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

251 --
252 -- Output complete list of elaboration-order dependencies, showing the
253 -- reason for each dependency. This output can be rather extensive but may
254 -- be useful in diagnosing problems with elaboration order. The output is
255 -- written to SYS$OUTPUT.

321 -- /MAIN (D)
322 --
323 -- The main program is in Ada.

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

397 -- /PESSIMISTIC_ELABORATION
398 --
399 -- Causes the binder to choose a "pessimistic" elaboration order, i.e. one
400 -- which is most likely to cause elaboration order problems. This can be
401 -- useful in testing portable code to make sure that there are no missing
402 -- elaborate pragmas.
406 -- /PROJECT_FILE=filename
407 --
408 -- Specifies the main project file to be used. The project files rooted
409 -- at the main project file will be parsed before the invocation of the
410 -- binder. The source and object directories to be searched will be
411 -- communicated to the binder through logical names ADA_PRJ_INCLUDE_FILE
412 -- and ADA_PRJ_OBJECTS_FILE.
421 -- /READ_SOURCES[=(keyword[,...])]
422 -- /NOREAD_SOURCES
423 --
424 -- The following keyword are accepted:
425 --
426 -- ALL (D) Require source files to be present. In this mode, the
427 -- binder insists on being able to locate all source files
428 -- that are referenced and checks their consistency. In
429 -- normal mode, if a source file cannot be located it is
430 -- simply ignored. If you specify the ALL keyword, a
431 -- missing source file is an error.
432 --
433 -- NONE Exclude source files. In this mode, the binder only
434 -- checks that ALI files are consistent with one another.
435 -- source files are not accessed. The binder runs faster
436 -- in this mode, and there is still a guarantee that the
437 -- resulting program is self-consistent.
438 --
439 -- If a source file has been edited since it was last
440 -- compiled and you specify the NONE keyword, the binder
441 -- will not detect that the object file is out of date
442 -- with the source file.
443 --
444 -- This is the same as specifying /NOREAD_SOURCES.
445 --
446 -- AVAILABLE Check that object files are consistent with one
447 -- another and are consistent with any source files that
448 -- can be located.
452 -- NODOC (see /READ_SOURCES)
456 -- /RENAME_MAIN=xxx
457 --
458 -- Renames the generated main program from main to xxx.
459 -- This is useful in the case of some cross-building environments, where
460 -- the actual main program is separate from the one generated
461 -- by GNAT BIND.
470 -- /REPORT_ERRORS[=(keyword[,...])]
471 -- VERBOSE (D)
472 -- BRIEF
473 -- DEFAULT
474 -- /NOREPORT_ERRORS
475 --
476 -- With the DEFAULT keyword (which is not the default when the binder is
477 -- run from GNAT BIND) or the /NOREPORT_ERRORS qualifier, brief error
478 -- messages are generated to SYS$ERROR. If the VERBOSE keyword is
479 -- present, a header is written to SYS$OUTPUT and any error messages are
480 -- directed to SYS$OUTPUT All that is written to SYS$ERROR is a brief
481 -- summary message.
482 --
483 -- If the BRIEF keyword is specified, the binder will generate brief error
484 -- messages to SYS$ERROR even if verbose mode is specified. This is
485 -- relevant only when used together with the VERBOSE keyword or /VERBOSE
486 -- qualifier.
490 -- NODOC (see /REPORT_ERRORS)
494 -- /NORESTRICTION_LIST (D)
495 -- /RESTRICTION_LIST
496 --
497 -- Generate list of pragma Rerstrictions that could be applied to the
498 -- current unit. This is useful for code audit purposes, and also may be
499 -- used to improve code generation in some cases.
503 -- /RUNTIME_SYSTEM=xxx
504 --
505 -- Binds against an alternate runtime system named xxx or RTS-xxx.
509 -- /SEARCH=(directory[,...])
510 --
511 -- When looking for source or object files also look in directories
512 -- specified.
513 --
514 -- This is the same as specifying both /LIBRARY_SEARCH and /SOURCE_SEARCH
515 -- for a directory.
519 -- /SHARED
520 -- /NOSHARED
521 --
522 -- Link against a shared GNAT run time when available.
526 -- /TIME_SLICE=nnn
527 --
528 -- Set the time slice value to nnn milliseconds. A value of zero means no
529 -- time slicing and also indicates to the tasking run time to match as
530 -- close as possible to the annex D requirements of the RM.
534 -- /SOURCE_SEARCH=(directory[,...])
535 --
536 -- When looking for source files also look in directories specified.
540 -- /STATIC
541 -- /NOSTATIC
542 --
543 -- Link against a static GNAT run time.
547 -- /STORE_TRACEBACKS (D)
548 -- /NOSTORE_TRACEBACKS
549 --
550 -- Store tracebacks in exception occurrences.
551 -- This is the default on VMS, with the zero-cost exception mechanism.
552 -- This qualifier has no impact, except when using the setjmp/longjmp
553 -- exception mechanism, with the GNAT COMPILE qualifier /LONGJMP_SETJMP.
557 -- /TIME_STAMP_CHECK (D)
558 --
559 -- Time stamp errors will be treated as errors.
560 --
561 -- /NOTIME_STAMP_CHECK
562 --
563 -- Ignore time stamp errors. Any time stamp error messages are treated as
564 -- warning messages. This switch essentially disconnects the normal
565 -- consistency checking, and the resulting program may have undefined
566 -- semantics if inconsistent units are present.
567 --
568 -- This means that /NOTIME_STAMP_CHECK should be used only in unusual
569 -- situations, with extreme care.
573 -- /VERBOSE (D)
574 -- /NOVERBOSE
575 --
576 -- Equivalent to /REPORT_ERRORS=VERBOSE.
585 -- /WARNINGS[=(keyword[,...])]
586 -- /NOWARNINGS
587 --
588 -- The following keywords are supported:
589 --
590 -- NORMAL (D) Print warning messages and treat them as warning.
591 -- SUPPRESS Suppress all warning messages (same as /NOWARNINGS).
592 -- ERROR Treat any warning messages as fatal errors
596 -- NODOC (see /WARNINGS)
600 -- /NOZERO_MAIN (D)
601 -- /ZERO_MAIN
602 --
603 -- Normally the binder checks that the unit name given on the command line
604 -- corresponds to a suitable main subprogram. When /ZERO_MAIN is used,
605 -- a list of ALI files can be given, and the execution of the program
606 -- consists of elaboration of these units in an appropriate order.

660 --
661 -- Compilation mode, handle configuration pragmas strictly according to
662 -- RM rules.
666 -- /FILE_NAME_MAX_LENGTH[=nnn]
667 --
668 -- Limit generated file names to NNN (default of 8) characters. This is

670 -- with systems like MS-DOS which limit the length of file names.
674 -- /NOHELP (D)
675 -- /HELP
676 --
677 -- Print usage information.
681 -- /NOOVERWRITE (D)
682 -- /OVERWRITE
683 --
684 -- Overwrite existing file names. Normally GNAT CHOP regards it as a
685 -- fatal error situation if there is already a file with the same name as
686 -- a file it would otherwise output. The /OVERWRITE qualifier bypasses
687 -- this check, and any such existing files will be silently overwritten.
691 -- /NOPRESERVE (D)
692 -- /PRESERVE
693 --
694 -- Causes the file modification time stamp of the input file to be
695 -- preserved and used for the time stamp of the output file(s). This may
696 -- be useful for preserving coherency of time stamps in an enviroment
697 -- where gnatchop is used as part of a standard build process.
701 -- /NOQUIET (D)
702 -- /QUIET
703 --
704 -- Work quietly, only output warnings and errors.
708 -- /NOREFERENCE (D)
709 -- /REFERENCE
710 --
711 -- Generate "Source_Reference" pragmas. Use this qualifier if the output
712 -- files are regarded as temporary and development is to be done in terms
713 -- of the original unchopped file. The /REFERENCE qualifier causes
714 -- "Source_Reference" pragmas to be inserted into each of the generated
715 -- files to refers back to the original file name and line number. The
716 -- result is that all error messages refer back to the original unchopped

718 --
719 -- In addition, the debugging information placed into the object file
720 -- (when the /DEBUG qualifier of GNAT COMPILE or GNAT MAKE is specified)

909 -- Switches for GNAT COMPILE --
910 -------------------------------
914 -- /NO83 (D)
915 -- /83
916 --
917 -- Although GNAT is primarily an Ada 95 compiler, it accepts this
918 -- qualifier to specify that an Ada 83 mode program is being compiled. If
919 -- you specify this qualifier, GNAT rejects Ada 95 extensions and applies
920 -- Ada 83 semantics. It is not possible to guarantee this qualifier does
921 -- a perfect job; for example, some subtle tests of pathological cases,
922 -- such as are found in ACVC tests that have been removed from the ACVC
923 -- suite for Ada 95, may not compile correctly. However for practical
924 -- purposes, using this qualifier should ensure that programs that
925 -- compile correctly under the /83 qualifier can be ported reasonably
926 -- easily to an Ada 83 compiler. This is the main use of this qualifier.
927 --
928 -- With few exceptions (most notably the need to use "<>" on
929 -- unconstrained generic formal parameters), it is not necessary to use
930 -- this qualifier switch when compiling Ada 83 programs, because, with
931 -- rare and obscure exceptions, Ada 95 is upwardly compatible with Ada
932 -- 83. This means that a correct Ada 83 program is usually also a correct
933 -- Ada 95 program.
937 -- /95 (D)
938 --
939 -- Allows GNAT to recognize the full range of Ada 95 constructs.
940 -- This is the normal default for GNAT Pro.
944 -- /05 (D)
945 --
946 -- Allows GNAT to recognize all implemented proposed Ada 2005
947 -- extensions. See features file for list of implemented features.
951 -- /NOASM (D)
952 -- /ASM
953 --
954 -- Use to cause the assembler source file to be generated, using S as the
955 -- filetype, instead of the object file. This may be useful if you need
956 -- to examine the generated assembly code.
973 -- /NOCHECKS
974 -- /CHECKS[=(keyword[,...])]
975 --
976 -- If you compile with the default options, GNAT will insert many runtime
977 -- checks into the compiled code, including code that performs range
978 -- checking against constraints, but not arithmetic overflow checking for
979 -- integer operations (including division by zero) or checks for access
980 -- before elaboration on subprogram calls. All other runtime checks, as
981 -- required by the Ada 95 Reference Manual, are generated by default.
982 --
983 -- You may specify one or more of the following keywords to the /CHECKS
984 -- qualifier to modify this behavior:
985 --
986 -- DEFAULT The behavior described above. This is the default
987 -- if the /CHECKS qualifier is not present on the
988 -- command line. Same as /NOCHECKS.
989 --
990 -- OVERFLOW Enables overflow checking for integer operations and
991 -- checks for access before elaboration on subprogram
992 -- calls. This causes GNAT to generate slower and larger
993 -- executable programs by adding code to check for both
994 -- overflow and division by zero (resulting in raising
995 -- "Constraint_Error" as required by Ada semantics).
996 -- Similarly, GNAT does not generate elaboration check
997 -- by default, and you must specify this keyword to
998 -- enable them.
999 --
1000 -- Note that this keyword does not affect the code
1001 -- generated for any floating-point operations; it
1002 -- applies only to integer operations. For floating-point,
1003 -- GNAT has the "Machine_Overflows" attribute set to
1004 -- "False" and the normal mode of operation is to generate
1005 -- IEEE NaN and infinite values on overflow or invalid
1006 -- operations (such as dividing 0.0 by 0.0).
1007 --
1008 -- ELABORATION Enables dynamic checks for access-before-elaboration
1009 -- on subprogram calls and generic instantiations.
1010 --
1011 -- ASSERTIONS The pragmas "Assert" and "Debug" normally have no
1012 -- effect and are ignored. This keyword causes "Assert"
1013 -- and "Debug" pragmas to be activated.
1014 --
1015 -- SUPPRESS_ALL Suppress all runtime checks as though you have "pragma
1016 -- Suppress (all_checks)" in your source. Use this switch
1017 -- to improve the performance of the code at the expense
1018 -- of safety in the presence of invalid data or program
1019 -- bugs.
1020 --
1021 -- DEFAULT Suppress the effect of any option OVERFLOW or
1022 -- ASSERTIONS.
1023 --
1024 -- FULL (D) Similar to OVERFLOW, but suppress the effect of any
1025 -- option ELABORATION or SUPPRESS_ALL.
1026 --
1027 -- These keywords only control the default setting of the checks. You
1028 -- may modify them using either "Suppress" (to remove checks) or
1029 -- "Unsuppress" (to add back suppressed checks) pragmas in your program
1030 -- source.
1034 -- NODOC (see /CHECKS)
1038 -- /NOCOMPRESS_NAMES (D)
1039 -- /COMPRESS_NAMES
1040 --
1041 -- Compress debug information and external symbol name table entries.
1042 -- In the generated debugging information, and also in the case of long
1043 -- external names, the compiler uses a compression mechanism if the name
1044 -- is very long. This compression method uses a checksum, and avoids
1045 -- trouble on some operating systems which have difficulty with very long
1046 -- names.
1050 -- /CONFIGURATION_PRAGMAS_FILE=file
1051 --
1052 -- Specify a configuration pragmas file that need to be taken into account
1056 -- /CURRENT_DIRECTORY (D)
1057 -- /NOCURRENT_DIRECTORY
1058 --
1059 -- Look for source files in the default directory.
1063 -- /DATA_PREPROCESSING=file_name
1064 --
1065 -- This qualifier indicates to the compiler the file name (without
1066 -- directory information) of the preprocessor data file to use.
1067 -- The preprocessor data file should be found in the source directories.
1068 --
1069 -- A preprocessing data file is a text file with significant lines
1070 -- indicating how should be preprocessed either a specific source or all
1071 -- sources not mentioned in other lines. A significant line is a non
1072 -- empty, non comment line. Comments are similar to Ada comments.
1073 --
1074 -- Each significant line starts with either a literal string or the
1075 -- character '*'. A literal string is the file name (without directory
1076 -- information) of the source to preprocess. A character '*' indicates the
1077 -- preprocessing for all the sources that are not specified explicitly on
1078 -- other lines. It is an error to have two lines with the same file name
1079 -- or two lines starting with the character '*'.
1080 --
1081 -- After the file name or the character '*', another optional literal
1082 -- string indicating the file name of the definition file to be used for
1083 -- preprocessing. (see 15.3 Form of Definitions File. The definition files
1084 -- are found by the compiler in one of the source directories. In some
1085 -- cases, when compiling a source in a directory other than the current
1086 -- directory, if the definition file is in the current directory, it may
1087 -- be necessary to add the current directory as a source directory through
1088 -- qualifier "/SEARCH=[]", otherwise the compiler would not find the
1089 -- definition file.
1090 --
1091 -- Then, optionally, switches similar to those of gnatprep may be found.
1092 -- Those switches are:
1093 --
1094 -- -b Causes both preprocessor lines and the lines deleted by
1095 -- preprocessing to be replaced by blank lines, preserving
1096 -- the line number. This switch is always implied;
1097 -- however, if specified after `-c' it cancels the effect
1098 -- of `-c'.
1099 --
1100 -- -c Causes both preprocessor lines and the lines deleted by
1101 -- preprocessing to be retained as comments marked with
1102 -- the special string "--! ".
1103 --
1104 -- -Dsymbol=value Define or redefine a symbol, associated with value.
1105 -- A symbol is an Ada identifier, or an Ada reserved word,
1106 -- with the exception of "if", "else", "elsif", "end",
1107 -- "and", "or" and "then". value is either a literal
1108 -- string, an Ada identifier or any Ada reserved word.
1109 -- A symbol declared with this switch replaces a symbol
1110 -- with the same name defined in a definition file.
1111 --
1112 -- -s Causes a sorted list of symbol names and values to be
1113 -- listed on the standard output file.
1114 --
1115 -- -u Causes undefined symbols to be treated as having the
1116 -- value FALSE in the context of a preprocessor test.
1117 -- In the absence of this option, an undefined symbol
1118 -- in a #if or #elsif test will be treated as an error.
1119 --
1120 -- Examples of valid lines in a preprocessor data file:
1121 --
1122 -- "toto.adb" "prep.def" -u
1123 -- -- preprocess "toto.adb", using definition file "prep.def",
1124 -- -- undefined symbol are False.
1125 --
1126 -- * -c -DVERSION=V101
1127 -- -- preprocess all other sources without a definition file;
1128 -- -- suppressed lined are commented; symbol VERSION has the value
1129 -- -- V101.
1130 --
1131 -- "titi.adb" "prep2.def" -s
1132 -- -- preprocess "titi.adb", using definition file "prep2.def";
1133 -- -- list all symbols with their values.
1148 -- /DEBUG[=debug-level]
1149 -- /NODEBUG
1150 --
1151 -- Specifies how much debugging information is to be included in
1152 -- the resulting object fie.
1153 --
1154 -- 'debug-level' is one of the following:
1155 --
1156 -- SYMBOLS (D) Include both debugger symbol records and traceback
1157 -- in the object file.
1158 --
1159 -- ALL Include debugger symbol records, traceback plus
1160 -- extra debug information in the object file.
1161 --
1162 -- NONE Excludes both debugger symbol records and traceback
1163 -- from the object file. Same as /NODEBUG.
1164 --
1165 -- TRACEBACK Includes only traceback records in the object
1166 -- file. This is the default when /DEBUG is not used.
1170 -- NODOC (see /Debug)
1177 -- /NODISTRIBUTION_STUBS (D)
1178 -- /DISTRIBUTION_STUBS[=dist-opt]
1179 --
1180 -- 'dist-opt' is either RECEIVER (the default) or SENDER and indicates
1181 -- that stubs for use in distributed programs (see the Distributed
1182 -- Systems Annex of the Ada RM) should be generated.
1186 -- NODOC (see /DISTRIBUTION_STUBS)
1190 -- /NOERROR_LIMIT (D)
1191 -- /ERROR_LIMIT=nnn
1192 --
1193 -- NNN is a decimal integer in the range of 1 to 999999 and limits the
1194 -- number of error messages to be generated to that number. Once that
1195 -- number has been reached, the compilation is abandoned.
1196 -- Specifying 999999 is equivalent to /NOERROR_LIMIT.
1200 -- NODOC (see /ERROR_LIMIT)
1204 -- /NOEXPAND_SOURCE (D)
1205 -- /EXPAND_SOURCE
1206 --
1207 -- Produces a listing of the expanded code in Ada source form. For
1208 -- example, all tasking constructs are reduced to appropriate run-time
1209 -- library calls.
1213 -- /NOEXTENSIONS_ALLOWED (D)
1214 -- /EXTENSIONS_ALLOWED
1215 --
1216 -- GNAT specific language extensions allowed.
1220 -- /EXTERNAL_REFERENCE="name=val"
1221 --
1222 -- Specifies an external reference to the project manager. Useful only if
1223 -- /PROJECT_FILE is used.
1224 --
1225 -- Example:
1226 -- /EXTERNAL_REFERENCE="DEBUG=TRUE"
1230 -- /FILE_NAME_MAX_LENGTH=nnn
1231 --
1232 -- Activates file name "krunching". NNN, a decimal integer in the range
1233 -- 1-999, indicates the maximum allowable length of a file name (not
1234 -- including the ADS or ADB filetype. The default is not to enable file
1235 -- name krunching.
1239 -- /NOFORCE_ALI (D)
1240 -- /FORCE_ALI
1241 --
1242 -- In normal operation mode, the .ALI file is not generated if any
1243 -- illegalities are detected in the program. The use of this qualifier
1244 -- forces generation of the .ALI file. This file is marked as being
1245 -- in error, so it cannot be used for binding purposes, but it does
1246 -- contain reasonably complete cross-reference information, and thus may
1247 -- be useful for use by tools (e.g. semantic browing tools or integrated
1248 -- development environments) that are driven from the .ALI file.
1252 -- /NOFULL_PATH_IN_BRIEF_MESSAGES (D)
1253 -- /FULL_PATH_IN_BRIEF_MESSAGES
1254 --
1255 -- When using project files, if some errors or warnings are detected
1256 -- during parsing and verbose mode is not in effect (no use of qualifier
1257 -- /VERBOSE), then error lines start with the full path name of the
1258 -- project file, rather than its simple file name.
1262 -- /NOHELP (D)
1263 -- /HELP
1264 --
1265 -- Output usage information.
1290 -- /NOIDENTIFIER_CHARACTER_SET (D)
1291 -- /IDENTIFIER_CHARACTER_SET=char-set
1292 --
1293 -- Normally GNAT recognizes the Latin-1 character set in source program
1294 -- identifiers, as described in the reference manual. This qualifier
1295 -- causes GNAT to recognize alternate character sets in identifiers.
1296 -- 'char-set' is one of the following strings indicating the character
1297 -- set:
1298 --
1299 -- DEFAULT (D) Equivalent to 1, below. Also equivalent to
1300 -- /NOIDENTIFIER_CHARACTER_SET.
1301 --
1302 -- 1 The basic character set is Latin-1. This character
1303 -- set is defined by ISO standard 8859, part 1. The lower
1304 -- half (character codes 16#00# ... 16#7F#) is identical
1305 -- to standard ASCII coding, but the upper half is used
1306 -- to represent additional characters. This includes
1307 -- extended letters used by European languages, such as
1308 -- the umlaut used in German.
1309 --
1310 -- You may use any of these extended characters freely
1311 -- in character or string literals. In addition, the
1312 -- extended characters that represent letters can be
1313 -- used in identifiers.
1314 --
1315 -- 2 Latin-2 letters allowed in identifiers, with uppercase
1316 -- and lowercase equivalence.
1317 --
1318 -- 3 Latin-3 letters allowed in identifiers, with uppercase
1319 -- and lower case equivalence.
1320 --
1321 -- 4 Latin-4 letters allowed in identifiers, with uppercase
1322 -- and lower case equivalence.
1323 --
1324 -- PC IBM PC code page 437. This code page is the normal
1325 -- default for PCs in the U.S. It corresponds to the
1326 -- original IBM PC character set. This set has some, but
1327 -- not all, of the extended Latin-1 letters, but these
1328 -- letters do not have the same encoding as Latin-1. In
1329 -- this mode, these letters are allowed in identifiers
1330 -- with uppercase and lowercase equivalence.
1331 --
1332 -- PC850 This code page (850) is a modification of 437 extended
1333 -- to include all the Latin-1 letters, but still not with
1334 -- the usual Latin-1 encoding. In this mode, all these
1335 -- letters are allowed in identifiers with uppercase and
1336 -- lower case equivalence.
1337 --
1338 -- FULL_UPPER Any character in the range 80-FF allowed in
1339 -- identifiers, and all are considered distinct. In
1340 -- other words, there are no uppercase and lower case
1341 -- equivalences in this range.
1342 --
1343 -- NO_UPPER No upper-half characters in the range 80-FF are
1344 -- allowed in identifiers. This gives Ada 95
1345 -- compatibility for identifier names.
1346 --
1347 -- WIDE GNAT allows wide character codes to appear in
1348 -- character and string literals, and also optionally
1349 -- in identifiers. See the /WIDE_CHARACTER_ENCODING
1350 -- qualifier for information on encoding formats.
1354 -- NODOC (see /IDENTIFIER_CHARACTER_SET)
1358 -- /NOIMMEDIATE_ERRORS (D)
1359 -- /IMMEDIATE_ERRORS
1360 --
1361 -- Causes errors to be displayed as soon as they are encountered, rather
1362 -- than after compilation is terminated. If GNAT terminates prematurely
1363 -- or goes into an infinite loop, the last error message displayed may
1364 -- help to pinpoint the culprit.
1373 -- /NOINLINE (D)
1374 -- /INLINE[=keyword]
1375 --
1376 -- Selects the level of inlining for your program. In the absence of this
1377 -- qualifier, GNAT does not attempt inlining across units and does not
1378 -- need to access the bodies of subprograms for which "pragma Inline" is
1379 -- specified if they are not in the current unit.
1380 --
1381 -- The supported keywords are as follows:
1382 --
1383 -- PRAGMA (D) Recognize and process "Inline" pragmas. However,
1384 -- for the inlining to actually occur, optimization
1385 -- must be enabled. This enables inlining across unit
1386 -- boundaries, that is, inlining a call in one unit of
1387 -- a subprogram declared in a with'ed unit. The compiler
1388 -- will access these bodies, creating an extra source
1389 -- dependency for the resulting object file, and where
1390 -- possible, the call will be inlined.
1391 --
1392 -- This qualifier also turns on full optimization and
1393 -- requests GNAT to try to attempt automatic inlining
1394 -- of small subprograms within a unit.
1395 --
1396 -- Specifying /OPTIMIZE=NONE will disable the main effect
1397 -- of this qualifier, but you may specify other
1398 -- optimization options, to get either lower
1399 -- (/OPTIMIZE=SOME) or higher (/OPTIMIZE=UNROLL_LOOPS)
1400 -- levels of optimization.
1401 --
1402 -- FULL Front end inlining. The front end inlining activated
1403 -- by this switch is generally more extensive, and quite
1404 -- often more effective than the standard PRAGMA inlining
1405 -- mode. It will also generate additional dependencies.
1406 --
1407 -- SUPPRESS Suppresses all inlining, even if other optimization
1408 -- or inlining switches are set.
1412 -- NODOC (see /INLINE)
1416 -- /NOLONGJMP_SETJMP (D)
1417 -- /LONGJMP_SETJMP
1418 --
1419 -- Causes the longjmp/setjmp approach to be used for exception handling.
1420 --
1421 -- The default mechanism for OpenVMS is zero cost exceptions. This
1422 -- qualifier can be used to modify this default, but it must be used for
1423 -- all units in the partition, including all run-time library units.
1424 -- One way to achieve this is to use the /ALL_FILES and /FORCE_COMPILE
1425 -- for gnatmake.
1426 -- This option is rarely used. One case in which it may be advantageous is
1427 -- in an application where exception raising is common and the overall
1428 -- performance of the application is improved by favoring exception
1429 -- propagation.
1433 -- /MAX_LINE_LENGTH=nnn
1434 --
1435 -- Set maximum line length.
1436 -- The length of lines must not exceed the given value nnn.
1440 -- /NOLIST (D)
1441 -- /LIST
1442 --
1443 -- Cause a full listing of the file to be generated.
1447 -- /MAPPING_FILE=file_name
1448 --
1449 -- Use mapping file file_name
1450 --
1451 -- A mapping file is a way to communicate to the compiler two mappings:
1452 -- from unit names to file names (without any directory information) and
1453 -- from file names to path names (with full directory information).
1454 -- These mappings are used by the compiler to short-circuit the path
1455 -- search.
1456 --
1457 -- The use of mapping files is not required for correct operation of the
1458 -- compiler, but mapping files can improve efficiency, particularly when
1459 -- sources are read over a slow network connection. In normal operation,
1460 -- you need not be concerned with the format or use of mapping files,
1461 -- and /MAPPING_FILE is not a qualifier that you would use explicitly.
1462 -- It is intended only for use by automatic tools such as GNAT MAKE
1463 -- running under the project file facility. The description here of the
1464 -- format of mapping files is provided for completeness and for possible
1465 -- use by other tools.
1466 --
1467 -- A mapping file is a sequence of sets of three lines. In each set, the
1468 -- first line is the unit name, in lower case, with "%s" appended for
1469 -- specifications and "%b" appended for bodies; the second line is the
1470 -- file name; and the third line is the path name.
1471 --
1472 -- Example:
1473 --
1474 -- main%b
1475 -- main.2_ada
1476 -- /gnat/project1/sources/main.2_ada
1477 --
1478 -- When qualifier ?MAPPING_FILE is specified, the compiler will create in
1479 -- memory the two mappings from the specified file. If there is any
1480 -- problem (non existent file, truncated file or duplicate entries),
1481 -- no mapping will be created.
1482 --
1483 -- Several /MAPPING_FILE qualifiers may be specified; however, only the
1484 -- last one on the command line will be taken into account.
1485 --
1486 -- When using a project file, GNAT MAKE creates a temporary mapping file
1487 -- and communicates it to the compiler using this switch.
1496 -- /MESSAGES_PROJECT_FILE[=messages-option]
1497 --
1498 -- Specifies the "verbosity" of the parsing of project files.
1499 -- messages-option may be one of the following:
1500 --
1501 -- DEFAULT (D) No messages are output if there is no error or warning.
1502 --
1503 -- MEDIUM A small number of messages are output.
1504 --
1505 -- HIGH A great number of messages are output, most of them not
1506 -- being useful for the user.
1510 -- /MAX_NESTING=nnn
1511 --
1512 -- Set maximum level of nesting of constructs (including subprograms,
1513 -- loops, blocks, packages, and conditionals).
1514 -- The level of nesting must not exceed the given value nnn.
1515 -- A value of zero disable this style check (not enabled by default).
1519 -- /NO_GNAT_ADC
1520 --
1521 -- Cause the compiler to ignore any configuration pragmas file GNAT.ADC
1522 -- in the default directory. Implied by qualifier /PROJECT_FILE.
1523 -- Often used in conjunction with qualifier /CONFIGURATION_PRAGMAS_FILE.
1527 -- /NOLOAD
1528 --
1529 -- Cause the compiler to operate in semantic check mode with full
1530 -- checking for all illegalities specified in the reference manual, but
1531 -- without generation of any source code (no object or ALI file
1532 -- generated).
1533 --
1534 -- Since dependent files must be accessed, you must follow the GNAT
1535 -- semantic restrictions on file structuring to operate in this mode:
1536 --
1537 -- o The needed source files must be accessible.
1538 -- o Each file must contain only one compilation unit.
1539 -- o The file name and unit name must match.
1540 --
1541 -- The output consists of error messages as appropriate. No object file
1542 -- or ALI file is generated. The checking corresponds exactly to the
1543 -- notion of legality in the Ada reference manual.

1592 -- INLINING Full optimization, and also attempt automatic inlining
1593 -- of small subprograms within a unit
1594 --
1595 -- UNROLL_LOOPS Try to unroll loops. This keyword may be specified

1597 -- unrolling usually, but not always, improves the
1598 -- performance of programs.
1599 --
1600 -- NO_STRICT_ALIASING
1601 -- Suppress aliasing analysis. When optimization is
1602 -- enabled (ALL or SOME above), the compiler assumes
1603 -- that pointers do in fact point to legitimate values
1604 -- of the pointer type (allocated from the proper pool).
1605 -- If this assumption is violated, e.g. by the use of
1606 -- unchecked conversion, then it may be necessary to

1631 -- ADA_PRJ_INCLUDE_FILE and ADA_PRJ_OBJECTS_FILE.
1635 -- /PRINT_STANDARD
1636 --
1637 -- cause the compiler to output a representation of package Standard

1662 -- to SYS$OUTPUT.
1663 --
1664 -- BRIEF Generate the brief format error messages to
1665 -- SYS$OUTPUT as well as the verbose format message or
1666 -- full listing.
1667 --
1668 -- FULL Normally, the compiler suppresses error messages that
1669 -- are likely to be redundant. This keyword causes all
1670 -- error messages to be generated. One particular effect
1671 -- is for the case of references to undefined variables.
1672 -- If a given variable is referenced several times, the
1673 -- normal format of messages produces one error. With
1674 -- FULL, each undefined reference produces a separate
1675 -- error message.
1676 --
1677 -- IMMEDIATE Normally, the compiler saves up error messages and
1678 -- generates them at the end of compilation in proper
1679 -- sequence. This keyword causes error messages to be
1680 -- generated as soon as they are detected. The use of
1681 -- IMMEDIATE usually causes error messages to be
1682 -- generated out of sequence. Use it when the compiler
1683 -- blows up due to an internal error. In this case, the
1684 -- error messages may be lost. Sometimes blowups are
1685 -- the result of mishandled error messages, so you may
1686 -- want to run with this keyword to determine whether
1687 -- any error messages were generated.
1688 --
1689 -- DEFAULT Turn off VERBOSE and BRIEF. Same as /NOREPORT_ERRORS.
1693 -- NODOC (see /REPORT_ERRORS)

1820 -- /STYLE_CHECKS[=(keyword,[...])]
1821 --
1822 -- Normally, GNAT permits any code layout consistent with the reference
1823 -- manual requirements. This qualifier imposes style checking on the
1824 -- input source code. The following keywords are supported:
1825 --
1826 -- ALL_BUILTIN (D) Equivalent to the following list of options:
1827 -- 3, ATTRIBUTE, BLANKS, COMMENTS, END, VTABS,
1828 -- HTABS, IF_THEN, KEYWORD, LAYOUT, LINE_LENGTH,
1829 -- PRAGMA, REFERENCES, SPECS, TOKEN.
1830 --
1831 -- 1 .. 9 Specify indentation level from 1 to 9.
1832 -- The general style of required indentation is as
1833 -- specified by the examples in the Ada Reference
1834 -- Manual. Full line comments must be aligned with
1835 -- the -- starting on a column that is a multiple
1836 -- of the alignment level.
1837 --
1838 -- ATTRIBUTE Check attribute casing.
1839 -- Attribute names, including the case of keywords
1840 -- such as digits used as attributes names,
1841 -- must be written in mixed case, that is,
1842 -- the initial letter and any letter following an
1843 -- underscore must be uppercase.
1844 -- All other letters must be lowercase.
1845 --
1846 -- BLANKS Blanks not allowed at statement end.
1847 -- Trailing blanks are not allowed at the end of
1848 -- statements. The purpose of this rule, together
1849 -- with option HTABS (no horizontal tabs), is to
1850 -- enforce a canonical format for the use of
1851 -- blanks to separate source tokens.
1852 --
1853 -- COMMENTS Check comments.
1854 -- Comments must meet the following set of rules:
1855 --
1856 -- * The "--" that starts the column must either
1857 -- start in column one, or else at least one
1858 -- blank must precede this sequence.
1859 --
1860 -- * Comments that follow other tokens on a line
1861 -- must have at least one blank following the
1862 -- "--" at the start of the comment.
1863 --
1864 -- * Full line comments must have two blanks
1865 -- following the "--" that starts the comment,
1866 -- with the following exceptions.
1867 --
1868 -- * A line consisting only of the "--"
1869 -- characters, possibly preceded by blanks is
1870 -- permitted.
1871 --
1872 -- * A comment starting with "--x" where x is
1873 -- a special character is permitted. This
1874 -- allows proper processing of the output
1875 -- generated by specialized tools including
1876 -- gnatprep (where --! is used) and the SPARK
1877 -- annnotation language (where --# is used).
1878 -- For the purposes of this rule, a special
1879 -- character is defined as being in one of the
1880 -- ASCII ranges 16#21#..16#2F# or
1881 -- 16#3A#..16#3F#.
1882 --
1883 -- * A line consisting entirely of minus signs,
1884 -- possibly preceded by blanks, is permitted.
1885 -- This allows the construction of box
1886 -- comments where lines of minus signs are
1887 -- used to form the top and bottom of the box.
1888 --
1889 -- * If a comment starts and ends with "--" is
1890 -- permitted as long as at least one blank
1891 -- follows the initial "--". Together with
1892 -- the preceding rule, this allows the
1893 -- construction of box comments, as shown in
1894 -- the following example:
1895 --
1896 -- ---------------------------
1897 -- -- This is a box comment --
1898 -- ---------------------------
1899 --
1900 -- END Check end/exit labels.
1901 -- Optional labels on end statements ending
1902 -- subprograms and on exit statements exiting
1903 -- named loops, are required to be present.
1904 --
1905 -- GNAT Enforces a set of style conventions that
1906 -- correspond to the style used in the GNAT
1907 -- source code. All compiler units are always
1908 -- compile with this keyword specified.
1909 --
1910 -- You can find the full documentation for the
1911 -- style conventions imposed by this keyword
1912 -- in the body of the package "Style" in the
1913 -- compiler sources.
1914 --
1915 -- You should not normally use this keyword.
1916 -- However, you MUST use it for compiling any
1917 -- language-defined unit, or for adding children
1918 -- to any language-defined unit other than
1919 -- "Standard".
1920 --
1921 -- HTABS No horizontal tabs.
1922 -- Horizontal tab characters are not permitted in
1923 -- the source text. Together with the BLANKS
1924 -- (no blanks at end of line) option, this
1925 -- enforces a canonical form for the use of blanks
1926 -- to separate source tokens.
1927 --
1928 -- IF_THEN Check if-then layout.
1929 -- The keyword then must appear either on the
1930 -- same line as the corresponding if, or on a line
1931 -- on its own, lined up under the if with at least
1932 -- one non-blank line in between containing all or
1933 -- part of the condition to be tested.
1934 --
1935 -- KEYWORD Check keyword casing.
1936 -- All keywords must be in lower case (with the
1937 -- exception of keywords such as digits used as
1938 -- attribute names to which this check does not
1939 -- apply).
1940 --
1941 -- LAYOUT Check layout.
1942 -- Layout of statement and declaration constructs
1943 -- must follow the recommendations in the Ada
1944 -- Reference Manual, as indicated by the form of
1945 -- the syntax rules. For example an else keyword
1946 -- must be lined up with the corresponding if
1947 -- keyword.
1948 --
1949 -- There are two respects in which the style rule
1950 -- enforced by this check option are more liberal
1951 -- than those in the Ada Reference Manual.
1952 -- First in the case of record declarations,
1953 -- it is permissible to put the record keyword on
1954 -- the same line as the type keyword, and then
1955 -- the end in end record must line up under type.
1956 -- For example, either of the following two
1957 -- layouts is acceptable:
1958 --
1959 -- type q is record
1960 -- a : integer;
1961 -- b : integer;
1962 -- end record;
1963 --
1964 -- type q is
1965 -- record
1966 -- a : integer;
1967 -- b : integer;
1968 -- end record;
1969 --
1970 -- Second, in the case of a block statement,
1971 -- a permitted alternative is to put the block
1972 -- label on the same line as the declare or begin
1973 -- keyword, and then line the end keyword up under
1974 -- the block label. For example both the following
1975 -- are permitted:
1976 --
1977 --
1978 --
1979 -- Block : declare
1980 -- A : Integer := 3;
1981 -- begin
1982 -- Proc (A, A);
1983 -- end Block;
1984 --
1985 -- Block :
1986 -- declare
1987 -- A : Integer := 3;
1988 -- begin
1989 -- Proc (A, A);
1990 -- end Block;
1991 --
1992 -- The same alternative format is allowed for
1993 -- loops. For example, both of the following are
1994 -- permitted:
1995 --
1996 --
1997 --
1998 -- Clear : while J < 10 loop
1999 -- A (J) := 0;
2000 -- end loop Clear;
2001 --
2002 -- Clear :
2003 -- while J < 10 loop
2004 -- A (J) := 0;
2005 -- end loop Clear;
2006 --
2007 --
2008 --
2009 -- LINE_LENGTH Check maximum line length.
2010 -- The length of source lines must not exceed 79
2011 -- characters, including any trailing blanks
2012 -- The value of 79 allows convenient display on
2013 -- an 80 character wide device or window, allowing
2014 -- for possible special treatment of 80 character
2015 -- lines.
2016 --
2017 -- NONE Clear any previously set style checks.
2018 --
2019 -- ORDERED_SUBPROGRAMS Check order of subprogram bodies.
2020 -- All subprogram bodies in a given scope (e.g.
2021 -- a package body) must be in alphabetical order.
2022 -- The ordering rule uses normal Ada rules for
2023 -- comparing strings, ignoring casing of letters,
2024 -- except that if there is a trailing numeric
2025 -- suffix, then the value of this suffix is used
2026 -- in the ordering (e.g. Junk2 comes before
2027 -- Junk10).
2028 --
2029 -- NONE The default behavior. Same as /NOSTYLE_CHECKS.
2030 --
2031 -- PRAGMA Check pragma casing.
2032 -- Pragma names must be written in mixed case,
2033 -- that is, the initial letter and any letter
2034 -- following an underscore must be uppercase.
2035 -- All other letters must be lowercase.
2036 --
2037 -- REFERENCES Check references.
2038 -- All identifier references must be cased in the
2039 -- same way as the corresponding declaration.
2040 -- No specific casing style is imposed on
2041 -- identifiers. The only requirement is for
2042 -- consistency of references with declarations.
2043 --
2044 -- RM_COLUMN_LAYOUT Enforce the layout conventions suggested by
2045 -- the examples and syntax rules of the Ada
2046 -- Language Reference Manual. For example, an
2047 -- "else" must line up with an "if" and code in
2048 -- the "then" and "else" parts must be indented.
2049 -- The compiler considers violations of the
2050 -- layout rules a syntax error if you specify
2051 -- this keyword.
2052 --
2053 -- SPECS Check separate specs.
2054 -- Separate declarations ("specs") are required
2055 -- for subprograms (a body is not allowed to serve
2056 -- as its own declaration). The only exception is
2057 -- that parameterless library level procedures are
2058 -- not required to have a separate declaration.
2059 -- This exception covers the most frequent form of
2060 -- main program procedures.
2061 --
2062 -- STANDARD_CASING Check casing of entities in Standard.
2063 -- Any identifier from Standard must be cased to
2064 -- match the presentation in the Ada Reference
2065 -- Manual (for example, Integer and ASCII.NUL).
2066 --
2067 -- TOKEN Check token spacing.
2068 -- The following token spacing rules are enforced:
2069 --
2070 -- * The keywords abs and not must be followed
2071 -- by a space.
2072 --
2073 -- * The token => must be surrounded by spaces.
2074 --
2075 -- * The token <> must be preceded by a space or
2076 -- a left parenthesis.
2077 --
2078 -- * Binary operators other than ** must be
2079 -- surrounded by spaces. There is no
2080 -- restriction on the layout of the ** binary
2081 -- operator.
2082 --
2083 -- * Colon must be surrounded by spaces.
2084 --
2085 -- * Colon-equal (assignment) must be surrounded
2086 -- by spaces.
2087 --
2088 -- * Comma must be the first non-blank character
2089 -- on the line, or be immediately preceded by
2090 -- a non-blank character, and must be followed
2091 -- by a space.
2092 --
2093 -- * If the token preceding a left paren ends
2094 -- with a letter or digit, then a space must
2095 -- separate the two tokens.
2096 --
2097 -- * A right parenthesis must either be the
2098 -- first non-blank character on a line, or it
2099 -- must be preceded by a non-blank character.
2100 --
2101 -- * A semicolon must not be preceded by
2102 -- a space, and must not be followed by
2103 -- a non-blank character.
2104 --
2105 -- * A unary plus or minus may not be followed
2106 -- by a space.
2107 --
2108 -- * A vertical bar must be surrounded by
2109 -- spaces.
2110 --
2111 -- In the above rules, appearing in column one is
2112 -- always permitted, that is, counts as meeting
2113 -- either a requirement for a required preceding
2114 -- space, or as meeting a requirement for no
2115 -- preceding space.
2116 --
2117 -- Appearing at the end of a line is also always
2118 -- permitted, that is, counts as meeting either
2119 -- a requirement for a following space,
2120 -- or as meeting a requirement for no following
2121 -- space.
2122 --
2123 -- VTABS No form feeds or vertical tabs.
2124 -- Form feeds or vertical tab characters are not
2125 -- permitted in the source text.
2129 -- NODOC (see /STYLE_CHECKS)
2133 -- /SYMBOL_PREPROCESSING="symbol=value"
2134 --
2135 -- Define or redefine a preprocessing symbol, associated with value.
2136 -- If "=value" is not specified, then the value of the symbol is True.
2137 -- A symbol is an identifier, following normal Ada (case-insensitive)
2138 -- rules for its syntax, and value is any sequence (including an empty
2139 -- sequence) of characters from the set (letters, digits, period,
2140 -- underline). Ada reserved words may be used as symbols, with the
2141 -- exceptions of "if", "else", "elsif", "end", "and", "or" and "then".
2142 --
2143 -- A symbol declared with this qualifier on the command line replaces
2144 -- a symbol with the same name either in a definition file or specified
2145 -- with a switch -D in the preprocessor data file.
2146 --
2147 -- This qualifier is similar to qualifier /ASSOCIATE of
2148 -- GNAT PREPROCESSING.
2152 -- /NOSYNTAX_ONLY (D)
2153 -- /SYNTAX_ONLY
2154 --
2155 -- Run GNAT in syntax checking only mode. You can check a series of
2156 -- files in a single command, and can use wild cards to specify such a
2157 -- group of files.
2158 --
2159 -- You may use other qualifiers in conjunction with this qualifier. In
2160 -- particular, /LIST and /REPORT_ERRORS=VERBOSE are useful to control the
2161 -- format of any generated error messages.
2162 --
2163 -- The output is simply the error messages, if any. No object file or ALI
2164 -- file is generated by a syntax-only compilation. Also, no units other
2165 -- than the one specified are accessed. For example, if a unit "X" with's
2166 -- a unit "Y", compiling unit "X" in syntax check only mode does not
2167 -- access the source file containing unit "Y".
2168 --
2169 -- Normally, GNAT allows only a single unit in a source file. However,
2170 -- this restriction does not apply in syntax-check-only mode, and it is
2171 -- possible to check a file containing multiple compilation units
2172 -- concatenated together. This is primarily used by the GNAT CHOP
2173 -- command.
2177 -- /TABLE_MULTIPLIER=nnn
2178 --
2179 -- All compiler tables start at nnn times usual starting size.
2183 -- /TRACE_UNITS
2184 -- /NOTRACE_UNITS
2185 --
2186 -- This switch that does for the frontend what /VERBOSE does for the
2187 -- backend. The system prints the name of each unit, either a compilation
2188 -- unit or nested unit, as it is being analyzed.
2192 -- /TREE_OUTPUT
2193 -- /NOTREE_OUTPUT
2194 --
2195 -- Cause GNAT to write the internal tree for a unit to a file (with the
2196 -- filetype ATB for a body or ATS for a spec). This is not normally
2197 -- required, but is used by separate analysis tools. Typically these
2198 -- tools do the necessary compilations automatically, so you should never
2199 -- have to specify this switch in normal operation.
2203 -- /TRY_SEMANTICS
2204 -- /NOTRY_SEMANTICS
2205 --
2206 -- In normal operation mode the compiler first parses the program and
2207 -- determines if there are any syntax errors. If there are, appropriate
2208 -- error messages are generated and compilation is immediately
2209 -- terminated. This qualifier tells GNAT to continue with semantic
2210 -- analysis even if syntax errors have been found. This may enable the
2211 -- detection of more errors in a single run. On the other hand, the
2212 -- semantic analyzer is more likely to encounter some internal fatal
2213 -- error when given a syntactically invalid tree.
2217 -- /NOUNITS_LIST (D)
2218 -- /UNITS_LIST
2219 --
2220 -- Print a list of units required by this compilation on SYS$OUTPUT. The

2307 -- This behavior is allowed (but not required) by

2428 --
2429 -- In addition to error messages, corresponding to illegalities as
2430 -- defined in the reference manual, the compiler detects two kinds of
2431 -- warning situations. First, the compiler considers some constructs
2432 -- suspicious and generates a warning message to alert you to a possible
2433 -- error. Second, if the compiler detects a situation that is sure to
2434 -- raise an exception at runtime, it generates a warning message.
2435 --
2436 -- You may specify the following keywords to change this behavior:
2437 --
2438 -- DEFAULT (D) The default behavior above.
2439 --
2440 -- ALL Activate all optional warnings.
2441 -- Activates most optional warning messages,
2442 -- see remaining list in this section for
2443 -- details on optional warning messages that
2444 -- can be individually controlled.
2445 -- The warnings that are not turned on by
2446 -- this option are BIASED_ROUNDING,
2447 -- IMPLICIT_DEREFERENCE, HIDING and
2448 -- ELABORATION. All other optional Ada
2449 -- warnings are turned on.
2450 --
2451 -- NOALL Suppress all optional errors.
2452 -- Suppresses all optional warning messages
2453 -- that can be activated by option ALL.
2454 --
2455 -- ALL_GCC Request additional messages from the GCC
2456 -- backend. Most of these are not relevant
2457 -- to Ada.
2458 --
2459 -- CONDITIONALS Activate warnings for conditional
2460 -- Expressions used in tests that are known
2461 -- to be True or False at compile time. The
2462 -- default is that such warnings are not
2463 -- generated.
2464 --
2465 -- NOCONDITIONALS Suppress warnings for conditional
2466 -- expressions used in tests that are known
2467 -- to be True or False at compile time.
2468 --
2469 -- IMPLICIT_DEREFERENCE Activate warnings on implicit dereferencing.
2470 -- The use of a prefix of an access type in an
2471 -- indexed component, slice, or selected component
2472 -- without an explicit .all will generate
2473 -- a warning. With this warning enabled, access
2474 -- checks occur only at points where an explicit
2475 -- .all appears in the source code (assuming no
2476 -- warnings are generated as a result of this
2477 -- option). The default is that such warnings are
2478 -- not generated. Note that /WARNINGS=ALL does not
2479 -- affect the setting of this warning option.
2480 --
2481 -- NOIMPLICIT_DEREFERENCE Suppress warnings on implicit dereferencing.
2482 -- in indexed components, slices, and selected
2483 -- components.
2484 --
2485 -- ELABORATION Activate warnings on missing pragma
2486 -- Elaborate_All statements. The default is
2487 -- that such warnings are not generated.
2488 --
2489 -- NOELABORATION Suppress warnings on missing pragma
2490 -- Elaborate_All statements.
2491 --
2492 -- ERRORS Warning messages are to be treated as errors.
2493 -- The warning string still appears, but the
2494 -- warning messages are counted as errors, and
2495 -- prevent the generation of an object file.
2496 --
2497 -- HIDING Activate warnings on hiding declarations.
2498 -- A declaration is considered hiding if it is
2499 -- for a non-overloadable entity, and it declares
2500 -- an entity with the same name as some other
2501 -- entity that is directly or use-visible. The
2502 -- default is that such warnings are not
2503 -- generated.
2504 --
2505 -- NOHIDING Suppress warnings on hiding declarations.
2506 --
2507 -- IMPLEMENTATION Activate warnings for a with of an internal
2508 -- GNAT implementation unit, defined as any unit
2509 -- from the Ada, Interfaces, GNAT, DEC or
2510 -- System hierarchies that is not documented in
2511 -- either the Ada Reference Manual or the GNAT
2512 -- Programmer's Reference Manual. Such units are
2513 -- intended only for internal implementation
2514 -- purposes and should not be with'ed by user
2515 -- programs. The default is that such warnings
2516 -- are generated.
2517 --
2518 -- NOIMPLEMENTATION Disables warnings for a with of an internal
2519 -- GNAT implementation unit.
2520 --
2521 -- INEFFECTIVE_INLINE Activate warnings on ineffective pragma Inlines
2522 -- Activates warnings for failure of front end
2523 -- inlining (activated by /INLINE=FULL) to inline
2524 -- a particular call. There are many reasons for
2525 -- not being able to inline a call, including most
2526 -- commonly that the call is too complex to
2527 -- inline. This warning can also be turned on
2528 -- using /INLINE=FULL.
2529 --
2530 -- NOINEFFECTIVE_INLINE Suppress warnings on ineffective pragma Inlines
2531 -- Suppresses warnings on ineffective pragma
2532 -- Inlines. If the inlining mechanism cannot
2533 -- inline a call, it will simply ignore the
2534 -- request silently.
2535 --
2536 -- MODIFIED_UNREF Activates warnings for variables that are
2537 -- assigned (using an initialization value or with
2538 -- one or more assignment statements) but whose
2539 -- value is never read. The warning is suppressed
2540 -- for volatile variables and also for variables
2541 -- that are renamings of other variables or for
2542 -- which an address clause is given. This warning
2543 -- can also be turned on using /WARNINGS/OPTIONAL.
2544 --
2545 -- NOMODIFIED_UNREF Disables warnings for variables that are
2546 -- assigned or initialized, but never read.
2547 --
2548 -- NORMAL Sets normal warning mode, in which enabled
2549 -- warnings are issued and treated as warnings
2550 -- rather than errors. This is the default mode.
2551 -- It can be used to cancel the effect of an
2552 -- explicit /WARNINGS=SUPPRESS or
2553 -- /WARNINGS=ERRORS. It also cancels the effect
2554 -- of the implicit /WARNINGS=ERRORS that is
2555 -- activated by the use of /STYLE=GNAT.
2556 --
2557 -- OBSOLESCENT Activates warnings for calls to subprograms
2558 -- marked with pragma Obsolescent and for use of
2559 -- features in Annex J of the Ada Reference
2560 -- Manual. In the case of Annex J, not all
2561 -- features are flagged. In particular use of the
2562 -- renamed packages (like Text_IO), use of package
2563 -- ASCII and use of the attribute 'Constrained are
2564 -- not flagged, since these are very common and
2565 -- would generate many annoying positive warnings.
2566 -- The default is that such warnings are not
2567 -- generated.
2568 --
2569 -- NOOBSOLESCENT Disables warnings on use of obsolescent
2570 -- features.
2571 --
2572 -- OPTIONAL Activate all optional warning messages.
2573 -- See other options under this qualifier
2574 -- for details on optional warning messages
2575 -- that can be individually controlled. The
2576 -- one exception is that /WARNINGS=OPTIONAL
2577 -- doesn't activate warnings for hiding
2578 -- variables (/WARNINGS=HIDING), so if this
2579 -- warning is required it must be explicitly
2580 -- set.
2581 --
2582 -- NOOPTIONAL Suppress all optional warning messages.
2583 -- See other options under this qualifier
2584 -- for details on optional warning messages
2585 -- that can be individually controlled.
2586 --
2587 -- OVERLAYS Activate warnings for possibly unintended
2588 -- initialization effects of defining address
2589 -- clauses that cause one variable to overlap
2590 -- another. The default is that such warnings
2591 -- are generated.
2592 --
2593 -- NOOVERLAYS Suppress warnings on possibly unintended
2594 -- initialization effects of defining address
2595 -- clauses that cause one variable to overlap
2596 -- another.
2597 --
2598 -- REDUNDANT Activate warnings for redundant constructs.
2599 -- In particular assignments of a variable to
2600 -- itself, and a type conversion that converts
2601 -- an object to its own type. The default
2602 -- is that such warnings are not generated.
2603 --
2604 -- NOREDUNDANT Suppress warnings for redundant constructs.
2605 --
2606 -- SUPPRESS Completely suppresse the output of all warning
2607 -- messages. Same as /NOWARNINGS.
2608 --
2609 -- UNCHECKED_CONVERSIONS Activates warnings on unchecked conversions.
2610 -- Causes warnings to be generated for
2611 -- unchecked conversions when the two types are
2612 -- known at compile time to have different sizes.
2613 -- The default is that such warnings are
2614 -- generated.
2615 --
2616 -- NOUNCHECKED_CONVERSIONS Suppress warnings for unchecked conversions.
2617 --
2618 -- UNINITIALIZED Generate warnings for uninitialized variables.
2619 -- This is a GCC option, not an Ada option.
2620 -- You must also specify the /OPTIMIZE qualifier
2621 -- with a value other than NONE (in other words,
2622 -- this keyword works only if optimization is
2623 -- turned on).
2624 --
2625 -- UNREFERENCED_FORMALS Activate warnings on unreferenced formals.
2626 -- Causes a warning to be generated if a formal
2627 -- parameter is not referenced in the body of
2628 -- the subprogram. This warning can also be turned
2629 -- on using option ALL or UNUSED.
2630 --
2631 -- NOUNREFERENCED_FORMALS Suppress warnings on unreferenced formals.
2632 -- Suppresses warnings for unreferenced formal
2633 -- parameters. Note that the combination UNUSED
2634 -- followed by NOUNREFERENCED_FORMALS has the
2635 -- effect of warning on unreferenced entities
2636 -- other than subprogram formals.
2637 --
2638 -- UNUSED Activates warnings to be generated for entities
2639 -- that are defined but not referenced, and for
2640 -- units that are with'ed and not referenced. In
2641 -- the case of packages, a warning is also
2642 -- generated if no entities in the package are
2643 -- referenced. This means that if the package
2644 -- is referenced but the only references are in
2645 -- use clauses or renames declarations, a warning
2646 -- is still generated. A warning is also generated
2647 -- for a generic package that is with'ed but never
2648 -- instantiated. In the case where a package or
2649 -- subprogram body is compiled, and there is a
2650 -- with on the corresponding spec that is only
2651 -- referenced in the body, a warning is also
2652 -- generated, noting that the with can be moved
2653 -- to the body. The default is that such warnings
2654 -- are not generated.
2655 --
2656 -- NOUNUSED Suppress warnings for unused entities and
2657 -- packages.
2658 --
2659 -- VARIABLES_UNINITIALIZED Activates warnings on unassigned variables.
2660 -- Causes warnings to be generated when a variable
2661 -- is accessed which may not be properly
2662 -- uninitialized.
2663 -- The default is that such warnings are
2664 -- generated.
2665 --
2666 -- NOVARIABLES_UNINITIALIZED Suppress warnings for uninitialized
2667 -- variables.
2671 -- NODOC (see /WARNINGS)
2675 -- /NO_BACK_END_WARNINGS
2676 --
2677 -- Inhibit all warning messages of the GCC back-end.
2694 -- /NOWIDE_CHARACTER_ENCODING (D)
2695 -- /WIDE_CHARACTER_ENCODING[=encode-type]
2696 --
2697 -- Specifies the mechanism used to encode wide characters. 'encode-type'
2698 -- is one of the following:
2699 --
2700 -- BRACKETS (D) A wide character is encoded as ["xxxx"] where XXXX
2701 -- are four hexadecimal digits representing the coding
2702 -- ('Pos value) of the character in type
2703 -- Wide_Character. The hexadecimal digits may use upper
2704 -- or lower case letters.
2705 --
2706 -- This notation can also be used for upper half
2707 -- Character values using the format ["xx"] where XX is
2708 -- two hexadecimal digits representing the coding ('Pos
2709 -- value) of the character in type Character (or
2710 -- Wide_Character). The hexadecimal digits may use upper
2711 -- of lower case.
2712 --
2713 -- NONE No wide characters are allowed. Same
2714 -- as /NOWIDE_CHARCTER_ENCODING.
2715 --
2716 -- HEX In this encoding, a wide character is represented by
2717 -- the following five character sequence: ESC a b c d
2718 -- Where 'a', 'b', 'c', and 'd' are the four hexadecimal
2719 -- characters (using uppercase letters) of the wide
2720 -- character code. For example, ESC A345 is used to
2721 -- represent the wide character with code 16#A345#. This
2722 -- scheme is compatible with use of the full
2723 -- Wide_Character set.
2724 --
2725 -- UPPER The wide character with encoding 16#abcd# where the
2726 -- upper bit is on (in other words, "a" is in the range
2727 -- 8-F) is represented as two bytes, 16#ab# and 16#cd#.
2728 -- The second byte may never be a format control
2729 -- character, but is not required to be in the upper
2730 -- half. This method can be also used for shift-JIS or
2731 -- EUC, where the internal coding matches the external
2732 -- coding.
2733 --
2734 -- SHIFT_JIS A wide character is represented by a two-character
2735 -- sequence, 16#ab# and 16#cd#, with the restrictions
2736 -- described for upper-half encoding as described above.
2737 -- The internal character code is the corresponding JIS
2738 -- character according to the standard algorithm for
2739 -- Shift-JIS conversion. Only characters defined in the
2740 -- JIS code set table can be used with this encoding
2741 -- method.
2742 --
2743 -- UTF8 A wide character is represented using
2744 -- UCS Transformation Format 8 (UTF-8) as defined in Annex
2745 -- R of ISO 10646-1/Am.2. Depending on the character
2746 -- value, the representation is a one, two, or three byte
2747 -- sequence:
2748 --
2749 -- 16#0000#-16#007f#: 2#0xxxxxxx#
2750 -- 16#0080#-16#07ff#: 2#110xxxxx# 2#10xxxxxx#
2751 -- 16#0800#-16#ffff#: 2#1110xxxx# 2#10xxxxxx# 2#10xxxxxx#
2752 --
2753 -- where the xxx bits correspond to the left-padded bits
2754 -- of the the 16-bit character value. Note that all lower
2755 -- half ASCII characters are represented as ASCII bytes
2756 -- and all upper half characters and other wide characters
2757 -- are represented as sequences of upper-half (The full
2758 -- UTF-8 scheme allows for encoding 31-bit characters as
2759 -- 6-byte sequences, but in this implementation, all UTF-8
2760 -- sequences of four or more bytes length will be treated
2761 -- as illegal).
2762 --
2763 -- EUC A wide character is represented by a two-character
2764 -- sequence 16#ab# and 16#cd#, with both characters being
2765 -- in the upper half. The internal character code is the
2766 -- corresponding JIS character according to the EUC
2767 -- encoding algorithm. Only characters defined in the JIS
2768 -- code set table can be used with this encoding method.
2772 -- NODOC (see /WIDE_CHARACTER_ENCODING)
2776 -- /NOXDEBUG (D)
2777 -- /XDEBUG
2778 --
2779 -- Output expanded source files for source level debugging.
2780 -- The expanded source (see /EXPAND_SOURCE) is written to files
2781 -- with names formed by appending "_DG" to the input file name,
2782 -- The debugging information generated by the /DEBUG qualifier will then
2783 -- refer to the generated file. This allows source level debugging using
2784 -- the generated code which is sometimes useful for complex code, for
2785 -- example to find out exactly which part of a complex construction
2786 -- raised an exception.
2793 -- /XREF[=keyword]
2794 --
2795 -- Normally the compiler generates full cross-referencing information in
2796 -- the .ALI file. This information is used by a number of tools,
2797 -- including GNAT FIND and GNAT XREF.
2798 --
2799 -- GENERATE (D) Generate cross-referencing information.
2800 --
2801 -- SUPPRESS Suppress cross-referencing information.
2802 -- This saves some space and may slightly
2803 -- speed up compilation, but means that some
2804 -- tools cannot be used.
2808 -- /ZERO_COST_EXCEPTIONS
2809 -- /NOZERO_COST_EXCEPTIONS
2810 --
2811 -- As zero-cost exceptions is the default on VMS, this qualifier has

2904 -- /BIND_FILE=file_name
2905 --
2906 -- Specifies file_name as the bind file to process. If this qualifier is

2983 -- If this switch is present, FIND and XREF will parse the read-only
2984 -- files found in the library search path. Otherwise, these files will
2985 -- be ignored. This option can be used to protect Gnat sources or your

4568 --
4569 -- The difference between "GNAT style comment line indentation" and
