21 -- GNAT was originally developed by the GNAT team at New York University. --
22 -- Extensive contributions were provided by Ada Core Technologies Inc. --
23 -- --
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 999.
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

425 -- /PROJECT_FILE=filename
426 --
427 -- Specifies the main project file to be used. The project files rooted
428 -- at the main project file will be parsed before the invocation of the
429 -- binder. The source and object directories to be searched will be
430 -- communicated to the binder through logical names ADA_PRJ_INCLUDE_FILE
431 -- and ADA_PRJ_OBJECTS_FILE.
440 -- /READ_SOURCES[=(keyword[,...])]
441 -- /NOREAD_SOURCES
442 --
443 -- The following keyword are accepted:
444 --
445 -- ALL (D) Require source files to be present. In this mode, the
446 -- binder insists on being able to locate all source files
447 -- that are referenced and checks their consistency. In
448 -- normal mode, if a source file cannot be located it is
449 -- simply ignored. If you specify the ALL keyword, a
450 -- missing source file is an error.
451 --
452 -- NONE Exclude source files. In this mode, the binder only
453 -- checks that ALI files are consistent with one another.
454 -- source files are not accessed. The binder runs faster
455 -- in this mode, and there is still a guarantee that the
456 -- resulting program is self-consistent.
457 --
458 -- If a source file has been edited since it was last
459 -- compiled and you specify the NONE keyword, the binder
460 -- will not detect that the object file is out of date
461 -- with the source file.
462 --
463 -- This is the same as specifying /NOREAD_SOURCES.
464 --
465 -- AVAILABLE Check that object files are consistent with one
466 -- another and are consistent with any source files that
467 -- can be located.
471 -- NODOC (see /READ_SOURCES)
475 -- /RENAME_MAIN=xxx
476 --
477 -- Renames the generated main program from main to xxx.
478 -- This is useful in the case of some cross-building environments, where
479 -- the actual main program is separate from the one generated
480 -- by GNAT BIND.
489 -- /REPORT_ERRORS[=(keyword[,...])]
490 -- VERBOSE (D)
491 -- BRIEF
492 -- DEFAULT
493 -- /NOREPORT_ERRORS
494 --
495 -- With the DEFAULT keyword (which is not the default when the binder is
496 -- run from GNAT BIND) or the /NOREPORT_ERRORS qualifier, brief error
497 -- messages are generated to SYS$ERROR. If the VERBOSE keyword is
498 -- present, a header is written to SYS$OUTPUT and any error messages are
499 -- directed to SYS$OUTPUT All that is written to SYS$ERROR is a brief
500 -- summary message.
501 --
502 -- If the BRIEF keyword is specified, the binder will generate brief error
503 -- messages to SYS$ERROR even if verbose mode is specified. This is
504 -- relevant only when used together with the VERBOSE keyword or /VERBOSE
505 -- qualifier.
509 -- NODOC (see /REPORT_ERRORS)
513 -- /NORESTRICTION_LIST (D)
514 -- /RESTRICTION_LIST
515 --
516 -- Generate list of pragma Restrictions that could be applied to the
517 -- current unit. This is useful for code audit purposes, and also may be
518 -- used to improve code generation in some cases.
525 -- /RETURN_CODES=POSIX (D)
526 -- /RETURN_CODES=VMS
527 --
528 -- Specifies the style of default exit code returned. Must be used in
529 -- conjunction with and match the Link qualifier with same name.
530 --
531 -- POSIX (D) Return Posix success (0) by default.
532 --
533 -- VMS Return VMS success (1) by default.
537 -- /RUNTIME_SYSTEM=xxx
538 --
539 -- Binds against an alternate runtime system named xxx or RTS-xxx.
543 -- /SEARCH=(directory[,...])
544 --
545 -- When looking for source or object files also look in directories
546 -- specified.
547 --
548 -- This is the same as specifying both /LIBRARY_SEARCH and /SOURCE_SEARCH
549 -- for a directory.
553 -- /SHARED
554 -- /NOSHARED
555 --
556 -- Link against a shared GNAT run time when available.
560 -- /TIME_SLICE=nnn
561 --
562 -- Set the time slice value to nnn milliseconds. A value of zero means no
563 -- time slicing and also indicates to the tasking run time to match as
564 -- close as possible to the annex D requirements of the RM.
568 -- /SOURCE_SEARCH=(directory[,...])
569 --
570 -- When looking for source files also look in directories specified.
574 -- /STATIC

577 -- Link against a static GNAT run time.
581 -- /STORE_TRACEBACKS (D)
582 -- /NOSTORE_TRACEBACKS
583 --
584 -- Store tracebacks in exception occurrences.
585 -- This is the default on VMS, with the zero-cost exception mechanism.
586 -- This qualifier has no impact, except when using the setjmp/longjmp
587 -- exception mechanism, with the GNAT COMPILE qualifier /LONGJMP_SETJMP.
591 -- /SUBDIRS=dir
592 --
593 -- The actual directories (object, exec, library, ...) are subdirectories
594 -- of the directory specified in the project file. If the subdirectory
595 -- does not exist, it is created automatically.
599 -- /TIME_STAMP_CHECK (D)
600 --
601 -- Time stamp errors will be treated as errors.
602 --
603 -- /NOTIME_STAMP_CHECK
604 --
605 -- Ignore time stamp errors. Any time stamp error messages are treated as
606 -- warning messages. This switch essentially disconnects the normal
607 -- consistency checking, and the resulting program may have undefined
608 -- semantics if inconsistent units are present.
609 --
610 -- This means that /NOTIME_STAMP_CHECK should be used only in unusual
611 -- situations, with extreme care.
615 -- /VERBOSE (D)
616 -- /NOVERBOSE
617 --
618 -- Equivalent to /REPORT_ERRORS=VERBOSE.
627 -- /WARNINGS[=(keyword[,...])]
628 -- /NOWARNINGS
629 --
630 -- The following keywords are supported:
631 --
632 -- NORMAL (D) Print warning messages and treat them as warning.
633 -- SUPPRESS Suppress all warning messages (same as /NOWARNINGS).
634 -- ERROR Treat any warning messages as fatal errors
638 -- NODOC (see /WARNINGS)
653 -- /NOWIDE_CHARACTER_ENCODING (D)
654 -- /WIDE_CHARACTER_ENCODING[=encode-type]
655 --
656 -- Specifies the mechanism used to encode wide characters, overriding
657 -- the default as set by the /WIDE_CHARACTER_ENCODING option for the
658 -- compilation of the main program.
662 -- /NOZERO_MAIN (D)
663 -- /ZERO_MAIN
664 --
665 -- Normally the binder checks that the unit name given on the command line
666 -- corresponds to a suitable main subprogram. When /ZERO_MAIN is used,
667 -- a list of ALI files can be given, and the execution of the program
668 -- consists of elaboration of these units in an appropriate order.

942 -- Generate "Source_Reference" pragmas. Use this qualifier if the output
943 -- files are regarded as temporary and development is to be done in terms
944 -- of the original unchopped file. The /REFERENCE qualifier causes
945 -- "Source_Reference" pragmas to be inserted into each of the generated
946 -- files to refers back to the original file name and line number. The
947 -- result is that all error messages refer back to the original unchopped

1164 -- Switches for GNAT COMPILE --
1165 -------------------------------
1169 -- /NO83 (D)
1170 -- /83
1171 --
1172 -- Although GNAT is primarily an Ada 95 compiler, it accepts this
1173 -- qualifier to specify that an Ada 83 mode program is being compiled. If
1174 -- you specify this qualifier, GNAT rejects Ada 95 extensions and applies
1175 -- Ada 83 semantics. It is not possible to guarantee this qualifier does
1176 -- a perfect job; for example, some subtle tests of pathological cases,
1177 -- such as are found in ACVC tests that have been removed from the ACVC
1178 -- suite for Ada 95, may not compile correctly. However for practical
1179 -- purposes, using this qualifier should ensure that programs that
1180 -- compile correctly under the /83 qualifier can be ported reasonably
1181 -- easily to an Ada 83 compiler. This is the main use of this qualifier.
1182 --
1183 -- With few exceptions (most notably the need to use "<>" on
1184 -- unconstrained generic formal parameters), it is not necessary to use
1185 -- this qualifier switch when compiling Ada 83 programs, because, with
1186 -- rare and obscure exceptions, Ada 95 is upwardly compatible with Ada
1187 -- 83. This means that a correct Ada 83 program is usually also a correct
1188 -- Ada 95 program.
1192 -- /95 (D)
1193 --
1194 -- Allows GNAT to recognize the full range of Ada 95 constructs.
1195 -- This is the normal default for GNAT Pro.
1199 -- /05 (D)
1200 --
1201 -- Allows GNAT to recognize all implemented proposed Ada 2005
1202 -- extensions. See features file for list of implemented features.
1206 -- /ADD_PROJECT_SEARCH_PATH=(directory[,...])
1207 --
1208 -- Add directories to the project search path.
1212 -- /NOASM (D)
1213 -- /ASM
1214 --
1215 -- Use to cause the assembler source file to be generated, using S as the
1216 -- filetype, instead of the object file. This may be useful if you need
1217 -- to examine the generated assembly code.
1234 -- /NOCHECKS
1235 -- /CHECKS[=(keyword[,...])]
1236 --
1237 -- If you compile with the default options, GNAT will insert many runtime
1238 -- checks into the compiled code, including code that performs range
1239 -- checking against constraints, but not arithmetic overflow checking for
1240 -- integer operations (including division by zero) or checks for access
1241 -- before elaboration on subprogram calls. All other runtime checks, as
1242 -- required by the Ada 95 Reference Manual, are generated by default.
1243 --
1244 -- You may specify one or more of the following keywords to the /CHECKS
1245 -- qualifier to modify this behavior:
1246 --
1247 -- DEFAULT The behavior described above. This is the default
1248 -- if the /CHECKS qualifier is not present on the
1249 -- command line. Same as /NOCHECKS.
1250 --
1251 -- OVERFLOW Enables overflow checking for integer operations and
1252 -- checks for access before elaboration on subprogram
1253 -- calls. This causes GNAT to generate slower and larger
1254 -- executable programs by adding code to check for both
1255 -- overflow and division by zero (resulting in raising
1256 -- "Constraint_Error" as required by Ada semantics).
1257 -- Similarly, GNAT does not generate elaboration check
1258 -- by default, and you must specify this keyword to
1259 -- enable them.
1260 --
1261 -- Note that this keyword does not affect the code
1262 -- generated for any floating-point operations; it
1263 -- applies only to integer operations. For floating-point,
1264 -- GNAT has the "Machine_Overflows" attribute set to
1265 -- "False" and the normal mode of operation is to generate
1266 -- IEEE NaN and infinite values on overflow or invalid
1267 -- operations (such as dividing 0.0 by 0.0).
1268 --
1269 -- ELABORATION Enables dynamic checks for access-before-elaboration
1270 -- on subprogram calls and generic instantiations.
1271 --
1272 -- ASSERTIONS The pragmas "Assert" and "Debug" normally have no
1273 -- effect and are ignored. This keyword causes "Assert"
1274 -- and "Debug" pragmas to be activated, as well as
1275 -- "Check", "Precondition" and "Postcondition" pragmas.
1276 --
1277 -- SUPPRESS_ALL Suppress all runtime checks as though you have "pragma
1278 -- Suppress (all_checks)" in your source. Use this switch
1279 -- to improve the performance of the code at the expense
1280 -- of safety in the presence of invalid data or program
1281 -- bugs.
1282 --
1283 -- DEFAULT Suppress the effect of any option OVERFLOW or
1284 -- ASSERTIONS.
1285 --
1286 -- FULL (D) Similar to OVERFLOW, but suppress the effect of any
1287 -- option ELABORATION or SUPPRESS_ALL.
1288 --
1289 -- These keywords only control the default setting of the checks. You
1290 -- may modify them using either "Suppress" (to remove checks) or
1291 -- "Unsuppress" (to add back suppressed checks) pragmas in your program
1292 -- source.
1296 -- NODOC (see /CHECKS)
1300 -- /NOCOMPRESS_NAMES (D)
1301 -- /COMPRESS_NAMES
1302 --
1303 -- Compress debug information and external symbol name table entries.
1304 -- In the generated debugging information, and also in the case of long
1305 -- external names, the compiler uses a compression mechanism if the name
1306 -- is very long. This compression method uses a checksum, and avoids
1307 -- trouble on some operating systems which have difficulty with very long
1308 -- names.
1312 -- /CONFIGURATION_PRAGMAS_FILE=file
1313 --
1314 -- Specify a configuration pragmas file that need to be taken into account
1318 -- /CURRENT_DIRECTORY (D)
1319 -- /NOCURRENT_DIRECTORY
1320 --
1321 -- Look for source files in the default directory.
1325 -- /DATA_PREPROCESSING=file_name
1326 --
1327 -- This qualifier indicates to the compiler the file name (without
1328 -- directory information) of the preprocessor data file to use.
1329 -- The preprocessor data file should be found in the source directories.
1330 --
1331 -- A preprocessing data file is a text file with significant lines
1332 -- indicating how should be preprocessed either a specific source or all
1333 -- sources not mentioned in other lines. A significant line is a non
1334 -- empty, non comment line. Comments are similar to Ada comments.
1335 --
1336 -- Each significant line starts with either a literal string or the
1337 -- character '*'. A literal string is the file name (without directory
1338 -- information) of the source to preprocess. A character '*' indicates the
1339 -- preprocessing for all the sources that are not specified explicitly on
1340 -- other lines. It is an error to have two lines with the same file name
1341 -- or two lines starting with the character '*'.
1342 --
1343 -- After the file name or the character '*', another optional literal
1344 -- string indicating the file name of the definition file to be used for
1345 -- preprocessing. (see 15.3 Form of Definitions File. The definition files
1346 -- are found by the compiler in one of the source directories. In some
1347 -- cases, when compiling a source in a directory other than the current
1348 -- directory, if the definition file is in the current directory, it may
1349 -- be necessary to add the current directory as a source directory through
1350 -- qualifier "/SEARCH=[]", otherwise the compiler would not find the
1351 -- definition file.
1352 --
1353 -- Then, optionally, switches similar to those of gnatprep may be found.
1354 -- Those switches are:
1355 --
1356 -- -b Causes both preprocessor lines and the lines deleted by
1357 -- preprocessing to be replaced by blank lines, preserving
1358 -- the line number. This switch is always implied;
1359 -- however, if specified after `-c' it cancels the effect
1360 -- of `-c'.
1361 --
1362 -- -c Causes both preprocessor lines and the lines deleted by
1363 -- preprocessing to be retained as comments marked with
1364 -- the special string "--! ".
1365 --
1366 -- -Dsymbol=value Define or redefine a symbol, associated with value.
1367 -- A symbol is an Ada identifier, or an Ada reserved word,
1368 -- with the exception of "if", "else", "elsif", "end",
1369 -- "and", "or" and "then". value is either a literal
1370 -- string, an Ada identifier or any Ada reserved word.
1371 -- A symbol declared with this switch replaces a symbol
1372 -- with the same name defined in a definition file.
1373 --
1374 -- -s Causes a sorted list of symbol names and values to be
1375 -- listed on the standard output file.
1376 --
1377 -- -u Causes undefined symbols to be treated as having the
1378 -- value FALSE in the context of a preprocessor test.
1379 -- In the absence of this option, an undefined symbol
1380 -- in a #if or #elsif test will be treated as an error.
1381 --
1382 -- Examples of valid lines in a preprocessor data file:
1383 --
1384 -- "toto.adb" "prep.def" -u
1385 -- -- preprocess "toto.adb", using definition file "prep.def",
1386 -- -- undefined symbol are False.
1387 --
1388 -- * -c -DVERSION=V101
1389 -- -- preprocess all other sources without a definition file;
1390 -- -- suppressed lined are commented; symbol VERSION has the value
1391 -- -- V101.
1392 --
1393 -- "titi.adb" "prep2.def" -s
1394 -- -- preprocess "titi.adb", using definition file "prep2.def";
1395 -- -- list all symbols with their values.
1410 -- /DEBUG[=debug-level]
1411 -- /NODEBUG
1412 --
1413 -- Specifies how much debugging information is to be included in
1414 -- the resulting object fie.
1415 --
1416 -- 'debug-level' is one of the following:
1417 --
1418 -- SYMBOLS (D) Include both debugger symbol records and traceback
1419 -- in the object file.
1420 --
1421 -- ALL Include debugger symbol records, traceback plus
1422 -- extra debug information in the object file.
1423 --
1424 -- NONE Excludes both debugger symbol records and traceback
1425 -- from the object file. Same as /NODEBUG.
1426 --
1427 -- TRACEBACK Includes only traceback records in the object
1428 -- file. This is the default when /DEBUG is not used.
1432 -- NODOC (see /Debug)
1439 -- /NODISTRIBUTION_STUBS (D)
1440 -- /DISTRIBUTION_STUBS[=dist-opt]
1441 --
1442 -- 'dist-opt' is either RECEIVER (the default) or SENDER and indicates
1443 -- that stubs for use in distributed programs (see the Distributed
1444 -- Systems Annex of the Ada RM) should be generated.
1448 -- NODOC (see /DISTRIBUTION_STUBS)
1452 -- /NOERROR_LIMIT (D)
1453 -- /ERROR_LIMIT=nnn
1454 --
1455 -- NNN is a decimal integer in the range of 1 to 999999 and limits the
1456 -- number of error messages to be generated to that number. Once that
1457 -- number has been reached, the compilation is abandoned.
1458 -- Specifying 999999 is equivalent to /NOERROR_LIMIT.
1462 -- NODOC (see /ERROR_LIMIT)
1466 -- /NOEXPAND_SOURCE (D)
1467 -- /EXPAND_SOURCE
1468 --
1469 -- Produces a listing of the expanded code in Ada source form. For
1470 -- example, all tasking constructs are reduced to appropriate run-time
1471 -- library calls.
1475 -- /NOEXTENSIONS_ALLOWED (D)
1476 -- /EXTENSIONS_ALLOWED
1477 --
1478 -- GNAT specific language extensions allowed.
1482 -- /EXTERNAL_REFERENCE="name=val"
1483 --
1484 -- Specifies an external reference to the project manager. Useful only if

1486 --
1487 -- Example:
1488 -- /EXTERNAL_REFERENCE="DEBUG=TRUE"
1492 -- /FILE_NAME_MAX_LENGTH=nnn
1493 --
1494 -- Activates file name "krunching". NNN, a decimal integer in the range
1495 -- 1-999, indicates the maximum allowable length of a file name (not

1497 -- name krunching.
1501 -- /NOFOLLOW_LINKS_FOR_FILES (D)
1502 -- /FOLLOW_LINKS_FOR_FILES
1503 --
1504 -- Follow links when parsing project files
1508 -- /NOFORCE_ALI (D)
1509 -- /FORCE_ALI
1510 --
1511 -- In normal operation mode, the .ALI file is not generated if any
1512 -- illegalities are detected in the program. The use of this qualifier
1513 -- forces generation of the .ALI file. This file is marked as being
1514 -- in error, so it cannot be used for binding purposes, but it does
1515 -- contain reasonably complete cross-reference information, and thus may
1516 -- be useful for use by tools (e.g. semantic browsing tools or integrated
1517 -- development environments) that are driven from the .ALI file.
1521 -- /NOFULL_PATH_IN_BRIEF_MESSAGES (D)
1522 -- /FULL_PATH_IN_BRIEF_MESSAGES
1523 --
1524 -- When using project files, if some errors or warnings are detected

1574 --
1575 -- Normally GNAT recognizes the Latin-1 character set in source program

1580 --
1581 -- DEFAULT (D) Equivalent to 1, below. Also equivalent to

1583 --
1584 -- 1 The basic character set is Latin-1. This character
1585 -- set is defined by ISO standard 8859, part 1. The lower
1586 -- half (character codes 16#00# ... 16#7F#) is identical
1587 -- to standard ASCII coding, but the upper half is used
1588 -- to represent additional characters. This includes
1589 -- extended letters used by European languages, such as
1590 -- the umlaut used in German.
1591 --
1592 -- You may use any of these extended characters freely
1593 -- in character or string literals. In addition, the
1594 -- extended characters that represent letters can be
1595 -- used in identifiers.
1596 --
1597 -- 2 Latin-2 letters allowed in identifiers, with uppercase
1598 -- and lowercase equivalence.
1599 --
1600 -- 3 Latin-3 letters allowed in identifiers, with uppercase
1601 -- and lower case equivalence.
1602 --
1603 -- 4 Latin-4 letters allowed in identifiers, with uppercase
1604 -- and lower case equivalence.
1605 --
1606 -- PC IBM PC code page 437. This code page is the normal
1607 -- default for PCs in the U.S. It corresponds to the
1608 -- original IBM PC character set. This set has some, but
1609 -- not all, of the extended Latin-1 letters, but these
1610 -- letters do not have the same encoding as Latin-1. In
1611 -- this mode, these letters are allowed in identifiers
1612 -- with uppercase and lowercase equivalence.
1613 --
1614 -- PC850 This code page (850) is a modification of 437 extended
1615 -- to include all the Latin-1 letters, but still not with
1616 -- the usual Latin-1 encoding. In this mode, all these
1617 -- letters are allowed in identifiers with uppercase and
1618 -- lower case equivalence.
1619 --
1620 -- FULL_UPPER Any character in the range 80-FF allowed in
1621 -- identifiers, and all are considered distinct. In

1623 -- equivalences in this range.
1624 --
1625 -- NO_UPPER No upper-half characters in the range 80-FF are

1636 -- NODOC (see /IDENTIFIER_CHARACTER_SET)
1640 -- /IGNORE_REP_CLAUSES
1641 --
1642 -- Causes all representation clauses to be ignored and treated as
1643 -- comments. Useful when compiling foreign code (for example when ASIS
1644 -- is used to analyze such code).
1648 -- /NOIMMEDIATE_ERRORS (D)
1649 -- /IMMEDIATE_ERRORS
1650 --
1651 -- Causes errors to be displayed as soon as they are encountered, rather
1652 -- than after compilation is terminated. If GNAT terminates prematurely
1653 -- or goes into an infinite loop, the last error message displayed may
1654 -- help to pinpoint the culprit.
1663 -- /NOINLINE (D)
1664 -- /INLINE[=keyword]
1665 --
1666 -- Selects the level of inlining for your program. In the absence of this
1667 -- qualifier, GNAT does not attempt inlining across units and does not
1668 -- need to access the bodies of subprograms for which "pragma Inline" is
1669 -- specified if they are not in the current unit.
1670 --
1671 -- The supported keywords are as follows:
1672 --
1673 -- PRAGMA (D) Recognize and process "Inline" pragmas. However,
1674 -- for the inlining to actually occur, optimization
1675 -- must be enabled. This enables inlining across unit
1676 -- boundaries, that is, inlining a call in one unit of
1677 -- a subprogram declared in a with'ed unit. The compiler
1678 -- will access these bodies, creating an extra source
1679 -- dependency for the resulting object file, and where
1680 -- possible, the call will be inlined.
1681 --
1682 -- This qualifier also turns on full optimization and
1683 -- requests GNAT to try to attempt automatic inlining
1684 -- of small subprograms within a unit.
1685 --
1686 -- Specifying /OPTIMIZE=NONE will disable the main effect
1687 -- of this qualifier, but you may specify other
1688 -- optimization options, to get either lower
1689 -- (/OPTIMIZE=SOME) or higher (/OPTIMIZE=UNROLL_LOOPS)
1690 -- levels of optimization.
1691 --
1692 -- FULL Front end inlining. The front end inlining activated
1693 -- by this switch is generally more extensive, and quite
1694 -- often more effective than the standard PRAGMA inlining
1695 -- mode. It will also generate additional dependencies.
1696 --
1697 -- SUPPRESS Suppresses all inlining, even if other optimization
1698 -- or inlining switches are set.
1702 -- NODOC (see /INLINE)
1707 -- /NO_INTERSPERSE_SOURCE (D)
1708 -- /INTERSPERSE_SOURCE
1709 --
1710 -- Causes output from /XDEBUG or /EXPAND_SOURCE to be interspersed with
1711 -- lines from the original source file, output as comment lines with the
1712 -- associated line number.
1717 -- /NO_JUSTIFY_MESSAGES (D)
1718 -- /JUSTIFY_MESSAGES=nnn
1719 --
1720 -- Causes error messages to be reformatted so that a message and all its
1721 -- continuation lines count as one warning or error in the statistics on
1722 -- total errors, and the message is broken down into lines (justified) so
1723 -- that no line is longer than nnn characters. The default message
1724 -- behavior (each message counted separately and not reformatted to fit
1725 -- a particular line length) can be obtained using /NO_JUSTIFY_MESSAGES.
1730 -- NODOC (see /JUSTIFY_MESSAGES)
1734 -- /MAX_LINE_LENGTH=nnn
1735 --
1736 -- Set maximum line length.
1737 -- The length of lines must not exceed the given value nnn.
1741 -- /NOLIST (D)
1742 -- /LIST
1743 --
1744 -- Cause a full listing of the file to be generated. In the case where
1745 -- a body is compiled, the corresponding spec is also listed, along
1746 -- with any subunits.
1750 -- /MAPPING_FILE=file_name
1751 --
1752 -- Use mapping file file_name
1753 --
1754 -- A mapping file is a way to communicate to the compiler two mappings:
1755 -- from unit names to file names (without any directory information) and
1756 -- from file names to path names (with full directory information).
1757 -- These mappings are used by the compiler to short-circuit the path
1758 -- search.
1759 --
1760 -- The use of mapping files is not required for correct operation of the
1761 -- compiler, but mapping files can improve efficiency, particularly when
1762 -- sources are read over a slow network connection. In normal operation,
1763 -- you need not be concerned with the format or use of mapping files,
1764 -- and /MAPPING_FILE is not a qualifier that you would use explicitly.
1765 -- It is intended only for use by automatic tools such as GNAT MAKE
1766 -- running under the project file facility. The description here of the
1767 -- format of mapping files is provided for completeness and for possible
1768 -- use by other tools.
1769 --
1770 -- A mapping file is a sequence of sets of three lines. In each set, the
1771 -- first line is the unit name, in lower case, with "%s" appended for
1772 -- specifications and "%b" appended for bodies; the second line is the
1773 -- file name; and the third line is the path name.
1774 --
1775 -- Example:
1776 --
1777 -- main%b
1778 -- main.2_ada
1779 -- /gnat/project1/sources/main.2_ada
1780 --
1781 -- When qualifier ?MAPPING_FILE is specified, the compiler will create in
1782 -- memory the two mappings from the specified file. If there is any
1783 -- problem (non existent file, truncated file or duplicate entries),
1784 -- no mapping will be created.
1785 --
1786 -- Several /MAPPING_FILE qualifiers may be specified; however, only the
1787 -- last one on the command line will be taken into account.
1788 --
1789 -- When using a project file, GNAT MAKE creates a temporary mapping file
1790 -- and communicates it to the compiler using this switch.
1799 -- /MESSAGES_PROJECT_FILE[=messages-option]
1800 --
1801 -- Specifies the "verbosity" of the parsing of project files.
1802 -- messages-option may be one of the following:
1803 --
1804 -- DEFAULT (D) No messages are output if there is no error or warning.
1805 --
1806 -- MEDIUM A small number of messages are output.
1807 --
1808 -- HIGH A great number of messages are output, most of them not
1809 -- being useful for the user.
1813 -- /MAX_NESTING=nnn
1814 --
1815 -- Set maximum level of nesting of constructs (including subprograms,
1816 -- loops, blocks, packages, and conditionals).
1817 -- The level of nesting must not exceed the given value nnn.
1818 -- A value of zero disable this style check (not enabled by default).
1822 -- /NO_GNAT_ADC
1823 --
1824 -- Cause the compiler to ignore any configuration pragmas file GNAT.ADC
1825 -- in the default directory. Implied by qualifier /PROJECT_FILE.
1826 -- Often used in conjunction with qualifier /CONFIGURATION_PRAGMAS_FILE.
1830 -- /NOLOAD
1831 --
1832 -- Cause the compiler to operate in semantic check mode with full
1833 -- checking for all illegalities specified in the reference manual, but
1834 -- without generation of any source code (no object or ALI file
1835 -- generated).
1836 --
1837 -- Since dependent files must be accessed, you must follow the GNAT
1838 -- semantic restrictions on file structuring to operate in this mode:
1839 --
1840 -- o The needed source files must be accessible.
1841 -- o Each file must contain only one compilation unit.
1842 -- o The file name and unit name must match.
1843 --
1844 -- The output consists of error messages as appropriate. No object file
1845 -- or ALI file is generated. The checking corresponds exactly to the
1846 -- notion of legality in the Ada reference manual.
1847 --
1848 -- Any unit can be compiled in semantics-checking-only mode, including
1849 -- units that would not normally be compiled (generic library units,
1850 -- subunits, and specifications where a separate body is present).
1854 -- /NOSTD_INCLUDES
1855 --
1856 -- Do not look in the default directory for source files of the runtime.
1860 -- /NOSTD_LIBRARIES
1861 --
1862 -- Do not look for library files in the system default directory.
1881 -- /NOOPTIMIZE (D)
1882 -- /OPTIMIZE[=(keyword[,...])]
1883 --
1884 -- Selects the level of optimization for your program. The supported
1885 -- keywords are as follows:
1886 --
1887 -- ALL (D) Perform most optimizations, including those that
1888 -- may be expensive.
1889 --
1890 -- NONE Do not do any optimizations. Same as /NOOPTIMIZE.
1891 --
1892 -- SOME Perform some optimizations, but omit ones that
1893 -- are costly in compilation time.
1894 --
1895 -- SPACE Optimize space usage
1896 --
1897 -- DEVELOPMENT Same as SOME.
1898 --
1899 -- INLINING Full optimization, and also attempt automatic inlining
1900 -- of small subprograms within a unit
1901 --
1902 -- UNROLL_LOOPS Try to unroll loops. This keyword may be specified
1903 -- with any keyword above other than NONE. Loop
1904 -- unrolling usually, but not always, improves the
1905 -- performance of programs.
1906 --
1907 -- NO_STRICT_ALIASING
1908 -- Suppress aliasing analysis. When optimization is
1909 -- enabled (ALL or SOME above), the compiler assumes
1910 -- that pointers do in fact point to legitimate values
1911 -- of the pointer type (allocated from the proper pool).
1912 -- If this assumption is violated, e.g. by the use of
1913 -- unchecked conversion, then it may be necessary to
1914 -- suppress this assumption using this keyword (which
1915 -- may be specified only in conjunction with any
1916 -- keyword above, other than NONE).
1920 -- NODOC (see /OPTIMIZE)
1924 -- /OUTPUT_FILE=fname
1925 --
1926 -- This has the same effect as /LIST except that the output is written
1927 -- to a file instead of to standard output. If the given fname
1928 -- does not start with a period, then it is the full name of the file
1929 -- to be written. If fname starts with a period, the name of the file
1930 -- is the concatenation of to the name of the file being compiled with
1931 -- fname where the period is replace by an underline. For example, if
1932 -- file xyz.adb is compiled with -gnatl=.lst, then the output is written
1933 -- to file xyz.adb_lst.
1937 -- /NOPOLLING (D)
1938 -- /POLLING
1939 --
1940 -- Enable polling. See the description of pragma Polling in the GNAT
1941 -- Reference Manual for full details.
1945 -- /PROJECT_FILE=filename
1946 --
1947 -- Specifies the main project file to be used. The project files rooted
1948 -- at the main project file will be parsed before the invocation of the
1949 -- compiler. The source and object directories to be searched will be
1950 -- communicated to the compiler through logical names
1951 -- ADA_PRJ_INCLUDE_FILE and ADA_PRJ_OBJECTS_FILE.
1955 -- /PRINT_STANDARD
1956 --
1957 -- cause the compiler to output a representation of package Standard
1958 -- in a form very close to standard Ada. It is not quite possible to
1959 -- do this and remain entirely Standard (since new numeric base types
1960 -- cannot be created in standard Ada), but the output is easily
1961 -- readable to any Ada programmer, and is useful to determine the
1962 -- characteristics of target dependent types in package Standard.
1967 -- /NO_TREAT_RESTRICTIONS_AS_WARNINGS (D)
1968 -- /TREAT_RESTRICTIONS_AS_WARNINGS
1969 --
1970 -- Causes all restrictions to be treated as warnings (pragma Restriction
1971 -- treated as Restriction_Warnings, pragma Profile as Profile_Warnings,
1972 -- and pragma Ravenscar sets restriction warnings instead of restrictions)
1985 -- /NOREPORT_ERRORS (D)
1986 -- /REPORT_ERRORS[=(keyword[,...])]
1987 --
1988 -- Change the way errors are reported. The following keywords are
1989 -- supported:
1990 --
1991 -- VERBOSE (D) Verbose mode. Full error output with source lines
1992 -- to SYS$OUTPUT.
1993 --
1994 -- BRIEF Generate the brief format error messages to
1995 -- SYS$OUTPUT as well as the verbose format message or
1996 -- full listing.
1997 --
1998 -- FULL Normally, the compiler suppresses error messages that
1999 -- are likely to be redundant. This keyword causes all
2000 -- error messages to be generated. One particular effect
2001 -- is for the case of references to undefined variables.
2002 -- If a given variable is referenced several times, the
2003 -- normal format of messages produces one error. With
2004 -- FULL, each undefined reference produces a separate
2005 -- error message.
2006 --
2007 -- IMMEDIATE Normally, the compiler saves up error messages and
2008 -- generates them at the end of compilation in proper
2009 -- sequence. This keyword causes error messages to be
2010 -- generated as soon as they are detected. The use of
2011 -- IMMEDIATE usually causes error messages to be
2012 -- generated out of sequence. Use it when the compiler
2013 -- blows up due to an internal error. In this case, the
2014 -- error messages may be lost. Sometimes blowups are
2015 -- the result of mishandled error messages, so you may
2016 -- want to run with this keyword to determine whether
2017 -- any error messages were generated.
2018 --
2019 -- DEFAULT Turn off VERBOSE and BRIEF. Same as /NOREPORT_ERRORS.
2023 -- NODOC (see /REPORT_ERRORS)
2042 -- /NOREPRESENTATION_INFO (D)
2043 -- /REPRESENTATION_INFO[=(keyword[,...])]
2044 --
2045 -- This qualifier controls output from the compiler of a listing showing
2046 -- representation information for declared types and objects.
2047 --
2048 -- ARRAYS (D) Size and alignment information is listed for
2049 -- declared array and record types.
2050 --
2051 -- ARRAYS_FILE Similar to ARRAYS, but the output is to a file
2052 -- with the name 'file_rep' where 'file' is the name
2053 -- of the corresponding source file.
2054 --
2055 -- NONE no information is output (equivalent to omitting
2056 -- the /REPRESENTATION_INFO qualifiers).
2057 --
2058 -- OBJECTS Size and alignment information is listed for all
2059 -- declared types and objects.
2060 --
2061 -- OBJECTS_FILE Similar to OBJECTS, but the output is to a file
2062 -- with the name 'file_rep' where 'file' is the name
2063 -- of the corresponding source file.
2064 --
2065 -- SYMBOLIC Symbolic expression information for values that
2066 -- are computed at run time for variant records.
2067 --
2068 -- SYMBOLIC_FILE Similar to SYMBOLIC, but the output is to a file
2069 -- with the name 'file_rep' where 'file' is the name
2070 -- of the corresponding source file.
2071 --
2072 -- DEFAULT Equivalent to ARRAYS.
2076 -- NODOC (see /REPRESENTATION_INFO)
2080 -- /RUNTIME_SYSTEM=xxx
2081 --
2082 -- Build against an alternate runtime system named xxx or RTS-xxx.
2086 -- /SEARCH=(directory[,...])
2087 --
2088 -- When looking for source files also look in directories specified.
2205 -- /NOSTYLE_CHECKS (D)
2206 -- /STYLE_CHECKS[=(keyword,[...])]
2207 --
2208 -- Normally, GNAT permits any code layout consistent with the reference
2209 -- manual requirements. This qualifier imposes style checking on the
2210 -- input source code. The following keywords are supported:
2211 --
2212 -- ALL_BUILTIN (D) Equivalent to the following list of options:
2213 -- 3, ATTRIBUTE, BLANKS, COMMENTS, END, VTABS,
2214 -- HTABS, IF_THEN, KEYWORD, LAYOUT, LINE_LENGTH,
2215 -- PRAGMA, REFERENCES, SPECS, TOKEN.
2216 --
2217 -- 1 .. 9 Specify indentation level from 1 to 9.
2218 -- The general style of required indentation is as
2219 -- specified by the examples in the Ada Reference
2220 -- Manual. Full line comments must be aligned with
2221 -- the -- starting on a column that is a multiple
2222 -- of the alignment level.
2223 --
2224 -- ATTRIBUTE Check attribute casing.
2225 -- Attribute names, including the case of keywords
2226 -- such as digits used as attributes names,
2227 -- must be written in mixed case, that is,
2228 -- the initial letter and any letter following an
2229 -- underscore must be uppercase.
2230 -- All other letters must be lowercase.
2231 --
2232 -- ARRAY_INDEXES Check indexes of array attributes.
2233 -- For array attributes First, Last, Range,
2234 -- or Length, the index number must be omitted
2235 -- for one-dimensional arrays and is required
2236 -- for multi-dimensional arrays.
2237 --
2238 -- BLANKS Blanks not allowed at statement end.
2239 -- Trailing blanks are not allowed at the end of
2240 -- statements. The purpose of this rule, together
2241 -- with option HTABS (no horizontal tabs), is to
2242 -- enforce a canonical format for the use of
2243 -- blanks to separate source tokens.
2244 --
2245 -- COMMENTS Check comments.
2246 -- Comments must meet the following set of rules:
2247 --
2248 -- * The "--" that starts the column must either
2249 -- start in column one, or else at least one
2250 -- blank must precede this sequence.
2251 --
2252 -- * Comments that follow other tokens on a line
2253 -- must have at least one blank following the
2254 -- "--" at the start of the comment.
2255 --
2256 -- * Full line comments must have two blanks
2257 -- following the "--" that starts the comment,
2258 -- with the following exceptions.
2259 --
2260 -- * A line consisting only of the "--"
2261 -- characters, possibly preceded by blanks is
2262 -- permitted.
2263 --
2264 -- * A comment starting with "--x" where x is
2265 -- a special character is permitted. This
2266 -- allows proper processing of the output
2267 -- generated by specialized tools including
2268 -- gnatprep (where --! is used) and the SPARK
2269 -- annotation language (where --# is used).
2270 -- For the purposes of this rule, a special
2271 -- character is defined as being in one of the
2272 -- ASCII ranges 16#21#..16#2F# or
2273 -- 16#3A#..16#3F#.
2274 --
2275 -- * A line consisting entirely of minus signs,
2276 -- possibly preceded by blanks, is permitted.
2277 -- This allows the construction of box
2278 -- comments where lines of minus signs are
2279 -- used to form the top and bottom of the box.
2280 --
2281 -- * If a comment starts and ends with "--" is
2282 -- permitted as long as at least one blank
2283 -- follows the initial "--". Together with
2284 -- the preceding rule, this allows the
2285 -- construction of box comments, as shown in
2286 -- the following example:
2287 --
2288 -- ---------------------------
2289 -- -- This is a box comment --
2290 -- ---------------------------
2291 --
2292 -- DOS_LINE_ENDINGS Check that no DOS line terminators are present
2293 -- All lines must be terminated by a single
2294 -- ASCII.LF character. In particular the DOS line
2295 -- terminator sequence CR / LF is not allowed).
2296 --
2297 -- END Check end/exit labels.
2298 -- Optional labels on end statements ending
2299 -- subprograms and on exit statements exiting
2300 -- named loops, are required to be present.
2301 --
2302 -- GNAT Enforces a set of style conventions that
2303 -- match the style used in the GNAT source code.
2304 -- This maybe useful when developing code that
2305 -- is eventually intended to be incorporated into
2306 -- GNAT. For further details, see GNAT sources.
2307 --
2308 -- HTABS No horizontal tabs.
2309 -- Horizontal tab characters are not permitted in
2310 -- the source text. Together with the BLANKS
2311 -- (no blanks at end of line) option, this
2312 -- enforces a canonical form for the use of blanks
2313 -- to separate source tokens.
2314 --
2315 -- IF_THEN Check if-then layout.
2316 -- The keyword then must appear either on the
2317 -- same line as the corresponding if, or on a line
2318 -- on its own, lined up under the if with at least
2319 -- one non-blank line in between containing all or
2320 -- part of the condition to be tested.
2321 --
2322 -- KEYWORD Check keyword casing.
2323 -- All keywords must be in lower case (with the
2324 -- exception of keywords such as digits used as
2325 -- attribute names to which this check does not
2326 -- apply).
2327 --
2328 -- LAYOUT Check layout.
2329 -- Layout of statement and declaration constructs
2330 -- must follow the recommendations in the Ada
2331 -- Reference Manual, as indicated by the form of
2332 -- the syntax rules. For example an else keyword
2333 -- must be lined up with the corresponding if
2334 -- keyword.
2335 --
2336 -- There are two respects in which the style rule
2337 -- enforced by this check option are more liberal
2338 -- than those in the Ada Reference Manual.
2339 -- First in the case of record declarations,
2340 -- it is permissible to put the record keyword on
2341 -- the same line as the type keyword, and then
2342 -- the end in end record must line up under type.
2343 -- For example, either of the following two
2344 -- layouts is acceptable:
2345 --
2346 -- type q is record
2347 -- a : integer;
2348 -- b : integer;
2349 -- end record;
2350 --
2351 -- type q is
2352 -- record
2353 -- a : integer;
2354 -- b : integer;
2355 -- end record;
2356 --
2357 -- Second, in the case of a block statement,
2358 -- a permitted alternative is to put the block
2359 -- label on the same line as the declare or begin
2360 -- keyword, and then line the end keyword up under
2361 -- the block label. For example both the following
2362 -- are permitted:
2363 --
2364 --
2365 --
2366 -- Block : declare
2367 -- A : Integer := 3;
2368 -- begin
2369 -- Proc (A, A);
2370 -- end Block;
2371 --
2372 -- Block :
2373 -- declare
2374 -- A : Integer := 3;
2375 -- begin
2376 -- Proc (A, A);
2377 -- end Block;
2378 --
2379 -- The same alternative format is allowed for
2380 -- loops. For example, both of the following are
2381 -- permitted:
2382 --
2383 --
2384 --
2385 -- Clear : while J < 10 loop
2386 -- A (J) := 0;
2387 -- end loop Clear;
2388 --
2389 -- Clear :
2390 -- while J < 10 loop
2391 -- A (J) := 0;
2392 -- end loop Clear;
2393 --
2394 --
2395 --
2396 -- LINE_LENGTH Check maximum line length.
2397 -- The length of source lines must not exceed 79
2398 -- characters, including any trailing blanks
2399 -- The value of 79 allows convenient display on
2400 -- an 80 character wide device or window, allowing
2401 -- for possible special treatment of 80 character
2402 -- lines.
2403 --
2404 -- NONE Clear any previously set style checks.
2405 --
2406 -- ORDERED_SUBPROGRAMS Check order of subprogram bodies.
2407 -- All subprogram bodies in a given scope (e.g.
2408 -- a package body) must be in alphabetical order.
2409 -- The ordering rule uses normal Ada rules for
2410 -- comparing strings, ignoring casing of letters,
2411 -- except that if there is a trailing numeric
2412 -- suffix, then the value of this suffix is used
2413 -- in the ordering (e.g. Junk2 comes before
2414 -- Junk10).
2415 --
2416 -- PRAGMA Check pragma casing.
2417 -- Pragma names must be written in mixed case,
2418 -- that is, the initial letter and any letter
2419 -- following an underscore must be uppercase.
2420 -- All other letters must be lowercase.
2421 --
2422 -- REFERENCES Check references.
2423 -- All identifier references must be cased in the
2424 -- same way as the corresponding declaration.
2425 -- No specific casing style is imposed on
2426 -- identifiers. The only requirement is for
2427 -- consistency of references with declarations.
2428 --
2429 -- SPECS Check separate specs.
2430 -- Separate declarations ("specs") are required
2431 -- for subprograms (a body is not allowed to serve
2432 -- as its own declaration). The only exception is
2433 -- that parameterless library level procedures are
2434 -- not required to have a separate declaration.
2435 -- This exception covers the most frequent form of
2436 -- main program procedures.
2437 --
2438 -- STANDARD_CASING Check casing of entities in Standard.
2439 -- Any identifier from Standard must be cased to
2440 -- match the presentation in the Ada Reference
2441 -- Manual (for example, Integer and ASCII.NUL).
2442 --
2443 -- TOKEN Check token spacing.
2444 -- The following token spacing rules are enforced:
2445 --
2446 -- * The keywords abs and not must be followed
2447 -- by a space.
2448 --
2449 -- * The token => must be surrounded by spaces.
2450 --
2451 -- * The token <> must be preceded by a space or
2452 -- a left parenthesis.
2453 --
2454 -- * Binary operators other than ** must be
2455 -- surrounded by spaces. There is no
2456 -- restriction on the layout of the ** binary
2457 -- operator.
2458 --
2459 -- * Colon must be surrounded by spaces.
2460 --
2461 -- * Colon-equal (assignment) must be surrounded
2462 -- by spaces.
2463 --
2464 -- * Comma must be the first non-blank character
2465 -- on the line, or be immediately preceded by
2466 -- a non-blank character, and must be followed
2467 -- by a space.
2468 --
2469 -- * If the token preceding a left paren ends
2470 -- with a letter or digit, then a space must
2471 -- separate the two tokens.
2472 --
2473 -- * A right parenthesis must either be the
2474 -- first non-blank character on a line, or it
2475 -- must be preceded by a non-blank character.
2476 --
2477 -- * A semicolon must not be preceded by
2478 -- a space, and must not be followed by
2479 -- a non-blank character.
2480 --
2481 -- * A unary plus or minus may not be followed
2482 -- by a space.
2483 --
2484 -- * A vertical bar must be surrounded by
2485 -- spaces.
2486 --
2487 -- In the above rules, appearing in column one is
2488 -- always permitted, that is, counts as meeting
2489 -- either a requirement for a required preceding
2490 -- space, or as meeting a requirement for no
2491 -- preceding space.
2492 --
2493 -- Appearing at the end of a line is also always
2494 -- permitted, that is, counts as meeting either
2495 -- a requirement for a following space,
2496 -- or as meeting a requirement for no following
2497 -- space.
2498 --
2499 -- UNNECESSARY_BLANK_LINES
2500 -- Check for unnecessary blank lines.
2501 -- A blank line is considered unnecessary if it
2502 -- appears at the end of the file, or if more
2503 -- than one blank line occurs in sequence.
2504 --
2505 -- VTABS No form feeds or vertical tabs.
2506 -- Form feeds or vertical tab characters are not
2507 -- permitted in the source text.
2508 --
2509 -- XTRA_PARENS Check for the use of an unnecessary extra
2510 -- level of parentheses (C - style) around
2511 -- conditions in if statements, while statements
2512 -- and exit statements.
2516 -- NODOC (see /STYLE_CHECKS)
2520 -- /SUBDIRS=dir
2521 --
2522 -- The actual directories (object, exec, library, ...) are subdirectories
2523 -- of the directory specified in the project file. If the subdirectory
2524 -- does not exist, it is created automatically.
2528 -- /SYMBOL_PREPROCESSING="symbol=value"
2529 --
2530 -- Define or redefine a preprocessing symbol, associated with value.
2531 -- If "=value" is not specified, then the value of the symbol is True.
2532 -- A symbol is an identifier, following normal Ada (case-insensitive)
2533 -- rules for its syntax, and value is any sequence (including an empty
2534 -- sequence) of characters from the set (letters, digits, period,
2535 -- underline). Ada reserved words may be used as symbols, with the
2536 -- exceptions of "if", "else", "elsif", "end", "and", "or" and "then".
2537 --
2538 -- A symbol declared with this qualifier on the command line replaces
2539 -- a symbol with the same name either in a definition file or specified
2540 -- with a switch -D in the preprocessor data file.
2541 --
2542 -- This qualifier is similar to qualifier /ASSOCIATE of
2543 -- GNAT PREPROCESSING.
2547 -- /NOSYNTAX_ONLY (D)
2548 -- /SYNTAX_ONLY
2549 --
2550 -- Run GNAT in syntax checking only mode. You can check a series of
2551 -- files in a single command, and can use wild cards to specify such a
2552 -- group of files.
2553 --
2554 -- You may use other qualifiers in conjunction with this qualifier. In
2555 -- particular, /LIST and /REPORT_ERRORS=VERBOSE are useful to control the
2556 -- format of any generated error messages.
2557 --
2558 -- The output is simply the error messages, if any. No object file or ALI
2559 -- file is generated by a syntax-only compilation. Also, no units other
2560 -- than the one specified are accessed. For example, if a unit "X" with's
2561 -- a unit "Y", compiling unit "X" in syntax check only mode does not
2562 -- access the source file containing unit "Y".
2563 --
2564 -- Normally, GNAT allows only a single unit in a source file. However,
2565 -- this restriction does not apply in syntax-check-only mode, and it is
2566 -- possible to check a file containing multiple compilation units
2567 -- concatenated together. This is primarily used by the GNAT CHOP
2568 -- command.
2572 -- /TABLE_MULTIPLIER=nnn
2573 --
2574 -- All compiler tables start at nnn times usual starting size.
2578 -- /TRACE_UNITS
2579 -- /NOTRACE_UNITS
2580 --
2581 -- This switch that does for the frontend what /VERBOSE does for the

2583 -- unit or nested unit, as it is being analyzed.
2587 -- /TREE_OUTPUT
2588 -- /NOTREE_OUTPUT
2589 --
2590 -- Cause GNAT to write the internal tree for a unit to a file (with the
2591 -- filetype ATB for a body or ATS for a spec). This is not normally
2592 -- required, but is used by separate analysis tools. Typically these
2593 -- tools do the necessary compilations automatically, so you should never
2594 -- have to specify this switch in normal operation.
2598 -- /TRY_SEMANTICS
2599 -- /NOTRY_SEMANTICS
2600 --
2601 -- In normal operation mode the compiler first parses the program and
2602 -- determines if there are any syntax errors. If there are, appropriate
2603 -- error messages are generated and compilation is immediately
2604 -- terminated. This qualifier tells GNAT to continue with semantic
2605 -- analysis even if syntax errors have been found. This may enable the
2606 -- detection of more errors in a single run. On the other hand, the
2607 -- semantic analyzer is more likely to encounter some internal fatal
2608 -- error when given a syntactically invalid tree.
2612 -- /NOUNITS_LIST (D)
2613 -- /UNITS_LIST
2614 --
2615 -- Print a list of units required by this compilation on SYS$OUTPUT. The

2683 -- /VALIDITY_CHECKING[=(keyword,[...])]
2684 --
2685 -- Control level of validity checking.
2686 --
2687 -- DEFAULT (D) In this mode checks are made to prevent
2688 -- erroneous behavior in accordance with the RM.
2689 -- Notably extra checks may be needed for case
2690 -- statements and subscripted array assignments.
2691 --
2692 -- NONE No special checks for invalid values are
2693 -- performed. This means that references to
2694 -- uninitialized variables can cause erroneous
2695 -- behavior from constructs like case statements
2696 -- and subscripted array assignments. In this
2697 -- mode, invalid values can lead to erroneous
2698 -- behavior.
2699 --
2700 -- FULL Every assignment is checked for validity, so
2701 -- that it is impossible to assign invalid values.
2702 -- The RM specifically allows such assignments,
2703 -- but in this mode, invalid values can never be
2704 -- assigned, and an attempt to perform such an
2705 -- assignment immediately raises Constraint_Error.
2706 -- This behavior is allowed (but not required) by
2707 -- the RM. This mode is intended as a debugging aid,
2708 -- and may be useful in helping to track down
2709 -- uninitialized variables. It may be useful to

2871 -- /NOWARNINGS
2872 --
2873 -- Suppress the output of all warning messages from the GNAT front end.
2874 -- Note that it does not suppress warnings from the gcc back end.
2875 --
2876 -- /WARNINGS[=(keyword[,...])]
2877 --
2878 -- In addition to error messages, corresponding to illegalities as
2879 -- defined in the reference manual, the compiler detects two kinds of
2880 -- warning situations. First, the compiler considers some constructs
2881 -- suspicious and generates a warning message to alert you to a possible
2882 -- error. Second, if the compiler detects a situation that is sure to
2883 -- raise an exception at runtime, it generates a warning message.
2884 --
2885 -- You may specify the following keywords to change this behavior:
2886 --
2887 -- DEFAULT (D) The default behavior above.
2888 --

2892 -- details on optional warning messages that
2893 -- can be individually controlled.
2894 -- The warnings that are not turned on by
2895 -- this option are BIASED_ROUNDING,

2899 --
2900 -- EVERY Activate every optional warning.
2901 -- Activates all optional warnings, including
2902 -- those listed above as exceptions for ALL.
2903 --
2904 -- NOALL Suppress all optional errors.
2905 -- Suppresses all optional warning messages

2907 --
2908 -- ALL_GCC Request additional messages from the GCC
2909 -- backend. Most of these are not relevant
2910 -- to Ada.
2911 --
2912 -- CONDITIONALS Activate warnings for conditional
2913 -- Expressions used in tests that are known
2914 -- to be True or False at compile time. The
2915 -- default is that such warnings are not
2916 -- generated.
2917 --
2918 -- NOCONDITIONALS Suppress warnings for conditional
2919 -- expressions used in tests that are known
2920 -- to be True or False at compile time.
2921 --
2922 -- IMPLICIT_DEREFERENCE Activate warnings on implicit dereferencing.
2923 -- The use of a prefix of an access type in an

2944 --
2945 -- ERRORS Warning messages are to be treated as errors.
2946 -- The warning string still appears, but the

2950 -- HIDING Activate warnings on hiding declarations.
2951 -- A declaration is considered hiding if it is
2952 -- for a non-overloadable entity, and it declares
2953 -- an entity with the same name as some other

2970 --
2971 -- NOIMPLEMENTATION Disables warnings for a with of an internal
2972 -- GNAT implementation unit.
2973 --
2974 -- INEFFECTIVE_INLINE Activate warnings on ineffective pragma Inlines
2975 -- Activates warnings for failure of front end
2976 -- inlining (activated by /INLINE=FULL) to inline
2977 -- a particular call. There are many reasons for
2978 -- not being able to inline a call, including most
2979 -- commonly that the call is too complex to
2980 -- inline. This warning can also be turned on
2981 -- using /INLINE=FULL.
2982 --
2983 -- NOINEFFECTIVE_INLINE Suppress warnings on ineffective pragma Inlines
2984 -- Suppresses warnings on ineffective pragma
2985 -- Inlines. If the inlining mechanism cannot

3011 -- MODIFIED_UNREF Activates warnings for variables that are
3012 -- assigned (using an initialization value or with
3013 -- one or more assignment statements) but whose
3014 -- value is never read. The warning is suppressed
3015 -- for volatile variables and also for variables
3016 -- that are renamings of other variables or for
3017 -- which an address clause is given. This warning
3018 -- can also be turned on using /WARNINGS/OPTIONAL.
3019 --
3020 -- NOMODIFIED_UNREF Disables warnings for variables that are
3021 -- assigned or initialized, but never read.
3022 --
3023 -- NORMAL Sets normal warning mode, in which enabled
3024 -- warnings are issued and treated as warnings
3025 -- rather than errors. This is the default mode.
3026 -- It can be used to cancel the effect of an
3027 -- explicit /WARNINGS=SUPPRESS or
3028 -- /WARNINGS=ERRORS. It also cancels the effect
3029 -- of the implicit /WARNINGS=ERRORS that is
3030 -- activated by the use of /STYLE=GNAT.
3031 --
3032 -- OBSOLESCENT Activates warnings for calls to subprograms
3033 -- marked with pragma Obsolescent and for use of
3034 -- features in Annex J of the Ada Reference
3035 -- Manual. In the case of Annex J, not all
3036 -- features are flagged. In particular use of the
3037 -- renamed packages (like Text_IO), use of package
3038 -- ASCII and use of the attribute 'Constrained are
3039 -- not flagged, since these are very common and
3040 -- would generate many annoying positive warnings.
3041 -- The default is that such warnings are not
3042 -- generated.

3044 -- NOOBSOLESCENT Disables warnings on use of obsolescent
3045 -- features.
3046 --
3047 -- OBJECT_RENAME Activate warnings for non limited objects
3048 -- renaming parameterless functions.
3049 --

3052 --
3053 -- OPTIONAL Equivalent to ALL.
3054 --
3055 -- NOOPTIONAL Equivalent to NOALL.
3056 --
3057 -- OVERLAYS Activate warnings for possibly unintended

3073 --
3074 -- NOREDUNDANT Suppress warnings for redundant constructs.
3075 --
3076 -- SUPPRESS Completely suppress the output of all warning
3077 -- messages. Same as /NOWARNINGS.
3078 --
3079 -- UNCHECKED_CONVERSIONS Activates warnings on unchecked conversions.
3080 -- Causes warnings to be generated for
3081 -- unchecked conversions when the two types are
3082 -- known at compile time to have different sizes.

3094 --
3095 -- UNREFERENCED_FORMALS Activate warnings on unreferenced formals.
3096 -- Causes a warning to be generated if a formal
3097 -- parameter is not referenced in the body of

3099 -- on using option ALL or UNUSED.
3100 --
3101 -- NOUNREFERENCED_FORMALS Suppress warnings on unreferenced formals.
3102 -- Suppresses warnings for unreferenced formal
3103 -- parameters. Note that the combination UNUSED

3105 -- effect of warning on unreferenced entities
3106 -- other than subprogram formals.
3107 --
3108 -- UNUSED Activates warnings to be generated for entities
3109 -- that are defined but not referenced, and for
3110 -- units that are with'ed and not referenced. In
3111 -- the case of packages, a warning is also
3112 -- generated if no entities in the package are
3113 -- referenced. This means that if the package
3114 -- is referenced but the only references are in
3115 -- use clauses or renames declarations, a warning
3116 -- is still generated. A warning is also generated
3117 -- for a generic package that is with'ed but never
3118 -- instantiated. In the case where a package or
3119 -- subprogram body is compiled, and there is a
3120 -- with on the corresponding spec that is only

3168 -- /NOWIDE_CHARACTER_ENCODING (D)
3169 -- /WIDE_CHARACTER_ENCODING[=encode-type]
3170 --
3171 -- Specifies the mechanism used to encode wide characters. 'encode-type'
3172 -- is one of the following:
3173 --
3174 -- BRACKETS (D) A wide character is encoded as ["xxxx"] where XXXX
3175 -- are four hexadecimal digits representing the coding
3176 -- ('Pos value) of the character in type
3177 -- Wide_Character. The hexadecimal digits may use upper
3178 -- or lower case letters.
3179 --
3180 -- This notation can also be used for upper half
3181 -- Character values using the format ["xx"] where XX is
3182 -- two hexadecimal digits representing the coding ('Pos
3183 -- value) of the character in type Character (or
3184 -- Wide_Character). The hexadecimal digits may use upper
3185 -- of lower case.
3186 --
3187 -- NONE No wide characters are allowed. Same
3188 -- as /NOWIDE_CHARACTER_ENCODING.
3189 --
3190 -- HEX In this encoding, a wide character is represented by
3191 -- the following five character sequence: ESC a b c d
3192 -- Where 'a', 'b', 'c', and 'd' are the four hexadecimal
3193 -- characters (using uppercase letters) of the wide
3194 -- character code. For example, ESC A345 is used to
3195 -- represent the wide character with code 16#A345#. This
3196 -- scheme is compatible with use of the full
3197 -- Wide_Character set.
3198 --
3199 -- UPPER The wide character with encoding 16#abcd# where the
3200 -- upper bit is on (in other words, "a" is in the range
3201 -- 8-F) is represented as two bytes, 16#ab# and 16#cd#.
3202 -- The second byte may never be a format control
3203 -- character, but is not required to be in the upper
3204 -- half. This method can be also used for shift-JIS or
3205 -- EUC, where the internal coding matches the external
3206 -- coding.
3207 --
3208 -- SHIFT_JIS A wide character is represented by a two-character
3209 -- sequence, 16#ab# and 16#cd#, with the restrictions
3210 -- described for upper-half encoding as described above.
3211 -- The internal character code is the corresponding JIS
3212 -- character according to the standard algorithm for
3213 -- Shift-JIS conversion. Only characters defined in the
3214 -- JIS code set table can be used with this encoding
3215 -- method.
3216 --
3217 -- UTF8 A wide character is represented using
3218 -- UCS Transformation Format 8 (UTF-8) as defined in Annex
3219 -- R of ISO 10646-1/Am.2. Depending on the character
3220 -- value, the representation is a one, two, or three byte
3221 -- sequence:
3222 --
3223 -- 16#0000#-16#007f#: 2#0xxxxxxx#
3224 -- 16#0080#-16#07ff#: 2#110xxxxx# 2#10xxxxxx#
3225 -- 16#0800#-16#ffff#: 2#1110xxxx# 2#10xxxxxx# 2#10xxxxxx#
3226 --
3227 -- where the xxx bits correspond to the left-padded bits
3228 -- of the 16-bit character value. Note that all lower
3229 -- half ASCII characters are represented as ASCII bytes
3230 -- and all upper half characters and other wide characters
3231 -- are represented as sequences of upper-half (The full
3232 -- UTF-8 scheme allows for encoding 31-bit characters as
3233 -- 6-byte sequences, but in this implementation, all UTF-8
3234 -- sequences of four or more bytes length will be treated
3235 -- as illegal).
3236 --
3237 -- EUC A wide character is represented by a two-character
3238 -- sequence 16#ab# and 16#cd#, with both characters being
3239 -- in the upper half. The internal character code is the
3240 -- corresponding JIS character according to the EUC
3241 -- encoding algorithm. Only characters defined in the JIS
3242 -- code set table can be used with this encoding method.

3256 -- The debugging information generated by the /DEBUG qualifier will then
3257 -- refer to the generated file. This allows source level debugging using
3258 -- the generated code which is sometimes useful for complex code, for
3259 -- example to find out exactly which part of a complex construction

4147 -- Switches for GNAT MAKE --
4148 ----------------------------
4157 -- /ACTIONS=(keyword[,...])
4158 --
4159 -- GNAT MAKE default behavior is to check if the sources are up to date,
4160 -- compile those sources that are not up to date, bind the main source,
4161 -- then link the executable.
4162 --
4163 -- With the /ACTIONS qualifier, GNAT MAKE may be restricted to one or
4164 -- two of these three steps:
4165 --
4166 -- o Compile
4167 -- o Bind
4168 -- o Link
4169 --
4170 --
4171 -- You may specify one or more of the following keywords to the /ACTIONS
4172 -- qualifier:
4173 --
4174 -- BIND Bind only. Can be combined with /ACTIONS=COMPILE
4175 -- to do compilation and binding, but no linking.
4176 -- Can be combined with /ACTIONS=LINK to do binding and
4177 -- linking. When not combined with /ACTIONS=COMPILE,
4178 -- all the units in the closure of the main program must
4179 -- have been previously compiled and must be up to date.
4180 --
4181 -- COMPILE Compile only. Do not perform binding, except when
4182 -- /ACTIONS=BIND is also specified. Do not perform
4183 -- linking, except if both /ACTIONS=BIND and /ACTIONS=LINK
4184 -- are also specified.
4185 --
4186 -- LINK Link only. Can be combined with /ACTIONS=BIND to do
4187 -- binding and linking. Linking will not be performed
4188 -- if combined with /ACTIONS=COMPILE but not with
4189 -- /ACTIONS=BIND\. When not combined with /ACTIONS=BIND
4190 -- all the units in the closure of the main program must
4191 -- have been previously compiled and must be up to date,
4192 -- and the main program need to have been bound.
4196 -- /ADD_PROJECT_SEARCH_PATH=(directory[,...])
4197 --
4198 -- Add directories to the project search path.
4202 -- /NOALL_FILES (D)
4203 -- /ALL_FILES
4204 --
4205 -- Consider all files in the make process, even the GNAT internal system
4206 -- files (for example, the predefined Ada library files). By default,
4207 -- GNAT MAKE does not check these files (however, if there is an
4208 -- installation problem, it will be caught when GNAT MAKE binds your
4209 -- program). You may have to specify this qualifier if you are working on
4210 -- GNAT itself. The vast majority of GNAT MAKE users never need to
4211 -- specify this switch. All GNAT internal files with will be compiled
4212 -- with /STYLE_CHECK=GNAT.
4216 -- /NOALL_PROJECTS (D)
4217 -- /ALL_PROJECTS
4218 --
4219 -- Implies /Unique.
4220 -- When used without project files, it is equivalent to /UNIQUE.
4221 -- When used with a project file with no main (neither on the command
4222 -- line nor in the attribute Main) check every source of every project,
4223 -- recompile all sources that are not up to date and rebuild libraries
4224 -- if necessary.
4228 -- /BINDER_QUALIFIERS
4229 --
4230 -- Any qualifiers specified after this qualifier other than
4231 -- /COMPILER_QUALIFIERS, /LINKER_QUALIFIERS and /MAKE_QUALIFIERS will be
4232 -- passed to any GNAT BIND commands generated by GNAT MAKE.
4236 -- /BND_LNK_FULL_PROJECT
4237 --
4238 -- Bind and link all sources of a project, without any consideration
4239 -- to attribute Main, if there is one. This qualifier need to be
4240 -- used in conjunction with the /PROJECT_FILE= qualifier and cannot
4241 -- be used with a main subprogram on the command line or for
4242 -- a library project file. As the binder is invoked with the option
4243 -- meaning "No Ada main subprogram", the user must ensure that the
4244 -- proper options are specified to the linker. This qualifier is
4245 -- normally used when the main subprogram is in a foreign language
4246 -- such as C.
4250 -- /COMPILER_QUALIFIERS
4251 --
4252 -- Any qualifiers specified after this qualifier other than
4253 -- /BINDER_QUALIFIERS, /LINKER_QUALIFIERS and /MAKE_QUALIFIERS will be
4254 -- passed to any GNAT COMPILE commands generated by GNAT MAKE.
4258 -- /CONDITIONAL_SOURCE_SEARCH=dir
4259 --
4260 -- Equivalent to "/SOURCE_SEARCH=dir /SKIP_MISSING=dir".
4264 -- /NOCONTINUE_ON_ERROR (D)
4265 -- /CONTINUE_ON_ERROR
4266 --
4267 -- Keep going. Continue as much as possible after a compilation error.
4268 -- To ease the programmer's task in case of compilation errors, the list
4269 -- of sources for which the compile fails is given when GNAT MAKE
4270 -- terminates.
4274 -- /CURRENT_DIRECTORY (D)
4275 -- /NOCURRENT_DIRECTORY
4276 --
4277 -- Look for source, library or object files in the default directory.
4281 -- /NODEPENDENCIES_LIST (D)
4282 -- /DEPENDENCIES_LIST
4283 --
4284 -- Check if all objects are up to date. If they are, output the object
4285 -- dependences to SYS$OUTPUT in a form that can be directly exploited in
4286 -- a Unix-style Makefile. By default, each source file is prefixed with
4287 -- its (relative or absolute) directory name. This name is whatever you
4288 -- specified in the various /SOURCE_SEARCH and /SEARCH qualifiers. If
4289 -- you also specify the /QUIET qualifier, only the source file names,
4290 -- without relative paths, are output. If you just specify the
4291 -- /DEPENDENCY_LIST qualifier, dependencies of the GNAT internal system
4292 -- files are omitted. This is typically what you want. If you also
4293 -- specify the /ALL_FILES qualifier, dependencies of the GNAT internal
4294 -- files are also listed. Note that dependencies of the objects in
4295 -- external Ada libraries (see the /SKIP_MISSING qualifier) are never
4296 -- reported.
4300 -- /DIRECTORY_OBJECTS=<file>
4301 --
4302 -- Put all object files and .ALI files in <file>.
4303 -- This qualifier is not compatible with /PROJECT_FILE.
4307 -- /NOPLAY_PROGRESS (D)
4308 -- /DISPLAY_PROGRESS
4309 --
4310 -- Display progress for each source, up to date or not, as a single line
4311 -- completed x out of y (zz%)
4312 -- If the file needs to be compiled this is displayed after the
4313 -- invocation of the compiler. These lines are displayed even in quiet
4314 -- output mode (/QUIET).
4318 -- /NODO_OBJECT_CHECK (D)
4319 -- /DO_OBJECT_CHECK
4320 --
4321 -- Don't compile, bind, or link. Output a single command that will
4322 -- recompile an out of date unit, if any. Repeated use of this option,
4323 -- followed by carrying out the indicated compilation, will eventually
4324 -- result in recompiling all required units.
4325 --
4326 -- If any ALI is missing during the process, GNAT MAKE halts and
4327 -- displays an error message.
4331 -- /EXECUTABLE=exec-name
4332 --
4333 -- The name of the final executable program will be 'exec_name'. If this
4334 -- qualifier is omitted the default name for the executable will be the
4335 -- name of the input file with an EXE filetype. You may prefix
4336 -- 'exec_name' with a relative or absolute directory path.
4340 -- /EXTERNAL_REFERENCE="name=val"
4341 --
4342 -- Specifies an external reference to the project manager. Useful only if
4343 -- /PROJECT_FILE is used.
4344 --
4345 -- Example:
4346 -- /EXTERNAL_REFERENCE="DEBUG=TRUE"
4350 -- /NOFOLLOW_LINKS_FOR_FILES (D)
4351 -- /FOLLOW_LINKS_FOR_FILES
4352 --
4353 -- Follow links when parsing project files
4357 -- /NOFORCE_COMPILE (D)
4358 -- /FORCE_COMPILE
4359 --
4360 -- Force recompilations. Recompile all sources, even though some object
4361 -- files may be up to date, but don't recompile predefined or GNAT
4362 -- internal files unless the /ALL_FILES qualifier is also specified.
4366 -- /NOFULL_PATH_IN_BRIEF_MESSAGES (D)
4367 -- /FULL_PATH_IN_BRIEF_MESSAGES
4368 --
4369 -- When using project files, if some errors or warnings are detected
4370 -- during parsing and verbose mode is not in effect (no use of qualifier
4371 -- /VERBOSE), then error lines start with the full path name of the
4372 -- project file, rather than its simple file name.
4376 -- /NOHIGH_VERBOSITY (D)
4377 -- /HIGH_VERBOSITY
4378 --
4379 -- Displays the reason for all recompilations GNAT MAKE decides are
4380 -- necessary, in high verbosity. Equivalent to /VERBOSE.
4384 -- /NOIN_PLACE (D)
4385 -- /IN_PLACE
4386 --
4387 -- In normal mode, GNAT MAKE compiles all object files and ALI files
4388 -- into the current directory. If the /IN_PLACE switch is used,
4389 -- then instead object files and ALI files that already exist are over-
4390 -- written in place. This means that once a large project is organized
4391 -- into separate directories in the desired manner, then GNAT MAKE will
4392 -- automatically maintain and update this organization. If no ALI files
4393 -- are found on the Ada object path, the new object and ALI files are
4394 -- created in the directory containing the source being compiled.
4398 -- /SOURCE_INDEX=nnn
4399 --
4400 -- Specifies the index of the units in the source file
4401 -- By default, source files are mono-unit and there is no index
4402 -- When /SOURCE_INDEX=nnn is specified, only one main may be specified
4403 -- on the command line.
4407 -- /LIBRARY_SEARCH=(directory[,...])
4408 --
4409 -- Add the specified directories to the list of directories in which the
4410 -- linker will search for libraries.
4414 -- /LINKER_QUALIFIERS
4415 --
4416 -- Any qualifiers specified after this qualifier other than
4417 -- /COMPILER_QUALIFIERS, /BINDER_QUALIFIERS and /MAKE_QUALIFIERS will be
4418 -- passed to any GNAT LINK commands generated by GNAT LINK.
4422 -- /NOLOW_VERBOSITY (D)
4423 -- /LOW_VERBOSITY
4424 --
4425 -- Displays the reason for all recompilations GNAT MAKE decides are
4426 -- necessary, in low verbosity, that is with less output than
4427 -- /MEDIUM_VERBOSITY, /HIGH_VERBOSITY or /VERBOSE.
4431 -- /MAKE_QUALIFIERS
4432 --
4433 -- Any qualifiers specified after this qualifier other than
4434 -- /COMPILER_QUALIFIERS, /BINDER_QUALIFIERS and /LINKER_QUALIFIERS
4435 -- are for the benefit of GNAT MAKE itself.
4439 -- /NOMAPPING (D)
4440 -- /MAPPING
4441 --
4442 -- Use a mapping file. A mapping file is a way to communicate to the
4443 -- compiler two mappings: from unit names to file names (without any
4444 -- directory information) and from file names to path names (with full
4445 -- directory information). These mappings are used by the compiler to
4446 -- short-circuit the path search. When GNAT MAKE is invoked with this
4447 -- qualifier, it will create a mapping file, initially populated by the
4448 -- project manager, if /PROJECT_File= is used, otherwise initially empty.
4449 -- Each invocation of the compiler will add the newly accessed sources to
4450 -- the mapping file. This will improve the source search during the next
4451 -- invocations of the compiler
4455 -- /NOMEDIUM_VERBOSITY (D)
4456 -- /MEDIUM_VERBOSITY
4457 --
4458 -- Displays the reason for all recompilations GNAT MAKE decides are
4459 -- necessary, in medium verbosity, that is with potentially less output
4460 -- than /HIGH_VERBOSITY or /VERBOSE.
4469 -- /MESSAGES_PROJECT_FILE[=messages-option]
4470 --
4471 -- Specifies the "verbosity" of the parsing of project files.
4472 -- messages-option may be one of the following:
4473 --
4474 -- DEFAULT (D) No messages are output if there is no error or warning.
4475 --
4476 -- MEDIUM A small number of messages are output.
4477 --
4478 -- HIGH A great number of messages are output, most of them not
4479 -- being useful for the user.
4483 -- /NOMINIMAL_RECOMPILATION (D)
4484 -- /MINIMAL_RECOMPILATION
4485 --
4486 -- Specifies that the minimum necessary amount of recompilation
4487 -- be performed. In this mode GNAT MAKE ignores time stamp differences
4488 -- when the only modifications to a source file consist in
4489 -- adding/removing comments, empty lines, spaces or tabs.
4493 -- /NOCREATE_MISSING_DIRS (D)
4494 -- /CREATE_MISSING_DIRS
4495 --
4496 -- When an object directory, a library directory or an exec directory
4497 -- in missing, attempt to create the directory.
4501 -- /NOLINK
4502 --
4503 -- Compile only. Do not perform binding and linking. If the root unit is
4504 -- not a main unit, this is the default. Otherwise GNAT MAKE will
4505 -- attempt binding and linking unless all objects are up to date and the
4506 -- executable is more recent than the objects.
4507 -- This is equivalent to /ACTIONS=COMPILE
4511 -- /NOMAIN
4512 --
4513 -- No main subprogram. Bind and link the program even if the unit name
4514 -- given on the command line is a package name. The resulting executable
4515 -- will execute the elaboration routines of the package and its closure,
4516 -- then the finalization routines.
4520 -- /NON_PROJECT_UNIT_COMPILATION
4521 --
4522 -- Normally, when using project files, a unit that is not part of any
4523 -- project file, cannot be compile. These units may be compile, when
4524 -- needed, if this qualifier is specified.
4528 -- /NOSTD_INCLUDES
4529 --
4530 -- Do not look for sources the in the system default directory.
4534 -- /NOSTD_LIBRARIES
4535 --
4536 -- Do not look for library files in the system default directory.
4540 -- /OBJECT_SEARCH=(directory[,...])
4541 --
4542 -- When looking for library and object files look also in the specified
4543 -- directories.
4547 -- /NOPROCESSES (D)
4548 -- /PROCESSES=NNN
4549 --
4550 -- Use NNN processes to carry out the (re)compilations. If you have a
4551 -- multiprocessor machine, compilations will occur in parallel. In the
4552 -- event of compilation errors, messages from various compilations might
4553 -- get interspersed (but GNAT MAKE will give you the full ordered list of
4554 -- failing compiles at the end). This can at times be annoying. To get a
4555 -- clean list of error messages don't use this qualifier.
4559 -- NODOC (see /PROCESS)
4563 -- /PROJECT_FILE=filename
4564 --
4565 -- Specifies the main project file to be used. The project files rooted
4566 -- at the main project file will be parsed before any other processing to
4567 -- set the building environment.
4571 -- /NOQUIET (D)
4572 -- /QUIET
4573 --
4574 -- When this qualifiers is specified, the commands carried out by GNAT
4575 -- MAKE are not displayed.
4579 -- /NOREASONS (D)
4580 -- /REASONS
4581 --
4582 -- Displays the reason for all recompilations GNAT MAKE decides are
4583 -- necessary.
4587 -- /RUNTIME_SYSTEM=xxx
4588 --
4589 -- Build against an alternate runtime system named xxx or RTS-xxx.
4593 -- /SEARCH=(directory[,...])
4594 --
4595 -- Search the specified directories for both source and object files.
4599 -- /SKIP_MISSING=(directory[,...])
4600 --
4601 -- Skip missing library sources if ALI in 'directory'.
4605 -- /SOURCE_SEARCH=(directory[,...])

4607 -- When looking for source files also look in the specified directories.
4611 -- /NOSTANDARD_OUTPUT_FOR_COMMANDS (D)
4612 -- /STANDARD_OUTPUT_FOR_COMMANDS
4613 --
4614 -- Output the commands for the compiler, the binder and the linker
4615 -- on SYS$OUTPUT, instead of SYS$ERROR.
4619 -- /SUBDIRS=dir
4620 --
4621 -- The actual directories (object, exec, library, ...) are subdirectories
4622 -- of the directory specified in the project file. If the subdirectory
4623 -- does not exist, it is created automatically.
4627 -- /NOSWITCH_CHECK (D)
4628 -- /SWITCH_CHECK
4629 --
4630 -- Recompile if compiler switches have changed since last compilation.
4631 -- All compiler switches but -I and -o are taken into account in the
4632 -- following way: orders between different "first letter" switches are
4633 -- ignored, but orders between same switches are taken into account.
4634 -- For example, -O -O2 is different than -O2 -O, but -g -O is equivalent
4635 -- to -O -g.
4639 -- /NOUNIQUE (D)
4640 -- /UNIQUE
4641 --
4642 -- Recompile at most the main file. It implies /ACTIONS=COMPILE.
4643 -- Combined with /FORCE_COMPILE, it is equivalent to calling the compiler
4644 -- directly.
4648 -- /USE_MAPPING_FILE=file_name
4649 --
4650 -- Use a specific mapping file. The file 'file_name', specified as a path

6755 --
6756 -- Specify a project file to use. By default, FIND and XREF will try to
6757 -- locate a project file in the current directory.
6758 --
6759 -- If a project file is either specified or found by the tools, then the
6760 -- content of the source directory and object directory lines are added

6786 -- The order in which source file search is undertaken is the same as for
6787 -- MAKE.
6791 -- /SUBDIRS=dir
6792 --
6793 -- The actual directories (object, exec, library, ...) are subdirectories
