24 ------------------------------------------------------------------------------
26 -- This package contains, for each of the command of the GNAT driver, one
27 -- constant array; each component of this array is a string that defines,
28 -- in coded form as explained below, the conversion of a VMS qualifier of the
29 -- command to the corresponding switch of the GNAT tool corresponding to the
30 -- command.
32 -- This package is used by the GNAT driver to invokes the GNAT tools with the
33 -- switches corresponding to the VMS qualifier and by the Project Manager to
34 -- convert VMS qualifiers in project files to their corresponding switch
35 -- values.
37 -- This package is also an input to the tool that generates the VMS GNAT
38 -- help information automatically.
40 -- NOTE: the format of this package must follow the following rules, so that
41 -- the VMS GNAT help tool works properly:
43 -- - Each command zone (where the eventual qualifiers are declared) must
44 -- begin with a boxed comment of the form:
46 -- ---------------------------------
47 -- -- Switches for GNAT <COMMAND> --
48 -- ---------------------------------
50 -- where <COMMAND> is the name of a GNAT command in capital letters, for
51 -- example BIND, COMPILE, XREF, ...
53 -- - each qualifier declaration must be followed either by
54 -- - a comment starting with "-- NODOC", to indicate that there is
55 -- no documentation for this qualifier, or
56 -- - a contiguous sequence of comments that constitute the
57 -- documentation of the qualifier.
59 -- - each command zone ends with the declaration of the constant array
60 -- for the command, of the form:
62 -- <Command>__Switches : aliased constant Switches :=
66 ----------------
67 -- QUALIFIERS --
68 ----------------
70 -- The syntax of a qualifier declaration is as follows:
72 -- SWITCH_STRING ::= "/ command-qualifier-name TRANSLATION"
74 -- TRANSLATION ::=
75 -- DIRECT_TRANSLATION
76 -- | DIRECTORIES_TRANSLATION
77 -- | FILE_TRANSLATION
78 -- | NO_SPACE_FILE_TRANSL
79 -- | NUMERIC_TRANSLATION
80 -- | STRING_TRANSLATION
81 -- | OPTIONS_TRANSLATION
82 -- | COMMANDS_TRANSLATION
83 -- | ALPHANUMPLUS_TRANSLATION
84 -- | OTHER_TRANSLATION
86 -- DIRECT_TRANSLATION ::= space UNIX_SWITCHES
87 -- DIRECTORIES_TRANSLATION ::= =* UNIX_SWITCH *
88 -- DIRECTORY_TRANSLATION ::= =% UNIX_SWITCH %
89 -- FILE_TRANSLATION ::= =@ UNIX_SWITCH @
90 -- NO_SPACE_FILE_TRANSL ::= =< UNIX_SWITCH >
91 -- NUMERIC_TRANSLATION ::= =# UNIX_SWITCH # | # number #
92 -- STRING_TRANSLATION ::= =" UNIX_SWITCH "
93 -- OPTIONS_TRANSLATION ::= =OPTION {space OPTION}
94 -- COMMANDS_TRANSLATION ::= =? ARGS space command-name
95 -- ALPHANUMPLUS_TRANSLATION ::= =| UNIX_SWITCH |
97 -- UNIX_SWITCHES ::= UNIX_SWITCH {, UNIX_SWITCH}
99 -- UNIX_SWITCH ::= unix-switch-string | !unix-switch-string | `string'
101 -- OPTION ::= option-name space UNIX_SWITCHES
103 -- ARGS ::= -cargs | -bargs | -largs
105 -- Here command-qual is the name of the switch recognized by the GNATCmd.
106 -- This is always given in upper case in the templates, although in the
107 -- actual commands, either upper or lower case is allowed.
109 -- The unix-switch-string always starts with a minus, and has no commas
110 -- or spaces in it. Case is significant in the unix switch string. If a
111 -- unix switch string is preceded by the not sign (!) it means that the
112 -- effect of the corresponding command qualifier is to remove any previous
113 -- occurrence of the given switch in the command line.
115 -- The DIRECTORIES_TRANSLATION format is used where a list of directories
116 -- is given. This possible corresponding formats recognized by GNATCmd are
117 -- as shown by the following example for the case of PATH
119 -- PATH=direc
120 -- PATH=(direc,direc,direc,direc)
122 -- When more than one directory is present for the DIRECTORIES case, then
123 -- multiple instances of the corresponding unix switch are generated,
124 -- with the file name being substituted for the occurrence of *.
126 -- The FILE_TRANSLATION format is similar except that only a single
127 -- file is allowed, not a list of files, and only one unix switch is
128 -- generated as a result.
130 -- the NO_SPACE_FILE_TRANSL is similar to FILE_TRANSLATION, except that
131 -- no space is inserted between the switch and the file name.
133 -- The NUMERIC_TRANSLATION format is similar to the FILE_TRANSLATION case
134 -- except that the parameter is a decimal integer in the range 0 to 999999.
136 -- For the OPTIONS_TRANSLATION case, GNATCmd similarly permits one or
137 -- more options to appear (although only in some cases does the use of
138 -- multiple options make logical sense). For example, taking the
139 -- case of ERRORS for GCC, the following are all allowed:
141 -- /ERRORS=BRIEF
142 -- /ERRORS=(FULL,VERBOSE)
143 -- /ERRORS=(BRIEF IMMEDIATE)
145 -- If no option is provided (e.g. just /ERRORS is written), then the
146 -- first option in the list is the default option. For /ERRORS this
147 -- is NORMAL, so /ERRORS with no option is equivalent to /ERRORS=NORMAL.
149 -- The COMMANDS_TRANSLATION case is only used for gnatmake, to correspond
150 -- to the use of -cargs, -bargs and -largs (the ARGS string as indicated
151 -- is one of these three possibilities). The name given by COMMAND is the
152 -- corresponding command name to be used to interpret the switches to be
153 -- passed on. Switches of this type set modes, e.g. /COMPILER_QUALIFIERS
154 -- sets the mode so that all subsequent switches, up to another switch
155 -- with COMMANDS_TRANSLATION apply to the corresponding commands issued
156 -- by the make utility. For example
158 -- /COMPILER_QUALIFIERS /LIST /BINDER_QUALIFIERS /MAIN
159 -- /COMPILER_QUALIFIERS /NOLIST /COMPILE_CHECKS=SYNTAX
161 -- Clearly these switches must come at the end of the list of switches
162 -- since all subsequent switches apply to an issued command.
164 -- For the DIRECT_TRANSLATION case, an implicit additional qualifier
165 -- declaration is created by prepending NO to the name of the qualifier,
166 -- and then inverting the sense of the UNIX_SWITCHES string. For example,
167 -- given the qualifier definition:
169 -- "/LIST -gnatl"
171 -- An implicit qualifier definition is created:
173 -- "/NOLIST !-gnatl"
175 -- In the case where, a ! is already present, inverting the sense of the
176 -- switch means removing it.
179 -- A synonym to shorten the table
182 -- String pointer type used throughout
185 -- Type used for array of switches

443 -- elaborate pragmas.
447 -- /PROJECT_FILE=filename
448 --
449 -- Specifies the main project file to be used. The project files rooted
450 -- at the main project file will be parsed before the invocation of the
451 -- binder. The source and object directories to be searched will be

453 -- and ADA_PRJ_OBJECTS_FILE.
462 -- /READ_SOURCES[=(keyword[,...])]
463 -- /NOREAD_SOURCES
464 --
465 -- The following keyword are accepted:
466 --
467 -- ALL (D) Require source files to be present. In this mode, the
468 -- binder insists on being able to locate all source files
469 -- that are referenced and checks their consistency. In
470 -- normal mode, if a source file cannot be located it is
471 -- simply ignored. If you specify the ALL keyword, a
472 -- missing source file is an error.
473 --
474 -- NONE Exclude source files. In this mode, the binder only
475 -- checks that ALI files are consistent with one another.
476 -- source files are not accessed. The binder runs faster
477 -- in this mode, and there is still a guarantee that the
478 -- resulting program is self-consistent.
479 --
480 -- If a source file has been edited since it was last
481 -- compiled and you specify the NONE keyword, the binder
482 -- will not detect that the object file is out of date
483 -- with the source file.
484 --
485 -- This is the same as specifying /NOREAD_SOURCES.
486 --
487 -- AVAILABLE Check that object files are consistent with one
488 -- another and are consistent with any source files that
489 -- can be located.
493 -- NODOC (see /READ_SOURCES)
497 -- /RENAME_MAIN=xxx
498 --
499 -- Renames the generated main program from main to xxx.
500 -- This is useful in the case of some cross-building environments, where
501 -- the actual main program is separate from the one generated
502 -- by GNAT BIND.
511 -- /REPORT_ERRORS[=(keyword[,...])]
512 -- VERBOSE (D)
513 -- BRIEF
514 -- DEFAULT
515 -- /NOREPORT_ERRORS
516 --
517 -- With the DEFAULT keyword (which is not the default when the binder is
518 -- run from GNAT BIND) or the /NOREPORT_ERRORS qualifier, brief error
519 -- messages are generated to SYS$ERROR. If the VERBOSE keyword is
520 -- present, a header is written to SYS$OUTPUT and any error messages are
521 -- directed to SYS$OUTPUT All that is written to SYS$ERROR is a brief
522 -- summary message.
523 --
524 -- If the BRIEF keyword is specified, the binder will generate brief error
525 -- messages to SYS$ERROR even if verbose mode is specified. This is
526 -- relevant only when used together with the VERBOSE keyword or /VERBOSE
527 -- qualifier.
531 -- NODOC (see /REPORT_ERRORS)
535 -- /NORESTRICTION_LIST (D)
536 -- /RESTRICTION_LIST
537 --
538 -- Generate list of pragma Restrictions that could be applied to the
539 -- current unit. This is useful for code audit purposes, and also may be
540 -- used to improve code generation in some cases.
547 -- /RETURN_CODES=POSIX (D)
548 -- /RETURN_CODES=VMS
549 --
550 -- Specifies the style of default exit code returned. Must be used in
551 -- conjunction with and match the Link qualifier with same name.
552 --
553 -- POSIX (D) Return Posix success (0) by default.
554 --
555 -- VMS Return VMS success (1) by default.
559 -- /RUNTIME_SYSTEM=xxx
560 --
561 -- Binds against an alternate runtime system named xxx or RTS-xxx.
565 -- /SEARCH=(directory[,...])
566 --
567 -- When looking for source or object files also look in directories
568 -- specified.
569 --
570 -- This is the same as specifying both /LIBRARY_SEARCH and /SOURCE_SEARCH
571 -- for a directory.
575 -- /SHARED
576 -- /NOSHARED
577 --
578 -- Link against a shared GNAT run time when available.
582 -- /TIME_SLICE=nnn
583 --
584 -- Set the time slice value to nnn milliseconds. A value of zero means no
585 -- time slicing and also indicates to the tasking run time to match as
586 -- close as possible to the annex D requirements of the RM.
590 -- /SOURCE_SEARCH=(directory[,...])
591 --
592 -- When looking for source files also look in directories specified.
596 -- /STATIC
597 -- /NOSTATIC
598 --
599 -- Link against a static GNAT run time.
603 -- /STORE_TRACEBACKS (D)
604 -- /NOSTORE_TRACEBACKS
605 --
606 -- Store tracebacks in exception occurrences.
607 -- This is the default on VMS, with the zero-cost exception mechanism.
608 -- This qualifier has no impact, except when using the setjmp/longjmp
609 -- exception mechanism, with the GNAT COMPILE qualifier /LONGJMP_SETJMP.
613 -- /SUBDIRS=dir
614 --
615 -- The actual directories (object, exec, library, ...) are subdirectories
616 -- of the directory specified in the project file. If the subdirectory
617 -- does not exist, it is created automatically.
621 -- /TIME_STAMP_CHECK (D)
622 --
623 -- Time stamp errors will be treated as errors.
624 --
625 -- /NOTIME_STAMP_CHECK
626 --
627 -- Ignore time stamp errors. Any time stamp error messages are treated as
628 -- warning messages. This switch essentially disconnects the normal
629 -- consistency checking, and the resulting program may have undefined
630 -- semantics if inconsistent units are present.
631 --
632 -- This means that /NOTIME_STAMP_CHECK should be used only in unusual
633 -- situations, with extreme care.
637 -- /VERBOSE (D)
638 -- /NOVERBOSE
639 --
640 -- Equivalent to /REPORT_ERRORS=VERBOSE.
649 -- /WARNINGS[=(keyword[,...])]
650 -- /NOWARNINGS
651 --
652 -- The following keywords are supported:
653 --
654 -- NORMAL (D) Print warning messages and treat them as warning.
655 -- SUPPRESS Suppress all warning messages (same as /NOWARNINGS).
656 -- ERROR Treat any warning messages as fatal errors
660 -- NODOC (see /WARNINGS)
675 -- /NOWIDE_CHARACTER_ENCODING (D)
676 -- /WIDE_CHARACTER_ENCODING[=encode-type]
677 --
678 -- Specifies the mechanism used to encode wide characters, overriding
679 -- the default as set by the /WIDE_CHARACTER_ENCODING option for the
680 -- compilation of the main program.
684 -- /NOZERO_MAIN (D)
685 -- /ZERO_MAIN
686 --
687 -- Normally the binder checks that the unit name given on the command line
688 -- corresponds to a suitable main subprogram. When /ZERO_MAIN is used,
689 -- a list of ALI files can be given, and the execution of the program
690 -- consists of elaboration of these units in an appropriate order.

1217 -------------------------------
1221 -- /NO83 (D)
1222 -- /83
1223 --
1224 -- Although GNAT is primarily an Ada 95 compiler, it accepts this
1225 -- qualifier to specify that an Ada 83 mode program is being compiled. If
1226 -- you specify this qualifier, GNAT rejects Ada 95 extensions and applies
1227 -- Ada 83 semantics. It is not possible to guarantee this qualifier does
1228 -- a perfect job; for example, some subtle tests of pathological cases,
1229 -- such as are found in ACVC tests that have been removed from the ACVC
1230 -- suite for Ada 95, may not compile correctly. However for practical
1231 -- purposes, using this qualifier should ensure that programs that
1232 -- compile correctly under the /83 qualifier can be ported reasonably
1233 -- easily to an Ada 83 compiler. This is the main use of this qualifier.
1234 --
1235 -- With few exceptions (most notably the need to use "<>" on
1236 -- unconstrained generic formal parameters), it is not necessary to use
1237 -- this qualifier switch when compiling Ada 83 programs, because, with
1238 -- rare and obscure exceptions, Ada 95 is upwardly compatible with Ada
1239 -- 83. This means that a correct Ada 83 program is usually also a correct
1240 -- Ada 95 program.
1244 -- /95 (D)
1245 --
1246 -- Allows GNAT to recognize the full range of Ada 95 constructs.
1247 -- This is the normal default for GNAT Pro.
1251 -- /05 (D)
1252 --
1253 -- Allows GNAT to recognize the full range of Ada 2005 constructs.
1257 -- /05 (D)
1258 --
1259 -- Allows GNAT to recognize the full range of Ada 2005 constructs.
1260 -- Equivalent to /05 (/2005 is the preferred usage).
1264 -- /05 (D)
1265 --
1266 -- Allows GNAT to recognize all implemented proposed Ada 2012
1267 -- extensions. See features file for list of implemented features.
1271 -- /05 (D)
1272 --
1273 -- Allows GNAT to recognize all implemented proposed Ada 2012
1274 -- extensions. See features file for list of implemented features.
1275 -- Equivalent to /12 (/2012 is the preferred usage).
1279 -- /ADD_PROJECT_SEARCH_PATH=(directory[,...])
1280 --
1281 -- Add directories to the project search path.
1285 -- /NOASM (D)
1286 -- /ASM
1287 --
1288 -- Use to cause the assembler source file to be generated, using S as the
1289 -- filetype, instead of the object file. This may be useful if you need
1290 -- to examine the generated assembly code.
1294 -- /NO_ASSUME_VALID (D)
1295 -- /ASSUME_VALID
1296 --
1297 -- Use to tell the compiler to assume that all objects have valid values
1298 -- except those occurring as prefixes to 'Valid attributes. In the default
1299 -- mode, the compiler assumes that values may be invalid unless it can
1300 -- be sure that they are valid, and code is generated to allow for this
1301 -- possibility. The use of /ASSUME_VALID will improve the code.
1305 -- /NO_CATEGORIZATION_WARNINGS (D)
1306 -- /CATEGORIZATION_WARNINGS
1307 --
1308 -- Use to tell the compiler to disable categorization dependency errors.
1309 -- Ada requires that units that WITH one another have compatible
1310 -- categories, for example a Pure unit cannot WITH a Preelaborate unit.
1311 -- If this switch is used, these errors become warnings (which can be
1312 -- ignored, or suppressed in the usual manner). This can be useful in
1313 -- some specialized circumstances such as the temporary use of special
1314 -- test software.
1333 -- /NOCHECKS
1334 -- /CHECKS[=(keyword[,...])]
1335 --
1336 -- If you compile with the default options, GNAT will insert many runtime
1337 -- checks into the compiled code, including code that performs range
1338 -- checking against constraints, but not arithmetic overflow checking for
1339 -- integer operations (including division by zero) or checks for access
1340 -- before elaboration on subprogram calls. All other runtime checks, as
1341 -- required by the Ada 95 Reference Manual, are generated by default.
1342 --
1343 -- You may specify one or more of the following keywords to the /CHECKS
1344 -- qualifier to modify this behavior:
1345 --
1346 -- DEFAULT The behavior described above. This is the default
1347 -- if the /CHECKS qualifier is not present on the
1348 -- command line. Same as /NOCHECKS.
1349 --
1350 -- OVERFLOW Enables overflow checking in CHECKED mode for integer
1351 -- operations and checks for access before elaboration
1352 -- on subprogram calls. This causes GNAT to generate
1353 -- slower and larger executable programs by adding code
1354 -- to check for both overflow and division by zero
1355 -- (resulting in raising "Constraint_Error" as required
1356 -- by Ada semantics).
1357 -- Similarly, GNAT does not generate elaboration check
1358 -- by default, and you must specify this keyword to
1359 -- enable them.
1360 --
1361 -- Note that this keyword does not affect the code
1362 -- generated for any floating-point operations; it
1363 -- applies only to integer operations. For the case of
1364 -- floating-point, GNAT has the "Machine_Overflows"
1365 -- attribute set to "False" and the normal mode of
1366 -- operation is to generate IEEE NaN and infinite values
1367 -- on overflow or invalid operations (such as dividing
1368 -- 0.0 by 0.0).
1369 --
1370 -- ELABORATION Enables dynamic checks for access-before-elaboration
1371 -- on subprogram calls and generic instantiations.
1372 --
1373 -- ASSERTIONS The pragmas "Assert" and "Debug" normally have no
1374 -- effect and are ignored. This keyword causes "Assert"
1375 -- and "Debug" pragmas to be activated, as well as
1376 -- "Check", "Precondition" and "Postcondition" pragmas.
1377 --
1378 -- SUPPRESS_ALL Suppress all runtime checks as though you have
1379 -- "pragma Suppress (all_checks)" in your source. Use
1380 -- this switch to improve the performance of the code at
1381 -- the expense of safety in the presence of invalid data
1382 -- or program bugs.
1383 --
1384 -- UNSUPPRESS_ALL Cancels effect of previous SUPPRESS_ALL.
1385 --
1386 -- DEFAULT Suppress the effect of any option OVERFLOW or
1387 -- ASSERTIONS.
1388 --
1389 -- FULL (D) Similar to OVERFLOW, but suppress the effect of any
1390 -- option ELABORATION or SUPPRESS_ALL.
1391 --
1392 -- These keywords only control the default setting of the checks. You
1393 -- may modify them using either "Suppress" (to remove checks) or
1394 -- "Unsuppress" (to add back suppressed checks) pragmas in your program
1395 -- source.
1399 -- NODOC (see /CHECKS)
1403 -- /NOCOMPRESS_NAMES (D)
1404 -- /COMPRESS_NAMES
1405 --
1406 -- Compress debug information and external symbol name table entries.
1407 -- In the generated debugging information, and also in the case of long
1408 -- external names, the compiler uses a compression mechanism if the name
1409 -- is very long. This compression method uses a checksum, and avoids
1410 -- trouble on some operating systems which have difficulty with very long
1411 -- names.
1415 -- /CONFIGURATION_PRAGMAS_FILE=file

1423 --
1424 -- Look for source files in the default directory.
1428 -- /DATA_PREPROCESSING=file_name
1429 --
1430 -- This qualifier indicates to the compiler the file name (without
1431 -- directory information) of the preprocessor data file to use.
1432 -- The preprocessor data file should be found in the source directories.
1433 --
1434 -- A preprocessing data file is a text file with significant lines
1435 -- indicating how should be preprocessed either a specific source or all
1436 -- sources not mentioned in other lines. A significant line is a non
1437 -- empty, non comment line. Comments are similar to Ada comments.
1438 --
1439 -- Each significant line starts with either a literal string or the
1440 -- character '*'. A literal string is the file name (without directory
1441 -- information) of the source to preprocess. A character '*' indicates the
1442 -- preprocessing for all the sources that are not specified explicitly on
1443 -- other lines. It is an error to have two lines with the same file name
1444 -- or two lines starting with the character '*'.
1445 --
1446 -- After the file name or the character '*', another optional literal
1447 -- string indicating the file name of the definition file to be used for
1448 -- preprocessing. (see 15.3 Form of Definitions File. The definition files
1449 -- are found by the compiler in one of the source directories. In some
1450 -- cases, when compiling a source in a directory other than the current
1451 -- directory, if the definition file is in the current directory, it may
1452 -- be necessary to add the current directory as a source directory through
1453 -- qualifier "/SEARCH=[]", otherwise the compiler would not find the
1454 -- definition file.
1455 --
1456 -- Then, optionally, switches similar to those of gnatprep may be found.
1457 -- Those switches are:
1458 --
1459 -- -b Causes both preprocessor lines and the lines deleted by
1460 -- preprocessing to be replaced by blank lines, preserving
1461 -- the line number. This switch is always implied;
1462 -- however, if specified after `-c' it cancels the effect
1463 -- of `-c'.
1464 --
1465 -- -c Causes both preprocessor lines and the lines deleted by
1466 -- preprocessing to be retained as comments marked with
1467 -- the special string "--! ".
1468 --
1469 -- -Dsymbol=value Define or redefine a symbol, associated with value.
1470 -- A symbol is an Ada identifier, or an Ada reserved word,
1471 -- with the exception of "if", "else", "elsif", "end",
1472 -- "and", "or" and "then". value is either a literal
1473 -- string, an Ada identifier or any Ada reserved word.
1474 -- A symbol declared with this switch replaces a symbol
1475 -- with the same name defined in a definition file.
1476 --
1477 -- -s Causes a sorted list of symbol names and values to be
1478 -- listed on the standard output file.

1480 -- -u Causes undefined symbols to be treated as having the
1481 -- value FALSE in the context of a preprocessor test.
1482 -- In the absence of this option, an undefined symbol

1801 -- /NOINLINE (D)
1802 -- /INLINE[=keyword]
1803 --
1804 -- Selects the level of inlining for your program. In the absence of this

1808 --
1809 -- The supported keywords are as follows:
1810 --
1811 -- PRAGMA (D) Recognize and process "Inline" pragmas. However,
1812 -- for the inlining to actually occur, optimization
1813 -- must be enabled. This enables inlining across unit
1814 -- boundaries, that is, inlining a call in one unit of
1815 -- a subprogram declared in a with'ed unit. The compiler
1816 -- will access these bodies, creating an extra source
1817 -- dependency for the resulting object file, and where
1818 -- possible, the call will be inlined.
1819 --
1820 -- This qualifier also turns on full optimization and
1821 -- requests GNAT to try to attempt automatic inlining
1822 -- of small subprograms within a unit.
1823 --
1824 -- Specifying /OPTIMIZE=NONE will disable the main effect

1905 -- /MAPPING_FILE=file_name
1906 --
1907 -- Use mapping file file_name
1908 --
1909 -- A mapping file is a way to communicate to the compiler two mappings:
1910 -- from unit names to file names (without any directory information) and
1911 -- from file names to path names (with full directory information).
1912 -- These mappings are used by the compiler to short-circuit the path
1913 -- search.
1914 --
1915 -- The use of mapping files is not required for correct operation of the
1916 -- compiler, but mapping files can improve efficiency, particularly when
1917 -- sources are read over a slow network connection. In normal operation,
1918 -- you need not be concerned with the format or use of mapping files,
1919 -- and /MAPPING_FILE is not a qualifier that you would use explicitly.
1920 -- It is intended only for use by automatic tools such as GNAT MAKE
1921 -- running under the project file facility. The description here of the
1922 -- format of mapping files is provided for completeness and for possible
1923 -- use by other tools.
1924 --
1925 -- A mapping file is a sequence of sets of three lines. In each set, the
1926 -- first line is the unit name, in lower case, with "%s" appended for
1927 -- specifications and "%b" appended for bodies; the second line is the
1928 -- file name; and the third line is the path name.
1929 --
1930 -- Example:
1931 --
1932 -- main%b
1933 -- main.2_ada
1934 -- /gnat/project1/sources/main.2_ada
1935 --
1936 -- When qualifier ?MAPPING_FILE is specified, the compiler will create in
1937 -- memory the two mappings from the specified file. If there is any
1938 -- problem (non existent file, truncated file or duplicate entries),
1939 -- no mapping will be created.
1940 --
1941 -- Several /MAPPING_FILE qualifiers may be specified; however, only the
1942 -- last one on the command line will be taken into account.
1943 --
1944 -- When using a project file, GNAT MAKE creates a temporary mapping file
1945 -- and communicates it to the compiler using this switch.
1950 -- /MAX_INSTANTIATIONS=nnn
1951 --
1952 -- Specify the maximum number of instantiations permitted. The default
1953 -- value is 8000, which is probably enough for all programs except those
1954 -- containing some kind of runaway unintended instantiation loop.
1963 -- /MESSAGES_PROJECT_FILE[=messages-option]
1964 --
1965 -- Specifies the "verbosity" of the parsing of project files.
1966 -- messages-option may be one of the following:
1967 --
1968 -- DEFAULT (D) No messages are output if there is no error or warning.
1969 --
1970 -- MEDIUM A small number of messages are output.
1971 --
1972 -- HIGH A great number of messages are output, most of them not
1973 -- being useful for the user.
1977 -- /MULTI_UNIT_INDEX=nnn
1978 --
1979 -- Specify the index of the unit to compile in a multi-unit source file.
1983 -- /MAX_NESTING=nnn
1984 --
1985 -- Set maximum level of nesting of constructs (including subprograms,
1986 -- loops, blocks, packages, and conditionals).
1987 -- The level of nesting must not exceed the given value nnn.
1988 -- A value of zero disable this style check (not enabled by default).
1992 -- /NO_GNAT_ADC
1993 --
1994 -- Cause the compiler to ignore any configuration pragmas file GNAT.ADC
1995 -- in the default directory. Implied by qualifier /PROJECT_FILE.
1996 -- Often used in conjunction with qualifier /CONFIGURATION_PRAGMAS_FILE.
2000 -- /NOLOAD
2001 --
2002 -- Cause the compiler to operate in semantic check mode with full
2003 -- checking for all illegalities specified in the reference manual, but
2004 -- without generation of any source code (no object or ALI file
2005 -- generated).
2006 --
2007 -- Since dependent files must be accessed, you must follow the GNAT
2008 -- semantic restrictions on file structuring to operate in this mode:
2009 --
2010 -- o The needed source files must be accessible.
2011 -- o Each file must contain only one compilation unit.
2012 -- o The file name and unit name must match.
2013 --
2014 -- The output consists of error messages as appropriate. No object file
2015 -- or ALI file is generated. The checking corresponds exactly to the
2016 -- notion of legality in the Ada reference manual.
2017 --
2018 -- Any unit can be compiled in semantics-checking-only mode, including
2019 -- units that would not normally be compiled (generic library units,
2020 -- subunits, and specifications where a separate body is present).

2026 -- Do not look in the default directory for source files of the runtime.
2030 -- /NOSTD_LIBRARIES

2036 -- /NOWARNING_PRAGMAS
2037 --
2038 -- Causes all Warnings pragmas to be ignored. Useful to check if the
2039 -- program has obsolete warnings pragmas that are hiding problems.
2058 -- /NOOPTIMIZE (D)
2059 -- /OPTIMIZE[=(keyword[,...])]
2060 --
2061 -- Selects the level of optimization for your program. The supported
2062 -- keywords are as follows:
2063 --
2064 -- ALL (D) Perform most optimizations, including those that
2065 -- may be expensive.
2066 --
2067 -- NONE Do not do any optimizations. Same as /NOOPTIMIZE.

2074 -- DEVELOPMENT Same as SOME.
2075 --
2076 -- INLINING Full optimization, and also attempt automatic inlining
2077 -- of small subprograms within a unit
2078 --
2079 -- UNROLL_LOOPS Try to unroll loops. This keyword may be specified
2080 -- with any keyword above other than NONE. Loop
2081 -- unrolling usually, but not always, improves the
2082 -- performance of programs.
2083 --
2084 -- NO_STRICT_ALIASING
2085 -- Suppress aliasing analysis. When optimization is
2086 -- enabled (ALL or SOME above), the compiler assumes
2087 -- that pointers do in fact point to legitimate values
2088 -- of the pointer type (allocated from the proper pool).
2089 -- If this assumption is violated, e.g. by the use of
2090 -- unchecked conversion, then it may be necessary to
2091 -- suppress this assumption using this keyword (which
2092 -- may be specified only in conjunction with any
2093 -- keyword above, other than NONE).
2097 -- NODOC (see /OPTIMIZE)
2101 -- /OUTPUT_FILE=fname
2102 --
2103 -- This has the same effect as /LIST except that the output is written
2104 -- to a file instead of to standard output. If the given fname
2105 -- does not start with a period, then it is the full name of the file
2106 -- to be written. If fname starts with a period, the name of the file
2107 -- is the concatenation of to the name of the file being compiled with
2108 -- fname where the period is replace by an underline. For example, if
2109 -- file xyz.adb is compiled with -gnatl=.lst, then the output is written
2110 -- to file xyz.adb_lst.
2114 -- /OVERFLOW_CHECKS=nn
2115 --
2116 -- Set default overflow cheecking mode. If nn is a single digit, in the
2117 -- range 0-3, it sets the overflow checking mode for all expressions,

2119 --
2120 -- 0 suppress overflow checks (SUPPRESSED)
2121 -- 1 all intermediate overflows checked (CHECKED)
2122 -- 2 minimize intermediate overflows (MINIMIZED)
2123 -- 3 eliminate intermediate overflows (ELIMINATED)
2124 --
2125 -- Otherwise nn can be two digits, both 0-3, and in this case the first
2126 -- digit sets the mode (using the above code) for expressions outside an
2127 -- assertion, and the second digit sets the mode for expressions within
2128 -- an assertion.
2139 -- /POINTER_SIZE=64 (D)
2140 -- /POINTER_SIZE[=(keyword[,...])]
2141 --
2142 -- Change how pointers and descriptors are allocated. The following

2149 -- subprograms and accept both 64bit and 32bit
2150 -- descriptors for calls to exported subprograms.
2151 --
2152 -- LONG Equivalent to option 64.
2153 --
2154 -- 32 Allocate all heap pointers in 32bit space and
2155 -- generate 32bit descriptors for Descriptor

2166 -- Reference Manual for full details.
2170 -- /PROJECT_FILE=filename
2171 --
2172 -- Specifies the main project file to be used. The project files rooted
2173 -- at the main project file will be parsed before the invocation of the

2226 -- is for the case of references to undefined variables.
2227 -- If a given variable is referenced several times, the
2228 -- normal format of messages produces one error. With

2230 -- error message.
2231 --
2232 -- IMMEDIATE Normally, the compiler saves up error messages and

2234 -- sequence. This keyword causes error messages to be
2235 -- generated as soon as they are detected. The use of
2236 -- IMMEDIATE usually causes error messages to be
2237 -- generated out of sequence. Use it when the compiler
2238 -- blows up due to an internal error. In this case, the
2239 -- error messages may be lost. Sometimes blowups are
2240 -- the result of mishandled error messages, so you may

2460 -- /STYLE_CHECKS[=(keyword,[...])]
2461 --
2462 -- Normally, GNAT permits any code layout consistent with the reference

2468 -- HTABS, IF_THEN, KEYWORD, LAYOUT, LINE_LENGTH,
2469 -- PRAGMA, REFERENCES, SPECS, TOKEN.
2470 --
2471 -- 1 .. 9 Specify indentation level from 1 to 9.
2472 -- The general style of required indentation is as
2473 -- specified by the examples in the Ada Reference
2474 -- Manual. Full line comments must be aligned with
2475 -- the -- starting on a column that is a multiple
2476 -- of the alignment level.
2477 --
2478 -- ATTRIBUTE Check attribute casing.
2479 -- Attribute names, including the case of keywords
2480 -- such as digits used as attributes names,
2481 -- must be written in mixed case, that is,
2482 -- the initial letter and any letter following an
2483 -- underscore must be uppercase.
2484 -- All other letters must be lowercase.
2485 --
2486 -- ARRAY_INDEXES Check indexes of array attributes.
2487 -- For array attributes First, Last, Range,
2488 -- or Length, the index number must be omitted
2489 -- for one-dimensional arrays and is required
2490 -- for multi-dimensional arrays.
2491 --
2492 -- BLANKS Blanks not allowed at statement end.
2493 -- Trailing blanks are not allowed at the end of
2494 -- statements. The purpose of this rule, together

2496 -- enforce a canonical format for the use of
2497 -- blanks to separate source tokens.
2498 --
2499 -- COMMENTS2 Check comments.
2500 -- COMMENTS Comments must meet the following set of rules:
2501 --
2502 -- * The "--" that starts the column must either
2503 -- start in column one, or else at least one
2504 -- blank must precede this sequence.
2505 --
2506 -- * Comments that follow other tokens on a line
2507 -- must have at least one blank following the
2508 -- "--" at the start of the comment.
2509 --
2510 -- * Full line comments must have two blanks
2511 -- following the "--" that starts the comment,
2512 -- with the following exceptions.
2513 --
2514 -- * A line consisting only of the "--"
2515 -- characters, possibly preceded by blanks is
2516 -- permitted.
2517 --
2518 -- * A comment starting with "--x" where x is
2519 -- a special character is permitted. This
2520 -- allows proper processing of the output
2521 -- generated by specialized tools including
2522 -- gnatprep (where --! is used) and the SPARK
2523 -- annotation language (where --# is used).
2524 -- For the purposes of this rule, a special
2525 -- character is defined as being in one of the
2526 -- ASCII ranges 16#21#..16#2F# or
2527 -- 16#3A#..16#3F#.
2528 --
2529 -- * A line consisting entirely of minus signs,
2530 -- possibly preceded by blanks, is permitted.
2531 -- This allows the construction of box
2532 -- comments where lines of minus signs are
2533 -- used to form the top and bottom of the box.
2534 --
2535 -- * If a comment starts and ends with "--" is
2536 -- permitted as long as at least one blank
2537 -- follows the initial "--". Together with
2538 -- the preceding rule, this allows the
2539 -- construction of box comments, as shown in
2540 -- the following example:
2541 --
2542 -- ---------------------------
2543 -- -- This is a box comment --
2544 -- ---------------------------
2545 --
2546 -- COMMENTS1 Check comments (single space).
2547 -- Like COMMENTS2, but the -- of a comment only
2548 -- requires one or more spaces following, instead
2549 -- of two or more spaces.
2550 --
2551 -- DOS_LINE_ENDINGS Check that no DOS line terminators are present
2552 -- All lines must be terminated by a single
2553 -- ASCII.LF character. In particular the DOS line
2554 -- terminator sequence CR / LF is not allowed).
2555 --
2556 -- END Check end/exit labels.
2557 -- Optional labels on end statements ending
2558 -- subprograms and on exit statements exiting
2559 -- named loops, are required to be present.
2560 --
2561 -- GNAT Enforces a set of style conventions that
2562 -- match the style used in the GNAT source code.
2563 -- This maybe useful when developing code that
2564 -- is eventually intended to be incorporated into
2565 -- GNAT. For further details, see GNAT sources.
2566 --
2567 -- HTABS No horizontal tabs.
2568 -- Horizontal tab characters are not permitted in
2569 -- the source text. Together with the BLANKS
2570 -- (no blanks at end of line) option, this
2571 -- enforces a canonical form for the use of blanks
2572 -- to separate source tokens.
2573 --
2574 -- IF_THEN Check if-then layout.
2575 -- The keyword then must appear either on the
2576 -- same line as the corresponding if, or on a line
2577 -- on its own, lined up under the if with at least
2578 -- one non-blank line in between containing all or
2579 -- part of the condition to be tested.
2580 --
2581 -- KEYWORD Check keyword casing.
2582 -- All keywords must be in lower case (with the
2583 -- exception of keywords such as digits used as
2584 -- attribute names to which this check does not
2585 -- apply).
2586 --
2587 -- LAYOUT Check layout.
2588 -- Layout of statement and declaration constructs
2589 -- must follow the recommendations in the Ada
2590 -- Reference Manual, as indicated by the form of
2591 -- the syntax rules. For example an else keyword
2592 -- must be lined up with the corresponding if
2593 -- keyword.
2594 --
2595 -- There are two respects in which the style rule
2596 -- enforced by this check option are more liberal
2597 -- than those in the Ada Reference Manual.
2598 -- First in the case of record declarations,
2599 -- it is permissible to put the record keyword on
2600 -- the same line as the type keyword, and then
2601 -- the end in end record must line up under type.
2602 -- For example, either of the following two
2603 -- layouts is acceptable:
2604 --
2605 -- type q is record
2606 -- a : integer;
2607 -- b : integer;
2608 -- end record;
2609 --
2610 -- type q is
2611 -- record
2612 -- a : integer;
2613 -- b : integer;
2614 -- end record;
2615 --
2616 -- Second, in the case of a block statement,
2617 -- a permitted alternative is to put the block
2618 -- label on the same line as the declare or begin
2619 -- keyword, and then line the end keyword up under
2620 -- the block label. For example both the following
2621 -- are permitted:
2622 --
2623 --
2624 --
2625 -- Block : declare
2626 -- A : Integer := 3;
2627 -- begin
2628 -- Proc (A, A);
2629 -- end Block;
2630 --
2631 -- Block :
2632 -- declare
2633 -- A : Integer := 3;
2634 -- begin
2635 -- Proc (A, A);
2636 -- end Block;
2637 --
2638 -- The same alternative format is allowed for
2639 -- loops. For example, both of the following are
2640 -- permitted:
2641 --
2642 --
2643 --
2644 -- Clear : while J < 10 loop
2645 -- A (J) := 0;
2646 -- end loop Clear;
2647 --
2648 -- Clear :
2649 -- while J < 10 loop
2650 -- A (J) := 0;
2651 -- end loop Clear;
2652 --
2653 --
2654 --
2655 -- LINE_LENGTH Check maximum line length.
2656 -- The length of source lines must not exceed 79
2657 -- characters, including any trailing blanks
2658 -- The value of 79 allows convenient display on
2659 -- an 80 character wide device or window, allowing
2660 -- for possible special treatment of 80 character
2661 -- lines.
2662 --
2663 -- NONE Clear any previously set style checks.
2664 --
2665 -- ORDERED_SUBPROGRAMS Check order of subprogram bodies.
2666 -- All subprogram bodies in a given scope (e.g.
2667 -- a package body) must be in alphabetical order.
2668 -- The ordering rule uses normal Ada rules for
2669 -- comparing strings, ignoring casing of letters,
2670 -- except that if there is a trailing numeric
2671 -- suffix, then the value of this suffix is used
2672 -- in the ordering (e.g. Junk2 comes before
2673 -- Junk10).
2674 --
2675 -- OVERRIDING_INDICATORS Check that overriding subprograms are
2676 -- explicitly marked as such. The declaration of
2677 -- a primitive operation of a type extension that
2678 -- overrides an inherited operation must carry
2679 -- an overriding indicator.
2680 --
2681 -- PRAGMA Check pragma casing.
2682 -- Pragma names must be written in mixed case,
2683 -- that is, the initial letter and any letter
2684 -- following an underscore must be uppercase.
2685 -- All other letters must be lowercase.
2686 --
2687 -- REFERENCES Check references.
2688 -- All identifier references must be cased in the
2689 -- same way as the corresponding declaration.
2690 -- No specific casing style is imposed on
2691 -- identifiers. The only requirement is for
2692 -- consistency of references with declarations.
2693 --
2694 -- SPECS Check separate specs.
2695 -- Separate declarations ("specs") are required
2696 -- for subprograms (a body is not allowed to serve
2697 -- as its own declaration). The only exception is
2698 -- that parameterless library level procedures are
2699 -- not required to have a separate declaration.
2700 -- This exception covers the most frequent form of
2701 -- main program procedures.
2702 --
2703 -- STANDARD_CASING Check casing of entities in Standard.
2704 -- Any identifier from Standard must be cased to
2705 -- match the presentation in the Ada Reference
2706 -- Manual (for example, Integer and ASCII.NUL).
2707 --
2708 -- TOKEN Check token spacing.
2709 -- The following token spacing rules are enforced:
2710 --
2711 -- * The keywords abs and not must be followed
2712 -- by a space.
2713 --
2714 -- * The token => must be surrounded by spaces.
2715 --
2716 -- * The token <> must be preceded by a space or
2717 -- a left parenthesis.
2718 --
2719 -- * Binary operators other than ** must be
2720 -- surrounded by spaces. There is no
2721 -- restriction on the layout of the ** binary
2722 -- operator.
2723 --
2724 -- * Colon must be surrounded by spaces.
2725 --
2726 -- * Colon-equal (assignment) must be surrounded
2727 -- by spaces.
2728 --
2729 -- * Comma must be the first non-blank character
2730 -- on the line, or be immediately preceded by
2731 -- a non-blank character, and must be followed
2732 -- by a space.
2733 --
2734 -- * If the token preceding a left paren ends
2735 -- with a letter or digit, then a space must
2736 -- separate the two tokens.
2737 --
2738 -- * A right parenthesis must either be the
2739 -- first non-blank character on a line, or it
2740 -- must be preceded by a non-blank character.
2741 --
2742 -- * A semicolon must not be preceded by
2743 -- a space, and must not be followed by
2744 -- a non-blank character.
2745 --
2746 -- * A unary plus or minus may not be followed
2747 -- by a space.
2748 --
2749 -- * A vertical bar must be surrounded by
2750 -- spaces.
2751 --
2752 -- In the above rules, appearing in column one is
2753 -- always permitted, that is, counts as meeting
2754 -- either a requirement for a required preceding
2755 -- space, or as meeting a requirement for no
2756 -- preceding space.
2757 --
2758 -- Appearing at the end of a line is also always
2759 -- permitted, that is, counts as meeting either
2760 -- a requirement for a following space,
2761 -- or as meeting a requirement for no following
2762 -- space.
2763 --
2764 -- UNNECESSARY_BLANK_LINES
2765 -- Check for unnecessary blank lines.
2766 -- A blank line is considered unnecessary if it
2767 -- appears at the end of the file, or if more
2768 -- than one blank line occurs in sequence.
2769 --
2770 -- VTABS No form feeds or vertical tabs.
2771 -- Form feeds or vertical tab characters are not
2772 -- permitted in the source text.
2773 --
2774 -- XTRA_PARENS Check for the use of an unnecessary extra
2775 -- level of parentheses (C - style) around
2776 -- conditions in if statements, while statements
2777 -- and exit statements.

2789 -- does not exist, it is created automatically.
2793 -- /SYMBOL_PREPROCESSING="symbol=value"
2794 --
2795 -- Define or redefine a preprocessing symbol, associated with value.
2796 -- If "=value" is not specified, then the value of the symbol is True.
2797 -- A symbol is an identifier, following normal Ada (case-insensitive)
2798 -- rules for its syntax, and value is any sequence (including an empty
2799 -- sequence) of characters from the set (letters, digits, period,
2800 -- underline). Ada reserved words may be used as symbols, with the
2801 -- exceptions of "if", "else", "elsif", "end", "and", "or" and "then".
2802 --
2803 -- A symbol declared with this qualifier on the command line replaces
2804 -- a symbol with the same name either in a definition file or specified
2805 -- with a switch -D in the preprocessor data file.

2813 -- /SYNTAX_ONLY
2814 --
2815 -- Run GNAT in syntax checking only mode. You can check a series of
2816 -- files in a single command, and can use wild cards to specify such a
2817 -- group of files.
2818 --
2819 -- You may use other qualifiers in conjunction with this qualifier. In
2820 -- particular, /LIST and /REPORT_ERRORS=VERBOSE are useful to control the
2821 -- format of any generated error messages.
2822 --
2823 -- The output is simply the error messages, if any. No object file or ALI
2824 -- file is generated by a syntax-only compilation. Also, no units other
2825 -- than the one specified are accessed. For example, if a unit "X" with's
2826 -- a unit "Y", compiling unit "X" in syntax check only mode does not
2827 -- access the source file containing unit "Y".
2828 --
2829 -- Normally, GNAT allows only a single unit in a source file. However,
2830 -- this restriction does not apply in syntax-check-only mode, and it is
2831 -- possible to check a file containing multiple compilation units
2832 -- concatenated together. This is primarily used by the GNAT CHOP
2833 -- command.

2854 --
2855 -- Cause GNAT to write the internal tree for a unit to a file (with the

2859 -- have to specify this switch in normal operation.
2863 -- /TRY_SEMANTICS
2864 -- /NOTRY_SEMANTICS
2865 --
2866 -- In normal operation mode the compiler first parses the program and
2867 -- determines if there are any syntax errors. If there are, appropriate
2868 -- error messages are generated and compilation is immediately
2869 -- terminated. This qualifier tells GNAT to continue with semantic
2870 -- analysis even if syntax errors have been found. This may enable the
2871 -- detection of more errors in a single run. On the other hand, the

3219 -- The use of a prefix of an access type in an
3220 -- indexed component, slice, or selected component
3221 -- without an explicit .all will generate
3222 -- a warning. With this warning enabled, access
3223 -- checks occur only at points where an explicit
3224 -- .all appears in the source code (assuming no
3225 -- warnings are generated as a result of this
3226 -- option). The default is that such warnings are
3227 -- not generated. Note that /WARNINGS=ALL does not
3228 -- affect the setting of this warning option.
3229 --
3230 -- NOIMPLICIT_DEREFERENCE Suppress warnings on implicit dereferencing.
3231 -- in indexed components, slices, and selected
3232 -- components.

3240 --
3241 -- ERRORS Warning messages are to be treated as errors.
3242 -- The warning string still appears, but the
3243 -- warning messages are counted as errors, and
3244 -- prevent the generation of an object file.
3245 --
3246 -- HIDING Activate warnings on hiding declarations.
3247 -- A declaration is considered hiding if it is
3248 -- for a non-overloadable entity, and it declares
3249 -- an entity with the same name as some other
3250 -- entity that is directly or use-visible. The
3251 -- default is that such warnings are not
3252 -- generated.
3253 --
3254 -- NOHIDING Suppress warnings on hiding declarations.
3255 --
3256 -- IMPLEMENTATION Activate warnings for a with of an internal

3258 -- from the Ada, Interfaces, GNAT, DEC or
3259 -- System hierarchies that is not documented in
3260 -- either the Ada Reference Manual or the GNAT
3261 -- Programmer's Reference Manual. Such units are
3262 -- intended only for internal implementation
3263 -- purposes and should not be with'ed by user
3264 -- programs. The default is that such warnings
3265 -- are generated.
3266 --
3267 -- NOIMPLEMENTATION Disables warnings for a with of an internal
3268 -- GNAT implementation unit.
3269 --
3270 -- INEFFECTIVE_INLINE Activate warnings on ineffective pragma Inlines
3271 -- Activates warnings for failure of front end
3272 -- inlining (activated by /INLINE=FULL) to inline
3273 -- a particular call. There are many reasons for
3274 -- not being able to inline a call, including most
3275 -- commonly that the call is too complex to
3276 -- inline. This warning can also be turned on
3277 -- using /INLINE=FULL.
3278 --
3279 -- NOINEFFECTIVE_INLINE Suppress warnings on ineffective pragma Inlines
3280 -- Suppresses warnings on ineffective pragma
3281 -- Inlines. If the inlining mechanism cannot
3282 -- inline a call, it will simply ignore the
3283 -- request silently.
3284 --
3285 -- MISSING_COMPONENT_CLAUSES
3286 -- Activate warnings for cases when there are

3291 -- Suppress warnings for cases when there are
3292 -- missing component clauses for a record type.
3293 --
3294 -- MISSING_PARENS
3295 -- Activate warnings for cases where parentheses
3296 -- are not used and the result is potential
3297 -- ambiguity from a reader's point of view.
3298 -- For example (not a > b) when a and b are
3299 -- modular means (not (a) > b) and very likely
3300 -- the programmer intended (not (a > b)).
3301 --
3302 -- NOMISSING_PARENS
3303 -- Suppress warnings for cases where parentheses
3304 -- are not used and the result is potential
3305 -- ambiguity from a reader's point of view.
3306 --
3307 -- MODIFIED_UNREF Activates warnings for variables that are
3308 -- assigned (using an initialization value or with
3309 -- one or more assignment statements) but whose
3310 -- value is never read. The warning is suppressed
3311 -- for volatile variables and also for variables
3312 -- that are renamings of other variables or for
3313 -- which an address clause is given. This warning
3314 -- can also be turned on using /WARNINGS/OPTIONAL.
3315 --
3316 -- NOMODIFIED_UNREF Disables warnings for variables that are
3317 -- assigned or initialized, but never read.
3318 --
3319 -- NORMAL Sets normal warning mode, in which enabled
3320 -- warnings are issued and treated as warnings
3321 -- rather than errors. This is the default mode.
3322 -- It can be used to cancel the effect of an
3323 -- explicit /WARNINGS=SUPPRESS or
3324 -- /WARNINGS=ERRORS. It also cancels the effect
3325 -- of the implicit /WARNINGS=ERRORS that is
3326 -- activated by the use of /STYLE=GNAT.
3327 --
3328 -- OBSOLESCENT Activates warnings for calls to subprograms
3329 -- marked with pragma Obsolescent and for use of
3330 -- features in Annex J of the Ada Reference
3331 -- Manual. In the case of Annex J, not all
3332 -- features are flagged. In particular use of the
3333 -- renamed packages (like Text_IO), use of package
3334 -- ASCII and use of the attribute 'Constrained are
3335 -- not flagged, since these are very common and
3336 -- would generate many annoying positive warnings.
3337 -- The default is that such warnings are not
3338 -- generated.
3339 --
3340 -- NOOBSOLESCENT Disables warnings on use of obsolescent
3341 -- features.
3342 --
3343 -- OBJECT_RENAME Activate warnings for non limited objects
3344 -- renaming parameterless functions.
3345 --
3346 -- NOOBJECT_RENAME Suppress warnings for non limited objects
3347 -- renaming parameterless functions.
3348 --
3349 -- OPTIONAL Equivalent to ALL.
3350 --
3351 -- NOOPTIONAL Equivalent to NOALL.
3352 --
3353 -- OVERLAYS Activate warnings for possibly unintended
3354 -- initialization effects of defining address
3355 -- clauses that cause one variable to overlap
3356 -- another. The default is that such warnings
3357 -- are generated.
3358 --
3359 -- NOOVERLAYS Suppress warnings on possibly unintended
3360 -- initialization effects of defining address
3361 -- clauses that cause one variable to overlap
3362 -- another.
3363 --
3364 -- REDUNDANT Activate warnings for redundant constructs.
3365 -- In particular assignments of a variable to
3366 -- itself, and a type conversion that converts
3367 -- an object to its own type. The default
3368 -- is that such warnings are not generated.
3369 --
3370 -- NOREDUNDANT Suppress warnings for redundant constructs.
3371 --
3372 -- SUPPRESS Completely suppress the output of all warning
3373 -- messages. Same as /NOWARNINGS.
3374 --
3375 -- UNCHECKED_CONVERSIONS Activates warnings on unchecked conversions.
3376 -- Causes warnings to be generated for
3377 -- unchecked conversions when the two types are
3378 -- known at compile time to have different sizes.
3379 -- The default is that such warnings are

3381 --
3382 -- NOUNCHECKED_CONVERSIONS Suppress warnings for unchecked conversions.
3383 --
3384 -- UNINITIALIZED Generate warnings for uninitialized variables.
3385 -- This is a GCC option, not an Ada option.
3386 -- You must also specify the /OPTIMIZE qualifier
3387 -- with a value other than NONE (in other words,
3388 -- this keyword works only if optimization is
3389 -- turned on).
3390 --
3391 -- UNREFERENCED_FORMALS Activate warnings on unreferenced formals.
3392 -- Causes a warning to be generated if a formal
3393 -- parameter is not referenced in the body of
3394 -- the subprogram. This warning can also be turned
3395 -- on using option ALL or UNUSED.
3396 --
3397 -- NOUNREFERENCED_FORMALS Suppress warnings on unreferenced formals.
3398 -- Suppresses warnings for unreferenced formal
3399 -- parameters. Note that the combination UNUSED
3400 -- followed by NOUNREFERENCED_FORMALS has the
3401 -- effect of warning on unreferenced entities
3402 -- other than subprogram formals.
3403 --
3404 -- UNUSED Activates warnings to be generated for entities
3405 -- that are defined but not referenced, and for
3406 -- units that are with'ed and not referenced. In
3407 -- the case of packages, a warning is also
3408 -- generated if no entities in the package are
3409 -- referenced. This means that if the package
3410 -- is referenced but the only references are in
3411 -- use clauses or renames declarations, a warning
3412 -- is still generated. A warning is also generated
3413 -- for a generic package that is with'ed but never
3414 -- instantiated. In the case where a package or
3415 -- subprogram body is compiled, and there is a
3416 -- with on the corresponding spec that is only
3417 -- referenced in the body, a warning is also
3418 -- generated, noting that the with can be moved
3419 -- to the body. The default is that such warnings
3420 -- are not generated.
3421 --
3422 -- NOUNUSED Suppress warnings for unused entities and
3423 -- packages.
3424 --
3425 -- VARIABLES_UNINITIALIZED Activates warnings on unassigned variables.
3426 -- Causes warnings to be generated when a variable

3428 -- uninitialized.
3429 -- The default is that such warnings are
3430 -- generated.
3431 --
3432 -- NOVARIABLES_UNINITIALIZED Suppress warnings for uninitialized
3433 -- variables.
3437 -- NODOC (see /WARNINGS)
3441 -- /NO_BACK_END_WARNINGS
3442 --
3443 -- Inhibit all warning messages of the GCC back-end.
3458 -- /NOWIDE_CHARACTER_ENCODING (D)
3459 -- /WIDE_CHARACTER_ENCODING[=encode-type]
3460 --
3461 -- Specifies the mechanism used to encode wide characters. 'encode-type'
3462 -- is one of the following:
3463 --
3464 -- BRACKETS (D) A wide character is encoded as ["xxxx"] where XXXX
3465 -- are four hexadecimal digits representing the coding
3466 -- ('Pos value) of the character in type
3467 -- Wide_Character. The hexadecimal digits may use upper
3468 -- or lower case letters.
3469 --
3470 -- This notation can also be used for upper half
3471 -- Character values using the format ["xx"] where XX is
3472 -- two hexadecimal digits representing the coding ('Pos
3473 -- value) of the character in type Character (or
3474 -- Wide_Character). The hexadecimal digits may use upper
3475 -- of lower case.
3476 --
3477 -- NONE No wide characters are allowed. Same
3478 -- as /NOWIDE_CHARACTER_ENCODING.
3479 --
3480 -- HEX In this encoding, a wide character is represented by
3481 -- the following five character sequence: ESC a b c d
3482 -- Where 'a', 'b', 'c', and 'd' are the four hexadecimal
3483 -- characters (using uppercase letters) of the wide
3484 -- character code. For example, ESC A345 is used to
3485 -- represent the wide character with code 16#A345#. This
3486 -- scheme is compatible with use of the full
3487 -- Wide_Character set.
3488 --
3489 -- UPPER The wide character with encoding 16#abcd# where the
3490 -- upper bit is on (in other words, "a" is in the range
3491 -- 8-F) is represented as two bytes, 16#ab# and 16#cd#.
3492 -- The second byte may never be a format control
3493 -- character, but is not required to be in the upper
3494 -- half. This method can be also used for shift-JIS or
3495 -- EUC, where the internal coding matches the external
3496 -- coding.
3497 --
3498 -- SHIFT_JIS A wide character is represented by a two-character
3499 -- sequence, 16#ab# and 16#cd#, with the restrictions
3500 -- described for upper-half encoding as described above.
3501 -- The internal character code is the corresponding JIS
3502 -- character according to the standard algorithm for
3503 -- Shift-JIS conversion. Only characters defined in the
3504 -- JIS code set table can be used with this encoding
3505 -- method.
3506 --
3507 -- UTF8 A wide character is represented using
3508 -- UCS Transformation Format 8 (UTF-8) as defined in Annex
3509 -- R of ISO 10646-1/Am.2. Depending on the character
3510 -- value, the representation is a one, two, or three byte
3511 -- sequence:
3512 --
3513 -- 16#0000#-16#007f#: 2#0xxxxxxx#
3514 -- 16#0080#-16#07ff#: 2#110xxxxx# 2#10xxxxxx#
3515 -- 16#0800#-16#ffff#: 2#1110xxxx# 2#10xxxxxx# 2#10xxxxxx#
3516 --
3517 -- where the xxx bits correspond to the left-padded bits
3518 -- of the 16-bit character value. Note that all lower
3519 -- half ASCII characters are represented as ASCII bytes
3520 -- and all upper half characters and other wide characters
3521 -- are represented as sequences of upper-half (The full
3522 -- UTF-8 scheme allows for encoding 31-bit characters as
3523 -- 6-byte sequences, but in this implementation, all UTF-8
3524 -- sequences of four or more bytes length will be treated
3525 -- as illegal).
3526 --
3527 -- EUC A wide character is represented by a two-character
3528 -- sequence 16#ab# and 16#cd#, with both characters being
3529 -- in the upper half. The internal character code is the
3530 -- corresponding JIS character according to the EUC
3531 -- encoding algorithm. Only characters defined in the JIS
3532 -- code set table can be used with this encoding method.
3536 -- NODOC (see /WIDE_CHARACTER_ENCODING)
3540 -- /NOXDEBUG (D)
3541 -- /XDEBUG
3542 --
3543 -- Output expanded source files for source level debugging.
3544 -- The expanded source (see /EXPAND_SOURCE) is written to files
3545 -- with names formed by appending "_DG" to the input file name,
3546 -- The debugging information generated by the /DEBUG qualifier will then
3547 -- refer to the generated file. This allows source level debugging using
3548 -- the generated code which is sometimes useful for complex code, for
3549 -- example to find out exactly which part of a complex construction
3550 -- raised an exception. The maximum line length for the output is 72.

3555 --
3556 -- Output expanded source files for source level debugging.
3557 -- The expanded source (see /EXPAND_SOURCE) is written to files
3558 -- with names formed by appending "_DG" to the input file name,

3563 -- raised an exception. The parameter is the maximum line length for
3564 -- the output.
3571 -- /XREF[=keyword]
3572 --
3573 -- Normally the compiler generates full cross-referencing information in

4606 -- installation problem, it will be caught when GNAT MAKE binds your
4607 -- program). You may have to specify this qualifier if you are working on
4608 -- GNAT itself. The vast majority of GNAT MAKE users never need to
4609 -- specify this switch. All GNAT internal files with will be compiled
4610 -- with /STYLE_CHECK=GNAT.
4614 -- /NOALL_PROJECTS (D)
4615 -- /ALL_PROJECTS
4616 --
4617 -- Implies /Unique.
4618 -- When used without project files, it is equivalent to /UNIQUE.
4619 -- When used with a project file with no main (neither on the command
4620 -- line nor in the attribute Main) check every source of every project,
4621 -- recompile all sources that are not up to date and rebuild libraries
4622 -- if necessary.
4626 -- /BINDER_QUALIFIERS
4627 --
4628 -- Any qualifiers specified after this qualifier other than
4629 -- /COMPILER_QUALIFIERS, /LINKER_QUALIFIERS and /MAKE_QUALIFIERS will be
4630 -- passed to any GNAT BIND commands generated by GNAT MAKE.
4634 -- /BND_LNK_FULL_PROJECT
4635 --
4636 -- Bind and link all sources of a project, without any consideration
4637 -- to attribute Main, if there is one. This qualifier need to be
4638 -- used in conjunction with the /PROJECT_FILE= qualifier and cannot
4639 -- be used with a main subprogram on the command line or for
4640 -- a library project file. As the binder is invoked with the option
4641 -- meaning "No Ada main subprogram", the user must ensure that the
4642 -- proper options are specified to the linker. This qualifier is
4643 -- normally used when the main subprogram is in a foreign language
4644 -- such as C.
4648 -- /COMPILER_QUALIFIERS
4649 --
4650 -- Any qualifiers specified after this qualifier other than
4651 -- /BINDER_QUALIFIERS, /LINKER_QUALIFIERS and /MAKE_QUALIFIERS will be
4652 -- passed to any GNAT COMPILE commands generated by GNAT MAKE.
4656 -- /CONDITIONAL_SOURCE_SEARCH=dir
4657 --
4658 -- Equivalent to "/SOURCE_SEARCH=dir /SKIP_MISSING=dir".
4662 -- /NOCONTINUE_ON_ERROR (D)
4663 -- /CONTINUE_ON_ERROR
4664 --
4665 -- Keep going. Continue as much as possible after a compilation error.
4666 -- To ease the programmer's task in case of compilation errors, the list
4667 -- of sources for which the compile fails is given when GNAT MAKE
4668 -- terminates.
4672 -- /CURRENT_DIRECTORY (D)
4673 -- /NOCURRENT_DIRECTORY
4674 --
4675 -- Look for source, library or object files in the default directory.
4679 -- /NODEPENDENCIES_LIST (D)
4680 -- /DEPENDENCIES_LIST
4681 --
4682 -- Check if all objects are up to date. If they are, output the object
4683 -- dependences to SYS$OUTPUT in a form that can be directly exploited in
4684 -- a Unix-style Makefile. By default, each source file is prefixed with
4685 -- its (relative or absolute) directory name. This name is whatever you
4686 -- specified in the various /SOURCE_SEARCH and /SEARCH qualifiers. If
4687 -- you also specify the /QUIET qualifier, only the source file names,
4688 -- without relative paths, are output. If you just specify the
4689 -- /DEPENDENCY_LIST qualifier, dependencies of the GNAT internal system
4690 -- files are omitted. This is typically what you want. If you also
4691 -- specify the /ALL_FILES qualifier, dependencies of the GNAT internal
4692 -- files are also listed. Note that dependencies of the objects in
4693 -- external Ada libraries (see the /SKIP_MISSING qualifier) are never
4694 -- reported.
4698 -- /DIRECTORY_OBJECTS=<file>
4699 --
4700 -- Put all object files and .ALI files in <file>.
4701 -- This qualifier is not compatible with /PROJECT_FILE.
4705 -- /NOPLAY_PROGRESS (D)
4706 -- /DISPLAY_PROGRESS
4707 --
4708 -- Display progress for each source, up to date or not, as a single line
4709 -- completed x out of y (zz%)
4710 -- If the file needs to be compiled this is displayed after the
4711 -- invocation of the compiler. These lines are displayed even in quiet
4712 -- output mode (/QUIET).
4716 -- /NODO_OBJECT_CHECK (D)
4717 -- /DO_OBJECT_CHECK
4718 --
4719 -- Don't compile, bind, or link. Output a single command that will
4720 -- recompile an out of date unit, if any. Repeated use of this option,
4721 -- followed by carrying out the indicated compilation, will eventually
4722 -- result in recompiling all required units.
4723 --
4724 -- If any ALI is missing during the process, GNAT MAKE halts and
4725 -- displays an error message.
4729 -- /EXECUTABLE=exec-name
4730 --
4731 -- The name of the final executable program will be 'exec_name'. If this
4732 -- qualifier is omitted the default name for the executable will be the
4733 -- name of the input file with an EXE filetype. You may prefix
4734 -- 'exec_name' with a relative or absolute directory path.
4738 -- /EXTERNAL_REFERENCE="name=val"
4739 --
4740 -- Specifies an external reference to the project manager. Useful only if
4741 -- /PROJECT_FILE is used.
4742 --
4743 -- Example:
4744 -- /EXTERNAL_REFERENCE="DEBUG=TRUE"
4748 -- /NOFOLLOW_LINKS_FOR_FILES (D)
4749 -- /FOLLOW_LINKS_FOR_FILES
4750 --
4751 -- Follow links when parsing project files
4755 -- /NOFORCE_COMPILE (D)
4756 -- /FORCE_COMPILE
4757 --
4758 -- Force recompilations. Recompile all sources, even though some object
4759 -- files may be up to date, but don't recompile predefined or GNAT
4760 -- internal files unless the /ALL_FILES qualifier is also specified.
4764 -- /NOFULL_PATH_IN_BRIEF_MESSAGES (D)
4765 -- /FULL_PATH_IN_BRIEF_MESSAGES
4766 --
4767 -- When using project files, if some errors or warnings are detected
4768 -- during parsing and verbose mode is not in effect (no use of qualifier
4769 -- /VERBOSE), then error lines start with the full path name of the
4770 -- project file, rather than its simple file name.
4774 -- /NOHIGH_VERBOSITY (D)
4775 -- /HIGH_VERBOSITY
4776 --
4777 -- Displays the reason for all recompilations GNAT MAKE decides are
4778 -- necessary, in high verbosity. Equivalent to /VERBOSE.
4782 -- /NOIN_PLACE (D)
4783 -- /IN_PLACE
4784 --
4785 -- In normal mode, GNAT MAKE compiles all object files and ALI files
4786 -- into the current directory. If the /IN_PLACE switch is used,
4787 -- then instead object files and ALI files that already exist are over-
4788 -- written in place. This means that once a large project is organized
4789 -- into separate directories in the desired manner, then GNAT MAKE will
4790 -- automatically maintain and update this organization. If no ALI files
4791 -- are found on the Ada object path, the new object and ALI files are
4792 -- created in the directory containing the source being compiled.
4796 -- /SOURCE_INDEX=nnn
4797 --
4798 -- Specifies the index of the units in the source file
4799 -- By default, source files are mono-unit and there is no index
4800 -- When /SOURCE_INDEX=nnn is specified, only one main may be specified
4801 -- on the command line.
4805 -- /LIBRARY_SEARCH=(directory[,...])
4806 --
4807 -- Add the specified directories to the list of directories in which the
4808 -- linker will search for libraries.
4812 -- /LINKER_QUALIFIERS
4813 --
4814 -- Any qualifiers specified after this qualifier other than
4815 -- /COMPILER_QUALIFIERS, /BINDER_QUALIFIERS and /MAKE_QUALIFIERS will be
4816 -- passed to any GNAT LINK commands generated by GNAT LINK.
4820 -- /NOLOW_VERBOSITY (D)
4821 -- /LOW_VERBOSITY
4822 --
4823 -- Displays the reason for all recompilations GNAT MAKE decides are
4824 -- necessary, in low verbosity, that is with less output than
4825 -- /MEDIUM_VERBOSITY, /HIGH_VERBOSITY or /VERBOSE.
4829 -- /MAKE_QUALIFIERS
4830 --
4831 -- Any qualifiers specified after this qualifier other than
4832 -- /COMPILER_QUALIFIERS, /BINDER_QUALIFIERS and /LINKER_QUALIFIERS
4833 -- are for the benefit of GNAT MAKE itself.
4837 -- /NOMAPPING (D)
4838 -- /MAPPING
4839 --
4840 -- Use a mapping file. A mapping file is a way to communicate to the
4841 -- compiler two mappings: from unit names to file names (without any
4842 -- directory information) and from file names to path names (with full
4843 -- directory information). These mappings are used by the compiler to
4844 -- short-circuit the path search. When GNAT MAKE is invoked with this
4845 -- qualifier, it will create a mapping file, initially populated by the
4846 -- project manager, if /PROJECT_File= is used, otherwise initially empty.
4847 -- Each invocation of the compiler will add the newly accessed sources to
4848 -- the mapping file. This will improve the source search during the next
4849 -- invocations of the compiler
4853 -- /NOMEDIUM_VERBOSITY (D)
4854 -- /MEDIUM_VERBOSITY
4855 --
4856 -- Displays the reason for all recompilations GNAT MAKE decides are
4857 -- necessary, in medium verbosity, that is with potentially less output
4858 -- than /HIGH_VERBOSITY or /VERBOSE.
4867 -- /MESSAGES_PROJECT_FILE[=messages-option]
4868 --
4869 -- Specifies the "verbosity" of the parsing of project files.
4870 -- messages-option may be one of the following:
4871 --
4872 -- DEFAULT (D) No messages are output if there is no error or warning.
4873 --
4874 -- MEDIUM A small number of messages are output.
4875 --
4876 -- HIGH A great number of messages are output, most of them not
4877 -- being useful for the user.
4881 -- /NOMINIMAL_RECOMPILATION (D)
4882 -- /MINIMAL_RECOMPILATION
4883 --
4884 -- Specifies that the minimum necessary amount of recompilation
4885 -- be performed. In this mode GNAT MAKE ignores time stamp differences
4886 -- when the only modifications to a source file consist in
4887 -- adding/removing comments, empty lines, spaces or tabs.
4891 -- /NOCREATE_MISSING_DIRS (D)
4892 -- /CREATE_MISSING_DIRS
4893 --
4894 -- When an object directory, a library directory or an exec directory
4895 -- in missing, attempt to create the directory.
4899 -- /NOLINK
4900 --
4901 -- Compile only. Do not perform binding and linking. If the root unit is
4902 -- not a main unit, this is the default. Otherwise GNAT MAKE will
4903 -- attempt binding and linking unless all objects are up to date and the
4904 -- executable is more recent than the objects.
4905 -- This is equivalent to /ACTIONS=COMPILE
4909 -- /NOMAIN
4910 --
4911 -- No main subprogram. Bind and link the program even if the unit name
4912 -- given on the command line is a package name. The resulting executable
4913 -- will execute the elaboration routines of the package and its closure,
4914 -- then the finalization routines.
4918 -- /NON_PROJECT_UNIT_COMPILATION
4919 --
4920 -- Normally, when using project files, a unit that is not part of any
4921 -- project file, cannot be compile. These units may be compile, when
4922 -- needed, if this qualifier is specified.
4926 -- /NOSTD_INCLUDES
4927 --
4928 -- Do not look for sources the in the system default directory.
4932 -- /NOSTD_LIBRARIES
4933 --
4934 -- Do not look for library files in the system default directory.
4938 -- /OBJECT_SEARCH=(directory[,...])
4939 --
4940 -- When looking for library and object files look also in the specified
4941 -- directories.
4945 -- /NOPROCESSES (D)
4946 -- /PROCESSES=NNN
4947 --
4948 -- Use NNN processes to carry out the (re)compilations. If you have a
4949 -- multiprocessor machine, compilations will occur in parallel. In the
4950 -- event of compilation errors, messages from various compilations might
4951 -- get interspersed (but GNAT MAKE will give you the full ordered list of
4952 -- failing compiles at the end). This can at times be annoying. To get a
4953 -- clean list of error messages don't use this qualifier.
4957 -- NODOC (see /PROCESS)
4961 -- /PROJECT_FILE=filename
4962 --
4963 -- Specifies the main project file to be used. The project files rooted
4964 -- at the main project file will be parsed before any other processing to
4965 -- set the building environment.
4969 -- /NOQUIET (D)
4970 -- /QUIET
4971 --
4972 -- When this qualifiers is specified, the commands carried out by GNAT
4973 -- MAKE are not displayed.
4977 -- /NOREASONS (D)
4978 -- /REASONS
4979 --
4980 -- Displays the reason for all recompilations GNAT MAKE decides are
4981 -- necessary.
4985 -- /RUNTIME_SYSTEM=xxx
4986 --
4987 -- Build against an alternate runtime system named xxx or RTS-xxx.
4991 -- /SEARCH=(directory[,...])

4999 --
5000 -- When project files are used, do not allow simultaneous compilations
5001 -- for the same object directory.

5013 -- When looking for source files also look in the specified directories.
5017 -- /SRC_INFO=source-info-file
5018 --
5019 -- Specify a source info file to be read or written by the Project
5020 -- Manager when project files are used.
5024 -- /NOSTANDARD_OUTPUT_FOR_COMMANDS (D)
5025 -- /STANDARD_OUTPUT_FOR_COMMANDS
5026 --
5027 -- Output the commands for the compiler, the binder and the linker
5028 -- on SYS$OUTPUT, instead of SYS$ERROR.
5032 -- /SUBDIRS=dir
5033 --
5034 -- The actual directories (object, exec, library, ...) are subdirectories
5035 -- of the directory specified in the project file. If the subdirectory
5036 -- does not exist, it is created automatically.
5040 -- /NOSWITCH_CHECK (D)
5041 -- /SWITCH_CHECK
5042 --
5043 -- Recompile if compiler switches have changed since last compilation.
5044 -- All compiler switches but -I and -o are taken into account in the
5045 -- following way: orders between different "first letter" switches are
5046 -- ignored, but orders between same switches are taken into account.
5047 -- For example, -O -O2 is different than -O2 -O, but -g -O is equivalent
5048 -- to -O -g.
5052 -- /NOUNCHECKED_SHARED_LIB_IMPORTS (D)
5053 -- /UNCHECKED_SHARED_LIB_IMPORTS
5054 --
5055 -- Allow shared library projects to import static library projects
5059 -- /NOUNIQUE (D)
5060 -- /UNIQUE
5061 --
5062 -- Recompile at most the main file. It implies /ACTIONS=COMPILE.
5063 -- Combined with /FORCE_COMPILE, it is equivalent to calling the compiler
5064 -- directly.
5068 -- /USE_MAPPING_FILE=file_name
5069 --
5070 -- Use a specific mapping file. The file 'file_name', specified as a path
5071 -- name (absolute or relative) by this qualifier, should already exist,
5072 -- otherwise the qualifier is ineffective. The specified mapping file
5073 -- will be communicated to the compiler. This switch is not compatible
