-------------------------------------------- -- da Generate messages tracking semantic analyzer progress. A message -- is output showing each node as it gets analyzed, expanded, -- resolved, or evaluated. This option is useful for finding out -- exactly where a bomb during semantic analysis is occurring. -- db In Exp_Dbug, certain type names are encoded to include debugging -- information. This debug switch causes lines to be output showing -- the encodings used. -- dc List names of units as they are compiled. One line of output will -- be generated at the start of compiling each unit (package or -- subprogram). -- dd Dynamic allocation of tables messages generated. Each time a -- table is reallocated, a line is output indicating the expansion. -- de List the entity table -- df Full tree/source print (includes withed units). Normally the tree -- output (dt) or recreated source output (dg,do,ds) includes only -- the main unit. If df is set, then the output in either case -- includes all compiled units (see also dg,do,ds,dt). Note that to -- be effective, this swich must be used in combination with one or -- more of dt, dg, do or ds. -- dg Print the source recreated from the generated tree. In the case -- where the tree has been rewritten this output includes only the -- generated code, not the original code (see also df,do,ds,dz). -- This flag differs from -gnatG in that the output also includes -- non-source generated null statements, and freeze nodes, which -- are normally omitted in -gnatG mode. -- dh Generates a table at the end of a compilation showing how the hash -- table chains built by the Namet package are loaded. This is useful -- in ensuring that the hashing algorithm (in Namet.Hash) is working -- effectively with typical sets of program identifiers. -- di Generate messages for visibility linking/delinking -- dj Suppress "junk null check" for access parameters. This flag permits -- Ada programs to pass null parameters to access parameters, and to -- explicitly check such access values against the null literal. -- Neither of these is valid Ada, but both were allowed in versions of -- GNAT before 3.10, so this switch can ease the transition process. -- dk Immediate kill on abort. Normally on an abort (i.e. a call to -- Comperr.Compiler_Abort), the GNATBUG message is not given if -- there is a previous error. This debug switch bypasses this test -- and gives the message unconditionally (useful for debugging). -- dl Generate unit load trace messages. A line of traceback output is -- generated each time a request is made to the library manager to -- load a new unit. -- dm Some features are permitted only in OpenVMS ports of GNAT (e.g. -- the specification of passing by descriptor). Normally any use -- of these features will be flagged as an error, but this debug -- flag allows acceptance of these features in non OpenVMS ports. -- Of course they may not have any useful effect, and in particular -- attempting to generate code with this flag set may blow up. -- The flag also forces the use of 64-bits for Long_Integer. -- dn Generate messages for node/list allocation. Each time a node or -- list header is allocated, a line of output is generated. Certain -- other basic tree operations also cause a line of output to be -- generated. This option is useful in seeing where the parser is -- blowing up.; -- do Print the source recreated from the generated tree. In the case -- where the tree has been rewritten, this output includes only the -- original code, not the generated code (see also df,dg,ds,dz). -- dp Generate messages for parser scope stack push/pops. A line of -- output by the parser each time the parser scope stack is either -- pushed or popped. Useful in debugging situations where the -- parser scope stack ends up incorrectly synchronized -- dq In layout version 1.38, 2002/01/12, a circuit was implemented -- to give decent default alignment to short records that had no -- specific alignment set. This debug option restores the previous -- behavior of giving such records poor alignments, typically 1. -- This may be useful in dealing with transition. -- dr Generate parser resynchronization messages. Normally the parser -- resynchronizes quietly. With this debug option, two messages -- are generated, one when the parser starts a resynchronization -- skip, and another when it resumes parsing. Useful in debugging -- inadequate error recovery situations. -- ds Print the source recreated from the generated tree. In the case -- where the tree has been rewritten this output includes both the -- generated code and the original code with the generated code -- being enlosed in curly brackets (see also df,do,ds,dz) -- dt Print full tree. The generated tree is output (see also df,dy) -- du Uncheck categorization pragmas. This debug switch causes the -- categorization pragmas (Pure, Preelaborate etc) to be ignored -- so that normal checks are not made (this is particularly useful -- for adding temporary debugging code to units that have pragmas -- that are inconsistent with the debugging code added. -- dv Output trace of overload resolution. Outputs messages for -- overload attempts that involve cascaded errors, or where -- an interepretation is incompatible with the context. -- dw Write semantic scope stack messages. Each time a scope is created -- or removed, a message is output (see the Sem_Ch8.New_Scope and -- Sem_Ch8.Pop_Scope subprograms). -- dx Force expansion on, even if no code being generated. Normally the -- expander is inhibited if no code is generated. This switch forces -- expansion to proceed normally even if the backend is not being -- called. This is particularly useful for debugging purposes when -- using the front-end only version of the compiler (which normally -- would never do any expansion). -- dy Print tree of package Standard. Normally the tree print out does -- not include package Standard, even if the -df switch is set. This -- switch forces output of the internal tree built for Standard. -- dz Print source of package Standard. Normally the source print out -- does not include package Standard, even if the -df switch is set. -- This switch forces output of the source recreated from the internal -- tree built for Standard. Note that this differs from -gnatS in -- that it prints from the actual tree using the normal Sprint -- circuitry for printing trees. -- dA Forces output of representation information, including full -- information for all internal type and object entities, as well -- as all user defined type and object entities including private -- and incomplete types. This debug switch also automatically sets -- the equivalent of -gnatR3m. -- dB Output debug encodings for types and variants. See Exp_Dbug for -- exact form of the generated output. -- dC Output trace information showing the decisions made during -- check suppression activity in unit Checks. -- dD Delete new elaboration checks. This flag causes GNAT to return -- to the 3.13a elaboration semantics, and to suppress the fixing -- of two bugs. The first is in the context of inner routines in -- dynamic elaboration mode, when the subprogram we are in was -- called at elaboration time by a unit that was also compiled with -- dynamic elaboration checks. In this case, if A calls B calls C, -- and all are in different units, we need an elaboration check at -- each call. These nested checks were only put in recently (see -- version 1.80 of Sem_Elab) and we provide this debug flag to -- revert to the previous behavior in case of regressions. The -- other behavior reverted by this flag is the treatment of the -- Elaborate_Body pragma in static elaboration mode. This used to -- be treated as not needing elaboration checking, but in fact in -- general Elaborate_All is still required because of nested calls. -- dE Apply compile time elaboration checking for with relations between -- predefined units. Normally no checks are made (it seems that at -- least on the SGI, such checks run into trouble). -- dF Front end data layout enabled. Normally front end data layout -- is only enabled if the target parameter Backend_Layout is False. -- This debugging switch enables it unconditionally. -- dG Generate all warnings. Normally Errout suppresses warnings on -- units that are not part of the main extended source, and also -- suppresses warnings on instantiations in the main extended -- source that duplicate warnings already posted on the template. -- This switch stops both kinds of deletion and causes Errout to -- post all warnings sent to it. -- dH Inhibit call to gigi. This is useful for testing front end data -- layout, and may be useful in other debugging situations where -- you do not want gigi to intefere with the testing. -- dI Inhibit internal name numbering in gnatDG listing. For internal -- names of the form <uppercase-letters><digits><suffix>, the output -- will be modified to <uppercase-letters>...<suffix>. This is used -- in the fixed bugs run to minimize system and version dependency -- in filed -gnatDG output. -- dJ Generate debugging trace output for the JGNAT back end. This -- consists of symbolic Java Byte Code sequences for all generated -- classes plus additional information to indicate local variables -- and methods. -- dK Kill all error messages. This debug flag suppresses the output -- of all error messages. It is used in regression tests where the -- error messages are target dependent and irrelevant. -- dL Output trace information on elaboration checking. This debug -- switch causes output to be generated showing each call or -- instantiation as it is checked, and the progress of the recursive -- trace through calls at elaboration time. -- dM Assume all variables have been modified, and ignore current value -- indications. This debug flag disconnects the tracking of constant -- values (see Exp_Ch2.Expand_Current_Value). -- dN Do not generate file name information in exception messages. -- dO Output immediate error messages. This causes error messages to -- be output as soon as they are generated (disconnecting several -- circuits for improvement of messages, deletion of duplicate -- messages etc). Useful to diagnose compiler bombs caused by -- erroneous handling of error situations -- dP Do not check for controlled objects in preelaborable packages. -- RM 10.2.1(9) forbids the use of library level controlled objects -- in preelaborable packages, but this restriction is a huge pain, -- especially in the predefined library units. -- dR Bypass the check for a proper version of s-rpc being present -- to use the -gnatz? switch. This allows debugging of the use -- of stubs generation without needing to have GLADE (or some -- other PCS installed). -- dS Omit conversion of fpt numbers to exact machine numbers in -- non-static evaluation contexts (see Check_Non_Static_Context). -- This is intended for testing out timing problems with this -- conversion circuit. -- dT Similar to dS, but omits the conversions only in the case where -- the parent is not a constant declaration. -- dU Enable garbage collection of unreachable entities. This enables -- both the reachability analysis and changing the Is_Public and -- Is_Eliminated flags. -- dV Enable viewing of all symbols in debugger. Causes debug information -- to be generated for all symbols, including internal symbols. This -- is enabled by default for -gnatD, but this switch allows this to -- be enabled without generating modified source files. Note that the -- use of -gnatdV ensures in the dwarf/elf case that all symbols that -- are present in the elf tables are also in the dwarf tables (which -- seems to be required by some tools). Another effect of dV is to -- generate full qualified names, including internal names generated -- for blocks and loops. -- dW Disable warnings when a possibly uninitialized scalar value is -- passed to an IN OUT parameter of a procedure. This usage is a -- quite improper bounded error [erroneous in Ada 83] situation, -- and would normally generate a warning. However, to ease the -- task of transitioning incorrect legacy code, we provide this -- undocumented feature for suppressing these warnings. -- dX Enable frontend ZCX even when it is not supported. Equivalent to -- -gnatZ but without verifying that System.Front_End_ZCX_Support -- is set. This causes the front end to generate suitable tables -- for ZCX handling even when the runtime cannot handle ZCX. This -- is used for testing the front end for correct ZCX operation, and -- in particular is useful for multi-target testing. -- dY Enable configurable run-time mode, just as though the System file -- had Configurable_Run_Time_Mode set to True. This is useful in -- testing high integrity mode. -- d.x No exception handlers in generated code. This causes exception -- handlers to be eliminated from the generated code. They are still -- fully compiled and analyzed, they just get eliminated from the -- code generation step. -- d1 Error messages have node numbers where possible. Normally error -- messages have only source locations. This option is useful when -- debugging errors caused by expanded code, where the source location -- does not give enough information. -- d2 Suppress output of the error position flags for verbose form error -- messages. The messages are still interspersed in the listing, but -- without any error flags or extra blank lines. Also causes an extra -- <<< to be output at the right margin. This is intended to be the -- easiest format for checking conformance of ACATS B tests. This -- flag also suppresses the additional messages explaining why a -- non-static expression is non-static (see Sem_Eval.Why_Not_Static). -- This avoids having to worry about these messages in ACATS testing. -- d3 Causes Comperr to dump the contents of the node for which an abort -- was detected (normally only the Node_Id of the node is output). -- d4 Inhibits automatic krunching of predefined library unit file names. -- Normally, as described in the spec of package Krunch, such files -- are automatically krunched to 8 characters, with special treatment -- of the prefixes Ada, System, and Interfaces. Setting this debug -- switch disables this special treatment. -- d5 Causes the tree read/write circuit to output detailed information -- tracking the data that is read and written element by element. -- d6 Normally access-to-unconstrained-array types are represented -- using fat (double) pointers. Using this debug flag causes them -- to default to thin. This can be used to test the performance -- implications of using thin pointers, and also to test that the -- compiler functions correctly with this choice. -- d7 Normally a -gnatl or -gnatv listing includes the time stamp -- of the source file. This debug flag suppresses this output, -- and also suppresses the message with the version number. -- This is useful in certain regression tests. -- d8 This forces the packed stuff to generate code assuming the -- opposite endianness from the actual correct value. Useful in -- testing out code generation from the packed routines. ------------------------------------------ -- Documentation for Binder Debug Flags -- ------------------------------------------ -- dc List units as they are chosen. As units are selected for addition to -- the elaboration order, a line of output is generated showing which -- unit has been selected. -- de Similar to the effect of -e (output complete list of elaboration -- dependencies) except that internal units are included in the -- listing. -- di Normally gnatbind calls Read_Ali with Ignore_Errors set to -- False, since the binder really needs correct version ALI -- files to do its job. This debug flag causes Ignore_Errors -- mode to be set for the binder (and is particularly useful -- for testing ignore errors mode). -- dn List details of manipulation of Num_Pred values during execution of -- the algorithm used to determine a correct order of elaboration. This -- is useful in diagnosing any problems in its behavior. -- du List unit name and file name for each unit as it is read in -- dx Force the binder to read (and then ignore) the xref information -- in ali files (used to check that read circuit is working OK). ------------------------------------------------------------ -- Documentation for the Debug Flags used in package Make -- ------------------------------------------------------------ -- Please note that such flags apply to all of Make clients, -- such as gnatmake. -- dn Do not delete temporary files creates by Make at the end -- of execution, such as temporary config pragma files, mapping -- files or project path files. -- dp Prints the Q used by routine Make.Compile_Sources every time -- we go around the main compile loop of Make.Compile_Sources -- dq Prints source files as they are enqueued and dequeued in the Q -- used by routine Make.Compile_Sources. Useful to figure out the -- order in which sources are recompiled. -- dt When a time stamp mismatch has been found for an ALI file, -- display the source file name, the time stamp expected and -- the time stamp found. -- du List unit name and file name for each unit as it is read in -- dw Prints the list of units withed by the unit currently explored -- during the main loop of Make.Compile_Sources. ---------------------- -- Get_Debug_Flag_K -- ---------------------- function Get_Debug_Flag_K return Boolean is begin return Debug_Flag_K; end Get_Debug_Flag_K; -------------------- -- Set_Debug_Flag -- -------------------- procedure Set_Debug_Flag (C : Character; Val : Boolean := True) is subtype Dig is Character range '1' ..
