24 ------------------------------------------------------------------------------
26 -- This package contains, for each of the command of the GNAT driver, one
27 -- constant array; each component of this array is a string that defines,
28 -- in coded form as explained below, the conversion of a VMS qualifier of the
29 -- command to the corresponding switch of the GNAT tool corresponding to the
30 -- command.
32 -- This package is used by the GNAT driver to invokes the GNAT tools with the
33 -- switches corresponding to the VMS qualifier and by the Project Manager to
34 -- convert VMS qualifiers in project files to their corresponding switch
35 -- values.
37 -- This package is also an input to the tool that generates the VMS GNAT
38 -- help information automatically.
40 -- NOTE: the format of this package must follow the following rules, so that
41 -- the VMS GNAT help tool works properly:
43 -- - Each command zone (where the eventual qualifiers are declared) must
44 -- begin with a boxed comment of the form:
46 -- ---------------------------------
47 -- -- Switches for GNAT <COMMAND> --
48 -- ---------------------------------
50 -- where <COMMAND> is the name of a GNAT command in capital letters, for
51 -- example BIND, COMPILE, XREF, ...
53 -- - each qualifier declaration must be followed either by
54 -- - a comment starting with "-- NODOC", to indicate that there is
55 -- no documentation for this qualifier, or
56 -- - a contiguous sequence of comments that constitute the
57 -- documentation of the qualifier.
59 -- - each command zone ends with the declaration of the constant array
60 -- for the command, of the form:
62 -- <Command>__Switches : aliased constant Switches :=
66 ----------------
67 -- QUALIFIERS --
68 ----------------
70 -- The syntax of a qualifier declaration is as follows:
72 -- SWITCH_STRING ::= "/ command-qualifier-name TRANSLATION"
74 -- TRANSLATION ::=
75 -- DIRECT_TRANSLATION
76 -- | DIRECTORIES_TRANSLATION
77 -- | FILE_TRANSLATION
78 -- | NO_SPACE_FILE_TRANSL
79 -- | NUMERIC_TRANSLATION
80 -- | STRING_TRANSLATION
81 -- | OPTIONS_TRANSLATION
82 -- | COMMANDS_TRANSLATION
83 -- | ALPHANUMPLUS_TRANSLATION
84 -- | OTHER_TRANSLATION
86 -- DIRECT_TRANSLATION ::= space UNIX_SWITCHES
87 -- DIRECTORIES_TRANSLATION ::= =* UNIX_SWITCH *
88 -- DIRECTORY_TRANSLATION ::= =% UNIX_SWITCH %
89 -- FILE_TRANSLATION ::= =@ UNIX_SWITCH @
90 -- NO_SPACE_FILE_TRANSL ::= =< UNIX_SWITCH >
91 -- NUMERIC_TRANSLATION ::= =# UNIX_SWITCH # | # number #
92 -- STRING_TRANSLATION ::= =" UNIX_SWITCH "
93 -- OPTIONS_TRANSLATION ::= =OPTION {space OPTION}
94 -- COMMANDS_TRANSLATION ::= =? ARGS space command-name
95 -- ALPHANUMPLUS_TRANSLATION ::= =| UNIX_SWITCH |
97 -- UNIX_SWITCHES ::= UNIX_SWITCH {, UNIX_SWITCH}
99 -- UNIX_SWITCH ::= unix-switch-string | !unix-switch-string | `string'
101 -- OPTION ::= option-name space UNIX_SWITCHES
103 -- ARGS ::= -cargs | -bargs | -largs
105 -- Here command-qual is the name of the switch recognized by the GNATCmd.
106 -- This is always given in upper case in the templates, although in the
107 -- actual commands, either upper or lower case is allowed.
109 -- The unix-switch-string always starts with a minus, and has no commas
110 -- or spaces in it. Case is significant in the unix switch string. If a
111 -- unix switch string is preceded by the not sign (!) it means that the
112 -- effect of the corresponding command qualifier is to remove any previous
113 -- occurrence of the given switch in the command line.
115 -- The DIRECTORIES_TRANSLATION format is used where a list of directories
116 -- is given. This possible corresponding formats recognized by GNATCmd are
117 -- as shown by the following example for the case of PATH
119 -- PATH=direc
120 -- PATH=(direc,direc,direc,direc)
122 -- When more than one directory is present for the DIRECTORIES case, then
123 -- multiple instances of the corresponding unix switch are generated,
124 -- with the file name being substituted for the occurrence of *.
126 -- The FILE_TRANSLATION format is similar except that only a single
127 -- file is allowed, not a list of files, and only one unix switch is
128 -- generated as a result.
130 -- the NO_SPACE_FILE_TRANSL is similar to FILE_TRANSLATION, except that
131 -- no space is inserted between the switch and the file name.
133 -- The NUMERIC_TRANSLATION format is similar to the FILE_TRANSLATION case
134 -- except that the parameter is a decimal integer in the range 0 to 999999.
136 -- For the OPTIONS_TRANSLATION case, GNATCmd similarly permits one or
137 -- more options to appear (although only in some cases does the use of
138 -- multiple options make logical sense). For example, taking the
139 -- case of ERRORS for GCC, the following are all allowed:
141 -- /ERRORS=BRIEF
142 -- /ERRORS=(FULL,VERBOSE)
143 -- /ERRORS=(BRIEF IMMEDIATE)
145 -- If no option is provided (e.g. just /ERRORS is written), then the
146 -- first option in the list is the default option. For /ERRORS this
147 -- is NORMAL, so /ERRORS with no option is equivalent to /ERRORS=NORMAL.
149 -- The COMMANDS_TRANSLATION case is only used for gnatmake, to correspond
150 -- to the use of -cargs, -bargs and -largs (the ARGS string as indicated
151 -- is one of these three possibilities). The name given by COMMAND is the
152 -- corresponding command name to be used to interpret the switches to be
153 -- passed on. Switches of this type set modes, e.g. /COMPILER_QUALIFIERS
154 -- sets the mode so that all subsequent switches, up to another switch
155 -- with COMMANDS_TRANSLATION apply to the corresponding commands issued
156 -- by the make utility. For example
158 -- /COMPILER_QUALIFIERS /LIST /BINDER_QUALIFIERS /MAIN
159 -- /COMPILER_QUALIFIERS /NOLIST /COMPILE_CHECKS=SYNTAX
161 -- Clearly these switches must come at the end of the list of switches
162 -- since all subsequent switches apply to an issued command.
164 -- For the DIRECT_TRANSLATION case, an implicit additional qualifier
165 -- declaration is created by prepending NO to the name of the qualifier,
166 -- and then inverting the sense of the UNIX_SWITCHES string. For example,
167 -- given the qualifier definition:
169 -- "/LIST -gnatl"
171 -- An implicit qualifier definition is created:
173 -- "/NOLIST !-gnatl"
175 -- In the case where, a ! is already present, inverting the sense of the
176 -- switch means removing it.
179 -- A synonym to shorten the table
182 -- String pointer type used throughout
185 -- Type used for array of switches

433 -- /PROJECT_FILE=filename
434 --
435 -- Specifies the main project file to be used. The project files rooted
436 -- at the main project file will be parsed before the invocation of the

439 -- and ADA_PRJ_OBJECTS_FILE.
448 -- /READ_SOURCES[=(keyword[,...])]
449 -- /NOREAD_SOURCES
450 --
451 -- The following keyword are accepted:
452 --
453 -- ALL (D) Require source files to be present. In this mode, the
454 -- binder insists on being able to locate all source files
455 -- that are referenced and checks their consistency. In
456 -- normal mode, if a source file cannot be located it is
457 -- simply ignored. If you specify the ALL keyword, a
458 -- missing source file is an error.
459 --
460 -- NONE Exclude source files. In this mode, the binder only
461 -- checks that ALI files are consistent with one another.
462 -- source files are not accessed. The binder runs faster
463 -- in this mode, and there is still a guarantee that the
464 -- resulting program is self-consistent.
465 --
466 -- If a source file has been edited since it was last
467 -- compiled and you specify the NONE keyword, the binder
468 -- will not detect that the object file is out of date
469 -- with the source file.
470 --
471 -- This is the same as specifying /NOREAD_SOURCES.
472 --
473 -- AVAILABLE Check that object files are consistent with one
474 -- another and are consistent with any source files that
475 -- can be located.
479 -- NODOC (see /READ_SOURCES)
483 -- /RENAME_MAIN=xxx
484 --
485 -- Renames the generated main program from main to xxx.
486 -- This is useful in the case of some cross-building environments, where
487 -- the actual main program is separate from the one generated
488 -- by GNAT BIND.
497 -- /REPORT_ERRORS[=(keyword[,...])]
498 -- VERBOSE (D)
499 -- BRIEF
500 -- DEFAULT
501 -- /NOREPORT_ERRORS
502 --
503 -- With the DEFAULT keyword (which is not the default when the binder is
504 -- run from GNAT BIND) or the /NOREPORT_ERRORS qualifier, brief error
505 -- messages are generated to SYS$ERROR. If the VERBOSE keyword is
506 -- present, a header is written to SYS$OUTPUT and any error messages are
507 -- directed to SYS$OUTPUT All that is written to SYS$ERROR is a brief
508 -- summary message.
509 --
510 -- If the BRIEF keyword is specified, the binder will generate brief error
511 -- messages to SYS$ERROR even if verbose mode is specified. This is
512 -- relevant only when used together with the VERBOSE keyword or /VERBOSE
513 -- qualifier.
517 -- NODOC (see /REPORT_ERRORS)
521 -- /NORESTRICTION_LIST (D)
522 -- /RESTRICTION_LIST
523 --
524 -- Generate list of pragma Restrictions that could be applied to the
525 -- current unit. This is useful for code audit purposes, and also may be
526 -- used to improve code generation in some cases.
533 -- /RETURN_CODES=POSIX (D)
534 -- /RETURN_CODES=VMS
535 --
536 -- Specifies the style of default exit code returned. Must be used in
537 -- conjunction with and match the Link qualifier with same name.
538 --
539 -- POSIX (D) Return Posix success (0) by default.
540 --
541 -- VMS Return VMS success (1) by default.
545 -- /RUNTIME_SYSTEM=xxx
546 --
547 -- Binds against an alternate runtime system named xxx or RTS-xxx.
551 -- /SEARCH=(directory[,...])
552 --
553 -- When looking for source or object files also look in directories
554 -- specified.
555 --
556 -- This is the same as specifying both /LIBRARY_SEARCH and /SOURCE_SEARCH
557 -- for a directory.
561 -- /SHARED
562 -- /NOSHARED
563 --
564 -- Link against a shared GNAT run time when available.
568 -- /TIME_SLICE=nnn
569 --
570 -- Set the time slice value to nnn milliseconds. A value of zero means no
571 -- time slicing and also indicates to the tasking run time to match as
572 -- close as possible to the annex D requirements of the RM.
576 -- /SOURCE_SEARCH=(directory[,...])
577 --
578 -- When looking for source files also look in directories specified.
582 -- /STATIC
583 -- /NOSTATIC
584 --
585 -- Link against a static GNAT run time.
589 -- /STORE_TRACEBACKS (D)
590 -- /NOSTORE_TRACEBACKS
591 --
592 -- Store tracebacks in exception occurrences.
593 -- This is the default on VMS, with the zero-cost exception mechanism.
594 -- This qualifier has no impact, except when using the setjmp/longjmp
595 -- exception mechanism, with the GNAT COMPILE qualifier /LONGJMP_SETJMP.
599 -- /SUBDIRS=dir
600 --
601 -- The actual directories (object, exec, library, ...) are subdirectories
602 -- of the directory specified in the project file. If the subdirectory
603 -- does not exist, it is created automatically.
607 -- /TIME_STAMP_CHECK (D)
608 --
609 -- Time stamp errors will be treated as errors.
610 --
611 -- /NOTIME_STAMP_CHECK
612 --
613 -- Ignore time stamp errors. Any time stamp error messages are treated as
614 -- warning messages. This switch essentially disconnects the normal
615 -- consistency checking, and the resulting program may have undefined
616 -- semantics if inconsistent units are present.
617 --
618 -- This means that /NOTIME_STAMP_CHECK should be used only in unusual
619 -- situations, with extreme care.
623 -- /VERBOSE (D)
624 -- /NOVERBOSE
625 --
626 -- Equivalent to /REPORT_ERRORS=VERBOSE.
635 -- /WARNINGS[=(keyword[,...])]
636 -- /NOWARNINGS
637 --
638 -- The following keywords are supported:
639 --
640 -- NORMAL (D) Print warning messages and treat them as warning.
641 -- SUPPRESS Suppress all warning messages (same as /NOWARNINGS).
642 -- ERROR Treat any warning messages as fatal errors
646 -- NODOC (see /WARNINGS)
661 -- /NOWIDE_CHARACTER_ENCODING (D)
662 -- /WIDE_CHARACTER_ENCODING[=encode-type]
663 --
664 -- Specifies the mechanism used to encode wide characters, overriding
665 -- the default as set by the /WIDE_CHARACTER_ENCODING option for the
666 -- compilation of the main program.
670 -- /NOZERO_MAIN (D)
671 -- /ZERO_MAIN
672 --
673 -- Normally the binder checks that the unit name given on the command line
674 -- corresponds to a suitable main subprogram. When /ZERO_MAIN is used,
675 -- a list of ALI files can be given, and the execution of the program
676 -- consists of elaboration of these units in an appropriate order.

1200 --
1201 -- Although GNAT is primarily an Ada 95 compiler, it accepts this
1202 -- qualifier to specify that an Ada 83 mode program is being compiled. If
1203 -- you specify this qualifier, GNAT rejects Ada 95 extensions and applies
1204 -- Ada 83 semantics. It is not possible to guarantee this qualifier does
1205 -- a perfect job; for example, some subtle tests of pathological cases,
1206 -- such as are found in ACVC tests that have been removed from the ACVC
1207 -- suite for Ada 95, may not compile correctly. However for practical
1208 -- purposes, using this qualifier should ensure that programs that
1209 -- compile correctly under the /83 qualifier can be ported reasonably
1210 -- easily to an Ada 83 compiler. This is the main use of this qualifier.
1211 --
1212 -- With few exceptions (most notably the need to use "<>" on
1213 -- unconstrained generic formal parameters), it is not necessary to use
1214 -- this qualifier switch when compiling Ada 83 programs, because, with
1215 -- rare and obscure exceptions, Ada 95 is upwardly compatible with Ada
1216 -- 83. This means that a correct Ada 83 program is usually also a correct
1217 -- Ada 95 program.

1259 -- Use to tell the compiler to assume that all objects have valid values
1261 -- mode, the compiler assumes that values may be invalid unless it can

1282 -- /NOCHECKS
1283 -- /CHECKS[=(keyword[,...])]
1284 --
1285 -- If you compile with the default options, GNAT will insert many runtime
1286 -- checks into the compiled code, including code that performs range
1287 -- checking against constraints, but not arithmetic overflow checking for
1288 -- integer operations (including division by zero) or checks for access
1289 -- before elaboration on subprogram calls. All other runtime checks, as
1290 -- required by the Ada 95 Reference Manual, are generated by default.
1291 --
1292 -- You may specify one or more of the following keywords to the /CHECKS
1293 -- qualifier to modify this behavior:
1294 --
1295 -- DEFAULT The behavior described above. This is the default
1296 -- if the /CHECKS qualifier is not present on the
1297 -- command line. Same as /NOCHECKS.
1298 --
1299 -- OVERFLOW Enables overflow checking for integer operations and
1300 -- checks for access before elaboration on subprogram
1301 -- calls. This causes GNAT to generate slower and larger
1302 -- executable programs by adding code to check for both
1303 -- overflow and division by zero (resulting in raising
1304 -- "Constraint_Error" as required by Ada semantics).
1305 -- Similarly, GNAT does not generate elaboration check
1306 -- by default, and you must specify this keyword to
1307 -- enable them.
1308 --
1309 -- Note that this keyword does not affect the code
1310 -- generated for any floating-point operations; it
1311 -- applies only to integer operations. For the case of
1312 -- floating-point, GNAT has the "Machine_Overflows"
1313 -- attribute set to "False" and the normal mode of
1314 -- operation is to generate IEEE NaN and infinite values
1315 -- on overflow or invalid operations (such as dividing
1316 -- 0.0 by 0.0).
1317 --
1318 -- ELABORATION Enables dynamic checks for access-before-elaboration
1319 -- on subprogram calls and generic instantiations.
1320 --
1321 -- ASSERTIONS The pragmas "Assert" and "Debug" normally have no
1322 -- effect and are ignored. This keyword causes "Assert"
1323 -- and "Debug" pragmas to be activated, as well as
1324 -- "Check", "Precondition" and "Postcondition" pragmas.
1325 --
1326 -- SUPPRESS_ALL Suppress all runtime checks as though you have
1327 -- "pragma Suppress (all_checks)" in your source. Use

1332 -- UNSUPPRESS_ALL Cancels effect of previous SUPPRESS_ALL.
1333 --
1334 -- DEFAULT Suppress the effect of any option OVERFLOW or

1336 --
1337 -- FULL (D) Similar to OVERFLOW, but suppress the effect of any
1338 -- option ELABORATION or SUPPRESS_ALL.
1339 --
1340 -- These keywords only control the default setting of the checks. You
1341 -- may modify them using either "Suppress" (to remove checks) or
1342 -- "Unsuppress" (to add back suppressed checks) pragmas in your program

1347 -- NODOC (see /CHECKS)
1351 -- /NOCOMPRESS_NAMES (D)
1352 -- /COMPRESS_NAMES
1353 --
1354 -- Compress debug information and external symbol name table entries.
1355 -- In the generated debugging information, and also in the case of long
1356 -- external names, the compiler uses a compression mechanism if the name
1357 -- is very long. This compression method uses a checksum, and avoids

1371 --
1372 -- Look for source files in the default directory.
1376 -- /DATA_PREPROCESSING=file_name
1377 --
1378 -- This qualifier indicates to the compiler the file name (without
1379 -- directory information) of the preprocessor data file to use.
1380 -- The preprocessor data file should be found in the source directories.
1381 --
1382 -- A preprocessing data file is a text file with significant lines
1383 -- indicating how should be preprocessed either a specific source or all
1384 -- sources not mentioned in other lines. A significant line is a non
1385 -- empty, non comment line. Comments are similar to Ada comments.
1386 --
1387 -- Each significant line starts with either a literal string or the
1388 -- character '*'. A literal string is the file name (without directory
1389 -- information) of the source to preprocess. A character '*' indicates the
1390 -- preprocessing for all the sources that are not specified explicitly on
1391 -- other lines. It is an error to have two lines with the same file name
1392 -- or two lines starting with the character '*'.
1393 --
1394 -- After the file name or the character '*', another optional literal
1395 -- string indicating the file name of the definition file to be used for
1396 -- preprocessing. (see 15.3 Form of Definitions File. The definition files
1397 -- are found by the compiler in one of the source directories. In some
1398 -- cases, when compiling a source in a directory other than the current
1399 -- directory, if the definition file is in the current directory, it may
1400 -- be necessary to add the current directory as a source directory through
1401 -- qualifier "/SEARCH=[]", otherwise the compiler would not find the
1402 -- definition file.
1403 --
1404 -- Then, optionally, switches similar to those of gnatprep may be found.
1405 -- Those switches are:
1406 --
1407 -- -b Causes both preprocessor lines and the lines deleted by
1408 -- preprocessing to be replaced by blank lines, preserving
1409 -- the line number. This switch is always implied;
1410 -- however, if specified after `-c' it cancels the effect
1411 -- of `-c'.
1412 --
1413 -- -c Causes both preprocessor lines and the lines deleted by
1414 -- preprocessing to be retained as comments marked with
1415 -- the special string "--! ".
1416 --
1417 -- -Dsymbol=value Define or redefine a symbol, associated with value.
1418 -- A symbol is an Ada identifier, or an Ada reserved word,
1419 -- with the exception of "if", "else", "elsif", "end",
1420 -- "and", "or" and "then". value is either a literal
1421 -- string, an Ada identifier or any Ada reserved word.
1422 -- A symbol declared with this switch replaces a symbol
1423 -- with the same name defined in a definition file.
1424 --
1425 -- -s Causes a sorted list of symbol names and values to be
1426 -- listed on the standard output file.
1427 --
1428 -- -u Causes undefined symbols to be treated as having the
1429 -- value FALSE in the context of a preprocessor test.
1430 -- In the absence of this option, an undefined symbol
1431 -- in a #if or #elsif test will be treated as an error.
1432 --
1433 -- Examples of valid lines in a preprocessor data file:
1434 --
1435 -- "toto.adb" "prep.def" -u
1436 -- -- preprocess "toto.adb", using definition file "prep.def",

1651 --
1652 -- 1 The basic character set is Latin-1. This character
1653 -- set is defined by ISO standard 8859, part 1. The lower
1654 -- half (character codes 16#00# ... 16#7F#) is identical
1655 -- to standard ASCII coding, but the upper half is used
1656 -- to represent additional characters. This includes
1657 -- extended letters used by European languages, such as
1658 -- the umlaut used in German.
1659 --
1660 -- You may use any of these extended characters freely
1661 -- in character or string literals. In addition, the
1662 -- extended characters that represent letters can be

1674 -- PC IBM PC code page 437. This code page is the normal
1675 -- default for PCs in the U.S. It corresponds to the
1676 -- original IBM PC character set. This set has some, but
1677 -- not all, of the extended Latin-1 letters, but these
1678 -- letters do not have the same encoding as Latin-1. In
1679 -- this mode, these letters are allowed in identifiers
1680 -- with uppercase and lowercase equivalence.
1681 --
1682 -- PC850 This code page (850) is a modification of 437 extended
1683 -- to include all the Latin-1 letters, but still not with
1684 -- the usual Latin-1 encoding. In this mode, all these
1685 -- letters are allowed in identifiers with uppercase and
1686 -- lower case equivalence.
1687 --
1688 -- FULL_UPPER Any character in the range 80-FF allowed in

1731 -- /NOINLINE (D)
1732 -- /INLINE[=keyword]
1733 --
1734 -- Selects the level of inlining for your program. In the absence of this
1735 -- qualifier, GNAT does not attempt inlining across units and does not
1736 -- need to access the bodies of subprograms for which "pragma Inline" is
1737 -- specified if they are not in the current unit.
1738 --
1739 -- The supported keywords are as follows:
1740 --
1741 -- PRAGMA (D) Recognize and process "Inline" pragmas. However,
1742 -- for the inlining to actually occur, optimization
1743 -- must be enabled. This enables inlining across unit
1744 -- boundaries, that is, inlining a call in one unit of
1745 -- a subprogram declared in a with'ed unit. The compiler
1746 -- will access these bodies, creating an extra source
1747 -- dependency for the resulting object file, and where
1748 -- possible, the call will be inlined.
1749 --
1750 -- This qualifier also turns on full optimization and
1751 -- requests GNAT to try to attempt automatic inlining
1752 -- of small subprograms within a unit.
1753 --
1754 -- Specifying /OPTIMIZE=NONE will disable the main effect
1755 -- of this qualifier, but you may specify other
1756 -- optimization options, to get either lower
1757 -- (/OPTIMIZE=SOME) or higher (/OPTIMIZE=UNROLL_LOOPS)
1758 -- levels of optimization.
1759 --
1760 -- FULL Front end inlining. The front end inlining activated
1761 -- by this switch is generally more extensive, and quite
1762 -- often more effective than the standard PRAGMA inlining
1763 -- mode. It will also generate additional dependencies.
1764 --
1765 -- SUPPRESS Suppresses all inlining, even if other optimization
1766 -- or inlining switches are set.

1823 -- qualifier is also present.
1827 -- /MAPPING_FILE=file_name
1828 --
1829 -- Use mapping file file_name
1830 --
1831 -- A mapping file is a way to communicate to the compiler two mappings:
1832 -- from unit names to file names (without any directory information) and
1833 -- from file names to path names (with full directory information).
1834 -- These mappings are used by the compiler to short-circuit the path
1835 -- search.
1836 --
1837 -- The use of mapping files is not required for correct operation of the
1838 -- compiler, but mapping files can improve efficiency, particularly when
1839 -- sources are read over a slow network connection. In normal operation,
1840 -- you need not be concerned with the format or use of mapping files,
1841 -- and /MAPPING_FILE is not a qualifier that you would use explicitly.
1842 -- It is intended only for use by automatic tools such as GNAT MAKE
1843 -- running under the project file facility. The description here of the
1844 -- format of mapping files is provided for completeness and for possible
1845 -- use by other tools.
1846 --
1847 -- A mapping file is a sequence of sets of three lines. In each set, the
1848 -- first line is the unit name, in lower case, with "%s" appended for
1849 -- specifications and "%b" appended for bodies; the second line is the
1850 -- file name; and the third line is the path name.
1851 --
1852 -- Example:
1853 --
1854 -- main%b
1855 -- main.2_ada
1856 -- /gnat/project1/sources/main.2_ada
1857 --
1858 -- When qualifier ?MAPPING_FILE is specified, the compiler will create in
1859 -- memory the two mappings from the specified file. If there is any
1860 -- problem (non existent file, truncated file or duplicate entries),
1861 -- no mapping will be created.
1862 --
1863 -- Several /MAPPING_FILE qualifiers may be specified; however, only the
1864 -- last one on the command line will be taken into account.
1865 --
1866 -- When using a project file, GNAT MAKE creates a temporary mapping file
1867 -- and communicates it to the compiler using this switch.
1876 -- /MESSAGES_PROJECT_FILE[=messages-option]
1877 --
1878 -- Specifies the "verbosity" of the parsing of project files.
1879 -- messages-option may be one of the following:
1880 --
1881 -- DEFAULT (D) No messages are output if there is no error or warning.
1882 --
1883 -- MEDIUM A small number of messages are output.
1884 --
1885 -- HIGH A great number of messages are output, most of them not
1886 -- being useful for the user.
1890 -- /MAX_NESTING=nnn
1891 --
1892 -- Set maximum level of nesting of constructs (including subprograms,
1893 -- loops, blocks, packages, and conditionals).
1894 -- The level of nesting must not exceed the given value nnn.
1895 -- A value of zero disable this style check (not enabled by default).
1899 -- /NO_GNAT_ADC
1900 --
1901 -- Cause the compiler to ignore any configuration pragmas file GNAT.ADC
1902 -- in the default directory. Implied by qualifier /PROJECT_FILE.
1903 -- Often used in conjunction with qualifier /CONFIGURATION_PRAGMAS_FILE.
1907 -- /NOLOAD
1908 --
1909 -- Cause the compiler to operate in semantic check mode with full
1910 -- checking for all illegalities specified in the reference manual, but
1911 -- without generation of any source code (no object or ALI file
1912 -- generated).
1913 --
1914 -- Since dependent files must be accessed, you must follow the GNAT
1915 -- semantic restrictions on file structuring to operate in this mode:
1916 --
1917 -- o The needed source files must be accessible.
1918 -- o Each file must contain only one compilation unit.
1919 -- o The file name and unit name must match.
1920 --
1921 -- The output consists of error messages as appropriate. No object file
1922 -- or ALI file is generated. The checking corresponds exactly to the
1923 -- notion of legality in the Ada reference manual.
1924 --
1925 -- Any unit can be compiled in semantics-checking-only mode, including
1926 -- units that would not normally be compiled (generic library units,
1927 -- subunits, and specifications where a separate body is present).
1931 -- /NOSTD_INCLUDES
1932 --
1933 -- Do not look in the default directory for source files of the runtime.
1937 -- /NOSTD_LIBRARIES
1938 --
1939 -- Do not look for library files in the system default directory.
1943 -- /NOWARNING_PRAGMAS
1944 --
1945 -- Causes all Warnings pragmas to be ignored. Useful to check if the
1946 -- program has obsolete warnings pragmas that are hiding problems.
1965 -- /NOOPTIMIZE (D)
1966 -- /OPTIMIZE[=(keyword[,...])]
1967 --
1968 -- Selects the level of optimization for your program. The supported
1969 -- keywords are as follows:
1970 --
1971 -- ALL (D) Perform most optimizations, including those that
1972 -- may be expensive.
1973 --
1974 -- NONE Do not do any optimizations. Same as /NOOPTIMIZE.
1975 --
1976 -- SOME Perform some optimizations, but omit ones that
1977 -- are costly in compilation time.
1978 --
1979 -- SPACE Optimize space usage
1980 --
1981 -- DEVELOPMENT Same as SOME.
1982 --
1983 -- INLINING Full optimization, and also attempt automatic inlining
1984 -- of small subprograms within a unit
1985 --
1986 -- UNROLL_LOOPS Try to unroll loops. This keyword may be specified
1987 -- with any keyword above other than NONE. Loop
1988 -- unrolling usually, but not always, improves the
1989 -- performance of programs.
1990 --
1991 -- NO_STRICT_ALIASING
1992 -- Suppress aliasing analysis. When optimization is
1993 -- enabled (ALL or SOME above), the compiler assumes
1994 -- that pointers do in fact point to legitimate values
1995 -- of the pointer type (allocated from the proper pool).
1996 -- If this assumption is violated, e.g. by the use of
1997 -- unchecked conversion, then it may be necessary to
1998 -- suppress this assumption using this keyword (which
1999 -- may be specified only in conjunction with any
2000 -- keyword above, other than NONE).
2004 -- NODOC (see /OPTIMIZE)
2008 -- /OUTPUT_FILE=fname
2009 --
2010 -- This has the same effect as /LIST except that the output is written
2011 -- to a file instead of to standard output. If the given fname
2012 -- does not start with a period, then it is the full name of the file
2013 -- to be written. If fname starts with a period, the name of the file
2014 -- is the concatenation of to the name of the file being compiled with
2015 -- fname where the period is replace by an underline. For example, if
2016 -- file xyz.adb is compiled with -gnatl=.lst, then the output is written
2017 -- to file xyz.adb_lst.
2028 -- /POINTER_SIZE=64 (D)
2029 -- /POINTER_SIZE[=(keyword[,...])]
2030 --
2031 -- Change how pointers and descriptors are allocated. The following
2032 -- keywords are supported:
2033 --
2034 -- 64 (D) Allocate heap pointers in 64bit space except as
2035 -- constrained by a 32bit size clause or by
2036 -- Convention_C and generate 64bit descriptors for
2037 -- Descriptor mechanisms for calling imported
2038 -- subprograms and accept both 64bit and 32bit
2039 -- descriptors for calls to exported subprograms.
2040 --
2041 -- LONG Equivalent to option 64.
2042 --
2043 -- 32 Allocate all heap pointers in 32bit space and
2044 -- generate 32bit descriptors for Descriptor
2045 -- mechanisms for calling imported subprograms.
2046 --
2047 -- SHORT Equivalent to option 32.
2051 -- /NOPOLLING (D)
2052 -- /POLLING
2053 --
2054 -- Enable polling. See the description of pragma Polling in the GNAT
2055 -- Reference Manual for full details.
2059 -- /PROJECT_FILE=filename
2060 --
2061 -- Specifies the main project file to be used. The project files rooted
2062 -- at the main project file will be parsed before the invocation of the
2063 -- compiler. The source and object directories to be searched will be
2064 -- communicated to the compiler through logical names
2065 -- ADA_PRJ_INCLUDE_FILE and ADA_PRJ_OBJECTS_FILE.
2069 -- /PRINT_STANDARD
2070 --
2071 -- cause the compiler to output a representation of package Standard
2072 -- in a form very close to standard Ada. It is not quite possible to
2073 -- do this and remain entirely Standard (since new numeric base types
2074 -- cannot be created in standard Ada), but the output is easily
2075 -- readable to any Ada programmer, and is useful to determine the
2076 -- characteristics of target dependent types in package Standard.
2081 -- /NO_TREAT_RESTRICTIONS_AS_WARNINGS (D)
2082 -- /TREAT_RESTRICTIONS_AS_WARNINGS
2083 --
2084 -- Causes all restrictions to be treated as warnings (pragma Restriction

2099 -- /NOREPORT_ERRORS (D)
2100 -- /REPORT_ERRORS[=(keyword[,...])]
2101 --
2102 -- Change the way errors are reported. The following keywords are

2106 -- to SYS$OUTPUT.
2107 --
2108 -- BRIEF Generate the brief format error messages to
2109 -- SYS$OUTPUT as well as the verbose format message or
2110 -- full listing.
2111 --
2112 -- FULL Normally, the compiler suppresses error messages that
2113 -- are likely to be redundant. This keyword causes all
2114 -- error messages to be generated. One particular effect
2115 -- is for the case of references to undefined variables.
2116 -- If a given variable is referenced several times, the
2117 -- normal format of messages produces one error. With
2118 -- FULL, each undefined reference produces a separate
2119 -- error message.
2120 --
2121 -- IMMEDIATE Normally, the compiler saves up error messages and
2122 -- generates them at the end of compilation in proper
2123 -- sequence. This keyword causes error messages to be
2124 -- generated as soon as they are detected. The use of
2125 -- IMMEDIATE usually causes error messages to be
2126 -- generated out of sequence. Use it when the compiler
2127 -- blows up due to an internal error. In this case, the
2128 -- error messages may be lost. Sometimes blowups are
2129 -- the result of mishandled error messages, so you may
2130 -- want to run with this keyword to determine whether
2131 -- any error messages were generated.

2337 --
2338 -- Normally, GNAT permits any code layout consistent with the reference

2367 --
2368 -- BLANKS Blanks not allowed at statement end.
2369 -- Trailing blanks are not allowed at the end of

2402 -- ASCII ranges 16#21#..16#2F# or
2403 -- 16#3A#..16#3F#.
2404 --
2405 -- * A line consisting entirely of minus signs,
2406 -- possibly preceded by blanks, is permitted.
2407 -- This allows the construction of box
2408 -- comments where lines of minus signs are
2409 -- used to form the top and bottom of the box.
2410 --
2411 -- * If a comment starts and ends with "--" is
2412 -- permitted as long as at least one blank
2413 -- follows the initial "--". Together with
2414 -- the preceding rule, this allows the
2415 -- construction of box comments, as shown in
2416 -- the following example:
2417 --
2418 -- ---------------------------
2419 -- -- This is a box comment --
2420 -- ---------------------------
2421 --
2422 -- DOS_LINE_ENDINGS Check that no DOS line terminators are present
2423 -- All lines must be terminated by a single
2424 -- ASCII.LF character. In particular the DOS line
2425 -- terminator sequence CR / LF is not allowed).
2426 --
2427 -- END Check end/exit labels.
2428 -- Optional labels on end statements ending
2429 -- subprograms and on exit statements exiting
2430 -- named loops, are required to be present.
2431 --
2432 -- GNAT Enforces a set of style conventions that
2433 -- match the style used in the GNAT source code.
2434 -- This maybe useful when developing code that
2435 -- is eventually intended to be incorporated into
2436 -- GNAT. For further details, see GNAT sources.
2437 --
2438 -- HTABS No horizontal tabs.
2439 -- Horizontal tab characters are not permitted in
2440 -- the source text. Together with the BLANKS
2441 -- (no blanks at end of line) option, this
2442 -- enforces a canonical form for the use of blanks
2443 -- to separate source tokens.
2444 --
2445 -- IF_THEN Check if-then layout.
2446 -- The keyword then must appear either on the
2447 -- same line as the corresponding if, or on a line
2448 -- on its own, lined up under the if with at least
2449 -- one non-blank line in between containing all or
2450 -- part of the condition to be tested.
2451 --
2452 -- KEYWORD Check keyword casing.
2453 -- All keywords must be in lower case (with the
2454 -- exception of keywords such as digits used as
2455 -- attribute names to which this check does not
2456 -- apply).
2457 --
2458 -- LAYOUT Check layout.
2459 -- Layout of statement and declaration constructs
2460 -- must follow the recommendations in the Ada
2461 -- Reference Manual, as indicated by the form of
2462 -- the syntax rules. For example an else keyword
2463 -- must be lined up with the corresponding if
2464 -- keyword.
2465 --
2466 -- There are two respects in which the style rule
2467 -- enforced by this check option are more liberal
2468 -- than those in the Ada Reference Manual.
2469 -- First in the case of record declarations,
2470 -- it is permissible to put the record keyword on
2471 -- the same line as the type keyword, and then
2472 -- the end in end record must line up under type.
2473 -- For example, either of the following two
2474 -- layouts is acceptable:
2475 --
2476 -- type q is record
2477 -- a : integer;
2478 -- b : integer;
2479 -- end record;
2480 --
2481 -- type q is
2482 -- record
2483 -- a : integer;
2484 -- b : integer;
2485 -- end record;
2486 --
2487 -- Second, in the case of a block statement,
2488 -- a permitted alternative is to put the block
2489 -- label on the same line as the declare or begin
2490 -- keyword, and then line the end keyword up under
2491 -- the block label. For example both the following
2492 -- are permitted:
2493 --
2494 --
2495 --
2496 -- Block : declare
2497 -- A : Integer := 3;
2498 -- begin
2499 -- Proc (A, A);
2500 -- end Block;
2501 --
2502 -- Block :
2503 -- declare
2504 -- A : Integer := 3;
2505 -- begin
2506 -- Proc (A, A);
2507 -- end Block;
2508 --
2509 -- The same alternative format is allowed for
2510 -- loops. For example, both of the following are
2511 -- permitted:
2512 --
2513 --
2514 --
2515 -- Clear : while J < 10 loop
2516 -- A (J) := 0;
2517 -- end loop Clear;
2518 --
2519 -- Clear :
2520 -- while J < 10 loop
2521 -- A (J) := 0;
2522 -- end loop Clear;
2523 --
2524 --
2525 --
2526 -- LINE_LENGTH Check maximum line length.
2527 -- The length of source lines must not exceed 79
2528 -- characters, including any trailing blanks
2529 -- The value of 79 allows convenient display on
2530 -- an 80 character wide device or window, allowing
2531 -- for possible special treatment of 80 character
2532 -- lines.
2533 --
2534 -- NONE Clear any previously set style checks.
2535 --
2536 -- ORDERED_SUBPROGRAMS Check order of subprogram bodies.
2537 -- All subprogram bodies in a given scope (e.g.
2538 -- a package body) must be in alphabetical order.
2539 -- The ordering rule uses normal Ada rules for
2540 -- comparing strings, ignoring casing of letters,
2541 -- except that if there is a trailing numeric
2542 -- suffix, then the value of this suffix is used
2543 -- in the ordering (e.g. Junk2 comes before
2544 -- Junk10).
2545 --
2546 -- OVERRIDING_INDICATORS Check that overriding subprograms are
2547 -- explicitly marked as such. The declaration of
2548 -- a primitive operation of a type extension that
2549 -- overrides an inherited operation must carry
2550 -- an overriding indicator.
2551 --
2552 -- PRAGMA Check pragma casing.
2553 -- Pragma names must be written in mixed case,
2554 -- that is, the initial letter and any letter
2555 -- following an underscore must be uppercase.
2556 -- All other letters must be lowercase.
2557 --
2558 -- REFERENCES Check references.
2559 -- All identifier references must be cased in the
2560 -- same way as the corresponding declaration.
2561 -- No specific casing style is imposed on
2562 -- identifiers. The only requirement is for
2563 -- consistency of references with declarations.
2564 --
2565 -- SPECS Check separate specs.
2566 -- Separate declarations ("specs") are required
2567 -- for subprograms (a body is not allowed to serve
2568 -- as its own declaration). The only exception is
2569 -- that parameterless library level procedures are
2570 -- not required to have a separate declaration.
2571 -- This exception covers the most frequent form of
2572 -- main program procedures.
2573 --
2574 -- STANDARD_CASING Check casing of entities in Standard.
2575 -- Any identifier from Standard must be cased to
2576 -- match the presentation in the Ada Reference
2577 -- Manual (for example, Integer and ASCII.NUL).
2578 --
2579 -- TOKEN Check token spacing.
2580 -- The following token spacing rules are enforced:
2581 --
2582 -- * The keywords abs and not must be followed
2583 -- by a space.
2584 --
2585 -- * The token => must be surrounded by spaces.
2586 --
2587 -- * The token <> must be preceded by a space or
2588 -- a left parenthesis.
2589 --
2590 -- * Binary operators other than ** must be
2591 -- surrounded by spaces. There is no
2592 -- restriction on the layout of the ** binary
2593 -- operator.
2594 --
2595 -- * Colon must be surrounded by spaces.
2596 --
2597 -- * Colon-equal (assignment) must be surrounded
2598 -- by spaces.
2599 --
2600 -- * Comma must be the first non-blank character
2601 -- on the line, or be immediately preceded by
2602 -- a non-blank character, and must be followed
2603 -- by a space.
2604 --
2605 -- * If the token preceding a left paren ends
2606 -- with a letter or digit, then a space must
2607 -- separate the two tokens.
2608 --
2609 -- * A right parenthesis must either be the
2610 -- first non-blank character on a line, or it
2611 -- must be preceded by a non-blank character.
2612 --
2613 -- * A semicolon must not be preceded by
2614 -- a space, and must not be followed by
2615 -- a non-blank character.
2616 --
2617 -- * A unary plus or minus may not be followed
2618 -- by a space.
2619 --
2620 -- * A vertical bar must be surrounded by
2621 -- spaces.
2622 --
2623 -- In the above rules, appearing in column one is
2624 -- always permitted, that is, counts as meeting
2625 -- either a requirement for a required preceding
2626 -- space, or as meeting a requirement for no
2627 -- preceding space.
2628 --
2629 -- Appearing at the end of a line is also always
2630 -- permitted, that is, counts as meeting either
2631 -- a requirement for a following space,
2632 -- or as meeting a requirement for no following
2633 -- space.
2634 --
2635 -- UNNECESSARY_BLANK_LINES
2636 -- Check for unnecessary blank lines.
2637 -- A blank line is considered unnecessary if it
2638 -- appears at the end of the file, or if more
2639 -- than one blank line occurs in sequence.
2640 --
2641 -- VTABS No form feeds or vertical tabs.
2642 -- Form feeds or vertical tab characters are not
2643 -- permitted in the source text.
2644 --
2645 -- XTRA_PARENS Check for the use of an unnecessary extra
2646 -- level of parentheses (C - style) around
2647 -- conditions in if statements, while statements
2648 -- and exit statements.
2652 -- NODOC (see /STYLE_CHECKS)
2656 -- /SUBDIRS=dir
2657 --
2658 -- The actual directories (object, exec, library, ...) are subdirectories
2659 -- of the directory specified in the project file. If the subdirectory
2660 -- does not exist, it is created automatically.
2664 -- /SYMBOL_PREPROCESSING="symbol=value"
2665 --
2666 -- Define or redefine a preprocessing symbol, associated with value.
2667 -- If "=value" is not specified, then the value of the symbol is True.
2668 -- A symbol is an identifier, following normal Ada (case-insensitive)
2669 -- rules for its syntax, and value is any sequence (including an empty
2670 -- sequence) of characters from the set (letters, digits, period,
2671 -- underline). Ada reserved words may be used as symbols, with the
2672 -- exceptions of "if", "else", "elsif", "end", "and", "or" and "then".
2673 --
2674 -- A symbol declared with this qualifier on the command line replaces
2675 -- a symbol with the same name either in a definition file or specified
2676 -- with a switch -D in the preprocessor data file.
2677 --
2678 -- This qualifier is similar to qualifier /ASSOCIATE of
2679 -- GNAT PREPROCESSING.
2683 -- /NOSYNTAX_ONLY (D)
2684 -- /SYNTAX_ONLY
2685 --
2686 -- Run GNAT in syntax checking only mode. You can check a series of
2687 -- files in a single command, and can use wild cards to specify such a
2688 -- group of files.
2689 --
2690 -- You may use other qualifiers in conjunction with this qualifier. In
2691 -- particular, /LIST and /REPORT_ERRORS=VERBOSE are useful to control the
2692 -- format of any generated error messages.
2693 --
2694 -- The output is simply the error messages, if any. No object file or ALI
2695 -- file is generated by a syntax-only compilation. Also, no units other
2696 -- than the one specified are accessed. For example, if a unit "X" with's
2697 -- a unit "Y", compiling unit "X" in syntax check only mode does not
2698 -- access the source file containing unit "Y".
2699 --
2700 -- Normally, GNAT allows only a single unit in a source file. However,
2701 -- this restriction does not apply in syntax-check-only mode, and it is
2702 -- possible to check a file containing multiple compilation units
2703 -- concatenated together. This is primarily used by the GNAT CHOP
2704 -- command.
2708 -- /TABLE_MULTIPLIER=nnn
2709 --
2710 -- All compiler tables start at nnn times usual starting size.
2714 -- /TRACE_UNITS
2715 -- /NOTRACE_UNITS
2716 --
2717 -- This switch that does for the frontend what /VERBOSE does for the
2718 -- backend. The system prints the name of each unit, either a compilation
2719 -- unit or nested unit, as it is being analyzed.
2723 -- /TREE_OUTPUT
2724 -- /NOTREE_OUTPUT
2725 --
2726 -- Cause GNAT to write the internal tree for a unit to a file (with the
2727 -- filetype ATB for a body or ATS for a spec). This is not normally
2728 -- required, but is used by separate analysis tools. Typically these
2729 -- tools do the necessary compilations automatically, so you should never
2730 -- have to specify this switch in normal operation.
2734 -- /TRY_SEMANTICS
2735 -- /NOTRY_SEMANTICS
2736 --
2737 -- In normal operation mode the compiler first parses the program and
2738 -- determines if there are any syntax errors. If there are, appropriate
2739 -- error messages are generated and compilation is immediately
2740 -- terminated. This qualifier tells GNAT to continue with semantic
2741 -- analysis even if syntax errors have been found. This may enable the
2742 -- detection of more errors in a single run. On the other hand, the
2743 -- semantic analyzer is more likely to encounter some internal fatal
2744 -- error when given a syntactically invalid tree.
2748 -- /NOUNITS_LIST (D)
2749 -- /UNITS_LIST
2750 --
2751 -- Print a list of units required by this compilation on SYS$OUTPUT. The
2752 -- listing includes all units on which the unit being compiled depends
2753 -- either directly or indirectly.
2757 -- /NOUNIQUE_ERROR_TAG (D)
2758 -- /UNIQUE_ERROR_TAG
2759 --
2760 -- Tag compiler error messages with the string "error: ".
2764 -- /NOUPPERCASE_EXTERNALS (D)
2765 -- /UPPERCASE_EXTERNALS
2766 --
2767 -- Fold default and explicit external names in pragmas Import and Export
2768 -- to uppercase for compatibility with the default behavior of DEC C.
2819 -- /VALIDITY_CHECKING[=(keyword,[...])]
2820 --
2821 -- Control level of validity checking.
2822 --
2823 -- DEFAULT (D) In this mode checks are made to prevent
2824 -- erroneous behavior in accordance with the RM.
2825 -- Notably extra checks may be needed for case
2826 -- statements and subscripted array assignments.
2827 --
2828 -- NONE No special checks for invalid values are
2829 -- performed. This means that references to
2830 -- uninitialized variables can cause erroneous
2831 -- behavior from constructs like case statements
2832 -- and subscripted array assignments. In this
2833 -- mode, invalid values can lead to erroneous
2834 -- behavior.
2835 --
2836 -- FULL Every assignment is checked for validity, so
2837 -- that it is impossible to assign invalid values.
2838 -- The RM specifically allows such assignments,
2839 -- but in this mode, invalid values can never be
2840 -- assigned, and an attempt to perform such an
2841 -- assignment immediately raises Constraint_Error.
2842 -- This behavior is allowed (but not required) by
2843 -- the RM. This mode is intended as a debugging aid,
2844 -- and may be useful in helping to track down
2845 -- uninitialized variables. It may be useful to
2846 -- use this in conjunction with the Normalize_Scalars
2847 -- pragma which attempts to initialize with invalid
2848 -- values where possible.
2852 -- /VERBOSE
2853 -- /NOVERBOSE
2854 --
2855 -- Show commands generated by the GCC driver. Normally used only for
2856 -- debugging purposes or if you need to be sure what version of the
2857 -- compiler you are executing.
2861 -- /NOASM (D)
2862 -- /ASM
2863 --
2864 -- Use to cause the assembler source file to be generated, using S as the
2865 -- filetype, instead of the object file. This may be useful if you need
2866 -- to examine the generated assembly code.
3019 -- /NOWARNINGS
3020 --
3021 -- Suppress the output of all warning messages from the GNAT front end.
3022 -- Note that it does not suppress warnings from the gcc back end.
3023 --
3024 -- /WARNINGS[=(keyword[,...])]
3025 --
3026 -- In addition to error messages, corresponding to illegalities as
3027 -- defined in the reference manual, the compiler detects two kinds of
3028 -- warning situations. First, the compiler considers some constructs
3029 -- suspicious and generates a warning message to alert you to a possible
3030 -- error. Second, if the compiler detects a situation that is sure to
3031 -- raise an exception at runtime, it generates a warning message.
3032 --
3033 -- You may specify the following keywords to change this behavior:
3034 --
3035 -- DEFAULT (D) The default behavior above.
3036 --
3037 -- ALL Activate all optional warnings.
3038 -- Activates most optional warning messages,
3039 -- see remaining list in this section for
3040 -- details on optional warning messages that
3041 -- can be individually controlled.
3042 -- The warnings that are not turned on by
3043 -- this option are BIASED_ROUNDING,
3044 -- IMPLICIT_DEREFERENCE, HIDING and
3045 -- ELABORATION. All other optional Ada
3046 -- warnings are turned on.
3047 --
3048 -- EVERY Activate every optional warning.
3049 -- Activates all optional warnings, including
3050 -- those listed above as exceptions for ALL.
3051 --
3052 -- NOALL Suppress all optional errors.
3053 -- Suppresses all optional warning messages
3054 -- that can be activated by option ALL.
3055 --
3056 -- ALL_GCC Request additional messages from the GCC
3057 -- backend. Most of these are not relevant
3058 -- to Ada.
3059 --
3060 -- CONDITIONALS Activate warnings for conditional
3061 -- Expressions used in tests that are known
3062 -- to be True or False at compile time. The
3063 -- default is that such warnings are not
3064 -- generated.
3065 --
3066 -- NOCONDITIONALS Suppress warnings for conditional
3067 -- expressions used in tests that are known
3068 -- to be True or False at compile time.
3069 --
3070 -- IMPLICIT_DEREFERENCE Activate warnings on implicit dereferencing.
3071 -- The use of a prefix of an access type in an
3072 -- indexed component, slice, or selected component
3073 -- without an explicit .all will generate
3074 -- a warning. With this warning enabled, access
3075 -- checks occur only at points where an explicit
3076 -- .all appears in the source code (assuming no
3077 -- warnings are generated as a result of this
3078 -- option). The default is that such warnings are
3079 -- not generated. Note that /WARNINGS=ALL does not

3081 --
3082 -- NOIMPLICIT_DEREFERENCE Suppress warnings on implicit dereferencing.
3083 -- in indexed components, slices, and selected
3084 -- components.
3085 --
3086 -- ELABORATION Activate warnings on missing pragma
3087 -- Elaborate_All statements. The default is
3088 -- that such warnings are not generated.
3089 --
3090 -- NOELABORATION Suppress warnings on missing pragma
3091 -- Elaborate_All statements.
3092 --
3093 -- ERRORS Warning messages are to be treated as errors.
3094 -- The warning string still appears, but the
3095 -- warning messages are counted as errors, and
3096 -- prevent the generation of an object file.
3097 --
3098 -- HIDING Activate warnings on hiding declarations.
3099 -- A declaration is considered hiding if it is
3100 -- for a non-overloadable entity, and it declares
3101 -- an entity with the same name as some other
3102 -- entity that is directly or use-visible. The
3103 -- default is that such warnings are not
3104 -- generated.
3105 --
3106 -- NOHIDING Suppress warnings on hiding declarations.
3107 --
3108 -- IMPLEMENTATION Activate warnings for a with of an internal
3109 -- GNAT implementation unit, defined as any unit
3110 -- from the Ada, Interfaces, GNAT, DEC or
3111 -- System hierarchies that is not documented in
3112 -- either the Ada Reference Manual or the GNAT
3113 -- Programmer's Reference Manual. Such units are
3114 -- intended only for internal implementation
3115 -- purposes and should not be with'ed by user
3116 -- programs. The default is that such warnings
3117 -- are generated.
3118 --
3119 -- NOIMPLEMENTATION Disables warnings for a with of an internal
3120 -- GNAT implementation unit.
3121 --
3122 -- INEFFECTIVE_INLINE Activate warnings on ineffective pragma Inlines
3123 -- Activates warnings for failure of front end
3124 -- inlining (activated by /INLINE=FULL) to inline
3125 -- a particular call. There are many reasons for
3126 -- not being able to inline a call, including most
3127 -- commonly that the call is too complex to
3128 -- inline. This warning can also be turned on
3129 -- using /INLINE=FULL.
3130 --
3131 -- NOINEFFECTIVE_INLINE Suppress warnings on ineffective pragma Inlines
3132 -- Suppresses warnings on ineffective pragma
3133 -- Inlines. If the inlining mechanism cannot
3134 -- inline a call, it will simply ignore the
3135 -- request silently.
3136 --
3137 -- MISSING_COMPONENT_CLAUSES
3138 -- Activate warnings for cases when there are
3139 -- component clauses for a record type, but not
3140 -- for every component of the record.
3141 --
3142 -- NOMISSING_COMPONENT_CLAUSES
3143 -- Suppress warnings for cases when there are
3144 -- missing component clauses for a record type.
3145 --
3146 -- MISSING_PARENS
3147 -- Activate warnings for cases where parentheses
3148 -- are not used and the result is potential
3149 -- ambiguity from a reader's point of view.
3150 -- For example (not a > b) when a and b are
3151 -- modular means (not (a) > b) and very likely
3152 -- the programmer intended (not (a > b)).
3153 --
3154 -- NOMISSING_PARENS
3155 -- Suppress warnings for cases where parentheses
3156 -- are not used and the result is potential
3157 -- ambiguity from a reader's point of view.
3158 --
3159 -- MODIFIED_UNREF Activates warnings for variables that are
3160 -- assigned (using an initialization value or with
3161 -- one or more assignment statements) but whose
3162 -- value is never read. The warning is suppressed
3163 -- for volatile variables and also for variables
3164 -- that are renamings of other variables or for
3165 -- which an address clause is given. This warning
3166 -- can also be turned on using /WARNINGS/OPTIONAL.
3167 --
3168 -- NOMODIFIED_UNREF Disables warnings for variables that are
3169 -- assigned or initialized, but never read.
3170 --
3171 -- NORMAL Sets normal warning mode, in which enabled
3172 -- warnings are issued and treated as warnings
3173 -- rather than errors. This is the default mode.
3174 -- It can be used to cancel the effect of an
3175 -- explicit /WARNINGS=SUPPRESS or
3176 -- /WARNINGS=ERRORS. It also cancels the effect
3177 -- of the implicit /WARNINGS=ERRORS that is
3178 -- activated by the use of /STYLE=GNAT.
3179 --
3180 -- OBSOLESCENT Activates warnings for calls to subprograms
3181 -- marked with pragma Obsolescent and for use of
3182 -- features in Annex J of the Ada Reference
3183 -- Manual. In the case of Annex J, not all
3184 -- features are flagged. In particular use of the
3185 -- renamed packages (like Text_IO), use of package
3186 -- ASCII and use of the attribute 'Constrained are
3187 -- not flagged, since these are very common and
3188 -- would generate many annoying positive warnings.

3316 -- /NOWIDE_CHARACTER_ENCODING (D)
3317 -- /WIDE_CHARACTER_ENCODING[=encode-type]
3318 --
3319 -- Specifies the mechanism used to encode wide characters. 'encode-type'
3320 -- is one of the following:
3321 --
3322 -- BRACKETS (D) A wide character is encoded as ["xxxx"] where XXXX
3323 -- are four hexadecimal digits representing the coding
3324 -- ('Pos value) of the character in type
3325 -- Wide_Character. The hexadecimal digits may use upper
3326 -- or lower case letters.
3327 --
3328 -- This notation can also be used for upper half
3329 -- Character values using the format ["xx"] where XX is
3330 -- two hexadecimal digits representing the coding ('Pos
3331 -- value) of the character in type Character (or
3332 -- Wide_Character). The hexadecimal digits may use upper
3333 -- of lower case.
3334 --
3335 -- NONE No wide characters are allowed. Same
3336 -- as /NOWIDE_CHARACTER_ENCODING.
3337 --
3338 -- HEX In this encoding, a wide character is represented by
3339 -- the following five character sequence: ESC a b c d
3340 -- Where 'a', 'b', 'c', and 'd' are the four hexadecimal
3341 -- characters (using uppercase letters) of the wide
3342 -- character code. For example, ESC A345 is used to
3343 -- represent the wide character with code 16#A345#. This
3344 -- scheme is compatible with use of the full
3345 -- Wide_Character set.
3346 --
3347 -- UPPER The wide character with encoding 16#abcd# where the
3348 -- upper bit is on (in other words, "a" is in the range
3349 -- 8-F) is represented as two bytes, 16#ab# and 16#cd#.
3350 -- The second byte may never be a format control
3351 -- character, but is not required to be in the upper
3352 -- half. This method can be also used for shift-JIS or
3353 -- EUC, where the internal coding matches the external
3354 -- coding.
3355 --
3356 -- SHIFT_JIS A wide character is represented by a two-character
3357 -- sequence, 16#ab# and 16#cd#, with the restrictions
3358 -- described for upper-half encoding as described above.
3359 -- The internal character code is the corresponding JIS
3360 -- character according to the standard algorithm for
3361 -- Shift-JIS conversion. Only characters defined in the
3362 -- JIS code set table can be used with this encoding
3363 -- method.
3364 --
3365 -- UTF8 A wide character is represented using
3366 -- UCS Transformation Format 8 (UTF-8) as defined in Annex
3367 -- R of ISO 10646-1/Am.2. Depending on the character
3368 -- value, the representation is a one, two, or three byte
3369 -- sequence:
3370 --
3371 -- 16#0000#-16#007f#: 2#0xxxxxxx#
3372 -- 16#0080#-16#07ff#: 2#110xxxxx# 2#10xxxxxx#
3373 -- 16#0800#-16#ffff#: 2#1110xxxx# 2#10xxxxxx# 2#10xxxxxx#
3374 --
3375 -- where the xxx bits correspond to the left-padded bits
3376 -- of the 16-bit character value. Note that all lower
3377 -- half ASCII characters are represented as ASCII bytes
3378 -- and all upper half characters and other wide characters
3379 -- are represented as sequences of upper-half (The full
3380 -- UTF-8 scheme allows for encoding 31-bit characters as
3381 -- 6-byte sequences, but in this implementation, all UTF-8
3382 -- sequences of four or more bytes length will be treated
3383 -- as illegal).
3384 --
3385 -- EUC A wide character is represented by a two-character
3386 -- sequence 16#ab# and 16#cd#, with both characters being
3387 -- in the upper half. The internal character code is the
3388 -- corresponding JIS character according to the EUC
3389 -- encoding algorithm. Only characters defined in the JIS
3390 -- code set table can be used with this encoding method.
3394 -- NODOC (see /WIDE_CHARACTER_ENCODING)
3398 -- /NOXDEBUG (D)
3399 -- /XDEBUG
3400 --
3401 -- Output expanded source files for source level debugging.
3402 -- The expanded source (see /EXPAND_SOURCE) is written to files
3403 -- with names formed by appending "_DG" to the input file name,
3404 -- The debugging information generated by the /DEBUG qualifier will then
3405 -- refer to the generated file. This allows source level debugging using
3406 -- the generated code which is sometimes useful for complex code, for
3407 -- example to find out exactly which part of a complex construction
3408 -- raised an exception. The maximum line length for the output is 72.

3422 -- the output.
3429 -- /XREF[=keyword]
3430 --
3431 -- Normally the compiler generates full cross-referencing information in
3432 -- the .ALI file. This information is used by a number of tools,

4387 -- Switches for GNAT MAKE --
4388 ----------------------------
4397 -- /ACTIONS=(keyword[,...])
4398 --
4399 -- GNAT MAKE default behavior is to check if the sources are up to date,
4400 -- compile those sources that are not up to date, bind the main source,
4401 -- then link the executable.
4402 --
4403 -- With the /ACTIONS qualifier, GNAT MAKE may be restricted to one or
4404 -- two of these three steps:
4405 --
4406 -- o Compile
4407 -- o Bind
4408 -- o Link
4409 --
4410 --
4411 -- You may specify one or more of the following keywords to the /ACTIONS
4412 -- qualifier:
4413 --
4414 -- BIND Bind only. Can be combined with /ACTIONS=COMPILE
4415 -- to do compilation and binding, but no linking.
4416 -- Can be combined with /ACTIONS=LINK to do binding and
4417 -- linking. When not combined with /ACTIONS=COMPILE,
4418 -- all the units in the closure of the main program must
4419 -- have been previously compiled and must be up to date.
4420 --
4421 -- COMPILE Compile only. Do not perform binding, except when
4422 -- /ACTIONS=BIND is also specified. Do not perform
4423 -- linking, except if both /ACTIONS=BIND and /ACTIONS=LINK
4424 -- are also specified.
4425 --
4426 -- LINK Link only. Can be combined with /ACTIONS=BIND to do
4427 -- binding and linking. Linking will not be performed
4428 -- if combined with /ACTIONS=COMPILE but not with
4429 -- /ACTIONS=BIND\. When not combined with /ACTIONS=BIND
4430 -- all the units in the closure of the main program must
4431 -- have been previously compiled and must be up to date,
4432 -- and the main program need to have been bound.
4436 -- /ADD_PROJECT_SEARCH_PATH=(directory[,...])
4437 --
4438 -- Add directories to the project search path.
4442 -- /NOALL_FILES (D)
4443 -- /ALL_FILES
4444 --
4445 -- Consider all files in the make process, even the GNAT internal system
4446 -- files (for example, the predefined Ada library files). By default,
4447 -- GNAT MAKE does not check these files (however, if there is an
4448 -- installation problem, it will be caught when GNAT MAKE binds your
4449 -- program). You may have to specify this qualifier if you are working on
4450 -- GNAT itself. The vast majority of GNAT MAKE users never need to
4451 -- specify this switch. All GNAT internal files with will be compiled
4452 -- with /STYLE_CHECK=GNAT.
4456 -- /NOALL_PROJECTS (D)
4457 -- /ALL_PROJECTS
4458 --
4459 -- Implies /Unique.
4460 -- When used without project files, it is equivalent to /UNIQUE.
4461 -- When used with a project file with no main (neither on the command
4462 -- line nor in the attribute Main) check every source of every project,
4463 -- recompile all sources that are not up to date and rebuild libraries
4464 -- if necessary.
4468 -- /BINDER_QUALIFIERS
4469 --
4470 -- Any qualifiers specified after this qualifier other than
4471 -- /COMPILER_QUALIFIERS, /LINKER_QUALIFIERS and /MAKE_QUALIFIERS will be
4472 -- passed to any GNAT BIND commands generated by GNAT MAKE.
4476 -- /BND_LNK_FULL_PROJECT
4477 --
4478 -- Bind and link all sources of a project, without any consideration
4479 -- to attribute Main, if there is one. This qualifier need to be
4480 -- used in conjunction with the /PROJECT_FILE= qualifier and cannot
4481 -- be used with a main subprogram on the command line or for
4482 -- a library project file. As the binder is invoked with the option
4483 -- meaning "No Ada main subprogram", the user must ensure that the
4484 -- proper options are specified to the linker. This qualifier is
4485 -- normally used when the main subprogram is in a foreign language
4486 -- such as C.
4490 -- /COMPILER_QUALIFIERS
4491 --
4492 -- Any qualifiers specified after this qualifier other than
4493 -- /BINDER_QUALIFIERS, /LINKER_QUALIFIERS and /MAKE_QUALIFIERS will be
4494 -- passed to any GNAT COMPILE commands generated by GNAT MAKE.
4498 -- /CONDITIONAL_SOURCE_SEARCH=dir
4499 --
4500 -- Equivalent to "/SOURCE_SEARCH=dir /SKIP_MISSING=dir".
4504 -- /NOCONTINUE_ON_ERROR (D)
4505 -- /CONTINUE_ON_ERROR
4506 --
4507 -- Keep going. Continue as much as possible after a compilation error.
4508 -- To ease the programmer's task in case of compilation errors, the list
4509 -- of sources for which the compile fails is given when GNAT MAKE
4510 -- terminates.
4514 -- /CURRENT_DIRECTORY (D)
4515 -- /NOCURRENT_DIRECTORY
4516 --
4517 -- Look for source, library or object files in the default directory.
4521 -- /NODEPENDENCIES_LIST (D)
4522 -- /DEPENDENCIES_LIST
4523 --
4524 -- Check if all objects are up to date. If they are, output the object
4525 -- dependences to SYS$OUTPUT in a form that can be directly exploited in
4526 -- a Unix-style Makefile. By default, each source file is prefixed with
4527 -- its (relative or absolute) directory name. This name is whatever you
4528 -- specified in the various /SOURCE_SEARCH and /SEARCH qualifiers. If
4529 -- you also specify the /QUIET qualifier, only the source file names,
4530 -- without relative paths, are output. If you just specify the
4531 -- /DEPENDENCY_LIST qualifier, dependencies of the GNAT internal system
4532 -- files are omitted. This is typically what you want. If you also
4533 -- specify the /ALL_FILES qualifier, dependencies of the GNAT internal
4534 -- files are also listed. Note that dependencies of the objects in
4535 -- external Ada libraries (see the /SKIP_MISSING qualifier) are never
4536 -- reported.
4540 -- /DIRECTORY_OBJECTS=<file>
4541 --
4542 -- Put all object files and .ALI files in <file>.
4543 -- This qualifier is not compatible with /PROJECT_FILE.
4547 -- /NOPLAY_PROGRESS (D)
4548 -- /DISPLAY_PROGRESS
4549 --
4550 -- Display progress for each source, up to date or not, as a single line
4551 -- completed x out of y (zz%)
4552 -- If the file needs to be compiled this is displayed after the
4553 -- invocation of the compiler. These lines are displayed even in quiet
4554 -- output mode (/QUIET).
4558 -- /NODO_OBJECT_CHECK (D)
4559 -- /DO_OBJECT_CHECK
4560 --
4561 -- Don't compile, bind, or link. Output a single command that will
4562 -- recompile an out of date unit, if any. Repeated use of this option,
4563 -- followed by carrying out the indicated compilation, will eventually
4564 -- result in recompiling all required units.
4565 --
4566 -- If any ALI is missing during the process, GNAT MAKE halts and
4567 -- displays an error message.
4571 -- /EXECUTABLE=exec-name
4572 --
4573 -- The name of the final executable program will be 'exec_name'. If this
4574 -- qualifier is omitted the default name for the executable will be the
4575 -- name of the input file with an EXE filetype. You may prefix
4576 -- 'exec_name' with a relative or absolute directory path.
4580 -- /EXTERNAL_REFERENCE="name=val"
4581 --
4582 -- Specifies an external reference to the project manager. Useful only if

4592 --
4593 -- Follow links when parsing project files
4597 -- /NOFORCE_COMPILE (D)
4598 -- /FORCE_COMPILE
4599 --
4600 -- Force recompilations. Recompile all sources, even though some object
4601 -- files may be up to date, but don't recompile predefined or GNAT
4602 -- internal files unless the /ALL_FILES qualifier is also specified.
4606 -- /NOFULL_PATH_IN_BRIEF_MESSAGES (D)
4607 -- /FULL_PATH_IN_BRIEF_MESSAGES
4608 --
4609 -- When using project files, if some errors or warnings are detected
4610 -- during parsing and verbose mode is not in effect (no use of qualifier
4611 -- /VERBOSE), then error lines start with the full path name of the
4612 -- project file, rather than its simple file name.
4616 -- /NOHIGH_VERBOSITY (D)
4617 -- /HIGH_VERBOSITY
4618 --
4619 -- Displays the reason for all recompilations GNAT MAKE decides are
4620 -- necessary, in high verbosity. Equivalent to /VERBOSE.
4624 -- /NOIN_PLACE (D)
4625 -- /IN_PLACE
4626 --
4627 -- In normal mode, GNAT MAKE compiles all object files and ALI files
4628 -- into the current directory. If the /IN_PLACE switch is used,
4629 -- then instead object files and ALI files that already exist are over-
4630 -- written in place. This means that once a large project is organized
4631 -- into separate directories in the desired manner, then GNAT MAKE will
4632 -- automatically maintain and update this organization. If no ALI files
4633 -- are found on the Ada object path, the new object and ALI files are
4634 -- created in the directory containing the source being compiled.
4638 -- /SOURCE_INDEX=nnn
4639 --
4640 -- Specifies the index of the units in the source file
4641 -- By default, source files are mono-unit and there is no index
4642 -- When /SOURCE_INDEX=nnn is specified, only one main may be specified
4643 -- on the command line.
4647 -- /LIBRARY_SEARCH=(directory[,...])
4648 --
4649 -- Add the specified directories to the list of directories in which the
4650 -- linker will search for libraries.
4654 -- /LINKER_QUALIFIERS
4655 --
4656 -- Any qualifiers specified after this qualifier other than
4657 -- /COMPILER_QUALIFIERS, /BINDER_QUALIFIERS and /MAKE_QUALIFIERS will be
4658 -- passed to any GNAT LINK commands generated by GNAT LINK.
4662 -- /NOLOW_VERBOSITY (D)
4663 -- /LOW_VERBOSITY
4664 --
4665 -- Displays the reason for all recompilations GNAT MAKE decides are
4666 -- necessary, in low verbosity, that is with less output than
4667 -- /MEDIUM_VERBOSITY, /HIGH_VERBOSITY or /VERBOSE.
4671 -- /MAKE_QUALIFIERS
4672 --
4673 -- Any qualifiers specified after this qualifier other than
4674 -- /COMPILER_QUALIFIERS, /BINDER_QUALIFIERS and /LINKER_QUALIFIERS
4675 -- are for the benefit of GNAT MAKE itself.
4679 -- /NOMAPPING (D)
4680 -- /MAPPING
4681 --
4682 -- Use a mapping file. A mapping file is a way to communicate to the
4683 -- compiler two mappings: from unit names to file names (without any
4684 -- directory information) and from file names to path names (with full
4685 -- directory information). These mappings are used by the compiler to
4686 -- short-circuit the path search. When GNAT MAKE is invoked with this
4687 -- qualifier, it will create a mapping file, initially populated by the
4688 -- project manager, if /PROJECT_File= is used, otherwise initially empty.
4689 -- Each invocation of the compiler will add the newly accessed sources to
4690 -- the mapping file. This will improve the source search during the next
4691 -- invocations of the compiler
4695 -- /NOMEDIUM_VERBOSITY (D)
4696 -- /MEDIUM_VERBOSITY
4697 --
4698 -- Displays the reason for all recompilations GNAT MAKE decides are
4699 -- necessary, in medium verbosity, that is with potentially less output
4700 -- than /HIGH_VERBOSITY or /VERBOSE.
4709 -- /MESSAGES_PROJECT_FILE[=messages-option]
4710 --
4711 -- Specifies the "verbosity" of the parsing of project files.
4712 -- messages-option may be one of the following:
4713 --
4714 -- DEFAULT (D) No messages are output if there is no error or warning.
4715 --
4716 -- MEDIUM A small number of messages are output.
4717 --
4718 -- HIGH A great number of messages are output, most of them not
4719 -- being useful for the user.
4723 -- /NOMINIMAL_RECOMPILATION (D)
4724 -- /MINIMAL_RECOMPILATION
4725 --
4726 -- Specifies that the minimum necessary amount of recompilation
4727 -- be performed. In this mode GNAT MAKE ignores time stamp differences
4728 -- when the only modifications to a source file consist in
4729 -- adding/removing comments, empty lines, spaces or tabs.
4733 -- /NOCREATE_MISSING_DIRS (D)
4734 -- /CREATE_MISSING_DIRS
4735 --
4736 -- When an object directory, a library directory or an exec directory
4737 -- in missing, attempt to create the directory.
4741 -- /NOLINK
4742 --
4743 -- Compile only. Do not perform binding and linking. If the root unit is
4744 -- not a main unit, this is the default. Otherwise GNAT MAKE will
4745 -- attempt binding and linking unless all objects are up to date and the
4746 -- executable is more recent than the objects.
4747 -- This is equivalent to /ACTIONS=COMPILE
4751 -- /NOMAIN
4752 --
4753 -- No main subprogram. Bind and link the program even if the unit name
4754 -- given on the command line is a package name. The resulting executable
4755 -- will execute the elaboration routines of the package and its closure,
4756 -- then the finalization routines.
4760 -- /NON_PROJECT_UNIT_COMPILATION
4761 --
4762 -- Normally, when using project files, a unit that is not part of any
4763 -- project file, cannot be compile. These units may be compile, when

5760 --
5761 -- The difference between "GNAT style comment line indentation" and
5762 -- "standard comment line indentation" is the following: for standard
5763 -- comment indentation, any comment line is indented as if it were
5764 -- a declaration or statement at the same place.
5765 -- For GNAT style comment indentation, comment lines which are
5766 -- immediately followed by if or case statement alternative, record
5767 -- variant or 'begin' keyword are indented as the keyword that follows
5768 -- them.:
5769 --
5770 -- Standard indentation:
5771 --
5772 -- if A then
5773 -- null;
5774 -- -- some comment
5775 -- else
5776 -- null;
5777 -- end if;
5778 --
5779 -- GNAT style indentation:
5780 --
5781 -- if A then
5782 -- null;
5783 -- -- some comment
5784 -- else
5785 -- null;
5786 -- end if;
5787 --
5788 -- Option "GNAT style comment beginning" means that for each comment
5789 -- which is not considered as non-formattable separator (that is, the
5790 -- comment line contains only dashes, or a comment line ends with two
5791 -- dashes), there will be at least two spaces between starting "--" and
5792 -- the first non-blank character of the comment.
5796 -- /CONFIGURATION_PRAGMAS_FILE=file
5797 --
5798 -- Specify a configuration pragmas file that need to be passed to the
5799 -- compiler.
5808 -- /CONSTRUCT_LAYOUT[=construct-option]
5809 --
5810 -- Set construct layout. Default is GNAT style layout.
5811 -- construct-option may be one of the following:
5812 --
5813 -- GNAT (D)
5814 -- COMPACT
5815 -- UNCOMPACT
5816 --
5817 -- The difference between GNAT style and Compact layout on one hand
5818 -- and Uncompact layout on the other hand can be illustrated by the
5819 -- following examples:
5820 --
5821 -- GNAT style and Uncompact layout
5822 -- Compact layout
5823 --
5824 -- type q is record type q is
5825 -- a : integer; record
5826 -- b : integer; a : integer;
5827 -- end record; b : integer;
5828 -- end record;
5829 --
5830 --
5831 -- Block : declare Block :
5832 -- A : Integer := 3; declare
5833 -- begin A : Integer := 3;
5834 -- Proc (A, A); begin
5835 -- end Block; Proc (A, A);
5836 -- end Block;

5839 -- A (J) := 0; for J in 1 .. 10 loop
5840 -- end loop Clear; A (J) := 0;
5841 -- end loop Clear;
5842 --
5843 --
5844 -- A further difference between GNAT style layout and compact layout is
5845 -- that in GNAT style layout compound statements, return statements and
5846 -- bodies are always separated by empty lines.
5850 -- /CONTINUATION_INDENT=nnn
5851 --
5852 -- Indentation level for continuation lines, nnn from 1 .. 9.
5853 -- The default value is one less then the (normal) indentation level,

5893 -- /STMT_NAME_ON_NEW_LINE
5894 --
5895 -- For named block and loop statements use a separate line for the
5896 -- statement name, but do not use an extra indentation level for the
5897 -- statement itself.
5908 -- /END_OF_LINE=[option]
5909 --
5910 -- Specifies the form of the line terminators in the produced source.
5911 -- By default, the form of the line terminator depends on the platforms.
5912 -- On Unix and VMS, it is a Line Feed (LF) character. On Windows (DOS),
5913 -- It is a Carriage Return (CR) followed by a Line Feed.
5914 -- The Options DOS and CRLF are equivalent. The options UNIX and LF are
5915 -- also equivalent.
5919 -- /EXTERNAL_REFERENCE="name=val"
