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)

1253 -- 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 for integer operations and
1351 -- checks for access before elaboration on subprogram
1352 -- calls. This causes GNAT to generate slower and larger
1353 -- executable programs by adding code to check for both
1354 -- overflow and division by zero (resulting in raising
1355 -- "Constraint_Error" as required by Ada semantics).
1356 -- Similarly, GNAT does not generate elaboration check
1357 -- by default, and you must specify this keyword to
1358 -- enable them.
1359 --
1360 -- Note that this keyword does not affect the code
1361 -- generated for any floating-point operations; it
1362 -- applies only to integer operations. For the case of
1363 -- floating-point, GNAT has the "Machine_Overflows"
1364 -- attribute set to "False" and the normal mode of
1365 -- operation is to generate IEEE NaN and infinite values
1366 -- on overflow or invalid operations (such as dividing
1367 -- 0.0 by 0.0).
1368 --
1369 -- ELABORATION Enables dynamic checks for access-before-elaboration
1370 -- on subprogram calls and generic instantiations.
1371 --
1372 -- ASSERTIONS The pragmas "Assert" and "Debug" normally have no
1373 -- effect and are ignored. This keyword causes "Assert"
1374 -- and "Debug" pragmas to be activated, as well as
1375 -- "Check", "Precondition" and "Postcondition" pragmas.
1376 --
1377 -- SUPPRESS_ALL Suppress all runtime checks as though you have
1378 -- "pragma Suppress (all_checks)" in your source. Use
1379 -- this switch to improve the performance of the code at
1380 -- the expense of safety in the presence of invalid data
1381 -- or program bugs.
1382 --
1383 -- UNSUPPRESS_ALL Cancels effect of previous SUPPRESS_ALL.
1384 --
1385 -- DEFAULT Suppress the effect of any option OVERFLOW or
1386 -- ASSERTIONS.
1387 --
1388 -- FULL (D) Similar to OVERFLOW, but suppress the effect of any
1389 -- option ELABORATION or SUPPRESS_ALL.
1390 --
1391 -- These keywords only control the default setting of the checks. You
1392 -- may modify them using either "Suppress" (to remove checks) or
1393 -- "Unsuppress" (to add back suppressed checks) pragmas in your program
1394 -- source.
1398 -- NODOC (see /CHECKS)
1402 -- /NOCOMPRESS_NAMES (D)
1403 -- /COMPRESS_NAMES
1404 --
1405 -- Compress debug information and external symbol name table entries.
1406 -- In the generated debugging information, and also in the case of long
1407 -- external names, the compiler uses a compression mechanism if the name
1408 -- is very long. This compression method uses a checksum, and avoids
1409 -- trouble on some operating systems which have difficulty with very long
1410 -- names.
1414 -- /CONFIGURATION_PRAGMAS_FILE=file

1423 -- Look for source files in the default directory.
1427 -- /DATA_PREPROCESSING=file_name
1428 --
1429 -- This qualifier indicates to the compiler the file name (without
1430 -- directory information) of the preprocessor data file to use.
1431 -- The preprocessor data file should be found in the source directories.
1432 --
1433 -- A preprocessing data file is a text file with significant lines
1434 -- indicating how should be preprocessed either a specific source or all
1435 -- sources not mentioned in other lines. A significant line is a non
1436 -- empty, non comment line. Comments are similar to Ada comments.
1437 --
1438 -- Each significant line starts with either a literal string or the
1439 -- character '*'. A literal string is the file name (without directory
1440 -- information) of the source to preprocess. A character '*' indicates the
1441 -- preprocessing for all the sources that are not specified explicitly on
1442 -- other lines. It is an error to have two lines with the same file name
1443 -- or two lines starting with the character '*'.
1444 --
1445 -- After the file name or the character '*', another optional literal
1446 -- string indicating the file name of the definition file to be used for
1447 -- preprocessing. (see 15.3 Form of Definitions File. The definition files
1448 -- are found by the compiler in one of the source directories. In some
1449 -- cases, when compiling a source in a directory other than the current
1450 -- directory, if the definition file is in the current directory, it may
1451 -- be necessary to add the current directory as a source directory through
1452 -- qualifier "/SEARCH=[]", otherwise the compiler would not find the
1453 -- definition file.
1454 --
1455 -- Then, optionally, switches similar to those of gnatprep may be found.
1456 -- Those switches are:
1457 --
1458 -- -b Causes both preprocessor lines and the lines deleted by
1459 -- preprocessing to be replaced by blank lines, preserving
1460 -- the line number. This switch is always implied;
1461 -- however, if specified after `-c' it cancels the effect
1462 -- of `-c'.
1463 --
1464 -- -c Causes both preprocessor lines and the lines deleted by
1465 -- preprocessing to be retained as comments marked with
1466 -- the special string "--! ".
1467 --
1468 -- -Dsymbol=value Define or redefine a symbol, associated with value.
1469 -- A symbol is an Ada identifier, or an Ada reserved word,
1470 -- with the exception of "if", "else", "elsif", "end",
1471 -- "and", "or" and "then". value is either a literal
1472 -- string, an Ada identifier or any Ada reserved word.
1473 -- A symbol declared with this switch replaces a symbol
1474 -- with the same name defined in a definition file.
1475 --
1476 -- -s Causes a sorted list of symbol names and values to be
1477 -- listed on the standard output file.

1479 -- -u Causes undefined symbols to be treated as having the
1480 -- value FALSE in the context of a preprocessor test.
1481 -- In the absence of this option, an undefined symbol

1718 -- the umlaut used in German.
1719 --
1720 -- You may use any of these extended characters freely

1800 -- /NOINLINE (D)
1801 -- /INLINE[=keyword]
1802 --
1803 -- Selects the level of inlining for your program. In the absence of this
1804 -- qualifier, GNAT does not attempt inlining across units and does not
1805 -- need to access the bodies of subprograms for which "pragma Inline" is

1807 --
1808 -- The supported keywords are as follows:
1809 --
1810 -- PRAGMA (D) Recognize and process "Inline" pragmas. However,
1811 -- for the inlining to actually occur, optimization
1812 -- must be enabled. This enables inlining across unit
1813 -- boundaries, that is, inlining a call in one unit of
1814 -- a subprogram declared in a with'ed unit. The compiler
1815 -- will access these bodies, creating an extra source
1816 -- dependency for the resulting object file, and where
1817 -- possible, the call will be inlined.
1818 --
1819 -- This qualifier also turns on full optimization and
1820 -- requests GNAT to try to attempt automatic inlining
1821 -- of small subprograms within a unit.
1822 --
1823 -- Specifying /OPTIMIZE=NONE will disable the main effect
1824 -- of this qualifier, but you may specify other
1825 -- optimization options, to get either lower
1826 -- (/OPTIMIZE=SOME) or higher (/OPTIMIZE=UNROLL_LOOPS)
1827 -- levels of optimization.
1828 --
1829 -- PRAGMA_LEVEL_1

1832 --
1833 -- PRAGMA_LEVEL_2
1834 -- Direct control of the level of "Inline" pragmas
1835 -- optimization with full inlining across modules.
1836 --
1837 -- FULL Front end inlining. The front end inlining activated
1838 -- by this switch is generally more extensive, and quite
1839 -- often more effective than the standard PRAGMA inlining
1840 -- mode. It will also generate additional dependencies.

1900 -- qualifier is also present.
1904 -- /MAPPING_FILE=file_name
1905 --
1906 -- Use mapping file file_name
1907 --
1908 -- A mapping file is a way to communicate to the compiler two mappings:
1909 -- from unit names to file names (without any directory information) and
1910 -- from file names to path names (with full directory information).
1911 -- These mappings are used by the compiler to short-circuit the path
1912 -- search.
1913 --
1914 -- The use of mapping files is not required for correct operation of the
1915 -- compiler, but mapping files can improve efficiency, particularly when
1916 -- sources are read over a slow network connection. In normal operation,
1917 -- you need not be concerned with the format or use of mapping files,
1918 -- and /MAPPING_FILE is not a qualifier that you would use explicitly.
1919 -- It is intended only for use by automatic tools such as GNAT MAKE
1920 -- running under the project file facility. The description here of the
1921 -- format of mapping files is provided for completeness and for possible
1922 -- use by other tools.
1923 --
1924 -- A mapping file is a sequence of sets of three lines. In each set, the
1925 -- first line is the unit name, in lower case, with "%s" appended for
1926 -- specifications and "%b" appended for bodies; the second line is the
1927 -- file name; and the third line is the path name.
1928 --
1929 -- Example:
1930 --
1931 -- main%b
1932 -- main.2_ada
1933 -- /gnat/project1/sources/main.2_ada
1934 --
1935 -- When qualifier ?MAPPING_FILE is specified, the compiler will create in
1936 -- memory the two mappings from the specified file. If there is any
1937 -- problem (non existent file, truncated file or duplicate entries),
1938 -- no mapping will be created.
1939 --
1940 -- Several /MAPPING_FILE qualifiers may be specified; however, only the
1941 -- last one on the command line will be taken into account.
1942 --
1943 -- When using a project file, GNAT MAKE creates a temporary mapping file
1944 -- and communicates it to the compiler using this switch.
1949 -- /MAX_INSTANTIATIONS=nnn
1950 --
1951 -- Specify the maximum number of instantiations permitted. The default
1952 -- value is 8000, which is probably enough for all programs except those
1953 -- containing some kind of runaway unintended instantiation loop.
1962 -- /MESSAGES_PROJECT_FILE[=messages-option]
1963 --
1964 -- Specifies the "verbosity" of the parsing of project files.
1965 -- messages-option may be one of the following:
1966 --
1967 -- DEFAULT (D) No messages are output if there is no error or warning.
1968 --
1969 -- MEDIUM A small number of messages are output.
1970 --
1971 -- HIGH A great number of messages are output, most of them not
1972 -- being useful for the user.
1976 -- /MULTI_UNIT_INDEX=nnn
1977 --
1978 -- Specify the index of the unit to compile in a multi-unit source file.
1982 -- /MAX_NESTING=nnn
1983 --
1984 -- Set maximum level of nesting of constructs (including subprograms,
1985 -- loops, blocks, packages, and conditionals).
1986 -- The level of nesting must not exceed the given value nnn.
1987 -- A value of zero disable this style check (not enabled by default).
1991 -- /NO_GNAT_ADC
1992 --
1993 -- Cause the compiler to ignore any configuration pragmas file GNAT.ADC
1994 -- in the default directory. Implied by qualifier /PROJECT_FILE.
1995 -- Often used in conjunction with qualifier /CONFIGURATION_PRAGMAS_FILE.
1999 -- /NOLOAD
2000 --
2001 -- Cause the compiler to operate in semantic check mode with full
2002 -- checking for all illegalities specified in the reference manual, but
2003 -- without generation of any source code (no object or ALI file
2004 -- generated).
2005 --
2006 -- Since dependent files must be accessed, you must follow the GNAT
2007 -- semantic restrictions on file structuring to operate in this mode:
2008 --
2009 -- o The needed source files must be accessible.
2010 -- o Each file must contain only one compilation unit.
2011 -- o The file name and unit name must match.
2012 --
2013 -- The output consists of error messages as appropriate. No object file
2014 -- or ALI file is generated. The checking corresponds exactly to the
2015 -- notion of legality in the Ada reference manual.
2016 --
2017 -- Any unit can be compiled in semantics-checking-only mode, including
2018 -- units that would not normally be compiled (generic library units,
2019 -- subunits, and specifications where a separate body is present).
2023 -- /NOSTD_INCLUDES

2025 -- Do not look in the default directory for source files of the runtime.
2029 -- /NOSTD_LIBRARIES

2031 -- Do not look for library files in the system default directory.
2035 -- /NOWARNING_PRAGMAS
2036 --
2037 -- Causes all Warnings pragmas to be ignored. Useful to check if the
2038 -- program has obsolete warnings pragmas that are hiding problems.
2057 -- /NOOPTIMIZE (D)
2058 -- /OPTIMIZE[=(keyword[,...])]
2059 --
2060 -- Selects the level of optimization for your program. The supported
2061 -- keywords are as follows:
2062 --
2063 -- ALL (D) Perform most optimizations, including those that
2064 -- may be expensive.
2065 --
2066 -- NONE Do not do any optimizations. Same as /NOOPTIMIZE.
2067 --
2068 -- SOME Perform some optimizations, but omit ones that
2069 -- are costly in compilation time.
2070 --
2071 -- SPACE Optimize space usage
2072 --
2073 -- DEVELOPMENT Same as SOME.
2074 --
2075 -- INLINING Full optimization, and also attempt automatic inlining
2076 -- of small subprograms within a unit
2077 --
2078 -- UNROLL_LOOPS Try to unroll loops. This keyword may be specified
2079 -- with any keyword above other than NONE. Loop
2080 -- unrolling usually, but not always, improves the
2081 -- performance of programs.
2082 --
2083 -- NO_STRICT_ALIASING
2084 -- Suppress aliasing analysis. When optimization is
2085 -- enabled (ALL or SOME above), the compiler assumes
2086 -- that pointers do in fact point to legitimate values
2087 -- of the pointer type (allocated from the proper pool).
2088 -- If this assumption is violated, e.g. by the use of
2089 -- unchecked conversion, then it may be necessary to
2090 -- suppress this assumption using this keyword (which
2091 -- may be specified only in conjunction with any
2092 -- keyword above, other than NONE).
2096 -- NODOC (see /OPTIMIZE)
2100 -- /OUTPUT_FILE=fname
2101 --
2102 -- This has the same effect as /LIST except that the output is written
2103 -- to a file instead of to standard output. If the given fname
2104 -- does not start with a period, then it is the full name of the file
2105 -- to be written. If fname starts with a period, the name of the file
2106 -- is the concatenation of to the name of the file being compiled with
2107 -- fname where the period is replace by an underline. For example, if
2108 -- file xyz.adb is compiled with -gnatl=.lst, then the output is written
2109 -- to file xyz.adb_lst.
2120 -- /POINTER_SIZE=64 (D)
2121 -- /POINTER_SIZE[=(keyword[,...])]

2128 -- Convention_C and generate 64bit descriptors for
2129 -- Descriptor mechanisms for calling imported
2130 -- subprograms and accept both 64bit and 32bit
2131 -- descriptors for calls to exported subprograms.
2132 --
2133 -- LONG Equivalent to option 64.
2134 --
2135 -- 32 Allocate all heap pointers in 32bit space and
2136 -- generate 32bit descriptors for Descriptor
2137 -- mechanisms for calling imported subprograms.
2138 --
2139 -- SHORT Equivalent to option 32.
2143 -- /NOPOLLING (D)
2144 -- /POLLING
2145 --
2146 -- Enable polling. See the description of pragma Polling in the GNAT
2147 -- Reference Manual for full details.
2151 -- /PROJECT_FILE=filename
2152 --
2153 -- Specifies the main project file to be used. The project files rooted
2154 -- at the main project file will be parsed before the invocation of the
2155 -- compiler. The source and object directories to be searched will be
2156 -- communicated to the compiler through logical names
2157 -- ADA_PRJ_INCLUDE_FILE and ADA_PRJ_OBJECTS_FILE.
2161 -- /PRINT_STANDARD
2162 --
2163 -- cause the compiler to output a representation of package Standard
2164 -- in a form very close to standard Ada. It is not quite possible to
2165 -- do this and remain entirely Standard (since new numeric base types
2166 -- cannot be created in standard Ada), but the output is easily
2167 -- readable to any Ada programmer, and is useful to determine the
2168 -- characteristics of target dependent types in package Standard.
2173 -- /NO_TREAT_RESTRICTIONS_AS_WARNINGS (D)
2174 -- /TREAT_RESTRICTIONS_AS_WARNINGS
2175 --
2176 -- Causes all restrictions to be treated as warnings (pragma Restriction
2177 -- treated as Restriction_Warnings, pragma Profile as Profile_Warnings,
2178 -- and pragma Ravenscar sets restriction warnings instead of restrictions)
2191 -- /NOREPORT_ERRORS (D)
2192 -- /REPORT_ERRORS[=(keyword[,...])]
2193 --
2194 -- Change the way errors are reported. The following keywords are
2195 -- supported:
2196 --
2197 -- VERBOSE (D) Verbose mode. Full error output with source lines
2198 -- to SYS$OUTPUT.
2199 --
2200 -- BRIEF Generate the brief format error messages to
2201 -- SYS$OUTPUT as well as the verbose format message or
2202 -- full listing.
2203 --
2204 -- FULL Normally, the compiler suppresses error messages that
2205 -- are likely to be redundant. This keyword causes all
2206 -- error messages to be generated. One particular effect
2207 -- is for the case of references to undefined variables.
2208 -- If a given variable is referenced several times, the
2209 -- normal format of messages produces one error. With
2210 -- FULL, each undefined reference produces a separate
2211 -- error message.
2212 --
2213 -- IMMEDIATE Normally, the compiler saves up error messages and
2214 -- generates them at the end of compilation in proper
2215 -- sequence. This keyword causes error messages to be
2216 -- generated as soon as they are detected. The use of
2217 -- IMMEDIATE usually causes error messages to be
2218 -- generated out of sequence. Use it when the compiler
2219 -- blows up due to an internal error. In this case, the
2220 -- error messages may be lost. Sometimes blowups are

2441 -- /STYLE_CHECKS[=(keyword,[...])]
2442 --
2443 -- Normally, GNAT permits any code layout consistent with the reference

2445 -- input source code. The following keywords are supported:
2446 --

2449 -- HTABS, IF_THEN, KEYWORD, LAYOUT, LINE_LENGTH,
2450 -- PRAGMA, REFERENCES, SPECS, TOKEN.
2451 --
2452 -- 1 .. 9 Specify indentation level from 1 to 9.
2453 -- The general style of required indentation is as
2454 -- specified by the examples in the Ada Reference
2455 -- Manual. Full line comments must be aligned with
2456 -- the -- starting on a column that is a multiple
2457 -- of the alignment level.
2458 --
2459 -- ATTRIBUTE Check attribute casing.
2460 -- Attribute names, including the case of keywords
2461 -- such as digits used as attributes names,
2462 -- must be written in mixed case, that is,
2463 -- the initial letter and any letter following an
2464 -- underscore must be uppercase.
2465 -- All other letters must be lowercase.
2466 --
2467 -- ARRAY_INDEXES Check indexes of array attributes.
2468 -- For array attributes First, Last, Range,
2469 -- or Length, the index number must be omitted
2470 -- for one-dimensional arrays and is required
2471 -- for multi-dimensional arrays.
2472 --
2473 -- BLANKS Blanks not allowed at statement end.
2474 -- Trailing blanks are not allowed at the end of
2475 -- statements. The purpose of this rule, together

2477 -- enforce a canonical format for the use of
2478 -- blanks to separate source tokens.
2479 --
2480 -- COMMENTS2 Check comments.
2481 -- COMMENTS Comments must meet the following set of rules:
2482 --
2483 -- * The "--" that starts the column must either
2484 -- start in column one, or else at least one
2485 -- blank must precede this sequence.
2486 --
2487 -- * Comments that follow other tokens on a line
2488 -- must have at least one blank following the
2489 -- "--" at the start of the comment.
2490 --
2491 -- * Full line comments must have two blanks
2492 -- following the "--" that starts the comment,
2493 -- with the following exceptions.
2494 --
2495 -- * A line consisting only of the "--"
2496 -- characters, possibly preceded by blanks is
2497 -- permitted.
2498 --
2499 -- * A comment starting with "--x" where x is
2500 -- a special character is permitted. This
2501 -- allows proper processing of the output
2502 -- generated by specialized tools including
2503 -- gnatprep (where --! is used) and the SPARK
2504 -- annotation language (where --# is used).
2505 -- For the purposes of this rule, a special
2506 -- character is defined as being in one of the
2507 -- ASCII ranges 16#21#..16#2F# or
2508 -- 16#3A#..16#3F#.
2509 --
2510 -- * A line consisting entirely of minus signs,
2511 -- possibly preceded by blanks, is permitted.
2512 -- This allows the construction of box
2513 -- comments where lines of minus signs are
2514 -- used to form the top and bottom of the box.
2515 --
2516 -- * If a comment starts and ends with "--" is
2517 -- permitted as long as at least one blank
2518 -- follows the initial "--". Together with
2519 -- the preceding rule, this allows the
2520 -- construction of box comments, as shown in
2521 -- the following example:
2522 --
2523 -- ---------------------------
2524 -- -- This is a box comment --
2525 -- ---------------------------
2526 --
2527 -- COMMENTS1 Check comments (single space).
2528 -- Like COMMENTS2, but the -- of a comment only
2529 -- requires one or more spaces following, instead
2530 -- of two or more spaces.
2531 --
2532 -- DOS_LINE_ENDINGS Check that no DOS line terminators are present
2533 -- All lines must be terminated by a single
2534 -- ASCII.LF character. In particular the DOS line
2535 -- terminator sequence CR / LF is not allowed).
2536 --
2537 -- END Check end/exit labels.
2538 -- Optional labels on end statements ending
2539 -- subprograms and on exit statements exiting
2540 -- named loops, are required to be present.
2541 --
2542 -- GNAT Enforces a set of style conventions that
2543 -- match the style used in the GNAT source code.
2544 -- This maybe useful when developing code that
2545 -- is eventually intended to be incorporated into
2546 -- GNAT. For further details, see GNAT sources.
2547 --
2548 -- HTABS No horizontal tabs.
2549 -- Horizontal tab characters are not permitted in
2550 -- the source text. Together with the BLANKS
2551 -- (no blanks at end of line) option, this
2552 -- enforces a canonical form for the use of blanks
2553 -- to separate source tokens.
2554 --
2555 -- IF_THEN Check if-then layout.
2556 -- The keyword then must appear either on the
2557 -- same line as the corresponding if, or on a line
2558 -- on its own, lined up under the if with at least
2559 -- one non-blank line in between containing all or
2560 -- part of the condition to be tested.
2561 --
2562 -- KEYWORD Check keyword casing.
2563 -- All keywords must be in lower case (with the
2564 -- exception of keywords such as digits used as
2565 -- attribute names to which this check does not
2566 -- apply).
2567 --
2568 -- LAYOUT Check layout.
2569 -- Layout of statement and declaration constructs
2570 -- must follow the recommendations in the Ada
2571 -- Reference Manual, as indicated by the form of
2572 -- the syntax rules. For example an else keyword
2573 -- must be lined up with the corresponding if
2574 -- keyword.
2575 --
2576 -- There are two respects in which the style rule
2577 -- enforced by this check option are more liberal
2578 -- than those in the Ada Reference Manual.
2579 -- First in the case of record declarations,
2580 -- it is permissible to put the record keyword on
2581 -- the same line as the type keyword, and then
2582 -- the end in end record must line up under type.
2583 -- For example, either of the following two
2584 -- layouts is acceptable:
2585 --
2586 -- type q is record
2587 -- a : integer;
2588 -- b : integer;
2589 -- end record;
2590 --
2591 -- type q is
2592 -- record
2593 -- a : integer;
2594 -- b : integer;
2595 -- end record;
2596 --
2597 -- Second, in the case of a block statement,
2598 -- a permitted alternative is to put the block
2599 -- label on the same line as the declare or begin
2600 -- keyword, and then line the end keyword up under
2601 -- the block label. For example both the following
2602 -- are permitted:
2603 --
2604 --
2605 --
2606 -- Block : declare
2607 -- A : Integer := 3;
2608 -- begin
2609 -- Proc (A, A);
2610 -- end Block;
2611 --
2612 -- Block :
2613 -- declare
2614 -- A : Integer := 3;
2615 -- begin
2616 -- Proc (A, A);
2617 -- end Block;
2618 --
2619 -- The same alternative format is allowed for
2620 -- loops. For example, both of the following are
2621 -- permitted:
2622 --
2623 --
2624 --
2625 -- Clear : while J < 10 loop
2626 -- A (J) := 0;
2627 -- end loop Clear;
2628 --
2629 -- Clear :
2630 -- while J < 10 loop
2631 -- A (J) := 0;
2632 -- end loop Clear;
2633 --
2634 --
2635 --
2636 -- LINE_LENGTH Check maximum line length.
2637 -- The length of source lines must not exceed 79
2638 -- characters, including any trailing blanks
2639 -- The value of 79 allows convenient display on
2640 -- an 80 character wide device or window, allowing
2641 -- for possible special treatment of 80 character
2642 -- lines.
2643 --
2644 -- NONE Clear any previously set style checks.
2645 --
2646 -- ORDERED_SUBPROGRAMS Check order of subprogram bodies.
2647 -- All subprogram bodies in a given scope (e.g.
2648 -- a package body) must be in alphabetical order.
2649 -- The ordering rule uses normal Ada rules for
2650 -- comparing strings, ignoring casing of letters,
2651 -- except that if there is a trailing numeric
2652 -- suffix, then the value of this suffix is used
2653 -- in the ordering (e.g. Junk2 comes before
2654 -- Junk10).
2655 --
2656 -- OVERRIDING_INDICATORS Check that overriding subprograms are
2657 -- explicitly marked as such. The declaration of
2658 -- a primitive operation of a type extension that
2659 -- overrides an inherited operation must carry
2660 -- an overriding indicator.
2661 --
2662 -- PRAGMA Check pragma casing.
2663 -- Pragma names must be written in mixed case,
2664 -- that is, the initial letter and any letter
2665 -- following an underscore must be uppercase.
2666 -- All other letters must be lowercase.
2667 --
2668 -- REFERENCES Check references.
2669 -- All identifier references must be cased in the
2670 -- same way as the corresponding declaration.
2671 -- No specific casing style is imposed on
2672 -- identifiers. The only requirement is for
2673 -- consistency of references with declarations.
2674 --
2675 -- SPECS Check separate specs.
2676 -- Separate declarations ("specs") are required
2677 -- for subprograms (a body is not allowed to serve
2678 -- as its own declaration). The only exception is
2679 -- that parameterless library level procedures are
2680 -- not required to have a separate declaration.
2681 -- This exception covers the most frequent form of
2682 -- main program procedures.
2683 --
2684 -- STANDARD_CASING Check casing of entities in Standard.
2685 -- Any identifier from Standard must be cased to
2686 -- match the presentation in the Ada Reference
2687 -- Manual (for example, Integer and ASCII.NUL).
2688 --
2689 -- TOKEN Check token spacing.
2690 -- The following token spacing rules are enforced:
2691 --
2692 -- * The keywords abs and not must be followed
2693 -- by a space.
2694 --
2695 -- * The token => must be surrounded by spaces.
2696 --
2697 -- * The token <> must be preceded by a space or
2698 -- a left parenthesis.
2699 --
2700 -- * Binary operators other than ** must be
2701 -- surrounded by spaces. There is no
2702 -- restriction on the layout of the ** binary
2703 -- operator.
2704 --
2705 -- * Colon must be surrounded by spaces.
2706 --
2707 -- * Colon-equal (assignment) must be surrounded
2708 -- by spaces.
2709 --
2710 -- * Comma must be the first non-blank character
2711 -- on the line, or be immediately preceded by
2712 -- a non-blank character, and must be followed
2713 -- by a space.
2714 --
2715 -- * If the token preceding a left paren ends
2716 -- with a letter or digit, then a space must
2717 -- separate the two tokens.
2718 --
2719 -- * A right parenthesis must either be the
2720 -- first non-blank character on a line, or it
2721 -- must be preceded by a non-blank character.
2722 --
2723 -- * A semicolon must not be preceded by
2724 -- a space, and must not be followed by
2725 -- a non-blank character.
2726 --
2727 -- * A unary plus or minus may not be followed
2728 -- by a space.
2729 --
2730 -- * A vertical bar must be surrounded by
2731 -- spaces.
2732 --
2733 -- In the above rules, appearing in column one is
2734 -- always permitted, that is, counts as meeting
2735 -- either a requirement for a required preceding
2736 -- space, or as meeting a requirement for no
2737 -- preceding space.
2738 --
2739 -- Appearing at the end of a line is also always
2740 -- permitted, that is, counts as meeting either
2741 -- a requirement for a following space,
2742 -- or as meeting a requirement for no following
2743 -- space.
2744 --
2745 -- UNNECESSARY_BLANK_LINES
2746 -- Check for unnecessary blank lines.
2747 -- A blank line is considered unnecessary if it
2748 -- appears at the end of the file, or if more
2749 -- than one blank line occurs in sequence.
2750 --
2751 -- VTABS No form feeds or vertical tabs.
2752 -- Form feeds or vertical tab characters are not
2753 -- permitted in the source text.
2754 --
2755 -- XTRA_PARENS Check for the use of an unnecessary extra
2756 -- level of parentheses (C - style) around
2757 -- conditions in if statements, while statements
2758 -- and exit statements.
2762 -- NODOC (see /STYLE_CHECKS)
2766 -- /SUBDIRS=dir
2767 --
2768 -- The actual directories (object, exec, library, ...) are subdirectories
2769 -- of the directory specified in the project file. If the subdirectory
2770 -- does not exist, it is created automatically.
2774 -- /SYMBOL_PREPROCESSING="symbol=value"
2775 --
2776 -- Define or redefine a preprocessing symbol, associated with value.
2777 -- If "=value" is not specified, then the value of the symbol is True.
2778 -- A symbol is an identifier, following normal Ada (case-insensitive)
2779 -- rules for its syntax, and value is any sequence (including an empty
2780 -- sequence) of characters from the set (letters, digits, period,
2781 -- underline). Ada reserved words may be used as symbols, with the
2782 -- exceptions of "if", "else", "elsif", "end", "and", "or" and "then".
2783 --
2784 -- A symbol declared with this qualifier on the command line replaces
2785 -- a symbol with the same name either in a definition file or specified
2786 -- with a switch -D in the preprocessor data file.
2787 --
2788 -- This qualifier is similar to qualifier /ASSOCIATE of
2789 -- GNAT PREPROCESSING.
2793 -- /NOSYNTAX_ONLY (D)
2794 -- /SYNTAX_ONLY
2795 --
2796 -- Run GNAT in syntax checking only mode. You can check a series of
2797 -- files in a single command, and can use wild cards to specify such a
2798 -- group of files.
2799 --
2800 -- You may use other qualifiers in conjunction with this qualifier. In
2801 -- particular, /LIST and /REPORT_ERRORS=VERBOSE are useful to control the
2802 -- format of any generated error messages.
2803 --
2804 -- The output is simply the error messages, if any. No object file or ALI
2805 -- file is generated by a syntax-only compilation. Also, no units other
2806 -- than the one specified are accessed. For example, if a unit "X" with's
2807 -- a unit "Y", compiling unit "X" in syntax check only mode does not
2808 -- access the source file containing unit "Y".
2809 --
2810 -- Normally, GNAT allows only a single unit in a source file. However,
2811 -- this restriction does not apply in syntax-check-only mode, and it is
2812 -- possible to check a file containing multiple compilation units
2813 -- concatenated together. This is primarily used by the GNAT CHOP
2814 -- command.
2818 -- /TABLE_MULTIPLIER=nnn

2829 -- unit or nested unit, as it is being analyzed.
2833 -- /TREE_OUTPUT
2834 -- /NOTREE_OUTPUT
2835 --
2836 -- Cause GNAT to write the internal tree for a unit to a file (with the
2837 -- filetype ATB for a body or ATS for a spec). This is not normally
2838 -- required, but is used by separate analysis tools. Typically these
2839 -- tools do the necessary compilations automatically, so you should never
2840 -- have to specify this switch in normal operation.
2844 -- /TRY_SEMANTICS
2845 -- /NOTRY_SEMANTICS
2846 --
2847 -- In normal operation mode the compiler first parses the program and
2848 -- determines if there are any syntax errors. If there are, appropriate
2849 -- error messages are generated and compilation is immediately
2850 -- terminated. This qualifier tells GNAT to continue with semantic
2851 -- analysis even if syntax errors have been found. This may enable the
2852 -- detection of more errors in a single run. On the other hand, the
2853 -- semantic analyzer is more likely to encounter some internal fatal

2942 -- Notably extra checks may be needed for case
2943 -- statements and subscripted array assignments.
2944 --
2945 -- NONE No special checks for invalid values are
2946 -- performed. This means that references to
2947 -- uninitialized variables can cause erroneous

3200 -- The use of a prefix of an access type in an
3201 -- indexed component, slice, or selected component
3202 -- without an explicit .all will generate
3203 -- a warning. With this warning enabled, access
3204 -- checks occur only at points where an explicit
3205 -- .all appears in the source code (assuming no
3206 -- warnings are generated as a result of this

3208 -- not generated. Note that /WARNINGS=ALL does not
3209 -- affect the setting of this warning option.
3210 --
3211 -- NOIMPLICIT_DEREFERENCE Suppress warnings on implicit dereferencing.
3212 -- in indexed components, slices, and selected
3213 -- components.

3220 -- Elaborate_All statements.
3221 --
3222 -- ERRORS Warning messages are to be treated as errors.
3223 -- The warning string still appears, but the
3224 -- warning messages are counted as errors, and
3225 -- prevent the generation of an object file.
3226 --
3227 -- HIDING Activate warnings on hiding declarations.
3228 -- A declaration is considered hiding if it is
3229 -- for a non-overloadable entity, and it declares
3230 -- an entity with the same name as some other

3232 -- default is that such warnings are not
3233 -- generated.
3234 --
3235 -- NOHIDING Suppress warnings on hiding declarations.
3236 --
3237 -- IMPLEMENTATION Activate warnings for a with of an internal
3238 -- GNAT implementation unit, defined as any unit
3239 -- from the Ada, Interfaces, GNAT, DEC or
3240 -- System hierarchies that is not documented in
3241 -- either the Ada Reference Manual or the GNAT
3242 -- Programmer's Reference Manual. Such units are
3243 -- intended only for internal implementation
3244 -- purposes and should not be with'ed by user
3245 -- programs. The default is that such warnings
3246 -- are generated.
3247 --
3248 -- NOIMPLEMENTATION Disables warnings for a with of an internal
3249 -- GNAT implementation unit.
3250 --
3251 -- INEFFECTIVE_INLINE Activate warnings on ineffective pragma Inlines
3252 -- Activates warnings for failure of front end
3253 -- inlining (activated by /INLINE=FULL) to inline
3254 -- a particular call. There are many reasons for
3255 -- not being able to inline a call, including most
3256 -- commonly that the call is too complex to
3257 -- inline. This warning can also be turned on
3258 -- using /INLINE=FULL.
3259 --
3260 -- NOINEFFECTIVE_INLINE Suppress warnings on ineffective pragma Inlines
3261 -- Suppresses warnings on ineffective pragma
3262 -- Inlines. If the inlining mechanism cannot
3263 -- inline a call, it will simply ignore the
3264 -- request silently.
3265 --
3266 -- MISSING_COMPONENT_CLAUSES
3267 -- Activate warnings for cases when there are
3268 -- component clauses for a record type, but not
3269 -- for every component of the record.

3272 -- Suppress warnings for cases when there are
3273 -- missing component clauses for a record type.
3274 --
3275 -- MISSING_PARENS
3276 -- Activate warnings for cases where parentheses
3277 -- are not used and the result is potential
3278 -- ambiguity from a reader's point of view.
3279 -- For example (not a > b) when a and b are
3280 -- modular means (not (a) > b) and very likely
3281 -- the programmer intended (not (a > b)).
3282 --
3283 -- NOMISSING_PARENS
3284 -- Suppress warnings for cases where parentheses
3285 -- are not used and the result is potential
3286 -- ambiguity from a reader's point of view.
3287 --
3288 -- MODIFIED_UNREF Activates warnings for variables that are
3289 -- assigned (using an initialization value or with
3290 -- one or more assignment statements) but whose
3291 -- value is never read. The warning is suppressed
3292 -- for volatile variables and also for variables
3293 -- that are renamings of other variables or for
3294 -- which an address clause is given. This warning
3295 -- can also be turned on using /WARNINGS/OPTIONAL.
3296 --
3297 -- NOMODIFIED_UNREF Disables warnings for variables that are
3298 -- assigned or initialized, but never read.
3299 --
3300 -- NORMAL Sets normal warning mode, in which enabled
3301 -- warnings are issued and treated as warnings
3302 -- rather than errors. This is the default mode.
3303 -- It can be used to cancel the effect of an
3304 -- explicit /WARNINGS=SUPPRESS or
3305 -- /WARNINGS=ERRORS. It also cancels the effect
3306 -- of the implicit /WARNINGS=ERRORS that is
3307 -- activated by the use of /STYLE=GNAT.
3308 --
3309 -- OBSOLESCENT Activates warnings for calls to subprograms
3310 -- marked with pragma Obsolescent and for use of
3311 -- features in Annex J of the Ada Reference
3312 -- Manual. In the case of Annex J, not all
3313 -- features are flagged. In particular use of the
3314 -- renamed packages (like Text_IO), use of package
3315 -- ASCII and use of the attribute 'Constrained are
3316 -- not flagged, since these are very common and
3317 -- would generate many annoying positive warnings.
3318 -- The default is that such warnings are not
3319 -- generated.
3320 --
3321 -- NOOBSOLESCENT Disables warnings on use of obsolescent
3322 -- features.
3323 --
3324 -- OBJECT_RENAME Activate warnings for non limited objects
3325 -- renaming parameterless functions.
3326 --

3332 -- NOOPTIONAL Equivalent to NOALL.
3333 --
3334 -- OVERLAYS Activate warnings for possibly unintended

3336 -- clauses that cause one variable to overlap
3337 -- another. The default is that such warnings
3338 -- are generated.
3339 --
3340 -- NOOVERLAYS Suppress warnings on possibly unintended
3341 -- initialization effects of defining address
3342 -- clauses that cause one variable to overlap
3343 -- another.
3344 --
3345 -- REDUNDANT Activate warnings for redundant constructs.
3346 -- In particular assignments of a variable to
3347 -- itself, and a type conversion that converts
3348 -- an object to its own type. The default
3349 -- is that such warnings are not generated.
3350 --
3351 -- NOREDUNDANT Suppress warnings for redundant constructs.
3352 --
3353 -- SUPPRESS Completely suppress the output of all warning
3354 -- messages. Same as /NOWARNINGS.
3355 --
3356 -- UNCHECKED_CONVERSIONS Activates warnings on unchecked conversions.
3357 -- Causes warnings to be generated for
3358 -- unchecked conversions when the two types are
3359 -- known at compile time to have different sizes.
3360 -- The default is that such warnings are

3362 --
3363 -- NOUNCHECKED_CONVERSIONS Suppress warnings for unchecked conversions.
3364 --
3365 -- UNINITIALIZED Generate warnings for uninitialized variables.
3366 -- This is a GCC option, not an Ada option.
3367 -- You must also specify the /OPTIMIZE qualifier
3368 -- with a value other than NONE (in other words,
3369 -- this keyword works only if optimization is
3370 -- turned on).
3371 --
3372 -- UNREFERENCED_FORMALS Activate warnings on unreferenced formals.
3373 -- Causes a warning to be generated if a formal
3374 -- parameter is not referenced in the body of
3375 -- the subprogram. This warning can also be turned
3376 -- on using option ALL or UNUSED.
3377 --
3378 -- NOUNREFERENCED_FORMALS Suppress warnings on unreferenced formals.
3379 -- Suppresses warnings for unreferenced formal
3380 -- parameters. Note that the combination UNUSED
3381 -- followed by NOUNREFERENCED_FORMALS has the
3382 -- effect of warning on unreferenced entities
3383 -- other than subprogram formals.
3384 --
3385 -- UNUSED Activates warnings to be generated for entities
3386 -- that are defined but not referenced, and for
3387 -- units that are with'ed and not referenced. In
3388 -- the case of packages, a warning is also
3389 -- generated if no entities in the package are
3390 -- referenced. This means that if the package
3391 -- is referenced but the only references are in
3392 -- use clauses or renames declarations, a warning
3393 -- is still generated. A warning is also generated
3394 -- for a generic package that is with'ed but never
3395 -- instantiated. In the case where a package or
3396 -- subprogram body is compiled, and there is a
3397 -- with on the corresponding spec that is only
3398 -- referenced in the body, a warning is also
3399 -- generated, noting that the with can be moved
3400 -- to the body. The default is that such warnings
3401 -- are not generated.
3402 --
3403 -- NOUNUSED Suppress warnings for unused entities and
3404 -- packages.
3405 --
3406 -- VARIABLES_UNINITIALIZED Activates warnings on unassigned variables.
3407 -- Causes warnings to be generated when a variable

3418 -- NODOC (see /WARNINGS)
3422 -- /NO_BACK_END_WARNINGS
3423 --
3424 -- Inhibit all warning messages of the GCC back-end.
3439 -- /NOWIDE_CHARACTER_ENCODING (D)
3440 -- /WIDE_CHARACTER_ENCODING[=encode-type]
3441 --
3442 -- Specifies the mechanism used to encode wide characters. 'encode-type'
3443 -- is one of the following:
3444 --
3445 -- BRACKETS (D) A wide character is encoded as ["xxxx"] where XXXX
3446 -- are four hexadecimal digits representing the coding
3447 -- ('Pos value) of the character in type
3448 -- Wide_Character. The hexadecimal digits may use upper
3449 -- or lower case letters.
3450 --
3451 -- This notation can also be used for upper half
3452 -- Character values using the format ["xx"] where XX is
3453 -- two hexadecimal digits representing the coding ('Pos
3454 -- value) of the character in type Character (or
3455 -- Wide_Character). The hexadecimal digits may use upper
3456 -- of lower case.
3457 --
3458 -- NONE No wide characters are allowed. Same
3459 -- as /NOWIDE_CHARACTER_ENCODING.
3460 --
3461 -- HEX In this encoding, a wide character is represented by
3462 -- the following five character sequence: ESC a b c d
3463 -- Where 'a', 'b', 'c', and 'd' are the four hexadecimal
3464 -- characters (using uppercase letters) of the wide
3465 -- character code. For example, ESC A345 is used to
3466 -- represent the wide character with code 16#A345#. This
3467 -- scheme is compatible with use of the full
3468 -- Wide_Character set.
3469 --
3470 -- UPPER The wide character with encoding 16#abcd# where the
3471 -- upper bit is on (in other words, "a" is in the range
3472 -- 8-F) is represented as two bytes, 16#ab# and 16#cd#.
3473 -- The second byte may never be a format control
3474 -- character, but is not required to be in the upper
3475 -- half. This method can be also used for shift-JIS or
3476 -- EUC, where the internal coding matches the external
3477 -- coding.
3478 --
3479 -- SHIFT_JIS A wide character is represented by a two-character
3480 -- sequence, 16#ab# and 16#cd#, with the restrictions
3481 -- described for upper-half encoding as described above.
3482 -- The internal character code is the corresponding JIS
3483 -- character according to the standard algorithm for
3484 -- Shift-JIS conversion. Only characters defined in the
3485 -- JIS code set table can be used with this encoding
3486 -- method.
3487 --
3488 -- UTF8 A wide character is represented using
3489 -- UCS Transformation Format 8 (UTF-8) as defined in Annex
3490 -- R of ISO 10646-1/Am.2. Depending on the character
3491 -- value, the representation is a one, two, or three byte
3492 -- sequence:
3493 --
3494 -- 16#0000#-16#007f#: 2#0xxxxxxx#
3495 -- 16#0080#-16#07ff#: 2#110xxxxx# 2#10xxxxxx#
3496 -- 16#0800#-16#ffff#: 2#1110xxxx# 2#10xxxxxx# 2#10xxxxxx#
3497 --
3498 -- where the xxx bits correspond to the left-padded bits
3499 -- of the 16-bit character value. Note that all lower
3500 -- half ASCII characters are represented as ASCII bytes
3501 -- and all upper half characters and other wide characters
3502 -- are represented as sequences of upper-half (The full
3503 -- UTF-8 scheme allows for encoding 31-bit characters as
3504 -- 6-byte sequences, but in this implementation, all UTF-8
3505 -- sequences of four or more bytes length will be treated
3506 -- as illegal).
3507 --
3508 -- EUC A wide character is represented by a two-character
3509 -- sequence 16#ab# and 16#cd#, with both characters being
3510 -- in the upper half. The internal character code is the
3511 -- corresponding JIS character according to the EUC
3512 -- encoding algorithm. Only characters defined in the JIS
3513 -- code set table can be used with this encoding method.
3517 -- NODOC (see /WIDE_CHARACTER_ENCODING)
3521 -- /NOXDEBUG (D)
3522 -- /XDEBUG
3523 --
3524 -- Output expanded source files for source level debugging.
3525 -- The expanded source (see /EXPAND_SOURCE) is written to files
3526 -- with names formed by appending "_DG" to the input file name,
3527 -- The debugging information generated by the /DEBUG qualifier will then
3528 -- refer to the generated file. This allows source level debugging using
3529 -- the generated code which is sometimes useful for complex code, for
3530 -- example to find out exactly which part of a complex construction
3531 -- raised an exception. The maximum line length for the output is 72.
3535 -- /LXDEBUG=nnn
3536 --
3537 -- Output expanded source files for source level debugging.
3538 -- The expanded source (see /EXPAND_SOURCE) is written to files
3539 -- with names formed by appending "_DG" to the input file name,
3540 -- The debugging information generated by the /DEBUG qualifier will then

3542 -- the generated code which is sometimes useful for complex code, for
3543 -- example to find out exactly which part of a complex construction
3544 -- raised an exception. The parameter is the maximum line length for
3545 -- the output.
3552 -- /XREF[=keyword]
3553 --
3554 -- Normally the compiler generates full cross-referencing information in
3555 -- the .ALI file. This information is used by a number of tools,
3556 -- including GNAT FIND and GNAT XREF.
3557 --
3558 -- GENERATE (D) Generate cross-referencing information.
3559 --
3560 -- SUPPRESS Suppress cross-referencing information.
3561 -- This saves some space and may slightly

4536 --
4537 -- GNAT MAKE default behavior is to check if the sources are up to date,
4538 -- compile those sources that are not up to date, bind the main source,
4539 -- then link the executable.
4540 --

4543 --
4544 -- o Compile
4545 -- o Bind
4546 -- o Link
4547 --
4548 --

4550 -- qualifier:
4551 --
4552 -- BIND Bind only. Can be combined with /ACTIONS=COMPILE
4553 -- to do compilation and binding, but no linking.
4554 -- Can be combined with /ACTIONS=LINK to do binding and
4555 -- linking. When not combined with /ACTIONS=COMPILE,
4556 -- all the units in the closure of the main program must
4557 -- have been previously compiled and must be up to date.
4558 --
4559 -- COMPILE Compile only. Do not perform binding, except when
4560 -- /ACTIONS=BIND is also specified. Do not perform
4561 -- linking, except if both /ACTIONS=BIND and /ACTIONS=LINK
4562 -- are also specified.
4563 --
4564 -- LINK Link only. Can be combined with /ACTIONS=BIND to do
4565 -- binding and linking. Linking will not be performed
4566 -- if combined with /ACTIONS=COMPILE but not with
4567 -- /ACTIONS=BIND\. When not combined with /ACTIONS=BIND
4568 -- all the units in the closure of the main program must
4569 -- have been previously compiled and must be up to date,
4570 -- and the main program need to have been bound.

4575 --
4576 -- Add directories to the project search path.
4580 -- /NOALL_FILES (D)
4581 -- /ALL_FILES
4582 --
4583 -- Consider all files in the make process, even the GNAT internal system
4584 -- files (for example, the predefined Ada library files). By default,
4585 -- GNAT MAKE does not check these files (however, if there is an
4586 -- installation problem, it will be caught when GNAT MAKE binds your
4587 -- program). You may have to specify this qualifier if you are working on
4588 -- GNAT itself. The vast majority of GNAT MAKE users never need to
4589 -- specify this switch. All GNAT internal files with will be compiled
4590 -- with /STYLE_CHECK=GNAT.
4594 -- /NOALL_PROJECTS (D)
4595 -- /ALL_PROJECTS
4596 --
4597 -- Implies /Unique.
4598 -- When used without project files, it is equivalent to /UNIQUE.

4607 --
4608 -- Any qualifiers specified after this qualifier other than

4610 -- passed to any GNAT BIND commands generated by GNAT MAKE.
4614 -- /BND_LNK_FULL_PROJECT
4615 --
4616 -- Bind and link all sources of a project, without any consideration
4617 -- to attribute Main, if there is one. This qualifier need to be
4618 -- used in conjunction with the /PROJECT_FILE= qualifier and cannot
4619 -- be used with a main subprogram on the command line or for
4620 -- a library project file. As the binder is invoked with the option
4621 -- meaning "No Ada main subprogram", the user must ensure that the
4622 -- proper options are specified to the linker. This qualifier is
4623 -- normally used when the main subprogram is in a foreign language
4624 -- such as C.
4628 -- /COMPILER_QUALIFIERS

4630 -- Any qualifiers specified after this qualifier other than
4631 -- /BINDER_QUALIFIERS, /LINKER_QUALIFIERS and /MAKE_QUALIFIERS will be
4632 -- passed to any GNAT COMPILE commands generated by GNAT MAKE.

4655 -- Look for source, library or object files in the default directory.

4660 -- /DEPENDENCIES_LIST
4661 --
4662 -- Check if all objects are up to date. If they are, output the object
4663 -- dependences to SYS$OUTPUT in a form that can be directly exploited in
4664 -- a Unix-style Makefile. By default, each source file is prefixed with
4665 -- its (relative or absolute) directory name. This name is whatever you
4666 -- specified in the various /SOURCE_SEARCH and /SEARCH qualifiers. If
4667 -- you also specify the /QUIET qualifier, only the source file names,
4668 -- without relative paths, are output. If you just specify the
4669 -- /DEPENDENCY_LIST qualifier, dependencies of the GNAT internal system
4670 -- files are omitted. This is typically what you want. If you also
4671 -- specify the /ALL_FILES qualifier, dependencies of the GNAT internal
4672 -- files are also listed. Note that dependencies of the objects in
4673 -- external Ada libraries (see the /SKIP_MISSING qualifier) are never

4688 -- Display progress for each source, up to date or not, as a single line
4689 -- completed x out of y (zz%)
4690 -- If the file needs to be compiled this is displayed after the
4691 -- invocation of the compiler. These lines are displayed even in quiet
4692 -- output mode (/QUIET).
4696 -- /NODO_OBJECT_CHECK (D)
4697 -- /DO_OBJECT_CHECK
4698 --
4699 -- Don't compile, bind, or link. Output a single command that will
4700 -- recompile an out of date unit, if any. Repeated use of this option,
4701 -- followed by carrying out the indicated compilation, will eventually
4702 -- result in recompiling all required units.
4703 --
4704 -- If any ALI is missing during the process, GNAT MAKE halts and
4705 -- displays an error message.
4709 -- /EXECUTABLE=exec-name
4710 --
4711 -- The name of the final executable program will be 'exec_name'. If this
4712 -- qualifier is omitted the default name for the executable will be the

4730 --
4731 -- Follow links when parsing project files
4735 -- /NOFORCE_COMPILE (D)
4736 -- /FORCE_COMPILE
4737 --
4738 -- Force recompilations. Recompile all sources, even though some object
4739 -- files may be up to date, but don't recompile predefined or GNAT
4740 -- internal files unless the /ALL_FILES qualifier is also specified.
4744 -- /NOFULL_PATH_IN_BRIEF_MESSAGES (D)
4745 -- /FULL_PATH_IN_BRIEF_MESSAGES
4746 --
4747 -- When using project files, if some errors or warnings are detected
4748 -- during parsing and verbose mode is not in effect (no use of qualifier
4749 -- /VERBOSE), then error lines start with the full path name of the
4750 -- project file, rather than its simple file name.
4754 -- /NOHIGH_VERBOSITY (D)
4755 -- /HIGH_VERBOSITY
4756 --
4757 -- Displays the reason for all recompilations GNAT MAKE decides are
4758 -- necessary, in high verbosity. Equivalent to /VERBOSE.
4762 -- /NOIN_PLACE (D)
4763 -- /IN_PLACE
4764 --
4765 -- In normal mode, GNAT MAKE compiles all object files and ALI files
4766 -- into the current directory. If the /IN_PLACE switch is used,
4767 -- then instead object files and ALI files that already exist are over-
4768 -- written in place. This means that once a large project is organized
4769 -- into separate directories in the desired manner, then GNAT MAKE will
4770 -- automatically maintain and update this organization. If no ALI files
4771 -- are found on the Ada object path, the new object and ALI files are
4772 -- created in the directory containing the source being compiled.
4776 -- /SOURCE_INDEX=nnn
4777 --
4778 -- Specifies the index of the units in the source file
4779 -- By default, source files are mono-unit and there is no index

4793 --
4794 -- Any qualifiers specified after this qualifier other than

4796 -- passed to any GNAT LINK commands generated by GNAT LINK.
4800 -- /NOLOW_VERBOSITY (D)
4801 -- /LOW_VERBOSITY
4802 --
4803 -- Displays the reason for all recompilations GNAT MAKE decides are

4810 --
4811 -- Any qualifiers specified after this qualifier other than
4812 -- /COMPILER_QUALIFIERS, /BINDER_QUALIFIERS and /LINKER_QUALIFIERS
4813 -- are for the benefit of GNAT MAKE itself.
4817 -- /NOMAPPING (D)
4818 -- /MAPPING
4819 --
4820 -- Use a mapping file. A mapping file is a way to communicate to the
4821 -- compiler two mappings: from unit names to file names (without any
4822 -- directory information) and from file names to path names (with full
4823 -- directory information). These mappings are used by the compiler to
4824 -- short-circuit the path search. When GNAT MAKE is invoked with this
4825 -- qualifier, it will create a mapping file, initially populated by the
4826 -- project manager, if /PROJECT_File= is used, otherwise initially empty.
4827 -- Each invocation of the compiler will add the newly accessed sources to
4828 -- the mapping file. This will improve the source search during the next
4829 -- invocations of the compiler
4833 -- /NOMEDIUM_VERBOSITY (D)
4834 -- /MEDIUM_VERBOSITY
4835 --
4836 -- Displays the reason for all recompilations GNAT MAKE decides are
4837 -- necessary, in medium verbosity, that is with potentially less output
4838 -- than /HIGH_VERBOSITY or /VERBOSE.
4847 -- /MESSAGES_PROJECT_FILE[=messages-option]
4848 --
4849 -- Specifies the "verbosity" of the parsing of project files.
4850 -- messages-option may be one of the following:
4851 --
4852 -- DEFAULT (D) No messages are output if there is no error or warning.
4853 --
4854 -- MEDIUM A small number of messages are output.
4855 --
4856 -- HIGH A great number of messages are output, most of them not
4857 -- being useful for the user.
4861 -- /NOMINIMAL_RECOMPILATION (D)
4862 -- /MINIMAL_RECOMPILATION
4863 --
4864 -- Specifies that the minimum necessary amount of recompilation
4865 -- be performed. In this mode GNAT MAKE ignores time stamp differences
4866 -- when the only modifications to a source file consist in
4867 -- adding/removing comments, empty lines, spaces or tabs.
4871 -- /NOCREATE_MISSING_DIRS (D)
4872 -- /CREATE_MISSING_DIRS
4873 --
4874 -- When an object directory, a library directory or an exec directory
4875 -- in missing, attempt to create the directory.
4879 -- /NOLINK
4880 --
4881 -- Compile only. Do not perform binding and linking. If the root unit is
4882 -- not a main unit, this is the default. Otherwise GNAT MAKE will
4883 -- attempt binding and linking unless all objects are up to date and the
4884 -- executable is more recent than the objects.
4885 -- This is equivalent to /ACTIONS=COMPILE
4889 -- /NOMAIN
4890 --
4891 -- No main subprogram. Bind and link the program even if the unit name
4892 -- given on the command line is a package name. The resulting executable
4893 -- will execute the elaboration routines of the package and its closure,
4894 -- then the finalization routines.
4898 -- /NON_PROJECT_UNIT_COMPILATION
4899 --
4900 -- Normally, when using project files, a unit that is not part of any
4901 -- project file, cannot be compile. These units may be compile, when
4902 -- needed, if this qualifier is specified.
4906 -- /NOSTD_INCLUDES
4907 --
4908 -- Do not look for sources the in the system default directory.
4912 -- /NOSTD_LIBRARIES
4913 --
4914 -- Do not look for library files in the system default directory.

4921 -- directories.
4925 -- /NOPROCESSES (D)
4926 -- /PROCESSES=NNN
4927 --
4928 -- Use NNN processes to carry out the (re)compilations. If you have a
4929 -- multiprocessor machine, compilations will occur in parallel. In the
4930 -- event of compilation errors, messages from various compilations might
4931 -- get interspersed (but GNAT MAKE will give you the full ordered list of
4932 -- failing compiles at the end). This can at times be annoying. To get a
4933 -- clean list of error messages don't use this qualifier.
4937 -- NODOC (see /PROCESS)
4941 -- /PROJECT_FILE=filename
4942 --
4943 -- Specifies the main project file to be used. The project files rooted
4944 -- at the main project file will be parsed before any other processing to
4945 -- set the building environment.
4949 -- /NOQUIET (D)
4950 -- /QUIET
4951 --
4952 -- When this qualifiers is specified, the commands carried out by GNAT
4953 -- MAKE are not displayed.

5006 --
5007 -- Output the commands for the compiler, the binder and the linker
5008 -- on SYS$OUTPUT, instead of SYS$ERROR.
5012 -- /SUBDIRS=dir
5013 --
5014 -- The actual directories (object, exec, library, ...) are subdirectories
5015 -- of the directory specified in the project file. If the subdirectory
5016 -- does not exist, it is created automatically.
5020 -- /NOSWITCH_CHECK (D)
5021 -- /SWITCH_CHECK
5022 --
5023 -- Recompile if compiler switches have changed since last compilation.
5024 -- All compiler switches but -I and -o are taken into account in the
5025 -- following way: orders between different "first letter" switches are
5026 -- ignored, but orders between same switches are taken into account.
5027 -- For example, -O -O2 is different than -O2 -O, but -g -O is equivalent
5028 -- to -O -g.
5032 -- /NOUNCHECKED_SHARED_LIB_IMPORTS (D)

5034 --
5035 -- Allow shared library projects to import static library projects
5039 -- /NOUNIQUE (D)
5040 -- /UNIQUE
5041 --
5042 -- Recompile at most the main file. It implies /ACTIONS=COMPILE.

5050 -- Use a specific mapping file. The file 'file_name', specified as a path
5051 -- name (absolute or relative) by this qualifier, should already exist,

7087 --
7088 -- MEDIUM A small number of messages are output.
7089 --
7090 -- HIGH A great number of messages are output, most of them not
7091 -- being useful for the user.
7095 -- /PROJECT_FILE=filename
7096 --
7097 -- Specifies the main project file to be used. The project files rooted
7098 -- at the main project file will be parsed before the invocation of the
7099 -- gnatcheck. The source directories to be searched will be communicated
7100 -- to gnatcheck through logical name ADA_PRJ_INCLUDE_FILE.

7106 --
7107 -- Work quietly, only output warnings and errors.
7111 -- /SUBDIRS=dir
7112 --
7113 -- The actual directories (object, exec, library, ...) are subdirectories

7120 -- /VERBOSE
7121 --
7122 -- The version number and copyright notice are output, as well as exact

7194 -- /ADD_PROJECT_SEARCH_PATH=(directory[,...])
7195 --
7196 -- Add directories to the project search path.
7200 -- /NOALL_FILES (D)
7201 -- /ALL_FILES
7202 --
7203 -- If this switch is present, FIND and XREF will parse the read-only
7204 -- files found in the library search path. Otherwise, these files will
7205 -- be ignored. This option can be used to protect Gnat sources or your
7206 -- own libraries from being parsed, thus making FIND and XREF much
7207 -- faster, and their output much smaller.
7211 -- /NODERIVED_TYPES (D)
7212 -- /DERIVED_TYPES
7213 --
7214 -- Output the parent type reference for each matching derived types.
7218 -- /EXTERNAL_REFERENCE="name=val"
7219 --
7220 -- Specifies an external reference to the project manager. Useful only if
7221 -- /PROJECT_FILE is used.

7236 -- /FULL_PATHNAME
7237 --
7238 -- If this switch is set, the output file names will be preceded by their
7239 -- directory (if the file was found in the search path). If this switch
7240 -- is not set, the directory will not be printed.
7244 -- /NOIGNORE_LOCALS (D)
7245 -- /IGNORE_LOCALS
7246 --
7247 -- If this switch is set, information is output only for library-level
7248 -- entities, ignoring local entities. The use of this switch may
7249 -- accelerate FIND and XREF.
7258 -- /MESSAGES_PROJECT_FILE[=messages-option]
7259 --
7260 -- Specifies the "verbosity" of the parsing of project files.
7261 -- messages-option may be one of the following:

7264 --
7265 -- MEDIUM A small number of messages are output.
7266 --
7267 -- HIGH A great number of messages are output, most of them not
7268 -- being useful for the user.

7284 -- /OBJECT_SEARCH=(directory,...)
7285 --
7286 -- When searching for library and object files, look in the specified
7287 -- directories. The order in which library files are searched is the same
7288 -- as for MAKE.
7292 -- /PROJECT=file
7293 --
7294 -- Specify a project file to use. By default, FIND and XREF will try to
7295 -- locate a project file in the current directory.
7296 --
7297 -- If a project file is either specified or found by the tools, then the
7298 -- content of the source directory and object directory lines are added
7299 -- as if they had been specified respectively by /SOURCE_SEARCH and
7300 -- /OBJECT_SEARCH.
7304 -- /PROJECT_FILE=filename
7305 --
7306 -- Specifies the main project file to be used. The project files rooted
7307 -- at the main project file will be parsed before doing any processing.
7308 -- The source and object directories to be searched will be communicated
7309 -- to gnatxref through logical names ADA_PRJ_INCLUDE_FILE and
7310 -- ADA_PRJ_OBJECTS_FILE.
7314 -- /SEARCH=(directory,...)
7315 --
7316 -- Equivalent to:
7317 -- /OBJECT_SEARCH=(directory,...) /SOURCE_SEARCH=(directory,...)
7321 -- /SOURCE_SEARCH=(directory,...)
7322 --
7323 -- When looking for source files also look in the specified directories.
7324 -- The order in which source file search is undertaken is the same as for
7325 -- MAKE.
7329 -- /SUBDIRS=dir
7330 --
7331 -- The actual directories (object, exec, library, ...) are subdirectories
