-------------------------------------------- + -- Documentation for Compiler Debug Flags -- + -------------------------------------------- + + -- 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. + + -- 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.f Suppress folding of static expressions. This of course results + -- in seriously non-conforming behavior, but is useful sometimes + -- when tracking down handling of complex expressions. + + -- 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 -- + ------------------------------------------ + + -- da Normally if there is an elaboration circularity, then in describing + -- the cycle, links involving internal units are omitted, since they + -- are irrelevant and confusing. This debug flag causes all links to + -- be listed, and is useful when diagnosing circularities introduced + -- by incorrect changes to the run-time library itself. + + -- 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' ..
