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

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

315 --
316 -- Output linker options to SYS$OUTPUT. Includes library search
317 -- paths, contents of pragmas Ident and Linker_Options, and
318 -- libraries added by GNAT BIND.
322 -- /MAIN (D)
323 --
324 -- The main program is in Ada.
325 --
326 -- /NOMAIN

378 --
379 -- Output chosen elaboration order. The output is written to SYS$OUTPUT.
383 -- /OUTPUT=filename
384 --
385 -- File name to use for the program containing the elaboration code.
389 -- /NOOUTPUT
390 --
391 -- Check only. Do not generate the binder output file.
392 --
393 -- In this mode the binder performs all error checks but does not generate
394 -- an output file.
398 -- /PESSIMISTIC_ELABORATION
399 --
400 -- Causes the binder to choose a "pessimistic" elaboration order, i.e. one
401 -- which is most likely to cause elaboration order problems. This can be
402 -- useful in testing portable code to make sure that there are no missing
403 -- elaborate pragmas.
407 -- /PROJECT_FILE=filename
408 --
409 -- Specifies the main project file to be used. The project files rooted
410 -- at the main project file will be parsed before the invocation of the
411 -- binder. The source and object directories to be searched will be
412 -- communicated to the binder through logical names ADA_PRJ_INCLUDE_FILE
413 -- and ADA_PRJ_OBJECTS_FILE.
422 -- /READ_SOURCES[=(keyword[,...])]
423 -- /NOREAD_SOURCES
424 --
425 -- The following keyword are accepted:
426 --
427 -- ALL (D) Require source files to be present. In this mode, the
428 -- binder insists on being able to locate all source files
429 -- that are referenced and checks their consistency. In
430 -- normal mode, if a source file cannot be located it is
431 -- simply ignored. If you specify the ALL keyword, a
432 -- missing source file is an error.
433 --
434 -- NONE Exclude source files. In this mode, the binder only
435 -- checks that ALI files are consistent with one another.
436 -- source files are not accessed. The binder runs faster
437 -- in this mode, and there is still a guarantee that the
438 -- resulting program is self-consistent.
439 --
440 -- If a source file has been edited since it was last
441 -- compiled and you specify the NONE keyword, the binder
442 -- will not detect that the object file is out of date
443 -- with the source file.
444 --
445 -- This is the same as specifying /NOREAD_SOURCES.
446 --
447 -- AVAILABLE Check that object files are consistent with one
448 -- another and are consistent with any source files that
449 -- can be located.
453 -- NODOC (see /READ_SOURCES)
457 -- /RENAME_MAIN=xxx
458 --
459 -- Renames the generated main program from main to xxx.
460 -- This is useful in the case of some cross-building environments, where
461 -- the actual main program is separate from the one generated
462 -- by GNAT BIND.
471 -- /REPORT_ERRORS[=(keyword[,...])]
472 -- VERBOSE (D)
473 -- BRIEF
474 -- DEFAULT
475 -- /NOREPORT_ERRORS
476 --
477 -- With the DEFAULT keyword (which is not the default when the binder is
478 -- run from GNAT BIND) or the /NOREPORT_ERRORS qualifier, brief error
479 -- messages are generated to SYS$ERROR. If the VERBOSE keyword is
480 -- present, a header is written to SYS$OUTPUT and any error messages are
481 -- directed to SYS$OUTPUT All that is written to SYS$ERROR is a brief
482 -- summary message.
483 --
484 -- If the BRIEF keyword is specified, the binder will generate brief error
485 -- messages to SYS$ERROR even if verbose mode is specified. This is
486 -- relevant only when used together with the VERBOSE keyword or /VERBOSE
487 -- qualifier.
491 -- NODOC (see /REPORT_ERRORS)
496 -- /NORESTRICTION_LIST (D)
497 -- /RESTRICTION_LIST
498 --
499 -- Generate list of pragma Rerstrictions that could be applied to the
500 -- current unit. This is useful for code audit purposes, and also may be
501 -- used to improve code generation in some cases.
505 -- /RUNTIME_SYSTEM=xxx
506 --
507 -- Binds against an alternate runtime system named xxx or RTS-xxx.
511 -- /SEARCH=(directory[,...])
512 --
513 -- When looking for source or object files also look in directories
514 -- specified.
515 --
516 -- This is the same as specifying both /LIBRARY_SEARCH and /SOURCE_SEARCH
517 -- for a directory.
521 -- /SHARED (D)
522 -- /NOSHARED
523 --
524 -- Link against a shared GNAT run time when available.
528 -- /TIME_SLICE=nnn
529 --
530 -- Set the time slice value to nnn milliseconds. A value of zero means no
531 -- time slicing and also indicates to the tasking run time to match as
532 -- close as possible to the annex D requirements of the RM.
536 -- /SOURCE_SEARCH=(directory[,...])
537 --
538 -- When looking for source files also look in directories specified.
542 -- /STORE_TRACEBACKS (D)
543 -- /NOSTORE_TRACEBACKS
544 --
545 -- Store tracebacks in exception occurrences.
546 -- This is the default on VMS, with the zero-cost exception mechanism.
547 -- This qualifier has no impact, except when using the setjmp/longjmp
548 -- exception mechanism, with the GNAT COMPILE qualifier /LONGJMP_SETJMP.
552 -- /TIME_STAMP_CHECK (D)
553 --
554 -- Time stamp errors will be treated as errors.
555 --
556 -- /NOTIME_STAMP_CHECK
557 --
558 -- Ignore time stamp errors. Any time stamp error messages are treated as
559 -- warning messages. This switch essentially disconnects the normal
560 -- consistency checking, and the resulting program may have undefined
561 -- semantics if inconsistent units are present.
562 --
563 -- This means that /NOTIME_STAMP_CHECK should be used only in unusual
564 -- situations, with extreme care.
568 -- /VERBOSE (D)
569 -- /NOVERBOSE
570 --
571 -- Equivalent to /REPORT_ERRORS=VERBOSE.
580 -- /WARNINGS[=(keyword[,...])]
581 -- /NOWARNINGS
582 --
583 -- The following keywords are supported:
584 --
585 -- NORMAL (D) Print warning messages and treat them as warning.
586 -- SUPPRESS Suppress all warning messages (same as /NOWARNINGS).
587 -- ERROR Treat any warning messages as fatal errors
591 -- NODOC (see /WARNINGS)
595 -- /NOZERO_MAIN (D)
596 -- /ZERO_MAIN
597 --
598 -- Normally the binder checks that the unit name given on the command line
599 -- corresponds to a suitable main subprogram. When /ZERO_MAIN is used,
600 -- a list of ALI files can be given, and the execution of the program
601 -- consists of elaboration of these units in an appropriate order.

896 -- Switches for GNAT COMPILE --
897 -------------------------------
901 -- /NO83 (D)
902 -- /83
903 --
904 -- Although GNAT is primarily an Ada 95 compiler, it accepts this
905 -- qualifier to specify that an Ada 83 mode program is being compiled. If
906 -- you specify this qualifier, GNAT rejects Ada 95 extensions and applies
907 -- Ada 83 semantics. It is not possible to guarantee this qualifier does
908 -- a perfect job; for example, some subtle tests of pathological cases,
909 -- such as are found in ACVC tests that have been removed from the ACVC
910 -- suite for Ada 95, may not compile correctly. However for practical
911 -- purposes, using this qualifier should ensure that programs that
912 -- compile correctly under the /83 qualifier can be ported reasonably
913 -- easily to an Ada 83 compiler. This is the main use of this qualifier.
914 --
915 -- With few exceptions (most notably the need to use "<>" on
916 -- unconstrained generic formal parameters), it is not necessary to use
917 -- this qualifier switch when compiling Ada 83 programs, because, with
918 -- rare and obscure exceptions, Ada 95 is upwardly compatible with Ada
919 -- 83. This means that a correct Ada 83 program is usually also a correct
920 -- Ada 95 program.
924 -- /95 (D)
925 --
926 -- Same as /NO83.
927 --
928 -- /NO95
929 --
930 -- Same as /83.
934 -- /NOASM (D)
935 -- /ASM
936 --
937 -- Use to cause the assembler source file to be generated, using S as the
938 -- filetype, instead of the object file. This may be useful if you need
939 -- to examine the generated assembly code.
956 -- /NOCHECKS
957 -- /CHECKS[=(keyword[,...])]
958 --
959 -- If you compile with the default options, GNAT will insert many runtime
960 -- checks into the compiled code, including code that performs range
961 -- checking against constraints, but not arithmetic overflow checking for
962 -- integer operations (including division by zero) or checks for access
963 -- before elaboration on subprogram calls. All other runtime checks, as
964 -- required by the Ada 95 Reference Manual, are generated by default.
965 --
966 -- You may specify one or more of the following keywords to the /CHECKS
967 -- qualifier to modify this behavior:
968 --
969 -- DEFAULT The behavior described above. This is the default
970 -- if the /CHECKS qualifier is not present on the
971 -- command line. Same as /NOCHECKS.
972 --
973 -- OVERFLOW Enables overflow checking for integer operations and
974 -- checks for access before elaboration on subprogram
975 -- calls. This causes GNAT to generate slower and larger
976 -- executable programs by adding code to check for both
977 -- overflow and division by zero (resulting in raising
978 -- "Constraint_Error" as required by Ada semantics).
979 -- Similarly, GNAT does not generate elaboration check
980 -- by default, and you must specify this keyword to
981 -- enable them.
982 --
983 -- Note that this keyword does not affect the code
984 -- generated for any floating-point operations; it
985 -- applies only to integer operations. For floating-point,
986 -- GNAT has the "Machine_Overflows" attribute set to
987 -- "False" and the normal mode of operation is to generate
988 -- IEEE NaN and infinite values on overflow or invalid
989 -- operations (such as dividing 0.0 by 0.0).
990 --
991 -- ELABORATION Enables dynamic checks for access-before-elaboration
992 -- on subprogram calls and generic instantiations.
993 --
994 -- ASSERTIONS The pragmas "Assert" and "Debug" normally have no
995 -- effect and are ignored. This keyword causes "Assert"
996 -- and "Debug" pragmas to be activated.
997 --
998 -- SUPPRESS_ALL Suppress all runtime checks as though you have "pragma
999 -- Suppress (all_checks)" in your source. Use this switch
1000 -- to improve the performance of the code at the expense
1001 -- of safety in the presence of invalid data or program
1002 -- bugs.
1003 --
1004 -- DEFAULT Suppress the effect of any option OVERFLOW or
1005 -- ASSERTIONS.
1006 --
1007 -- FULL (D) Similar to OVERFLOW, but suppress the effect of any
1008 -- option ELABORATION or SUPPRESS_ALL.
1009 --
1010 -- These keywords only control the default setting of the checks. You
1011 -- may modify them using either "Suppress" (to remove checks) or
1012 -- "Unsuppress" (to add back suppressed checks) pragmas in your program
1013 -- source.
1017 -- NODOC (see /CHECKS)
1021 -- /NOCOMPRESS_NAMES (D)
1022 -- /COMPRESS_NAMES
1023 --
1024 -- Compress debug information and external symbol name table entries.
1025 -- In the generated debugging information, and also in the case of long
1026 -- external names, the compiler uses a compression mechanism if the name
1027 -- is very long. This compression method uses a checksum, and avoids
1028 -- trouble on some operating systems which have difficulty with very long
1029 -- names.
1033 -- /CONFIGURATION_PRAGMAS_FILE=file
1034 --
1035 -- Specify a configuration pragmas file that need to be taken into account
1039 -- /CURRENT_DIRECTORY (D)
1040 -- /NOCURRENT_DIRECTORY
1041 --
1042 -- Look for source files in the default directory.
1046 -- /DATA_PREPROCESSING=file_name
1047 --
1048 -- This qualifier indicates to the compiler the file name (without
1049 -- directory information) of the preprocessor data file to use.
1050 -- The preprocessor data file should be found in the source directories.
1051 --
1052 -- A preprocessing data file is a text file with significant lines
1053 -- indicating how should be preprocessed either a specific source or all
1054 -- sources not mentioned in other lines. A significant line is a non
1055 -- empty, non comment line. Comments are similar to Ada comments.
1056 --
1057 -- Each significant line starts with either a literal string or the
1058 -- character '*'. A literal string is the file name (without directory
1059 -- information) of the source to preprocess. A character '*' indicates the
1060 -- preprocessing for all the sources that are not specified explicitly on
1061 -- other lines. It is an error to have two lines with the same file name
1062 -- or two lines starting with the character '*'.
1063 --
1064 -- After the file name or the character '*', another optional literal
1065 -- string indicating the file name of the definition file to be used for
1066 -- preprocessing. (see 15.3 Form of Definitions File. The definition files
1067 -- are found by the compiler in one of the source directories. In some
1068 -- cases, when compiling a source in a directory other than the current
1069 -- directory, if the definition file is in the current directory, it may
1070 -- be necessary to add the current directory as a source directory through
1071 -- qualifier "/SEARCH=[]", otherwise the compiler would not find the
1072 -- definition file.
1073 --
1074 -- Then, optionally, switches similar to those of gnatprep may be found.
1075 -- Those switches are:
1076 --
1077 -- -b Causes both preprocessor lines and the lines deleted by
1078 -- preprocessing to be replaced by blank lines, preserving
1079 -- the line number. This switch is always implied;
1080 -- however, if specified after `-c' it cancels the effect
1081 -- of `-c'.
1082 --
1083 -- -c Causes both preprocessor lines and the lines deleted by
1084 -- preprocessing to be retained as comments marked with
1085 -- the special string "--! ".
1086 --
1087 -- -Dsymbol=value Define or redefine a symbol, associated with value.
1088 -- A symbol is an Ada identifier, or an Ada reserved word,
1089 -- with the exception of "if", "else", "elsif", "end",
1090 -- "and", "or" and "then". value is either a literal
1091 -- string, an Ada identifier or any Ada reserved word.
1092 -- A symbol declared with this switch replaces a symbol
1093 -- with the same name defined in a definition file.
1094 --
1095 -- -s Causes a sorted list of symbol names and values to be
1096 -- listed on the standard output file.
1097 --
1098 -- -u Causes undefined symbols to be treated as having the
1099 -- value FALSE in the context of a preprocessor test.
1100 -- In the absence of this option, an undefined symbol
1101 -- in a #if or #elsif test will be treated as an error.
1102 --
1103 -- Examples of valid lines in a preprocessor data file:
1104 --
1105 -- "toto.adb" "prep.def" -u
1106 -- -- preprocess "toto.adb", using definition file "prep.def",
1107 -- -- undefined symbol are False.
1108 --
1109 -- * -c -DVERSION=V101
1110 -- -- preprocess all other sources without a definition file;
1111 -- -- suppressed lined are commented; symbol VERSION has the value
1112 -- -- V101.
1113 --
1114 -- "titi.adb" "prep2.def" -s
1115 -- -- preprocess "titi.adb", using definition file "prep2.def";
1116 -- -- list all symbols with their values.
1131 -- /DEBUG[=debug-level]
1132 -- /NODEBUG
1133 --
1134 -- Specifies how much debugging information is to be included in
1135 -- the resulting object fie.
1136 --
1137 -- 'debug-level' is one of the following:
1138 --
1139 -- SYMBOLS (D) Include both debugger symbol records and traceback
1140 -- in the object file.
1141 --
1142 -- ALL Include debugger symbol records, traceback plus
1143 -- extra debug information in the object file.
1144 --
1145 -- NONE Excludes both debugger symbol records and traceback
1146 -- from the object file. Same as /NODEBUG.
1147 --
1148 -- TRACEBACK Includes only traceback records in the object
1149 -- file. This is the default when /DEBUG is not used.
1153 -- NODOC (see /Debug)
1160 -- /NODISTRIBUTION_STUBS (D)
1161 -- /DISTRIBUTION_STUBS[=dist-opt]
1162 --
1163 -- 'dist-opt' is either RECEIVER (the default) or SENDER and indicates
1164 -- that stubs for use in distributed programs (see the Distributed
1165 -- Systems Annex of the Ada RM) should be generated.
1169 -- NODOC (see /DISTRIBUTION_STUBS)
1173 -- /NOERROR_LIMIT (D)
1174 -- /ERROR_LIMIT=nnn
1175 --
1176 -- NNN is a decimal integer in the range of 1 to 999999 and limits the
1177 -- number of error messages to be generated to that number. Once that
1178 -- number has been reached, the compilation is abandoned.
1179 -- Specifying 999999 is equivalent to /NOERROR_LIMIT.
1183 -- NODOC (see /ERROR_LIMIT)
1187 -- /NOEXPAND_SOURCE (D)
1188 -- /EXPAND_SOURCE
1189 --
1190 -- Produces a listing of the expanded code in Ada source form. For
1191 -- example, all tasking constructs are reduced to appropriate run-time
1192 -- library calls.
1196 -- /NOEXTENSIONS_ALLOWED (D)
1197 -- /EXTENSIONS_ALLOWED
1198 --
1199 -- GNAT specific language extensions allowed.
1203 -- /EXTERNAL_REFERENCE="name=val"
1204 --
1205 -- Specifies an external reference to the project manager. Useful only if
1206 -- /PROJECT_FILE is used.
1207 --
1208 -- Example:
1209 -- /EXTERNAL_REFERENCE="DEBUG=TRUE"
1213 -- /FILE_NAME_MAX_LENGTH=nnn
1214 --
1215 -- Activates file name "krunching". NNN, a decimal integer in the range
1216 -- 1-999, indicates the maximum allowable length of a file name (not
1217 -- including the ADS or ADB filetype. The default is not to enable file
1218 -- name krunching.
1222 -- /NOFORCE_ALI (D)
1223 -- /FORCE_ALI
1224 --
1225 -- In normal operation mode, the .ALI file is not generated if any
1226 -- illegalities are detected in the program. The use of this qualifier
1227 -- forces generation of the .ALI file. This file is marked as being
1228 -- in error, so it cannot be used for binding purposes, but it does
1229 -- contain reasonably complete cross-reference information, and thus may
1230 -- be useful for use by tools (e.g. semantic browing tools or integrated
1231 -- development environments) that are driven from the .ALI file.
1235 -- /NOFULL_PATH_IN_BRIEF_MESSAGES (D)
1236 -- /FULL_PATH_IN_BRIEF_MESSAGES
1237 --
1238 -- When using project files, if some errors or warnings are detected
1239 -- during parsing and verbose mode is not in effect (no use of qualifier
1240 -- /VERBOSE), then error lines start with the full path name of the
1241 -- project file, rather than its simple file name.
1245 -- /NOHELP (D)
1246 -- /HELP
1247 --
1248 -- Output usage information.
1273 -- /NOIDENTIFIER_CHARACTER_SET (D)
1274 -- /IDENTIFIER_CHARACTER_SET=char-set
1275 --
1276 -- Normally GNAT recognizes the Latin-1 character set in source program
1277 -- identifiers, as described in the reference manual. This qualifier
1278 -- causes GNAT to recognize alternate character sets in identifiers.
1279 -- 'char-set' is one of the following strings indicating the character
1280 -- set:
1281 --
1282 -- DEFAULT (D) Equivalent to 1, below. Also equivalent to
1283 -- /NOIDENTIFIER_CHARACTER_SET.
1284 --
1285 -- 1 The basic character set is Latin-1. This character
1286 -- set is defined by ISO standard 8859, part 1. The lower
1287 -- half (character codes 16#00# ... 16#7F#) is identical
1288 -- to standard ASCII coding, but the upper half is used
1289 -- to represent additional characters. This includes
1290 -- extended letters used by European languages, such as
1291 -- the umlaut used in German.
1292 --
1293 -- You may use any of these extended characters freely
1294 -- in character or string literals. In addition, the
1295 -- extended characters that represent letters can be
1296 -- used in identifiers.
1297 --
1298 -- 2 Latin-2 letters allowed in identifiers, with uppercase
1299 -- and lowercase equivalence.
1300 --
1301 -- 3 Latin-3 letters allowed in identifiers, with uppercase
1302 -- and lower case equivalence.
1303 --
1304 -- 4 Latin-4 letters allowed in identifiers, with uppercase
1305 -- and lower case equivalence.
1306 --
1307 -- PC IBM PC code page 437. This code page is the normal
1308 -- default for PCs in the U.S. It corresponds to the
1309 -- original IBM PC character set. This set has some, but
1310 -- not all, of the extended Latin-1 letters, but these
1311 -- letters do not have the same encoding as Latin-1. In
1312 -- this mode, these letters are allowed in identifiers
1313 -- with uppercase and lowercase equivalence.
1314 --
1315 -- PC850 This code page (850) is a modification of 437 extended
1316 -- to include all the Latin-1 letters, but still not with
1317 -- the usual Latin-1 encoding. In this mode, all these
1318 -- letters are allowed in identifiers with uppercase and
1319 -- lower case equivalence.
1320 --
1321 -- FULL_UPPER Any character in the range 80-FF allowed in
1322 -- identifiers, and all are considered distinct. In
1323 -- other words, there are no uppercase and lower case
1324 -- equivalences in this range.
1325 --
1326 -- NO_UPPER No upper-half characters in the range 80-FF are
1327 -- allowed in identifiers. This gives Ada 95
1328 -- compatibility for identifier names.
1329 --
1330 -- WIDE GNAT allows wide character codes to appear in
1331 -- character and string literals, and also optionally
1332 -- in identifiers. See the /WIDE_CHARACTER_ENCODING
1333 -- qualifier for information on encoding formats.
1337 -- NODOC (see /IDENTIFIER_CHARACTER_SET)
1341 -- /NOIMMEDIATE_ERRORS (D)
1342 -- /IMMEDIATE_ERRORS
1343 --
1344 -- Causes errors to be displayed as soon as they are encountered, rather
1345 -- than after compilation is terminated. If GNAT terminates prematurely
1346 -- or goes into an infinite loop, the last error message displayed may
1347 -- help to pinpoint the culprit.
1356 -- /NOINLINE (D)
1357 -- /INLINE[=keyword]
1358 --
1359 -- Selects the level of inlining for your program. In the absence of this
1360 -- qualifier, GNAT does not attempt inlining across units and does not
1361 -- need to access the bodies of subprograms for which "pragma Inline" is
1362 -- specified if they are not in the current unit.
1363 --
1364 -- The supported keywords are as follows:
1365 --
1366 -- PRAGMA (D) Recognize and process "Inline" pragmas. However,
1367 -- for the inlining to actually occur, optimization
1368 -- must be enabled. This enables inlining across unit
1369 -- boundaries, that is, inlining a call in one unit of
1370 -- a subprogram declared in a with'ed unit. The compiler
1371 -- will access these bodies, creating an extra source
1372 -- dependency for the resulting object file, and where
1373 -- possible, the call will be inlined.
1374 --
1375 -- This qualifier also turns on full optimization and
1376 -- requests GNAT to try to attempt automatic inlining
1377 -- of small subprograms within a unit.
1378 --
1379 -- Specifying /OPTIMIZE=NONE will disable the main effect
1380 -- of this qualifier, but you may specify other
1381 -- optimization options, to get either lower
1382 -- (/OPTIMIZE=SOME) or higher (/OPTIMIZE=UNROLL_LOOPS)
1383 -- levels of optimization.
1384 --
1385 -- FULL Front end inlining. The front end inlining activated
1386 -- by this switch is generally more extensive, and quite
1387 -- often more effective than the standard PRAGMA inlining
1388 -- mode. It will also generate additional dependencies.
1389 --
1390 -- SUPPRESS Suppresses all inlining, even if other optimization
1391 -- or inlining switches are set.
1395 -- NODOC (see /INLINE)
1399 -- /NOLONGJMP_SETJMP (D)
1400 -- /LONGJMP_SETJMP
1401 --
1402 -- Causes the longjmp/setjmp approach to be used for exception handling.
1403 --
1404 -- The default mechanism for OpenVMS is zero cost exceptions. This
1405 -- qualifier can be used to modify this default, but it must be used for
1406 -- all units in the partition, including all run-time library units.
1407 -- One way to achieve this is to use the /ALL_FILES and /FORCE_COMPILE
1408 -- for gnatmake.
1409 -- This option is rarely used. One case in which it may be advantageous is
1410 -- in an application where exception raising is common and the overall
1411 -- performance of the application is improved by favoring exception
1412 -- propagation.
1416 -- /MAX_LINE_LENGTH=nnn
1417 --
1418 -- Set maximum line length.
1419 -- The length of lines must not exceed the given value nnn.
1423 -- /NOLIST (D)
1424 -- /LIST
1425 --
1426 -- Cause a full listing of the file to be generated.
1430 -- /MAPPING_FILE=file_name
1431 --
1432 -- Use mapping file file_name
1433 --
1434 -- A mapping file is a way to communicate to the compiler two mappings:
1435 -- from unit names to file names (without any directory information) and
1436 -- from file names to path names (with full directory information).
1437 -- These mappings are used by the compiler to short-circuit the path
1438 -- search.
1439 --
1440 -- The use of mapping files is not required for correct operation of the
1441 -- compiler, but mapping files can improve efficiency, particularly when
1442 -- sources are read over a slow network connection. In normal operation,
1443 -- you need not be concerned with the format or use of mapping files,
1444 -- and /MAPPING_FILE is not a qualifier that you would use explicitly.
1445 -- It is intended only for use by automatic tools such as GNAT MAKE
1446 -- running under the project file facility. The description here of the
1447 -- format of mapping files is provided for completeness and for possible
1448 -- use by other tools.
1449 --
1450 -- A mapping file is a sequence of sets of three lines. In each set, the
1451 -- first line is the unit name, in lower case, with "%s" appended for
1452 -- specifications and "%b" appended for bodies; the second line is the
1453 -- file name; and the third line is the path name.
1454 --
1455 -- Example:
1456 --
1457 -- main%b
1458 -- main.2_ada
1459 -- /gnat/project1/sources/main.2_ada
1460 --
1461 -- When qualifier ?MAPPING_FILE is specified, the compiler will create in
1462 -- memory the two mappings from the specified file. If there is any
1463 -- problem (non existent file, truncated file or duplicate entries),
1464 -- no mapping will be created.
1465 --
1466 -- Several /MAPPING_FILE qualifiers may be specified; however, only the
1467 -- last one on the command line will be taken into account.
1468 --
1469 -- When using a project file, GNAT MAKE creates a temporary mapping file
1470 -- and communicates it to the compiler using this switch.
1479 -- /MESSAGES_PROJECT_FILE[=messages-option]

1481 -- Specifies the "verbosity" of the parsing of project files.
1482 -- messages-option may be one of the following:
1483 --
1484 -- DEFAULT (D) No messages are output if there is no error or warning.
1485 --
1486 -- MEDIUM A small number of messages are output.
1487 --
1488 -- HIGH A great number of messages are output, most of them not
1489 -- being useful for the user.
1493 -- /NO_GNAT_ADC
1494 --
1495 -- Cause the compiler to ignore any configuration pragmas file GNAT.ADC
1496 -- in the default directory. Implied by qualifier /PROJECT_FILE.
1497 -- Often used in conjunction with qualifier /CONFIGURATION_PRAGMAS_FILE.
1501 -- /NOLOAD
1502 --
1503 -- Cause the compiler to operate in semantic check mode with full
1504 -- checking for all illegalities specified in the reference manual, but
1505 -- without generation of any source code (no object or ALI file
1506 -- generated).
1507 --
1508 -- Since dependent files must be accessed, you must follow the GNAT
1509 -- semantic restrictions on file structuring to operate in this mode:
1510 --
1511 -- o The needed source files must be accessible.
1512 -- o Each file must contain only one compilation unit.
1513 -- o The file name and unit name must match.
1514 --
1515 -- The output consists of error messages as appropriate. No object file
1516 -- or ALI file is generated. The checking corresponds exactly to the
1517 -- notion of legality in the Ada reference manual.
1518 --
1519 -- Any unit can be compiled in semantics-checking-only mode, including
1520 -- units that would not normally be compiled (generic library units,
1521 -- subunits, and specifications where a separate body is present).
1525 -- /NOSTD_INCLUDES
1526 --
1527 -- Do not look in the default directory for source files of the runtime.
1531 -- /NOSTD_LIBRARIES
1532 --
1533 -- Do not look for library files in the system default directory.
1548 -- /NOOPTIMIZE (D)
1549 -- /OPTIMIZE[=(keyword[,...])]
1550 --
1551 -- Selects the level of optimization for your program. The supported
1552 -- keywords are as follows:
1553 --
1554 -- ALL (D) Perform most optimizations, including those that
1555 -- may be expensive.
1556 --
1557 -- NONE Do not do any optimizations. Same as /NOOPTIMIZE.
1558 --
1559 -- SOME Perform some optimizations, but omit ones that
1560 -- are costly.
1561 --
1562 -- DEVELOPMENT Same as SOME.
1563 --
1564 -- INLINING Full optimization, and also attempt automatic inlining
1565 -- of small subprograms within a unit
1566 --
1567 -- UNROLL_LOOPS Try to unroll loops. This keyword may be specified
1568 -- with any keyword above other than NONE. Loop
1569 -- unrolling usually, but not always, improves the
1570 -- performance of programs.
1574 -- NODOC (see /OPTIMIZE)
1578 -- /NOPOLLING (D)
1579 -- /POLLING
1580 --
1581 -- Enable polling. See the description of pragma Polling in the GNAT
1582 -- Reference Manual for full details.
1586 -- /PROJECT_FILE=filename
1587 --
1588 -- Specifies the main project file to be used. The project files rooted
1589 -- at the main project file will be parsed before the invocation of the
1590 -- compiler. The source and object directories to be searched will be
1591 -- communicated to the compiler through logical names
1592 -- ADA_PRJ_INCLUDE_FILE and ADA_PRJ_OBJECTS_FILE.
1596 -- /PRINT_STANDARD
1597 --
1598 -- cause the compiler to output a representation of package Standard
1599 -- in a form very close to standard Ada. It is not quite possible to
1600 -- do this and remain entirely Standard (since new numeric base types
1601 -- cannot be created in standard Ada), but the output is easily
1602 -- readable to any Ada programmer, and is useful to determine the
1603 -- characteristics of target dependent types in package Standard.
1616 -- /NOREPORT_ERRORS (D)
1617 -- /REPORT_ERRORS[=(keyword[,...])]
1618 --
1619 -- Change the way errors are reported. The following keywords are
1620 -- supported:
1621 --
1622 -- VERBOSE (D) Verbose mode. Full error output with source lines
1623 -- to SYS$OUTPUT.
1624 --
1625 -- BRIEF Generate the brief format error messages to
1626 -- SYS$OUTPUT as well as the verbose format message or
1627 -- full listing.
1628 --
1629 -- FULL Normally, the compiler suppresses error messages that
1630 -- are likely to be redundant. This keyword causes all
1631 -- error messages to be generated. One particular effect
1632 -- is for the case of references to undefined variables.
1633 -- If a given variable is referenced several times, the
1634 -- normal format of messages produces one error. With
1635 -- FULL, each undefined reference produces a separate
1636 -- error message.
1637 --
1638 -- IMMEDIATE Normally, the compiler saves up error messages and
1639 -- generates them at the end of compilation in proper
1640 -- sequence. This keyword causes error messages to be
1641 -- generated as soon as they are detected. The use of
1642 -- IMMEDIATE usually causes error messages to be
1643 -- generated out of sequence. Use it when the compiler
1644 -- blows up due to an internal error. In this case, the
1645 -- error messages may be lost. Sometimes blowups are
1646 -- the result of mishandled error messages, so you may
1647 -- want to run with this keyword to determine whether
1648 -- any error messages were generated.
1649 --
1650 -- DEFAULT Turn off VERBOSE and BRIEF. Same as /NOREPORT_ERRORS.
1654 -- NODOC (see /REPORT_ERRORS)
1673 -- /NOREPRESENTATION_INFO (D)
1674 -- /REPRESENTATION_INFO[=(keyword[,...])]
1675 --
1676 -- This qualifier controls output from the compiler of a listing showing
1677 -- representation information for declared types and objects.
1678 --
1679 -- ARRAYS (D) Size and alignment information is listed for
1680 -- declared array and record types.
1681 --
1682 -- ARRAYS_FILE Similar to ARRAYS, but the output is to a file
1683 -- with the name 'file_rep' where 'file' is the name
1684 -- of the corresponding source file.
1685 --
1686 -- NONE no information is output (equivalent to omitting
1687 -- the /REPRESENTATION_INFO qualifiers).
1688 --
1689 -- OBJECTS Size and alignment information is listed for all
1690 -- declared types and objects.
1691 --
1692 -- OBJECTS_FILE Similar to OBJECTS, but the output is to a file
1693 -- with the name 'file_rep' where 'file' is the name
1694 -- of the corresponding source file.
1695 --
1696 -- SYMBOLIC Symbolic expression information for values that
1697 -- are computed at run time for variant records.
1698 --
1699 -- SYMBOLIC_FILE Similar to SYMBOLIC, but the output is to a file
1700 -- with the name 'file_rep' where 'file' is the name
1701 -- of the corresponding source file.
1702 --
1703 -- DEFAULT Equivalent to ARRAYS.
1707 -- NODOC (see /REPRESENTATION_INFO)
1711 -- /RUNTIME_SYSTEM=xxx
1712 --
1713 -- Build against an alternate runtime system named xxx or RTS-xxx.
1717 -- /SEARCH=(directory[,...])
1718 --
1719 -- When looking for source files also look in directories specified.
1778 -- /NOSTYLE_CHECKS (D)
1779 -- /STYLE_CHECKS[=(keyword,[...])]
1780 --
1781 -- Normally, GNAT permits any code layout consistent with the reference
1782 -- manual requirements. This qualifier imposes style checking on the
1783 -- input source code. The following keywords are supported:
1784 --
1785 -- ALL_BUILTIN (D) Equivalent to the following list of options:
1786 -- 3, ATTRIBUTE, BLANKS, COMMENTS, END, VTABS,
1787 -- HTABS, IF_THEN, KEYWORD, LAYOUT, LINE_LENGTH,
1788 -- PRAGMA, REFERENCES, SPECS, TOKEN.
1789 --
1790 -- 1 .. 9 Specify indentation level from 1 to 9.
1791 -- The general style of required indentation is as
1792 -- specified by the examples in the Ada Reference
1793 -- Manual. Full line comments must be aligned with
1794 -- the -- starting on a column that is a multiple
1795 -- of the alignment level.
1796 --
1797 -- ATTRIBUTE Check attribute casing.
1798 -- Attribute names, including the case of keywords
1799 -- such as digits used as attributes names,
1800 -- must be written in mixed case, that is,
1801 -- the initial letter and any letter following an
1802 -- underscore must be uppercase.
1803 -- All other letters must be lowercase.
1804 --
1805 -- BLANKS Blanks not allowed at statement end.
1806 -- Trailing blanks are not allowed at the end of
1807 -- statements. The purpose of this rule, together
1808 -- with option HTABS (no horizontal tabs), is to
1809 -- enforce a canonical format for the use of
1810 -- blanks to separate source tokens.
1811 --
1812 -- COMMENTS Check comments.
1813 -- Comments must meet the following set of rules:
1814 --
1815 -- * The "--" that starts the column must either
1816 -- start in column one, or else at least one
1817 -- blank must precede this sequence.
1818 --
1819 -- * Comments that follow other tokens on a line
1820 -- must have at least one blank following the
1821 -- "--" at the start of the comment.
1822 --
1823 -- * Full line comments must have two blanks
1824 -- following the "--" that starts the comment,
1825 -- with the following exceptions.
1826 --
1827 -- * A line consisting only of the "--"
1828 -- characters, possibly preceded by blanks is
1829 -- permitted.
1830 --
1831 -- * A comment starting with "--x" where x is
1832 -- a special character is permitted. This
1833 -- allows proper processing of the output
1834 -- generated by specialized tools including
1835 -- gnatprep (where --! is used) and the SPARK
1836 -- annnotation language (where --# is used).
1837 -- For the purposes of this rule, a special
1838 -- character is defined as being in one of the
1839 -- ASCII ranges 16#21#..16#2F# or
1840 -- 16#3A#..16#3F#.
1841 --
1842 -- * A line consisting entirely of minus signs,
1843 -- possibly preceded by blanks, is permitted.
1844 -- This allows the construction of box
1845 -- comments where lines of minus signs are
1846 -- used to form the top and bottom of the box.
1847 --
1848 -- * If a comment starts and ends with "--" is
1849 -- permitted as long as at least one blank
1850 -- follows the initial "--". Together with
1851 -- the preceding rule, this allows the
1852 -- construction of box comments, as shown in
1853 -- the following example:
1854 --
1855 --
1856 -- ---------------------------
1857 -- -- This is a box comment --
1858 -- -- with two text lines. --
1859 -- ---------------------------
1860 --
1861 -- END Check end/exit labels.
1862 -- Optional labels on end statements ending
1863 -- subprograms and on exit statements exiting
1864 -- named loops, are required to be present.
1865 --
1866 -- GNAT Enforces a set of style conventions that
1867 -- correspond to the style used in the GNAT
1868 -- source code. All compiler units are always
1869 -- compile with this keyword specified.
1870 --
1871 -- You can find the full documentation for the
1872 -- style conventions imposed by this keyword
1873 -- in the body of the package "Style" in the
1874 -- compiler sources.
1875 --
1876 -- You should not normally use this keyword.
1877 -- However, you MUST use it for compiling any
1878 -- language-defined unit, or for adding children
1879 -- to any language-defined unit other than
1880 -- "Standard".
1881 --
1882 -- HTABS No horizontal tabs.
1883 -- Horizontal tab characters are not permitted in
1884 -- the source text. Together with the BLANKS
1885 -- (no blanks at end of line) option, this
1886 -- enforces a canonical form for the use of blanks
1887 -- to separate source tokens.
1888 --
1889 -- IF_THEN Check if-then layout.
1890 -- The keyword then must appear either on the
1891 -- same line as the corresponding if, or on a line
1892 -- on its own, lined up under the if with at least
1893 -- one non-blank line in between containing all or
1894 -- part of the condition to be tested.
1895 --
1896 -- KEYWORD Check keyword casing.
1897 -- All keywords must be in lower case (with the
1898 -- exception of keywords such as digits used as
1899 -- attribute names to which this check does not
1900 -- apply).
1901 --
1902 -- LAYOUT Check layout.
1903 -- Layout of statement and declaration constructs
1904 -- must follow the recommendations in the Ada
1905 -- Reference Manual, as indicated by the form of
1906 -- the syntax rules. For example an else keyword
1907 -- must be lined up with the corresponding if
1908 -- keyword.
1909 --
1910 -- There are two respects in which the style rule
1911 -- enforced by this check option are more liberal
1912 -- than those in the Ada Reference Manual.
1913 -- First in the case of record declarations,
1914 -- it is permissible to put the record keyword on
1915 -- the same line as the type keyword, and then
1916 -- the end in end record must line up under type.
1917 -- For example, either of the following two
1918 -- layouts is acceptable:
1919 --
1920 -- type q is record
1921 -- a : integer;
1922 -- b : integer;
1923 -- end record;
1924 --
1925 -- type q is
1926 -- record
1927 -- a : integer;
1928 -- b : integer;
1929 -- end record;
1930 --
1931 -- Second, in the case of a block statement,
1932 -- a permitted alternative is to put the block
1933 -- label on the same line as the declare or begin
1934 -- keyword, and then line the end keyword up under
1935 -- the block label. For example both the following
1936 -- are permitted:
1937 --
1938 --
1939 --
1940 -- Block : declare
1941 -- A : Integer := 3;
1942 -- begin
1943 -- Proc (A, A);
1944 -- end Block;
1945 --
1946 -- Block :
1947 -- declare
1948 -- A : Integer := 3;
1949 -- begin
1950 -- Proc (A, A);
1951 -- end Block;
1952 --
1953 -- The same alternative format is allowed for
1954 -- loops. For example, both of the following are
1955 -- permitted:
1956 --
1957 --
1958 --
1959 -- Clear : while J < 10 loop
1960 -- A (J) := 0;
1961 -- end loop Clear;
1962 --
1963 -- Clear :
1964 -- while J < 10 loop
1965 -- A (J) := 0;
1966 -- end loop Clear;
1967 --
1968 --
1969 --
1970 -- LINE_LENGTH Check maximum line length.
1971 -- The length of source lines must not exceed 79
1972 -- characters, including any trailing blanks
1973 -- The value of 79 allows convenient display on
1974 -- an 80 character wide device or window, allowing
1975 -- for possible special treatment of 80 character
1976 -- lines.
1977 --
1978 -- ORDERED_SUBPROGRAMS Check order of subprogram bodies.
1979 -- All subprogram bodies in a given scope (e.g.
1980 -- a package body) must be in alphabetical order.
1981 -- The ordering rule uses normal Ada rules for
1982 -- comparing strings, ignoring casing of letters,
1983 -- except that if there is a trailing numeric
1984 -- suffix, then the value of this suffix is used
1985 -- in the ordering (e.g. Junk2 comes before
1986 -- Junk10).
1987 --
1988 -- NONE The default behavior. Same as /NOSTYLE_CHECKS.
1989 --
1990 -- PRAGMA Check pragma casing.
1991 -- Pragma names must be written in mixed case,
1992 -- that is, the initial letter and any letter
1993 -- following an underscore must be uppercase.
1994 -- All other letters must be lowercase.
1995 --
1996 -- REFERENCES Check references.
1997 -- All identifier references must be cased in the
1998 -- same way as the corresponding declaration.
1999 -- No specific casing style is imposed on
2000 -- identifiers. The only requirement is for
2001 -- consistency of references with declarations.
2002 --
2003 -- RM_COLUMN_LAYOUT Enforce the layout conventions suggested by
2004 -- the examples and syntax rules of the Ada
2005 -- Language Reference Manual. For example, an
2006 -- "else" must line up with an "if" and code in
2007 -- the "then" and "else" parts must be indented.
2008 -- The compiler considers violations of the
2009 -- layout rules a syntax error if you specify
2010 -- this keyword.
2011 --
2012 -- SPECS Check separate specs.
2013 -- Separate declarations ("specs") are required
2014 -- for subprograms (a body is not allowed to serve
2015 -- as its own declaration). The only exception is
2016 -- that parameterless library level procedures are
2017 -- not required to have a separate declaration.
2018 -- This exception covers the most frequent form of
2019 -- main program procedures.
2020 --
2021 -- STANDARD_CASING Check casing of entities in Standard.
2022 -- Any identifier from Standard must be cased to
2023 -- match the presentation in the Ada Reference
2024 -- Manual (for example, Integer and ASCII.NUL).
2025 --
2026 -- TOKEN Check token spacing.
2027 -- The following token spacing rules are enforced:
2028 --
2029 -- * The keywords abs and not must be followed
2030 -- by a space.
2031 --
2032 -- * The token => must be surrounded by spaces.
2033 --
2034 -- * The token <> must be preceded by a space or
2035 -- a left parenthesis.
2036 --
2037 -- * Binary operators other than ** must be
2038 -- surrounded by spaces. There is no
2039 -- restriction on the layout of the ** binary
2040 -- operator.
2041 --
2042 -- * Colon must be surrounded by spaces.
2043 --
2044 -- * Colon-equal (assignment) must be surrounded
2045 -- by spaces.
2046 --
2047 -- * Comma must be the first non-blank character
2048 -- on the line, or be immediately preceded by
2049 -- a non-blank character, and must be followed
2050 -- by a space.
2051 --
2052 -- * If the token preceding a left paren ends
2053 -- with a letter or digit, then a space must
2054 -- separate the two tokens.
2055 --
2056 -- * A right parenthesis must either be the
2057 -- first non-blank character on a line, or it
2058 -- must be preceded by a non-blank character.
2059 --
2060 -- * A semicolon must not be preceded by
2061 -- a space, and must not be followed by
2062 -- a non-blank character.
2063 --
2064 -- * A unary plus or minus may not be followed
2065 -- by a space.
2066 --
2067 -- * A vertical bar must be surrounded by
2068 -- spaces.
2069 --
2070 -- In the above rules, appearing in column one is
2071 -- always permitted, that is, counts as meeting
2072 -- either a requirement for a required preceding
2073 -- space, or as meeting a requirement for no
2074 -- preceding space.
2075 --
2076 -- Appearing at the end of a line is also always
2077 -- permitted, that is, counts as meeting either
2078 -- a requirement for a following space,
2079 -- or as meeting a requirement for no following
2080 -- space.
2081 --
2082 -- VTABS No form feeds or vertical tabs.
2083 -- Form feeds or vertical tab characters are not
2084 -- permitted in the source text.
2088 -- NODOC (see /STYLE_CHECKS)
2092 -- /SYMBOL_PREPROCESSING="symbol=value"
2093 --
2094 -- Define or redefine a preprocessing symbol, associated with value.
2095 -- If "=value" is not specified, then the value of the symbol is True.
2096 -- A symbol is an identifier, following normal Ada (case-insensitive)
2097 -- rules for its syntax, and value is any sequence (including an empty
2098 -- sequence) of characters from the set (letters, digits, period,
2099 -- underline). Ada reserved words may be used as symbols, with the
2100 -- exceptions of "if", "else", "elsif", "end", "and", "or" and "then".
2101 --
2102 -- A symbol declared with this qualifier on the command line replaces
2103 -- a symbol with the same name either in a definition file or specified
2104 -- with a switch -D in the preprocessor data file.
2105 --
2106 -- This qualifier is similar to qualifier /ASSOCIATE of
2107 -- GNAT PREPROCESSING.
2111 -- /NOSYNTAX_ONLY (D)
2112 -- /SYNTAX_ONLY
2113 --
2114 -- Run GNAT in syntax checking only mode. You can check a series of
2115 -- files in a single command, and can use wild cards to specify such a
2116 -- group of files.
2117 --
2118 -- You may use other qualifiers in conjunction with this qualifier. In
2119 -- particular, /LIST and /REPORT_ERRORS=VERBOSE are useful to control the
2120 -- format of any generated error messages.
2121 --
2122 -- The output is simply the error messages, if any. No object file or ALI
2123 -- file is generated by a syntax-only compilation. Also, no units other
2124 -- than the one specified are accessed. For example, if a unit "X" with's
2125 -- a unit "Y", compiling unit "X" in syntax check only mode does not
2126 -- access the source file containing unit "Y".
2127 --
2128 -- Normally, GNAT allows only a single unit in a source file. However,
2129 -- this restriction does not apply in syntax-check-only mode, and it is
2130 -- possible to check a file containing multiple compilation units
2131 -- concatenated together. This is primarily used by the GNAT CHOP
2132 -- command.
2136 -- /TABLE_MULTIPLIER=nnn
2137 --
2138 -- All compiler tables start at nnn times usual starting size.
2142 -- /TRACE_UNITS
2143 -- /NOTRACE_UNITS
2144 --
2145 -- This switch that does for the frontend what /VERBOSE does for the
2146 -- backend. The system prints the name of each unit, either a compilation
2147 -- unit or nested unit, as it is being analyzed.
2151 -- /TREE_OUTPUT
2152 -- /NOTREE_OUTPUT
2153 --
2154 -- Cause GNAT to write the internal tree for a unit to a file (with the
2155 -- filetype ATB for a body or ATS for a spec). This is not normally
2156 -- required, but is used by separate analysis tools. Typically these
2157 -- tools do the necessary compilations automatically, so you should never
2158 -- have to specify this switch in normal operation.
2162 -- /TRY_SEMANTICS
2163 -- /NOTRY_SEMANTICS
2164 --
2165 -- In normal operation mode the compiler first parses the program and
2166 -- determines if there are any syntax errors. If there are, appropriate
2167 -- error messages are generated and compilation is immediately
2168 -- terminated. This qualifier tells GNAT to continue with semantic
2169 -- analysis even if syntax errors have been found. This may enable the
2170 -- detection of more errors in a single run. On the other hand, the
2171 -- semantic analyzer is more likely to encounter some internal fatal
2172 -- error when given a syntactically invalid tree.
2176 -- /NOUNITS_LIST (D)
2177 -- /UNITS_LIST
2178 --
2179 -- Print a list of units required by this compilation on SYS$OUTPUT. The
2180 -- listing includes all units on which the unit being compiled depends
2181 -- either directly or indirectly.
2185 -- /NOUNIQUE_ERROR_TAG (D)
2186 -- /UNIQUE_ERROR_TAG
2187 --
2188 -- Tag compiler error messages with the string "error: ".

2486 -- MODIFIED_UNREF Activates warnings for variables that are
2487 -- assigned (using an initialization value or with
2488 -- one or more assignment statements) but whose
2489 -- value is never read. The warning is suppressed
2490 -- for volatile variables and also for variables

2498 -- NORMAL Sets normal warning mode, in which enabled
2499 -- warnings are issued and treated as warnings
2500 -- rather than errors. This is the default mode.
2501 -- It can be used to cancel the effect of an

2504 -- of the implicit /WARNINGS=ERRORS that is
2505 -- activated by the use of /STYLE=GNAT.
2506 --
2507 -- OBSOLESCENT Activates warnings for calls to subprograms
2508 -- marked with pragma Obsolescent and for use of
2509 -- features in Annex J of the Ada Reference
2510 -- Manual. In the case of Annex J, not all
2511 -- features are flagged. In particular use of the
2512 -- renamed packages (like Text_IO), use of package
2513 -- ASCII and use of the attribute 'Constrained are
2514 -- not flagged, since these are very common and
2515 -- would generate many annoying positive warnings.
2516 -- The default is that such warnings are not

2574 --
2575 -- UNREFERENCED_FORMALS Activate warnings on unreferenced formals.
2576 -- Causes a warning to be generated if a formal

2579 -- on using option ALL or UNUSED.
2580 --
2581 -- NOUNREFERENCED_FORMALS Suppress warnings on unreferenced formals.
2582 -- Suppresses warnings for unreferenced formal
2583 -- parameters. Note that the combination UNUSED
2584 -- followed by NOUNREFERENCED_FORMALS has the
2585 -- effect of warning on unreferenced entities
2586 -- other than subprogram formals.
2587 --
2588 -- UNUSED Activates warnings to be generated for entities
2589 -- that are defined but not referenced, and for
2590 -- units that are with'ed and not referenced. In
2591 -- the case of packages, a warning is also
2592 -- generated if no entities in the package are
2593 -- referenced. This means that if the package
2594 -- is referenced but the only references are in
2595 -- use clauses or renames declarations, a warning
2596 -- is still generated. A warning is also generated
2597 -- for a generic package that is with'ed but never
2598 -- instantiated. In the case where a package or
2599 -- subprogram body is compiled, and there is a
2600 -- with on the corresponding spec that is only
2601 -- referenced in the body, a warning is also
2602 -- generated, noting that the with can be moved

2644 -- /NOWIDE_CHARACTER_ENCODING (D)
2645 -- /WIDE_CHARACTER_ENCODING[=encode-type]
2646 --
2647 -- Specifies the mechanism used to encode wide characters. 'encode-type'
2648 -- is one of the following:
2649 --
2650 -- BRACKETS (D) A wide character is encoded as ["xxxx"] where XXXX
2651 -- are four hexadecimal digits representing the coding
2652 -- ('Pos value) of the character in type
2653 -- Wide_Character. The hexadecimal digits may use upper
2654 -- or lower case letters.
2655 --
2656 -- This notation can also be used for upper half
2657 -- Character values using the format ["xx"] where XX is
2658 -- two hexadecimal digits representing the coding ('Pos
2659 -- value) of the character in type Character (or
2660 -- Wide_Character). The hexadecimal digits may use upper
2661 -- of lower case.
2662 --
2663 -- NONE No wide characters are allowed. Same
2664 -- as /NOWIDE_CHARCTER_ENCODING.
2665 --
2666 -- HEX In this encoding, a wide character is represented by
2667 -- the following five character sequence: ESC a b c d
2668 -- Where 'a', 'b', 'c', and 'd' are the four hexadecimal
2669 -- characters (using uppercase letters) of the wide
2670 -- character code. For example, ESC A345 is used to
2671 -- represent the wide character with code 16#A345#. This
2672 -- scheme is compatible with use of the full
2673 -- Wide_Character set.
2674 --
2675 -- UPPER The wide character with encoding 16#abcd# where the
2676 -- upper bit is on (in other words, "a" is in the range
2677 -- 8-F) is represented as two bytes, 16#ab# and 16#cd#.
2678 -- The second byte may never be a format control
2679 -- character, but is not required to be in the upper
2680 -- half. This method can be also used for shift-JIS or
2681 -- EUC, where the internal coding matches the external
2682 -- coding.
2683 --
2684 -- SHIFT_JIS A wide character is represented by a two-character
2685 -- sequence, 16#ab# and 16#cd#, with the restrictions
2686 -- described for upper-half encoding as described above.
2687 -- The internal character code is the corresponding JIS
2688 -- character according to the standard algorithm for
2689 -- Shift-JIS conversion. Only characters defined in the
2690 -- JIS code set table can be used with this encoding
2691 -- method.
2692 --
2693 -- UTF8 A wide character is represented using
2694 -- UCS Transformation Format 8 (UTF-8) as defined in Annex
2695 -- R of ISO 10646-1/Am.2. Depending on the character
2696 -- value, the representation is a one, two, or three byte
2697 -- sequence:
2698 --
2699 -- 16#0000#-16#007f#: 2#0xxxxxxx#
2700 -- 16#0080#-16#07ff#: 2#110xxxxx# 2#10xxxxxx#
2701 -- 16#0800#-16#ffff#: 2#1110xxxx# 2#10xxxxxx# 2#10xxxxxx#
2702 --
2703 -- where the xxx bits correspond to the left-padded bits
2704 -- of the the 16-bit character value. Note that all lower
2705 -- half ASCII characters are represented as ASCII bytes
2706 -- and all upper half characters and other wide characters
2707 -- are represented as sequences of upper-half (The full
2708 -- UTF-8 scheme allows for encoding 31-bit characters as
2709 -- 6-byte sequences, but in this implementation, all UTF-8
2710 -- sequences of four or more bytes length will be treated
2711 -- as illegal).
2712 --
2713 -- EUC A wide character is represented by a two-character
2714 -- sequence 16#ab# and 16#cd#, with both characters being
2715 -- in the upper half. The internal character code is the
2716 -- corresponding JIS character according to the EUC
2717 -- encoding algorithm. Only characters defined in the JIS
2718 -- code set table can be used with this encoding method.
2722 -- NODOC (see /WIDE_CHARACTER_ENCODING)
2726 -- /NOXDEBUG (D)
2727 -- /XDEBUG
2728 --
2729 -- Output expanded source files for source level debugging.
2730 -- The expanded source (see /EXPAND_SOURCE) is written to files
2731 -- with names formed by appending "_DG" to the input file name,
2732 -- The debugging information generated by the /DEBUG qualifier will then

2734 -- the generated code which is sometimes useful for complex code, for
2735 -- example to find out exactly which part of a complex construction
2736 -- raised an exception.
2743 -- /XREF[=keyword]
2744 --
2745 -- Normally the compiler generates full cross-referencing information in

3514 --

3518 -- o Compile
3519 -- o Bind

3521 --
3522 --
3523 -- You may specify one or more of the following keywords to the /ACTIONS
3524 -- qualifier:
3525 --
3526 -- BIND Bind only. Can be combined with /ACTIONS=COMPILE
3527 -- to do compilation and binding, but no linking.
3528 -- Can be combined with /ACTIONS=LINK to do binding and
3529 -- linking. When not combined with /ACTIONS=COMPILE,
3530 -- all the units in the closure of the main program must
3531 -- have been previously compiled and must be up to date.
3532 --
3533 -- COMPILE Compile only. Do not perform binding, except when
3534 -- /ACTIONS=BIND is also specified. Do not perform
3535 -- linking, except if both /ACTIONS=BIND and /ACTIONS=LINK
3536 -- are also specified.
3537 --
3538 -- LINK Link only. Can be combined with /ACTIONS=BIND to do
3539 -- binding and linking. Linking will not be performed
3540 -- if combined with /ACTIONS=COMPILE but not with
3541 -- /ACTIONS=BIND\. When not combined with /ACTIONS=BIND
3542 -- all the units in the closure of the main program must
3543 -- have been previously compiled and must be up to date,
3544 -- and the main program need to have been bound.
3548 -- /NOALL_FILES (D)
3549 -- /ALL_FILES
3550 --
3551 -- Consider all files in the make process, even the GNAT internal system
3552 -- files (for example, the predefined Ada library files). By default,
3553 -- GNAT MAKE does not check these files (however, if there is an
3554 -- installation problem, it will be caught when GNAT MAKE binds your
3555 -- program). You may have to specify this qualifier if you are working on
3556 -- GNAT itself. The vast majority of GNAT MAKE users never need to
3557 -- specify this switch. All GNAT internal files with will be compiled
3558 -- with /STYLE_CHECK=GNAT.
3562 -- /NOALL_PROJECTS (D)

3616 -- Check if all objects are up to date. If they are, output the object
3617 -- dependences to SYS$OUTPUT in a form that can be directly exploited in
3618 -- a Unix-style Makefile. By default, each source file is prefixed with
3619 -- its (relative or absolute) directory name. This name is whatever you
3620 -- specified in the various /SOURCE_SEARCH and /SEARCH qualifiers. If
3621 -- you also speficy the /QUIET qualifier, only the source file names,
3622 -- without relative paths, are output. If you just specify the
3623 -- /DEPENDENCY_LIST qualifier, dependencies of the GNAT internal system
3624 -- files are omitted. This is typically what you want. If you also
3625 -- specify the /ALL_FILES qualifier, dependencies of the GNAT internal
3626 -- files are also listed. Note that dependencies of the objects in
3627 -- external Ada libraries (see the /SKIP_MISSING qualifier) are never
3628 -- reported.
3632 -- /DIRECTORY_OBJECTS=<file>

3634 -- Put all object files and .ALI files in <file>.
3635 -- This qualifier is not compatible with /PROJECT_FILE.
3639 -- /NODO_OBJECT_CHECK (D)
3640 -- /DO_OBJECT_CHECK
3641 --
3642 -- Don't compile, bind, or link. Output a single command that will
3643 -- recompile an out of date unit, if any. Repeated use of this option,
3644 -- followed by carrying out the indicated compilation, will eventually
3645 -- result in recompiling all required units.
3646 --
3647 -- If any ALI is missing during the process, GNAT MAKE halts and
3648 -- displays an error message.
3652 -- /EXECUTABLE=exec-name
3653 --
3654 -- The name of the final executable program will be 'exec_name'. If this

3661 -- /EXTERNAL_REFERENCE="name=val"
3662 --
3663 -- Specifies an external reference to the project manager. Useful only if

3680 -- /NOFULL_PATH_IN_BRIEF_MESSAGES (D)
3681 -- /FULL_PATH_IN_BRIEF_MESSAGES
3682 --
3683 -- When using project files, if some errors or warnings are detected

3690 -- /NOIN_PLACE (D)
3691 -- /IN_PLACE
3692 --
3693 -- In normal mode, GNAT MAKE compiles all object files and ALI files
3694 -- into the current directory. If the /IN_PLACE switch is used,
3695 -- then instead object files and ALI files that already exist are over-
3696 -- written in place. This means that once a large project is organized
3697 -- into separate directories in the desired manner, then GNAT MAKE will
3698 -- automatically maintain and update this organization. If no ALI files
3699 -- are found on the Ada object path, the new object and ALI files are

3721 -- Any qualifiers specified after this qualifier other than
3722 -- /COMPILER_QUALIFIERS, /BINDER_QUALIFIERS and /LINKER_QUALIFIERS
3723 -- are for the benefit of GNAT MAKE itself.
3727 -- /NOMAPPING (D)
3728 -- /MAPPING
3729 --
3730 -- Use a mapping file. A mapping file is a way to communicate to the
3731 -- compiler two mappings: from unit names to file names (without any
3732 -- directory information) and from file names to path names (with full
3733 -- directory information). These mappings are used by the compiler to
3734 -- short-circuit the path search. When GNAT MAKE is invoked with this
3735 -- qualifier, it will create a mapping file, initially populated by the
3736 -- project manager, if /PROJECT_File= is used, otherwise initially empty.
3737 -- Each invocation of the compiler will add the newly accessed sources to
3738 -- the mapping file. This will improve the source search during the next
3739 -- invocations of the compiler
3748 -- /MESSAGES_PROJECT_FILE[=messages-option]
