24 -- --
25 ------------------------------------------------------------------------------
27 -- This package contains, for each of the command of the GNAT driver, one
28 -- constant array; each component of this array is a string that defines,
29 -- in coded form as explained below, the conversion of a VMS qualifier of the
30 -- command to the corresponding switch of the GNAT tool corresponding to the
31 -- command.
33 -- This package is used by the GNAT driver to invokes the GNAT tools with the
34 -- switches corresponding to the VMS qualifier and by the Project Manager to
35 -- convert VMS qualifiers in project files to their corresponding switch
36 -- values.
38 -- This package is also an input to the tool that generates the VMS GNAT
39 -- help information automatically.
41 -- NOTE: the format of this package must follow the following rules, so that
42 -- the VMS GNAT help tool works properly:
44 -- - Each command zone (where the eventual qualifiers are declared must
45 -- begin with a boxed comment of the form:
47 -- ---------------------------------
48 -- -- Switches for GNAT <COMMAND> --
49 -- ---------------------------------
51 -- where <COMMAND> is the name of a GNAT command in capital letters, for
52 -- example BIND, COMPILE, XREF, ...
54 -- - each qualifier declaration must be followed either by
55 -- - a comment starting with "-- NODOC", to indicate that there is
56 -- no documentation for this qualifier, or
57 -- - a contiguous sequence of comments that constitute the
58 -- documentation of the qualifier.
60 -- - each command zone ends with the declaration of the contant array
61 -- for the command, of the form:
63 -- <Command>__Switches : aliased constant Switches :=
67 ----------------
68 -- QUALIFIERS --
69 ----------------
71 -- The syntax of a qualifier delaration is as follows:
73 -- SWITCH_STRING ::= "/ command-qualifier-name TRANSLATION"
75 -- TRANSLATION ::=
76 -- DIRECT_TRANSLATION
77 -- | DIRECTORIES_TRANSLATION
78 -- | FILE_TRANSLATION
79 -- | NO_SPACE_FILE_TRANSL
80 -- | NUMERIC_TRANSLATION
81 -- | STRING_TRANSLATION
82 -- | OPTIONS_TRANSLATION
83 -- | COMMANDS_TRANSLATION
84 -- | ALPHANUMPLUS_TRANSLATION
85 -- | OTHER_TRANSLATION
87 -- DIRECT_TRANSLATION ::= space UNIX_SWITCHES
88 -- DIRECTORIES_TRANSLATION ::= =* UNIX_SWITCH *
89 -- DIRECTORY_TRANSLATION ::= =% UNIX_SWITCH %
90 -- FILE_TRANSLATION ::= =@ UNIX_SWITCH @
91 -- NO_SPACE_FILE_TRANSL ::= =< UNIX_SWITCH >
92 -- NUMERIC_TRANSLATION ::= =# UNIX_SWITCH # | # number #
93 -- STRING_TRANSLATION ::= =" UNIX_SWITCH "
94 -- OPTIONS_TRANSLATION ::= =OPTION {space OPTION}
95 -- COMMANDS_TRANSLATION ::= =? ARGS space command-name
96 -- ALPHANUMPLUS_TRANSLATION ::= =| UNIX_SWITCH |
98 -- UNIX_SWITCHES ::= UNIX_SWITCH {, UNIX_SWITCH}
100 -- UNIX_SWITCH ::= unix-switch-string | !unix-switch-string | `string'
102 -- OPTION ::= option-name space UNIX_SWITCHES
104 -- ARGS ::= -cargs | -bargs | -largs
106 -- Here command-qual is the name of the switch recognized by the GNATCmd.
107 -- This is always given in upper case in the templates, although in the
108 -- actual commands, either upper or lower case is allowed.
110 -- The unix-switch-string always starts with a minus, and has no commas
111 -- or spaces in it. Case is significant in the unix switch string. If a
112 -- unix switch string is preceded by the not sign (!) it means that the
113 -- effect of the corresponding command qualifer is to remove any previous
114 -- occurrence of the given switch in the command line.
116 -- The DIRECTORIES_TRANSLATION format is used where a list of directories
117 -- is given. This possible corresponding formats recognized by GNATCmd are
118 -- as shown by the following example for the case of PATH
120 -- PATH=direc
121 -- PATH=(direc,direc,direc,direc)
123 -- When more than one directory is present for the DIRECTORIES case, then
124 -- multiple instances of the corresponding unix switch are generated,
125 -- with the file name being substituted for the occurrence of *.
127 -- The FILE_TRANSLATION format is similar except that only a single
128 -- file is allowed, not a list of files, and only one unix switch is
129 -- generated as a result.
131 -- the NO_SPACE_FILE_TRANSL is similar to FILE_TRANSLATION, except that
132 -- no space is inserted between the switch and the file name.
134 -- The NUMERIC_TRANSLATION format is similar to the FILE_TRANSLATION case
135 -- except that the parameter is a decimal integer in the range 0 to 999.
137 -- For the OPTIONS_TRANSLATION case, GNATCmd similarly permits one or
138 -- more options to appear (although only in some cases does the use of
139 -- multiple options make logical sense). For example, taking the
140 -- case of ERRORS for GCC, the following are all allowed:
142 -- /ERRORS=BRIEF
143 -- /ERRORS=(FULL,VERBOSE)
144 -- /ERRORS=(BRIEF IMMEDIATE)
146 -- If no option is provided (e.g. just /ERRORS is written), then the
147 -- first option in the list is the default option. For /ERRORS this
148 -- is NORMAL, so /ERRORS with no option is equivalent to /ERRORS=NORMAL.
150 -- The COMMANDS_TRANSLATION case is only used for gnatmake, to correspond
151 -- to the use of -cargs, -bargs and -largs (the ARGS string as indicated
152 -- is one of these three possibilities). The name given by COMMAND is the
153 -- corresponding command name to be used to interprete the switches to be
154 -- passed on. Switches of this type set modes, e.g. /COMPILER_QUALIFIERS
155 -- sets the mode so that all subsequent switches, up to another switch
156 -- with COMMANDS_TRANSLATION apply to the corresponding commands issued
157 -- by the make utility. For example
159 -- /COMPILER_QUALIFIERS /LIST /BINDER_QUALIFIERS /MAIN
160 -- /COMPILER_QUALIFIERS /NOLIST /COMPILE_CHECKS=SYNTAX
162 -- Clearly these switches must come at the end of the list of switches
163 -- since all subsequent switches apply to an issued command.
165 -- For the DIRECT_TRANSLATION case, an implicit additional qualifier
166 -- declaration is created by prepending NO to the name of the qualifer,
167 -- and then inverting the sense of the UNIX_SWITCHES string. For example,
168 -- given the qualifier definition:
170 -- "/LIST -gnatl"
172 -- An implicit qualifier definition is created:
174 -- "/NOLIST !-gnatl"
176 -- In the case where, a ! is already present, inverting the sense of the
177 -- switch means removing it.
180 -- A synonym to shorten the table
183 -- String pointer type used throughout
186 -- Type used for array of swtiches

368 --
369 -- Output full names of all the object files that must be linker to

378 -- Output chosen elaboration order. The output is written to SYS$OUTPUT.
382 -- /OUTPUT=filename
383 --
384 -- File name to use for the program containing the elaboration code.
388 -- /NOOUTPUT
389 --
390 -- Check only. Do not generate the binder output file.
391 --
392 -- In this mode the binder performs all error checks but does not generate

397 -- /PESSIMISTIC_ELABORATION
398 --
399 -- Causes the binder to choose a "pessimistic" elaboration order, i.e. one
400 -- which is most likely to cause elaboration order problems. This can be
401 -- useful in testing portable code to make sure that there are no missing
402 -- elaborate pragmas.
406 -- /PROJECT_FILE=filename
407 --
408 -- Specifies the main project file to be used. The project files rooted
409 -- at the main project file will be parsed before the invocation of the
410 -- binder. The source and object directories to be searched will be
411 -- communicated to the binder through logical names ADA_PRJ_INCLUDE_FILE
412 -- and ADA_PRJ_OBJECTS_FILE.
421 -- /READ_SOURCES[=(keyword[,...])]
422 -- /NOREAD_SOURCES
423 --
424 -- The following keyword are accepted:
425 --
426 -- ALL (D) Require source files to be present. In this mode, the
427 -- binder insists on being able to locate all source files
428 -- that are referenced and checks their consistency. In
429 -- normal mode, if a source file cannot be located it is
430 -- simply ignored. If you specify the ALL keyword, a
431 -- missing source file is an error.
432 --
433 -- NONE Exclude source files. In this mode, the binder only
434 -- checks that ALI files are consistent with one another.
435 -- source files are not accessed. The binder runs faster
436 -- in this mode, and there is still a guarantee that the
437 -- resulting program is self-consistent.
438 --
439 -- If a source file has been edited since it was last
440 -- compiled and you specify the NONE keyword, the binder
441 -- will not detect that the object file is out of date
442 -- with the source file.
443 --
444 -- This is the same as specifying /NOREAD_SOURCES.
445 --
446 -- AVAILABLE Check that object files are consistent with one
447 -- another and are consistent with any source files that
448 -- can be located.
452 -- NODOC (see /READ_SOURCES)
456 -- /RENAME_MAIN=xxx
457 --
458 -- Renames the generated main program from main to xxx.
459 -- This is useful in the case of some cross-building environments, where
460 -- the actual main program is separate from the one generated
461 -- by GNAT BIND.
470 -- /REPORT_ERRORS[=(keyword[,...])]
471 -- VERBOSE (D)
472 -- BRIEF
473 -- DEFAULT
474 -- /NOREPORT_ERRORS
475 --
476 -- With the DEFAULT keyword (which is not the default when the binder is
477 -- run from GNAT BIND) or the /NOREPORT_ERRORS qualifier, brief error
478 -- messages are generated to SYS$ERROR. If the VERBOSE keyword is
479 -- present, a header is written to SYS$OUTPUT and any error messages are
480 -- directed to SYS$OUTPUT All that is written to SYS$ERROR is a brief
481 -- summary message.
482 --
483 -- If the BRIEF keyword is specified, the binder will generate brief error
484 -- messages to SYS$ERROR even if verbose mode is specified. This is
485 -- relevant only when used together with the VERBOSE keyword or /VERBOSE
486 -- qualifier.
490 -- NODOC (see /REPORT_ERRORS)
494 -- /NORESTRICTION_LIST (D)
495 -- /RESTRICTION_LIST
496 --
497 -- Generate list of pragma Rerstrictions that could be applied to the
498 -- current unit. This is useful for code audit purposes, and also may be
499 -- used to improve code generation in some cases.
506 -- /RETURN_CODES=POSIX (D)
507 -- /RETURN_CODES=VMS
508 --
509 -- Specifies the style of default exit code returned. Must be used in
510 -- conjunction with and match the Link qualifer with same name.
511 --
512 -- POSIX (D) Return Posix success (0) by default.
513 --
514 -- VMS Return VMS success (1) by default.
518 -- /RUNTIME_SYSTEM=xxx
519 --
520 -- Binds against an alternate runtime system named xxx or RTS-xxx.
524 -- /SEARCH=(directory[,...])
525 --
526 -- When looking for source or object files also look in directories
527 -- specified.
528 --
529 -- This is the same as specifying both /LIBRARY_SEARCH and /SOURCE_SEARCH
530 -- for a directory.
534 -- /SHARED
535 -- /NOSHARED
536 --
537 -- Link against a shared GNAT run time when available.
541 -- /TIME_SLICE=nnn
542 --
543 -- Set the time slice value to nnn milliseconds. A value of zero means no
544 -- time slicing and also indicates to the tasking run time to match as
545 -- close as possible to the annex D requirements of the RM.
549 -- /SOURCE_SEARCH=(directory[,...])
550 --
551 -- When looking for source files also look in directories specified.
555 -- /STATIC
556 -- /NOSTATIC
557 --
558 -- Link against a static GNAT run time.
562 -- /STORE_TRACEBACKS (D)
563 -- /NOSTORE_TRACEBACKS
564 --
565 -- Store tracebacks in exception occurrences.
566 -- This is the default on VMS, with the zero-cost exception mechanism.
567 -- This qualifier has no impact, except when using the setjmp/longjmp
568 -- exception mechanism, with the GNAT COMPILE qualifier /LONGJMP_SETJMP.
572 -- /TIME_STAMP_CHECK (D)
573 --
574 -- Time stamp errors will be treated as errors.
575 --
576 -- /NOTIME_STAMP_CHECK
577 --
578 -- Ignore time stamp errors. Any time stamp error messages are treated as
579 -- warning messages. This switch essentially disconnects the normal
580 -- consistency checking, and the resulting program may have undefined
581 -- semantics if inconsistent units are present.
582 --
583 -- This means that /NOTIME_STAMP_CHECK should be used only in unusual
584 -- situations, with extreme care.
588 -- /VERBOSE (D)
589 -- /NOVERBOSE
590 --
591 -- Equivalent to /REPORT_ERRORS=VERBOSE.
600 -- /WARNINGS[=(keyword[,...])]
601 -- /NOWARNINGS
602 --
603 -- The following keywords are supported:
604 --
605 -- NORMAL (D) Print warning messages and treat them as warning.
606 -- SUPPRESS Suppress all warning messages (same as /NOWARNINGS).
607 -- ERROR Treat any warning messages as fatal errors
611 -- NODOC (see /WARNINGS)
615 -- /NOZERO_MAIN (D)
616 -- /ZERO_MAIN
617 --
618 -- Normally the binder checks that the unit name given on the command line
619 -- corresponds to a suitable main subprogram. When /ZERO_MAIN is used,
620 -- a list of ALI files can be given, and the execution of the program
621 -- consists of elaboration of these units in an appropriate order.

1005 --
1006 -- OVERFLOW Enables overflow checking for integer operations and
1007 -- checks for access before elaboration on subprogram

1451 -- Set maximum line length.
1452 -- The length of lines must not exceed the given value nnn.
1456 -- /NOLIST (D)
1457 -- /LIST
1458 --
1459 -- Cause a full listing of the file to be generated.
1463 -- /MAPPING_FILE=file_name
1464 --
1465 -- Use mapping file file_name
1466 --
1467 -- A mapping file is a way to communicate to the compiler two mappings:
1468 -- from unit names to file names (without any directory information) and
1469 -- from file names to path names (with full directory information).
1470 -- These mappings are used by the compiler to short-circuit the path
1471 -- search.
1472 --
1473 -- The use of mapping files is not required for correct operation of the
1474 -- compiler, but mapping files can improve efficiency, particularly when
1475 -- sources are read over a slow network connection. In normal operation,
1476 -- you need not be concerned with the format or use of mapping files,
1477 -- and /MAPPING_FILE is not a qualifier that you would use explicitly.
1478 -- It is intended only for use by automatic tools such as GNAT MAKE
1479 -- running under the project file facility. The description here of the
1480 -- format of mapping files is provided for completeness and for possible
1481 -- use by other tools.
1482 --
1483 -- A mapping file is a sequence of sets of three lines. In each set, the
1484 -- first line is the unit name, in lower case, with "%s" appended for
1485 -- specifications and "%b" appended for bodies; the second line is the
1486 -- file name; and the third line is the path name.
1487 --
1488 -- Example:
1489 --
1490 -- main%b
1491 -- main.2_ada
1492 -- /gnat/project1/sources/main.2_ada
1493 --
1494 -- When qualifier ?MAPPING_FILE is specified, the compiler will create in
1495 -- memory the two mappings from the specified file. If there is any
1496 -- problem (non existent file, truncated file or duplicate entries),
1497 -- no mapping will be created.
1498 --
1499 -- Several /MAPPING_FILE qualifiers may be specified; however, only the
1500 -- last one on the command line will be taken into account.
1501 --
1502 -- When using a project file, GNAT MAKE creates a temporary mapping file
1503 -- and communicates it to the compiler using this switch.
1512 -- /MESSAGES_PROJECT_FILE[=messages-option]
1513 --
1514 -- Specifies the "verbosity" of the parsing of project files.
1515 -- messages-option may be one of the following:
1516 --
1517 -- DEFAULT (D) No messages are output if there is no error or warning.
1518 --
1519 -- MEDIUM A small number of messages are output.
1520 --
1521 -- HIGH A great number of messages are output, most of them not
1522 -- being useful for the user.
1526 -- /MAX_NESTING=nnn
1527 --
1528 -- Set maximum level of nesting of constructs (including subprograms,
1529 -- loops, blocks, packages, and conditionals).
1530 -- The level of nesting must not exceed the given value nnn.
1531 -- A value of zero disable this style check (not enabled by default).
1535 -- /NO_GNAT_ADC
1536 --
1537 -- Cause the compiler to ignore any configuration pragmas file GNAT.ADC
1538 -- in the default directory. Implied by qualifier /PROJECT_FILE.
1539 -- Often used in conjunction with qualifier /CONFIGURATION_PRAGMAS_FILE.
1543 -- /NOLOAD
1544 --
1545 -- Cause the compiler to operate in semantic check mode with full
1546 -- checking for all illegalities specified in the reference manual, but
1547 -- without generation of any source code (no object or ALI file
1548 -- generated).
1549 --
1550 -- Since dependent files must be accessed, you must follow the GNAT
1551 -- semantic restrictions on file structuring to operate in this mode:
1552 --
1553 -- o The needed source files must be accessible.
1554 -- o Each file must contain only one compilation unit.
1555 -- o The file name and unit name must match.
1556 --
1557 -- The output consists of error messages as appropriate. No object file
1558 -- or ALI file is generated. The checking corresponds exactly to the
1559 -- notion of legality in the Ada reference manual.
1560 --
1561 -- Any unit can be compiled in semantics-checking-only mode, including
1562 -- units that would not normally be compiled (generic library units,
1563 -- subunits, and specifications where a separate body is present).
1567 -- /NOSTD_INCLUDES
1568 --
1569 -- Do not look in the default directory for source files of the runtime.
1573 -- /NOSTD_LIBRARIES
1574 --
1575 -- Do not look for library files in the system default directory.
1592 -- /NOOPTIMIZE (D)
1593 -- /OPTIMIZE[=(keyword[,...])]
1594 --
1595 -- Selects the level of optimization for your program. The supported
1596 -- keywords are as follows:
1597 --
1598 -- ALL (D) Perform most optimizations, including those that
1599 -- may be expensive.
1600 --
1601 -- NONE Do not do any optimizations. Same as /NOOPTIMIZE.
1602 --
1603 -- SOME Perform some optimizations, but omit ones that
1604 -- are costly in compilation time.
1605 --
1606 -- DEVELOPMENT Same as SOME.
1607 --
1608 -- INLINING Full optimization, and also attempt automatic inlining
1609 -- of small subprograms within a unit
1610 --
1611 -- UNROLL_LOOPS Try to unroll loops. This keyword may be specified
1612 -- with any keyword above other than NONE. Loop
1613 -- unrolling usually, but not always, improves the
1614 -- performance of programs.
1615 --
1616 -- NO_STRICT_ALIASING
1617 -- Suppress aliasing analysis. When optimization is
1618 -- enabled (ALL or SOME above), the compiler assumes
1619 -- that pointers do in fact point to legitimate values
1620 -- of the pointer type (allocated from the proper pool).
1621 -- If this assumption is violated, e.g. by the use of
1622 -- unchecked conversion, then it may be necessary to
1623 -- suppress this assumption using this keyword (which
1624 -- may be specified only in conjunction with any
1625 -- keyword above, other than NONE).
1629 -- NODOC (see /OPTIMIZE)
1633 -- /NOPOLLING (D)
1634 -- /POLLING
1635 --
1636 -- Enable polling. See the description of pragma Polling in the GNAT
1637 -- Reference Manual for full details.
1641 -- /PROJECT_FILE=filename
1642 --
1643 -- Specifies the main project file to be used. The project files rooted
1644 -- at the main project file will be parsed before the invocation of the
1645 -- compiler. The source and object directories to be searched will be
1646 -- communicated to the compiler through logical names
1647 -- ADA_PRJ_INCLUDE_FILE and ADA_PRJ_OBJECTS_FILE.
1651 -- /PRINT_STANDARD
1652 --
1653 -- cause the compiler to output a representation of package Standard
1654 -- in a form very close to standard Ada. It is not quite possible to
1655 -- do this and remain entirely Standard (since new numeric base types
1656 -- cannot be created in standard Ada), but the output is easily
1657 -- readable to any Ada programmer, and is useful to determine the
1658 -- characteristics of target dependent types in package Standard.
1671 -- /NOREPORT_ERRORS (D)
1672 -- /REPORT_ERRORS[=(keyword[,...])]
1673 --
1674 -- Change the way errors are reported. The following keywords are
1675 -- supported:
1676 --
1677 -- VERBOSE (D) Verbose mode. Full error output with source lines
1678 -- to SYS$OUTPUT.
1679 --
1680 -- BRIEF Generate the brief format error messages to
1681 -- SYS$OUTPUT as well as the verbose format message or
1682 -- full listing.
1683 --
1684 -- FULL Normally, the compiler suppresses error messages that
1685 -- are likely to be redundant. This keyword causes all
1686 -- error messages to be generated. One particular effect
1687 -- is for the case of references to undefined variables.
1688 -- If a given variable is referenced several times, the
1689 -- normal format of messages produces one error. With
1690 -- FULL, each undefined reference produces a separate
1691 -- error message.
1692 --
1693 -- IMMEDIATE Normally, the compiler saves up error messages and
1694 -- generates them at the end of compilation in proper
1695 -- sequence. This keyword causes error messages to be
1696 -- generated as soon as they are detected. The use of
1697 -- IMMEDIATE usually causes error messages to be
1698 -- generated out of sequence. Use it when the compiler
1699 -- blows up due to an internal error. In this case, the
1700 -- error messages may be lost. Sometimes blowups are
1701 -- the result of mishandled error messages, so you may
1702 -- want to run with this keyword to determine whether
1703 -- any error messages were generated.
1704 --
1705 -- DEFAULT Turn off VERBOSE and BRIEF. Same as /NOREPORT_ERRORS.
1709 -- NODOC (see /REPORT_ERRORS)
1728 -- /NOREPRESENTATION_INFO (D)
1729 -- /REPRESENTATION_INFO[=(keyword[,...])]
1730 --
1731 -- This qualifier controls output from the compiler of a listing showing
1732 -- representation information for declared types and objects.
1733 --
1734 -- ARRAYS (D) Size and alignment information is listed for
1735 -- declared array and record types.
1736 --
1737 -- ARRAYS_FILE Similar to ARRAYS, but the output is to a file
1738 -- with the name 'file_rep' where 'file' is the name
1739 -- of the corresponding source file.
1740 --
1741 -- NONE no information is output (equivalent to omitting
1742 -- the /REPRESENTATION_INFO qualifiers).
1743 --
1744 -- OBJECTS Size and alignment information is listed for all
1745 -- declared types and objects.
1746 --
1747 -- OBJECTS_FILE Similar to OBJECTS, but the output is to a file
1748 -- with the name 'file_rep' where 'file' is the name
1749 -- of the corresponding source file.
1750 --
1751 -- SYMBOLIC Symbolic expression information for values that
1752 -- are computed at run time for variant records.
1753 --
1754 -- SYMBOLIC_FILE Similar to SYMBOLIC, but the output is to a file
1755 -- with the name 'file_rep' where 'file' is the name
1756 -- of the corresponding source file.
1757 --
1758 -- DEFAULT Equivalent to ARRAYS.
1762 -- NODOC (see /REPRESENTATION_INFO)
1766 -- /RUNTIME_SYSTEM=xxx
1767 --
1768 -- Build against an alternate runtime system named xxx or RTS-xxx.
1772 -- /SEARCH=(directory[,...])
1773 --
1774 -- When looking for source files also look in directories specified.
1839 -- /NOSTYLE_CHECKS (D)
1840 -- /STYLE_CHECKS[=(keyword,[...])]
1841 --
1842 -- Normally, GNAT permits any code layout consistent with the reference
1843 -- manual requirements. This qualifier imposes style checking on the
1844 -- input source code. The following keywords are supported:
1845 --
1846 -- ALL_BUILTIN (D) Equivalent to the following list of options:
1847 -- 3, ATTRIBUTE, BLANKS, COMMENTS, END, VTABS,
1848 -- HTABS, IF_THEN, KEYWORD, LAYOUT, LINE_LENGTH,
1849 -- PRAGMA, REFERENCES, SPECS, TOKEN.
1850 --
1851 -- 1 .. 9 Specify indentation level from 1 to 9.
1852 -- The general style of required indentation is as
1853 -- specified by the examples in the Ada Reference
1854 -- Manual. Full line comments must be aligned with
1855 -- the -- starting on a column that is a multiple
1856 -- of the alignment level.
1857 --
1858 -- ATTRIBUTE Check attribute casing.
1859 -- Attribute names, including the case of keywords
1860 -- such as digits used as attributes names,
1861 -- must be written in mixed case, that is,
1862 -- the initial letter and any letter following an
1863 -- underscore must be uppercase.
1864 -- All other letters must be lowercase.
1865 --
1866 -- BLANKS Blanks not allowed at statement end.
1867 -- Trailing blanks are not allowed at the end of
1868 -- statements. The purpose of this rule, together
1869 -- with option HTABS (no horizontal tabs), is to
1870 -- enforce a canonical format for the use of
1871 -- blanks to separate source tokens.
1872 --
1873 -- COMMENTS Check comments.
1874 -- Comments must meet the following set of rules:
1875 --
1876 -- * The "--" that starts the column must either
1877 -- start in column one, or else at least one
1878 -- blank must precede this sequence.
1879 --
1880 -- * Comments that follow other tokens on a line
1881 -- must have at least one blank following the
1882 -- "--" at the start of the comment.
1883 --
1884 -- * Full line comments must have two blanks
1885 -- following the "--" that starts the comment,
1886 -- with the following exceptions.
1887 --
1888 -- * A line consisting only of the "--"
1889 -- characters, possibly preceded by blanks is
1890 -- permitted.
1891 --
1892 -- * A comment starting with "--x" where x is
1893 -- a special character is permitted. This
1894 -- allows proper processing of the output
1895 -- generated by specialized tools including
1896 -- gnatprep (where --! is used) and the SPARK
1897 -- annnotation language (where --# is used).
1898 -- For the purposes of this rule, a special
1899 -- character is defined as being in one of the
1900 -- ASCII ranges 16#21#..16#2F# or
1901 -- 16#3A#..16#3F#.
1902 --
1903 -- * A line consisting entirely of minus signs,
1904 -- possibly preceded by blanks, is permitted.
1905 -- This allows the construction of box
1906 -- comments where lines of minus signs are
1907 -- used to form the top and bottom of the box.
1908 --
1909 -- * If a comment starts and ends with "--" is
1910 -- permitted as long as at least one blank
1911 -- follows the initial "--". Together with
1912 -- the preceding rule, this allows the
1913 -- construction of box comments, as shown in
1914 -- the following example:
1915 --
1916 -- ---------------------------
1917 -- -- This is a box comment --
1918 -- ---------------------------
1919 --
1920 -- END Check end/exit labels.
1921 -- Optional labels on end statements ending
1922 -- subprograms and on exit statements exiting
1923 -- named loops, are required to be present.
1924 --
1925 -- GNAT Enforces a set of style conventions that
1926 -- correspond to the style used in the GNAT
1927 -- source code. All compiler units are always
1928 -- compile with this keyword specified.
1929 --
1930 -- You can find the full documentation for the
1931 -- style conventions imposed by this keyword
1932 -- in the body of the package "Style" in the
1933 -- compiler sources.
1934 --
1935 -- You should not normally use this keyword.
1936 -- However, you MUST use it for compiling any
1937 -- language-defined unit, or for adding children
1938 -- to any language-defined unit other than
1939 -- "Standard".
1940 --
1941 -- HTABS No horizontal tabs.
1942 -- Horizontal tab characters are not permitted in
1943 -- the source text. Together with the BLANKS
1944 -- (no blanks at end of line) option, this
1945 -- enforces a canonical form for the use of blanks
1946 -- to separate source tokens.
1947 --
1948 -- IF_THEN Check if-then layout.
1949 -- The keyword then must appear either on the
1950 -- same line as the corresponding if, or on a line
1951 -- on its own, lined up under the if with at least
1952 -- one non-blank line in between containing all or
1953 -- part of the condition to be tested.
1954 --
1955 -- KEYWORD Check keyword casing.
1956 -- All keywords must be in lower case (with the
1957 -- exception of keywords such as digits used as
1958 -- attribute names to which this check does not
1959 -- apply).
1960 --
1961 -- LAYOUT Check layout.
1962 -- Layout of statement and declaration constructs
1963 -- must follow the recommendations in the Ada
1964 -- Reference Manual, as indicated by the form of
1965 -- the syntax rules. For example an else keyword
1966 -- must be lined up with the corresponding if
1967 -- keyword.
1968 --
1969 -- There are two respects in which the style rule
1970 -- enforced by this check option are more liberal
1971 -- than those in the Ada Reference Manual.
1972 -- First in the case of record declarations,
1973 -- it is permissible to put the record keyword on
1974 -- the same line as the type keyword, and then
1975 -- the end in end record must line up under type.
1976 -- For example, either of the following two
1977 -- layouts is acceptable:
1978 --
1979 -- type q is record
1980 -- a : integer;
1981 -- b : integer;
1982 -- end record;
1983 --
1984 -- type q is
1985 -- record
1986 -- a : integer;
1987 -- b : integer;
1988 -- end record;
1989 --
1990 -- Second, in the case of a block statement,
1991 -- a permitted alternative is to put the block
1992 -- label on the same line as the declare or begin
1993 -- keyword, and then line the end keyword up under
1994 -- the block label. For example both the following
1995 -- are permitted:
1996 --
1997 --
1998 --
1999 -- Block : declare
2000 -- A : Integer := 3;
2001 -- begin
2002 -- Proc (A, A);
2003 -- end Block;
2004 --
2005 -- Block :
2006 -- declare
2007 -- A : Integer := 3;
2008 -- begin
2009 -- Proc (A, A);
2010 -- end Block;
2011 --
2012 -- The same alternative format is allowed for
2013 -- loops. For example, both of the following are
2014 -- permitted:
2015 --
2016 --
2017 --
2018 -- Clear : while J < 10 loop
2019 -- A (J) := 0;
2020 -- end loop Clear;
2021 --
2022 -- Clear :
2023 -- while J < 10 loop
2024 -- A (J) := 0;
2025 -- end loop Clear;
2026 --
2027 --
2028 --
2029 -- LINE_LENGTH Check maximum line length.
2030 -- The length of source lines must not exceed 79
2031 -- characters, including any trailing blanks
2032 -- The value of 79 allows convenient display on
2033 -- an 80 character wide device or window, allowing
2034 -- for possible special treatment of 80 character
2035 -- lines.
2036 --
2037 -- NONE Clear any previously set style checks.
2038 --
2039 -- ORDERED_SUBPROGRAMS Check order of subprogram bodies.
2040 -- All subprogram bodies in a given scope (e.g.
2041 -- a package body) must be in alphabetical order.
2042 -- The ordering rule uses normal Ada rules for
2043 -- comparing strings, ignoring casing of letters,
2044 -- except that if there is a trailing numeric
2045 -- suffix, then the value of this suffix is used
2046 -- in the ordering (e.g. Junk2 comes before
2047 -- Junk10).
2048 --
2049 -- NONE The default behavior. Same as /NOSTYLE_CHECKS.
2050 --
2051 -- PRAGMA Check pragma casing.
2052 -- Pragma names must be written in mixed case,
2053 -- that is, the initial letter and any letter
2054 -- following an underscore must be uppercase.
2055 -- All other letters must be lowercase.
2056 --
2057 -- REFERENCES Check references.
2058 -- All identifier references must be cased in the
2059 -- same way as the corresponding declaration.
2060 -- No specific casing style is imposed on
2061 -- identifiers. The only requirement is for
2062 -- consistency of references with declarations.
2063 --
2064 -- RM_COLUMN_LAYOUT Enforce the layout conventions suggested by
2065 -- the examples and syntax rules of the Ada
2066 -- Language Reference Manual. For example, an
2067 -- "else" must line up with an "if" and code in
2068 -- the "then" and "else" parts must be indented.
2069 -- The compiler considers violations of the
2070 -- layout rules a syntax error if you specify
2071 -- this keyword.
2072 --
2073 -- SPECS Check separate specs.
2074 -- Separate declarations ("specs") are required
2075 -- for subprograms (a body is not allowed to serve
2076 -- as its own declaration). The only exception is
2077 -- that parameterless library level procedures are
2078 -- not required to have a separate declaration.
2079 -- This exception covers the most frequent form of
2080 -- main program procedures.
2081 --
2082 -- STANDARD_CASING Check casing of entities in Standard.
2083 -- Any identifier from Standard must be cased to
2084 -- match the presentation in the Ada Reference
2085 -- Manual (for example, Integer and ASCII.NUL).
2086 --
2087 -- TOKEN Check token spacing.
2088 -- The following token spacing rules are enforced:
2089 --
2090 -- * The keywords abs and not must be followed
2091 -- by a space.
2092 --
2093 -- * The token => must be surrounded by spaces.
2094 --
2095 -- * The token <> must be preceded by a space or
2096 -- a left parenthesis.
2097 --
2098 -- * Binary operators other than ** must be
2099 -- surrounded by spaces. There is no
2100 -- restriction on the layout of the ** binary
2101 -- operator.
2102 --
2103 -- * Colon must be surrounded by spaces.
2104 --
2105 -- * Colon-equal (assignment) must be surrounded
2106 -- by spaces.
2107 --
2108 -- * Comma must be the first non-blank character
2109 -- on the line, or be immediately preceded by
2110 -- a non-blank character, and must be followed
2111 -- by a space.
2112 --
2113 -- * If the token preceding a left paren ends
2114 -- with a letter or digit, then a space must
2115 -- separate the two tokens.
2116 --
2117 -- * A right parenthesis must either be the
2118 -- first non-blank character on a line, or it
2119 -- must be preceded by a non-blank character.
2120 --
2121 -- * A semicolon must not be preceded by
2122 -- a space, and must not be followed by
2123 -- a non-blank character.
2124 --
2125 -- * A unary plus or minus may not be followed
2126 -- by a space.
2127 --
2128 -- * A vertical bar must be surrounded by
2129 -- spaces.
2130 --
2131 -- In the above rules, appearing in column one is
2132 -- always permitted, that is, counts as meeting
2133 -- either a requirement for a required preceding
2134 -- space, or as meeting a requirement for no
2135 -- preceding space.
2136 --
2137 -- Appearing at the end of a line is also always
2138 -- permitted, that is, counts as meeting either
2139 -- a requirement for a following space,
2140 -- or as meeting a requirement for no following
2141 -- space.
2142 --
2143 -- VTABS No form feeds or vertical tabs.
2144 -- Form feeds or vertical tab characters are not
2145 -- permitted in the source text.
2149 -- NODOC (see /STYLE_CHECKS)
2153 -- /SYMBOL_PREPROCESSING="symbol=value"
2154 --
2155 -- Define or redefine a preprocessing symbol, associated with value.
2156 -- If "=value" is not specified, then the value of the symbol is True.
2157 -- A symbol is an identifier, following normal Ada (case-insensitive)
2158 -- rules for its syntax, and value is any sequence (including an empty
2159 -- sequence) of characters from the set (letters, digits, period,
2160 -- underline). Ada reserved words may be used as symbols, with the
2161 -- exceptions of "if", "else", "elsif", "end", "and", "or" and "then".
2162 --
2163 -- A symbol declared with this qualifier on the command line replaces
2164 -- a symbol with the same name either in a definition file or specified
2165 -- with a switch -D in the preprocessor data file.
2166 --
2167 -- This qualifier is similar to qualifier /ASSOCIATE of
2168 -- GNAT PREPROCESSING.
2172 -- /NOSYNTAX_ONLY (D)
2173 -- /SYNTAX_ONLY
2174 --
2175 -- Run GNAT in syntax checking only mode. You can check a series of
2176 -- files in a single command, and can use wild cards to specify such a
2177 -- group of files.
2178 --
2179 -- You may use other qualifiers in conjunction with this qualifier. In
2180 -- particular, /LIST and /REPORT_ERRORS=VERBOSE are useful to control the
2181 -- format of any generated error messages.
2182 --
2183 -- The output is simply the error messages, if any. No object file or ALI
2184 -- file is generated by a syntax-only compilation. Also, no units other
2185 -- than the one specified are accessed. For example, if a unit "X" with's
2186 -- a unit "Y", compiling unit "X" in syntax check only mode does not
2187 -- access the source file containing unit "Y".
2188 --
2189 -- Normally, GNAT allows only a single unit in a source file. However,
2190 -- this restriction does not apply in syntax-check-only mode, and it is
2191 -- possible to check a file containing multiple compilation units
2192 -- concatenated together. This is primarily used by the GNAT CHOP
2193 -- command.

2198 --
2199 -- All compiler tables start at nnn times usual starting size.
2203 -- /TRACE_UNITS
2204 -- /NOTRACE_UNITS
2205 --
2206 -- This switch that does for the frontend what /VERBOSE does for the

2208 -- unit or nested unit, as it is being analyzed.
2212 -- /TREE_OUTPUT
2213 -- /NOTREE_OUTPUT
2214 --
2215 -- Cause GNAT to write the internal tree for a unit to a file (with the
2216 -- filetype ATB for a body or ATS for a spec). This is not normally
2217 -- required, but is used by separate analysis tools. Typically these
2218 -- tools do the necessary compilations automatically, so you should never
2219 -- have to specify this switch in normal operation.
2223 -- /TRY_SEMANTICS
2224 -- /NOTRY_SEMANTICS
2225 --
2226 -- In normal operation mode the compiler first parses the program and
2227 -- determines if there are any syntax errors. If there are, appropriate
2228 -- error messages are generated and compilation is immediately
2229 -- terminated. This qualifier tells GNAT to continue with semantic
2230 -- analysis even if syntax errors have been found. This may enable the
2231 -- detection of more errors in a single run. On the other hand, the
2232 -- semantic analyzer is more likely to encounter some internal fatal
2233 -- error when given a syntactically invalid tree.
2237 -- /NOUNITS_LIST (D)
2238 -- /UNITS_LIST

2305 --
2306 -- Control level of validity checking.
2307 --
2308 -- DEFAULT (D) In this mode checks are made to prevent
2309 -- erroneous behavior in accordance with the RM.
2310 -- Notably extra checks may be needed for case
2311 -- statements and subscripted array assignments.
2312 --
2313 -- NONE No special checks for invalid values are
2314 -- performed. This means that references to
2315 -- uninitialized variables can cause erroneous
2316 -- behavior from constructs like case statements
2317 -- and subscripted array assignments. In this
2318 -- mode, invalid values can lead to erroneous
2319 -- behavior.
2320 --
2321 -- FULL Every assignment is checked for validity, so
2322 -- that it is impossible to assign invalid values.
2323 -- The RM specifically allows such assignments,
2324 -- but in this mode, invalid values can never be
2325 -- assigned, and an attempt to perform such an
2326 -- assignment immediately raises Constraint_Error.
2327 -- This behavior is allowed (but not required) by
2328 -- the RM. This mode is intended as a debugging aid,
2329 -- and may be useful in helping to track down

2452 --
2453 -- In addition to error messages, corresponding to illegalities as

2459 --
2460 -- You may specify the following keywords to change this behavior:
2461 --
2462 -- DEFAULT (D) The default behavior above.
2463 --
2464 -- ALL Activate all optional warnings.

2520 --
2521 -- HIDING Activate warnings on hiding declarations.
2522 -- A declaration is considered hiding if it is
2523 -- for a non-overloadable entity, and it declares

2553 --
2554 -- NOINEFFECTIVE_INLINE Suppress warnings on ineffective pragma Inlines
2555 -- Suppresses warnings on ineffective pragma

2559 --
2560 -- MODIFIED_UNREF Activates warnings for variables that are
2561 -- assigned (using an initialization value or with
2562 -- one or more assignment statements) but whose
2563 -- value is never read. The warning is suppressed
2564 -- for volatile variables and also for variables

2571 --
2572 -- NORMAL Sets normal warning mode, in which enabled
2573 -- warnings are issued and treated as warnings
2574 -- rather than errors. This is the default mode.
2575 -- It can be used to cancel the effect of an

2580 --
2581 -- OBSOLESCENT Activates warnings for calls to subprograms
2582 -- marked with pragma Obsolescent and for use of
2583 -- features in Annex J of the Ada Reference
2584 -- Manual. In the case of Annex J, not all
2585 -- features are flagged. In particular use of the
2586 -- renamed packages (like Text_IO), use of package
2587 -- ASCII and use of the attribute 'Constrained are
2588 -- not flagged, since these are very common and
2589 -- would generate many annoying positive warnings.
2590 -- The default is that such warnings are not
2591 -- generated.
2592 --
2593 -- NOOBSOLESCENT Disables warnings on use of obsolescent
2594 -- features.
2595 --
2596 -- OPTIONAL Activate all optional warning messages.
2597 -- See other options under this qualifier

2639 --
2640 -- NOUNCHECKED_CONVERSIONS Suppress warnings for unchecked conversions.
2641 --
2642 -- UNINITIALIZED Generate warnings for uninitialized variables.
2643 -- This is a GCC option, not an Ada option.
2644 -- You must also specify the /OPTIMIZE qualifier

2648 --
2649 -- UNREFERENCED_FORMALS Activate warnings on unreferenced formals.
2650 -- Causes a warning to be generated if a formal

2653 -- on using option ALL or UNUSED.
2654 --
2655 -- NOUNREFERENCED_FORMALS Suppress warnings on unreferenced formals.
2656 -- Suppresses warnings for unreferenced formal
2657 -- parameters. Note that the combination UNUSED
2658 -- followed by NOUNREFERENCED_FORMALS has the
2659 -- effect of warning on unreferenced entities
2660 -- other than subprogram formals.
2661 --
2662 -- UNUSED Activates warnings to be generated for entities
2663 -- that are defined but not referenced, and for
2664 -- units that are with'ed and not referenced. In
2665 -- the case of packages, a warning is also
2666 -- generated if no entities in the package are
2667 -- referenced. This means that if the package
2668 -- is referenced but the only references are in
2669 -- use clauses or renames declarations, a warning
2670 -- is still generated. A warning is also generated
2671 -- for a generic package that is with'ed but never
2672 -- instantiated. In the case where a package or
2673 -- subprogram body is compiled, and there is a
2674 -- with on the corresponding spec that is only

2718 -- /NOWIDE_CHARACTER_ENCODING (D)
2719 -- /WIDE_CHARACTER_ENCODING[=encode-type]
2720 --
2721 -- Specifies the mechanism used to encode wide characters. 'encode-type'
2722 -- is one of the following:
2723 --
2724 -- BRACKETS (D) A wide character is encoded as ["xxxx"] where XXXX
2725 -- are four hexadecimal digits representing the coding
2726 -- ('Pos value) of the character in type
2727 -- Wide_Character. The hexadecimal digits may use upper
2728 -- or lower case letters.
2729 --
2730 -- This notation can also be used for upper half
2731 -- Character values using the format ["xx"] where XX is
2732 -- two hexadecimal digits representing the coding ('Pos
2733 -- value) of the character in type Character (or
2734 -- Wide_Character). The hexadecimal digits may use upper
2735 -- of lower case.
2736 --
2737 -- NONE No wide characters are allowed. Same
2738 -- as /NOWIDE_CHARCTER_ENCODING.
2739 --
2740 -- HEX In this encoding, a wide character is represented by
2741 -- the following five character sequence: ESC a b c d
2742 -- Where 'a', 'b', 'c', and 'd' are the four hexadecimal
2743 -- characters (using uppercase letters) of the wide
2744 -- character code. For example, ESC A345 is used to
2745 -- represent the wide character with code 16#A345#. This
2746 -- scheme is compatible with use of the full
2747 -- Wide_Character set.
2748 --
2749 -- UPPER The wide character with encoding 16#abcd# where the
2750 -- upper bit is on (in other words, "a" is in the range
2751 -- 8-F) is represented as two bytes, 16#ab# and 16#cd#.
2752 -- The second byte may never be a format control
2753 -- character, but is not required to be in the upper
2754 -- half. This method can be also used for shift-JIS or
2755 -- EUC, where the internal coding matches the external
2756 -- coding.
2757 --
2758 -- SHIFT_JIS A wide character is represented by a two-character
2759 -- sequence, 16#ab# and 16#cd#, with the restrictions
2760 -- described for upper-half encoding as described above.
2761 -- The internal character code is the corresponding JIS
2762 -- character according to the standard algorithm for
2763 -- Shift-JIS conversion. Only characters defined in the
2764 -- JIS code set table can be used with this encoding
2765 -- method.
2766 --
2767 -- UTF8 A wide character is represented using
2768 -- UCS Transformation Format 8 (UTF-8) as defined in Annex
2769 -- R of ISO 10646-1/Am.2. Depending on the character
2770 -- value, the representation is a one, two, or three byte
2771 -- sequence:
2772 --
2773 -- 16#0000#-16#007f#: 2#0xxxxxxx#
2774 -- 16#0080#-16#07ff#: 2#110xxxxx# 2#10xxxxxx#
2775 -- 16#0800#-16#ffff#: 2#1110xxxx# 2#10xxxxxx# 2#10xxxxxx#
2776 --
2777 -- where the xxx bits correspond to the left-padded bits
2778 -- of the the 16-bit character value. Note that all lower
2779 -- half ASCII characters are represented as ASCII bytes
2780 -- and all upper half characters and other wide characters
2781 -- are represented as sequences of upper-half (The full
2782 -- UTF-8 scheme allows for encoding 31-bit characters as
2783 -- 6-byte sequences, but in this implementation, all UTF-8
2784 -- sequences of four or more bytes length will be treated
2785 -- as illegal).
2786 --
2787 -- EUC A wide character is represented by a two-character
2788 -- sequence 16#ab# and 16#cd#, with both characters being
2789 -- in the upper half. The internal character code is the
2790 -- corresponding JIS character according to the EUC
2791 -- encoding algorithm. Only characters defined in the JIS
2792 -- code set table can be used with this encoding method.
2796 -- NODOC (see /WIDE_CHARACTER_ENCODING)
2800 -- /NOXDEBUG (D)
2801 -- /XDEBUG
2802 --
2803 -- Output expanded source files for source level debugging.
2804 -- The expanded source (see /EXPAND_SOURCE) is written to files
2805 -- with names formed by appending "_DG" to the input file name,
