449 | -- da Generate messages tracking semantic analyzer progress. A message | |
450 | -- is output showing each node as it gets analyzed, expanded, | |
451 | -- resolved, or evaluated. This option is useful for finding out | |
452 | -- exactly where a bomb during semantic analysis is occurring. | |
453 | ||
454 | -- db In Exp_Dbug, certain type names are encoded to include debugging | |
455 | -- information. This debug switch causes lines to be output showing | |
456 | -- the encodings used. | |
457 | ||
458 | -- dc List names of units as they are compiled. One line of output will | |
459 | -- be generated at the start of compiling each unit (package or | |
460 | -- subprogram). | |
461 | ||
462 | -- dd Dynamic allocation of tables messages generated. Each time a | |
463 | -- table is reallocated, a line is output indicating the expansion. | |
464 | ||
70482933 RK |
465 | -- de List the entity table |
466 | ||
467 | -- df Full tree/source print (includes withed units). Normally the tree | |
468 | -- output (dt) or recreated source output (dg,do,ds) includes only | |
469 | -- the main unit. If df is set, then the output in either case | |
470 | -- includes all compiled units (see also dg,do,ds,dt). Note that to | |
d8d7e809 | 471 | -- be effective, this switch must be used in combination with one or |
70482933 RK |
472 | -- more of dt, dg, do or ds. |
473 | ||
70482933 RK |
474 | -- dg Print the source recreated from the generated tree. In the case |
475 | -- where the tree has been rewritten this output includes only the | |
476 | -- generated code, not the original code (see also df,do,ds,dz). | |
477 | -- This flag differs from -gnatG in that the output also includes | |
478 | -- non-source generated null statements, and freeze nodes, which | |
479 | -- are normally omitted in -gnatG mode. | |
480 | ||
70482933 RK |
481 | -- dh Generates a table at the end of a compilation showing how the hash |
482 | -- table chains built by the Namet package are loaded. This is useful | |
483 | -- in ensuring that the hashing algorithm (in Namet.Hash) is working | |
484 | -- effectively with typical sets of program identifiers. | |
485 | ||
70482933 RK |
486 | -- di Generate messages for visibility linking/delinking |
487 | ||
488 | -- dj Suppress "junk null check" for access parameters. This flag permits | |
489 | -- Ada programs to pass null parameters to access parameters, and to | |
490 | -- explicitly check such access values against the null literal. | |
491 | -- Neither of these is valid Ada, but both were allowed in versions of | |
492 | -- GNAT before 3.10, so this switch can ease the transition process. | |
493 | ||
70482933 RK |
494 | -- dk Immediate kill on abort. Normally on an abort (i.e. a call to |
495 | -- Comperr.Compiler_Abort), the GNATBUG message is not given if | |
496 | -- there is a previous error. This debug switch bypasses this test | |
497 | -- and gives the message unconditionally (useful for debugging). | |
498 | ||
70482933 RK |
499 | -- dl Generate unit load trace messages. A line of traceback output is |
500 | -- generated each time a request is made to the library manager to | |
501 | -- load a new unit. | |
502 | ||
c1025b4e AC |
503 | -- dm Prevent special frontend inlining in GNATprove mode. In some cases, |
504 | -- some subprogram calls are inlined in GNATprove mode in order to | |
505 | -- facilitate formal verification. This debug switch prevents that | |
506 | -- inlining to happen. | |
507 | ||
70482933 RK |
508 | -- dn Generate messages for node/list allocation. Each time a node or |
509 | -- list header is allocated, a line of output is generated. Certain | |
510 | -- other basic tree operations also cause a line of output to be | |
511 | -- generated. This option is useful in seeing where the parser is | |
5e39baa6 | 512 | -- blowing up. |
70482933 | 513 | |
70482933 RK |
514 | -- do Print the source recreated from the generated tree. In the case |
515 | -- where the tree has been rewritten, this output includes only the | |
516 | -- original code, not the generated code (see also df,dg,ds,dz). | |
517 | ||
518 | -- dp Generate messages for parser scope stack push/pops. A line of | |
519 | -- output by the parser each time the parser scope stack is either | |
520 | -- pushed or popped. Useful in debugging situations where the | |
521 | -- parser scope stack ends up incorrectly synchronized | |
522 | ||
07fc65c4 GB |
523 | -- dq In layout version 1.38, 2002/01/12, a circuit was implemented |
524 | -- to give decent default alignment to short records that had no | |
525 | -- specific alignment set. This debug option restores the previous | |
526 | -- behavior of giving such records poor alignments, typically 1. | |
527 | -- This may be useful in dealing with transition. | |
528 | ||
70482933 RK |
529 | -- dr Generate parser resynchronization messages. Normally the parser |
530 | -- resynchronizes quietly. With this debug option, two messages | |
531 | -- are generated, one when the parser starts a resynchronization | |
532 | -- skip, and another when it resumes parsing. Useful in debugging | |
533 | -- inadequate error recovery situations. | |
534 | ||
535 | -- ds Print the source recreated from the generated tree. In the case | |
536 | -- where the tree has been rewritten this output includes both the | |
537 | -- generated code and the original code with the generated code | |
538 | -- being enlosed in curly brackets (see also df,do,ds,dz) | |
539 | ||
540 | -- dt Print full tree. The generated tree is output (see also df,dy) | |
541 | ||
542 | -- du Uncheck categorization pragmas. This debug switch causes the | |
cbc61965 AC |
543 | -- elaboration control pragmas (Pure, Preelaborate, etc.) and the |
544 | -- categorization pragmas (Shared_Passive, Remote_Types, etc.) to be | |
545 | -- ignored, so that normal checks are not made (this is particularly | |
546 | -- useful for adding temporary debugging code to units that have | |
547 | -- pragmas that are inconsistent with the debugging code added). | |
70482933 | 548 | |
fbf5a39b AC |
549 | -- dv Output trace of overload resolution. Outputs messages for |
550 | -- overload attempts that involve cascaded errors, or where | |
cbc61965 | 551 | -- an interpretation is incompatible with the context. |
fbf5a39b | 552 | |
70482933 | 553 | -- dw Write semantic scope stack messages. Each time a scope is created |
a99ada67 | 554 | -- or removed, a message is output (see the Sem_Ch8.Push_Scope and |
70482933 RK |
555 | -- Sem_Ch8.Pop_Scope subprograms). |
556 | ||
557 | -- dx Force expansion on, even if no code being generated. Normally the | |
558 | -- expander is inhibited if no code is generated. This switch forces | |
559 | -- expansion to proceed normally even if the backend is not being | |
560 | -- called. This is particularly useful for debugging purposes when | |
561 | -- using the front-end only version of the compiler (which normally | |
562 | -- would never do any expansion). | |
563 | ||
564 | -- dy Print tree of package Standard. Normally the tree print out does | |
565 | -- not include package Standard, even if the -df switch is set. This | |
566 | -- switch forces output of the internal tree built for Standard. | |
567 | ||
568 | -- dz Print source of package Standard. Normally the source print out | |
569 | -- does not include package Standard, even if the -df switch is set. | |
570 | -- This switch forces output of the source recreated from the internal | |
9596236a AC |
571 | -- tree built for Standard. Note that this differs from -gnatS in |
572 | -- that it prints from the actual tree using the normal Sprint | |
573 | -- circuitry for printing trees. | |
70482933 RK |
574 | |
575 | -- dA Forces output of representation information, including full | |
576 | -- information for all internal type and object entities, as well | |
fbf5a39b | 577 | -- as all user defined type and object entities including private |
a4c1cd80 | 578 | -- and incomplete types. This debug switch also automatically sets |
1c912574 | 579 | -- the equivalent of -gnatRm. |
70482933 RK |
580 | |
581 | -- dB Output debug encodings for types and variants. See Exp_Dbug for | |
582 | -- exact form of the generated output. | |
583 | ||
fbf5a39b AC |
584 | -- dC Output trace information showing the decisions made during |
585 | -- check suppression activity in unit Checks. | |
586 | ||
587 | -- dD Delete new elaboration checks. This flag causes GNAT to return | |
588 | -- to the 3.13a elaboration semantics, and to suppress the fixing | |
589 | -- of two bugs. The first is in the context of inner routines in | |
590 | -- dynamic elaboration mode, when the subprogram we are in was | |
591 | -- called at elaboration time by a unit that was also compiled with | |
592 | -- dynamic elaboration checks. In this case, if A calls B calls C, | |
593 | -- and all are in different units, we need an elaboration check at | |
594 | -- each call. These nested checks were only put in recently (see | |
595 | -- version 1.80 of Sem_Elab) and we provide this debug flag to | |
596 | -- revert to the previous behavior in case of regressions. The | |
597 | -- other behavior reverted by this flag is the treatment of the | |
598 | -- Elaborate_Body pragma in static elaboration mode. This used to | |
599 | -- be treated as not needing elaboration checking, but in fact in | |
600 | -- general Elaborate_All is still required because of nested calls. | |
601 | ||
70482933 | 602 | -- dE Apply compile time elaboration checking for with relations between |
4bfe4a99 | 603 | -- predefined units. Normally no checks are made. |
70482933 | 604 | |
d99ef225 YM |
605 | -- dF Disable the new SPARK checking rules for pointer aliasing. This is |
606 | -- only activated as part of GNATprove mode and on SPARK code. Now | |
607 | -- that pointer support is part of the official SPARK language, this | |
608 | -- switch allows reverting to the previous version of GNATprove | |
609 | -- rejecting pointers. | |
fb69239a | 610 | |
fbf5a39b AC |
611 | -- dG Generate all warnings. Normally Errout suppresses warnings on |
612 | -- units that are not part of the main extended source, and also | |
613 | -- suppresses warnings on instantiations in the main extended | |
614 | -- source that duplicate warnings already posted on the template. | |
615 | -- This switch stops both kinds of deletion and causes Errout to | |
616 | -- post all warnings sent to it. | |
617 | ||
618 | -- dH Inhibit call to gigi. This is useful for testing front end data | |
619 | -- layout, and may be useful in other debugging situations where | |
620 | -- you do not want gigi to intefere with the testing. | |
621 | ||
b99282c4 RD |
622 | -- dI Inhibit internal name numbering in gnatDG listing. Any sequence of |
623 | -- the form <uppercase-letter><digits><lowercase-letter> appearing in | |
624 | -- a name is replaced by <uppercase-letter>...<lowercase-letter>. This | |
625 | -- is used in the fixed bugs run to minimize system and version | |
626 | -- dependency in filed -gnatD or -gnatG output. | |
70482933 | 627 | |
f63adaa7 AC |
628 | -- dJ Prepend the name of the enclosing subprogram in compiler messages |
629 | -- (errors, warnings, style checks). This is useful in particular to | |
630 | -- integrate compiler warnings in static analysis tools such as | |
631 | -- CodePeer. | |
632 | ||
fbf5a39b AC |
633 | -- dK Kill all error messages. This debug flag suppresses the output |
634 | -- of all error messages. It is used in regression tests where the | |
635 | -- error messages are target dependent and irrelevant. | |
636 | ||
90e491a7 | 637 | -- dL The compiler ignores calls in instances and invoke subprograms |
c581c520 PMR |
638 | -- which are external to the instance for both the static and dynamic |
639 | -- elaboration models. | |
70482933 | 640 | |
fbf5a39b AC |
641 | -- dM Assume all variables have been modified, and ignore current value |
642 | -- indications. This debug flag disconnects the tracking of constant | |
643 | -- values (see Exp_Ch2.Expand_Current_Value). | |
644 | ||
bde33286 | 645 | -- dN Do not generate file name information in exception messages |
fbf5a39b | 646 | |
70482933 RK |
647 | -- dO Output immediate error messages. This causes error messages to |
648 | -- be output as soon as they are generated (disconnecting several | |
649 | -- circuits for improvement of messages, deletion of duplicate | |
650 | -- messages etc). Useful to diagnose compiler bombs caused by | |
651 | -- erroneous handling of error situations | |
652 | ||
653 | -- dP Do not check for controlled objects in preelaborable packages. | |
654 | -- RM 10.2.1(9) forbids the use of library level controlled objects | |
655 | -- in preelaborable packages, but this restriction is a huge pain, | |
656 | -- especially in the predefined library units. | |
657 | ||
872dae48 AC |
658 | -- dQ Use old method for determining what goes on the secondary stack. |
659 | -- This disables some newer optimizations. The intent is to use this | |
660 | -- temporarily to measure before/after efficiency. ???Remove this | |
661 | -- when we are done (see Sem_Util.Requires_Transient_Scope). | |
662 | ||
70482933 RK |
663 | -- dR Bypass the check for a proper version of s-rpc being present |
664 | -- to use the -gnatz? switch. This allows debugging of the use | |
665 | -- of stubs generation without needing to have GLADE (or some | |
666 | -- other PCS installed). | |
667 | ||
668 | -- dS Omit conversion of fpt numbers to exact machine numbers in | |
669 | -- non-static evaluation contexts (see Check_Non_Static_Context). | |
670 | -- This is intended for testing out timing problems with this | |
671 | -- conversion circuit. | |
672 | ||
673 | -- dT Similar to dS, but omits the conversions only in the case where | |
674 | -- the parent is not a constant declaration. | |
675 | ||
676 | -- dU Enable garbage collection of unreachable entities. This enables | |
677 | -- both the reachability analysis and changing the Is_Public and | |
678 | -- Is_Eliminated flags. | |
679 | ||
680 | -- dV Enable viewing of all symbols in debugger. Causes debug information | |
681 | -- to be generated for all symbols, including internal symbols. This | |
682 | -- is enabled by default for -gnatD, but this switch allows this to | |
683 | -- be enabled without generating modified source files. Note that the | |
684 | -- use of -gnatdV ensures in the dwarf/elf case that all symbols that | |
685 | -- are present in the elf tables are also in the dwarf tables (which | |
fbf5a39b AC |
686 | -- seems to be required by some tools). Another effect of dV is to |
687 | -- generate full qualified names, including internal names generated | |
688 | -- for blocks and loops. | |
689 | ||
690 | -- dW Disable warnings when a possibly uninitialized scalar value is | |
691 | -- passed to an IN OUT parameter of a procedure. This usage is a | |
692 | -- quite improper bounded error [erroneous in Ada 83] situation, | |
693 | -- and would normally generate a warning. However, to ease the | |
694 | -- task of transitioning incorrect legacy code, we provide this | |
695 | -- undocumented feature for suppressing these warnings. | |
70482933 | 696 | |
fbf5a39b AC |
697 | -- dY Enable configurable run-time mode, just as though the System file |
698 | -- had Configurable_Run_Time_Mode set to True. This is useful in | |
699 | -- testing high integrity mode. | |
700 | ||
b99282c4 RD |
701 | -- dZ Generate listing showing the contents of the dispatch tables. Each |
702 | -- line has an internally generated number used for references between | |
703 | -- tagged types and primitives. For each primitive the output has the | |
704 | -- following fields: | |
1b24ada5 | 705 | -- |
b99282c4 RD |
706 | -- - Letter 'P' or letter 's': The former indicates that this |
707 | -- primitive will be located in a primary dispatch table. The | |
708 | -- latter indicates that it will be located in a secondary | |
709 | -- dispatch table. | |
1b24ada5 | 710 | -- |
b99282c4 RD |
711 | -- - Name of the primitive. In case of predefined Ada primitives |
712 | -- the text "(predefined)" is added before the name, and these | |
713 | -- acronyms are used: SR (Stream_Read), SW (Stream_Write), SI | |
714 | -- (Stream_Input), SO (Stream_Output), DA (Deep_Adjust), DF | |
715 | -- (Deep_Finalize). In addition Oeq identifies the equality | |
716 | -- operator, and "_assign" the assignment. | |
1b24ada5 | 717 | -- |
b99282c4 RD |
718 | -- - If the primitive covers interface types, two extra fields |
719 | -- referencing other primitives are generated: "Alias" references | |
720 | -- the primitive of the tagged type that covers an interface | |
721 | -- primitive, and "AI_Alias" references the covered interface | |
722 | -- primitive. | |
1b24ada5 | 723 | -- |
b99282c4 RD |
724 | -- - The expression "at #xx" indicates the slot of the dispatch |
725 | -- table occupied by such primitive in its corresponding primary | |
726 | -- or secondary dispatch table. | |
1b24ada5 | 727 | -- |
b99282c4 RD |
