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
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
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 :=
71 -- The syntax of a qualifier delaration is as follows:
73 -- SWITCH_STRING ::= "/ command-qualifier-name TRANSLATION"
77 -- | DIRECTORIES_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
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:
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:
172 -- An implicit qualifier definition is created:
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
182 type String_Ptr is access constant String;
183 -- String pointer type used throughout
185 type Switches is array (Natural range <>) of String_Ptr;
186 -- Type used for array of swtiches
188 type Switches_Ptr is access constant Switches;

1951 -- There are two respects in which the style rule

1953 -- than those in the Ada Reference Manual.
1954 -- First in the case of record declarations,
1955 -- it is permissible to put the record keyword on

1973 -- a permitted alternative is to put the block
1974 -- label on the same line as the declare or begin

2042 -- No specific casing style is imposed on
2043 -- identifiers. The only requirement is for
2044 -- consistency of references with declarations.
2046 -- RM_COLUMN_LAYOUT Enforce the layout conventions suggested by

2052 -- layout rules a syntax error if you specify
2055 -- SPECS Check separate specs.

2058 -- as its own declaration). The only exception is
2059 -- that parameterless library level procedures are
2060 -- not required to have a separate declaration.

2432 -- defined in the reference manual, the compiler detects two kinds of
2433 -- warning situations. First, the compiler considers some constructs
2434 -- suspicious and generates a warning message to alert you to a possible
2435 -- error. Second, if the compiler detects a situation that is sure to
2436 -- raise an exception at runtime, it generates a warning message.
2438 -- You may specify the following keywords to change this behavior:
2440 -- DEFAULT (D) The default behavior above.

2455 -- that can be activated by option ALL.
2457 -- ALL_GCC Request additional messages from the GCC
2458 -- backend. Most of these are not relevant
2461 -- CONDITIONALS Activate warnings for conditional
2462 -- Expressions used in tests that are known
2463 -- to be True or False at compile time. The
2464 -- default is that such warnings are not
2467 -- NOCONDITIONALS Suppress warnings for conditional
2468 -- expressions used in tests that are known
2469 -- to be True or False at compile time.
2471 -- IMPLICIT_DEREFERENCE Activate warnings on implicit dereferencing.
2472 -- The use of a prefix of an access type in an
2473 -- indexed component, slice, or selected component
2474 -- without an explicit .all will generate
2475 -- a warning. With this warning enabled, access
2476 -- checks occur only at points where an explicit
2477 -- .all appears in the source code (assuming no

2484 -- in indexed components, slices, and selected
2487 -- ELABORATION Activate warnings on missing pragma
2488 -- Elaborate_All statements. The default is
2489 -- that such warnings are not generated.
2491 -- NOELABORATION Suppress warnings on missing pragma
2492 -- Elaborate_All statements.
2494 -- ERRORS Warning messages are to be treated as errors.
2495 -- The warning string still appears, but the
2496 -- warning messages are counted as errors, and
2497 -- prevent the generation of an object file.
2499 -- HIDING Activate warnings on hiding declarations.
2500 -- A declaration is considered hiding if it is
2501 -- for a non-overloadable entity, and it declares
2502 -- an entity with the same name as some other
2503 -- entity that is directly or use-visible. The
2504 -- default is that such warnings are not
2507 -- NOHIDING Suppress warnings on hiding declarations.
2509 -- IMPLEMENTATION Activate warnings for a with of an internal
2510 -- GNAT implementation unit, defined as any unit
2511 -- from the Ada, Interfaces, GNAT, DEC or

2524 -- Activates warnings for failure of front end
2525 -- inlining (activated by /INLINE=FULL) to inline
2526 -- a particular call. There are many reasons for
2527 -- not being able to inline a call, including most
2528 -- commonly that the call is too complex to
2529 -- inline. This warning can also be turned on
2530 -- using /INLINE=FULL.
2532 -- NOINEFFECTIVE_INLINE Suppress warnings on ineffective pragma Inlines
2533 -- Suppresses warnings on ineffective pragma
2534 -- Inlines. If the inlining mechanism cannot
2535 -- inline a call, it will simply ignore the
2536 -- request silently.
2538 -- MODIFIED_UNREF Activates warnings for variables that are
2539 -- assigned (using an initialization value or with
2540 -- one or more assignment statements) but whose
2541 -- value is never read. The warning is suppressed
2542 -- for volatile variables and also for variables
2543 -- that are renamings of other variables or for
2544 -- which an address clause is given. This warning
2545 -- can also be turned on using /WARNINGS/OPTIONAL.
2547 -- NOMODIFIED_UNREF Disables warnings for variables that are
2548 -- assigned or initialized, but never read.
2550 -- NORMAL Sets normal warning mode, in which enabled
2551 -- warnings are issued and treated as warnings
2552 -- rather than errors. This is the default mode.
2553 -- It can be used to cancel the effect of an
2554 -- explicit /WARNINGS=SUPPRESS or
2555 -- /WARNINGS=ERRORS. It also cancels the effect
2556 -- of the implicit /WARNINGS=ERRORS that is
2557 -- activated by the use of /STYLE=GNAT.
2559 -- OBSOLESCENT Activates warnings for calls to subprograms
2560 -- marked with pragma Obsolescent and for use of
2561 -- features in Annex J of the Ada Reference
2562 -- Manual. In the case of Annex J, not all
2563 -- features are flagged. In particular use of the
2564 -- renamed packages (like Text_IO), use of package
2565 -- ASCII and use of the attribute 'Constrained are
2566 -- not flagged, since these are very common and
2567 -- would generate many annoying positive warnings.
2568 -- The default is that such warnings are not
2571 -- NOOBSOLESCENT Disables warnings on use of obsolescent
2574 -- OPTIONAL Activate all optional warning messages.
2575 -- See other options under this qualifier
2576 -- for details on optional warning messages
2577 -- that can be individually controlled. The
2578 -- one exception is that /WARNINGS=OPTIONAL
2579 -- doesn't activate warnings for hiding
2580 -- variables (/WARNINGS=HIDING), so if this
2581 -- warning is required it must be explicitly
2584 -- NOOPTIONAL Suppress all optional warning messages.
2585 -- See other options under this qualifier
2586 -- for details on optional warning messages
2587 -- that can be individually controlled.
2589 -- OVERLAYS Activate warnings for possibly unintended
2590 -- initialization effects of defining address
2591 -- clauses that cause one variable to overlap
2592 -- another. The default is that such warnings
2595 -- NOOVERLAYS Suppress warnings on possibly unintended
2596 -- initialization effects of defining address
2597 -- clauses that cause one variable to overlap
2600 -- REDUNDANT Activate warnings for redundant constructs.
2601 -- In particular assignments of a variable to
2602 -- itself, and a type conversion that converts
2603 -- an object to its own type. The default
2604 -- is that such warnings are not generated.
2606 -- NOREDUNDANT Suppress warnings for redundant constructs.
2608 -- SUPPRESS Completely suppresse the output of all warning
2609 -- messages. Same as /NOWARNINGS.
2611 -- UNCHECKED_CONVERSIONS Activates warnings on unchecked conversions.
2612 -- Causes warnings to be generated for
2613 -- unchecked conversions when the two types are
2614 -- known at compile time to have different sizes.
2615 -- The default is that such warnings are
2618 -- NOUNCHECKED_CONVERSIONS Suppress warnings for unchecked conversions.
2620 -- UNINITIALIZED Generate warnings for uninitialized variables.

2627 -- UNREFERENCED_FORMALS Activate warnings on unreferenced formals.
2628 -- Causes a warning to be generated if a formal
2629 -- parameter is not referenced in the body of
2630 -- the subprogram. This warning can also be turned
2631 -- on using option ALL or UNUSED.
2633 -- NOUNREFERENCED_FORMALS Suppress warnings on unreferenced formals.
2634 -- Suppresses warnings for unreferenced formal
2635 -- parameters. Note that the combination UNUSED
2636 -- followed by NOUNREFERENCED_FORMALS has the
2637 -- effect of warning on unreferenced entities
2638 -- other than subprogram formals.
2640 -- UNUSED Activates warnings to be generated for entities
2641 -- that are defined but not referenced, and for
2642 -- units that are with'ed and not referenced. In
2643 -- the case of packages, a warning is also
2644 -- generated if no entities in the package are
2645 -- referenced. This means that if the package
2646 -- is referenced but the only references are in
2647 -- use clauses or renames declarations, a warning
2648 -- is still generated. A warning is also generated
2649 -- for a generic package that is with'ed but never
2650 -- instantiated. In the case where a package or
2651 -- subprogram body is compiled, and there is a
2652 -- with on the corresponding spec that is only
2653 -- referenced in the body, a warning is also
2654 -- generated, noting that the with can be moved
2655 -- to the body. The default is that such warnings
2656 -- are not generated.
2658 -- NOUNUSED Suppress warnings for unused entities and
2661 -- VARIABLES_UNINITIALIZED Activates warnings on unassigned variables.
2662 -- Causes warnings to be generated when a variable
2663 -- is accessed which may not be properly

2720 -- Where 'a', 'b', 'c', and 'd' are the four hexadecimal
2721 -- characters (using uppercase letters) of the wide
2722 -- character code. For example, ESC A345 is used to
2723 -- represent the wide character with code 16#A345#. This
2724 -- scheme is compatible with use of the full
2725 -- Wide_Character set.
2727 -- UPPER The wide character with encoding 16#abcd# where the
2728 -- upper bit is on (in other words, "a" is in the range

2730 -- The second byte may never be a format control
