--------------------------------------------
-- 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.Push_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. Any sequence of
-- the form appearing in
-- a name is replaced by .... This
-- is used in the fixed bugs run to minimize system and version
-- dependency in filed -gnatD or -gnatG 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.
-- dQ needs full documentation ???
-- 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.
-- dZ Generate listing showing the contents of the dispatch tables. Each
-- line has an internally generated number used for references between
-- tagged types and primitives. For each primitive the output has the
-- following fields:
--
-- - Letter 'P' or letter 's': The former indicates that this
-- primitive will be located in a primary dispatch table. The
-- latter indicates that it will be located in a secondary
-- dispatch table.
--
-- - Name of the primitive. In case of predefined Ada primitives
-- the text "(predefined)" is added before the name, and these
-- acronyms are used: SR (Stream_Read), SW (Stream_Write), SI
-- (Stream_Input), SO (Stream_Output), DA (Deep_Adjust), DF
-- (Deep_Finalize). In addition Oeq identifies the equality
-- operator, and "_assign" the assignment.
--
-- - If the primitive covers interface types, two extra fields
-- referencing other primitives are generated: "Alias" references
-- the primitive of the tagged type that covers an interface
-- primitive, and "AI_Alias" references the covered interface
-- primitive.
--
-- - The expression "at #xx" indicates the slot of the dispatch
-- table occupied by such primitive in its corresponding primary
-- or secondary dispatch table.
--
-- - In case of abstract subprograms the text "is abstract" is
-- added at the end of the line.
-- d.c Generate inline concatenation, instead of calling one of the
-- System.Concat_n.Str_Concat_n routines in cases where the latter
-- routines would normally be called.
-- 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.g Enables conversion of a raise statement into a goto when the
-- relevant handler is statically determinable. For now we only try
-- this if this debug flag is set. Later we will enable this more
-- generally by default.
-- d.l Use Ada 95 semantics for limited function returns. This may be
-- used to work around the incompatibility introduced by AI-318-2.
-- It is useful only in -gnat05 mode.
-- d.m When -gnatl is used, the normal output includes full listings of
-- all files in the extended main source (body/spec/subunits). If this
-- debug switch is used, then the full listing is given only for the
-- main source (this corresponds to a previous behavior of -gnatl and
-- is used for running the ACATS tests).
-- d.r Forces the flag OK_To_Reorder_Components to be set in all record
-- base types that have no discriminants.
-- d.s Normally the compiler expands slice moves into loops if overlap
-- might be possible. This debug flag inhibits that expansion, and
-- the back end is expected to use an appropriate routine to handle
-- overlap, based on Forward_OK and Backwards_OK flags.
-- d.t The compiler has been modified (a fairly extensive modification)
-- to generate static dispatch tables for library level tagged types.
-- This debug switch disables this modification and reverts to the
-- previous dynamic construction of tables. It is there as a possible
-- work around if we run into trouble with the new implementation.
-- d.v Forces the flag OK_To_Reorder_Components to be set in all record
-- base types that have at least one discriminant (v = variant).
-- d.w This flag turns off the scanning of while loops to detect possible
-- infinite loops.
-- 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.
-- d.C Generate call to System.Concat_n.Str_Concat_n routines in cases
-- where we would normally generate inline concatenation code.
-- d.I Inspector mode. Relevant for VM_Target /= None. Try to generate
-- byte code, even in case of unsupported construct, for the sake
-- of static analysis tools.
-- d.S Force Optimize_Alignment (Space) mode as the default
-- d.T Force Optimize_Alignment (Time) mode as the default
-- 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.
-- do Use old elaboration order preference. The new preference rules
-- prefer specs with no bodies to specs with bodies, and between two
-- specs with bodies, prefers the one whose body is closer to being
-- able to be elaborated. This is a clear improvement, but we provide
-- this debug flag in case of regressions.
-- 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 gnatmake Debug Flags --
--------------------------------------------
-- df Only output file names, not path names, in log
-- dn Do not delete temporary files created by gnatmake 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.
---------------------------------------------
-- Documentation for gprbuild Debug Flags --
---------------------------------------------
-- dn Do not delete temporary files createed by gprbuild at the end
-- of execution, such as temporary config pragma files, mapping
-- files or project path files.
-- 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.
