24 ------------------------------------------------------------------------------
26 -- This package contains, for each of the command of the GNAT driver, one
27 -- constant array; each component of this array is a string that defines,
28 -- in coded form as explained below, the conversion of a VMS qualifier of the
29 -- command to the corresponding switch of the GNAT tool corresponding to the
30 -- command.
32 -- This package is used by the GNAT driver to invokes the GNAT tools with the
33 -- switches corresponding to the VMS qualifier and by the Project Manager to
34 -- convert VMS qualifiers in project files to their corresponding switch
35 -- values.
37 -- This package is also an input to the tool that generates the VMS GNAT
38 -- help information automatically.
40 -- NOTE: the format of this package must follow the following rules, so that
41 -- the VMS GNAT help tool works properly:
43 -- - Each command zone (where the eventual qualifiers are declared) must
44 -- begin with a boxed comment of the form:
46 -- ---------------------------------
47 -- -- Switches for GNAT <COMMAND> --
48 -- ---------------------------------
50 -- where <COMMAND> is the name of a GNAT command in capital letters, for
51 -- example BIND, COMPILE, XREF, ...
53 -- - each qualifier declaration must be followed either by
54 -- - a comment starting with "-- NODOC", to indicate that there is
55 -- no documentation for this qualifier, or
56 -- - a contiguous sequence of comments that constitute the
57 -- documentation of the qualifier.
59 -- - each command zone ends with the declaration of the constant array
60 -- for the command, of the form:
62 -- <Command>__Switches : aliased constant Switches :=
66 ----------------
67 -- QUALIFIERS --
68 ----------------
70 -- The syntax of a qualifier declaration is as follows:
72 -- SWITCH_STRING ::= "/ command-qualifier-name TRANSLATION"
74 -- TRANSLATION ::=
75 -- DIRECT_TRANSLATION
76 -- | DIRECTORIES_TRANSLATION
77 -- | FILE_TRANSLATION
78 -- | NO_SPACE_FILE_TRANSL
79 -- | NUMERIC_TRANSLATION
80 -- | STRING_TRANSLATION
81 -- | OPTIONS_TRANSLATION
82 -- | COMMANDS_TRANSLATION
83 -- | ALPHANUMPLUS_TRANSLATION
84 -- | OTHER_TRANSLATION
86 -- DIRECT_TRANSLATION ::= space UNIX_SWITCHES
87 -- DIRECTORIES_TRANSLATION ::= =* UNIX_SWITCH *
88 -- DIRECTORY_TRANSLATION ::= =% UNIX_SWITCH %
89 -- FILE_TRANSLATION ::= =@ UNIX_SWITCH @
90 -- NO_SPACE_FILE_TRANSL ::= =< UNIX_SWITCH >
91 -- NUMERIC_TRANSLATION ::= =# UNIX_SWITCH # | # number #
92 -- STRING_TRANSLATION ::= =" UNIX_SWITCH "
93 -- OPTIONS_TRANSLATION ::= =OPTION {space OPTION}
94 -- COMMANDS_TRANSLATION ::= =? ARGS space command-name
95 -- ALPHANUMPLUS_TRANSLATION ::= =| UNIX_SWITCH |
97 -- UNIX_SWITCHES ::= UNIX_SWITCH {, UNIX_SWITCH}
99 -- UNIX_SWITCH ::= unix-switch-string | !unix-switch-string | `string'
101 -- OPTION ::= option-name space UNIX_SWITCHES
103 -- ARGS ::= -cargs | -bargs | -largs
105 -- Here command-qual is the name of the switch recognized by the GNATCmd.
106 -- This is always given in upper case in the templates, although in the
107 -- actual commands, either upper or lower case is allowed.
109 -- The unix-switch-string always starts with a minus, and has no commas
110 -- or spaces in it. Case is significant in the unix switch string. If a
111 -- unix switch string is preceded by the not sign (!) it means that the
112 -- effect of the corresponding command qualifier is to remove any previous
113 -- occurrence of the given switch in the command line.
115 -- The DIRECTORIES_TRANSLATION format is used where a list of directories
116 -- is given. This possible corresponding formats recognized by GNATCmd are
117 -- as shown by the following example for the case of PATH
119 -- PATH=direc
120 -- PATH=(direc,direc,direc,direc)
122 -- When more than one directory is present for the DIRECTORIES case, then
123 -- multiple instances of the corresponding unix switch are generated,
124 -- with the file name being substituted for the occurrence of *.
126 -- The FILE_TRANSLATION format is similar except that only a single
127 -- file is allowed, not a list of files, and only one unix switch is
128 -- generated as a result.
130 -- the NO_SPACE_FILE_TRANSL is similar to FILE_TRANSLATION, except that
131 -- no space is inserted between the switch and the file name.
133 -- The NUMERIC_TRANSLATION format is similar to the FILE_TRANSLATION case
134 -- except that the parameter is a decimal integer in the range 0 to 999.
136 -- For the OPTIONS_TRANSLATION case, GNATCmd similarly permits one or
137 -- more options to appear (although only in some cases does the use of
138 -- multiple options make logical sense). For example, taking the
139 -- case of ERRORS for GCC, the following are all allowed:
141 -- /ERRORS=BRIEF
142 -- /ERRORS=(FULL,VERBOSE)
143 -- /ERRORS=(BRIEF IMMEDIATE)
145 -- If no option is provided (e.g. just /ERRORS is written), then the
146 -- first option in the list is the default option. For /ERRORS this
147 -- is NORMAL, so /ERRORS with no option is equivalent to /ERRORS=NORMAL.
149 -- The COMMANDS_TRANSLATION case is only used for gnatmake, to correspond
150 -- to the use of -cargs, -bargs and -largs (the ARGS string as indicated
151 -- is one of these three possibilities). The name given by COMMAND is the
152 -- corresponding command name to be used to interpret the switches to be
153 -- passed on. Switches of this type set modes, e.g. /COMPILER_QUALIFIERS
154 -- sets the mode so that all subsequent switches, up to another switch
155 -- with COMMANDS_TRANSLATION apply to the corresponding commands issued
156 -- by the make utility. For example
158 -- /COMPILER_QUALIFIERS /LIST /BINDER_QUALIFIERS /MAIN
159 -- /COMPILER_QUALIFIERS /NOLIST /COMPILE_CHECKS=SYNTAX
161 -- Clearly these switches must come at the end of the list of switches
162 -- since all subsequent switches apply to an issued command.
164 -- For the DIRECT_TRANSLATION case, an implicit additional qualifier
165 -- declaration is created by prepending NO to the name of the qualifier,
166 -- and then inverting the sense of the UNIX_SWITCHES string. For example,
167 -- given the qualifier definition:
169 -- "/LIST -gnatl"
171 -- An implicit qualifier definition is created:
173 -- "/NOLIST !-gnatl"
175 -- In the case where, a ! is already present, inverting the sense of the
176 -- switch means removing it.
179 -- A synonym to shorten the table
182 -- String pointer type used throughout
185 -- Type used for array of switches

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

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

1521 -- /FORCE_ALI
1522 --
1523 -- In normal operation mode, the .ALI file is not generated if any
1524 -- illegalities are detected in the program. The use of this qualifier
1525 -- forces generation of the .ALI file. This file is marked as being

1603 --
1604 -- 1 The basic character set is Latin-1. This character
1605 -- set is defined by ISO standard 8859, part 1. The lower
1606 -- half (character codes 16#00# ... 16#7F#) is identical
1607 -- to standard ASCII coding, but the upper half is used
1608 -- to represent additional characters. This includes
1609 -- extended letters used by European languages, such as
1610 -- the umlaut used in German.
1611 --
1612 -- You may use any of these extended characters freely
1613 -- in character or string literals. In addition, the
1614 -- extended characters that represent letters can be
1615 -- used in identifiers.
1616 --

1618 -- and lowercase equivalence.
1619 --
1620 -- 3 Latin-3 letters allowed in identifiers, with uppercase
1621 -- and lower case equivalence.
1622 --
1623 -- 4 Latin-4 letters allowed in identifiers, with uppercase
1624 -- and lower case equivalence.
1625 --
1626 -- PC IBM PC code page 437. This code page is the normal
1627 -- default for PCs in the U.S. It corresponds to the
1628 -- original IBM PC character set. This set has some, but
1629 -- not all, of the extended Latin-1 letters, but these
1630 -- letters do not have the same encoding as Latin-1. In
1631 -- this mode, these letters are allowed in identifiers
1632 -- with uppercase and lowercase equivalence.
1633 --
1634 -- PC850 This code page (850) is a modification of 437 extended
1635 -- to include all the Latin-1 letters, but still not with
1636 -- the usual Latin-1 encoding. In this mode, all these
1637 -- letters are allowed in identifiers with uppercase and
1638 -- lower case equivalence.
1639 --
1640 -- FULL_UPPER Any character in the range 80-FF allowed in
1641 -- identifiers, and all are considered distinct. In
1642 -- other words, there are no uppercase and lower case
1643 -- equivalences in this range.
1644 --
1645 -- NO_UPPER No upper-half characters in the range 80-FF are

1656 -- NODOC (see /IDENTIFIER_CHARACTER_SET)
1660 -- /IGNORE_REP_CLAUSES
1661 --
1662 -- Causes all representation clauses to be ignored and treated as

1664 -- is used to analyze such code).
1668 -- /NOIMMEDIATE_ERRORS (D)
1669 -- /IMMEDIATE_ERRORS
1670 --
1671 -- Causes errors to be displayed as soon as they are encountered, rather
1672 -- than after compilation is terminated. If GNAT terminates prematurely
1673 -- or goes into an infinite loop, the last error message displayed may
1674 -- help to pinpoint the culprit.
1683 -- /NOINLINE (D)
1684 -- /INLINE[=keyword]
1685 --
1686 -- Selects the level of inlining for your program. In the absence of this
1687 -- qualifier, GNAT does not attempt inlining across units and does not
1688 -- need to access the bodies of subprograms for which "pragma Inline" is
1689 -- specified if they are not in the current unit.
1690 --
1691 -- The supported keywords are as follows:
1692 --
1693 -- PRAGMA (D) Recognize and process "Inline" pragmas. However,
1694 -- for the inlining to actually occur, optimization
1695 -- must be enabled. This enables inlining across unit
1696 -- boundaries, that is, inlining a call in one unit of
1697 -- a subprogram declared in a with'ed unit. The compiler
1698 -- will access these bodies, creating an extra source
1699 -- dependency for the resulting object file, and where
1700 -- possible, the call will be inlined.
1701 --
1702 -- This qualifier also turns on full optimization and
1703 -- requests GNAT to try to attempt automatic inlining
1704 -- of small subprograms within a unit.
1705 --
1706 -- Specifying /OPTIMIZE=NONE will disable the main effect
1707 -- of this qualifier, but you may specify other
1708 -- optimization options, to get either lower
1709 -- (/OPTIMIZE=SOME) or higher (/OPTIMIZE=UNROLL_LOOPS)
1710 -- levels of optimization.
1711 --
1712 -- FULL Front end inlining. The front end inlining activated
1713 -- by this switch is generally more extensive, and quite
1714 -- often more effective than the standard PRAGMA inlining
1715 -- mode. It will also generate additional dependencies.
1716 --
1717 -- SUPPRESS Suppresses all inlining, even if other optimization
1718 -- or inlining switches are set.

1772 --
1773 -- Cause a full machine code listing of the file to be generated to

1775 -- qualifier is also present.
1779 -- /MAPPING_FILE=file_name
1780 --
1781 -- Use mapping file file_name
1782 --
1783 -- A mapping file is a way to communicate to the compiler two mappings:
1784 -- from unit names to file names (without any directory information) and
1785 -- from file names to path names (with full directory information).
1786 -- These mappings are used by the compiler to short-circuit the path
1787 -- search.
1788 --
1789 -- The use of mapping files is not required for correct operation of the
1790 -- compiler, but mapping files can improve efficiency, particularly when
1791 -- sources are read over a slow network connection. In normal operation,
1792 -- you need not be concerned with the format or use of mapping files,
1793 -- and /MAPPING_FILE is not a qualifier that you would use explicitly.
1794 -- It is intended only for use by automatic tools such as GNAT MAKE
1795 -- running under the project file facility. The description here of the
1796 -- format of mapping files is provided for completeness and for possible
1797 -- use by other tools.
1798 --
1799 -- A mapping file is a sequence of sets of three lines. In each set, the
1800 -- first line is the unit name, in lower case, with "%s" appended for
1801 -- specifications and "%b" appended for bodies; the second line is the
1802 -- file name; and the third line is the path name.
1803 --
1804 -- Example:
1805 --
1806 -- main%b
1807 -- main.2_ada
1808 -- /gnat/project1/sources/main.2_ada
1809 --
1810 -- When qualifier ?MAPPING_FILE is specified, the compiler will create in
1811 -- memory the two mappings from the specified file. If there is any
1812 -- problem (non existent file, truncated file or duplicate entries),
1813 -- no mapping will be created.
1814 --
1815 -- Several /MAPPING_FILE qualifiers may be specified; however, only the
1816 -- last one on the command line will be taken into account.
1817 --
1818 -- When using a project file, GNAT MAKE creates a temporary mapping file
1819 -- and communicates it to the compiler using this switch.
1828 -- /MESSAGES_PROJECT_FILE[=messages-option]
1829 --
1830 -- Specifies the "verbosity" of the parsing of project files.
1831 -- messages-option may be one of the following:
1832 --
1833 -- DEFAULT (D) No messages are output if there is no error or warning.
1834 --
1835 -- MEDIUM A small number of messages are output.
1836 --
1837 -- HIGH A great number of messages are output, most of them not
1838 -- being useful for the user.
1842 -- /MAX_NESTING=nnn
1843 --
1844 -- Set maximum level of nesting of constructs (including subprograms,
1845 -- loops, blocks, packages, and conditionals).
1846 -- The level of nesting must not exceed the given value nnn.
1847 -- A value of zero disable this style check (not enabled by default).
1851 -- /NO_GNAT_ADC
1852 --
1853 -- Cause the compiler to ignore any configuration pragmas file GNAT.ADC
1854 -- in the default directory. Implied by qualifier /PROJECT_FILE.
1855 -- Often used in conjunction with qualifier /CONFIGURATION_PRAGMAS_FILE.
1859 -- /NOLOAD
1860 --
1861 -- Cause the compiler to operate in semantic check mode with full
1862 -- checking for all illegalities specified in the reference manual, but
1863 -- without generation of any source code (no object or ALI file
1864 -- generated).
1865 --
1866 -- Since dependent files must be accessed, you must follow the GNAT
1867 -- semantic restrictions on file structuring to operate in this mode:
1868 --
1869 -- o The needed source files must be accessible.
1870 -- o Each file must contain only one compilation unit.
1871 -- o The file name and unit name must match.
1872 --
1873 -- The output consists of error messages as appropriate. No object file
1874 -- or ALI file is generated. The checking corresponds exactly to the
1875 -- notion of legality in the Ada reference manual.
1876 --
1877 -- Any unit can be compiled in semantics-checking-only mode, including
1878 -- units that would not normally be compiled (generic library units,
1879 -- subunits, and specifications where a separate body is present).
1883 -- /NOSTD_INCLUDES
1884 --
1885 -- Do not look in the default directory for source files of the runtime.
1889 -- /NOSTD_LIBRARIES
1890 --
1891 -- Do not look for library files in the system default directory.
1910 -- /NOOPTIMIZE (D)
1911 -- /OPTIMIZE[=(keyword[,...])]
1912 --
1913 -- Selects the level of optimization for your program. The supported
1914 -- keywords are as follows:
1915 --
1916 -- ALL (D) Perform most optimizations, including those that
1917 -- may be expensive.
1918 --
1919 -- NONE Do not do any optimizations. Same as /NOOPTIMIZE.
1920 --
1921 -- SOME Perform some optimizations, but omit ones that
1922 -- are costly in compilation time.
1923 --
1924 -- SPACE Optimize space usage
1925 --
1926 -- DEVELOPMENT Same as SOME.
1927 --
1928 -- INLINING Full optimization, and also attempt automatic inlining
1929 -- of small subprograms within a unit
1930 --
1931 -- UNROLL_LOOPS Try to unroll loops. This keyword may be specified
1932 -- with any keyword above other than NONE. Loop
1933 -- unrolling usually, but not always, improves the
1934 -- performance of programs.
1935 --
1936 -- NO_STRICT_ALIASING
1937 -- Suppress aliasing analysis. When optimization is
1938 -- enabled (ALL or SOME above), the compiler assumes
1939 -- that pointers do in fact point to legitimate values
1940 -- of the pointer type (allocated from the proper pool).
1941 -- If this assumption is violated, e.g. by the use of
1942 -- unchecked conversion, then it may be necessary to
1943 -- suppress this assumption using this keyword (which
1944 -- may be specified only in conjunction with any
1945 -- keyword above, other than NONE).
1949 -- NODOC (see /OPTIMIZE)
1953 -- /OUTPUT_FILE=fname
1954 --
1955 -- This has the same effect as /LIST except that the output is written
1956 -- to a file instead of to standard output. If the given fname
1957 -- does not start with a period, then it is the full name of the file
1958 -- to be written. If fname starts with a period, the name of the file
1959 -- is the concatenation of to the name of the file being compiled with
1960 -- fname where the period is replace by an underline. For example, if
1961 -- file xyz.adb is compiled with -gnatl=.lst, then the output is written
1962 -- to file xyz.adb_lst.
1973 -- /POINTER_SIZE=64 (D)
1974 -- /POINTER_SIZE[=(keyword[,...])]
1975 --
1976 -- Change how pointers and descriptors are allocated. The following
1977 -- keywords are supported:
1978 --
1979 -- 64 (D) Allocate heap pointers in 64bit space except as
1980 -- constrained by a 32bit size clause or by
1981 -- Convention_C and generate 64bit descriptors for
1982 -- Descriptor mechanisms for calling imported
1983 -- subprograms and accept both 64bit and 32bit
1984 -- descriptors for calls to exported subprograms.
1985 --
1986 -- LONG Equivalent to option 64.
1987 --
1988 -- 32 Allocate all heap pointers in 32bit space and
1989 -- generate 32bit descriptors for Descriptor
1990 -- mechanisms for calling imported subprograms.
1991 --
1992 -- SHORT Equivalent to option 32.
1996 -- /NOPOLLING (D)
1997 -- /POLLING
1998 --
1999 -- Enable polling. See the description of pragma Polling in the GNAT
2000 -- Reference Manual for full details.
2004 -- /PROJECT_FILE=filename
2005 --
2006 -- Specifies the main project file to be used. The project files rooted
2007 -- at the main project file will be parsed before the invocation of the
2008 -- compiler. The source and object directories to be searched will be
2009 -- communicated to the compiler through logical names
2010 -- ADA_PRJ_INCLUDE_FILE and ADA_PRJ_OBJECTS_FILE.
2014 -- /PRINT_STANDARD
2015 --
2016 -- cause the compiler to output a representation of package Standard
2017 -- in a form very close to standard Ada. It is not quite possible to
2018 -- do this and remain entirely Standard (since new numeric base types
2019 -- cannot be created in standard Ada), but the output is easily
2020 -- readable to any Ada programmer, and is useful to determine the
2021 -- characteristics of target dependent types in package Standard.
2026 -- /NO_TREAT_RESTRICTIONS_AS_WARNINGS (D)
2027 -- /TREAT_RESTRICTIONS_AS_WARNINGS
2028 --
2029 -- Causes all restrictions to be treated as warnings (pragma Restriction

2044 -- /NOREPORT_ERRORS (D)
2045 -- /REPORT_ERRORS[=(keyword[,...])]
2046 --
2047 -- Change the way errors are reported. The following keywords are

2050 -- VERBOSE (D) Verbose mode. Full error output with source lines
2051 -- to SYS$OUTPUT.
2052 --
2053 -- BRIEF Generate the brief format error messages to
2054 -- SYS$OUTPUT as well as the verbose format message or
2055 -- full listing.
2056 --
2057 -- FULL Normally, the compiler suppresses error messages that
2058 -- are likely to be redundant. This keyword causes all
2059 -- error messages to be generated. One particular effect
2060 -- is for the case of references to undefined variables.
2061 -- If a given variable is referenced several times, the
2062 -- normal format of messages produces one error. With
2063 -- FULL, each undefined reference produces a separate
2064 -- error message.
2065 --
2066 -- IMMEDIATE Normally, the compiler saves up error messages and
2067 -- generates them at the end of compilation in proper
2068 -- sequence. This keyword causes error messages to be
2069 -- generated as soon as they are detected. The use of
2070 -- IMMEDIATE usually causes error messages to be
2071 -- generated out of sequence. Use it when the compiler
2072 -- blows up due to an internal error. In this case, the
2073 -- error messages may be lost. Sometimes blowups are
2074 -- the result of mishandled error messages, so you may
2075 -- want to run with this keyword to determine whether
2076 -- any error messages were generated.
2077 --
2078 -- DEFAULT Turn off VERBOSE and BRIEF. Same as /NOREPORT_ERRORS.
2082 -- NODOC (see /REPORT_ERRORS)

2272 -- 3, ATTRIBUTE, BLANKS, COMMENTS, END, VTABS,
2273 -- HTABS, IF_THEN, KEYWORD, LAYOUT, LINE_LENGTH,
2274 -- PRAGMA, REFERENCES, SPECS, TOKEN.
2275 --
2276 -- 1 .. 9 Specify indentation level from 1 to 9.
2277 -- The general style of required indentation is as

2327 -- gnatprep (where --! is used) and the SPARK
2328 -- annotation language (where --# is used).
2329 -- For the purposes of this rule, a special
2330 -- character is defined as being in one of the
2331 -- ASCII ranges 16#21#..16#2F# or
2332 -- 16#3A#..16#3F#.
2333 --
2334 -- * A line consisting entirely of minus signs,
2335 -- possibly preceded by blanks, is permitted.
2336 -- This allows the construction of box
2337 -- comments where lines of minus signs are
2338 -- used to form the top and bottom of the box.
2339 --
2340 -- * If a comment starts and ends with "--" is
2341 -- permitted as long as at least one blank
2342 -- follows the initial "--". Together with
2343 -- the preceding rule, this allows the
2344 -- construction of box comments, as shown in
2345 -- the following example:
2346 --
2347 -- ---------------------------
2348 -- -- This is a box comment --
2349 -- ---------------------------
2350 --
2351 -- DOS_LINE_ENDINGS Check that no DOS line terminators are present
2352 -- All lines must be terminated by a single
2353 -- ASCII.LF character. In particular the DOS line
2354 -- terminator sequence CR / LF is not allowed).
2355 --
2356 -- END Check end/exit labels.
2357 -- Optional labels on end statements ending
2358 -- subprograms and on exit statements exiting
2359 -- named loops, are required to be present.
2360 --
2361 -- GNAT Enforces a set of style conventions that
2362 -- match the style used in the GNAT source code.
2363 -- This maybe useful when developing code that
2364 -- is eventually intended to be incorporated into
2365 -- GNAT. For further details, see GNAT sources.
2366 --
2367 -- HTABS No horizontal tabs.
2368 -- Horizontal tab characters are not permitted in
2369 -- the source text. Together with the BLANKS
2370 -- (no blanks at end of line) option, this
2371 -- enforces a canonical form for the use of blanks
2372 -- to separate source tokens.
2373 --
2374 -- IF_THEN Check if-then layout.
2375 -- The keyword then must appear either on the
2376 -- same line as the corresponding if, or on a line
2377 -- on its own, lined up under the if with at least
2378 -- one non-blank line in between containing all or
2379 -- part of the condition to be tested.
2380 --
2381 -- KEYWORD Check keyword casing.
2382 -- All keywords must be in lower case (with the
2383 -- exception of keywords such as digits used as
2384 -- attribute names to which this check does not
2385 -- apply).
2386 --
2387 -- LAYOUT Check layout.
2388 -- Layout of statement and declaration constructs
2389 -- must follow the recommendations in the Ada
2390 -- Reference Manual, as indicated by the form of
2391 -- the syntax rules. For example an else keyword
2392 -- must be lined up with the corresponding if
2393 -- keyword.
2394 --
2395 -- There are two respects in which the style rule
2396 -- enforced by this check option are more liberal
2397 -- than those in the Ada Reference Manual.
2398 -- First in the case of record declarations,
2399 -- it is permissible to put the record keyword on
2400 -- the same line as the type keyword, and then
2401 -- the end in end record must line up under type.
2402 -- For example, either of the following two
2403 -- layouts is acceptable:
2404 --
2405 -- type q is record
2406 -- a : integer;
2407 -- b : integer;
2408 -- end record;
2409 --
2410 -- type q is
2411 -- record
2412 -- a : integer;
2413 -- b : integer;
2414 -- end record;
2415 --
2416 -- Second, in the case of a block statement,
2417 -- a permitted alternative is to put the block
2418 -- label on the same line as the declare or begin
2419 -- keyword, and then line the end keyword up under
2420 -- the block label. For example both the following
2421 -- are permitted:
2422 --
2423 --
2424 --
2425 -- Block : declare
2426 -- A : Integer := 3;
2427 -- begin
2428 -- Proc (A, A);
2429 -- end Block;
2430 --
2431 -- Block :
2432 -- declare
2433 -- A : Integer := 3;
2434 -- begin
2435 -- Proc (A, A);
2436 -- end Block;
2437 --
2438 -- The same alternative format is allowed for
2439 -- loops. For example, both of the following are
2440 -- permitted:
2441 --
2442 --
2443 --
2444 -- Clear : while J < 10 loop
2445 -- A (J) := 0;
2446 -- end loop Clear;
2447 --
2448 -- Clear :
2449 -- while J < 10 loop
2450 -- A (J) := 0;
2451 -- end loop Clear;
2452 --
2453 --
2454 --
2455 -- LINE_LENGTH Check maximum line length.
2456 -- The length of source lines must not exceed 79
2457 -- characters, including any trailing blanks
2458 -- The value of 79 allows convenient display on
2459 -- an 80 character wide device or window, allowing
2460 -- for possible special treatment of 80 character
2461 -- lines.
2462 --
2463 -- NONE Clear any previously set style checks.
2464 --
2465 -- ORDERED_SUBPROGRAMS Check order of subprogram bodies.
2466 -- All subprogram bodies in a given scope (e.g.
2467 -- a package body) must be in alphabetical order.
2468 -- The ordering rule uses normal Ada rules for
2469 -- comparing strings, ignoring casing of letters,
2470 -- except that if there is a trailing numeric
2471 -- suffix, then the value of this suffix is used
2472 -- in the ordering (e.g. Junk2 comes before
2473 -- Junk10).
2474 --
2475 -- PRAGMA Check pragma casing.
2476 -- Pragma names must be written in mixed case,
2477 -- that is, the initial letter and any letter
2478 -- following an underscore must be uppercase.
2479 -- All other letters must be lowercase.
2480 --
2481 -- REFERENCES Check references.
2482 -- All identifier references must be cased in the
2483 -- same way as the corresponding declaration.
2484 -- No specific casing style is imposed on
2485 -- identifiers. The only requirement is for
2486 -- consistency of references with declarations.
2487 --
2488 -- SPECS Check separate specs.
2489 -- Separate declarations ("specs") are required
2490 -- for subprograms (a body is not allowed to serve
2491 -- as its own declaration). The only exception is
2492 -- that parameterless library level procedures are
2493 -- not required to have a separate declaration.
2494 -- This exception covers the most frequent form of
2495 -- main program procedures.
2496 --
2497 -- STANDARD_CASING Check casing of entities in Standard.
2498 -- Any identifier from Standard must be cased to
2499 -- match the presentation in the Ada Reference
2500 -- Manual (for example, Integer and ASCII.NUL).
2501 --
2502 -- TOKEN Check token spacing.
2503 -- The following token spacing rules are enforced:
2504 --
2505 -- * The keywords abs and not must be followed
2506 -- by a space.
2507 --
2508 -- * The token => must be surrounded by spaces.
2509 --
2510 -- * The token <> must be preceded by a space or
2511 -- a left parenthesis.
2512 --
2513 -- * Binary operators other than ** must be
2514 -- surrounded by spaces. There is no
2515 -- restriction on the layout of the ** binary
2516 -- operator.
2517 --
2518 -- * Colon must be surrounded by spaces.
2519 --
2520 -- * Colon-equal (assignment) must be surrounded
2521 -- by spaces.
2522 --
2523 -- * Comma must be the first non-blank character
2524 -- on the line, or be immediately preceded by
2525 -- a non-blank character, and must be followed
2526 -- by a space.
2527 --
2528 -- * If the token preceding a left paren ends
2529 -- with a letter or digit, then a space must
2530 -- separate the two tokens.
2531 --
2532 -- * A right parenthesis must either be the
2533 -- first non-blank character on a line, or it
2534 -- must be preceded by a non-blank character.
2535 --
2536 -- * A semicolon must not be preceded by
2537 -- a space, and must not be followed by
2538 -- a non-blank character.
2539 --
2540 -- * A unary plus or minus may not be followed
2541 -- by a space.
2542 --
2543 -- * A vertical bar must be surrounded by
2544 -- spaces.
2545 --
2546 -- In the above rules, appearing in column one is
2547 -- always permitted, that is, counts as meeting
2548 -- either a requirement for a required preceding
2549 -- space, or as meeting a requirement for no
2550 -- preceding space.
2551 --
2552 -- Appearing at the end of a line is also always
2553 -- permitted, that is, counts as meeting either
2554 -- a requirement for a following space,
2555 -- or as meeting a requirement for no following
2556 -- space.
2557 --
2558 -- UNNECESSARY_BLANK_LINES
2559 -- Check for unnecessary blank lines.
2560 -- A blank line is considered unnecessary if it
2561 -- appears at the end of the file, or if more
2562 -- than one blank line occurs in sequence.
2563 --
2564 -- VTABS No form feeds or vertical tabs.
2565 -- Form feeds or vertical tab characters are not
2566 -- permitted in the source text.
2567 --
2568 -- XTRA_PARENS Check for the use of an unnecessary extra
2569 -- level of parentheses (C - style) around
2570 -- conditions in if statements, while statements
2571 -- and exit statements.
2575 -- NODOC (see /STYLE_CHECKS)
2579 -- /SUBDIRS=dir
2580 --
2581 -- The actual directories (object, exec, library, ...) are subdirectories
2582 -- of the directory specified in the project file. If the subdirectory
2583 -- does not exist, it is created automatically.
2587 -- /SYMBOL_PREPROCESSING="symbol=value"
2588 --
2589 -- Define or redefine a preprocessing symbol, associated with value.
2590 -- If "=value" is not specified, then the value of the symbol is True.
2591 -- A symbol is an identifier, following normal Ada (case-insensitive)
2592 -- rules for its syntax, and value is any sequence (including an empty
2593 -- sequence) of characters from the set (letters, digits, period,
2594 -- underline). Ada reserved words may be used as symbols, with the
2595 -- exceptions of "if", "else", "elsif", "end", "and", "or" and "then".
2596 --
2597 -- A symbol declared with this qualifier on the command line replaces
2598 -- a symbol with the same name either in a definition file or specified
2599 -- with a switch -D in the preprocessor data file.
2600 --
2601 -- This qualifier is similar to qualifier /ASSOCIATE of
2602 -- GNAT PREPROCESSING.
2606 -- /NOSYNTAX_ONLY (D)
2607 -- /SYNTAX_ONLY
2608 --
2609 -- Run GNAT in syntax checking only mode. You can check a series of
2610 -- files in a single command, and can use wild cards to specify such a
2611 -- group of files.
2612 --
2613 -- You may use other qualifiers in conjunction with this qualifier. In
2614 -- particular, /LIST and /REPORT_ERRORS=VERBOSE are useful to control the
2615 -- format of any generated error messages.
2616 --
2617 -- The output is simply the error messages, if any. No object file or ALI
2618 -- file is generated by a syntax-only compilation. Also, no units other
2619 -- than the one specified are accessed. For example, if a unit "X" with's
2620 -- a unit "Y", compiling unit "X" in syntax check only mode does not
2621 -- access the source file containing unit "Y".
2622 --
2623 -- Normally, GNAT allows only a single unit in a source file. However,
2624 -- this restriction does not apply in syntax-check-only mode, and it is
2625 -- possible to check a file containing multiple compilation units
2626 -- concatenated together. This is primarily used by the GNAT CHOP
2627 -- command.
2631 -- /TABLE_MULTIPLIER=nnn
2632 --
2633 -- All compiler tables start at nnn times usual starting size.
2637 -- /TRACE_UNITS
2638 -- /NOTRACE_UNITS
2639 --
2640 -- This switch that does for the frontend what /VERBOSE does for the
2641 -- backend. The system prints the name of each unit, either a compilation
2642 -- unit or nested unit, as it is being analyzed.
2646 -- /TREE_OUTPUT
2647 -- /NOTREE_OUTPUT
2648 --
2649 -- Cause GNAT to write the internal tree for a unit to a file (with the
2650 -- filetype ATB for a body or ATS for a spec). This is not normally
2651 -- required, but is used by separate analysis tools. Typically these
2652 -- tools do the necessary compilations automatically, so you should never
2653 -- have to specify this switch in normal operation.
2657 -- /TRY_SEMANTICS
2658 -- /NOTRY_SEMANTICS
2659 --
2660 -- In normal operation mode the compiler first parses the program and
2661 -- determines if there are any syntax errors. If there are, appropriate
2662 -- error messages are generated and compilation is immediately
2663 -- terminated. This qualifier tells GNAT to continue with semantic
2664 -- analysis even if syntax errors have been found. This may enable the
2665 -- detection of more errors in a single run. On the other hand, the
2666 -- semantic analyzer is more likely to encounter some internal fatal
2667 -- error when given a syntactically invalid tree.
2671 -- /NOUNITS_LIST (D)
2672 -- /UNITS_LIST
2673 --
2674 -- Print a list of units required by this compilation on SYS$OUTPUT. The
2675 -- listing includes all units on which the unit being compiled depends
2676 -- either directly or indirectly.
2680 -- /NOUNIQUE_ERROR_TAG (D)
2681 -- /UNIQUE_ERROR_TAG
2682 --
2683 -- Tag compiler error messages with the string "error: ".
2687 -- /NOUPPERCASE_EXTERNALS (D)
2688 -- /UPPERCASE_EXTERNALS
2689 --
2690 -- Fold default and explicit external names in pragmas Import and Export
2691 -- to uppercase for compatibility with the default behavior of DEC C.
2742 -- /VALIDITY_CHECKING[=(keyword,[...])]
2743 --
2744 -- Control level of validity checking.
2745 --
2746 -- DEFAULT (D) In this mode checks are made to prevent
2747 -- erroneous behavior in accordance with the RM.
2748 -- Notably extra checks may be needed for case
2749 -- statements and subscripted array assignments.
2750 --
2751 -- NONE No special checks for invalid values are
2752 -- performed. This means that references to
2753 -- uninitialized variables can cause erroneous
2754 -- behavior from constructs like case statements
2755 -- and subscripted array assignments. In this
2756 -- mode, invalid values can lead to erroneous
2757 -- behavior.
2758 --
2759 -- FULL Every assignment is checked for validity, so
2760 -- that it is impossible to assign invalid values.
2761 -- The RM specifically allows such assignments,
2762 -- but in this mode, invalid values can never be
2763 -- assigned, and an attempt to perform such an
2764 -- assignment immediately raises Constraint_Error.
2765 -- This behavior is allowed (but not required) by
2766 -- the RM. This mode is intended as a debugging aid,
2767 -- and may be useful in helping to track down
2768 -- uninitialized variables. It may be useful to
2769 -- use this in conjunction with the Normalize_Scalars
2770 -- pragma which attempts to initialize with invalid
2771 -- values where possible.
2775 -- /VERBOSE
2776 -- /NOVERBOSE
2777 --
2778 -- Show commands generated by the GCC driver. Normally used only for
2779 -- debugging purposes or if you need to be sure what version of the
2780 -- compiler you are executing.
2784 -- /NOASM (D)
2785 -- /ASM
2786 --
2787 -- Use to cause the assembler source file to be generated, using S as the
2788 -- filetype, instead of the object file. This may be useful if you need
2789 -- to examine the generated assembly code.
2934 -- /NOWARNINGS
2935 --
2936 -- Suppress the output of all warning messages from the GNAT front end.
2937 -- Note that it does not suppress warnings from the gcc back end.
2938 --
2939 -- /WARNINGS[=(keyword[,...])]
2940 --
2941 -- In addition to error messages, corresponding to illegalities as
2942 -- defined in the reference manual, the compiler detects two kinds of
2943 -- warning situations. First, the compiler considers some constructs
2944 -- suspicious and generates a warning message to alert you to a possible
2945 -- error. Second, if the compiler detects a situation that is sure to
2946 -- raise an exception at runtime, it generates a warning message.
2947 --
2948 -- You may specify the following keywords to change this behavior:
2949 --
2950 -- DEFAULT (D) The default behavior above.
2951 --
2952 -- ALL Activate all optional warnings.
2953 -- Activates most optional warning messages,
2954 -- see remaining list in this section for
2955 -- details on optional warning messages that
2956 -- can be individually controlled.
2957 -- The warnings that are not turned on by
2958 -- this option are BIASED_ROUNDING,
2959 -- IMPLICIT_DEREFERENCE, HIDING and
2960 -- ELABORATION. All other optional Ada
2961 -- warnings are turned on.
2962 --
2963 -- EVERY Activate every optional warning.
2964 -- Activates all optional warnings, including
2965 -- those listed above as exceptions for ALL.
2966 --
2967 -- NOALL Suppress all optional errors.
2968 -- Suppresses all optional warning messages
2969 -- that can be activated by option ALL.
2970 --
2971 -- ALL_GCC Request additional messages from the GCC
2972 -- backend. Most of these are not relevant
2973 -- to Ada.
2974 --
2975 -- CONDITIONALS Activate warnings for conditional
2976 -- Expressions used in tests that are known
2977 -- to be True or False at compile time. The
2978 -- default is that such warnings are not
2979 -- generated.
2980 --
2981 -- NOCONDITIONALS Suppress warnings for conditional
2982 -- expressions used in tests that are known
2983 -- to be True or False at compile time.
2984 --
2985 -- IMPLICIT_DEREFERENCE Activate warnings on implicit dereferencing.
2986 -- The use of a prefix of an access type in an
2987 -- indexed component, slice, or selected component
2988 -- without an explicit .all will generate
2989 -- a warning. With this warning enabled, access
2990 -- checks occur only at points where an explicit
2991 -- .all appears in the source code (assuming no
2992 -- warnings are generated as a result of this
2993 -- option). The default is that such warnings are
2994 -- not generated. Note that /WARNINGS=ALL does not
2995 -- affect the setting of this warning option.
2996 --
2997 -- NOIMPLICIT_DEREFERENCE Suppress warnings on implicit dereferencing.
2998 -- in indexed components, slices, and selected
2999 -- components.
3000 --
3001 -- ELABORATION Activate warnings on missing pragma
3002 -- Elaborate_All statements. The default is
3003 -- that such warnings are not generated.
3004 --
3005 -- NOELABORATION Suppress warnings on missing pragma
3006 -- Elaborate_All statements.
3007 --
3008 -- ERRORS Warning messages are to be treated as errors.
3009 -- The warning string still appears, but the
3010 -- warning messages are counted as errors, and
3011 -- prevent the generation of an object file.
3012 --
3013 -- HIDING Activate warnings on hiding declarations.
3014 -- A declaration is considered hiding if it is
3015 -- for a non-overloadable entity, and it declares
3016 -- an entity with the same name as some other
3017 -- entity that is directly or use-visible. The
3018 -- default is that such warnings are not
3019 -- generated.
3020 --
3021 -- NOHIDING Suppress warnings on hiding declarations.
3022 --
3023 -- IMPLEMENTATION Activate warnings for a with of an internal
3024 -- GNAT implementation unit, defined as any unit
3025 -- from the Ada, Interfaces, GNAT, DEC or
3026 -- System hierarchies that is not documented in
3027 -- either the Ada Reference Manual or the GNAT
3028 -- Programmer's Reference Manual. Such units are
3029 -- intended only for internal implementation
3030 -- purposes and should not be with'ed by user
3031 -- programs. The default is that such warnings
3032 -- are generated.
3033 --
3034 -- NOIMPLEMENTATION Disables warnings for a with of an internal
3035 -- GNAT implementation unit.
3036 --
3037 -- INEFFECTIVE_INLINE Activate warnings on ineffective pragma Inlines
3038 -- Activates warnings for failure of front end
3039 -- inlining (activated by /INLINE=FULL) to inline
3040 -- a particular call. There are many reasons for
3041 -- not being able to inline a call, including most
3042 -- commonly that the call is too complex to
3043 -- inline. This warning can also be turned on
3044 -- using /INLINE=FULL.
3045 --
3046 -- NOINEFFECTIVE_INLINE Suppress warnings on ineffective pragma Inlines
3047 -- Suppresses warnings on ineffective pragma
3048 -- Inlines. If the inlining mechanism cannot
3049 -- inline a call, it will simply ignore the
3050 -- request silently.
3051 --
3052 -- MISSING_COMPONENT_CLAUSES
3053 -- Activate warnings for cases when there are
3054 -- component clauses for a record type, but not
3055 -- for every component of the record.
3056 --
3057 -- NOMISSING_COMPONENT_CLAUSES
3058 -- Suppress warnings for cases when there are
3059 -- missing component clauses for a record type.
3060 --
3061 -- MISSING_PARENS
3062 -- Activate warnings for cases where parentheses
3063 -- are not used and the result is potential
3064 -- ambiguity from a reader's point of view.
3065 -- For example (not a > b) when a and b are
3066 -- modular means (not (a) > b) and very likely
3067 -- the programmer intended (not (a > b)).
3068 --
3069 -- NOMISSING_PARENS
3070 -- Suppress warnings for cases where parentheses
3071 -- are not used and the result is potential
3072 -- ambiguity from a reader's point of view.
3073 --
3074 -- MODIFIED_UNREF Activates warnings for variables that are
3075 -- assigned (using an initialization value or with
3076 -- one or more assignment statements) but whose
3077 -- value is never read. The warning is suppressed
3078 -- for volatile variables and also for variables
3079 -- that are renamings of other variables or for
3080 -- which an address clause is given. This warning
3081 -- can also be turned on using /WARNINGS/OPTIONAL.
3082 --
3083 -- NOMODIFIED_UNREF Disables warnings for variables that are
3084 -- assigned or initialized, but never read.
3085 --
3086 -- NORMAL Sets normal warning mode, in which enabled
3087 -- warnings are issued and treated as warnings
3088 -- rather than errors. This is the default mode.
3089 -- It can be used to cancel the effect of an
3090 -- explicit /WARNINGS=SUPPRESS or
3091 -- /WARNINGS=ERRORS. It also cancels the effect
3092 -- of the implicit /WARNINGS=ERRORS that is
3093 -- activated by the use of /STYLE=GNAT.
3094 --
3095 -- OBSOLESCENT Activates warnings for calls to subprograms
3096 -- marked with pragma Obsolescent and for use of
3097 -- features in Annex J of the Ada Reference
3098 -- Manual. In the case of Annex J, not all
3099 -- features are flagged. In particular use of the
3100 -- renamed packages (like Text_IO), use of package
3101 -- ASCII and use of the attribute 'Constrained are
3102 -- not flagged, since these are very common and
3103 -- would generate many annoying positive warnings.
3104 -- The default is that such warnings are not

3231 -- /NOWIDE_CHARACTER_ENCODING (D)
3232 -- /WIDE_CHARACTER_ENCODING[=encode-type]
3233 --
3234 -- Specifies the mechanism used to encode wide characters. 'encode-type'
3235 -- is one of the following:
3236 --
3237 -- BRACKETS (D) A wide character is encoded as ["xxxx"] where XXXX
3238 -- are four hexadecimal digits representing the coding
3239 -- ('Pos value) of the character in type
3240 -- Wide_Character. The hexadecimal digits may use upper
3241 -- or lower case letters.
3242 --
3243 -- This notation can also be used for upper half
3244 -- Character values using the format ["xx"] where XX is
3245 -- two hexadecimal digits representing the coding ('Pos
3246 -- value) of the character in type Character (or
3247 -- Wide_Character). The hexadecimal digits may use upper
3248 -- of lower case.
3249 --
3250 -- NONE No wide characters are allowed. Same
3251 -- as /NOWIDE_CHARACTER_ENCODING.
3252 --
3253 -- HEX In this encoding, a wide character is represented by
3254 -- the following five character sequence: ESC a b c d
3255 -- Where 'a', 'b', 'c', and 'd' are the four hexadecimal
3256 -- characters (using uppercase letters) of the wide
3257 -- character code. For example, ESC A345 is used to
3258 -- represent the wide character with code 16#A345#. This
3259 -- scheme is compatible with use of the full
3260 -- Wide_Character set.
3261 --
3262 -- UPPER The wide character with encoding 16#abcd# where the
3263 -- upper bit is on (in other words, "a" is in the range
3264 -- 8-F) is represented as two bytes, 16#ab# and 16#cd#.
3265 -- The second byte may never be a format control
3266 -- character, but is not required to be in the upper
3267 -- half. This method can be also used for shift-JIS or
3268 -- EUC, where the internal coding matches the external
3269 -- coding.
3270 --
3271 -- SHIFT_JIS A wide character is represented by a two-character
3272 -- sequence, 16#ab# and 16#cd#, with the restrictions
3273 -- described for upper-half encoding as described above.
3274 -- The internal character code is the corresponding JIS
3275 -- character according to the standard algorithm for
3276 -- Shift-JIS conversion. Only characters defined in the
3277 -- JIS code set table can be used with this encoding
3278 -- method.
3279 --
3280 -- UTF8 A wide character is represented using
3281 -- UCS Transformation Format 8 (UTF-8) as defined in Annex
3282 -- R of ISO 10646-1/Am.2. Depending on the character
3283 -- value, the representation is a one, two, or three byte
3284 -- sequence:
3285 --
3286 -- 16#0000#-16#007f#: 2#0xxxxxxx#
3287 -- 16#0080#-16#07ff#: 2#110xxxxx# 2#10xxxxxx#
3288 -- 16#0800#-16#ffff#: 2#1110xxxx# 2#10xxxxxx# 2#10xxxxxx#
3289 --
3290 -- where the xxx bits correspond to the left-padded bits
3291 -- of the 16-bit character value. Note that all lower
3292 -- half ASCII characters are represented as ASCII bytes
3293 -- and all upper half characters and other wide characters
3294 -- are represented as sequences of upper-half (The full
3295 -- UTF-8 scheme allows for encoding 31-bit characters as
3296 -- 6-byte sequences, but in this implementation, all UTF-8
3297 -- sequences of four or more bytes length will be treated
3298 -- as illegal).
3299 --
3300 -- EUC A wide character is represented by a two-character
3301 -- sequence 16#ab# and 16#cd#, with both characters being
3302 -- in the upper half. The internal character code is the
3303 -- corresponding JIS character according to the EUC
3304 -- encoding algorithm. Only characters defined in the JIS
3305 -- code set table can be used with this encoding method.
3309 -- NODOC (see /WIDE_CHARACTER_ENCODING)
3313 -- /NOXDEBUG (D)
3314 -- /XDEBUG
3315 --
3316 -- Output expanded source files for source level debugging.
3317 -- The expanded source (see /EXPAND_SOURCE) is written to files
3318 -- with names formed by appending "_DG" to the input file name,
3319 -- The debugging information generated by the /DEBUG qualifier will then
3320 -- refer to the generated file. This allows source level debugging using
3321 -- the generated code which is sometimes useful for complex code, for
3322 -- example to find out exactly which part of a complex construction
3323 -- raised an exception.
3330 -- /XREF[=keyword]
3331 --
3332 -- Normally the compiler generates full cross-referencing information in

4214 ----------------------------
4223 -- /ACTIONS=(keyword[,...])
4224 --
4225 -- GNAT MAKE default behavior is to check if the sources are up to date,
4226 -- compile those sources that are not up to date, bind the main source,
4227 -- then link the executable.
4228 --
4229 -- With the /ACTIONS qualifier, GNAT MAKE may be restricted to one or
4230 -- two of these three steps:
4231 --
4232 -- o Compile
4233 -- o Bind
4234 -- o Link
4235 --
4236 --
4237 -- You may specify one or more of the following keywords to the /ACTIONS
4238 -- qualifier:
4239 --
4240 -- BIND Bind only. Can be combined with /ACTIONS=COMPILE
4241 -- to do compilation and binding, but no linking.
4242 -- Can be combined with /ACTIONS=LINK to do binding and
4243 -- linking. When not combined with /ACTIONS=COMPILE,
4244 -- all the units in the closure of the main program must
4245 -- have been previously compiled and must be up to date.
4246 --
4247 -- COMPILE Compile only. Do not perform binding, except when
4248 -- /ACTIONS=BIND is also specified. Do not perform
4249 -- linking, except if both /ACTIONS=BIND and /ACTIONS=LINK
4250 -- are also specified.
4251 --
4252 -- LINK Link only. Can be combined with /ACTIONS=BIND to do
4253 -- binding and linking. Linking will not be performed
4254 -- if combined with /ACTIONS=COMPILE but not with
4255 -- /ACTIONS=BIND\. When not combined with /ACTIONS=BIND
4256 -- all the units in the closure of the main program must
4257 -- have been previously compiled and must be up to date,
4258 -- and the main program need to have been bound.

4263 --
4264 -- Add directories to the project search path.
4268 -- /NOALL_FILES (D)
4269 -- /ALL_FILES
4270 --
4271 -- Consider all files in the make process, even the GNAT internal system
4272 -- files (for example, the predefined Ada library files). By default,
4273 -- GNAT MAKE does not check these files (however, if there is an
4274 -- installation problem, it will be caught when GNAT MAKE binds your
4275 -- program). You may have to specify this qualifier if you are working on
4276 -- GNAT itself. The vast majority of GNAT MAKE users never need to
4277 -- specify this switch. All GNAT internal files with will be compiled
4278 -- with /STYLE_CHECK=GNAT.
4282 -- /NOALL_PROJECTS (D)
4283 -- /ALL_PROJECTS
4284 --
4285 -- Implies /Unique.
4286 -- When used without project files, it is equivalent to /UNIQUE.
4287 -- When used with a project file with no main (neither on the command
4288 -- line nor in the attribute Main) check every source of every project,
4289 -- recompile all sources that are not up to date and rebuild libraries
4290 -- if necessary.
4294 -- /BINDER_QUALIFIERS
4295 --
4296 -- Any qualifiers specified after this qualifier other than
4297 -- /COMPILER_QUALIFIERS, /LINKER_QUALIFIERS and /MAKE_QUALIFIERS will be
4298 -- passed to any GNAT BIND commands generated by GNAT MAKE.

4303 --
4304 -- Bind and link all sources of a project, without any consideration
4305 -- to attribute Main, if there is one. This qualifier need to be
4306 -- used in conjunction with the /PROJECT_FILE= qualifier and cannot
4307 -- be used with a main subprogram on the command line or for
4308 -- a library project file. As the binder is invoked with the option
4309 -- meaning "No Ada main subprogram", the user must ensure that the
4310 -- proper options are specified to the linker. This qualifier is
4311 -- normally used when the main subprogram is in a foreign language
4312 -- such as C.
4316 -- /COMPILER_QUALIFIERS
4317 --
4318 -- Any qualifiers specified after this qualifier other than
4319 -- /BINDER_QUALIFIERS, /LINKER_QUALIFIERS and /MAKE_QUALIFIERS will be

4334 -- To ease the programmer's task in case of compilation errors, the list

4336 -- terminates.
4340 -- /CURRENT_DIRECTORY (D)

4343 -- Look for source, library or object files in the default directory.
4347 -- /NODEPENDENCIES_LIST (D)
4348 -- /DEPENDENCIES_LIST
4349 --
4350 -- Check if all objects are up to date. If they are, output the object
4351 -- dependences to SYS$OUTPUT in a form that can be directly exploited in
4352 -- a Unix-style Makefile. By default, each source file is prefixed with
4353 -- its (relative or absolute) directory name. This name is whatever you
4354 -- specified in the various /SOURCE_SEARCH and /SEARCH qualifiers. If
4355 -- you also specify the /QUIET qualifier, only the source file names,
4356 -- without relative paths, are output. If you just specify the
4357 -- /DEPENDENCY_LIST qualifier, dependencies of the GNAT internal system
4358 -- files are omitted. This is typically what you want. If you also
4359 -- specify the /ALL_FILES qualifier, dependencies of the GNAT internal
4360 -- files are also listed. Note that dependencies of the objects in
4361 -- external Ada libraries (see the /SKIP_MISSING qualifier) are never
4362 -- reported.
4366 -- /DIRECTORY_OBJECTS=<file>
4367 --
4368 -- Put all object files and .ALI files in <file>.
4369 -- This qualifier is not compatible with /PROJECT_FILE.
4373 -- /NOPLAY_PROGRESS (D)
4374 -- /DISPLAY_PROGRESS
4375 --
4376 -- Display progress for each source, up to date or not, as a single line
4377 -- completed x out of y (zz%)
4378 -- If the file needs to be compiled this is displayed after the
4379 -- invocation of the compiler. These lines are displayed even in quiet
4380 -- output mode (/QUIET).
4384 -- /NODO_OBJECT_CHECK (D)
4385 -- /DO_OBJECT_CHECK
4386 --
4387 -- Don't compile, bind, or link. Output a single command that will
4388 -- recompile an out of date unit, if any. Repeated use of this option,
4389 -- followed by carrying out the indicated compilation, will eventually
4390 -- result in recompiling all required units.
4391 --
4392 -- If any ALI is missing during the process, GNAT MAKE halts and
4393 -- displays an error message.
4397 -- /EXECUTABLE=exec-name
4398 --
4399 -- The name of the final executable program will be 'exec_name'. If this
4400 -- qualifier is omitted the default name for the executable will be the

4428 -- internal files unless the /ALL_FILES qualifier is also specified.
4432 -- /NOFULL_PATH_IN_BRIEF_MESSAGES (D)
4433 -- /FULL_PATH_IN_BRIEF_MESSAGES
4434 --
4435 -- When using project files, if some errors or warnings are detected
4436 -- during parsing and verbose mode is not in effect (no use of qualifier
4437 -- /VERBOSE), then error lines start with the full path name of the

4442 -- /NOHIGH_VERBOSITY (D)
4443 -- /HIGH_VERBOSITY
4444 --
4445 -- Displays the reason for all recompilations GNAT MAKE decides are
4446 -- necessary, in high verbosity. Equivalent to /VERBOSE.
4450 -- /NOIN_PLACE (D)
4451 -- /IN_PLACE
4452 --
4453 -- In normal mode, GNAT MAKE compiles all object files and ALI files
4454 -- into the current directory. If the /IN_PLACE switch is used,
4455 -- then instead object files and ALI files that already exist are over-
4456 -- written in place. This means that once a large project is organized
4457 -- into separate directories in the desired manner, then GNAT MAKE will
4458 -- automatically maintain and update this organization. If no ALI files
4459 -- are found on the Ada object path, the new object and ALI files are
4460 -- created in the directory containing the source being compiled.
4464 -- /SOURCE_INDEX=nnn
4465 --
4466 -- Specifies the index of the units in the source file
4467 -- By default, source files are mono-unit and there is no index
4468 -- When /SOURCE_INDEX=nnn is specified, only one main may be specified
4469 -- on the command line.
4473 -- /LIBRARY_SEARCH=(directory[,...])
4474 --
4475 -- Add the specified directories to the list of directories in which the
4476 -- linker will search for libraries.
4480 -- /LINKER_QUALIFIERS
4481 --
4482 -- Any qualifiers specified after this qualifier other than
4483 -- /COMPILER_QUALIFIERS, /BINDER_QUALIFIERS and /MAKE_QUALIFIERS will be
4484 -- passed to any GNAT LINK commands generated by GNAT LINK.
4488 -- /NOLOW_VERBOSITY (D)
4489 -- /LOW_VERBOSITY
4490 --
4491 -- Displays the reason for all recompilations GNAT MAKE decides are
4492 -- necessary, in low verbosity, that is with less output than
4493 -- /MEDIUM_VERBOSITY, /HIGH_VERBOSITY or /VERBOSE.
4497 -- /MAKE_QUALIFIERS
4498 --
4499 -- Any qualifiers specified after this qualifier other than
4500 -- /COMPILER_QUALIFIERS, /BINDER_QUALIFIERS and /LINKER_QUALIFIERS
4501 -- are for the benefit of GNAT MAKE itself.
4505 -- /NOMAPPING (D)
4506 -- /MAPPING
4507 --
4508 -- Use a mapping file. A mapping file is a way to communicate to the
4509 -- compiler two mappings: from unit names to file names (without any
4510 -- directory information) and from file names to path names (with full
4511 -- directory information). These mappings are used by the compiler to
4512 -- short-circuit the path search. When GNAT MAKE is invoked with this
4513 -- qualifier, it will create a mapping file, initially populated by the
4514 -- project manager, if /PROJECT_File= is used, otherwise initially empty.
4515 -- Each invocation of the compiler will add the newly accessed sources to
4516 -- the mapping file. This will improve the source search during the next
4517 -- invocations of the compiler
4521 -- /NOMEDIUM_VERBOSITY (D)
4522 -- /MEDIUM_VERBOSITY
4523 --
4524 -- Displays the reason for all recompilations GNAT MAKE decides are

4526 -- than /HIGH_VERBOSITY or /VERBOSE.
4535 -- /MESSAGES_PROJECT_FILE[=messages-option]
4536 --
4537 -- Specifies the "verbosity" of the parsing of project files.
4538 -- messages-option may be one of the following:

4549 -- /NOMINIMAL_RECOMPILATION (D)
4550 -- /MINIMAL_RECOMPILATION
4551 --
4552 -- Specifies that the minimum necessary amount of recompilation

6618 -- /MESSAGES_PROJECT_FILE[=messages-option]
6619 --
6620 -- Specifies the "verbosity" of the parsing of project files.

6626 --
6627 -- HIGH A great number of messages are output, most of them not
6628 -- being useful for the user.
6632 -- /PROJECT_FILE=filename
6633 --
6634 -- Specifies the main project file to be used. The project files rooted
6635 -- at the main project file will be parsed before the invocation of the
6636 -- gnatcheck. The source directories to be searched will be communicated
6637 -- to gnatcheck through logical name ADA_PRJ_INCLUDE_FILE.

6643 --
6644 -- Work quietly, only output warnings and errors.
6648 -- /SUBDIRS=dir
6649 --

6652 -- does not exist, it is created automatically.
6656 -- /NOVERBOSE (D)
6657 -- /VERBOSE
6658 --
6659 -- The version number and copyright notice are output, as well as exact

6723 --
6724 -- Add directories to the project search path.
6728 -- /NOALL_FILES (D)
6729 -- /ALL_FILES
6730 --
6731 -- If this switch is present, FIND and XREF will parse the read-only
6732 -- files found in the library search path. Otherwise, these files will
6733 -- be ignored. This option can be used to protect Gnat sources or your
6734 -- own libraries from being parsed, thus making FIND and XREF much
6735 -- faster, and their output much smaller.
6739 -- /NODERIVED_TYPES (D)
6740 -- /DERIVED_TYPES
6741 --
6742 -- Output the parent type reference for each matching derived types.
6746 -- /EXTERNAL_REFERENCE="name=val"

6764 -- /FULL_PATHNAME
6765 --
6766 -- If this switch is set, the output file names will be preceded by their
6767 -- directory (if the file was found in the search path). If this switch
6768 -- is not set, the directory will not be printed.
6772 -- /NOIGNORE_LOCALS (D)
6773 -- /IGNORE_LOCALS
6774 --
6775 -- If this switch is set, information is output only for library-level
6776 -- entities, ignoring local entities. The use of this switch may
6777 -- accelerate FIND and XREF.
6786 -- /MESSAGES_PROJECT_FILE[=messages-option]
6787 --
6788 -- Specifies the "verbosity" of the parsing of project files.
6789 -- messages-option may be one of the following:

6816 -- as for MAKE.
6820 -- /PROJECT=file
6821 --
6822 -- Specify a project file to use. By default, FIND and XREF will try to
6823 -- locate a project file in the current directory.
6824 --
6825 -- If a project file is either specified or found by the tools, then the
6826 -- content of the source directory and object directory lines are added
6827 -- as if they had been specified respectively by /SOURCE_SEARCH and
6828 -- /OBJECT_SEARCH.
6832 -- /PROJECT_FILE=filename
6833 --
6834 -- Specifies the main project file to be used. The project files rooted
6835 -- at the main project file will be parsed before doing any processing.
