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)

1260 -- Equivalent to /05 (/2005 is the preferred usage).
1264 -- /05 (D)

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 -- /NOALIASING_CHECK (D)
1286 -- /ALIASING_CHECK
1287 --
1288 -- Check that there are no aliased parameters in subprogram calls.
1292 -- /NOASM (D)
1293 -- /ASM
1294 --
1295 -- Use to cause the assembler source file to be generated, using S as the
1296 -- filetype, instead of the object file. This may be useful if you need
1297 -- to examine the generated assembly code.
1301 -- /NO_ASSUME_VALID (D)
1302 -- /ASSUME_VALID
1303 --
1304 -- Use to tell the compiler to assume that all objects have valid values
1305 -- except those occurring as prefixes to 'Valid attributes. In the default
1306 -- mode, the compiler assumes that values may be invalid unless it can
1307 -- be sure that they are valid, and code is generated to allow for this
1308 -- possibility. The use of /ASSUME_VALID will improve the code.
1312 -- /NO_CATEGORIZATION_WARNINGS (D)
1313 -- /CATEGORIZATION_WARNINGS
1314 --
1315 -- Use to tell the compiler to disable categorization dependency errors.
1316 -- Ada requires that units that WITH one another have compatible
1317 -- categories, for example a Pure unit cannot WITH a Preelaborate unit.
1318 -- If this switch is used, these errors become warnings (which can be
1319 -- ignored, or suppressed in the usual manner). This can be useful in
1320 -- some specialized circumstances such as the temporary use of special
1321 -- test software.
1340 -- /NOCHECKS
1341 -- /CHECKS[=(keyword[,...])]
1342 --
1343 -- If you compile with the default options, GNAT will insert many runtime
1344 -- checks into the compiled code, including code that performs range
1345 -- checking against constraints, but not arithmetic overflow checking for
1346 -- integer operations (including division by zero) or checks for access
1347 -- before elaboration on subprogram calls. All other runtime checks, as
1348 -- required by the Ada 95 Reference Manual, are generated by default.
1349 --
1350 -- You may specify one or more of the following keywords to the /CHECKS
1351 -- qualifier to modify this behavior:
1352 --
1353 -- DEFAULT The behavior described above. This is the default
1354 -- if the /CHECKS qualifier is not present on the
1355 -- command line. Same as /NOCHECKS.
1356 --
1357 -- OVERFLOW Enables overflow checking in CHECKED mode for integer
1358 -- operations and checks for access before elaboration
1359 -- on subprogram calls. This causes GNAT to generate
1360 -- slower and larger executable programs by adding code
1361 -- to check for both overflow and division by zero
1362 -- (resulting in raising "Constraint_Error" as required
1363 -- by Ada semantics).
1364 -- Similarly, GNAT does not generate elaboration check
1365 -- by default, and you must specify this keyword to
1366 -- enable them.
1367 --
1368 -- Note that this keyword does not affect the code
1369 -- generated for any floating-point operations; it
1370 -- applies only to integer operations. For the case of
1371 -- floating-point, GNAT has the "Machine_Overflows"
1372 -- attribute set to "False" and the normal mode of
1373 -- operation is to generate IEEE NaN and infinite values
1374 -- on overflow or invalid operations (such as dividing
1375 -- 0.0 by 0.0).
1376 --
1377 -- ELABORATION Enables dynamic checks for access-before-elaboration
1378 -- on subprogram calls and generic instantiations.
1379 --
1380 -- ASSERTIONS The pragmas "Assert" and "Debug" normally have no
1381 -- effect and are ignored. This keyword causes "Assert"
1382 -- and "Debug" pragmas to be activated, as well as
1383 -- "Check", "Precondition" and "Postcondition" pragmas.
1384 --
1385 -- SUPPRESS_ALL Suppress all runtime checks as though you have
1386 -- "pragma Suppress (all_checks)" in your source. Use
1387 -- this switch to improve the performance of the code at
1388 -- the expense of safety in the presence of invalid data
1389 -- or program bugs.
1390 --
1391 -- UNSUPPRESS_ALL Cancels effect of previous SUPPRESS_ALL.
1392 --
1393 -- DEFAULT Suppress the effect of any option OVERFLOW or
1394 -- ASSERTIONS.
1395 --
1396 -- FULL (D) Similar to OVERFLOW, but suppress the effect of any
1397 -- option ELABORATION or SUPPRESS_ALL.
1398 --
1399 -- These keywords only control the default setting of the checks. You
1400 -- may modify them using either "Suppress" (to remove checks) or
1401 -- "Unsuppress" (to add back suppressed checks) pragmas in your program
1402 -- source.
1406 -- NODOC (see /CHECKS)
1410 -- /NOFLOAT_OVERFLOW_CHECK (D)
1411 -- /FLOAT_OVERFLOW_CHECK
1412 --
1413 -- Set mode to check overflow for all floating-point operations including
1414 -- those using an unconstrained predefined type (i.e. no infinities).
1418 -- /NOCOMPRESS_NAMES (D)
1419 -- /COMPRESS_NAMES
1420 --
1421 -- Compress debug information and external symbol name table entries.
1422 -- In the generated debugging information, and also in the case of long
1423 -- external names, the compiler uses a compression mechanism if the name
1424 -- is very long. This compression method uses a checksum, and avoids
1425 -- trouble on some operating systems which have difficulty with very long
1426 -- names.
1430 -- /CONFIGURATION_PRAGMAS_FILE=file

1432 -- Specify a configuration pragmas file that needs to be taken into
1433 -- account.

1438 -- /NOCURRENT_DIRECTORY
1439 --
1440 -- Look for source files in the default directory.
1444 -- /DATA_PREPROCESSING=file_name
1445 --
1446 -- This qualifier indicates to the compiler the file name (without
1447 -- directory information) of the preprocessor data file to use.
1448 -- The preprocessor data file should be found in the source directories.
1449 --
1450 -- A preprocessing data file is a text file with significant lines
1451 -- indicating how should be preprocessed either a specific source or all
1452 -- sources not mentioned in other lines. A significant line is a non
1453 -- empty, non comment line. Comments are similar to Ada comments.
1454 --
1455 -- Each significant line starts with either a literal string or the
1456 -- character '*'. A literal string is the file name (without directory
1457 -- information) of the source to preprocess. A character '*' indicates the
1458 -- preprocessing for all the sources that are not specified explicitly on
1459 -- other lines. It is an error to have two lines with the same file name
1460 -- or two lines starting with the character '*'.
1461 --
1462 -- After the file name or the character '*', another optional literal
1463 -- string indicating the file name of the definition file to be used for
1464 -- preprocessing. (see 15.3 Form of Definitions File. The definition files
1465 -- are found by the compiler in one of the source directories. In some
1466 -- cases, when compiling a source in a directory other than the current
1467 -- directory, if the definition file is in the current directory, it may
1468 -- be necessary to add the current directory as a source directory through
1469 -- qualifier "/SEARCH=[]", otherwise the compiler would not find the
1470 -- definition file.
1471 --
1472 -- Then, optionally, switches similar to those of gnatprep may be found.
1473 -- Those switches are:
1474 --
1475 -- -b Causes both preprocessor lines and the lines deleted by
1476 -- preprocessing to be replaced by blank lines, preserving
1477 -- the line number. This switch is always implied;
1478 -- however, if specified after `-c' it cancels the effect
1479 -- of `-c'.
1480 --
1481 -- -c Causes both preprocessor lines and the lines deleted by
1482 -- preprocessing to be retained as comments marked with
1483 -- the special string "--! ".
1484 --
1485 -- -Dsymbol=value Define or redefine a symbol, associated with value.
1486 -- A symbol is an Ada identifier, or an Ada reserved word,
1487 -- with the exception of "if", "else", "elsif", "end",
1488 -- "and", "or" and "then". value is either a literal
1489 -- string, an Ada identifier or any Ada reserved word.

1851 -- /NOINLINE (D)
1852 -- /INLINE[=keyword]
1853 --
1854 -- Selects the level of inlining for your program. In the absence of this
1855 -- qualifier, GNAT does not attempt inlining across units and does not
1856 -- need to access the bodies of subprograms for which "pragma Inline" is

1858 --
1859 -- The supported keywords are as follows:
1860 --
1861 -- PRAGMA (D) Recognize and process "Inline" pragmas. However,
1862 -- for the inlining to actually occur, optimization
1863 -- must be enabled. This enables inlining across unit
1864 -- boundaries, that is, inlining a call in one unit of
1865 -- a subprogram declared in a with'ed unit. The compiler
1866 -- will access these bodies, creating an extra source
1867 -- dependency for the resulting object file, and where
1868 -- possible, the call will be inlined.
1869 --
1870 -- This qualifier also turns on full optimization and
1871 -- requests GNAT to try to attempt automatic inlining
1872 -- of small subprograms within a unit.
1873 --
1874 -- Specifying /OPTIMIZE=NONE will disable the main effect
1875 -- of this qualifier, but you may specify other

1955 -- /MAPPING_FILE=file_name
1956 --
1957 -- Use mapping file file_name
1958 --
1959 -- A mapping file is a way to communicate to the compiler two mappings:
1960 -- from unit names to file names (without any directory information) and
1961 -- from file names to path names (with full directory information).
1962 -- These mappings are used by the compiler to short-circuit the path
1963 -- search.
1964 --
1965 -- The use of mapping files is not required for correct operation of the
1966 -- compiler, but mapping files can improve efficiency, particularly when
1967 -- sources are read over a slow network connection. In normal operation,
1968 -- you need not be concerned with the format or use of mapping files,
1969 -- and /MAPPING_FILE is not a qualifier that you would use explicitly.
1970 -- It is intended only for use by automatic tools such as GNAT MAKE
1971 -- running under the project file facility. The description here of the
1972 -- format of mapping files is provided for completeness and for possible
1973 -- use by other tools.
1974 --
1975 -- A mapping file is a sequence of sets of three lines. In each set, the
1976 -- first line is the unit name, in lower case, with "%s" appended for
1977 -- specifications and "%b" appended for bodies; the second line is the
1978 -- file name; and the third line is the path name.
1979 --
1980 -- Example:
1981 --
1982 -- main%b
1983 -- main.2_ada
1984 -- /gnat/project1/sources/main.2_ada
1985 --
1986 -- When qualifier ?MAPPING_FILE is specified, the compiler will create in
1987 -- memory the two mappings from the specified file. If there is any
1988 -- problem (non existent file, truncated file or duplicate entries),
1989 -- no mapping will be created.
1990 --
1991 -- Several /MAPPING_FILE qualifiers may be specified; however, only the
1992 -- last one on the command line will be taken into account.
1993 --
1994 -- When using a project file, GNAT MAKE creates a temporary mapping file
1995 -- and communicates it to the compiler using this switch.
2000 -- /MAX_INSTANTIATIONS=nnn
2001 --
2002 -- Specify the maximum number of instantiations permitted. The default
2003 -- value is 8000, which is probably enough for all programs except those
2004 -- containing some kind of runaway unintended instantiation loop.
2013 -- /MESSAGES_PROJECT_FILE[=messages-option]
2014 --
2015 -- Specifies the "verbosity" of the parsing of project files.
2016 -- messages-option may be one of the following:
2017 --
2018 -- DEFAULT (D) No messages are output if there is no error or warning.
2019 --
2020 -- MEDIUM A small number of messages are output.
2021 --
2022 -- HIGH A great number of messages are output, most of them not
2023 -- being useful for the user.
2027 -- /MULTI_UNIT_INDEX=nnn
2028 --
2029 -- Specify the index of the unit to compile in a multi-unit source file.
2033 -- /MAX_NESTING=nnn
2034 --
2035 -- Set maximum level of nesting of constructs (including subprograms,
2036 -- loops, blocks, packages, and conditionals).
2037 -- The level of nesting must not exceed the given value nnn.
2038 -- A value of zero disable this style check (not enabled by default).
2042 -- /NO_GNAT_ADC
2043 --
2044 -- Cause the compiler to ignore any configuration pragmas file GNAT.ADC
2045 -- in the default directory. Implied by qualifier /PROJECT_FILE.

2050 -- /NOLOAD
2051 --
2052 -- Cause the compiler to operate in semantic check mode with full
2053 -- checking for all illegalities specified in the reference manual, but
2054 -- without generation of any source code (no object or ALI file
2055 -- generated).
2056 --
2057 -- Since dependent files must be accessed, you must follow the GNAT
2058 -- semantic restrictions on file structuring to operate in this mode:
2059 --
2060 -- o The needed source files must be accessible.
2061 -- o Each file must contain only one compilation unit.
2062 -- o The file name and unit name must match.
2063 --
2064 -- The output consists of error messages as appropriate. No object file
2065 -- or ALI file is generated. The checking corresponds exactly to the
2066 -- notion of legality in the Ada reference manual.
2067 --
2068 -- Any unit can be compiled in semantics-checking-only mode, including
2069 -- units that would not normally be compiled (generic library units,
2070 -- subunits, and specifications where a separate body is present).
2074 -- /NOSTD_INCLUDES

2076 -- Do not look in the default directory for source files of the runtime.
2080 -- /NOSTD_LIBRARIES

2086 -- /NOWARNING_PRAGMAS
2087 --
2088 -- Causes all Warnings pragmas to be ignored. Useful to check if the
2089 -- program has obsolete warnings pragmas that are hiding problems.
2108 -- /NOOPTIMIZE (D)
2109 -- /OPTIMIZE[=(keyword[,...])]
2110 --
2111 -- Selects the level of optimization for your program. The supported
2112 -- keywords are as follows:
2113 --
2114 -- ALL (D) Perform most optimizations, including those that
2115 -- may be expensive.
2116 --
2117 -- NONE Do not do any optimizations. Same as /NOOPTIMIZE.

2125 --
2126 -- INLINING Full optimization, and also attempt automatic inlining
2127 -- of small subprograms within a unit
2128 --
2129 -- UNROLL_LOOPS Try to unroll loops. This keyword may be specified
2130 -- with any keyword above other than NONE. Loop

2132 -- performance of programs.
2133 --
2134 -- NO_STRICT_ALIASING
2135 -- Suppress aliasing analysis. When optimization is
2136 -- enabled (ALL or SOME above), the compiler assumes
2137 -- that pointers do in fact point to legitimate values
2138 -- of the pointer type (allocated from the proper pool).
2139 -- If this assumption is violated, e.g. by the use of
2140 -- unchecked conversion, then it may be necessary to
2141 -- suppress this assumption using this keyword (which
2142 -- may be specified only in conjunction with any
2143 -- keyword above, other than NONE).
2147 -- NODOC (see /OPTIMIZE)
2151 -- /OUTPUT_FILE=fname
2152 --
2153 -- This has the same effect as /LIST except that the output is written
2154 -- to a file instead of to standard output. If the given fname
2155 -- does not start with a period, then it is the full name of the file
2156 -- to be written. If fname starts with a period, the name of the file
2157 -- is the concatenation of to the name of the file being compiled with
2158 -- fname where the period is replace by an underline. For example, if
2159 -- file xyz.adb is compiled with -gnatl=.lst, then the output is written
2160 -- to file xyz.adb_lst.
2164 -- /OVERFLOW_CHECKS=nn
2165 --
2166 -- Set default overflow cheecking mode. If nn is a single digit, in the
2167 -- range 0-3, it sets the overflow checking mode for all expressions,

2169 --
2170 -- 1 all intermediate computations done using base type (STRICT)
2171 -- 2 minimize intermediate overflows (MINIMIZED)
2172 -- 3 eliminate intermediate overflows (ELIMINATED)
2173 --
2174 -- Otherwise nn can be two digits, both 1-3, and in this case the first
2175 -- digit sets the mode (using the above code) for expressions outside an
2176 -- assertion, and the second digit sets the mode for expressions within

2236 -- /PRINT_STANDARD
2237 --
2238 -- cause the compiler to output a representation of package Standard

2266 -- /NOREPORT_ERRORS (D)
2267 -- /REPORT_ERRORS[=(keyword[,...])]
2268 --
2269 -- Change the way errors are reported. The following keywords are
2270 -- supported:
2271 --
2272 -- VERBOSE (D) Verbose mode. Full error output with source lines
2273 -- to SYS$OUTPUT.
2274 --
2275 -- BRIEF Generate the brief format error messages to
2276 -- SYS$OUTPUT as well as the verbose format message or
2277 -- full listing.
2278 --
2279 -- FULL Normally, the compiler suppresses error messages that
2280 -- are likely to be redundant. This keyword causes all
2281 -- error messages to be generated. One particular effect
2282 -- is for the case of references to undefined variables.
2283 -- If a given variable is referenced several times, the
2284 -- normal format of messages produces one error. With
2285 -- FULL, each undefined reference produces a separate
2286 -- error message.
2287 --
2288 -- IMMEDIATE Normally, the compiler saves up error messages and
2289 -- generates them at the end of compilation in proper
2290 -- sequence. This keyword causes error messages to be
2291 -- generated as soon as they are detected. The use of
2292 -- IMMEDIATE usually causes error messages to be
2293 -- generated out of sequence. Use it when the compiler
2294 -- blows up due to an internal error. In this case, the
2295 -- error messages may be lost. Sometimes blowups are
2296 -- the result of mishandled error messages, so you may
2297 -- want to run with this keyword to determine whether
2298 -- any error messages were generated.
2299 --
2300 -- DEFAULT Turn off VERBOSE and BRIEF. Same as /NOREPORT_ERRORS.
2304 -- NODOC (see /REPORT_ERRORS)

2335 --
2336 -- ARRAYS_FILE Similar to ARRAYS, but the output is to a file

2379 -- /SCO_OUTPUT
2380 --
2381 -- Controls the output of SCO (Source Coverage Obligation) information
2382 -- in the generated ALI file. This information is used by advanced source

2526 -- /NOSTYLE_CHECKS (D)
2527 -- /STYLE_CHECKS[=(keyword,[...])]
2528 --
2529 -- Normally, GNAT permits any code layout consistent with the reference
2530 -- manual requirements. This qualifier imposes style checking on the
2531 -- input source code. The following keywords are supported:
2532 --
2533 -- ALL_BUILTIN (D) Equivalent to the following list of options:
2534 -- 3, ATTRIBUTE, BLANKS, COMMENTS2, END, VTABS,
2535 -- HTABS, IF_THEN, KEYWORD, LAYOUT, LINE_LENGTH,
2536 -- PRAGMA, REFERENCES, SPECS, TOKEN.
2537 --
2538 -- 1 .. 9 Specify indentation level from 1 to 9.
2539 -- The general style of required indentation is as
2540 -- specified by the examples in the Ada Reference
2541 -- Manual. Full line comments must be aligned with
2542 -- the -- starting on a column that is a multiple
2543 -- of the alignment level.
2544 --
2545 -- ATTRIBUTE Check attribute casing.
2546 -- Attribute names, including the case of keywords
2547 -- such as digits used as attributes names,
2548 -- must be written in mixed case, that is,
2549 -- the initial letter and any letter following an
2550 -- underscore must be uppercase.
2551 -- All other letters must be lowercase.
2552 --
2553 -- ARRAY_INDEXES Check indexes of array attributes.
2554 -- For array attributes First, Last, Range,
2555 -- or Length, the index number must be omitted
2556 -- for one-dimensional arrays and is required
2557 -- for multi-dimensional arrays.
2558 --
2559 -- BLANKS Blanks not allowed at statement end.
2560 -- Trailing blanks are not allowed at the end of
2561 -- statements. The purpose of this rule, together
2562 -- with option HTABS (no horizontal tabs), is to
2563 -- enforce a canonical format for the use of
2564 -- blanks to separate source tokens.
2565 --
2566 -- COMMENTS2 Check comments.
2567 -- COMMENTS Comments must meet the following set of rules:
2568 --
2569 -- * The "--" that starts the column must either
2570 -- start in column one, or else at least one
2571 -- blank must precede this sequence.
2572 --
2573 -- * Comments that follow other tokens on a line
2574 -- must have at least one blank following the
2575 -- "--" at the start of the comment.
2576 --
2577 -- * Full line comments must have two blanks
2578 -- following the "--" that starts the comment,
2579 -- with the following exceptions.
2580 --
2581 -- * A line consisting only of the "--"
2582 -- characters, possibly preceded by blanks is
2583 -- permitted.
2584 --
2585 -- * A comment starting with "--x" where x is
2586 -- a special character is permitted. This
2587 -- allows proper processing of the output
2588 -- generated by specialized tools including
2589 -- gnatprep (where --! is used) and the SPARK
2590 -- annotation language (where --# is used).
2591 -- For the purposes of this rule, a special
2592 -- character is defined as being in one of the
2593 -- ASCII ranges 16#21#..16#2F# or
2594 -- 16#3A#..16#3F#.
2595 --
2596 -- * A line consisting entirely of minus signs,
2597 -- possibly preceded by blanks, is permitted.
2598 -- This allows the construction of box
2599 -- comments where lines of minus signs are
2600 -- used to form the top and bottom of the box.
2601 --
2602 -- * If a comment starts and ends with "--" is
2603 -- permitted as long as at least one blank
2604 -- follows the initial "--". Together with
2605 -- the preceding rule, this allows the
2606 -- construction of box comments, as shown in
2607 -- the following example:
2608 --
2609 -- ---------------------------
2610 -- -- This is a box comment --
2611 -- ---------------------------
2612 --
2613 -- COMMENTS1 Check comments (single space).
2614 -- Like COMMENTS2, but the -- of a comment only
2615 -- requires one or more spaces following, instead
2616 -- of two or more spaces.
2617 --
2618 -- DOS_LINE_ENDINGS Check that no DOS line terminators are present
2619 -- All lines must be terminated by a single
2620 -- ASCII.LF character. In particular the DOS line
2621 -- terminator sequence CR / LF is not allowed).
2622 --
2623 -- END Check end/exit labels.
2624 -- Optional labels on end statements ending
2625 -- subprograms and on exit statements exiting
2626 -- named loops, are required to be present.
2627 --
2628 -- GNAT Enforces a set of style conventions that
2629 -- match the style used in the GNAT source code.
2630 -- This maybe useful when developing code that
2631 -- is eventually intended to be incorporated into
2632 -- GNAT. For further details, see GNAT sources.
2633 --
2634 -- HTABS No horizontal tabs.
2635 -- Horizontal tab characters are not permitted in
2636 -- the source text. Together with the BLANKS
2637 -- (no blanks at end of line) option, this
2638 -- enforces a canonical form for the use of blanks
2639 -- to separate source tokens.
2640 --
2641 -- IF_THEN Check if-then layout.
2642 -- The keyword then must appear either on the
2643 -- same line as the corresponding if, or on a line
2644 -- on its own, lined up under the if with at least
2645 -- one non-blank line in between containing all or
2646 -- part of the condition to be tested.
2647 --
2648 -- KEYWORD Check keyword casing.
2649 -- All keywords must be in lower case (with the
2650 -- exception of keywords such as digits used as
2651 -- attribute names to which this check does not
2652 -- apply).
2653 --
2654 -- LAYOUT Check layout.
2655 -- Layout of statement and declaration constructs
2656 -- must follow the recommendations in the Ada
2657 -- Reference Manual, as indicated by the form of
2658 -- the syntax rules. For example an else keyword
2659 -- must be lined up with the corresponding if
2660 -- keyword.
2661 --
2662 -- There are two respects in which the style rule
2663 -- enforced by this check option are more liberal
2664 -- than those in the Ada Reference Manual.
2665 -- First in the case of record declarations,
2666 -- it is permissible to put the record keyword on
2667 -- the same line as the type keyword, and then
2668 -- the end in end record must line up under type.
2669 -- For example, either of the following two
2670 -- layouts is acceptable:
2671 --
2672 -- type q is record
2673 -- a : integer;
2674 -- b : integer;
2675 -- end record;
2676 --
2677 -- type q is
2678 -- record
2679 -- a : integer;
2680 -- b : integer;
2681 -- end record;
2682 --
2683 -- Second, in the case of a block statement,
2684 -- a permitted alternative is to put the block
2685 -- label on the same line as the declare or begin
2686 -- keyword, and then line the end keyword up under
2687 -- the block label. For example both the following
2688 -- are permitted:
2689 --
2690 --
2691 --
2692 -- Block : declare
2693 -- A : Integer := 3;
2694 -- begin
2695 -- Proc (A, A);
2696 -- end Block;
2697 --
2698 -- Block :
2699 -- declare
2700 -- A : Integer := 3;
2701 -- begin
2702 -- Proc (A, A);
2703 -- end Block;
2704 --
2705 -- The same alternative format is allowed for
2706 -- loops. For example, both of the following are
2707 -- permitted:
2708 --
2709 --
2710 --
2711 -- Clear : while J < 10 loop
2712 -- A (J) := 0;
2713 -- end loop Clear;
2714 --
2715 -- Clear :
2716 -- while J < 10 loop
2717 -- A (J) := 0;
2718 -- end loop Clear;
2719 --
2720 --
2721 --
2722 -- LINE_LENGTH Check maximum line length.
2723 -- The length of source lines must not exceed 79
2724 -- characters, including any trailing blanks
2725 -- The value of 79 allows convenient display on
2726 -- an 80 character wide device or window, allowing
2727 -- for possible special treatment of 80 character
2728 -- lines.
2729 --
2730 -- NONE Clear any previously set style checks.
2731 --
2732 -- ORDERED_SUBPROGRAMS Check order of subprogram bodies.
2733 -- All subprogram bodies in a given scope (e.g.
2734 -- a package body) must be in alphabetical order.
2735 -- The ordering rule uses normal Ada rules for
2736 -- comparing strings, ignoring casing of letters,
2737 -- except that if there is a trailing numeric
2738 -- suffix, then the value of this suffix is used
2739 -- in the ordering (e.g. Junk2 comes before
2740 -- Junk10).
2741 --
2742 -- OVERRIDING_INDICATORS Check that overriding subprograms are
2743 -- explicitly marked as such. The declaration of
2744 -- a primitive operation of a type extension that
2745 -- overrides an inherited operation must carry
2746 -- an overriding indicator.
2747 --
2748 -- PRAGMA Check pragma casing.
2749 -- Pragma names must be written in mixed case,
2750 -- that is, the initial letter and any letter
2751 -- following an underscore must be uppercase.
2752 -- All other letters must be lowercase.
2753 --
2754 -- REFERENCES Check references.
2755 -- All identifier references must be cased in the
2756 -- same way as the corresponding declaration.
2757 -- No specific casing style is imposed on
2758 -- identifiers. The only requirement is for
2759 -- consistency of references with declarations.
2760 --
2761 -- SPECS Check separate specs.
2762 -- Separate declarations ("specs") are required
2763 -- for subprograms (a body is not allowed to serve
2764 -- as its own declaration). The only exception is
2765 -- that parameterless library level procedures are
2766 -- not required to have a separate declaration.
2767 -- This exception covers the most frequent form of
2768 -- main program procedures.
2769 --
2770 -- STANDARD_CASING Check casing of entities in Standard.
2771 -- Any identifier from Standard must be cased to
2772 -- match the presentation in the Ada Reference
2773 -- Manual (for example, Integer and ASCII.NUL).
2774 --
2775 -- TOKEN Check token spacing.
2776 -- The following token spacing rules are enforced:
2777 --
2778 -- * The keywords abs and not must be followed
2779 -- by a space.
2780 --
2781 -- * The token => must be surrounded by spaces.
2782 --
2783 -- * The token <> must be preceded by a space or
2784 -- a left parenthesis.
2785 --
2786 -- * Binary operators other than ** must be
2787 -- surrounded by spaces. There is no
2788 -- restriction on the layout of the ** binary
2789 -- operator.
2790 --
2791 -- * Colon must be surrounded by spaces.
2792 --
2793 -- * Colon-equal (assignment) must be surrounded
2794 -- by spaces.
2795 --
2796 -- * Comma must be the first non-blank character
2797 -- on the line, or be immediately preceded by
2798 -- a non-blank character, and must be followed
2799 -- by a space.
2800 --
2801 -- * If the token preceding a left paren ends
2802 -- with a letter or digit, then a space must
2803 -- separate the two tokens.
2804 --
2805 -- * A right parenthesis must either be the
2806 -- first non-blank character on a line, or it
2807 -- must be preceded by a non-blank character.
2808 --
2809 -- * A semicolon must not be preceded by
2810 -- a space, and must not be followed by
2811 -- a non-blank character.
2812 --
2813 -- * A unary plus or minus may not be followed
2814 -- by a space.
2815 --
2816 -- * A vertical bar must be surrounded by
2817 -- spaces.
2818 --
2819 -- In the above rules, appearing in column one is
2820 -- always permitted, that is, counts as meeting
2821 -- either a requirement for a required preceding
2822 -- space, or as meeting a requirement for no
2823 -- preceding space.
2824 --
2825 -- Appearing at the end of a line is also always
2826 -- permitted, that is, counts as meeting either
2827 -- a requirement for a following space,
2828 -- or as meeting a requirement for no following
2829 -- space.
2830 --
2831 -- UNNECESSARY_BLANK_LINES
2832 -- Check for unnecessary blank lines.
2833 -- A blank line is considered unnecessary if it
2834 -- appears at the end of the file, or if more
2835 -- than one blank line occurs in sequence.
2836 --
2837 -- VTABS No form feeds or vertical tabs.
2838 -- Form feeds or vertical tab characters are not
2839 -- permitted in the source text.
2840 --
2841 -- XTRA_PARENS Check for the use of an unnecessary extra
2842 -- level of parentheses (C - style) around
2843 -- conditions in if statements, while statements
2844 -- and exit statements.
2848 -- NODOC (see /STYLE_CHECKS)
2852 -- /SUBDIRS=dir
2853 --
2854 -- The actual directories (object, exec, library, ...) are subdirectories
2855 -- of the directory specified in the project file. If the subdirectory
2856 -- does not exist, it is created automatically.
2860 -- /SYMBOL_PREPROCESSING="symbol=value"
2861 --
2862 -- Define or redefine a preprocessing symbol, associated with value.
2863 -- If "=value" is not specified, then the value of the symbol is True.
2864 -- A symbol is an identifier, following normal Ada (case-insensitive)
2865 -- rules for its syntax, and value is any sequence (including an empty
2866 -- sequence) of characters from the set (letters, digits, period,
2867 -- underline). Ada reserved words may be used as symbols, with the
2868 -- exceptions of "if", "else", "elsif", "end", "and", "or" and "then".
2869 --
2870 -- A symbol declared with this qualifier on the command line replaces
2871 -- a symbol with the same name either in a definition file or specified
2872 -- with a switch -D in the preprocessor data file.
2873 --
2874 -- This qualifier is similar to qualifier /ASSOCIATE of
2875 -- GNAT PREPROCESSING.
2879 -- /NOSYNTAX_ONLY (D)
2880 -- /SYNTAX_ONLY
2881 --
2882 -- Run GNAT in syntax checking only mode. You can check a series of
2883 -- files in a single command, and can use wild cards to specify such a
2884 -- group of files.
2885 --
2886 -- You may use other qualifiers in conjunction with this qualifier. In
2887 -- particular, /LIST and /REPORT_ERRORS=VERBOSE are useful to control the
2888 -- format of any generated error messages.
2889 --
2890 -- The output is simply the error messages, if any. No object file or ALI
2891 -- file is generated by a syntax-only compilation. Also, no units other
2892 -- than the one specified are accessed. For example, if a unit "X" with's
2893 -- a unit "Y", compiling unit "X" in syntax check only mode does not
2894 -- access the source file containing unit "Y".
2895 --
2896 -- Normally, GNAT allows only a single unit in a source file. However,
2897 -- this restriction does not apply in syntax-check-only mode, and it is
2898 -- possible to check a file containing multiple compilation units
2899 -- concatenated together. This is primarily used by the GNAT CHOP
2900 -- command.
2904 -- /TABLE_MULTIPLIER=nnn
2905 --
2906 -- All compiler tables start at nnn times usual starting size.
2910 -- /WRITE_TARGET_DEPENDENT_INFO=file

2922 -- /TRACE_UNITS
2923 -- /NOTRACE_UNITS
2924 --
2925 -- This switch that does for the frontend what /VERBOSE does for the
2926 -- backend. The system prints the name of each unit, either a compilation
2927 -- unit or nested unit, as it is being analyzed.
2931 -- /TREE_OUTPUT
2932 -- /NOTREE_OUTPUT
2933 --
2934 -- Cause GNAT to write the internal tree for a unit to a file (with the
2935 -- filetype ATB for a body or ATS for a spec). This is not normally
2936 -- required, but is used by separate analysis tools. Typically these
2937 -- tools do the necessary compilations automatically, so you should never
2938 -- have to specify this switch in normal operation.
2942 -- /TRY_SEMANTICS
2943 -- /NOTRY_SEMANTICS
2944 --
2945 -- In normal operation mode the compiler first parses the program and
2946 -- determines if there are any syntax errors. If there are, appropriate
2947 -- error messages are generated and compilation is immediately
2948 -- terminated. This qualifier tells GNAT to continue with semantic
2949 -- analysis even if syntax errors have been found. This may enable the
2950 -- detection of more errors in a single run. On the other hand, the
2951 -- semantic analyzer is more likely to encounter some internal fatal

3051 -- FULL Every assignment is checked for validity, so
3052 -- that it is impossible to assign invalid values.
3053 -- The RM specifically allows such assignments,
3054 -- but in this mode, invalid values can never be
3055 -- assigned, and an attempt to perform such an
3056 -- assignment immediately raises Constraint_Error.
3057 -- This behavior is allowed (but not required) by
3058 -- the RM. This mode is intended as a debugging aid,
3059 -- and may be useful in helping to track down
3060 -- uninitialized variables. It may be useful to
3061 -- use this in conjunction with the Normalize_Scalars
3062 -- pragma which attempts to initialize with invalid
3063 -- values where possible.

3280 --
3281 -- In addition to error messages, corresponding to illegalities as
3282 -- defined in the reference manual, the compiler detects two kinds of
3283 -- warning situations. First, the compiler considers some constructs
3284 -- suspicious and generates a warning message to alert you to a possible
3285 -- error. Second, if the compiler detects a situation that is sure to
3286 -- raise an exception at runtime, it generates a warning message.
3287 --
3288 -- You may specify the following keywords to change this behavior.
3289 --
3290 -- DEFAULT (D) The default behavior. This includes the
3291 -- following categories of warnings:
3292 --
3293 -- ADA_COMPATIBILITY
3294 -- ADDRESS_CLAUSE_OVERLAY
3295 -- BIASED_REPRESENTATION

3307 -- VARIABLES_UNINITIALIZED
3308 --
3309 -- as well as all warnings that cannot be
3310 -- individually suppressed.
3311 --
3312 -- ALL Activate all optional warnings.
3313 -- Activates the most commong used optional
3314 -- warning messages. The warnings that are not
3315 -- turned on by this are:
3316 --
3317 -- ADDRESS_CLAUSE_OVERLAY
3318 -- ATOMIC_SYNCHRONIZATION
3319 -- AVOID_GAPS

3335 --
3336 -- All other optional warnings are turned on.
3337 --
3338 -- OPTIONAL Turn on standard optional warnings.
3339 -- This has the same effect as ALL.
3340 --
3341 -- NOALL Suppress all optional errors.
3342 -- Suppresses all optional warning messages
3343 -- including those not activated by ALL.
3344 --
3345 -- NOOPTIONAL Turn off standard optional warnings.
3346 -- This has the same effect as NOALL
3347 --
3348 -- EVERY Activate every optional warning.
3349 -- Activates all optional warnings, including
3350 -- those listed above as exceptions for ALL.
3351 --
3352 -- ALL_GCC Request additional messages from the GCC
3353 -- backend. Most of these are not Ada-relevant.
3354 --
3355 -- UNINITIALIZED Activate warnings for uninitialized
3356 -- variables. This is a GCC option, not an Ada
3357 -- option. You must also specify the /OPTIMIZE
3358 -- qualifier with a value other than NONE (in
3359 -- other words, this option is effective only
3360 -- if optimization is turned on).
3361 --
3362 -- ERRORS Warning messages are to be treated as errors.
3363 -- The warning string still appears, but the
3364 -- warning messages are counted as errors, and
3365 -- prevent the generation of an object file.
3366 --
3367 -- SUPPRESS Completely suppress the output of all warning
3368 -- messages. Same as /NOWARNINGS.
3369 --
3370 -- NORMAL Sets normal warning mode, in which enabled
3371 -- warnings are issued and treated as warnings
3372 -- rather than errors. This is the default mode.
3373 -- It can be used to cancel the effect of an
3374 -- explicit /WARNINGS=SUPPRESS or
3375 -- /WARNINGS=ERRORS. It also cancels the effect
3376 -- of the implicit /WARNINGS=ERRORS that is
3377 -- activated by the use of /STYLE=GNAT.
3378 --
3379 -- TAG_WARNINGS Causes the string [xxx] to be added to
3380 -- warnings that are controlled by the warning
3381 -- switch -gnat??. See below for list of these
3382 -- equivalent switch names.
3383 --
3384 -- NOTAG_WARNINGS Turns off warning tag output (default
3385 -- setting).
3386 --
3387 -- The remaining entries control individual warning categories. If one
3388 -- of these options is preceded by NO (e.g. NOAVOID_GAPS), then the
3389 -- corresponding class of warnings is suppressed. The -gnatwxx tag
3390 -- below the name indicates the non-VMS warning switch option. This is
3391 -- used in the warning tags generated by TAG_WARNINGS (above)
3392 --
3393 -- ADA_COMPATIBILITY Activate warnings for Ada compatibility issues.
3394 -- (-gnatwy) This generates warnings for usages which are
3395 -- legal, but may cause difficulties with later
3396 -- Ada versions (e.g. the use of INTERFACE as an
3397 -- identifier, which is legal in Ada 85, but in
3398 -- Ada 2005, this is a reserved word).
3399 --
3400 -- ATOMIC_SYNCHRONIZATION Activate info msgs for atomic synchronization.
3401 -- (-gnatw.n) This generates information messages when an
3402 -- access to an atomic variable requires the
3403 -- generation of atomic synchronization code.
3404 --
3405 -- AVOIDGAPS Activate warnings for gaps in records.
3406 -- (-gnatw.h) This outputs a warning if a representation
3407 -- clause for a record leaves unallocated bits.
3408 --
3409 -- BAD_FIXED_VALUES Activate warnings on bad fixed values.
3410 -- (-gnatwb) When this is enabled, a fixed-type literal
3411 -- will generate a warning if its value does not
3412 -- correspond to an exact value of the type and
3413 -- is thus subject to rounding.
3414 --
3415 -- BIASED_REPRESENTATION Activate warnings for biased representations.
3416 -- (-gnatw.b) A warning will be generated if a size clause
3417 -- or a component clause forces use of a biased
3418 -- representation (e.g. range 1..5 with size 2).
3419 --
3420 -- CONDITIONALS Activate warnings for conditional expressions
3421 -- (-gnatwc) in tests where the expression is known to
3422 -- be True or False at compile time.
3423 --
3424 -- CONSTANT_VARIABLES Activate warnings on constant variables.
3425 -- (-gnatwk) A warning is output for a variable which could
3426 -- have been declared as a constant.
3427 --
3428 -- DELETED_CODE Activate warning for conditional deleted code.
3429 -- (-gnatwt) This option generates warnings for tracking of
3430 -- code in conditionals (IF and CASE statements)
3431 -- that is detected to be dead code which cannot
3432 -- be executed, and which is removed by the
3433 -- front end. This may be useful for detecting
3434 -- deactivated code in certified applications.
3435 --
3436 -- ELABORATION Activate warnings on missing pragma Elaborate
3437 -- (-gnatwl) and Elaborate_All statements.
3438 --
3439 -- FAILING_ASSERTIONS Activate warnings on failing assertions.
3440 -- (-gnatw.a) Generates a warning for assertions that are
3441 -- sure to fail.
3442 --
3443 -- HIDING Activate warnings on hiding declarations.
3444 -- (-gnatwh) A declaration is considered hiding if it is
3445 -- for a non-overloadable entity, and declares
3446 -- an entity with the same name as some other
3447 -- entity that is directly or use-visible.
3448 --
3449 -- IMPLEMENTATION Activate warnings for a with of an internal
3450 -- (-gnatwi) GNAT implementation unit, defined as any unit
3451 -- from the Ada, Interfaces, GNAT, DEC or System
3452 -- hierarchies that is not documented in the
3453 -- Ada Reference Manual or the GNAT Programmer's
3454 -- Reference Manual. Such units are intended only
3455 -- for internal implementation purposes and may
3456 -- change from version to veresion, and should
3457 -- not be with'ed by user programs.
3458 --
3459 -- IMPLICIT_DEREFERENCE Activate warnings on implicit dereferencing.
3460 -- (-gnatwd) The use of a prefix of an access type in an
3461 -- indexed component, slice, or selected component
3462 -- without an explicit .all will generate a
3463 -- warning. When this warning is enabled, and no
3464 -- warnings of this type are generated, access
3465 -- checks occur only at points where the source
3466 -- program contains an explicit use of .all.
3467 --
3468 -- IMPORT_EXPORT_PRAGMAS Activate warnings on import-export pragmas.
3469 -- (-gnatwx) This generates a warning on an Export or Import
3470 -- pragma when the compiler detects a possible
3471 -- conflict between the Ada and foreign language
3472 -- calling sequences. For example, the use of
3473 -- default parameters in a convention C procedure
3474 -- is dubious because the C compiler cannot supply
3475 -- the proper default, so a warning is issued.
3476 --
3477 -- INEFFECTIVE_INLINE Activate warnings on ineffective Inlines.
3478 -- (-gnatwp) Activates warnings for failure of front end
3479 -- inlining (activated by /INLINE=FULL) to
3480 -- inline a particular call when a pragma Inline
3481 -- applies. There are many reasons for not
3482 -- being able to inline a call, including most
3483 -- commonly that the call is too complex to
3484 -- inline. This warning can also be turned on
3485 -- using /INLINE=FULL.
3486 --
3487 -- INHERITED_ASPECTS Activate info messages for inherited aspects.
3488 -- (-gantw.l) Outputs information messages for tagged types
3489 -- that inherit aspects from a parent.
3490 --
3491 -- LOCAL_RAISE_HANDLING Activate warnings for No_Exception_Propagation.
3492 -- (-gnatw.x) This generates warnings for exception usage
3493 -- when the No_Exception_Propagation restriction
3494 -- is in effect. Warnings are given for implicit
3495 -- or explicit exception raises which are not
3496 -- covered by a local handler, and for exception
3497 -- handlers which do not cover a local raise.
3498 --
3499 -- LOWBOUND_ASSUMED Activate warnings for low bound assumptions.
3500 -- (-gnatww) Outputs warnings if code appears to depend on
3501 -- an assumption about the lower bound of one of
3502 -- the subprogram parameters (for example using
3503 -- S(1 .. 5) instead of S(S'First .. S'First + 4).
3504 --
3505 -- MISSING_COMPONENT_CLAUSES
3506 -- (-gnatw.c) Activate warnings for unrepped component.
3507 -- Generates a warning for a record component
3508 -- which does not have a component clause if
3509 -- at least one component claused is present
3510 -- for some other component of the record.
3511 --
3512 -- MISSING_PARENS Activate warnings for missing parentheses.
3513 -- (-gnatwq) Outputs a warning for cases where parentheses
3514 -- are not used and the result is potential
3515 -- ambiguity from a reader's point of view.
3516 -- For example (not a > b) when a and b are
3517 -- modular means (not (a) > b) and very likely
3518 -- the programmer intended (not (a > b)).
3519 --
3520 -- MODIFIED_UNREF Activate warning for assigned but not read.
3521 -- (-gnatwm) Outputs a warning for variables that are
3522 -- assigned (using an initialization value or an
3523 -- assignment statements) but whose value is
3524 -- never read. The warning is suppressed for
3525 -- volatile variables and also for variables
3526 -- that are renamings of other variables or for
3527 -- which an address clause is given.
3528 --
3529 -- OBJECT_RENAME Activate warnings for non limited objects
3530 -- (-gnatw.r) renaming parameterless functions.
3531 --
3532 -- OBSOLESCENT Activates warnings for calls to subprograms
3533 -- (-gnatwj) marked with pragma Obsolescent and for use of
3534 -- features in Annex J of the Ada Reference
3535 -- Manual. In the case of Annex J, not all
3536 -- features are flagged. In particular use of
3537 -- the renamed packages (like Text_IO), use of
3538 -- package ASCII, and use of the attribute
3539 -- 'Constrained are not flagged, since these are
3540 -- common and would generate many annoying
3541 -- false-positive warnings.
3542 --
3543 -- OUT_PARAM_UNREF Activate warnings on unreferenced OUT params.
3544 -- (-gantw.o) This switch activates warnings for variables
3545 -- that are modified by using them as actuals for
3546 -- a call to a procedure with an out mode formal,
3547 -- where the resulting assigned value is never
3548 -- read. It is applicable in the case where there
3549 -- is more than one out mode formal. If there is
3550 -- only one out mode formal, the warning is issued
3551 -- by default (controlled by UNUSED). The warning
3552 -- is suppressed for volatile variables and also
3553 -- for variables that are renamings of other
3554 -- variables or for which an address clause
3555 -- is given.
3556 --
3557 -- OVERLAPPING_ACTUALS Activate warnings on overlapping actuals.
3558 -- (-gnatw.i) Enables a warning on statically detectable
3559 -- overlapping actuals in a subprogram call,
3560 -- when one of the actuals is an in-out
3561 -- parameter, and the types of the actuals
3562 -- are not by-copy types.
3563 --
3564 -- OVERLAYS Activate warnings for possibly unintended
3565 -- (-gnatwo) initialization effects of defining address
3566 -- clauses that cause one variable to overlap
3567 -- another.
3568 --
3569 -- OVERRIDING_SIZE Activate warning on overridden size clause.
3570 -- (-gnatw.s) Generates a warning if an explicit size clause
3571 -- is overridden by a component clause in a record
3572 -- or a component size in an array.
3573 --
3574 -- PARAMETER_ORDER Activate warnings for suspicious parameter
3575 -- (-gnatw.p) ordering. A warning is generated if positional
3576 -- ordering is used and the actuals match the
3577 -- formal names, but are in the wrong order (e.g.
3578 -- GEN (B, A), when the formals of GEN are A, B.)
3579 -- No warning is generated for named parameters,
3580 -- so GEN (A => B, B => A) would be allowed.
3581 --
3582 -- REDUNDANT Activate warnings for redundant constructs.
3583 -- (-gnatwr) In particular assignments of a variable to
3584 -- itself, and a type conversion that converts
3585 -- an object to its own type.
3586 --
3587 -- REVERSE_BIT_ORDER Activates info messages for reverse bit order.
3588 -- (-gnatw.v) Generates information messages that show the
3589 -- effect of specifying reverse bit order for
3590 -- a record on individual components.
3591 --
3592 -- STANDARD_REDEFINITION Activate warnings on standard redefinition.
3593 -- (-gnatw.k) Generates a warning message if a declaration
3594 -- declares an identifier that matches one that
3595 -- is declared in package Standard (e.g. Float).
3596 --
3597 -- SUSPICIOUS_CONTRACT Activate warnings on suspicious postconditions.
3598 -- (-gnatw.t) This generates warnings if a postcondition for
3599 -- a function does not mention the result, or if
3600 -- a postcondition for a procedure depends only on
3601 -- the entry values of the parameters.
3602 --
3603 -- SUSPICIOUS_MODULUS Warn on suspicious modulus values, for
3604 -- (-gnatw.m) example "mod 7" is suspicious for a size with
3605 -- 7 bits, since it was likely intended to be
3606 -- "mod 2**7". Similarly "mod 32" is considered
3607 -- suspicious, since it was likely intended to
3608 -- be "mod 2**32".
3609 --
3610 -- UNCHECKED_CONVERSIONS Activates warnings on unchecked conversions.
3611 -- (-gnatwz) Causes warnings to be generated for unchecked
3612 -- conversions between types that are known at
3613 -- compile time to have different sizes.
3614 --
3615 -- UNORDERED_ENUMERATION Activate warnings for unordered enumeration.
3616 -- (-gnatw.u) Causes warnings to be generated if for an
3617 -- enumeration type that does not have a pragma
3618 -- Ordered that applies, if a subtype with a
3619 -- range is used, or a comparison other than
3620 -- [in]equality appears for values of the type.
3621 --
3622 -- UNRECOGNIZED_PRAGMAS Activate warnings for unrecognized pragmas.
3623 -- (-gnatwg) Such pragmas are ignored other than generating
3624 -- these warnings.
3625 --
3626 -- UNREFERENCED_FORMALS Activate warnings on unreferenced formals.
3627 -- (-gnatwf) Causes a warning to be generated if a formal
3628 -- parameter is not referenced in the body of
3629 -- the subprogram. Note that the combination
3630 -- UNUSED followed by NOUNREFERENCED_FORMALS
3631 -- has the effect of warning on unreferenced
3632 -- entities other than subprogram formals.
3633 --
3634 -- UNUSED Activates warnings to be generated for entities
3635 -- (-gantwu) that are defined but not referenced, and for
3636 -- units that are with'ed and not referenced. In
3637 -- the case of packages, a warning is also
3638 -- generated if no entities in the package are
3639 -- referenced. This means that if the package
3640 -- is referenced but the only references are in
3641 -- in use clauses or renames declarations, a
3642 -- warning is still generated. A warning is also
3643 -- generated for a generic package that is
3644 -- with'ed but never instantiated. In the case
3645 -- where a package or subprogram body is
3646 -- compiled, and there is a with on the
3647 -- corresponding spec that is only referenced
3648 -- in the body, a warning is also generated,
3649 -- noting the with can be moved to the body.
3650 --
3651 -- VARIABLES_UNINITIALIZED Activates warnings on unassigned variables.
3652 -- (-gnatwv) Causes warnings to be generated when a
3653 -- variable is accessed which may not be
3654 -- properly initialized.
3655 --
3656 -- WARNINGS_OFF_PRAGMAS Activates warnings for pragma Warnings (Off).
3657 -- (-gnatw.w) This generates a warning if the specific string
3658 -- version the pragma is used as a local pragma
3659 -- (i.e. not a configuration pragma) and no
3660 -- warning is suppressed as a result.
3661 --
3662 -- WHY_SPEC_NEEDS_BODY Generates information messages showing why a
3663 -- (-gnatw.y) package specification requires a body.
3664 --
3667 -- NODOC (see /WARNINGS)
3671 -- /NO_BACK_END_WARNINGS
3672 --
3673 -- Inhibit all warning messages of the GCC back-end.
3688 -- /NOWIDE_CHARACTER_ENCODING (D)
3689 -- /WIDE_CHARACTER_ENCODING[=encode-type]
3690 --
3691 -- Specifies the mechanism used to encode wide characters. 'encode-type'
3692 -- is one of the following:
3693 --
3694 -- BRACKETS (D) A wide character is encoded as ["xxxx"] where XXXX
3695 -- are four hexadecimal digits representing the coding
3696 -- ('Pos value) of the character in type
3697 -- Wide_Character. The hexadecimal digits may use upper
3698 -- or lower case letters.
3699 --
3700 -- This notation can also be used for upper half
3701 -- Character values using the format ["xx"] where XX is
3702 -- two hexadecimal digits representing the coding ('Pos
3703 -- value) of the character in type Character (or
3704 -- Wide_Character). The hexadecimal digits may use upper
3705 -- of lower case.
3706 --
3707 -- NONE No wide characters are allowed. Same
3708 -- as /NOWIDE_CHARACTER_ENCODING.
3709 --
3710 -- HEX In this encoding, a wide character is represented by
3711 -- the following five character sequence: ESC a b c d
3712 -- Where 'a', 'b', 'c', and 'd' are the four hexadecimal
3713 -- characters (using uppercase letters) of the wide
3714 -- character code. For example, ESC A345 is used to
3715 -- represent the wide character with code 16#A345#. This
3716 -- scheme is compatible with use of the full
3717 -- Wide_Character set.
3718 --
3719 -- UPPER The wide character with encoding 16#abcd# where the
3720 -- upper bit is on (in other words, "a" is in the range
3721 -- 8-F) is represented as two bytes, 16#ab# and 16#cd#.
3722 -- The second byte may never be a format control
3723 -- character, but is not required to be in the upper
3724 -- half. This method can be also used for shift-JIS or
3725 -- EUC, where the internal coding matches the external
3726 -- coding.
3727 --
3728 -- SHIFT_JIS A wide character is represented by a two-character
3729 -- sequence, 16#ab# and 16#cd#, with the restrictions
3730 -- described for upper-half encoding as described above.
3731 -- The internal character code is the corresponding JIS
3732 -- character according to the standard algorithm for
3733 -- Shift-JIS conversion. Only characters defined in the
3734 -- JIS code set table can be used with this encoding
3735 -- method.
3736 --
3737 -- UTF8 A wide character is represented using
3738 -- UCS Transformation Format 8 (UTF-8) as defined in Annex
3739 -- R of ISO 10646-1/Am.2. Depending on the character
3740 -- value, the representation is a one, two, or three byte
3741 -- sequence:
3742 --
3743 -- 16#0000#-16#007f#: 2#0xxxxxxx#
3744 -- 16#0080#-16#07ff#: 2#110xxxxx# 2#10xxxxxx#
3745 -- 16#0800#-16#ffff#: 2#1110xxxx# 2#10xxxxxx# 2#10xxxxxx#
3746 --
3747 -- where the xxx bits correspond to the left-padded bits
3748 -- of the 16-bit character value. Note that all lower
3749 -- half ASCII characters are represented as ASCII bytes
3750 -- and all upper half characters and other wide characters
3751 -- are represented as sequences of upper-half (The full
3752 -- UTF-8 scheme allows for encoding 31-bit characters as
3753 -- 6-byte sequences, but in this implementation, all UTF-8
3754 -- sequences of four or more bytes length will be treated
3755 -- as illegal).
3756 --
3757 -- EUC A wide character is represented by a two-character
3758 -- sequence 16#ab# and 16#cd#, with both characters being
3759 -- in the upper half. The internal character code is the
3760 -- corresponding JIS character according to the EUC
3761 -- encoding algorithm. Only characters defined in the JIS
3762 -- code set table can be used with this encoding method.
3766 -- NODOC (see /WIDE_CHARACTER_ENCODING)
3770 -- /NOXDEBUG (D)
3771 -- /XDEBUG
3772 --
3773 -- Output expanded source files for source level debugging.
3774 -- The expanded source (see /EXPAND_SOURCE) is written to files
3775 -- with names formed by appending "_DG" to the input file name,
3776 -- The debugging information generated by the /DEBUG qualifier will then

7384 -- /ALL
7385 --
7386 -- Also check the components of the GNAT run time and process the needed

7396 -- specified, the underlying tool gnatsync is called for all the
7397 -- sources of all the Project Files in the project tree.
7401 -- /EXTERNAL_REFERENCE="name=val"
7402 --
7403 -- Specifies an external reference to the project manager. Useful only if
7404 -- /PROJECT_FILE is used.
7405 --
7406 -- Example:
7407 -- /EXTERNAL_REFERENCE="DEBUG=TRUE"
7411 -- /FILES=filename

7442 --
7443 -- MEDIUM A small number of messages are output.
7444 --
7445 -- HIGH A great number of messages are output, most of them not
7446 -- being useful for the user.
7450 -- /PROJECT_FILE=filename
7451 --
7452 -- Specifies the main project file to be used. The project files rooted
7453 -- at the main project file will be parsed before the invocation of the
7454 -- gnatcheck. The source directories to be searched will be communicated
7455 -- to gnatcheck through logical name ADA_PRJ_INCLUDE_FILE.

7461 --
7462 -- Work quietly, only output warnings and errors.
7466 -- /SUBDIRS=dir
7467 --
7468 -- The actual directories (object, exec, library, ...) are subdirectories

7470 -- does not exist, it is created automatically.
7474 -- /NOVERBOSE (D)
7475 -- /VERBOSE
7476 --
7477 -- The version number and copyright notice are output, as well as exact
7478 -- copies of the gnat1 commands spawned to obtain the chop control
7479 -- information.

7498 -- Options may be one of the following:
7499 --
7500 -- MEDIUM (D)
7501 -- SHORT
7502 -- FULL
7506 --

7549 -- /ADD_PROJECT_SEARCH_PATH=(directory[,...])
7550 --
7551 -- Add directories to the project search path.
7555 -- /NOALL_FILES (D)
7556 -- /ALL_FILES
7557 --
7558 -- If this switch is present, FIND and XREF will parse the read-only
7559 -- files found in the library search path. Otherwise, these files will
7560 -- be ignored. This option can be used to protect Gnat sources or your
7561 -- own libraries from being parsed, thus making FIND and XREF much
7562 -- faster, and their output much smaller.
7566 -- /NODERIVED_TYPES (D)
7567 -- /DERIVED_TYPES
7568 --
7569 -- Output the parent type reference for each matching derived types.
7573 -- /EXTERNAL_REFERENCE="name=val"
7574 --
7575 -- Specifies an external reference to the project manager. Useful only if
7576 -- /PROJECT_FILE is used.

7590 -- /NOFULL_PATHNAME (D)
7591 -- /FULL_PATHNAME
7592 --
7593 -- If this switch is set, the output file names will be preceded by their
7594 -- directory (if the file was found in the search path). If this switch
7595 -- is not set, the directory will not be printed.
7599 -- /NOIGNORE_LOCALS (D)
7600 -- /IGNORE_LOCALS
7601 --
7602 -- If this switch is set, information is output only for library-level
7603 -- entities, ignoring local entities. The use of this switch may
7604 -- accelerate FIND and XREF.
7613 -- /MESSAGES_PROJECT_FILE[=messages-option]
7614 --
7615 -- Specifies the "verbosity" of the parsing of project files.
7616 -- messages-option may be one of the following:

7618 -- DEFAULT (D) No messages are output if there is no error or warning.
7619 --
7620 -- MEDIUM A small number of messages are output.
7621 --
7622 -- HIGH A great number of messages are output, most of them not
7623 -- being useful for the user.
7627 -- /NOSTD_INCLUDES
7628 --
7629 -- Do not look for sources in the system default directory.
7633 -- /NOSTD_LIBRARIES
7634 --

7639 -- /OBJECT_SEARCH=(directory,...)
7640 --
7641 -- When searching for library and object files, look in the specified
7642 -- directories. The order in which library files are searched is the same
7643 -- as for MAKE.
7647 -- /PROJECT=file
7648 --
7649 -- Specify a project file to use. By default, FIND and XREF will try to
7650 -- locate a project file in the current directory.
7651 --
7652 -- If a project file is either specified or found by the tools, then the
7653 -- content of the source directory and object directory lines are added
7654 -- as if they had been specified respectively by /SOURCE_SEARCH and
7655 -- /OBJECT_SEARCH.
7659 -- /PROJECT_FILE=filename
7660 --
7661 -- Specifies the main project file to be used. The project files rooted
7662 -- at the main project file will be parsed before doing any processing.
7663 -- The source and object directories to be searched will be communicated
7664 -- to gnatxref through logical names ADA_PRJ_INCLUDE_FILE and
7665 -- ADA_PRJ_OBJECTS_FILE.
7669 -- /SEARCH=(directory,...)
7670 --
7671 -- Equivalent to:
7672 -- /OBJECT_SEARCH=(directory,...) /SOURCE_SEARCH=(directory,...)
7676 -- /SOURCE_SEARCH=(directory,...)
7677 --
7678 -- When looking for source files also look in the specified directories.
7679 -- The order in which source file search is undertaken is the same as for
7680 -- MAKE.
7684 -- /SUBDIRS=dir
7685 --
7686 -- The actual directories (object, exec, library, ...) are subdirectories
