d.M Relaxed RM semantics. This flag sets Opt.Relaxed_RM_Semantics
901 -- See Opt.Relaxed_RM_Semantics for more details.
903 -- d.N Use rounding instead of truncation when dynamically converting from
904 -- a floating-point type to an ordinary fixed-point type, for the sake
905 -- of compatibility with earlier versions of the compiler.
907 -- d.O Dump internal SCO tables. Before outputting the SCO information to
908 -- the ALI file, the internal SCO tables (SCO_Table/SCO_Unit_Table)
909 -- are dumped for debugging purposes.
911 -- d.P Previous non-optimized handling of length comparisons. Setting this
912 -- flag inhibits the effect of Optimize_Length_Comparison in Exp_Ch4.
913 -- This is there in case we find a situation where the optimization
914 -- malfunctions, to provide a work around.
916 -- d.Q Previous incomplete style checks for binary operators. Style checks
917 -- for token separation rules were incomplete and have been made
918 -- compliant with the documentation. For example, no warning was
919 -- issued for expressions such as 16-One or "A"&"B". Setting this flag
920 -- inhibits these new checks.
922 -- d.R As documented in lib-writ.ads, restrictions in the ali file can
923 -- have two forms, positional and named. The named notation is the
924 -- current preferred form, but the use of this debug switch will force
925 -- the use of the obsolescent positional form.
927 -- d.S Force Optimize_Alignment (Space) mode as the default
929 -- d.T Force Optimize_Alignment (Time) mode as the default
931 -- d.U Ignore indirect calls for static elaboration. The static
932 -- elaboration model is conservative, especially regarding indirect
933 -- calls. If you say Proc'Access, it will assume you might call
934 -- Proc. This can cause elaboration cycles at bind time. This flag
935 -- reverts to the behavior of earlier compilers, which ignored
938 -- d.V Do not verify the validity of SCIL files (CodePeer mode). When
939 -- generating SCIL files for CodePeer, by default we verify that the
940 -- SCIL is well formed before saving it on disk. This switch can be
941 -- used to disable this checking, either to improve speed or to shut
942 -- down a false positive detected during the verification.
944 -- d.W Print out debugging information for Walk_Library_Items, including
945 -- the order in which units are walked. This is primarily for use in
946 -- debugging CodePeer mode.
948 -- d.X A previous version of GNAT allowed indexing aspects to be redefined
949 -- on derived container types, while the default iterator was
950 -- inherited from the parent type. This nonstandard extension is
951 -- preserved temporarily for use by the modeling project under debug
954 -- d.Z Normally we always enable expansion in configurable run-time mode
955 -- to make sure we get error messages about unsupported features even
956 -- when compiling in -gnatc mode. But expansion is turned off in this
957 -- case if debug flag -gnatd.Z is used. This is to deal with the case
958 -- where we discover difficulties in this new processing.
960 -- d_a The compiler stops the examination of a task body once it reaches
961 -- an accept or select statement for the static elaboration model. The
962 -- behavior is similar to that of No_Entry_Calls_In_Elaboration_Code,
963 -- but does not penalize actual entry calls in elaboration code.
965 -- d_b When the restriction No_Dynamic_Accessibility_Checks is enabled,
966 -- use the simple "designated type" accessibility model, instead of
967 -- using the implicit level of the anonymous access type declaration.
969 -- d_e The compiler ignores simple entry calls, asynchronous transfer of
970 -- control, conditional entry calls, timed entry calls, and requeue
971 -- statements in both the static and dynamic elaboration models.
973 -- d_f Issue info messages related to GNATprove usage to help users
974 -- understand analysis results. By default these are not issued as
975 -- beginners find them confusing. Set automatically by GNATprove when
976 -- switch --info is used.
978 -- d_g Disable large static aggregates. The maximum size for a static
979 -- aggregate will be fairly modest, which is useful if the compiler
980 -- is using too much memory and time at compile time.
982 -- d_h The compiler does not make use of (perfect) hash functions in the
983 -- implementation of the Value attribute for enumeration types.
985 -- d_i The compiler ignores calls and task activations when they target a
986 -- subprogram or task type defined in an external instance for both
987 -- the static and dynamic elaboration models.
989 -- d_j The compiler reads JSON files that would be generated by the same
990 -- compilation session if -gnatRjs was passed, in order to populate
991 -- the internal tables of the Repinfo unit from them.
993 -- d_p The compiler ignores calls to subprograms which verify the run-time
994 -- semantics of invariants and postconditions in both the static and
995 -- dynamic elaboration models.
997 -- d_r The compiler does not make use of the return slot in the expansion
998 -- of functions returning a by-reference type. If this use is required
999 -- for these functions to return on the primary stack, then they are
1000 -- changed to return on the secondary stack instead.
1002 -- d_s The compiler stops the examination of a task body once it reaches
1003 -- a call to routine Ada.Synchronous_Task_Control.Suspend_Until_True
1004 -- or Ada.Synchronous_Barriers.Wait_For_Release.
1006 -- d_t In the LLVM-based CCG, do an additional dump of the LLVM IR
1007 -- after the pass that does transformations to the IR into a
1008 -- filename ending with .trans.ll.
1010 -- d_u In the LLVM-based CCG, dump flows, both when originally created
1011 -- and after transformations.
1013 -- d_v Enable additional checks and debug printouts in Atree
1015 -- d_x The compiler does not expand in line the Image attribute for user-
1016 -- defined enumeration types and the standard boolean type.
1018 -- d_A Do not generate ALI files by setting Opt.Disable_ALI_File.
1020 -- d_B Warn on build-in-place function calls. This allows users to
1021 -- inspect their code in case it triggers compiler bugs related
1022 -- to build-in-place calls. See known-problem entries for details.
1024 -- d_F The compiler encodes the full path from an invocation construct to
1025 -- an external target, offering additional information to GNATBIND for
1026 -- purposes of error diagnostics.
1028 -- d_K (Reserved) Enable reporting a warning on known-problem issues of
1029 -- previous releases. No action performed in the wavefront.
1031 -- d_L Output trace information on elaboration checking. This debug switch
1032 -- causes output to be generated showing each call or instantiation as
1033 -- it is checked, and the progress of the recursive trace through
1034 -- elaboration calls at compile time.
1036 -- d_R In the LLVM backend, output the internal representation of
1039 -- d_T The compiler outputs trace information to standard output whenever
1040 -- an invocation path is recorded.
1042 -- d_U Disable prepending 'error:' to error messages. This used to be the
1043 -- default and can be seen as the opposite of -gnatU.
1045 -- d_V Enable verification of the expanded code before calling the backend
1046 -- and generate error messages on each inconsistency found.
1048 -- d_X Disable assertions to check matching of extra formals; switch added
1049 -- temporarily to disable these checks until this work is complete if
1050 -- they cause unexpected assertion failures.
1052 -- d1 Error messages have node numbers where possible. Normally error
1053 -- messages have only source locations. This option is useful when
1054 -- debugging errors caused by expanded code, where the source location
1055 -- does not give enough information.
1057 -- d2 Suppress output of the error position flags for verbose form error
1058 -- messages. The messages are still interspersed in the listing, but
1059 -- without any error flags or extra blank lines. Also causes an extra
1060 -- <<< to be output at the right margin. This is intended to be the
1061 -- easiest format for checking conformance of ACATS B tests. This
1062 -- flag also suppresses the additional messages explaining why a
1063 -- non-static expression is non-static (see Sem_Eval.Why_Not_Static).
1064 -- This avoids having to worry about these messages in ACATS testing.
1065 -- Finally, this flag is also used for strict legality check, in
1066 -- particular it will generate an error instead a warning when
1067 -- encountering an unknown pragma.
1069 -- d3 Causes Comperr to dump the contents of the node for which an abort
1070 -- was detected (normally only the Node_Id of the node is output).
1072 -- d4 Inhibits automatic krunching of predefined library unit file names.
1073 -- Normally, as described in the spec of package Krunch, such files
1074 -- are automatically krunched to 8 characters, with special treatment
1075 -- of the prefixes Ada, System, and Interfaces. Setting this debug
1076 -- switch disables this special treatment.
1078 -- d5 Causes the tree read/write circuit to output detailed information
1079 -- tracking the data that is read and written element by element.
1081 -- d6 Normally access-to-unconstrained-array types are represented
1082 -- using fat (double) pointers. Using this debug flag causes them
1083 -- to default to thin. This can be used to test the performance
1084 -- implications of using thin pointers, and also to test that the
1085 -- compiler functions correctly with this choice.
1087 -- d7 Normally a -gnatl or -gnatv listing includes the time stamp of the
1088 -- source file and the time of the compilation. This debug flag can
1089 -- be used to suppress this output, and also suppresses the message
1090 -- with the version of the compiler. This is useful for regression
1091 -- tests which need to have consistent output.
1093 -- d8 This forces the packed stuff to generate code assuming the
1094 -- opposite endianness from the actual correct value. Useful in
1095 -- testing out code generation from the packed routines.
1097 -- d.1 Sets Opt.Unnest_Subprogram_Mode to enable unnesting of subprograms.
1098 -- This special pass does not actually unnest things, but it ensures
1099 -- that a nested procedure does not contain any uplevel references.
1100 -- See spec of Exp_Unst for full details.
1102 -- d.2 Allow statements within declarative parts. This is not usually
1103 -- allowed, but in some debugging contexts (e.g. testing the circuit
1104 -- for unnesting of procedures), it is useful to allow this.
1106 -- d.3 Output debugging information from Exp_Unst, including the name of
1107 -- any unreachable subprograms that get deleted.
1109 -- d.4 By default in case of an error during C generation, the .c or .h
1110 -- file is deleted. This flag keeps the C file.
1112 -- d.5 By default a subprogram imported generates a subprogram profile.
1113 -- This debug flag disables this generation when generating C code,
1114 -- assuming a proper #include will be used instead.
1116 -- d.6 By default the C back-end avoids declaring types that are not
1117 -- referenced by the generated C code. This debug flag restores the
1118 -- output of all the types.
1120 -- d.7 Indicates (to gnat2scil) that CodePeer is being invoked as a
1121 -- prover by the SPARK tools and that therefore gnat2scil should
1122 -- avoid SCIL generation strategies which can introduce soundness
1123 -- issues (e.g., assuming that a low bound of an array parameter
1124 -- of an unconstrained subtype belongs to the index subtype).
1126 -- d.8 By default calls to expression functions are always inlined.
1127 -- This debug flag turns off this behavior, making them subject
1128 -- to the usual inlining heuristics of the code generator.

1132 ------------------------------------------
1134 -- da Normally if there is an elaboration circularity, then in describing
1135 -- the cycle, links involving internal units are omitted, since they
1136 -- are irrelevant and confusing. This debug flag causes all links to
