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

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.

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.

1064 -- Switches for GNAT COMPILE --
1065 -------------------------------
1069 -- /NO83 (D)
1070 -- /83
1071 --
1072 -- Although GNAT is primarily an Ada 95 compiler, it accepts this
1073 -- qualifier to specify that an Ada 83 mode program is being compiled. If
1074 -- you specify this qualifier, GNAT rejects Ada 95 extensions and applies
1075 -- Ada 83 semantics. It is not possible to guarantee this qualifier does
1076 -- a perfect job; for example, some subtle tests of pathological cases,
1077 -- such as are found in ACVC tests that have been removed from the ACVC
1078 -- suite for Ada 95, may not compile correctly. However for practical
1079 -- purposes, using this qualifier should ensure that programs that
1080 -- compile correctly under the /83 qualifier can be ported reasonably
1081 -- easily to an Ada 83 compiler. This is the main use of this qualifier.
1082 --
1083 -- With few exceptions (most notably the need to use "<>" on
1084 -- unconstrained generic formal parameters), it is not necessary to use
1085 -- this qualifier switch when compiling Ada 83 programs, because, with
1086 -- rare and obscure exceptions, Ada 95 is upwardly compatible with Ada
1087 -- 83. This means that a correct Ada 83 program is usually also a correct
1088 -- Ada 95 program.
1092 -- /95 (D)
1093 --
1094 -- Allows GNAT to recognize the full range of Ada 95 constructs.
1095 -- This is the normal default for GNAT Pro.
1099 -- /05 (D)
1100 --
1101 -- Allows GNAT to recognize all implemented proposed Ada 2005
1102 -- extensions. See features file for list of implemented features.
1106 -- /NOASM (D)
1107 -- /ASM
1108 --
1109 -- Use to cause the assembler source file to be generated, using S as the
1110 -- filetype, instead of the object file. This may be useful if you need
1111 -- to examine the generated assembly code.
1128 -- /NOCHECKS
1129 -- /CHECKS[=(keyword[,...])]
1130 --
1131 -- If you compile with the default options, GNAT will insert many runtime
1132 -- checks into the compiled code, including code that performs range
1133 -- checking against constraints, but not arithmetic overflow checking for
1134 -- integer operations (including division by zero) or checks for access
1135 -- before elaboration on subprogram calls. All other runtime checks, as
1136 -- required by the Ada 95 Reference Manual, are generated by default.
1137 --
1138 -- You may specify one or more of the following keywords to the /CHECKS
1139 -- qualifier to modify this behavior:
1140 --
1141 -- DEFAULT The behavior described above. This is the default
1142 -- if the /CHECKS qualifier is not present on the
1143 -- command line. Same as /NOCHECKS.
1144 --
1145 -- OVERFLOW Enables overflow checking for integer operations and
1146 -- checks for access before elaboration on subprogram
1147 -- calls. This causes GNAT to generate slower and larger
1148 -- executable programs by adding code to check for both
1149 -- overflow and division by zero (resulting in raising
1150 -- "Constraint_Error" as required by Ada semantics).
1151 -- Similarly, GNAT does not generate elaboration check
1152 -- by default, and you must specify this keyword to
1153 -- enable them.
1154 --
1155 -- Note that this keyword does not affect the code
1156 -- generated for any floating-point operations; it
1157 -- applies only to integer operations. For floating-point,
1158 -- GNAT has the "Machine_Overflows" attribute set to
1159 -- "False" and the normal mode of operation is to generate
1160 -- IEEE NaN and infinite values on overflow or invalid
1161 -- operations (such as dividing 0.0 by 0.0).
1162 --
1163 -- ELABORATION Enables dynamic checks for access-before-elaboration
1164 -- on subprogram calls and generic instantiations.
1165 --
1166 -- ASSERTIONS The pragmas "Assert" and "Debug" normally have no
1167 -- effect and are ignored. This keyword causes "Assert"
1168 -- and "Debug" pragmas to be activated.
1169 --
1170 -- SUPPRESS_ALL Suppress all runtime checks as though you have "pragma
1171 -- Suppress (all_checks)" in your source. Use this switch
1172 -- to improve the performance of the code at the expense
1173 -- of safety in the presence of invalid data or program
1174 -- bugs.
1175 --
1176 -- DEFAULT Suppress the effect of any option OVERFLOW or
1177 -- ASSERTIONS.
1178 --
1179 -- FULL (D) Similar to OVERFLOW, but suppress the effect of any
1180 -- option ELABORATION or SUPPRESS_ALL.
1181 --
1182 -- These keywords only control the default setting of the checks. You
1183 -- may modify them using either "Suppress" (to remove checks) or
1184 -- "Unsuppress" (to add back suppressed checks) pragmas in your program
1185 -- source.
1189 -- NODOC (see /CHECKS)
1193 -- /NOCOMPRESS_NAMES (D)
1194 -- /COMPRESS_NAMES
1195 --
1196 -- Compress debug information and external symbol name table entries.
1197 -- In the generated debugging information, and also in the case of long
1198 -- external names, the compiler uses a compression mechanism if the name
1199 -- is very long. This compression method uses a checksum, and avoids
1200 -- trouble on some operating systems which have difficulty with very long
1201 -- names.
1205 -- /CONFIGURATION_PRAGMAS_FILE=file
1206 --
1207 -- Specify a configuration pragmas file that need to be taken into account
1211 -- /CURRENT_DIRECTORY (D)
1212 -- /NOCURRENT_DIRECTORY
1213 --
1214 -- Look for source files in the default directory.
1218 -- /DATA_PREPROCESSING=file_name
1219 --
1220 -- This qualifier indicates to the compiler the file name (without
1221 -- directory information) of the preprocessor data file to use.
1222 -- The preprocessor data file should be found in the source directories.
1223 --
1224 -- A preprocessing data file is a text file with significant lines
1225 -- indicating how should be preprocessed either a specific source or all
1226 -- sources not mentioned in other lines. A significant line is a non
1227 -- empty, non comment line. Comments are similar to Ada comments.
1228 --
1229 -- Each significant line starts with either a literal string or the
1230 -- character '*'. A literal string is the file name (without directory
1231 -- information) of the source to preprocess. A character '*' indicates the
1232 -- preprocessing for all the sources that are not specified explicitly on
1233 -- other lines. It is an error to have two lines with the same file name
1234 -- or two lines starting with the character '*'.
1235 --
1236 -- After the file name or the character '*', another optional literal
1237 -- string indicating the file name of the definition file to be used for
1238 -- preprocessing. (see 15.3 Form of Definitions File. The definition files
1239 -- are found by the compiler in one of the source directories. In some
1240 -- cases, when compiling a source in a directory other than the current
1241 -- directory, if the definition file is in the current directory, it may
1242 -- be necessary to add the current directory as a source directory through
1243 -- qualifier "/SEARCH=[]", otherwise the compiler would not find the
1244 -- definition file.
1245 --
1246 -- Then, optionally, switches similar to those of gnatprep may be found.
1247 -- Those switches are:
1248 --
1249 -- -b Causes both preprocessor lines and the lines deleted by
1250 -- preprocessing to be replaced by blank lines, preserving
1251 -- the line number. This switch is always implied;
1252 -- however, if specified after `-c' it cancels the effect
1253 -- of `-c'.
1254 --
1255 -- -c Causes both preprocessor lines and the lines deleted by
1256 -- preprocessing to be retained as comments marked with
1257 -- the special string "--! ".
1258 --
1259 -- -Dsymbol=value Define or redefine a symbol, associated with value.
1260 -- A symbol is an Ada identifier, or an Ada reserved word,
1261 -- with the exception of "if", "else", "elsif", "end",
1262 -- "and", "or" and "then". value is either a literal
1263 -- string, an Ada identifier or any Ada reserved word.
1264 -- A symbol declared with this switch replaces a symbol
1265 -- with the same name defined in a definition file.
1266 --
1267 -- -s Causes a sorted list of symbol names and values to be
1268 -- listed on the standard output file.
1269 --
1270 -- -u Causes undefined symbols to be treated as having the
1271 -- value FALSE in the context of a preprocessor test.
1272 -- In the absence of this option, an undefined symbol
1273 -- in a #if or #elsif test will be treated as an error.
1274 --
1275 -- Examples of valid lines in a preprocessor data file:
1276 --
1277 -- "toto.adb" "prep.def" -u
1278 -- -- preprocess "toto.adb", using definition file "prep.def",
1279 -- -- undefined symbol are False.
1280 --
1281 -- * -c -DVERSION=V101
1282 -- -- preprocess all other sources without a definition file;
1283 -- -- suppressed lined are commented; symbol VERSION has the value
1284 -- -- V101.
1285 --
1286 -- "titi.adb" "prep2.def" -s
1287 -- -- preprocess "titi.adb", using definition file "prep2.def";
1288 -- -- list all symbols with their values.
1303 -- /DEBUG[=debug-level]
1304 -- /NODEBUG
1305 --
1306 -- Specifies how much debugging information is to be included in
1307 -- the resulting object fie.
1308 --
1309 -- 'debug-level' is one of the following:
1310 --
1311 -- SYMBOLS (D) Include both debugger symbol records and traceback
1312 -- in the object file.
1313 --
1314 -- ALL Include debugger symbol records, traceback plus
1315 -- extra debug information in the object file.
1316 --
1317 -- NONE Excludes both debugger symbol records and traceback
1318 -- from the object file. Same as /NODEBUG.
1319 --
1320 -- TRACEBACK Includes only traceback records in the object
1321 -- file. This is the default when /DEBUG is not used.

1332 -- /NODISTRIBUTION_STUBS (D)
1333 -- /DISTRIBUTION_STUBS[=dist-opt]
1334 --
1335 -- 'dist-opt' is either RECEIVER (the default) or SENDER and indicates
1336 -- that stubs for use in distributed programs (see the Distributed

1341 -- NODOC (see /DISTRIBUTION_STUBS)
1345 -- /NOERROR_LIMIT (D)
1346 -- /ERROR_LIMIT=nnn
1347 --
1348 -- NNN is a decimal integer in the range of 1 to 999999 and limits the
1349 -- number of error messages to be generated to that number. Once that
1350 -- number has been reached, the compilation is abandoned.
1351 -- Specifying 999999 is equivalent to /NOERROR_LIMIT.
1355 -- NODOC (see /ERROR_LIMIT)
1359 -- /NOEXPAND_SOURCE (D)
1360 -- /EXPAND_SOURCE
1361 --
1362 -- Produces a listing of the expanded code in Ada source form. For

1390 -- name krunching.
1394 -- /NOFORCE_ALI (D)
1395 -- /FORCE_ALI
1396 --
1397 -- In normal operation mode, the .ALI file is not generated if any
1398 -- illegalities are detected in the program. The use of this qualifier
1399 -- forces generation of the .ALI file. This file is marked as being

1401 -- contain reasonably complete cross-reference information, and thus may
1402 -- be useful for use by tools (e.g. semantic browing tools or integrated
1403 -- development environments) that are driven from the .ALI file.
1407 -- /NOFULL_PATH_IN_BRIEF_MESSAGES (D)
1408 -- /FULL_PATH_IN_BRIEF_MESSAGES
1409 --
1410 -- When using project files, if some errors or warnings are detected

1456 --
1457 -- 1 The basic character set is Latin-1. This character
1458 -- set is defined by ISO standard 8859, part 1. The lower
1459 -- half (character codes 16#00# ... 16#7F#) is identical
1460 -- to standard ASCII coding, but the upper half is used
1461 -- to represent additional characters. This includes
1462 -- extended letters used by European languages, such as
1463 -- the umlaut used in German.
1464 --
1465 -- You may use any of these extended characters freely
1466 -- in character or string literals. In addition, the
1467 -- extended characters that represent letters can be
1468 -- used in identifiers.
1469 --
1470 -- 2 Latin-2 letters allowed in identifiers, with uppercase
1471 -- and lowercase equivalence.
1472 --
1473 -- 3 Latin-3 letters allowed in identifiers, with uppercase
1474 -- and lower case equivalence.
1475 --
1476 -- 4 Latin-4 letters allowed in identifiers, with uppercase
1477 -- and lower case equivalence.
1478 --
1479 -- PC IBM PC code page 437. This code page is the normal
1480 -- default for PCs in the U.S. It corresponds to the
1481 -- original IBM PC character set. This set has some, but
1482 -- not all, of the extended Latin-1 letters, but these
1483 -- letters do not have the same encoding as Latin-1. In
1484 -- this mode, these letters are allowed in identifiers
1485 -- with uppercase and lowercase equivalence.
1486 --
1487 -- PC850 This code page (850) is a modification of 437 extended
1488 -- to include all the Latin-1 letters, but still not with
1489 -- the usual Latin-1 encoding. In this mode, all these
1490 -- letters are allowed in identifiers with uppercase and
1491 -- lower case equivalence.
1492 --
1493 -- FULL_UPPER Any character in the range 80-FF allowed in

1496 -- equivalences in this range.
1497 --
1498 -- NO_UPPER No upper-half characters in the range 80-FF are

1528 -- /NOINLINE (D)
1529 -- /INLINE[=keyword]
1530 --
1531 -- Selects the level of inlining for your program. In the absence of this

1554 -- (/OPTIMIZE=SOME) or higher (/OPTIMIZE=UNROLL_LOOPS)
1555 -- levels of optimization.
1556 --
1557 -- FULL Front end inlining. The front end inlining activated
1558 -- by this switch is generally more extensive, and quite
1559 -- often more effective than the standard PRAGMA inlining
1560 -- mode. It will also generate additional dependencies.
1561 --
1562 -- SUPPRESS Suppresses all inlining, even if other optimization
1563 -- or inlining switches are set.
1567 -- NODOC (see /INLINE)
1572 -- /NO_INTERSPERSE_SOURCE (D)
1573 -- /INTERSPERSE_SOURCE
1574 --
1575 -- Causes output from /XDEBUG or /EXPAND_SOURCE to be interspersed with
1576 -- lines from the original source file, output as comment lines with the
1577 -- associated line number.
1582 -- /NO_JUSTIFY_MESSAGES (D)
1583 -- /JUSTIFY_MESSAGES=nnn
1584 --
1585 -- Causes error messages to be reformatted so that a message and all its
1586 -- continuation lines count as one warning or error in the statistics on
1587 -- total errors, and the message is broken down into lines (justified) so
1588 -- that no line is longer than nnn characters. The default message
1589 -- behavior (each message counted separately and not reformatted to fit
1590 -- a particular line length) can be obtained using /NO_JUSTIFY_MESSAGES.
1595 -- NODOC (see /JUSTIFY_MESSAGES)
1599 -- /MAX_LINE_LENGTH=nnn
1600 --
1601 -- Set maximum line length.
1602 -- The length of lines must not exceed the given value nnn.
1606 -- /NOLIST (D)
1607 -- /LIST
1608 --
1609 -- Cause a full listing of the file to be generated. In the case where
1610 -- a body is compiled, the corresponding spec is also listed, along
1611 -- with any subunits.
1615 -- /MAPPING_FILE=file_name
1616 --
1617 -- Use mapping file file_name
1618 --
1619 -- A mapping file is a way to communicate to the compiler two mappings:
1620 -- from unit names to file names (without any directory information) and
1621 -- from file names to path names (with full directory information).
1622 -- These mappings are used by the compiler to short-circuit the path
1623 -- search.
1624 --
1625 -- The use of mapping files is not required for correct operation of the
1626 -- compiler, but mapping files can improve efficiency, particularly when
1627 -- sources are read over a slow network connection. In normal operation,
1628 -- you need not be concerned with the format or use of mapping files,
1629 -- and /MAPPING_FILE is not a qualifier that you would use explicitly.
1630 -- It is intended only for use by automatic tools such as GNAT MAKE
1631 -- running under the project file facility. The description here of the
1632 -- format of mapping files is provided for completeness and for possible
1633 -- use by other tools.
1634 --
1635 -- A mapping file is a sequence of sets of three lines. In each set, the
1636 -- first line is the unit name, in lower case, with "%s" appended for
1637 -- specifications and "%b" appended for bodies; the second line is the
1638 -- file name; and the third line is the path name.
1639 --
1640 -- Example:
1641 --
1642 -- main%b
1643 -- main.2_ada
1644 -- /gnat/project1/sources/main.2_ada
1645 --
1646 -- When qualifier ?MAPPING_FILE is specified, the compiler will create in
1647 -- memory the two mappings from the specified file. If there is any
1648 -- problem (non existent file, truncated file or duplicate entries),
1649 -- no mapping will be created.
1650 --
1651 -- Several /MAPPING_FILE qualifiers may be specified; however, only the
1652 -- last one on the command line will be taken into account.
1653 --
1654 -- When using a project file, GNAT MAKE creates a temporary mapping file
1655 -- and communicates it to the compiler using this switch.
1664 -- /MESSAGES_PROJECT_FILE[=messages-option]
1665 --
1666 -- Specifies the "verbosity" of the parsing of project files.
1667 -- messages-option may be one of the following:
1668 --
1669 -- DEFAULT (D) No messages are output if there is no error or warning.
1670 --
1671 -- MEDIUM A small number of messages are output.
1672 --
1673 -- HIGH A great number of messages are output, most of them not
1674 -- being useful for the user.
1678 -- /MAX_NESTING=nnn
1679 --
1680 -- Set maximum level of nesting of constructs (including subprograms,
1681 -- loops, blocks, packages, and conditionals).
1682 -- The level of nesting must not exceed the given value nnn.
1683 -- A value of zero disable this style check (not enabled by default).
1687 -- /NO_GNAT_ADC
1688 --
1689 -- Cause the compiler to ignore any configuration pragmas file GNAT.ADC
1690 -- in the default directory. Implied by qualifier /PROJECT_FILE.
1691 -- Often used in conjunction with qualifier /CONFIGURATION_PRAGMAS_FILE.
1695 -- /NOLOAD
1696 --
1697 -- Cause the compiler to operate in semantic check mode with full
1698 -- checking for all illegalities specified in the reference manual, but
1699 -- without generation of any source code (no object or ALI file
1700 -- generated).
1701 --
1702 -- Since dependent files must be accessed, you must follow the GNAT
1703 -- semantic restrictions on file structuring to operate in this mode:
1704 --
1705 -- o The needed source files must be accessible.
1706 -- o Each file must contain only one compilation unit.
1707 -- o The file name and unit name must match.
1708 --
1709 -- The output consists of error messages as appropriate. No object file
1710 -- or ALI file is generated. The checking corresponds exactly to the
1711 -- notion of legality in the Ada reference manual.
1712 --
1713 -- Any unit can be compiled in semantics-checking-only mode, including
1714 -- units that would not normally be compiled (generic library units,
1715 -- subunits, and specifications where a separate body is present).
1719 -- /NOSTD_INCLUDES
1720 --
1721 -- Do not look in the default directory for source files of the runtime.
1725 -- /NOSTD_LIBRARIES
1726 --
1727 -- Do not look for library files in the system default directory.
1744 -- /NOOPTIMIZE (D)
1745 -- /OPTIMIZE[=(keyword[,...])]
1746 --
1747 -- Selects the level of optimization for your program. The supported
1748 -- keywords are as follows:
1749 --
1750 -- ALL (D) Perform most optimizations, including those that
1751 -- may be expensive.
1752 --
1753 -- NONE Do not do any optimizations. Same as /NOOPTIMIZE.
1754 --
1755 -- SOME Perform some optimizations, but omit ones that
1756 -- are costly in compilation time.
1757 --
1758 -- DEVELOPMENT Same as SOME.
1759 --
1760 -- INLINING Full optimization, and also attempt automatic inlining
1761 -- of small subprograms within a unit
1762 --
1763 -- UNROLL_LOOPS Try to unroll loops. This keyword may be specified
1764 -- with any keyword above other than NONE. Loop
1765 -- unrolling usually, but not always, improves the
1766 -- performance of programs.
1767 --
1768 -- NO_STRICT_ALIASING
1769 -- Suppress aliasing analysis. When optimization is
1770 -- enabled (ALL or SOME above), the compiler assumes
1771 -- that pointers do in fact point to legitimate values
1772 -- of the pointer type (allocated from the proper pool).
1773 -- If this assumption is violated, e.g. by the use of
1774 -- unchecked conversion, then it may be necessary to
1775 -- suppress this assumption using this keyword (which
1776 -- may be specified only in conjunction with any
1777 -- keyword above, other than NONE).
1781 -- NODOC (see /OPTIMIZE)
1785 -- /OUTPUT_FILE=fname
1786 --
1787 -- This has the same effect as /LIST except that the output is written
1788 -- to a file instead of to standard output. If the given fname
1789 -- does not start with a period, then it is the full name of the file
1790 -- to be written. If fname starts with a period, the name of the file
1791 -- is the concatenation of to the name of the file being compiled with
1792 -- fname where the period is replace by an underline. For example, if
1793 -- file xyz.adb is compiled with -gnatl=.lst, then the output is written
1794 -- to file xyz.adb_lst.
1798 -- /NOPOLLING (D)
1799 -- /POLLING
1800 --
1801 -- Enable polling. See the description of pragma Polling in the GNAT
1802 -- Reference Manual for full details.
1806 -- /PROJECT_FILE=filename
1807 --
1808 -- Specifies the main project file to be used. The project files rooted
1809 -- at the main project file will be parsed before the invocation of the
1810 -- compiler. The source and object directories to be searched will be
1811 -- communicated to the compiler through logical names
1812 -- ADA_PRJ_INCLUDE_FILE and ADA_PRJ_OBJECTS_FILE.
1816 -- /PRINT_STANDARD
1817 --
1818 -- cause the compiler to output a representation of package Standard
1819 -- in a form very close to standard Ada. It is not quite possible to
1820 -- do this and remain entirely Standard (since new numeric base types
1821 -- cannot be created in standard Ada), but the output is easily
1822 -- readable to any Ada programmer, and is useful to determine the
1823 -- characteristics of target dependent types in package Standard.
1836 -- /NOREPORT_ERRORS (D)
1837 -- /REPORT_ERRORS[=(keyword[,...])]
1838 --
1839 -- Change the way errors are reported. The following keywords are
1840 -- supported:
1841 --
1842 -- VERBOSE (D) Verbose mode. Full error output with source lines
1843 -- to SYS$OUTPUT.
1844 --
1845 -- BRIEF Generate the brief format error messages to
1846 -- SYS$OUTPUT as well as the verbose format message or
1847 -- full listing.
1848 --
1849 -- FULL Normally, the compiler suppresses error messages that
1850 -- are likely to be redundant. This keyword causes all
1851 -- error messages to be generated. One particular effect
1852 -- is for the case of references to undefined variables.
1853 -- If a given variable is referenced several times, the
1854 -- normal format of messages produces one error. With
1855 -- FULL, each undefined reference produces a separate
1856 -- error message.
1857 --
1858 -- IMMEDIATE Normally, the compiler saves up error messages and
1859 -- generates them at the end of compilation in proper
1860 -- sequence. This keyword causes error messages to be
1861 -- generated as soon as they are detected. The use of
1862 -- IMMEDIATE usually causes error messages to be
1863 -- generated out of sequence. Use it when the compiler
1864 -- blows up due to an internal error. In this case, the
1865 -- error messages may be lost. Sometimes blowups are
1866 -- the result of mishandled error messages, so you may
1867 -- want to run with this keyword to determine whether
1868 -- any error messages were generated.
1869 --
1870 -- DEFAULT Turn off VERBOSE and BRIEF. Same as /NOREPORT_ERRORS.
1874 -- NODOC (see /REPORT_ERRORS)
1893 -- /NOREPRESENTATION_INFO (D)
1894 -- /REPRESENTATION_INFO[=(keyword[,...])]
1895 --
1896 -- This qualifier controls output from the compiler of a listing showing
1897 -- representation information for declared types and objects.
1898 --
1899 -- ARRAYS (D) Size and alignment information is listed for
1900 -- declared array and record types.
1901 --
1902 -- ARRAYS_FILE Similar to ARRAYS, but the output is to a file
1903 -- with the name 'file_rep' where 'file' is the name
1904 -- of the corresponding source file.
1905 --
1906 -- NONE no information is output (equivalent to omitting
1907 -- the /REPRESENTATION_INFO qualifiers).
1908 --
1909 -- OBJECTS Size and alignment information is listed for all
1910 -- declared types and objects.
1911 --
1912 -- OBJECTS_FILE Similar to OBJECTS, but the output is to a file
1913 -- with the name 'file_rep' where 'file' is the name
1914 -- of the corresponding source file.
1915 --
1916 -- SYMBOLIC Symbolic expression information for values that
1917 -- are computed at run time for variant records.
1918 --
1919 -- SYMBOLIC_FILE Similar to SYMBOLIC, but the output is to a file
1920 -- with the name 'file_rep' where 'file' is the name
1921 -- of the corresponding source file.
1922 --
1923 -- DEFAULT Equivalent to ARRAYS.
1927 -- NODOC (see /REPRESENTATION_INFO)
1931 -- /RUNTIME_SYSTEM=xxx
1932 --
1933 -- Build against an alternate runtime system named xxx or RTS-xxx.
1937 -- /SEARCH=(directory[,...])
1938 --
1939 -- When looking for source files also look in directories specified.
2006 -- /NOSTYLE_CHECKS (D)
2007 -- /STYLE_CHECKS[=(keyword,[...])]
2008 --
2009 -- Normally, GNAT permits any code layout consistent with the reference
2010 -- manual requirements. This qualifier imposes style checking on the
2011 -- input source code. The following keywords are supported:
2012 --
2013 -- ALL_BUILTIN (D) Equivalent to the following list of options:
2014 -- 3, ATTRIBUTE, BLANKS, COMMENTS, END, VTABS,
2015 -- HTABS, IF_THEN, KEYWORD, LAYOUT, LINE_LENGTH,
2016 -- PRAGMA, REFERENCES, SPECS, TOKEN.
2017 --
2018 -- 1 .. 9 Specify indentation level from 1 to 9.
2019 -- The general style of required indentation is as
2020 -- specified by the examples in the Ada Reference
2021 -- Manual. Full line comments must be aligned with
2022 -- the -- starting on a column that is a multiple
2023 -- of the alignment level.
2024 --
2025 -- ATTRIBUTE Check attribute casing.
2026 -- Attribute names, including the case of keywords
2027 -- such as digits used as attributes names,
2028 -- must be written in mixed case, that is,
2029 -- the initial letter and any letter following an
2030 -- underscore must be uppercase.
2031 -- All other letters must be lowercase.
2032 --
2033 -- BLANKS Blanks not allowed at statement end.
2034 -- Trailing blanks are not allowed at the end of
2035 -- statements. The purpose of this rule, together
2036 -- with option HTABS (no horizontal tabs), is to
2037 -- enforce a canonical format for the use of
2038 -- blanks to separate source tokens.
2039 --
2040 -- COMMENTS Check comments.
2041 -- Comments must meet the following set of rules:
2042 --
2043 -- * The "--" that starts the column must either
2044 -- start in column one, or else at least one
2045 -- blank must precede this sequence.
2046 --
2047 -- * Comments that follow other tokens on a line
2048 -- must have at least one blank following the
2049 -- "--" at the start of the comment.
2050 --
2051 -- * Full line comments must have two blanks
2052 -- following the "--" that starts the comment,
2053 -- with the following exceptions.
2054 --
2055 -- * A line consisting only of the "--"
2056 -- characters, possibly preceded by blanks is
2057 -- permitted.
2058 --
2059 -- * A comment starting with "--x" where x is
2060 -- a special character is permitted. This
2061 -- allows proper processing of the output
2062 -- generated by specialized tools including
2063 -- gnatprep (where --! is used) and the SPARK
2064 -- annnotation language (where --# is used).
2065 -- For the purposes of this rule, a special
2066 -- character is defined as being in one of the
2067 -- ASCII ranges 16#21#..16#2F# or
2068 -- 16#3A#..16#3F#.
2069 --
2070 -- * A line consisting entirely of minus signs,
2071 -- possibly preceded by blanks, is permitted.
2072 -- This allows the construction of box
2073 -- comments where lines of minus signs are
2074 -- used to form the top and bottom of the box.
2075 --
2076 -- * If a comment starts and ends with "--" is
2077 -- permitted as long as at least one blank
2078 -- follows the initial "--". Together with
2079 -- the preceding rule, this allows the
2080 -- construction of box comments, as shown in
2081 -- the following example:
2082 --
2083 -- ---------------------------
2084 -- -- This is a box comment --
2085 -- ---------------------------
2086 --
2087 -- DOS_LINE_ENDINGS Check that no DOS line terminators are present
2088 -- All lines must be terminated by a single
2089 -- ASCII.LF character. In particular the DOS line
2090 -- terminator sequence CR / LF is not allowed).
2091 --
2092 -- END Check end/exit labels.
2093 -- Optional labels on end statements ending
2094 -- subprograms and on exit statements exiting
2095 -- named loops, are required to be present.
2096 --
2097 -- GNAT Enforces a set of style conventions that
2098 -- correspond to the style used in the GNAT
2099 -- source code. All compiler units are always
2100 -- compile with this keyword specified.
2101 --
2102 -- You can find the full documentation for the
2103 -- style conventions imposed by this keyword
2104 -- in the body of the package "Style" in the
2105 -- compiler sources.
2106 --
2107 -- You should not normally use this keyword.
2108 -- However, you MUST use it for compiling any
2109 -- language-defined unit, or for adding children
2110 -- to any language-defined unit other than
2111 -- "Standard".
2112 --
2113 -- HTABS No horizontal tabs.
2114 -- Horizontal tab characters are not permitted in
2115 -- the source text. Together with the BLANKS
2116 -- (no blanks at end of line) option, this
2117 -- enforces a canonical form for the use of blanks
2118 -- to separate source tokens.
2119 --
2120 -- IF_THEN Check if-then layout.
2121 -- The keyword then must appear either on the
2122 -- same line as the corresponding if, or on a line
2123 -- on its own, lined up under the if with at least
2124 -- one non-blank line in between containing all or
2125 -- part of the condition to be tested.
2126 --
2127 -- KEYWORD Check keyword casing.
2128 -- All keywords must be in lower case (with the
2129 -- exception of keywords such as digits used as
2130 -- attribute names to which this check does not
2131 -- apply).
2132 --
2133 -- LAYOUT Check layout.
2134 -- Layout of statement and declaration constructs
2135 -- must follow the recommendations in the Ada
2136 -- Reference Manual, as indicated by the form of
2137 -- the syntax rules. For example an else keyword
2138 -- must be lined up with the corresponding if
2139 -- keyword.
2140 --
2141 -- There are two respects in which the style rule
2142 -- enforced by this check option are more liberal
2143 -- than those in the Ada Reference Manual.
2144 -- First in the case of record declarations,
2145 -- it is permissible to put the record keyword on
2146 -- the same line as the type keyword, and then
2147 -- the end in end record must line up under type.
2148 -- For example, either of the following two
2149 -- layouts is acceptable:
2150 --
2151 -- type q is record
2152 -- a : integer;
2153 -- b : integer;
2154 -- end record;
2155 --
2156 -- type q is
2157 -- record
2158 -- a : integer;
2159 -- b : integer;
2160 -- end record;
2161 --
2162 -- Second, in the case of a block statement,
2163 -- a permitted alternative is to put the block
2164 -- label on the same line as the declare or begin
2165 -- keyword, and then line the end keyword up under
2166 -- the block label. For example both the following
2167 -- are permitted:
2168 --
2169 --
2170 --
2171 -- Block : declare
2172 -- A : Integer := 3;
2173 -- begin
2174 -- Proc (A, A);
2175 -- end Block;
2176 --
2177 -- Block :
2178 -- declare
2179 -- A : Integer := 3;
2180 -- begin
2181 -- Proc (A, A);
2182 -- end Block;
2183 --
2184 -- The same alternative format is allowed for
2185 -- loops. For example, both of the following are
2186 -- permitted:
2187 --
2188 --
2189 --
2190 -- Clear : while J < 10 loop
2191 -- A (J) := 0;
2192 -- end loop Clear;
2193 --
2194 -- Clear :
2195 -- while J < 10 loop
2196 -- A (J) := 0;
2197 -- end loop Clear;
2198 --
2199 --
2200 --
2201 -- LINE_LENGTH Check maximum line length.
2202 -- The length of source lines must not exceed 79
2203 -- characters, including any trailing blanks
2204 -- The value of 79 allows convenient display on
2205 -- an 80 character wide device or window, allowing
2206 -- for possible special treatment of 80 character
2207 -- lines.
2208 --
2209 -- NONE Clear any previously set style checks.
2210 --
2211 -- ORDERED_SUBPROGRAMS Check order of subprogram bodies.
2212 -- All subprogram bodies in a given scope (e.g.
2213 -- a package body) must be in alphabetical order.
2214 -- The ordering rule uses normal Ada rules for
2215 -- comparing strings, ignoring casing of letters,
2216 -- except that if there is a trailing numeric
2217 -- suffix, then the value of this suffix is used
2218 -- in the ordering (e.g. Junk2 comes before
2219 -- Junk10).
2220 --
2221 -- PRAGMA Check pragma casing.
2222 -- Pragma names must be written in mixed case,
2223 -- that is, the initial letter and any letter
2224 -- following an underscore must be uppercase.
2225 -- All other letters must be lowercase.
2226 --
2227 -- REFERENCES Check references.
2228 -- All identifier references must be cased in the
2229 -- same way as the corresponding declaration.
2230 -- No specific casing style is imposed on
2231 -- identifiers. The only requirement is for
2232 -- consistency of references with declarations.
2233 --
2234 -- SPECS Check separate specs.
2235 -- Separate declarations ("specs") are required
2236 -- for subprograms (a body is not allowed to serve
2237 -- as its own declaration). The only exception is
2238 -- that parameterless library level procedures are
2239 -- not required to have a separate declaration.
2240 -- This exception covers the most frequent form of
2241 -- main program procedures.
2242 --
2243 -- STANDARD_CASING Check casing of entities in Standard.
2244 -- Any identifier from Standard must be cased to
2245 -- match the presentation in the Ada Reference
2246 -- Manual (for example, Integer and ASCII.NUL).
2247 --
2248 -- TOKEN Check token spacing.
2249 -- The following token spacing rules are enforced:
2250 --
2251 -- * The keywords abs and not must be followed
2252 -- by a space.
2253 --
2254 -- * The token => must be surrounded by spaces.
2255 --
2256 -- * The token <> must be preceded by a space or
2257 -- a left parenthesis.
2258 --
2259 -- * Binary operators other than ** must be
2260 -- surrounded by spaces. There is no
2261 -- restriction on the layout of the ** binary
2262 -- operator.
2263 --
2264 -- * Colon must be surrounded by spaces.
2265 --
2266 -- * Colon-equal (assignment) must be surrounded
2267 -- by spaces.
2268 --
2269 -- * Comma must be the first non-blank character
2270 -- on the line, or be immediately preceded by
2271 -- a non-blank character, and must be followed
2272 -- by a space.
2273 --
2274 -- * If the token preceding a left paren ends
2275 -- with a letter or digit, then a space must
2276 -- separate the two tokens.
2277 --

2326 --
2327 -- Define or redefine a preprocessing symbol, associated with value.
2328 -- If "=value" is not specified, then the value of the symbol is True.
2329 -- A symbol is an identifier, following normal Ada (case-insensitive)
2330 -- rules for its syntax, and value is any sequence (including an empty
2331 -- sequence) of characters from the set (letters, digits, period,
2332 -- underline). Ada reserved words may be used as symbols, with the
2333 -- exceptions of "if", "else", "elsif", "end", "and", "or" and "then".

2335 -- A symbol declared with this qualifier on the command line replaces
2336 -- a symbol with the same name either in a definition file or specified

2344 -- /NOSYNTAX_ONLY (D)
2345 -- /SYNTAX_ONLY
2346 --
2347 -- Run GNAT in syntax checking only mode. You can check a series of
2348 -- files in a single command, and can use wild cards to specify such a
2349 -- group of files.
2350 --
2351 -- You may use other qualifiers in conjunction with this qualifier. In
2352 -- particular, /LIST and /REPORT_ERRORS=VERBOSE are useful to control the
2353 -- format of any generated error messages.
2354 --
2355 -- The output is simply the error messages, if any. No object file or ALI
2356 -- file is generated by a syntax-only compilation. Also, no units other
2357 -- than the one specified are accessed. For example, if a unit "X" with's
2358 -- a unit "Y", compiling unit "X" in syntax check only mode does not
2359 -- access the source file containing unit "Y".
2360 --
2361 -- Normally, GNAT allows only a single unit in a source file. However,
2362 -- this restriction does not apply in syntax-check-only mode, and it is

2397 --
2398 -- In normal operation mode the compiler first parses the program and
2399 -- determines if there are any syntax errors. If there are, appropriate
2400 -- error messages are generated and compilation is immediately
2401 -- terminated. This qualifier tells GNAT to continue with semantic

2403 -- detection of more errors in a single run. On the other hand, the

2484 --
2485 -- NONE No special checks for invalid values are

2492 --
2493 -- FULL Every assignment is checked for validity, so
2494 -- that it is impossible to assign invalid values.
2495 -- The RM specifically allows such assignments,
2496 -- but in this mode, invalid values can never be

2775 -- rather than errors. This is the default mode.
2776 -- It can be used to cancel the effect of an

2781 --
2782 -- OBSOLESCENT Activates warnings for calls to subprograms
2783 -- marked with pragma Obsolescent and for use of
2784 -- features in Annex J of the Ada Reference
2785 -- Manual. In the case of Annex J, not all

2856 -- NOUNREFERENCED_FORMALS Suppress warnings on unreferenced formals.
2857 -- Suppresses warnings for unreferenced formal
2858 -- parameters. Note that the combination UNUSED

2862 --
2863 -- UNUSED Activates warnings to be generated for entities
2864 -- that are defined but not referenced, and for
2865 -- units that are with'ed and not referenced. In
2866 -- the case of packages, a warning is also
2867 -- generated if no entities in the package are
2868 -- referenced. This means that if the package
2869 -- is referenced but the only references are in
2870 -- use clauses or renames declarations, a warning
2871 -- is still generated. A warning is also generated
2872 -- for a generic package that is with'ed but never
2873 -- instantiated. In the case where a package or

2917 -- /NOWIDE_CHARACTER_ENCODING (D)
2918 -- /WIDE_CHARACTER_ENCODING[=encode-type]
2919 --
2920 -- Specifies the mechanism used to encode wide characters. 'encode-type'
2921 -- is one of the following:
2922 --
2923 -- BRACKETS (D) A wide character is encoded as ["xxxx"] where XXXX
2924 -- are four hexadecimal digits representing the coding
2925 -- ('Pos value) of the character in type
2926 -- Wide_Character. The hexadecimal digits may use upper
2927 -- or lower case letters.
2928 --
2929 -- This notation can also be used for upper half
2930 -- Character values using the format ["xx"] where XX is
2931 -- two hexadecimal digits representing the coding ('Pos
2932 -- value) of the character in type Character (or
2933 -- Wide_Character). The hexadecimal digits may use upper
2934 -- of lower case.
2935 --
2936 -- NONE No wide characters are allowed. Same
2937 -- as /NOWIDE_CHARCTER_ENCODING.
2938 --
2939 -- HEX In this encoding, a wide character is represented by
2940 -- the following five character sequence: ESC a b c d
2941 -- Where 'a', 'b', 'c', and 'd' are the four hexadecimal
2942 -- characters (using uppercase letters) of the wide
2943 -- character code. For example, ESC A345 is used to
2944 -- represent the wide character with code 16#A345#. This
2945 -- scheme is compatible with use of the full
2946 -- Wide_Character set.
2947 --
2948 -- UPPER The wide character with encoding 16#abcd# where the
2949 -- upper bit is on (in other words, "a" is in the range
2950 -- 8-F) is represented as two bytes, 16#ab# and 16#cd#.
2951 -- The second byte may never be a format control
2952 -- character, but is not required to be in the upper
2953 -- half. This method can be also used for shift-JIS or
2954 -- EUC, where the internal coding matches the external
2955 -- coding.
2956 --
2957 -- SHIFT_JIS A wide character is represented by a two-character
2958 -- sequence, 16#ab# and 16#cd#, with the restrictions
2959 -- described for upper-half encoding as described above.
2960 -- The internal character code is the corresponding JIS
2961 -- character according to the standard algorithm for
2962 -- Shift-JIS conversion. Only characters defined in the
2963 -- JIS code set table can be used with this encoding
2964 -- method.
2965 --
2966 -- UTF8 A wide character is represented using
2967 -- UCS Transformation Format 8 (UTF-8) as defined in Annex
2968 -- R of ISO 10646-1/Am.2. Depending on the character
2969 -- value, the representation is a one, two, or three byte
2970 -- sequence:
2971 --
2972 -- 16#0000#-16#007f#: 2#0xxxxxxx#
2973 -- 16#0080#-16#07ff#: 2#110xxxxx# 2#10xxxxxx#
2974 -- 16#0800#-16#ffff#: 2#1110xxxx# 2#10xxxxxx# 2#10xxxxxx#
2975 --
2976 -- where the xxx bits correspond to the left-padded bits
2977 -- of the the 16-bit character value. Note that all lower
2978 -- half ASCII characters are represented as ASCII bytes
2979 -- and all upper half characters and other wide characters
2980 -- are represented as sequences of upper-half (The full
2981 -- UTF-8 scheme allows for encoding 31-bit characters as
2982 -- 6-byte sequences, but in this implementation, all UTF-8
2983 -- sequences of four or more bytes length will be treated
2984 -- as illegal).
2985 --
2986 -- EUC A wide character is represented by a two-character
2987 -- sequence 16#ab# and 16#cd#, with both characters being
2988 -- in the upper half. The internal character code is the
2989 -- corresponding JIS character according to the EUC
2990 -- encoding algorithm. Only characters defined in the JIS
2991 -- code set table can be used with this encoding method.

3000 -- /XDEBUG
3001 --
