- -- dm Some features are permitted only in OpenVMS ports of GNAT (e.g.

- -- 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.
+ -- trace through elaboration calls at compile time.
-- dM Assume all variables have been modified, and ignore current value
-- indications. This debug flag disconnects the tracking of constant
-- in preelaborable packages, but this restriction is a huge pain,
-- especially in the predefined library units.
- -- dQ Eliminate check for duplicate external tags. This check was added
- -- as per AI 0113, and causes some backward compatibility problems.
- -- It is never legitimate to have duplicate external tags, so the
- -- check is certainly valid, but this debug switch can be useful for
- -- enabling previous behavior of ignoring this problem.
+ -- 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
-- 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.
-- 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 -gnat05 mode.
-- compiler has a bug -- these are the files that need to be included
-- in a bug report.
- -- d.o Generate listing showing the IL instructions generated by the .NET
- -- compiler for each subprogram.
-
- -- d.p Enable the .NET CIL verifier. During development the verifier is
- -- disabled by default and this flag is used to enable it. In the
- -- future we will reverse this functionality.
+ -- d.o Conservative elaboration order for indirect calls. This causes
+ -- P'Access to be treated as a call in more cases.
-- 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.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 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 loops to detect possible
-- infinite loops.
- -- d.A There seems to be a problem with ASIS if we activate the circuit
- -- for reading and writing the aspect specification hash table, so
- -- for now, this is controlled by the debug flag d.A. The hash table
- -- is only written and read if this flag is set.
-
-- 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.D Strict Alfa mode. Interpret compiler permissions as strictly as
- -- possible in Alfa mode.
-
- -- d.E Force Alfa mode for gnat2why. In this mode, errors are issued for
- -- all violations of Alfa in user code, and warnings are issued for
- -- constructs not yet implemented in gnat2why.
+ -- 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.F Alfa mode. Generate AST in a form suitable for formal verification,
- -- as well as additional cross reference information in ALI files to
- -- compute effects of subprograms.
-
- -- d.G Precondition only mode for gnat2why. In this mode, gnat2why will
- -- only generate Why code that checks for the well-guardedness of
- -- preconditions.
+ -- d.A There seems to be a problem with ASIS if we activate the circuit
+ -- for reading and writing the aspect specification hash table, so
+ -- for now, this is controlled by the debug flag d.A. The hash table
+ -- is only written and read if this flag is set.
- -- d.H Standard package only mode for gnat2why. In this mode, gnat2why
- -- will only generate Why code for package Standard. Any given input
- -- file will be 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.I Generate SCIL mode. Generate intermediate code for the sake of
- -- of static analysis tools, and ensure additional tree consistency
- -- between different compilations of specs.
+ -- d.C Generate call to System.Concat_n.Str_Concat_n routines in cases
+ -- where we would normally generate inline concatenation code.
- -- d.J Disable parallel SCIL generation. Normally SCIL file generation is
- -- done in parallel to speed processing. This switch disables this
- -- behavior.
+ -- 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.K Alfa detection only mode for gnat2why. In this mode, gnat2why
- -- will only generate the .alfa file, but no Why code.
+ -- 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.H Sets ASIS_GNSA_Mode to True. This signals the front end to suppress
+ -- the call to gigi in ASIS_Mode.
+
+ -- 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.K Enable generation of contract-only procedures in CodePeer mode and
+ -- report a warning on subprograms for which the contract-only body
+ -- cannot be built. Currently reported on subprograms defined in
+ -- nested package specs that have some formal (or return type) whose
+ -- type is a private type defined in some enclosing package and that
+ -- have pre/postconditions.
-- 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.
-- 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 By default, the compiler uses an elaborate rewriting framework for
- -- short-circuited forms where the right hand condition generates
- -- actions to be inserted. With the gcc backend, we now use the new
- -- N_Expression_With_Actions node for this expansion, but we still use
- -- the old method for other backends and in SCIL mode. This debug flag
- -- forces use of the new N_Expression_With_Actions node in these other
- -- cases and is intended for transitional use.
+ -- 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.Y Prevents the use of the N_Expression_With_Actions node even in the
- -- case of the gcc back end. Provided as a back up in case the new
- -- scheme has problems.
+ -- 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.
-- d1 Error messages have node numbers where possible. Normally error
-- messages have only source locations. This option is useful when
-- 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.
+ -- 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.
