-------------------------------------------- 293 294 -- da Generate messages tracking semantic analyzer progress. A message 295 -- is output showing each node as it gets analyzed, expanded, 296 -- resolved, or evaluated. This option is useful for finding out 297 -- exactly where a bomb during semantic analysis is occurring. 298 299 -- db In Exp_Dbug, certain type names are encoded to include debugging 300 -- information. This debug switch causes lines to be output showing 301 -- the encodings used. 302 303 -- dc List names of units as they are compiled. One line of output will 304 -- be generated at the start of compiling each unit (package or 305 -- subprogram). 306 307 -- dd Dynamic allocation of tables messages generated. Each time a 308 -- table is reallocated, a line is output indicating the expansion. 309 310 -- de List the entity table 311 312 -- df Full tree/source print (includes withed units). Normally the tree 313 -- output (dt) or recreated source output (dg,do,ds) includes only 314 -- the main unit. If df is set, then the output in either case 315 -- includes all compiled units (see also dg,do,ds,dt). Note that to 316 -- be effective, this switch must be used in combination with one or 317 -- more of dt, dg, do or ds. 318 319 -- dg Print the source recreated from the generated tree. In the case 320 -- where the tree has been rewritten this output includes only the 321 -- generated code, not the original code (see also df,do,ds,dz). 322 -- This flag differs from -gnatG in that the output also includes 323 -- non-source generated null statements, and freeze nodes, which 324 -- are normally omitted in -gnatG mode. 325 326 -- dh Generates a table at the end of a compilation showing how the hash 327 -- table chains built by the Namet package are loaded. This is useful 328 -- in ensuring that the hashing algorithm (in Namet.Hash) is working 329 -- effectively with typical sets of program identifiers. 330 331 -- di Generate messages for visibility linking/delinking 332 333 -- dj Suppress "junk null check" for access parameters. This flag permits 334 -- Ada programs to pass null parameters to access parameters, and to 335 -- explicitly check such access values against the null literal. 336 -- Neither of these is valid Ada, but both were allowed in versions of 337 -- GNAT before 3.10, so this switch can ease the transition process. 338 339 -- dk Immediate kill on abort. Normally on an abort (i.e. a call to 340 -- Comperr.Compiler_Abort), the GNATBUG message is not given if 341 -- there is a previous error. This debug switch bypasses this test 342 -- and gives the message unconditionally (useful for debugging). 343 344 -- dl Generate unit load trace messages. A line of traceback output is 345 -- generated each time a request is made to the library manager to 346 -- load a new unit. 347 348 -- dm Prevent special frontend inlining in GNATprove mode. In some cases, 349 -- some subprogram calls are inlined in GNATprove mode in order to 350 -- facilitate formal verification. This debug switch prevents that 351 -- inlining to happen. 352 353 -- dn Generate messages for node/list allocation. Each time a node or 354 -- list header is allocated, a line of output is generated. Certain 355 -- other basic tree operations also cause a line of output to be 356 -- generated. This option is useful in seeing where the parser is 357 -- blowing up. 358 359 -- do Print the source recreated from the generated tree. In the case 360 -- where the tree has been rewritten, this output includes only the 361 -- original code, not the generated code (see also df,dg,ds,dz). 362 363 -- dp Generate messages for parser scope stack push/pops. A line of 364 -- output by the parser each time the parser scope stack is either 365 -- pushed or popped. Useful in debugging situations where the 366 -- parser scope stack ends up incorrectly synchronized 367 368 -- dq In layout version 1.38, 2002/01/12, a circuit was implemented 369 -- to give decent default alignment to short records that had no 370 -- specific alignment set. This debug option restores the previous 371 -- behavior of giving such records poor alignments, typically 1. 372 -- This may be useful in dealing with transition. 373 374 -- dr Generate parser resynchronization messages. Normally the parser 375 -- resynchronizes quietly. With this debug option, two messages 376 -- are generated, one when the parser starts a resynchronization 377 -- skip, and another when it resumes parsing. Useful in debugging 378 -- inadequate error recovery situations. 379 380 -- ds Print the source recreated from the generated tree. In the case 381 -- where the tree has been rewritten this output includes both the 382 -- generated code and the original code with the generated code 383 -- being enlosed in curly brackets (see also df,do,ds,dz) 384 385 -- dt Print full tree. The generated tree is output (see also df,dy) 386 387 -- du Uncheck categorization pragmas. This debug switch causes the 388 -- elaboration control pragmas (Pure, Preelaborate, etc.) and the 389 -- categorization pragmas (Shared_Passive, Remote_Types, etc.) to be 390 -- ignored, so that normal checks are not made (this is particularly 391 -- useful for adding temporary debugging code to units that have 392 -- pragmas that are inconsistent with the debugging code added). 393 394 -- dv Output trace of overload resolution. Outputs messages for 395 -- overload attempts that involve cascaded errors, or where 396 -- an interpretation is incompatible with the context. 397 398 -- dw Write semantic scope stack messages. Each time a scope is created 399 -- or removed, a message is output (see the Sem_Ch8.Push_Scope and 400 -- Sem_Ch8.Pop_Scope subprograms). 401 402 -- dx Force expansion on, even if no code being generated. Normally the 403 -- expander is inhibited if no code is generated. This switch forces 404 -- expansion to proceed normally even if the backend is not being 405 -- called. This is particularly useful for debugging purposes when 406 -- using the front-end only version of the compiler (which normally 407 -- would never do any expansion). 408 409 -- dy Print tree of package Standard. Normally the tree print out does 410 -- not include package Standard, even if the -df switch is set. This 411 -- switch forces output of the internal tree built for Standard. 412 413 -- dz Print source of package Standard. Normally the source print out 414 -- does not include package Standard, even if the -df switch is set. 415 -- This switch forces output of the source recreated from the internal 416 -- tree built for Standard. Note that this differs from -gnatS in 417 -- that it prints from the actual tree using the normal Sprint 418 -- circuitry for printing trees. 419 420 -- dA Forces output of representation information, including full 421 -- information for all internal type and object entities, as well 422 -- as all user defined type and object entities including private 423 -- and incomplete types. This debug switch also automatically sets 424 -- the equivalent of -gnatRm. 425 426 -- dB Output debug encodings for types and variants. See Exp_Dbug for 427 -- exact form of the generated output. 428 429 -- dC Output trace information showing the decisions made during 430 -- check suppression activity in unit Checks. 431 432 -- dD Delete new elaboration checks. This flag causes GNAT to return 433 -- to the 3.13a elaboration semantics, and to suppress the fixing 434 -- of two bugs. The first is in the context of inner routines in 435 -- dynamic elaboration mode, when the subprogram we are in was 436 -- called at elaboration time by a unit that was also compiled with 437 -- dynamic elaboration checks. In this case, if A calls B calls C, 438 -- and all are in different units, we need an elaboration check at 439 -- each call. These nested checks were only put in recently (see 440 -- version 1.80 of Sem_Elab) and we provide this debug flag to 441 -- revert to the previous behavior in case of regressions. The 442 -- other behavior reverted by this flag is the treatment of the 443 -- Elaborate_Body pragma in static elaboration mode. This used to 444 -- be treated as not needing elaboration checking, but in fact in 445 -- general Elaborate_All is still required because of nested calls. 446 447 -- dE Apply compile time elaboration checking for with relations between 448 -- predefined units. Normally no checks are made. 449 450 -- dF Perform the new SPARK checking rules for pointer aliasing. This is 451 -- only activated in GNATprove mode and on SPARK code. These rules are 452 -- not yet part of the official SPARK language, but are expected to be 453 -- included in a future version of SPARK. 454 455 -- dG Generate all warnings. Normally Errout suppresses warnings on 456 -- units that are not part of the main extended source, and also 457 -- suppresses warnings on instantiations in the main extended 458 -- source that duplicate warnings already posted on the template. 459 -- This switch stops both kinds of deletion and causes Errout to 460 -- post all warnings sent to it. 461 462 -- dH Inhibit call to gigi. This is useful for testing front end data 463 -- layout, and may be useful in other debugging situations where 464 -- you do not want gigi to intefere with the testing. 465 466 -- dI Inhibit internal name numbering in gnatDG listing. Any sequence of 467 -- the form <uppercase-letter><digits><lowercase-letter> appearing in 468 -- a name is replaced by <uppercase-letter>...<lowercase-letter>. This 469 -- is used in the fixed bugs run to minimize system and version 470 -- dependency in filed -gnatD or -gnatG output. 471 472 -- dJ Prepend the name of the enclosing subprogram in compiler messages 473 -- (errors, warnings, style checks). This is useful in particular to 474 -- integrate compiler warnings in static analysis tools such as 475 -- CodePeer. 476 477 -- dK Kill all error messages. This debug flag suppresses the output 478 -- of all error messages. It is used in regression tests where the 479 -- error messages are target dependent and irrelevant. 480 481 -- dL The compiler ignores calls in instances and invoke subprograms 482 -- which are external to the instance for both the static and dynamic 483 -- elaboration models. 484 485 -- dM Assume all variables have been modified, and ignore current value 486 -- indications. This debug flag disconnects the tracking of constant 487 -- values (see Exp_Ch2.Expand_Current_Value). 488 489 -- dN Do not generate file name information in exception messages 490 491 -- dO Output immediate error messages. This causes error messages to 492 -- be output as soon as they are generated (disconnecting several 493 -- circuits for improvement of messages, deletion of duplicate 494 -- messages etc). Useful to diagnose compiler bombs caused by 495 -- erroneous handling of error situations 496 497 -- dP Do not check for controlled objects in preelaborable packages. 498 -- RM 10.2.1(9) forbids the use of library level controlled objects 499 -- in preelaborable packages, but this restriction is a huge pain, 500 -- especially in the predefined library units. 501 502 -- dQ Use old method for determining what goes on the secondary stack. 503 -- This disables some newer optimizations. The intent is to use this 504 -- temporarily to measure before/after efficiency. ???Remove this 505 -- when we are done (see Sem_Util.Requires_Transient_Scope). 506 507 -- dR Bypass the check for a proper version of s-rpc being present 508 -- to use the -gnatz? switch. This allows debugging of the use 509 -- of stubs generation without needing to have GLADE (or some 510 -- other PCS installed). 511 512 -- dS Omit conversion of fpt numbers to exact machine numbers in 513 -- non-static evaluation contexts (see Check_Non_Static_Context). 514 -- This is intended for testing out timing problems with this 515 -- conversion circuit. 516 517 -- dT Similar to dS, but omits the conversions only in the case where 518 -- the parent is not a constant declaration. 519 520 -- dU Enable garbage collection of unreachable entities. This enables 521 -- both the reachability analysis and changing the Is_Public and 522 -- Is_Eliminated flags. 523 524 -- dV Enable viewing of all symbols in debugger. Causes debug information 525 -- to be generated for all symbols, including internal symbols. This 526 -- is enabled by default for -gnatD, but this switch allows this to 527 -- be enabled without generating modified source files. Note that the 528 -- use of -gnatdV ensures in the dwarf/elf case that all symbols that 529 -- are present in the elf tables are also in the dwarf tables (which 530 -- seems to be required by some tools). Another effect of dV is to 531 -- generate full qualified names, including internal names generated 532 -- for blocks and loops. 533 534 -- dW Disable warnings when a possibly uninitialized scalar value is 535 -- passed to an IN OUT parameter of a procedure. This usage is a 536 -- quite improper bounded error [erroneous in Ada 83] situation, 537 -- and would normally generate a warning. However, to ease the 538 -- task of transitioning incorrect legacy code, we provide this 539 -- undocumented feature for suppressing these warnings. 540 541 -- dY Enable configurable run-time mode, just as though the System file 542 -- had Configurable_Run_Time_Mode set to True. This is useful in 543 -- testing high integrity mode. 544 545 -- dZ Generate listing showing the contents of the dispatch tables. Each 546 -- line has an internally generated number used for references between 547 -- tagged types and primitives. For each primitive the output has the 548 -- following fields: 549 -- 550 -- - Letter 'P' or letter 's': The former indicates that this 551 -- primitive will be located in a primary dispatch table. The 552 -- latter indicates that it will be located in a secondary 553 -- dispatch table. 554 -- 555 -- - Name of the primitive. In case of predefined Ada primitives 556 -- the text "(predefined)" is added before the name, and these 557 -- acronyms are used: SR (Stream_Read), SW (Stream_Write), SI 558 -- (Stream_Input), SO (Stream_Output), DA (Deep_Adjust), DF 559 -- (Deep_Finalize). In addition Oeq identifies the equality 560 -- operator, and "_assign" the assignment. 561 -- 562 -- - If the primitive covers interface types, two extra fields 563 -- referencing other primitives are generated: "Alias" references 564 -- the primitive of the tagged type that covers an interface 565 -- primitive, and "AI_Alias" references the covered interface 566 -- primitive. 567 -- 568 -- - The expression "at #xx" indicates the slot of the dispatch 569 -- table occupied by such primitive in its corresponding primary 570 -- or secondary dispatch table. 571 -- 572 -- - In case of abstract subprograms the text "is abstract" is 573 -- added at the end of the line. 574 575 -- d.a Force Target_Strict_Alignment to True, even on targets where it 576 -- would normally be false. Can be used for testing strict alignment 577 -- circuitry in the compiler. 578 579 -- d.b Dump back end types. During Create_Standard, the back end is 580 -- queried for all available types. This option shows them. 581 582 -- d.c Generate inline concatenation, instead of calling one of the 583 -- System.Concat_n.Str_Concat_n routines in cases where the latter 584 -- routines would normally be called. 585 586 -- d.d Disable atomic synchronization for all atomic variable references. 587 -- Pragma Enable_Atomic_Synchronization is ignored. 588 589 -- d.e Enable atomic synchronization for all atomic variable references. 590 -- Pragma Disable_Atomic_Synchronization is ignored, and also the 591 -- compiler switch -gnated is ignored. 592 593 -- d.f Suppress folding of static expressions. This of course results 594 -- in seriously non-conforming behavior, but is useful sometimes 595 -- when tracking down handling of complex expressions. 596 597 -- d.g Enables conversion of a raise statement into a goto when the 598 -- relevant handler is statically determinable. For now we only try 599 -- this if this debug flag is set. Later we will enable this more 600 -- generally by default. 601 602 -- d.h Minimize the creation of public internal symbols for concatenation 603 -- by enforcing a secondary stack-like handling of the final result. 604 -- The target of the concatenation is thus constrained in place and 605 -- initialized with the result instead of acting as its alias. 606 607 -- d.i Ignore all occurrences of pragma Warnings in the sources. This can 608 -- be used in particular to disable Warnings (Off) to check if any of 609 -- these statements are inappropriate. 610 611 -- d.k If an error message contains a reference to a location in an 612 -- internal unit, then suppress the line number in this reference. 613 614 -- d.j Generate listing of frontend inlined calls and inline calls passed 615 -- to the backend. This is useful to locate skipped calls that must be 616 -- inlined by the frontend. 617 618 -- d.l Use Ada 95 semantics for limited function returns. This may be 619 -- used to work around the incompatibility introduced by AI-318-2. 620 -- It is useful only in Ada 2005 and later. 621 622 -- d.m When -gnatl is used, the normal output includes full listings of 623 -- all files in the extended main source (body/spec/subunits). If this 624 -- debug switch is used, then the full listing is given only for the 625 -- main source (this corresponds to a previous behavior of -gnatl and 626 -- is used for running the ACATS tests). 627 628 -- d.n Print source file names as they are loaded. This is useful if the 629 -- compiler has a bug -- these are the files that need to be included 630 -- in a bug report. 631 632 -- d.o Conservative elaboration order for indirect calls. This causes 633 -- P'Access to be treated as a call in more cases. 634 635 -- d.p In Ada 95 (or 83) mode, use original Ada 95 behavior for the 636 -- interpretation of component clauses crossing byte boundaries when 637 -- using the non-default bit order (i.e. ignore AI95-0133). 638 639 -- d.q If an array variable or constant is not modified in Ada code, and 640 -- is passed to an 'in' parameter of a foreign-convention subprogram, 641 -- and that subprogram modifies the array, the Ada compiler normally 642 -- assumes that the array is not modified. This option suppresses such 643 -- optimizations. This option should not be used; the correct solution 644 -- is to declare the parameter 'in out'. 645 646 -- d.r Do not reorder components in record types. 647 648 -- d.s The compiler no longer attempts to optimize the calls to secondary 649 -- stack management routines SS_Mark and SS_Release. As a result, each 650 -- transient block tasked with secondary stack management will fulfill 651 -- its role unconditionally. 652 653 -- d.s The compiler does not generate calls to secondary stack management 654 -- routines SS_Mark and SS_Release for a transient block when there is 655 -- an enclosing scoping construct which already manages the secondary 656 -- stack. 657 658 -- d.t The compiler has been modified (a fairly extensive modification) 659 -- to generate static dispatch tables for library level tagged types. 660 -- This debug switch disables this modification and reverts to the 661 -- previous dynamic construction of tables. It is there as a possible 662 -- work around if we run into trouble with the new implementation. 663 664 -- d.u Sets Modify_Tree_For_C mode in which tree is modified to make it 665 -- easier to generate code using a C compiler. 666 667 -- d.v This flag enforces the elaboration rules defined in the SPARK 668 -- Reference Manual, chapter 7.7, to all SPARK code within a unit. As 669 -- a result, constructs which violate the rules in chapter 7.7 are no 670 -- longer accepted, even if the implementation is able to statically 671 -- ensure that accepting these constructs does not introduce the 672 -- possibility of failing an elaboration check. 673 674 -- d.w This flag turns off the scanning of loops to detect possible 675 -- infinite loops. 676 677 -- d.x No exception handlers in generated code. This causes exception 678 -- handlers to be eliminated from the generated code. They are still 679 -- fully compiled and analyzed, they just get eliminated from the 680 -- code generation step. 681 682 -- d.y Disable implicit pragma Elaborate_All on task bodies. When a task 683 -- body calls a procedure in the same package, and that procedure 684 -- calls a procedure in another package, the static elaboration 685 -- machinery adds an implicit Elaborate_All on the other package. This 686 -- switch disables the addition of the implicit pragma in such cases. 687 688 -- d.z Restore previous front-end support for Inline_Always. In default 689 -- mode, for targets that use the GCC back end, Inline_Always is 690 -- handled by the back end. Use of this switch restores the previous 691 -- handling of Inline_Always by the front end on such targets. For the 692 -- targets that do not use the GCC back end, this switch is ignored. 693 694 -- d.A There seems to be a problem with ASIS if we activate the circuit 695 -- for reading and writing the aspect specification hash table, so 696 -- for now, this is controlled by the debug flag d.A. The hash table 697 -- is only written and read if this flag is set. 698 699 -- d.B Generate a bug box when we see an abort_statement, even though 700 -- there is no bug. Useful for testing Comperr.Compiler_Abort: write 701 -- some code containing an abort_statement, and compile it with 702 -- -gnatd.B. There is nothing special about abort_statements; it just 703 -- provides a way to control where the bug box is generated. See "when 704 -- N_Abort_Statement" in package body Expander. 705 706 -- d.C Generate call to System.Concat_n.Str_Concat_n routines in cases 707 -- where we would normally generate inline concatenation code. 708 709 -- d.D For compatibility with some Ada 95 compilers implementing only 710 -- one feature of Ada 2005 (overriding keyword), disable errors on use 711 -- of overriding keyword in Ada 95 mode. 712 713 -- d.E Turn selected errors into warnings. This debug switch causes a 714 -- specific set of error messages into warnings. Setting this switch 715 -- causes Opt.Error_To_Warning to be set to True. The intention is 716 -- that this be used for messages representing upwards incompatible 717 -- changes to Ada 2012 that cause previously correct programs to be 718 -- treated as illegal now. The following cases are affected: 719 -- 720 -- Errors relating to overlapping subprogram parameters for cases 721 -- other than IN OUT parameters to functions. 722 -- 723 -- Errors relating to the new rules about not defining equality 724 -- too late so that composition of equality can be assured. 725 -- 726 -- Errors relating to overriding indicators on protected subprogram 727 -- bodies (not an Ada 2012 incompatibility, but might cause errors 728 -- for existing programs assuming they were legal because GNAT 729 -- formerly allowed them). 730 731 -- d.F Sets GNATprove_Mode to True. This allows debugging the frontend in 732 -- the special mode used by GNATprove. 733 734 -- d.G Previously the compiler ignored calls via generic formal parameters 735 -- when doing the analysis for the static elaboration model. This is 736 -- now fixed, but we provide this debug flag to revert to the previous 737 -- situation of ignoring such calls to aid in transition. 738 739 -- d.H Sets ASIS_GNSA_Mode to True. This signals the front end to suppress 740 -- the call to gigi in ASIS_Mode. 741 742 -- d.I Do not ignore enum representation clauses in CodePeer mode. 743 -- The default of ignoring representation clauses for enumeration 744 -- types in CodePeer is good for the majority of Ada code, but in some 745 -- cases being able to change this default might be useful to remove 746 -- some false positives. 747 748 -- d.J Relaxed rules for pragma No_Return. A pragma No_Return is illegal 749 -- if it applies to a body. This switch disables the legality check 750 -- for that. If the procedure does in fact return normally, execution 751 -- is erroneous, and therefore unpredictable. 752 753 -- d.K Enable generation of contract-only procedures in CodePeer mode and 754 -- report a warning on subprograms for which the contract-only body 755 -- cannot be built. Currently reported on subprograms defined in 756 -- nested package specs that have some formal (or return type) whose 757 -- type is a private type defined in some enclosing package and that 758 -- have pre/postconditions. 759 760 -- d.L Normally the front end generates special expansion for conditional 761 -- expressions of a limited type. This debug flag removes this special 762 -- case expansion, leaving it up to the back end to handle conditional 763 -- expressions correctly. 764 765 -- d.M Relaxed RM semantics. This flag sets Opt.Relaxed_RM_Semantics 766 -- See Opt.Relaxed_RM_Semantics for more details. 767 768 -- d.N Enlarge entities by one node (but don't attempt to use this extra 769 -- node for storage of any flags or fields). This can be used to do 770 -- experiments on the impact of increasing entity sizes. 771 772 -- d.O Dump internal SCO tables. Before outputting the SCO information to 773 -- the ALI file, the internal SCO tables (SCO_Table/SCO_Unit_Table) 774 -- are dumped for debugging purposes. 775 776 -- d.P Previous non-optimized handling of length comparisons. Setting this 777 -- flag inhibits the effect of Optimize_Length_Comparison in Exp_Ch4. 778 -- This is there in case we find a situation where the optimization 779 -- malfunctions, to provide a work around. 780 781 -- d.Q Previous incomplete style checks for binary operators. Style checks 782 -- for token separation rules were incomplete and have been made 783 -- compliant with the documentation. For example, no warning was 784 -- issued for expressions such as 16-One or "A"&"B". Setting this flag 785 -- inhibits these new checks. 786 787 -- d.R As documented in lib-writ.ads, restrictions in the ali file can 788 -- have two forms, positional and named. The named notation is the 789 -- current preferred form, but the use of this debug switch will force 790 -- the use of the obsolescent positional form. 791 792 -- d.S Force Optimize_Alignment (Space) mode as the default 793 794 -- d.T Force Optimize_Alignment (Time) mode as the default 795 796 -- d.U Ignore indirect calls for static elaboration. The static 797 -- elaboration model is conservative, especially regarding indirect 798 -- calls. If you say Proc'Access, it will assume you might call 799 -- Proc. This can cause elaboration cycles at bind time. This flag 800 -- reverts to the behavior of earlier compilers, which ignored 801 -- indirect calls. 802 803 -- d.V Do not verify the validity of SCIL files (CodePeer mode). When 804 -- generating SCIL files for CodePeer, by default we verify that the 805 -- SCIL is well formed before saving it on disk. This switch can be 806 -- used to disable this checking, either to improve speed or to shut 807 -- down a false positive detected during the verification. 808 809 -- d.W Print out debugging information for Walk_Library_Items, including 810 -- the order in which units are walked. This is primarily for use in 811 -- debugging CodePeer mode. 812 813 -- d.X A previous version of GNAT allowed indexing aspects to be redefined 814 -- on derived container types, while the default iterator was 815 -- inherited from the parent type. This nonstandard extension is 816 -- preserved temporarily for use by the modeling project under debug 817 -- flag d.X. 818 819 -- d.Z Normally we always enable expansion in configurable run-time mode 820 -- to make sure we get error messages about unsupported features even 821 -- when compiling in -gnatc mode. But expansion is turned off in this 822 -- case if debug flag -gnatd.Z is used. This is to deal with the case 823 -- where we discover difficulties in this new processing. 824 825 -- d_a The compiler stops the examination of a task body once it reaches 826 -- an accept or select statement for the static elaboration model. The 827 -- behavior is similar to that of No_Entry_Calls_In_Elaboration_Code, 828 -- but does not penalize actual entry calls in elaboration code. 829 830 -- d_e The compiler ignores simple entry calls, asynchronous transfer of 831 -- control, conditional entry calls, timed entry calls, and requeue 832 -- statements in both the static and dynamic elaboration models. 833 834 -- d_f Issue info messages related to GNATprove usage to help users 835 -- understand analysis results. By default these are not issued as 836 -- beginners find them confusing. Set automatically by GNATprove when 837 -- switch --info is used. 838 839 -- d_i The compiler ignores calls and task activations when they target a 840 -- subprogram or task type defined in an external instance for both 841 -- the static and dynamic elaboration models. 842 843 -- d_p The compiler ignores calls to subprograms which verify the run-time 844 -- semantics of invariants and postconditions in both the static and 845 -- dynamic elaboration models. 846 847 -- d_s The compiler stops the examination of a task body once it reaches 848 -- a call to routine Ada.Synchronous_Task_Control.Suspend_Until_True 849 -- or Ada.Synchronous_Barriers.Wait_For_Release. 850 851 -- d_A Do not generate ALI files by setting Opt.Disable_ALI_File. 852 853 -- d_L Output trace information on elaboration checking. This debug switch 854 -- causes output to be generated showing each call or instantiation as 855 -- it is checked, and the progress of the recursive trace through 856 -- elaboration calls at compile time. 857 858 -- d1 Error messages have node numbers where possible. Normally error 859 -- messages have only source locations. This option is useful when 860 -- debugging errors caused by expanded code, where the source location 861 -- does not give enough information. 862 863 -- d2 Suppress output of the error position flags for verbose form error 864 -- messages. The messages are still interspersed in the listing, but 865 -- without any error flags or extra blank lines. Also causes an extra 866 -- <<< to be output at the right margin. This is intended to be the 867 -- easiest format for checking conformance of ACATS B tests. This 868 -- flag also suppresses the additional messages explaining why a 869 -- non-static expression is non-static (see Sem_Eval.Why_Not_Static). 870 -- This avoids having to worry about these messages in ACATS testing. 871 872 -- d3 Causes Comperr to dump the contents of the node for which an abort 873 -- was detected (normally only the Node_Id of the node is output). 874 875 -- d4 Inhibits automatic krunching of predefined library unit file names. 876 -- Normally, as described in the spec of package Krunch, such files 877 -- are automatically krunched to 8 characters, with special treatment 878 -- of the prefixes Ada, System, and Interfaces. Setting this debug 879 -- switch disables this special treatment. 880 881 -- d5 Causes the tree read/write circuit to output detailed information 882 -- tracking the data that is read and written element by element. 883 884 -- d6 Normally access-to-unconstrained-array types are represented 885 -- using fat (double) pointers. Using this debug flag causes them 886 -- to default to thin. This can be used to test the performance 887 -- implications of using thin pointers, and also to test that the 888 -- compiler functions correctly with this choice. 889 890 -- d7 Normally a -gnatl or -gnatv listing includes the time stamp of the 891 -- source file and the time of the compilation. This debug flag can 892 -- be used to suppress this output, and also suppresses the message 893 -- with the version of the compiler. This is useful for regression 894 -- tests which need to have consistent output. 895 896 -- d8 This forces the packed stuff to generate code assuming the 897 -- opposite endianness from the actual correct value. Useful in 898 -- testing out code generation from the packed routines. 899 900 -- d9 This allows lock free implementation for protected objects 901 -- (see Exp_Ch9). 902 903 -- d.1 Sets Opt.Unnest_Subprogram_Mode to enable unnesting of subprograms. 904 -- This special pass does not actually unnest things, but it ensures 905 -- that a nested procedure does not contain any uplevel references. 906 -- See spec of Exp_Unst for full details. 907 908 -- d.2 Allow statements within declarative parts. This is not usually 909 -- allowed, but in some debugging contexts (e.g. testing the circuit 910 -- for unnesting of procedures), it is useful to allow this. 911 912 -- d.3 Output debugging information from Exp_Unst, including the name of 913 -- any unreachable subprograms that get deleted. 914 915 -- d.4 By default in case of an error during C generation, the .c or .h 916 -- file is deleted. This flag keeps the C file. 917 918 -- d.5 By default a subprogram imported generates a subprogram profile. 919 -- This debug flag disables this generation when generating C code, 920 -- assuming a proper #include will be used instead. 921 922 -- d.6 By default the C back-end avoids declaring types that are not 923 -- referenced by the generated C code. This debug flag restores the 924 -- output of all the types. 925 926 -- d.7 Indicates (to gnat2scil) that CodePeer is being invoked as a 927 -- prover by the SPARK tools and that therefore gnat2scil should 928 -- avoid SCIL generation strategies which can introduce soundness 929 -- issues (e.g., assuming that a low bound of an array parameter 930 -- of an unconstrained subtype belongs to the index subtype). 931 932 -- d.9 Enable build-in-place for function calls returning some nonlimited 933 -- types. 934 935 ------------------------------------------ 936 -- Documentation for Binder Debug Flags -- 937 ------------------------------------------ 938 939 -- da Normally if there is an elaboration circularity, then in describing 940 -- the cycle, links involving internal units are omitted, since they 941 -- are irrelevant and confusing. This debug flag causes all links to 942 -- be listed, and is useful when diagnosing circularities introduced 943 -- by incorrect changes to the run-time library itself. 944 945 -- db Output debug information from Better_Choice in Binde, which uses 946 -- various heuristics to determine elaboration order in cases where 947 -- multiple orders are valid. 948 949 -- dc List units as they are chosen. As units are selected for addition to 950 -- the elaboration order, a line of output is generated showing which 951 -- unit has been selected. 952 953 -- de Similar to the effect of -e (output complete list of elaboration 954 -- dependencies) except that internal units are included in the 955 -- listing. 956 957 -- di Normally gnatbind calls Read_Ali with Ignore_Errors set to 958 -- False, since the binder really needs correct version ALI 959 -- files to do its job. This debug flag causes Ignore_Errors 960 -- mode to be set for the binder (and is particularly useful 961 -- for testing ignore errors mode). 962 963 -- dn List details of manipulation of Num_Pred values during execution of 964 -- the algorithm used to determine a correct order of elaboration. This 965 -- is useful in diagnosing any problems in its behavior. 966 967 -- do Use older elaboration order preference. The new preference rules 968 -- prefer specs with no bodies to specs with bodies, and between two 969 -- specs with bodies, prefers the one whose body is closer to being 970 -- able to be elaborated. This is a clear improvement, but we provide 971 -- this debug flag in case of regressions. Note: -do is even older 972 -- than -dp. 973 974 -- dp Use old elaboration order preference.
