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
452 -- communicated to the binder through logical names ADA_PRJ_INCLUDE_FILE
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)

1258 --
1259 -- Allows GNAT to recognize the full range of Ada 2005 constructs.
1260 -- Equivalent to /05 (/2005 is the preferred usage).
1264 -- /05 (D)

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
1431 --
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",

1739 -- to represent additional characters. This includes
1740 -- extended letters used by European languages, such as
1741 -- the umlaut used in German.
1742 --
1743 -- You may use any of these extended characters freely

1764 --
1765 -- PC850 This code page (850) is a modification of 437 extended

1769 -- lower case equivalence.
1770 --

1821 --
1822 -- Note that this qualifier is intended only for helping to diagnose
1823 -- illegal programs when the compiler fails. It disconnects many of the

1825 -- cause malfunction of pragma Warnings.
1838 -- /NOINLINE (D)
1839 -- /INLINE[=keyword]
1840 --
1841 -- Selects the level of inlining for your program. In the absence of this
1842 -- qualifier, GNAT does not attempt inlining across units and does not
1843 -- need to access the bodies of subprograms for which "pragma Inline" is
1844 -- specified if they are not in the current unit.
1845 --
1846 -- The supported keywords are as follows:
1847 --
1848 -- PRAGMA (D) Recognize and process "Inline" pragmas. However,
1849 -- for the inlining to actually occur, optimization
1850 -- must be enabled. This enables inlining across unit
1851 -- boundaries, that is, inlining a call in one unit of
1852 -- a subprogram declared in a with'ed unit. The compiler
1853 -- will access these bodies, creating an extra source
1854 -- dependency for the resulting object file, and where
1855 -- possible, the call will be inlined.
1856 --
1857 -- This qualifier also turns on full optimization and
1858 -- requests GNAT to try to attempt automatic inlining
1859 -- of small subprograms within a unit.
1860 --
1861 -- Specifying /OPTIMIZE=NONE will disable the main effect
1862 -- of this qualifier, but you may specify other
1863 -- optimization options, to get either lower
1864 -- (/OPTIMIZE=SOME) or higher (/OPTIMIZE=UNROLL_LOOPS)
1865 -- levels of optimization.
1866 --
1867 -- PRAGMA_LEVEL_1

1870 --
1871 -- PRAGMA_LEVEL_2
1872 -- Direct control of the level of "Inline" pragmas
1873 -- optimization with full inlining across modules.
1874 --
1875 -- FULL Front end inlining. The front end inlining activated
1876 -- by this switch is generally more extensive, and quite
1877 -- often more effective than the standard PRAGMA inlining
1878 -- mode. It will also generate additional dependencies.
1879 --
1880 -- SUPPRESS Suppresses all inlining, even if other optimization
1881 -- or inlining switches are set.
1885 -- NODOC (see /INLINE)
1890 -- /NO_INTERSPERSE_SOURCE (D)
1891 -- /INTERSPERSE_SOURCE

1938 -- qualifier is also present.
1942 -- /MAPPING_FILE=file_name
1943 --
1944 -- Use mapping file file_name
1945 --
1946 -- A mapping file is a way to communicate to the compiler two mappings:
1947 -- from unit names to file names (without any directory information) and
1948 -- from file names to path names (with full directory information).
1949 -- These mappings are used by the compiler to short-circuit the path
1950 -- search.
1951 --
1952 -- The use of mapping files is not required for correct operation of the
1953 -- compiler, but mapping files can improve efficiency, particularly when
1954 -- sources are read over a slow network connection. In normal operation,
1955 -- you need not be concerned with the format or use of mapping files,
1956 -- and /MAPPING_FILE is not a qualifier that you would use explicitly.
1957 -- It is intended only for use by automatic tools such as GNAT MAKE
1958 -- running under the project file facility. The description here of the
1959 -- format of mapping files is provided for completeness and for possible
1960 -- use by other tools.
1961 --
1962 -- A mapping file is a sequence of sets of three lines. In each set, the
1963 -- first line is the unit name, in lower case, with "%s" appended for
1964 -- specifications and "%b" appended for bodies; the second line is the
1965 -- file name; and the third line is the path name.
1966 --
1967 -- Example:
1968 --
1969 -- main%b
1970 -- main.2_ada
1971 -- /gnat/project1/sources/main.2_ada
1972 --
1973 -- When qualifier ?MAPPING_FILE is specified, the compiler will create in
1974 -- memory the two mappings from the specified file. If there is any
1975 -- problem (non existent file, truncated file or duplicate entries),
1976 -- no mapping will be created.
1977 --
1978 -- Several /MAPPING_FILE qualifiers may be specified; however, only the
1979 -- last one on the command line will be taken into account.
1980 --
1981 -- When using a project file, GNAT MAKE creates a temporary mapping file
1982 -- and communicates it to the compiler using this switch.
1987 -- /MAX_INSTANTIATIONS=nnn
1988 --
1989 -- Specify the maximum number of instantiations permitted. The default
1990 -- value is 8000, which is probably enough for all programs except those
1991 -- containing some kind of runaway unintended instantiation loop.
2000 -- /MESSAGES_PROJECT_FILE[=messages-option]
2001 --
2002 -- Specifies the "verbosity" of the parsing of project files.
2003 -- messages-option may be one of the following:
2004 --
2005 -- DEFAULT (D) No messages are output if there is no error or warning.
2006 --
2007 -- MEDIUM A small number of messages are output.
2008 --
2009 -- HIGH A great number of messages are output, most of them not
2010 -- being useful for the user.
2014 -- /MULTI_UNIT_INDEX=nnn
2015 --
2016 -- Specify the index of the unit to compile in a multi-unit source file.
2020 -- /MAX_NESTING=nnn
2021 --
2022 -- Set maximum level of nesting of constructs (including subprograms,
2023 -- loops, blocks, packages, and conditionals).
2024 -- The level of nesting must not exceed the given value nnn.
2025 -- A value of zero disable this style check (not enabled by default).
2029 -- /NO_GNAT_ADC
2030 --
2031 -- Cause the compiler to ignore any configuration pragmas file GNAT.ADC
2032 -- in the default directory. Implied by qualifier /PROJECT_FILE.
2033 -- Often used in conjunction with qualifier /CONFIGURATION_PRAGMAS_FILE.
2037 -- /NOLOAD
2038 --
2039 -- Cause the compiler to operate in semantic check mode with full
2040 -- checking for all illegalities specified in the reference manual, but
2041 -- without generation of any source code (no object or ALI file
2042 -- generated).
2043 --
2044 -- Since dependent files must be accessed, you must follow the GNAT
2045 -- semantic restrictions on file structuring to operate in this mode:
2046 --
2047 -- o The needed source files must be accessible.
2048 -- o Each file must contain only one compilation unit.
2049 -- o The file name and unit name must match.
2050 --
2051 -- The output consists of error messages as appropriate. No object file
2052 -- or ALI file is generated. The checking corresponds exactly to the
2053 -- notion of legality in the Ada reference manual.
2054 --
2055 -- Any unit can be compiled in semantics-checking-only mode, including
2056 -- units that would not normally be compiled (generic library units,
2057 -- subunits, and specifications where a separate body is present).
2061 -- /NOSTD_INCLUDES
2062 --
2063 -- Do not look in the default directory for source files of the runtime.
2067 -- /NOSTD_LIBRARIES
2068 --
2069 -- Do not look for library files in the system default directory.
2073 -- /NOWARNING_PRAGMAS
2074 --
2075 -- Causes all Warnings pragmas to be ignored. Useful to check if the
2076 -- program has obsolete warnings pragmas that are hiding problems.
2095 -- /NOOPTIMIZE (D)
2096 -- /OPTIMIZE[=(keyword[,...])]
2097 --
2098 -- Selects the level of optimization for your program. The supported
2099 -- keywords are as follows:
2100 --
2101 -- ALL (D) Perform most optimizations, including those that
2102 -- may be expensive.
2103 --
2104 -- NONE Do not do any optimizations. Same as /NOOPTIMIZE.
2105 --
2106 -- SOME Perform some optimizations, but omit ones that
2107 -- are costly in compilation time.
2108 --
2109 -- SPACE Optimize space usage
2110 --
2111 -- DEVELOPMENT Same as SOME.
2112 --
2113 -- INLINING Full optimization, and also attempt automatic inlining
2114 -- of small subprograms within a unit
2115 --
2116 -- UNROLL_LOOPS Try to unroll loops. This keyword may be specified
2117 -- with any keyword above other than NONE. Loop
2118 -- unrolling usually, but not always, improves the
2119 -- performance of programs.
2120 --
2121 -- NO_STRICT_ALIASING
2122 -- Suppress aliasing analysis. When optimization is
2123 -- enabled (ALL or SOME above), the compiler assumes
2124 -- that pointers do in fact point to legitimate values
2125 -- of the pointer type (allocated from the proper pool).
2126 -- If this assumption is violated, e.g. by the use of
2127 -- unchecked conversion, then it may be necessary to
2128 -- suppress this assumption using this keyword (which
2129 -- may be specified only in conjunction with any
2130 -- keyword above, other than NONE).
2134 -- NODOC (see /OPTIMIZE)
2138 -- /OUTPUT_FILE=fname
2139 --
2140 -- This has the same effect as /LIST except that the output is written
2141 -- to a file instead of to standard output. If the given fname
2142 -- does not start with a period, then it is the full name of the file
2143 -- to be written. If fname starts with a period, the name of the file
2144 -- is the concatenation of to the name of the file being compiled with
2145 -- fname where the period is replace by an underline. For example, if
2146 -- file xyz.adb is compiled with -gnatl=.lst, then the output is written
2147 -- to file xyz.adb_lst.
2151 -- /OVERFLOW_CHECKS=nn
2152 --
2153 -- Set default overflow cheecking mode. If nn is a single digit, in the
2154 -- range 0-3, it sets the overflow checking mode for all expressions,

2156 --
2157 -- 1 all intermediate computations done using base type (STRICT)
2158 -- 2 minimize intermediate overflows (MINIMIZED)
2159 -- 3 eliminate intermediate overflows (ELIMINATED)
2160 --
2161 -- Otherwise nn can be two digits, both 1-3, and in this case the first
2162 -- digit sets the mode (using the above code) for expressions outside an
2163 -- assertion, and the second digit sets the mode for expressions within
2164 -- an assertion.
2168 -- /NOPARAMETER_VALIDITY_CHECK (D)
2169 -- /PARAMETER_VALIDITY_CHECK
2170 --
2171 -- Check validity of subprogram parameters.
2182 -- /POINTER_SIZE=64 (D)
2183 -- /POINTER_SIZE[=(keyword[,...])]
2184 --
2185 -- Change how pointers and descriptors are allocated. The following
2186 -- keywords are supported:

2190 -- Convention_C and generate 64bit descriptors for
2191 -- Descriptor mechanisms for calling imported
2192 -- subprograms and accept both 64bit and 32bit
2193 -- descriptors for calls to exported subprograms.
2194 --
2195 -- LONG Equivalent to option 64.
2196 --
2197 -- 32 Allocate all heap pointers in 32bit space and

2253 -- /NOREPORT_ERRORS (D)
2254 -- /REPORT_ERRORS[=(keyword[,...])]
2255 --
2256 -- Change the way errors are reported. The following keywords are
2257 -- supported:
2258 --
2259 -- VERBOSE (D) Verbose mode. Full error output with source lines
2260 -- to SYS$OUTPUT.
2261 --
2262 -- BRIEF Generate the brief format error messages to
2263 -- SYS$OUTPUT as well as the verbose format message or
2264 -- full listing.
2265 --
2266 -- FULL Normally, the compiler suppresses error messages that
2267 -- are likely to be redundant. This keyword causes all
2268 -- error messages to be generated. One particular effect
2269 -- is for the case of references to undefined variables.
2270 -- If a given variable is referenced several times, the
2271 -- normal format of messages produces one error. With
2272 -- FULL, each undefined reference produces a separate
2273 -- error message.
2274 --
2275 -- IMMEDIATE Normally, the compiler saves up error messages and
2276 -- generates them at the end of compilation in proper
2277 -- sequence. This keyword causes error messages to be
2278 -- generated as soon as they are detected. The use of
2279 -- IMMEDIATE usually causes error messages to be
2280 -- generated out of sequence. Use it when the compiler
2281 -- blows up due to an internal error. In this case, the
2282 -- error messages may be lost. Sometimes blowups are
2283 -- the result of mishandled error messages, so you may
2284 -- want to run with this keyword to determine whether
2285 -- any error messages were generated.
2286 --
2287 -- DEFAULT Turn off VERBOSE and BRIEF. Same as /NOREPORT_ERRORS.
2291 -- NODOC (see /REPORT_ERRORS)

2315 -- /REPRESENTATION_INFO[=(keyword[,...])]
2316 --
2317 -- This qualifier controls output from the compiler of a listing showing

2319 --
2320 -- ARRAYS (D) Size and alignment information is listed for
2321 -- declared array and record types.
2322 --
2323 -- ARRAYS_FILE Similar to ARRAYS, but the output is to a file
2324 -- with the name 'file_rep' where 'file' is the name

2336 --
2337 -- SYMBOLIC Symbolic expression information for values that

2343 --
2344 -- MECHANISMS List convention and argument passing mechanisms

2366 -- /SCO_OUTPUT
2367 --
2368 -- Controls the output of SCO (Source Coverage Obligation) information
2369 -- in the generated ALI file. This information is used by advanced source

2513 -- /NOSTYLE_CHECKS (D)
2514 -- /STYLE_CHECKS[=(keyword,[...])]
2515 --
2516 -- Normally, GNAT permits any code layout consistent with the reference
2517 -- manual requirements. This qualifier imposes style checking on the
2518 -- input source code. The following keywords are supported:
2519 --
2520 -- ALL_BUILTIN (D) Equivalent to the following list of options:
2521 -- 3, ATTRIBUTE, BLANKS, COMMENTS2, END, VTABS,
2522 -- HTABS, IF_THEN, KEYWORD, LAYOUT, LINE_LENGTH,
2523 -- PRAGMA, REFERENCES, SPECS, TOKEN.
2524 --
2525 -- 1 .. 9 Specify indentation level from 1 to 9.
2526 -- The general style of required indentation is as
2527 -- specified by the examples in the Ada Reference
2528 -- Manual. Full line comments must be aligned with
2529 -- the -- starting on a column that is a multiple
2530 -- of the alignment level.
2531 --
2532 -- ATTRIBUTE Check attribute casing.
2533 -- Attribute names, including the case of keywords
2534 -- such as digits used as attributes names,
2535 -- must be written in mixed case, that is,
2536 -- the initial letter and any letter following an
2537 -- underscore must be uppercase.
2538 -- All other letters must be lowercase.
2539 --
2540 -- ARRAY_INDEXES Check indexes of array attributes.
2541 -- For array attributes First, Last, Range,
2542 -- or Length, the index number must be omitted
2543 -- for one-dimensional arrays and is required
2544 -- for multi-dimensional arrays.
2545 --
2546 -- BLANKS Blanks not allowed at statement end.
2547 -- Trailing blanks are not allowed at the end of
2548 -- statements. The purpose of this rule, together
2549 -- with option HTABS (no horizontal tabs), is to
2550 -- enforce a canonical format for the use of
2551 -- blanks to separate source tokens.
2552 --
2553 -- COMMENTS2 Check comments.
2554 -- COMMENTS Comments must meet the following set of rules:
2555 --
2556 -- * The "--" that starts the column must either
2557 -- start in column one, or else at least one
2558 -- blank must precede this sequence.
2559 --
2560 -- * Comments that follow other tokens on a line
2561 -- must have at least one blank following the
2562 -- "--" at the start of the comment.
2563 --
2564 -- * Full line comments must have two blanks
2565 -- following the "--" that starts the comment,
2566 -- with the following exceptions.
2567 --
2568 -- * A line consisting only of the "--"
2569 -- characters, possibly preceded by blanks is
2570 -- permitted.
2571 --
2572 -- * A comment starting with "--x" where x is
2573 -- a special character is permitted. This
2574 -- allows proper processing of the output
2575 -- generated by specialized tools including
2576 -- gnatprep (where --! is used) and the SPARK
2577 -- annotation language (where --# is used).
2578 -- For the purposes of this rule, a special
2579 -- character is defined as being in one of the
2580 -- ASCII ranges 16#21#..16#2F# or
2581 -- 16#3A#..16#3F#.
2582 --
2583 -- * A line consisting entirely of minus signs,
2584 -- possibly preceded by blanks, is permitted.
2585 -- This allows the construction of box
2586 -- comments where lines of minus signs are
2587 -- used to form the top and bottom of the box.
2588 --
2589 -- * If a comment starts and ends with "--" is
2590 -- permitted as long as at least one blank
2591 -- follows the initial "--". Together with
2592 -- the preceding rule, this allows the
2593 -- construction of box comments, as shown in
2594 -- the following example:
2595 --
2596 -- ---------------------------
2597 -- -- This is a box comment --
2598 -- ---------------------------
2599 --
2600 -- COMMENTS1 Check comments (single space).
2601 -- Like COMMENTS2, but the -- of a comment only
2602 -- requires one or more spaces following, instead
2603 -- of two or more spaces.
2604 --
2605 -- DOS_LINE_ENDINGS Check that no DOS line terminators are present
2606 -- All lines must be terminated by a single
2607 -- ASCII.LF character. In particular the DOS line
2608 -- terminator sequence CR / LF is not allowed).
2609 --
2610 -- END Check end/exit labels.
2611 -- Optional labels on end statements ending
2612 -- subprograms and on exit statements exiting
2613 -- named loops, are required to be present.
2614 --
2615 -- GNAT Enforces a set of style conventions that
2616 -- match the style used in the GNAT source code.
2617 -- This maybe useful when developing code that
2618 -- is eventually intended to be incorporated into
2619 -- GNAT. For further details, see GNAT sources.
2620 --
2621 -- HTABS No horizontal tabs.
2622 -- Horizontal tab characters are not permitted in
2623 -- the source text. Together with the BLANKS
2624 -- (no blanks at end of line) option, this
2625 -- enforces a canonical form for the use of blanks
2626 -- to separate source tokens.
2627 --
2628 -- IF_THEN Check if-then layout.
2629 -- The keyword then must appear either on the
2630 -- same line as the corresponding if, or on a line
2631 -- on its own, lined up under the if with at least
2632 -- one non-blank line in between containing all or
2633 -- part of the condition to be tested.
2634 --
2635 -- KEYWORD Check keyword casing.
2636 -- All keywords must be in lower case (with the
2637 -- exception of keywords such as digits used as
2638 -- attribute names to which this check does not
2639 -- apply).
2640 --
2641 -- LAYOUT Check layout.
2642 -- Layout of statement and declaration constructs
2643 -- must follow the recommendations in the Ada
2644 -- Reference Manual, as indicated by the form of
2645 -- the syntax rules. For example an else keyword
2646 -- must be lined up with the corresponding if
2647 -- keyword.
2648 --
2649 -- There are two respects in which the style rule
2650 -- enforced by this check option are more liberal
2651 -- than those in the Ada Reference Manual.
2652 -- First in the case of record declarations,
2653 -- it is permissible to put the record keyword on
2654 -- the same line as the type keyword, and then
2655 -- the end in end record must line up under type.
2656 -- For example, either of the following two
2657 -- layouts is acceptable:
2658 --
2659 -- type q is record
2660 -- a : integer;
2661 -- b : integer;
2662 -- end record;
2663 --
2664 -- type q is
2665 -- record
2666 -- a : integer;
2667 -- b : integer;
2668 -- end record;
2669 --
2670 -- Second, in the case of a block statement,
2671 -- a permitted alternative is to put the block
2672 -- label on the same line as the declare or begin
2673 -- keyword, and then line the end keyword up under
2674 -- the block label. For example both the following
2675 -- are permitted:
2676 --
2677 --
2678 --
2679 -- Block : declare
2680 -- A : Integer := 3;
2681 -- begin
2682 -- Proc (A, A);
2683 -- end Block;
2684 --
2685 -- Block :
2686 -- declare
2687 -- A : Integer := 3;
2688 -- begin
2689 -- Proc (A, A);
2690 -- end Block;
2691 --
2692 -- The same alternative format is allowed for
2693 -- loops. For example, both of the following are
2694 -- permitted:
2695 --
2696 --
2697 --
2698 -- Clear : while J < 10 loop
2699 -- A (J) := 0;
2700 -- end loop Clear;
2701 --
2702 -- Clear :
2703 -- while J < 10 loop
2704 -- A (J) := 0;
2705 -- end loop Clear;
2706 --
2707 --
2708 --
2709 -- LINE_LENGTH Check maximum line length.
2710 -- The length of source lines must not exceed 79
2711 -- characters, including any trailing blanks
2712 -- The value of 79 allows convenient display on
2713 -- an 80 character wide device or window, allowing
2714 -- for possible special treatment of 80 character
2715 -- lines.
2716 --
2717 -- NONE Clear any previously set style checks.
2718 --
2719 -- ORDERED_SUBPROGRAMS Check order of subprogram bodies.
2720 -- All subprogram bodies in a given scope (e.g.
2721 -- a package body) must be in alphabetical order.
2722 -- The ordering rule uses normal Ada rules for
2723 -- comparing strings, ignoring casing of letters,
2724 -- except that if there is a trailing numeric
2725 -- suffix, then the value of this suffix is used
2726 -- in the ordering (e.g. Junk2 comes before
2727 -- Junk10).
2728 --
2729 -- OVERRIDING_INDICATORS Check that overriding subprograms are
2730 -- explicitly marked as such. The declaration of
2731 -- a primitive operation of a type extension that
2732 -- overrides an inherited operation must carry
2733 -- an overriding indicator.
2734 --
2735 -- PRAGMA Check pragma casing.
2736 -- Pragma names must be written in mixed case,
2737 -- that is, the initial letter and any letter
2738 -- following an underscore must be uppercase.
2739 -- All other letters must be lowercase.
2740 --
2741 -- REFERENCES Check references.
2742 -- All identifier references must be cased in the
2743 -- same way as the corresponding declaration.
2744 -- No specific casing style is imposed on
2745 -- identifiers. The only requirement is for
2746 -- consistency of references with declarations.
2747 --
2748 -- SPECS Check separate specs.
2749 -- Separate declarations ("specs") are required
2750 -- for subprograms (a body is not allowed to serve
2751 -- as its own declaration). The only exception is
2752 -- that parameterless library level procedures are
2753 -- not required to have a separate declaration.
2754 -- This exception covers the most frequent form of
2755 -- main program procedures.
2756 --
2757 -- STANDARD_CASING Check casing of entities in Standard.
2758 -- Any identifier from Standard must be cased to
2759 -- match the presentation in the Ada Reference
2760 -- Manual (for example, Integer and ASCII.NUL).
2761 --
2762 -- TOKEN Check token spacing.
2763 -- The following token spacing rules are enforced:
2764 --
2765 -- * The keywords abs and not must be followed
2766 -- by a space.
2767 --
2768 -- * The token => must be surrounded by spaces.
2769 --
2770 -- * The token <> must be preceded by a space or
2771 -- a left parenthesis.
2772 --
2773 -- * Binary operators other than ** must be
2774 -- surrounded by spaces. There is no
2775 -- restriction on the layout of the ** binary
2776 -- operator.
2777 --
2778 -- * Colon must be surrounded by spaces.
2779 --
2780 -- * Colon-equal (assignment) must be surrounded
2781 -- by spaces.
2782 --
2783 -- * Comma must be the first non-blank character
2784 -- on the line, or be immediately preceded by
2785 -- a non-blank character, and must be followed
2786 -- by a space.
2787 --
2788 -- * If the token preceding a left paren ends
2789 -- with a letter or digit, then a space must
2790 -- separate the two tokens.
2791 --
2792 -- * A right parenthesis must either be the
2793 -- first non-blank character on a line, or it
2794 -- must be preceded by a non-blank character.
2795 --
2796 -- * A semicolon must not be preceded by
2797 -- a space, and must not be followed by
2798 -- a non-blank character.
2799 --
2800 -- * A unary plus or minus may not be followed
2801 -- by a space.
2802 --
2803 -- * A vertical bar must be surrounded by
2804 -- spaces.
2805 --
2806 -- In the above rules, appearing in column one is
2807 -- always permitted, that is, counts as meeting
2808 -- either a requirement for a required preceding
2809 -- space, or as meeting a requirement for no
2810 -- preceding space.
2811 --
2812 -- Appearing at the end of a line is also always
2813 -- permitted, that is, counts as meeting either
2814 -- a requirement for a following space,
2815 -- or as meeting a requirement for no following
2816 -- space.
2817 --
2818 -- UNNECESSARY_BLANK_LINES
2819 -- Check for unnecessary blank lines.
2820 -- A blank line is considered unnecessary if it
2821 -- appears at the end of the file, or if more
2822 -- than one blank line occurs in sequence.
2823 --
2824 -- VTABS No form feeds or vertical tabs.
2825 -- Form feeds or vertical tab characters are not
2826 -- permitted in the source text.
2827 --
2828 -- XTRA_PARENS Check for the use of an unnecessary extra
2829 -- level of parentheses (C - style) around
2830 -- conditions in if statements, while statements
2831 -- and exit statements.
2835 -- NODOC (see /STYLE_CHECKS)
2839 -- /SUBDIRS=dir
2840 --
2841 -- The actual directories (object, exec, library, ...) are subdirectories
2842 -- of the directory specified in the project file. If the subdirectory
2843 -- does not exist, it is created automatically.
2847 -- /SYMBOL_PREPROCESSING="symbol=value"
2848 --
2849 -- Define or redefine a preprocessing symbol, associated with value.
2850 -- If "=value" is not specified, then the value of the symbol is True.
2851 -- A symbol is an identifier, following normal Ada (case-insensitive)
2852 -- rules for its syntax, and value is any sequence (including an empty
2853 -- sequence) of characters from the set (letters, digits, period,
2854 -- underline). Ada reserved words may be used as symbols, with the
2855 -- exceptions of "if", "else", "elsif", "end", "and", "or" and "then".
2856 --
2857 -- A symbol declared with this qualifier on the command line replaces
2858 -- a symbol with the same name either in a definition file or specified
2859 -- with a switch -D in the preprocessor data file.
2860 --
2861 -- This qualifier is similar to qualifier /ASSOCIATE of
2862 -- GNAT PREPROCESSING.
2866 -- /NOSYNTAX_ONLY (D)
2867 -- /SYNTAX_ONLY
2868 --
2869 -- Run GNAT in syntax checking only mode. You can check a series of
2870 -- files in a single command, and can use wild cards to specify such a
2871 -- group of files.
2872 --
2873 -- You may use other qualifiers in conjunction with this qualifier. In
2874 -- particular, /LIST and /REPORT_ERRORS=VERBOSE are useful to control the
2875 -- format of any generated error messages.
2876 --
2877 -- The output is simply the error messages, if any. No object file or ALI
2878 -- file is generated by a syntax-only compilation. Also, no units other
2879 -- than the one specified are accessed. For example, if a unit "X" with's
2880 -- a unit "Y", compiling unit "X" in syntax check only mode does not
2881 -- access the source file containing unit "Y".
2882 --
2883 -- Normally, GNAT allows only a single unit in a source file. However,
2884 -- this restriction does not apply in syntax-check-only mode, and it is
2885 -- possible to check a file containing multiple compilation units
2886 -- concatenated together. This is primarily used by the GNAT CHOP
2887 -- command.
2891 -- /TABLE_MULTIPLIER=nnn
2892 --
2893 -- All compiler tables start at nnn times usual starting size.
2897 -- /WRITE_TARGET_DEPENDENT_INFO=file

2909 -- /TRACE_UNITS
2910 -- /NOTRACE_UNITS
2911 --
2912 -- This switch that does for the frontend what /VERBOSE does for the
2913 -- backend. The system prints the name of each unit, either a compilation
2914 -- unit or nested unit, as it is being analyzed.
2918 -- /TREE_OUTPUT
2919 -- /NOTREE_OUTPUT
2920 --
2921 -- Cause GNAT to write the internal tree for a unit to a file (with the
2922 -- filetype ATB for a body or ATS for a spec). This is not normally
2923 -- required, but is used by separate analysis tools. Typically these
2924 -- tools do the necessary compilations automatically, so you should never
2925 -- have to specify this switch in normal operation.
2929 -- /TRY_SEMANTICS
2930 -- /NOTRY_SEMANTICS
2931 --
2932 -- In normal operation mode the compiler first parses the program and
2933 -- determines if there are any syntax errors. If there are, appropriate
2934 -- error messages are generated and compilation is immediately
2935 -- terminated. This qualifier tells GNAT to continue with semantic
2936 -- analysis even if syntax errors have been found. This may enable the
2937 -- detection of more errors in a single run. On the other hand, the
2938 -- semantic analyzer is more likely to encounter some internal fatal

3021 -- /VALIDITY_CHECKING[=(keyword,[...])]
3022 --
3023 -- Control level of validity checking.

3344 --
3345 -- NOIMPLEMENTATION Disables warnings for a with of an internal
3346 -- GNAT implementation unit.
3347 --
3348 -- INEFFECTIVE_INLINE Activate warnings on ineffective pragma Inlines
3349 -- Activates warnings for failure of front end
3350 -- inlining (activated by /INLINE=FULL) to inline
3351 -- a particular call. There are many reasons for
3352 -- not being able to inline a call, including most
3353 -- commonly that the call is too complex to
3354 -- inline. This warning can also be turned on
3355 -- using /INLINE=FULL.
3356 --
3357 -- NOINEFFECTIVE_INLINE Suppress warnings on ineffective pragma Inlines
3358 -- Suppresses warnings on ineffective pragma
3359 -- Inlines. If the inlining mechanism cannot

3374 -- are not used and the result is potential
3375 -- ambiguity from a reader's point of view.
3376 -- For example (not a > b) when a and b are
3377 -- modular means (not (a) > b) and very likely
3378 -- the programmer intended (not (a > b)).
3379 --
3380 -- NOMISSING_PARENS
3381 -- Suppress warnings for cases where parentheses
3382 -- are not used and the result is potential
3383 -- ambiguity from a reader's point of view.

3385 -- MODIFIED_UNREF Activates warnings for variables that are
3386 -- assigned (using an initialization value or with
3387 -- one or more assignment statements) but whose
3388 -- value is never read. The warning is suppressed
3389 -- for volatile variables and also for variables
3390 -- that are renamings of other variables or for
3391 -- which an address clause is given. This warning
3392 -- can also be turned on using /WARNINGS/OPTIONAL.
3393 --
3394 -- NOMODIFIED_UNREF Disables warnings for variables that are
3395 -- assigned or initialized, but never read.
3396 --
3397 -- NORMAL Sets normal warning mode, in which enabled
3398 -- warnings are issued and treated as warnings
3399 -- rather than errors. This is the default mode.
3400 -- It can be used to cancel the effect of an
3401 -- explicit /WARNINGS=SUPPRESS or
3402 -- /WARNINGS=ERRORS. It also cancels the effect
3403 -- of the implicit /WARNINGS=ERRORS that is
3404 -- activated by the use of /STYLE=GNAT.
3405 --
3406 -- OBSOLESCENT Activates warnings for calls to subprograms
3407 -- marked with pragma Obsolescent and for use of
3408 -- features in Annex J of the Ada Reference
3409 -- Manual. In the case of Annex J, not all
3410 -- features are flagged. In particular use of the
3411 -- renamed packages (like Text_IO), use of package
3412 -- ASCII and use of the attribute 'Constrained are
3413 -- not flagged, since these are very common and
3414 -- would generate many annoying positive warnings.
3415 -- The default is that such warnings are not
3416 -- generated.
3417 --
3418 -- NOOBSOLESCENT Disables warnings on use of obsolescent
3419 -- features.
3420 --
3421 -- OBJECT_RENAME Activate warnings for non limited objects
3422 -- renaming parameterless functions.
3423 --

3430 --
3431 -- OVERLAYS Activate warnings for possibly unintended

3433 -- clauses that cause one variable to overlap
3434 -- another. The default is that such warnings
3435 -- are generated.
3436 --
3437 -- NOOVERLAYS Suppress warnings on possibly unintended
3438 -- initialization effects of defining address
3439 -- clauses that cause one variable to overlap
3440 -- another.
3441 --
3442 -- REDUNDANT Activate warnings for redundant constructs.
3443 -- In particular assignments of a variable to
3444 -- itself, and a type conversion that converts
3445 -- an object to its own type. The default
3446 -- is that such warnings are not generated.
3447 --
3448 -- NOREDUNDANT Suppress warnings for redundant constructs.
3449 --
3450 -- SUPPRESS Completely suppress the output of all warning
3451 -- messages. Same as /NOWARNINGS.
3452 --
3453 -- UNCHECKED_CONVERSIONS Activates warnings on unchecked conversions.
3454 -- Causes warnings to be generated for
3455 -- unchecked conversions when the two types are
3456 -- known at compile time to have different sizes.
3457 -- The default is that such warnings are

3459 --
3460 -- NOUNCHECKED_CONVERSIONS Suppress warnings for unchecked conversions.
3461 --
3462 -- UNINITIALIZED Generate warnings for uninitialized variables.
3463 -- This is a GCC option, not an Ada option.
3464 -- You must also specify the /OPTIMIZE qualifier
3465 -- with a value other than NONE (in other words,
3466 -- this keyword works only if optimization is

3468 --
3469 -- UNREFERENCED_FORMALS Activate warnings on unreferenced formals.
3470 -- Causes a warning to be generated if a formal
3471 -- parameter is not referenced in the body of
3472 -- the subprogram. This warning can also be turned
3473 -- on using option ALL or UNUSED.
3474 --
3475 -- NOUNREFERENCED_FORMALS Suppress warnings on unreferenced formals.
3476 -- Suppresses warnings for unreferenced formal
3477 -- parameters. Note that the combination UNUSED
3478 -- followed by NOUNREFERENCED_FORMALS has the
3479 -- effect of warning on unreferenced entities
3480 -- other than subprogram formals.
3481 --
3482 -- UNUSED Activates warnings to be generated for entities
3483 -- that are defined but not referenced, and for
3484 -- units that are with'ed and not referenced. In
3485 -- the case of packages, a warning is also
3486 -- generated if no entities in the package are
3487 -- referenced. This means that if the package
3488 -- is referenced but the only references are in
3489 -- use clauses or renames declarations, a warning
3490 -- is still generated. A warning is also generated
3491 -- for a generic package that is with'ed but never
3492 -- instantiated. In the case where a package or
3493 -- subprogram body is compiled, and there is a
3494 -- with on the corresponding spec that is only
3495 -- referenced in the body, a warning is also
3496 -- generated, noting that the with can be moved

3507 -- warnings are generated.
3508 --
3509 -- NOVARIABLES_UNINITIALIZED
3510 -- Suppress warnings for uninitialized variables.
3511 --
3512 -- TAG_WARNINGS Causes the string [xxx] to be added to warnings
3513 -- that are controlled by the warning string xxx,
3514 -- e.g. [REDUNDANT], or if the warning is enabled
3515 -- by default, the tag is [enabled by default].
3516 --
3517 -- NOTAG_WARNINGS Turns off warning tag output (default setting).
3518 --
3519 -- WHY_SPEC_NEEDS_BODY Generates information messages showing why a
3520 -- package specification requires a body.
3521 --
3522 -- NO_WHY_SPEC_NEEDS_BODY Turns off information messages showing why a

3548 -- /NOWIDE_CHARACTER_ENCODING (D)
3549 -- /WIDE_CHARACTER_ENCODING[=encode-type]
3550 --
3551 -- Specifies the mechanism used to encode wide characters. 'encode-type'
3552 -- is one of the following:
3553 --
3554 -- BRACKETS (D) A wide character is encoded as ["xxxx"] where XXXX
3555 -- are four hexadecimal digits representing the coding
3556 -- ('Pos value) of the character in type
3557 -- Wide_Character. The hexadecimal digits may use upper
3558 -- or lower case letters.
3559 --
3560 -- This notation can also be used for upper half
3561 -- Character values using the format ["xx"] where XX is
3562 -- two hexadecimal digits representing the coding ('Pos
3563 -- value) of the character in type Character (or
3564 -- Wide_Character). The hexadecimal digits may use upper
3565 -- of lower case.
3566 --
3567 -- NONE No wide characters are allowed. Same
3568 -- as /NOWIDE_CHARACTER_ENCODING.
3569 --
3570 -- HEX In this encoding, a wide character is represented by
3571 -- the following five character sequence: ESC a b c d
3572 -- Where 'a', 'b', 'c', and 'd' are the four hexadecimal
3573 -- characters (using uppercase letters) of the wide
3574 -- character code. For example, ESC A345 is used to
3575 -- represent the wide character with code 16#A345#. This
3576 -- scheme is compatible with use of the full
3577 -- Wide_Character set.
3578 --
3579 -- UPPER The wide character with encoding 16#abcd# where the
3580 -- upper bit is on (in other words, "a" is in the range
3581 -- 8-F) is represented as two bytes, 16#ab# and 16#cd#.
3582 -- The second byte may never be a format control
3583 -- character, but is not required to be in the upper
3584 -- half. This method can be also used for shift-JIS or
3585 -- EUC, where the internal coding matches the external
3586 -- coding.
3587 --
3588 -- SHIFT_JIS A wide character is represented by a two-character
3589 -- sequence, 16#ab# and 16#cd#, with the restrictions
3590 -- described for upper-half encoding as described above.
3591 -- The internal character code is the corresponding JIS
3592 -- character according to the standard algorithm for
3593 -- Shift-JIS conversion. Only characters defined in the
3594 -- JIS code set table can be used with this encoding
3595 -- method.
3596 --
3597 -- UTF8 A wide character is represented using
3598 -- UCS Transformation Format 8 (UTF-8) as defined in Annex
3599 -- R of ISO 10646-1/Am.2. Depending on the character
3600 -- value, the representation is a one, two, or three byte
3601 -- sequence:
3602 --
3603 -- 16#0000#-16#007f#: 2#0xxxxxxx#
3604 -- 16#0080#-16#07ff#: 2#110xxxxx# 2#10xxxxxx#
3605 -- 16#0800#-16#ffff#: 2#1110xxxx# 2#10xxxxxx# 2#10xxxxxx#
3606 --
3607 -- where the xxx bits correspond to the left-padded bits
3608 -- of the 16-bit character value. Note that all lower
3609 -- half ASCII characters are represented as ASCII bytes
3610 -- and all upper half characters and other wide characters
3611 -- are represented as sequences of upper-half (The full
3612 -- UTF-8 scheme allows for encoding 31-bit characters as
3613 -- 6-byte sequences, but in this implementation, all UTF-8
3614 -- sequences of four or more bytes length will be treated
3615 -- as illegal).
3616 --
3617 -- EUC A wide character is represented by a two-character
3618 -- sequence 16#ab# and 16#cd#, with both characters being
3619 -- in the upper half. The internal character code is the
3620 -- corresponding JIS character according to the EUC
3621 -- encoding algorithm. Only characters defined in the JIS
3622 -- code set table can be used with this encoding method.
3626 -- NODOC (see /WIDE_CHARACTER_ENCODING)

3631 -- /XDEBUG
3632 --
3633 -- Output expanded source files for source level debugging.
3634 -- The expanded source (see /EXPAND_SOURCE) is written to files

7445 -- directories. The order in which library files are searched is the same
7446 -- as for MAKE.
7450 -- /PROJECT=file
7451 --
7452 -- Specify a project file to use. By default, FIND and XREF will try to
7453 -- locate a project file in the current directory.
7454 --
7455 -- If a project file is either specified or found by the tools, then the
7456 -- content of the source directory and object directory lines are added
7457 -- as if they had been specified respectively by /SOURCE_SEARCH and
7458 -- /OBJECT_SEARCH.
7462 -- /PROJECT_FILE=filename
7463 --
7464 -- Specifies the main project file to be used. The project files rooted
7465 -- at the main project file will be parsed before doing any processing.
7466 -- The source and object directories to be searched will be communicated
7467 -- to gnatxref through logical names ADA_PRJ_INCLUDE_FILE and
7468 -- ADA_PRJ_OBJECTS_FILE.
7472 -- /SEARCH=(directory,...)
7473 --
7474 -- Equivalent to:
7475 -- /OBJECT_SEARCH=(directory,...) /SOURCE_SEARCH=(directory,...)
7479 -- /SOURCE_SEARCH=(directory,...)
7480 --
7481 -- When looking for source files also look in the specified directories.
7482 -- The order in which source file search is undertaken is the same as for
7483 -- MAKE.
7487 -- /SUBDIRS=dir
7488 --
7489 -- The actual directories (object, exec, library, ...) are subdirectories
7490 -- of the directory specified in the project file. If the subdirectory
7491 -- does not exist, it is created automatically.
7495 -- /SOURCE_SEARCH=(directory,...)
7496 --
7497 -- When looking for source files also look in the specified directories.
7498 -- The order in which source file search is undertaken is the same as for
7499 -- MAKE.
7503 -- /NOTAGS (D)
7504 -- /TAGS
7505 --
7506 -- Print a 'tags' file for vi.
