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 -- Although GNAT is primarily an Ada 95 compiler, it accepts this
1218 -- qualifier to specify that an Ada 83 mode program is being compiled. If
1219 -- you specify this qualifier, GNAT rejects Ada 95 extensions and applies

1224 -- purposes, using this qualifier should ensure that programs that
1225 -- compile correctly under the /83 qualifier can be ported reasonably
1226 -- easily to an Ada 83 compiler. This is the main use of this qualifier.
1227 --
1228 -- With few exceptions (most notably the need to use "<>" on
1229 -- unconstrained generic formal parameters), it is not necessary to use
1230 -- this qualifier switch when compiling Ada 83 programs, because, with
1231 -- rare and obscure exceptions, Ada 95 is upwardly compatible with Ada

1313 -- /NOCHECKS
1314 -- /CHECKS[=(keyword[,...])]
1315 --
1316 -- If you compile with the default options, GNAT will insert many runtime
1317 -- checks into the compiled code, including code that performs range
1318 -- checking against constraints, but not arithmetic overflow checking for
1319 -- integer operations (including division by zero) or checks for access
1320 -- before elaboration on subprogram calls. All other runtime checks, as
1321 -- required by the Ada 95 Reference Manual, are generated by default.
1322 --
1323 -- You may specify one or more of the following keywords to the /CHECKS
1324 -- qualifier to modify this behavior:
1325 --
1326 -- DEFAULT The behavior described above. This is the default
1327 -- if the /CHECKS qualifier is not present on the
1328 -- command line. Same as /NOCHECKS.
1329 --
1330 -- OVERFLOW Enables overflow checking for integer operations and
1331 -- checks for access before elaboration on subprogram
1332 -- calls. This causes GNAT to generate slower and larger
1333 -- executable programs by adding code to check for both
1334 -- overflow and division by zero (resulting in raising
1335 -- "Constraint_Error" as required by Ada semantics).
1336 -- Similarly, GNAT does not generate elaboration check
1337 -- by default, and you must specify this keyword to
1338 -- enable them.
1339 --
1340 -- Note that this keyword does not affect the code
1341 -- generated for any floating-point operations; it
1342 -- applies only to integer operations. For the case of
1343 -- floating-point, GNAT has the "Machine_Overflows"
1344 -- attribute set to "False" and the normal mode of
1345 -- operation is to generate IEEE NaN and infinite values
1346 -- on overflow or invalid operations (such as dividing
1347 -- 0.0 by 0.0).
1348 --
1349 -- ELABORATION Enables dynamic checks for access-before-elaboration
1350 -- on subprogram calls and generic instantiations.
1351 --
1352 -- ASSERTIONS The pragmas "Assert" and "Debug" normally have no
1353 -- effect and are ignored. This keyword causes "Assert"
1354 -- and "Debug" pragmas to be activated, as well as
1355 -- "Check", "Precondition" and "Postcondition" pragmas.
1356 --
1357 -- SUPPRESS_ALL Suppress all runtime checks as though you have
1358 -- "pragma Suppress (all_checks)" in your source. Use
1359 -- this switch to improve the performance of the code at
1360 -- the expense of safety in the presence of invalid data
1361 -- or program bugs.

1363 -- UNSUPPRESS_ALL Cancels effect of previous SUPPRESS_ALL.
1364 --
1365 -- DEFAULT Suppress the effect of any option OVERFLOW or

1367 --
1368 -- FULL (D) Similar to OVERFLOW, but suppress the effect of any
1369 -- option ELABORATION or SUPPRESS_ALL.
1370 --
1371 -- These keywords only control the default setting of the checks. You
1372 -- may modify them using either "Suppress" (to remove checks) or

1384 --
1385 -- Compress debug information and external symbol name table entries.

1410 -- directory information) of the preprocessor data file to use.
1411 -- The preprocessor data file should be found in the source directories.
1412 --
1413 -- A preprocessing data file is a text file with significant lines
1414 -- indicating how should be preprocessed either a specific source or all
1415 -- sources not mentioned in other lines. A significant line is a non
1416 -- empty, non comment line. Comments are similar to Ada comments.
1417 --
1418 -- Each significant line starts with either a literal string or the
1419 -- character '*'. A literal string is the file name (without directory
1420 -- information) of the source to preprocess. A character '*' indicates the
1421 -- preprocessing for all the sources that are not specified explicitly on
1422 -- other lines. It is an error to have two lines with the same file name
1423 -- or two lines starting with the character '*'.
1424 --
1425 -- After the file name or the character '*', another optional literal
1426 -- string indicating the file name of the definition file to be used for
1427 -- preprocessing. (see 15.3 Form of Definitions File. The definition files
1428 -- are found by the compiler in one of the source directories. In some
1429 -- cases, when compiling a source in a directory other than the current
1430 -- directory, if the definition file is in the current directory, it may
1431 -- be necessary to add the current directory as a source directory through
1432 -- qualifier "/SEARCH=[]", otherwise the compiler would not find the
1433 -- definition file.
1434 --
1435 -- Then, optionally, switches similar to those of gnatprep may be found.
1436 -- Those switches are:
1437 --
1438 -- -b Causes both preprocessor lines and the lines deleted by
1439 -- preprocessing to be replaced by blank lines, preserving
1440 -- the line number. This switch is always implied;
1441 -- however, if specified after `-c' it cancels the effect
1442 -- of `-c'.
1443 --
1444 -- -c Causes both preprocessor lines and the lines deleted by
1445 -- preprocessing to be retained as comments marked with
1446 -- the special string "--! ".
1447 --
1448 -- -Dsymbol=value Define or redefine a symbol, associated with value.
1449 -- A symbol is an Ada identifier, or an Ada reserved word,
1450 -- with the exception of "if", "else", "elsif", "end",
1451 -- "and", "or" and "then". value is either a literal
1452 -- string, an Ada identifier or any Ada reserved word.
1453 -- A symbol declared with this switch replaces a symbol
1454 -- with the same name defined in a definition file.
1455 --
1456 -- -s Causes a sorted list of symbol names and values to be
1457 -- listed on the standard output file.
1458 --
1459 -- -u Causes undefined symbols to be treated as having the
1460 -- value FALSE in the context of a preprocessor test.
1461 -- In the absence of this option, an undefined symbol
1462 -- in a #if or #elsif test will be treated as an error.
1463 --
1464 -- Examples of valid lines in a preprocessor data file:
1465 --
1466 -- "toto.adb" "prep.def" -u
1467 -- -- preprocess "toto.adb", using definition file "prep.def",
1468 -- -- undefined symbol are False.
1469 --
1470 -- * -c -DVERSION=V101
1471 -- -- preprocess all other sources without a definition file;
1472 -- -- suppressed lined are commented; symbol VERSION has the value
1473 -- -- V101.
1474 --
1475 -- "titi.adb" "prep2.def" -s
1476 -- -- preprocess "titi.adb", using definition file "prep2.def";
1477 -- -- list all symbols with their values.
1492 -- /DEBUG[=debug-level]
1493 -- /NODEBUG
1494 --
1495 -- Specifies how much debugging information is to be included in
1496 -- the resulting object fie.
1497 --
1498 -- 'debug-level' is one of the following:
1499 --

1604 -- Follow links when parsing project files
1608 -- /NOFORCE_ALI (D)
1609 -- /FORCE_ALI
1610 --
1611 -- In normal operation mode, the .ALI file is not generated if any
1612 -- illegalities are detected in the program. The use of this qualifier
1613 -- forces generation of the .ALI file. This file is marked as being

1694 -- half (character codes 16#00# ... 16#7F#) is identical
1695 -- to standard ASCII coding, but the upper half is used
1696 -- to represent additional characters. This includes
1697 -- extended letters used by European languages, such as
1698 -- the umlaut used in German.
1699 --
1700 -- You may use any of these extended characters freely
1701 -- in character or string literals. In addition, the
1702 -- extended characters that represent letters can be
1703 -- used in identifiers.
1704 --

1709 -- and lower case equivalence.
1710 --
1711 -- 4 Latin-4 letters allowed in identifiers, with uppercase
1712 -- and lower case equivalence.
1713 --
1714 -- PC IBM PC code page 437. This code page is the normal
1715 -- default for PCs in the U.S. It corresponds to the
1716 -- original IBM PC character set. This set has some, but
1717 -- not all, of the extended Latin-1 letters, but these
1718 -- letters do not have the same encoding as Latin-1. In
1719 -- this mode, these letters are allowed in identifiers
1720 -- with uppercase and lowercase equivalence.
1721 --
1722 -- PC850 This code page (850) is a modification of 437 extended
1723 -- to include all the Latin-1 letters, but still not with
1724 -- the usual Latin-1 encoding. In this mode, all these
1725 -- letters are allowed in identifiers with uppercase and
1726 -- lower case equivalence.
1727 --
1728 -- FULL_UPPER Any character in the range 80-FF allowed in
1729 -- identifiers, and all are considered distinct. In

1731 -- equivalences in this range.
1732 --

1756 -- /NOIMMEDIATE_ERRORS (D)
1757 -- /IMMEDIATE_ERRORS
1758 --

1771 -- /NOINLINE (D)
1772 -- /INLINE[=keyword]
1773 --
1774 -- Selects the level of inlining for your program. In the absence of this
1775 -- qualifier, GNAT does not attempt inlining across units and does not
1776 -- need to access the bodies of subprograms for which "pragma Inline" is
1777 -- specified if they are not in the current unit.
1778 --
1779 -- The supported keywords are as follows:
1780 --
1781 -- PRAGMA (D) Recognize and process "Inline" pragmas. However,
1782 -- for the inlining to actually occur, optimization
1783 -- must be enabled. This enables inlining across unit
1784 -- boundaries, that is, inlining a call in one unit of
1785 -- a subprogram declared in a with'ed unit. The compiler
1786 -- will access these bodies, creating an extra source
1787 -- dependency for the resulting object file, and where
1788 -- possible, the call will be inlined.
1789 --
1790 -- This qualifier also turns on full optimization and
1791 -- requests GNAT to try to attempt automatic inlining
1792 -- of small subprograms within a unit.
1793 --
1794 -- Specifying /OPTIMIZE=NONE will disable the main effect
1795 -- of this qualifier, but you may specify other
1796 -- optimization options, to get either lower
1797 -- (/OPTIMIZE=SOME) or higher (/OPTIMIZE=UNROLL_LOOPS)
1798 -- levels of optimization.
1799 --
1800 -- FULL Front end inlining. The front end inlining activated
1801 -- by this switch is generally more extensive, and quite
1802 -- often more effective than the standard PRAGMA inlining
1803 -- mode. It will also generate additional dependencies.
1804 --
1805 -- SUPPRESS Suppresses all inlining, even if other optimization
1806 -- or inlining switches are set.
1810 -- NODOC (see /INLINE)

1858 -- /NOMACHINE_CODE_LISTING (D)
1859 -- /MACHINE_CODE_LISTING
1860 --
1861 -- Cause a full machine code listing of the file to be generated to

1863 -- qualifier is also present.
1867 -- /MAPPING_FILE=file_name
1868 --
1869 -- Use mapping file file_name
1870 --
1871 -- A mapping file is a way to communicate to the compiler two mappings:
1872 -- from unit names to file names (without any directory information) and
1873 -- from file names to path names (with full directory information).
1874 -- These mappings are used by the compiler to short-circuit the path
1875 -- search.
1876 --
1877 -- The use of mapping files is not required for correct operation of the
1878 -- compiler, but mapping files can improve efficiency, particularly when
1879 -- sources are read over a slow network connection. In normal operation,
1880 -- you need not be concerned with the format or use of mapping files,
1881 -- and /MAPPING_FILE is not a qualifier that you would use explicitly.
1882 -- It is intended only for use by automatic tools such as GNAT MAKE
1883 -- running under the project file facility. The description here of the
1884 -- format of mapping files is provided for completeness and for possible
1885 -- use by other tools.
1886 --
1887 -- A mapping file is a sequence of sets of three lines. In each set, the
1888 -- first line is the unit name, in lower case, with "%s" appended for
1889 -- specifications and "%b" appended for bodies; the second line is the
1890 -- file name; and the third line is the path name.
1891 --
1892 -- Example:
1893 --
1894 -- main%b
1895 -- main.2_ada
1896 -- /gnat/project1/sources/main.2_ada
1897 --
1898 -- When qualifier ?MAPPING_FILE is specified, the compiler will create in
1899 -- memory the two mappings from the specified file. If there is any
1900 -- problem (non existent file, truncated file or duplicate entries),
1901 -- no mapping will be created.
1902 --
1903 -- Several /MAPPING_FILE qualifiers may be specified; however, only the
1904 -- last one on the command line will be taken into account.
1905 --
1906 -- When using a project file, GNAT MAKE creates a temporary mapping file
1907 -- and communicates it to the compiler using this switch.
1916 -- /MESSAGES_PROJECT_FILE[=messages-option]
1917 --
1918 -- Specifies the "verbosity" of the parsing of project files.
1919 -- messages-option may be one of the following:
1920 --
1921 -- DEFAULT (D) No messages are output if there is no error or warning.
1922 --
1923 -- MEDIUM A small number of messages are output.
1924 --
1925 -- HIGH A great number of messages are output, most of them not
1926 -- being useful for the user.
1930 -- /MAX_NESTING=nnn
1931 --
1932 -- Set maximum level of nesting of constructs (including subprograms,
1933 -- loops, blocks, packages, and conditionals).
1934 -- The level of nesting must not exceed the given value nnn.
1935 -- A value of zero disable this style check (not enabled by default).
1939 -- /NO_GNAT_ADC
1940 --
1941 -- Cause the compiler to ignore any configuration pragmas file GNAT.ADC
1942 -- in the default directory. Implied by qualifier /PROJECT_FILE.
1943 -- Often used in conjunction with qualifier /CONFIGURATION_PRAGMAS_FILE.
1947 -- /NOLOAD
1948 --
1949 -- Cause the compiler to operate in semantic check mode with full
1950 -- checking for all illegalities specified in the reference manual, but
1951 -- without generation of any source code (no object or ALI file
1952 -- generated).
1953 --
1954 -- Since dependent files must be accessed, you must follow the GNAT
1955 -- semantic restrictions on file structuring to operate in this mode:
1956 --
1957 -- o The needed source files must be accessible.
1958 -- o Each file must contain only one compilation unit.
1959 -- o The file name and unit name must match.
1960 --
1961 -- The output consists of error messages as appropriate. No object file
1962 -- or ALI file is generated. The checking corresponds exactly to the
1963 -- notion of legality in the Ada reference manual.
1964 --
1965 -- Any unit can be compiled in semantics-checking-only mode, including
1966 -- units that would not normally be compiled (generic library units,
1967 -- subunits, and specifications where a separate body is present).
1971 -- /NOSTD_INCLUDES
1972 --
1973 -- Do not look in the default directory for source files of the runtime.
1977 -- /NOSTD_LIBRARIES
1978 --
1979 -- Do not look for library files in the system default directory.
1983 -- /NOWARNING_PRAGMAS
1984 --
1985 -- Causes all Warnings pragmas to be ignored. Useful to check if the
1986 -- program has obsolete warnings pragmas that are hiding problems.
2005 -- /NOOPTIMIZE (D)
2006 -- /OPTIMIZE[=(keyword[,...])]
2007 --
2008 -- Selects the level of optimization for your program. The supported
2009 -- keywords are as follows:
2010 --
2011 -- ALL (D) Perform most optimizations, including those that
2012 -- may be expensive.
2013 --
2014 -- NONE Do not do any optimizations. Same as /NOOPTIMIZE.
2015 --
2016 -- SOME Perform some optimizations, but omit ones that
2017 -- are costly in compilation time.
2018 --
2019 -- SPACE Optimize space usage
2020 --
2021 -- DEVELOPMENT Same as SOME.
2022 --
2023 -- INLINING Full optimization, and also attempt automatic inlining
2024 -- of small subprograms within a unit
2025 --
2026 -- UNROLL_LOOPS Try to unroll loops. This keyword may be specified
2027 -- with any keyword above other than NONE. Loop
2028 -- unrolling usually, but not always, improves the
2029 -- performance of programs.
2030 --
2031 -- NO_STRICT_ALIASING
2032 -- Suppress aliasing analysis. When optimization is
2033 -- enabled (ALL or SOME above), the compiler assumes
2034 -- that pointers do in fact point to legitimate values
2035 -- of the pointer type (allocated from the proper pool).
2036 -- If this assumption is violated, e.g. by the use of
2037 -- unchecked conversion, then it may be necessary to
2038 -- suppress this assumption using this keyword (which
2039 -- may be specified only in conjunction with any
2040 -- keyword above, other than NONE).
2044 -- NODOC (see /OPTIMIZE)
2048 -- /OUTPUT_FILE=fname
2049 --
2050 -- This has the same effect as /LIST except that the output is written
2051 -- to a file instead of to standard output. If the given fname
2052 -- does not start with a period, then it is the full name of the file
2053 -- to be written. If fname starts with a period, the name of the file
2054 -- is the concatenation of to the name of the file being compiled with
2055 -- fname where the period is replace by an underline. For example, if
2056 -- file xyz.adb is compiled with -gnatl=.lst, then the output is written
2057 -- to file xyz.adb_lst.
2068 -- /POINTER_SIZE=64 (D)
2069 -- /POINTER_SIZE[=(keyword[,...])]
2070 --
2071 -- Change how pointers and descriptors are allocated. The following

2076 -- Convention_C and generate 64bit descriptors for
2077 -- Descriptor mechanisms for calling imported
2078 -- subprograms and accept both 64bit and 32bit
2079 -- descriptors for calls to exported subprograms.
2080 --
2081 -- LONG Equivalent to option 64.
2082 --
2083 -- 32 Allocate all heap pointers in 32bit space and
2084 -- generate 32bit descriptors for Descriptor
2085 -- mechanisms for calling imported subprograms.
2086 --
2087 -- SHORT Equivalent to option 32.
2091 -- /NOPOLLING (D)
2092 -- /POLLING
2093 --
2094 -- Enable polling. See the description of pragma Polling in the GNAT
2095 -- Reference Manual for full details.
2099 -- /PROJECT_FILE=filename
2100 --
2101 -- Specifies the main project file to be used. The project files rooted
2102 -- at the main project file will be parsed before the invocation of the
2103 -- compiler. The source and object directories to be searched will be
2104 -- communicated to the compiler through logical names
2105 -- ADA_PRJ_INCLUDE_FILE and ADA_PRJ_OBJECTS_FILE.
2109 -- /PRINT_STANDARD
2110 --
2111 -- cause the compiler to output a representation of package Standard
2112 -- in a form very close to standard Ada. It is not quite possible to
2113 -- do this and remain entirely Standard (since new numeric base types
2114 -- cannot be created in standard Ada), but the output is easily
2115 -- readable to any Ada programmer, and is useful to determine the
2116 -- characteristics of target dependent types in package Standard.
2121 -- /NO_TREAT_RESTRICTIONS_AS_WARNINGS (D)
2122 -- /TREAT_RESTRICTIONS_AS_WARNINGS
2123 --
2124 -- Causes all restrictions to be treated as warnings (pragma Restriction

2147 --
2148 -- BRIEF Generate the brief format error messages to
2149 -- SYS$OUTPUT as well as the verbose format message or
2150 -- full listing.
2151 --
2152 -- FULL Normally, the compiler suppresses error messages that
2153 -- are likely to be redundant. This keyword causes all
2154 -- error messages to be generated. One particular effect
2155 -- is for the case of references to undefined variables.
2156 -- If a given variable is referenced several times, the
2157 -- normal format of messages produces one error. With
2158 -- FULL, each undefined reference produces a separate
2159 -- error message.
2160 --
2161 -- IMMEDIATE Normally, the compiler saves up error messages and
2162 -- generates them at the end of compilation in proper
2163 -- sequence. This keyword causes error messages to be
2164 -- generated as soon as they are detected. The use of
2165 -- IMMEDIATE usually causes error messages to be
2166 -- generated out of sequence. Use it when the compiler
2167 -- blows up due to an internal error. In this case, the
2168 -- error messages may be lost. Sometimes blowups are
2169 -- the result of mishandled error messages, so you may

2415 -- for multi-dimensional arrays.
2416 --
2417 -- BLANKS Blanks not allowed at statement end.
2418 -- Trailing blanks are not allowed at the end of
2419 -- statements. The purpose of this rule, together
2420 -- with option HTABS (no horizontal tabs), is to
2421 -- enforce a canonical format for the use of
2422 -- blanks to separate source tokens.
2423 --
2424 -- COMMENTS Check comments.
2425 -- Comments must meet the following set of rules:
2426 --
2427 -- * The "--" that starts the column must either
2428 -- start in column one, or else at least one
2429 -- blank must precede this sequence.
2430 --
2431 -- * Comments that follow other tokens on a line
2432 -- must have at least one blank following the
2433 -- "--" at the start of the comment.
2434 --
2435 -- * Full line comments must have two blanks
2436 -- following the "--" that starts the comment,
2437 -- with the following exceptions.
2438 --
2439 -- * A line consisting only of the "--"
2440 -- characters, possibly preceded by blanks is
2441 -- permitted.
2442 --
2443 -- * A comment starting with "--x" where x is
2444 -- a special character is permitted. This
2445 -- allows proper processing of the output
2446 -- generated by specialized tools including
2447 -- gnatprep (where --! is used) and the SPARK
2448 -- annotation language (where --# is used).
2449 -- For the purposes of this rule, a special
2450 -- character is defined as being in one of the
2451 -- ASCII ranges 16#21#..16#2F# or
2452 -- 16#3A#..16#3F#.
2453 --
2454 -- * A line consisting entirely of minus signs,
2455 -- possibly preceded by blanks, is permitted.
2456 -- This allows the construction of box
2457 -- comments where lines of minus signs are
2458 -- used to form the top and bottom of the box.
2459 --
2460 -- * If a comment starts and ends with "--" is
2461 -- permitted as long as at least one blank
2462 -- follows the initial "--". Together with
2463 -- the preceding rule, this allows the
2464 -- construction of box comments, as shown in
2465 -- the following example:
2466 --
2467 -- ---------------------------
2468 -- -- This is a box comment --
2469 -- ---------------------------
2470 --
2471 -- DOS_LINE_ENDINGS Check that no DOS line terminators are present
2472 -- All lines must be terminated by a single
2473 -- ASCII.LF character. In particular the DOS line
2474 -- terminator sequence CR / LF is not allowed).
2475 --
2476 -- END Check end/exit labels.
2477 -- Optional labels on end statements ending
2478 -- subprograms and on exit statements exiting
2479 -- named loops, are required to be present.
2480 --
2481 -- GNAT Enforces a set of style conventions that
2482 -- match the style used in the GNAT source code.
2483 -- This maybe useful when developing code that
2484 -- is eventually intended to be incorporated into
2485 -- GNAT. For further details, see GNAT sources.
2486 --
2487 -- HTABS No horizontal tabs.
2488 -- Horizontal tab characters are not permitted in
2489 -- the source text. Together with the BLANKS
2490 -- (no blanks at end of line) option, this
2491 -- enforces a canonical form for the use of blanks
2492 -- to separate source tokens.
2493 --
2494 -- IF_THEN Check if-then layout.
2495 -- The keyword then must appear either on the
2496 -- same line as the corresponding if, or on a line
2497 -- on its own, lined up under the if with at least
2498 -- one non-blank line in between containing all or
2499 -- part of the condition to be tested.
2500 --
2501 -- KEYWORD Check keyword casing.
2502 -- All keywords must be in lower case (with the
2503 -- exception of keywords such as digits used as
2504 -- attribute names to which this check does not
2505 -- apply).
2506 --
2507 -- LAYOUT Check layout.
2508 -- Layout of statement and declaration constructs
2509 -- must follow the recommendations in the Ada
2510 -- Reference Manual, as indicated by the form of
2511 -- the syntax rules. For example an else keyword
2512 -- must be lined up with the corresponding if
2513 -- keyword.
2514 --
2515 -- There are two respects in which the style rule
2516 -- enforced by this check option are more liberal
2517 -- than those in the Ada Reference Manual.
2518 -- First in the case of record declarations,
2519 -- it is permissible to put the record keyword on
2520 -- the same line as the type keyword, and then
2521 -- the end in end record must line up under type.
2522 -- For example, either of the following two
2523 -- layouts is acceptable:
2524 --
2525 -- type q is record
2526 -- a : integer;
2527 -- b : integer;
2528 -- end record;
2529 --
2530 -- type q is
2531 -- record
2532 -- a : integer;
2533 -- b : integer;
2534 -- end record;
2535 --
2536 -- Second, in the case of a block statement,
2537 -- a permitted alternative is to put the block
2538 -- label on the same line as the declare or begin
2539 -- keyword, and then line the end keyword up under
2540 -- the block label. For example both the following
2541 -- are permitted:
2542 --
2543 --
2544 --
2545 -- Block : declare
2546 -- A : Integer := 3;
2547 -- begin
2548 -- Proc (A, A);
2549 -- end Block;
2550 --
2551 -- Block :
2552 -- declare
2553 -- A : Integer := 3;
2554 -- begin
2555 -- Proc (A, A);
2556 -- end Block;
2557 --
2558 -- The same alternative format is allowed for
2559 -- loops. For example, both of the following are
2560 -- permitted:
2561 --
2562 --
2563 --
2564 -- Clear : while J < 10 loop
2565 -- A (J) := 0;
2566 -- end loop Clear;
2567 --
2568 -- Clear :
2569 -- while J < 10 loop
2570 -- A (J) := 0;
2571 -- end loop Clear;
2572 --
2573 --
2574 --
2575 -- LINE_LENGTH Check maximum line length.
2576 -- The length of source lines must not exceed 79
2577 -- characters, including any trailing blanks
2578 -- The value of 79 allows convenient display on
2579 -- an 80 character wide device or window, allowing
2580 -- for possible special treatment of 80 character
2581 -- lines.
2582 --
2583 -- NONE Clear any previously set style checks.
2584 --
2585 -- ORDERED_SUBPROGRAMS Check order of subprogram bodies.
2586 -- All subprogram bodies in a given scope (e.g.
2587 -- a package body) must be in alphabetical order.
2588 -- The ordering rule uses normal Ada rules for
2589 -- comparing strings, ignoring casing of letters,
2590 -- except that if there is a trailing numeric
2591 -- suffix, then the value of this suffix is used
2592 -- in the ordering (e.g. Junk2 comes before
2593 -- Junk10).
2594 --
2595 -- OVERRIDING_INDICATORS Check that overriding subprograms are
2596 -- explicitly marked as such. The declaration of
2597 -- a primitive operation of a type extension that
2598 -- overrides an inherited operation must carry
2599 -- an overriding indicator.
2600 --
2601 -- PRAGMA Check pragma casing.
2602 -- Pragma names must be written in mixed case,
2603 -- that is, the initial letter and any letter
2604 -- following an underscore must be uppercase.
2605 -- All other letters must be lowercase.
2606 --
2607 -- REFERENCES Check references.
2608 -- All identifier references must be cased in the
2609 -- same way as the corresponding declaration.
2610 -- No specific casing style is imposed on
2611 -- identifiers. The only requirement is for
2612 -- consistency of references with declarations.
2613 --
2614 -- SPECS Check separate specs.
2615 -- Separate declarations ("specs") are required
2616 -- for subprograms (a body is not allowed to serve
2617 -- as its own declaration). The only exception is
2618 -- that parameterless library level procedures are
2619 -- not required to have a separate declaration.
2620 -- This exception covers the most frequent form of
2621 -- main program procedures.
2622 --
2623 -- STANDARD_CASING Check casing of entities in Standard.
2624 -- Any identifier from Standard must be cased to
2625 -- match the presentation in the Ada Reference
2626 -- Manual (for example, Integer and ASCII.NUL).
2627 --
2628 -- TOKEN Check token spacing.
2629 -- The following token spacing rules are enforced:
2630 --
2631 -- * The keywords abs and not must be followed
2632 -- by a space.
2633 --
2634 -- * The token => must be surrounded by spaces.
2635 --
2636 -- * The token <> must be preceded by a space or
2637 -- a left parenthesis.
2638 --
2639 -- * Binary operators other than ** must be
2640 -- surrounded by spaces. There is no
2641 -- restriction on the layout of the ** binary
2642 -- operator.
2643 --
2644 -- * Colon must be surrounded by spaces.
2645 --
2646 -- * Colon-equal (assignment) must be surrounded
2647 -- by spaces.
2648 --
2649 -- * Comma must be the first non-blank character
2650 -- on the line, or be immediately preceded by
2651 -- a non-blank character, and must be followed
2652 -- by a space.
2653 --
2654 -- * If the token preceding a left paren ends
2655 -- with a letter or digit, then a space must
2656 -- separate the two tokens.
2657 --
2658 -- * A right parenthesis must either be the
2659 -- first non-blank character on a line, or it
2660 -- must be preceded by a non-blank character.
2661 --
2662 -- * A semicolon must not be preceded by
2663 -- a space, and must not be followed by
2664 -- a non-blank character.
2665 --
2666 -- * A unary plus or minus may not be followed
2667 -- by a space.
2668 --
2669 -- * A vertical bar must be surrounded by
2670 -- spaces.
2671 --
2672 -- In the above rules, appearing in column one is
2673 -- always permitted, that is, counts as meeting
2674 -- either a requirement for a required preceding
2675 -- space, or as meeting a requirement for no
2676 -- preceding space.
2677 --
2678 -- Appearing at the end of a line is also always
2679 -- permitted, that is, counts as meeting either
2680 -- a requirement for a following space,
2681 -- or as meeting a requirement for no following
2682 -- space.
2683 --
2684 -- UNNECESSARY_BLANK_LINES
2685 -- Check for unnecessary blank lines.
2686 -- A blank line is considered unnecessary if it
2687 -- appears at the end of the file, or if more
2688 -- than one blank line occurs in sequence.
2689 --
2690 -- VTABS No form feeds or vertical tabs.
2691 -- Form feeds or vertical tab characters are not
2692 -- permitted in the source text.
2693 --
2694 -- XTRA_PARENS Check for the use of an unnecessary extra
2695 -- level of parentheses (C - style) around
2696 -- conditions in if statements, while statements
2697 -- and exit statements.
2701 -- NODOC (see /STYLE_CHECKS)
2705 -- /SUBDIRS=dir
2706 --
2707 -- The actual directories (object, exec, library, ...) are subdirectories
2708 -- of the directory specified in the project file. If the subdirectory
2709 -- does not exist, it is created automatically.
2713 -- /SYMBOL_PREPROCESSING="symbol=value"
2714 --
2715 -- Define or redefine a preprocessing symbol, associated with value.
2716 -- If "=value" is not specified, then the value of the symbol is True.
2717 -- A symbol is an identifier, following normal Ada (case-insensitive)
2718 -- rules for its syntax, and value is any sequence (including an empty
2719 -- sequence) of characters from the set (letters, digits, period,
2720 -- underline). Ada reserved words may be used as symbols, with the
2721 -- exceptions of "if", "else", "elsif", "end", "and", "or" and "then".
2722 --
2723 -- A symbol declared with this qualifier on the command line replaces
2724 -- a symbol with the same name either in a definition file or specified
2725 -- with a switch -D in the preprocessor data file.
2726 --
2727 -- This qualifier is similar to qualifier /ASSOCIATE of
2728 -- GNAT PREPROCESSING.
2732 -- /NOSYNTAX_ONLY (D)
2733 -- /SYNTAX_ONLY
2734 --
2735 -- Run GNAT in syntax checking only mode. You can check a series of
2736 -- files in a single command, and can use wild cards to specify such a
2737 -- group of files.
2738 --
2739 -- You may use other qualifiers in conjunction with this qualifier. In
2740 -- particular, /LIST and /REPORT_ERRORS=VERBOSE are useful to control the
2741 -- format of any generated error messages.
2742 --
2743 -- The output is simply the error messages, if any. No object file or ALI
2744 -- file is generated by a syntax-only compilation. Also, no units other
2745 -- than the one specified are accessed. For example, if a unit "X" with's
2746 -- a unit "Y", compiling unit "X" in syntax check only mode does not
2747 -- access the source file containing unit "Y".
2748 --
2749 -- Normally, GNAT allows only a single unit in a source file. However,
2750 -- this restriction does not apply in syntax-check-only mode, and it is
2751 -- possible to check a file containing multiple compilation units
2752 -- concatenated together. This is primarily used by the GNAT CHOP
2753 -- command.
2757 -- /TABLE_MULTIPLIER=nnn
2758 --
2759 -- All compiler tables start at nnn times usual starting size.
2763 -- /TRACE_UNITS
2764 -- /NOTRACE_UNITS
2765 --
2766 -- This switch that does for the frontend what /VERBOSE does for the
2767 -- backend. The system prints the name of each unit, either a compilation
2768 -- unit or nested unit, as it is being analyzed.
2772 -- /TREE_OUTPUT
2773 -- /NOTREE_OUTPUT
2774 --
2775 -- Cause GNAT to write the internal tree for a unit to a file (with the
2776 -- filetype ATB for a body or ATS for a spec). This is not normally
2777 -- required, but is used by separate analysis tools. Typically these
2778 -- tools do the necessary compilations automatically, so you should never
2779 -- have to specify this switch in normal operation.
2783 -- /TRY_SEMANTICS
2784 -- /NOTRY_SEMANTICS
2785 --
2786 -- In normal operation mode the compiler first parses the program and
2787 -- determines if there are any syntax errors. If there are, appropriate
2788 -- error messages are generated and compilation is immediately
2789 -- terminated. This qualifier tells GNAT to continue with semantic
2790 -- analysis even if syntax errors have been found. This may enable the
2791 -- detection of more errors in a single run. On the other hand, the
2792 -- semantic analyzer is more likely to encounter some internal fatal
2793 -- error when given a syntactically invalid tree.
2797 -- /NOUNCHECKED_SHARED_LIB_IMPORTS (D)
2798 -- /UNCHECKED_SHARED_LIB_IMPORTS
2799 --

2809 -- either directly or indirectly.
2813 -- /NOUNIQUE_ERROR_TAG (D)

2875 -- /VALIDITY_CHECKING[=(keyword,[...])]
2876 --
2877 -- Control level of validity checking.
2878 --
2879 -- DEFAULT (D) In this mode checks are made to prevent
2880 -- erroneous behavior in accordance with the RM.
2881 -- Notably extra checks may be needed for case
2882 -- statements and subscripted array assignments.
2883 --
2884 -- NONE No special checks for invalid values are
2885 -- performed. This means that references to
2886 -- uninitialized variables can cause erroneous
2887 -- behavior from constructs like case statements
2888 -- and subscripted array assignments. In this
2889 -- mode, invalid values can lead to erroneous
2890 -- behavior.
2891 --
2892 -- FULL Every assignment is checked for validity, so
2893 -- that it is impossible to assign invalid values.
2894 -- The RM specifically allows such assignments,
2895 -- but in this mode, invalid values can never be
2896 -- assigned, and an attempt to perform such an
2897 -- assignment immediately raises Constraint_Error.
2898 -- This behavior is allowed (but not required) by
2899 -- the RM. This mode is intended as a debugging aid,
2900 -- and may be useful in helping to track down
2901 -- uninitialized variables. It may be useful to
2902 -- use this in conjunction with the Normalize_Scalars
2903 -- pragma which attempts to initialize with invalid
2904 -- values where possible.
2908 -- /VERBOSE
2909 -- /NOVERBOSE
2910 --

2917 -- /NOASM (D)
2918 -- /ASM
2919 --
2920 -- Use to cause the assembler source file to be generated, using S as the

3092 -- /WARNINGS[=(keyword[,...])]
3093 --
3094 -- In addition to error messages, corresponding to illegalities as

3126 -- to Ada.
3127 --
3128 -- CONDITIONALS Activate warnings for conditional

3130 -- to be True or False at compile time. The
3131 -- default is that such warnings are not
3132 -- generated.
3133 --

3135 -- expressions used in tests that are known
3136 -- to be True or False at compile time.
3137 --
3138 -- IMPLICIT_DEREFERENCE Activate warnings on implicit dereferencing.
3139 -- The use of a prefix of an access type in an

3191 -- Activates warnings for failure of front end
3192 -- inlining (activated by /INLINE=FULL) to inline

3198 --
3199 -- NOINEFFECTIVE_INLINE Suppress warnings on ineffective pragma Inlines
3200 -- Suppresses warnings on ineffective pragma

3384 -- /NOWIDE_CHARACTER_ENCODING (D)
3385 -- /WIDE_CHARACTER_ENCODING[=encode-type]
3386 --
3387 -- Specifies the mechanism used to encode wide characters. 'encode-type'
3388 -- is one of the following:
3389 --
3390 -- BRACKETS (D) A wide character is encoded as ["xxxx"] where XXXX
3391 -- are four hexadecimal digits representing the coding
3392 -- ('Pos value) of the character in type
3393 -- Wide_Character. The hexadecimal digits may use upper
3394 -- or lower case letters.
3395 --
3396 -- This notation can also be used for upper half
3397 -- Character values using the format ["xx"] where XX is
3398 -- two hexadecimal digits representing the coding ('Pos
3399 -- value) of the character in type Character (or
3400 -- Wide_Character). The hexadecimal digits may use upper
3401 -- of lower case.
3402 --
3403 -- NONE No wide characters are allowed. Same
3404 -- as /NOWIDE_CHARACTER_ENCODING.
3405 --
3406 -- HEX In this encoding, a wide character is represented by
3407 -- the following five character sequence: ESC a b c d
3408 -- Where 'a', 'b', 'c', and 'd' are the four hexadecimal
3409 -- characters (using uppercase letters) of the wide
3410 -- character code. For example, ESC A345 is used to
3411 -- represent the wide character with code 16#A345#. This
3412 -- scheme is compatible with use of the full
3413 -- Wide_Character set.
3414 --
3415 -- UPPER The wide character with encoding 16#abcd# where the
3416 -- upper bit is on (in other words, "a" is in the range
3417 -- 8-F) is represented as two bytes, 16#ab# and 16#cd#.
3418 -- The second byte may never be a format control
3419 -- character, but is not required to be in the upper
3420 -- half. This method can be also used for shift-JIS or
3421 -- EUC, where the internal coding matches the external
3422 -- coding.
3423 --
3424 -- SHIFT_JIS A wide character is represented by a two-character
3425 -- sequence, 16#ab# and 16#cd#, with the restrictions
3426 -- described for upper-half encoding as described above.
3427 -- The internal character code is the corresponding JIS
3428 -- character according to the standard algorithm for
3429 -- Shift-JIS conversion. Only characters defined in the
3430 -- JIS code set table can be used with this encoding
3431 -- method.
3432 --
3433 -- UTF8 A wide character is represented using
3434 -- UCS Transformation Format 8 (UTF-8) as defined in Annex
3435 -- R of ISO 10646-1/Am.2. Depending on the character
3436 -- value, the representation is a one, two, or three byte
3437 -- sequence:
3438 --
3439 -- 16#0000#-16#007f#: 2#0xxxxxxx#
3440 -- 16#0080#-16#07ff#: 2#110xxxxx# 2#10xxxxxx#
3441 -- 16#0800#-16#ffff#: 2#1110xxxx# 2#10xxxxxx# 2#10xxxxxx#
3442 --
3443 -- where the xxx bits correspond to the left-padded bits
3444 -- of the 16-bit character value. Note that all lower
3445 -- half ASCII characters are represented as ASCII bytes
3446 -- and all upper half characters and other wide characters
3447 -- are represented as sequences of upper-half (The full
3448 -- UTF-8 scheme allows for encoding 31-bit characters as
3449 -- 6-byte sequences, but in this implementation, all UTF-8
3450 -- sequences of four or more bytes length will be treated
3451 -- as illegal).
3452 --
3453 -- EUC A wide character is represented by a two-character
3454 -- sequence 16#ab# and 16#cd#, with both characters being
3455 -- in the upper half. The internal character code is the
3456 -- corresponding JIS character according to the EUC
3457 -- encoding algorithm. Only characters defined in the JIS
3458 -- code set table can be used with this encoding method.

4562 -- be used with a main subprogram on the command line or for

4662 --
4663 -- Specifies an external reference to the project manager. Useful only if
4664 -- /PROJECT_FILE is used.
4665 --
4666 -- Example:
4667 -- /EXTERNAL_REFERENCE="DEBUG=TRUE"
4671 -- /NOFOLLOW_LINKS_FOR_FILES (D)
4672 -- /FOLLOW_LINKS_FOR_FILES
4673 --
4674 -- Follow links when parsing project files
4678 -- /NOFORCE_COMPILE (D)
4679 -- /FORCE_COMPILE
4680 --
4681 -- Force recompilations. Recompile all sources, even though some object
4682 -- files may be up to date, but don't recompile predefined or GNAT
4683 -- internal files unless the /ALL_FILES qualifier is also specified.
4687 -- /NOFULL_PATH_IN_BRIEF_MESSAGES (D)
4688 -- /FULL_PATH_IN_BRIEF_MESSAGES
4689 --
4690 -- When using project files, if some errors or warnings are detected
4691 -- during parsing and verbose mode is not in effect (no use of qualifier
4692 -- /VERBOSE), then error lines start with the full path name of the
4693 -- project file, rather than its simple file name.
4697 -- /NOHIGH_VERBOSITY (D)
4698 -- /HIGH_VERBOSITY
4699 --
4700 -- Displays the reason for all recompilations GNAT MAKE decides are
4701 -- necessary, in high verbosity. Equivalent to /VERBOSE.
4705 -- /NOIN_PLACE (D)
4706 -- /IN_PLACE
4707 --
4708 -- In normal mode, GNAT MAKE compiles all object files and ALI files
4709 -- into the current directory. If the /IN_PLACE switch is used,
4710 -- then instead object files and ALI files that already exist are over-
4711 -- written in place. This means that once a large project is organized
4712 -- into separate directories in the desired manner, then GNAT MAKE will
4713 -- automatically maintain and update this organization. If no ALI files
4714 -- are found on the Ada object path, the new object and ALI files are
4715 -- created in the directory containing the source being compiled.
4719 -- /SOURCE_INDEX=nnn
4720 --
4721 -- Specifies the index of the units in the source file
4722 -- By default, source files are mono-unit and there is no index
4723 -- When /SOURCE_INDEX=nnn is specified, only one main may be specified
4724 -- on the command line.
4728 -- /LIBRARY_SEARCH=(directory[,...])
4729 --
4730 -- Add the specified directories to the list of directories in which the
4731 -- linker will search for libraries.
4735 -- /LINKER_QUALIFIERS
4736 --
4737 -- Any qualifiers specified after this qualifier other than
4738 -- /COMPILER_QUALIFIERS, /BINDER_QUALIFIERS and /MAKE_QUALIFIERS will be
4739 -- passed to any GNAT LINK commands generated by GNAT LINK.
4743 -- /NOLOW_VERBOSITY (D)
4744 -- /LOW_VERBOSITY
4745 --
4746 -- Displays the reason for all recompilations GNAT MAKE decides are
4747 -- necessary, in low verbosity, that is with less output than
4748 -- /MEDIUM_VERBOSITY, /HIGH_VERBOSITY or /VERBOSE.
4752 -- /MAKE_QUALIFIERS
4753 --
4754 -- Any qualifiers specified after this qualifier other than
4755 -- /COMPILER_QUALIFIERS, /BINDER_QUALIFIERS and /LINKER_QUALIFIERS
4756 -- are for the benefit of GNAT MAKE itself.
4760 -- /NOMAPPING (D)
4761 -- /MAPPING
4762 --
4763 -- Use a mapping file. A mapping file is a way to communicate to the
4764 -- compiler two mappings: from unit names to file names (without any
4765 -- directory information) and from file names to path names (with full
4766 -- directory information). These mappings are used by the compiler to
4767 -- short-circuit the path search. When GNAT MAKE is invoked with this
4768 -- qualifier, it will create a mapping file, initially populated by the
4769 -- project manager, if /PROJECT_File= is used, otherwise initially empty.
4770 -- Each invocation of the compiler will add the newly accessed sources to
4771 -- the mapping file. This will improve the source search during the next
4772 -- invocations of the compiler
4776 -- /NOMEDIUM_VERBOSITY (D)
4777 -- /MEDIUM_VERBOSITY
4778 --
4779 -- Displays the reason for all recompilations GNAT MAKE decides are
4780 -- necessary, in medium verbosity, that is with potentially less output
4781 -- than /HIGH_VERBOSITY or /VERBOSE.
4790 -- /MESSAGES_PROJECT_FILE[=messages-option]
4791 --
4792 -- Specifies the "verbosity" of the parsing of project files.
4793 -- messages-option may be one of the following:
4794 --
4795 -- DEFAULT (D) No messages are output if there is no error or warning.
4796 --
4797 -- MEDIUM A small number of messages are output.
4798 --
4799 -- HIGH A great number of messages are output, most of them not
4800 -- being useful for the user.
4804 -- /NOMINIMAL_RECOMPILATION (D)
4805 -- /MINIMAL_RECOMPILATION
4806 --
4807 -- Specifies that the minimum necessary amount of recompilation
4808 -- be performed. In this mode GNAT MAKE ignores time stamp differences
4809 -- when the only modifications to a source file consist in
4810 -- adding/removing comments, empty lines, spaces or tabs.
4814 -- /NOCREATE_MISSING_DIRS (D)
4815 -- /CREATE_MISSING_DIRS
4816 --
4817 -- When an object directory, a library directory or an exec directory
4818 -- in missing, attempt to create the directory.
4822 -- /NOLINK
4823 --
4824 -- Compile only. Do not perform binding and linking. If the root unit is
4825 -- not a main unit, this is the default. Otherwise GNAT MAKE will
4826 -- attempt binding and linking unless all objects are up to date and the
4827 -- executable is more recent than the objects.
4828 -- This is equivalent to /ACTIONS=COMPILE
4832 -- /NOMAIN
4833 --
4834 -- No main subprogram. Bind and link the program even if the unit name
4835 -- given on the command line is a package name. The resulting executable
4836 -- will execute the elaboration routines of the package and its closure,
4837 -- then the finalization routines.
4841 -- /NON_PROJECT_UNIT_COMPILATION
4842 --
4843 -- Normally, when using project files, a unit that is not part of any
4844 -- project file, cannot be compile. These units may be compile, when
4845 -- needed, if this qualifier is specified.
4849 -- /NOSTD_INCLUDES
4850 --
4851 -- Do not look for sources the in the system default directory.
4855 -- /NOSTD_LIBRARIES
4856 --
4857 -- Do not look for library files in the system default directory.
4861 -- /OBJECT_SEARCH=(directory[,...])
4862 --
4863 -- When looking for library and object files look also in the specified
4864 -- directories.
4868 -- /NOPROCESSES (D)
4869 -- /PROCESSES=NNN
4870 --
4871 -- Use NNN processes to carry out the (re)compilations. If you have a
4872 -- multiprocessor machine, compilations will occur in parallel. In the
4873 -- event of compilation errors, messages from various compilations might
4874 -- get interspersed (but GNAT MAKE will give you the full ordered list of
4875 -- failing compiles at the end). This can at times be annoying. To get a
4876 -- clean list of error messages don't use this qualifier.
4880 -- NODOC (see /PROCESS)
4884 -- /PROJECT_FILE=filename
4885 --
4886 -- Specifies the main project file to be used. The project files rooted
4887 -- at the main project file will be parsed before any other processing to
4888 -- set the building environment.
4892 -- /NOQUIET (D)
4893 -- /QUIET
4894 --
4895 -- When this qualifiers is specified, the commands carried out by GNAT
4896 -- MAKE are not displayed.
4900 -- /NOREASONS (D)
4901 -- /REASONS
4902 --
4903 -- Displays the reason for all recompilations GNAT MAKE decides are

4908 -- /RUNTIME_SYSTEM=xxx
4909 --
4910 -- Build against an alternate runtime system named xxx or RTS-xxx.

4936 -- When looking for source files also look in the specified directories.
4940 -- /SRC_INFO=source-info-file
4941 --
4942 -- Specify a source info file to be read or written by the Project
4943 -- Manager when project files are used.
4947 -- /NOSTANDARD_OUTPUT_FOR_COMMANDS (D)
4948 -- /STANDARD_OUTPUT_FOR_COMMANDS
4949 --
4950 -- Output the commands for the compiler, the binder and the linker
4951 -- on SYS$OUTPUT, instead of SYS$ERROR.
4955 -- /SUBDIRS=dir
4956 --
4957 -- The actual directories (object, exec, library, ...) are subdirectories
4958 -- of the directory specified in the project file. If the subdirectory
4959 -- does not exist, it is created automatically.
4963 -- /NOSWITCH_CHECK (D)
4964 -- /SWITCH_CHECK
4965 --
4966 -- Recompile if compiler switches have changed since last compilation.
4967 -- All compiler switches but -I and -o are taken into account in the
4968 -- following way: orders between different "first letter" switches are
4969 -- ignored, but orders between same switches are taken into account.
4970 -- For example, -O -O2 is different than -O2 -O, but -g -O is equivalent
4971 -- to -O -g.
4975 -- /NOUNCHECKED_SHARED_LIB_IMPORTS (D)
4976 -- /UNCHECKED_SHARED_LIB_IMPORTS
4977 --
4978 -- Allow shared library projects to import static library projects
4982 -- /NOUNIQUE (D)
4983 -- /UNIQUE
4984 --
4985 -- Recompile at most the main file. It implies /ACTIONS=COMPILE.
4986 -- Combined with /FORCE_COMPILE, it is equivalent to calling the compiler
4987 -- directly.
4991 -- /USE_MAPPING_FILE=file_name
4992 --
4993 -- Use a specific mapping file. The file 'file_name', specified as a path
4994 -- name (absolute or relative) by this qualifier, should already exist,
4995 -- otherwise the qualifier is ineffective. The specified mapping file

6685 -- Follow links when parsing project files
6689 -- /NOFULL (D)
6690 -- /FULL
6691 --
6692 -- If the destination directory already contains a file with the name of
6693 -- the body file for the argument file spec, replace it with the generated
6694 -- body stub. If /FULL is not used and there is already a body file, this
6695 -- existing body file is not replaced.
6702 -- /HEADER[=header-option]
6703 --
6704 -- Specifies the form of the comment header above the generated body stub.
6705 -- If no /HEADER qualifier is specified, there is no comment header.
6706 -- header-option is one of the following:
6707 --

6729 -- Default indentation is 3.
6733 -- /NOKEEP (D)
6734 -- /KEEP
6735 --
6736 -- Do not delete the tree file (i.e., the snapshot of the compiler
6737 -- internal structures used by gnatstub) after creating the body stub.
6741 -- /LINE_LENGTH=nnn
6742 --

6753 -- /MESSAGES_PROJECT_FILE[=messages-option]
6754 --
6755 -- Specifies the "verbosity" of the parsing of project files.
6756 -- messages-option may be one of the following:

6759 --
6760 -- MEDIUM A small number of messages are output.
6761 --
6762 -- HIGH A great number of messages are output, most of them not

6781 -- /OUTPUT=filespec
6782 --
6783 -- Body file name. This should be set if the argument file name does not
6784 -- follow the GNAT file naming conventions. If this switch is omitted,
6785 -- the default name for the body will be obtained from the argument file
6786 -- name according to the GNAT file naming conventions.
6790 -- /PROJECT_FILE=filename
6791 --
6792 -- Specifies the main project file to be used. The project files rooted
6793 -- at the main project file will be parsed before any other processing.
6794 -- The source and object directories to be searched will be communicated
6795 -- to gnatstub through logical names ADA_PRJ_INCLUDE_FILE and
6796 -- ADA_PRJ_OBJECTS_FILE.
6800 -- /NOQUIET (D)
6801 -- /QUIET
6802 --
6803 -- Quiet mode: do not generate a confirmation when a body is successfully
6804 -- created, and do not generate a message when a body is not required for
6805 -- an argument unit.
6809 -- /SEARCH=(directory[,...])
6810 --
6811 -- When looking for source files also look in directories specified.
6815 -- /SUBDIRS=dir
6816 --
6817 -- The actual directories (object, exec, library, ...) are subdirectories
6818 -- of the directory specified in the project file. If the subdirectory
6819 -- does not exist, it is created automatically.
6828 -- /TREE_FILE[=treefile-option]
6829 --
6830 -- Specify what to do with the tree file.
6831 -- treefile-option is one of the following:
6832 --
6833 -- OVERWRITE (D) Overwrite the existing tree file. If the current
6834 -- directory already contains the file which, according
6835 -- to the GNAT file naming rules should be considered
6836 -- as a tree file for the argument source file, gnatstub
6837 -- will refuse to create the tree file needed to create
6838 -- a sample body unless this option is chosen.
6839 --
6840 -- SAVE Do not remove the tree file (i.e., the snapshot
6841 -- of the compiler internal structures used by gnatstub)
6842 -- after creating the body stub.
6843 --
6844 -- REUSE Reuse the tree file (if it exists) instead of
6845 -- creating it.
6846 -- Instead of creating the tree file for the library
6847 -- unit declaration, gnatstub tries to find it in the
6848 -- current directory and use it for creating a body.
6849 -- If the tree file is not found, no body is created.
6850 -- This option also implies `SAVE', whether or not the
6851 -- latter is set explicitly.
6855 -- /NOVERBOSE (D)
6856 -- /VERBOSE
6857 --
6858 -- Verbose mode: generate version information.
