-- 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 switch 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 Prevent special frontend inlining in GNATprove mode. In some cases,
-- some subprogram calls are inlined in GNATprove mode in order to
-- facilitate formal verification. This debug switch prevents that
-- inlining to happen.
-- 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
-- elaboration control pragmas (Pure, Preelaborate, etc.) and the
-- categorization pragmas (Shared_Passive, Remote_Types, 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 interpretation 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 -gnatRm.
-- 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.
-- 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 Prepend the name of the enclosing subprogram in compiler messages
-- (errors, warnings, style checks). This is useful in particular to
-- integrate compiler warnings in static analysis tools such as
-- CodePeer.
-- 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 The compiler ignores calls in instances and invoke subprograms
-- which are external to the instance for both the static and dynamic
-- elaboration models.
-- 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 Use old method for determining what goes on the secondary stack.
-- This disables some newer optimizations. The intent is to use this
-- temporarily to measure before/after efficiency. ???Remove this
-- when we are done (see Sem_Util.Requires_Transient_Scope).
-- 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.a Force Target_Strict_Alignment to True, even on targets where it
-- would normally be false. Can be used for testing strict alignment
-- circuitry in the compiler.
-- d.b Dump back end types. During Create_Standard, the back end is
-- queried for all available types. This option shows them.
-- 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.d Disable atomic synchronization for all atomic variable references.
-- Pragma Enable_Atomic_Synchronization is ignored.
-- d.e Enable atomic synchronization for all atomic variable references.
-- Pragma Disable_Atomic_Synchronization is ignored, and also the
-- compiler switch -gnated is ignored.
-- 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.h Minimize the creation of public internal symbols for concatenation
-- by enforcing a secondary stack-like handling of the final result.
-- The target of the concatenation is thus constrained in place and
-- initialized with the result instead of acting as its alias.
-- d.i Ignore all occurrences of pragma Warnings in the sources. This can
-- be used in particular to disable Warnings (Off) to check if any of
-- these statements are inappropriate.
-- d.k If an error message contains a reference to a location in an
-- internal unit, then suppress the line number in this reference.
-- d.j Generate listing of frontend inlined calls and inline calls passed
-- to the backend. This is useful to locate skipped calls that must be
-- inlined by the frontend.
-- 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 Ada 2005 and later.
-- 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.n Print source file names as they are loaded. This is useful if the
-- compiler has a bug -- these are the files that need to be included
-- in a bug report.
-- d.o Conservative elaboration order for indirect calls. This causes
-- P'Access to be treated as a call in more cases.
-- d.p In Ada 95 (or 83) mode, use original Ada 95 behavior for the
-- interpretation of component clauses crossing byte boundaries when
-- using the non-default bit order (i.e. ignore AI95-0133).
-- d.q If an array variable or constant is not modified in Ada code, and
-- is passed to an 'in' parameter of a foreign-convention subprogram,
-- and that subprogram modifies the array, the Ada compiler normally
-- assumes that the array is not modified. This option suppresses such
-- optimizations. This option should not be used; the correct solution
-- is to declare the parameter 'in out'.
-- d.r Do not reorder components in record types.
-- d.s The compiler no longer attempts to optimize the calls to secondary
-- stack management routines SS_Mark and SS_Release. As a result, each
-- transient block tasked with secondary stack management will fulfill
-- its role unconditionally.
-- d.s The compiler does not generate calls to secondary stack management
-- routines SS_Mark and SS_Release for a transient block when there is
-- an enclosing scoping construct which already manages the secondary
-- stack.
-- 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.u Sets Modify_Tree_For_C mode in which tree is modified to make it
-- easier to generate code using a C compiler.
-- d.v This flag enforces the elaboration rules defined in the SPARK
-- Reference Manual, chapter 7.7, to all SPARK code within a unit. As
-- a result, constructs which violate the rules in chapter 7.7 are no
-- longer accepted, even if the implementation is able to statically
-- ensure that accepting these constructs does not introduce the
-- possibility of failing an elaboration check.
-- d.w This flag turns off the scanning of 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.y Disable implicit pragma Elaborate_All on task bodies. When a task
-- body calls a procedure in the same package, and that procedure
-- calls a procedure in another package, the static elaboration
-- machinery adds an implicit Elaborate_All on the other package. This
-- switch disables the addition of the implicit pragma in such cases.
-- d.z Restore previous front-end support for Inline_Always. In default
-- mode, for targets that use the GCC back end, Inline_Always is
-- handled by the back end. Use of this switch restores the previous
-- handling of Inline_Always by the front end on such targets. For the
-- targets that do not use the GCC back end, this switch is ignored.
-- d.B Generate a bug box when we see an abort_statement, even though
-- there is no bug. Useful for testing Comperr.Compiler_Abort: write
-- some code containing an abort_statement, and compile it with
-- -gnatd.B. There is nothing special about abort_statements; it just
-- provides a way to control where the bug box is generated. See "when
-- N_Abort_Statement" in package body Expander.
-- d.C Generate call to System.Concat_n.Str_Concat_n routines in cases
-- where we would normally generate inline concatenation code.
-- d.D For compatibility with some Ada 95 compilers implementing only
-- one feature of Ada 2005 (overriding keyword), disable errors on use
-- of overriding keyword in Ada 95 mode.
-- d.E Turn selected errors into warnings. This debug switch causes a
-- specific set of error messages into warnings. Setting this switch
-- causes Opt.Error_To_Warning to be set to True. The intention is
-- that this be used for messages representing upwards incompatible
-- changes to Ada 2012 that cause previously correct programs to be
-- treated as illegal now. The following cases are affected:
--
-- Errors relating to overlapping subprogram parameters for cases
-- other than IN OUT parameters to functions.
--
-- Errors relating to the new rules about not defining equality
-- too late so that composition of equality can be assured.
--
-- Errors relating to overriding indicators on protected subprogram
-- bodies (not an Ada 2012 incompatibility, but might cause errors
-- for existing programs assuming they were legal because GNAT
-- formerly allowed them).
-- d.F Sets GNATprove_Mode to True. This allows debugging the frontend in
-- the special mode used by GNATprove.
-- d.G Previously the compiler ignored calls via generic formal parameters
-- when doing the analysis for the static elaboration model. This is
-- now fixed, but we provide this debug flag to revert to the previous
-- situation of ignoring such calls to aid in transition.
-- d.I Do not ignore enum representation clauses in CodePeer mode.
-- The default of ignoring representation clauses for enumeration
-- types in CodePeer is good for the majority of Ada code, but in some
-- cases being able to change this default might be useful to remove
-- some false positives.
-- d.J Relaxed rules for pragma No_Return. A pragma No_Return is illegal
-- if it applies to a body. This switch disables the legality check
-- for that. If the procedure does in fact return normally, execution
-- is erroneous, and therefore unpredictable.
-- d.K Do not reject components in extensions overlapping with the parent
-- component. Such components can be specified by means of a component
-- clause but they cannot be fully supported by the GCC type system.
-- This switch nevertheless allows them for the sake of compatibility.
-- d.L Normally the front end generates special expansion for conditional
-- expressions of a limited type. This debug flag removes this special
-- case expansion, leaving it up to the back end to handle conditional
-- expressions correctly.
-- d.M Relaxed RM semantics. This flag sets Opt.Relaxed_RM_Semantics
-- See Opt.Relaxed_RM_Semantics for more details.
-- d.N Enlarge entities by one node (but don't attempt to use this extra
-- node for storage of any flags or fields). This can be used to do
-- experiments on the impact of increasing entity sizes.
-- d.O Dump internal SCO tables. Before outputting the SCO information to
-- the ALI file, the internal SCO tables (SCO_Table/SCO_Unit_Table)
-- are dumped for debugging purposes.
-- d.P Previous non-optimized handling of length comparisons. Setting this
-- flag inhibits the effect of Optimize_Length_Comparison in Exp_Ch4.
-- This is there in case we find a situation where the optimization
-- malfunctions, to provide a work around.
-- d.Q Previous incomplete style checks for binary operators. Style checks
-- for token separation rules were incomplete and have been made
-- compliant with the documentation. For example, no warning was
-- issued for expressions such as 16-One or "A"&"B". Setting this flag
-- inhibits these new checks.
-- d.R As documented in lib-writ.ads, restrictions in the ali file can
-- have two forms, positional and named. The named notation is the
-- current preferred form, but the use of this debug switch will force
-- the use of the obsolescent positional form.
-- d.S Force Optimize_Alignment (Space) mode as the default
-- d.T Force Optimize_Alignment (Time) mode as the default
-- d.U Ignore indirect calls for static elaboration. The static
-- elaboration model is conservative, especially regarding indirect
-- calls. If you say Proc'Access, it will assume you might call
-- Proc. This can cause elaboration cycles at bind time. This flag
-- reverts to the behavior of earlier compilers, which ignored
-- indirect calls.
-- d.V Do not verify the validity of SCIL files (CodePeer mode). When
-- generating SCIL files for CodePeer, by default we verify that the
-- SCIL is well formed before saving it on disk. This switch can be
-- used to disable this checking, either to improve speed or to shut
-- down a false positive detected during the verification.
-- d.W Print out debugging information for Walk_Library_Items, including
-- the order in which units are walked. This is primarily for use in
-- debugging CodePeer mode.
-- d.X A previous version of GNAT allowed indexing aspects to be redefined
-- on derived container types, while the default iterator was
-- inherited from the parent type. This nonstandard extension is
-- preserved temporarily for use by the modeling project under debug
-- flag d.X.
-- d.Z Normally we always enable expansion in configurable run-time mode
-- to make sure we get error messages about unsupported features even
-- when compiling in -gnatc mode. But expansion is turned off in this
-- case if debug flag -gnatd.Z is used. This is to deal with the case
-- where we discover difficulties in this new processing.
-- d_a The compiler stops the examination of a task body once it reaches
-- an accept or select statement for the static elaboration model. The
-- behavior is similar to that of No_Entry_Calls_In_Elaboration_Code,
-- but does not penalize actual entry calls in elaboration code.
-- d_e The compiler ignores simple entry calls, asynchronous transfer of
-- control, conditional entry calls, timed entry calls, and requeue
-- statements in both the static and dynamic elaboration models.
-- d_f Issue info messages related to GNATprove usage to help users
-- understand analysis results. By default these are not issued as
-- beginners find them confusing. Set automatically by GNATprove when
-- switch --info is used.
-- d_i The compiler ignores calls and task activations when they target a
-- subprogram or task type defined in an external instance for both
-- the static and dynamic elaboration models.
-- d_j The compiler reads JSON files that would be generated by the same
-- compilation session if -gnatRjs was passed, in order to populate
-- the internal tables of the Repinfo unit from them.
-- d_p The compiler ignores calls to subprograms which verify the run-time
-- semantics of invariants and postconditions in both the static and
-- dynamic elaboration models.
-- d_s The compiler stops the examination of a task body once it reaches
-- a call to routine Ada.Synchronous_Task_Control.Suspend_Until_True
-- or Ada.Synchronous_Barriers.Wait_For_Release.
-- d_z Enable the default Put_Image on tagged types that are not
-- predefined.
-- d_A Do not generate ALI files by setting Opt.Disable_ALI_File.
-- d_B Warn on build-in-place function calls. This allows users to
-- inspect their code in case it triggers compiler bugs related
-- to build-in-place calls. See known-problem entries for details.
-- d_F The compiler encodes the full path from an invocation construct to
-- an external target, offering additional information to GNATBIND for
-- purposes of error diagnostics.
-- d_K (Reserved) Enable reporting a warning on known-problem issues of
-- previous releases. No action performed in the wavefront.
-- d_L 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
-- elaboration calls at compile time.
-- d_T The compiler outputs trace information to standard output whenever
-- an invocation path is recorded.
-- d_V Enable verification of the expanded code before calling the backend
-- and generate error messages on each inconsistency found.
-- 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.
-- Finally, this flag is also used for strict legality check, in
-- particular it will generate an error instead a warning when
-- encountering an unknown pragma.
-- 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 and the time of the compilation. This debug flag can
-- be used to suppress this output, and also suppresses the message
-- with the version of the compiler. This is useful for regression
-- tests which need to have consistent output.
-- 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.
-- d9 This allows lock free implementation for protected objects
-- (see Exp_Ch9).
-- d.1 Sets Opt.Unnest_Subprogram_Mode to enable unnesting of subprograms.
-- This special pass does not actually unnest things, but it ensures
-- that a nested procedure does not contain any uplevel references.
-- See spec of Exp_Unst for full details.
-- d.2 Allow statements within declarative parts. This is not usually
-- allowed, but in some debugging contexts (e.g. testing the circuit
-- for unnesting of procedures), it is useful to allow this.
-- d.3 Output debugging information from Exp_Unst, including the name of
-- any unreachable subprograms that get deleted.
-- d.4 By default in case of an error during C generation, the .c or .h
-- file is deleted. This flag keeps the C file.
-- d.5 By default a subprogram imported generates a subprogram profile.
-- This debug flag disables this generation when generating C code,
-- assuming a proper #include will be used instead.
-- d.6 By default the C back-end avoids declaring types that are not
-- referenced by the generated C code. This debug flag restores the
-- output of all the types.
-- d.7 Indicates (to gnat2scil) that CodePeer is being invoked as a
-- prover by the SPARK tools and that therefore gnat2scil should
-- avoid SCIL generation strategies which can introduce soundness
-- issues (e.g., assuming that a low bound of an array parameter
-- of an unconstrained subtype belongs to the index subtype).
-- d.9 Enable build-in-place for function calls returning some nonlimited
-- types.
------------------------------------------
-- 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.
-- db Output debug information from Better_Choice in Binde, which uses
-- various heuristics to determine elaboration order in cases where
-- multiple orders are valid.
-- 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 older 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. Note: -do is even older
-- than -dp.
-- dp Use old elaboration order preference. The new preference rules
-- elaborate all units within a strongly connected component together,
-- with no other units in between. In particular, if a spec/body pair
-- can be elaborated together, it will be. In the new order, the binder
-- behaves as if every pragma Elaborate_All that would be legal is
-- present, even if it does not appear in the source code.
-- du List unit name and file name for each unit as it is read in
-- dv Verbose debugging printouts
-- dx Force the binder to read (and then ignore) the xref information
-- in ali files (used to check that read circuit is working OK).
-- d_a GNATBIND ignores the effects of pragma Elaborate_All in the case of
-- elaboration order and treats the associated dependency as a regular
-- with edge.
-- d_b GNATBIND ignores the effects of pragma Elaborate_Body in the case
-- of elaboration order and treats the spec and body as decoupled.
-- d_e GNATBIND ignores the effects of pragma Elaborate in the case of
-- elaboration order and no longer creates an implicit dependency on
-- the body of the argument.
-- d_t GNATBIND output trace information of cycle-detection activities to
-- standard output.
-- d_A GNATBIND output the contents of all ALI invocation-related tables
-- in textual format to standard output.
-- d_C GNATBIND diagnoses all unique cycles within the bind, rather than
-- just the most important one.
-- d_I GNATBIND outputs the contents of the invocation graph in textual
-- format to standard output.
-- d_L GNATBIND outputs the contents of the library graph in textual
-- format to standard output.
-- d_P GNATBIND outputs the cycle paths to standard output
-- d_S GNATBIND outputs trace information concerning the status of its
-- various phases to standard output.
-- d_T GNATBIND outputs trace information of elaboration order detection
-- activities to standard output.
-- d_V GNATBIND validates the invocation graph, library graph along with
-- its cycles, and the elaboration order.
