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;

2014 -- All identifier references must be cased in the
2015 -- same way as the corresponding declaration.

2017 -- identifiers. The only requirement is for
2018 -- consistency of references with declarations.
2020 -- RM_COLUMN_LAYOUT Enforce the layout conventions suggested by

2509 -- which an address clause is given. This warning
2510 -- can also be turned on using /WARNINGS/OPTIONAL.
2512 -- NOMODIFIED_UNREF Disables warnings for variables that are

2525 -- marked with pragma Obsolescent and for use of
2526 -- features in Annex J of the Ada Reference
2527 -- Manual. In the case of Annex J, not all
2528 -- features are flagged. In particular use of the
2529 -- renamed packages (like Text_IO), use of package
2530 -- ASCII and use of the attribute 'Constrained are
2531 -- not flagged, since these are very common and
2532 -- would generate many annoying positive warnings.

2573 -- SUPPRESS Completely suppresse the output of all warning
2574 -- messages. Same as /NOWARNINGS.
2576 -- UNCHECKED_CONVERSIONS Activates warnings on unchecked conversions.
2577 -- Causes warnings to be generated for

2599 -- Suppresses warnings for unreferenced formal
2600 -- parameters. Note that the combination UNUSED
2601 -- followed by NOUNREFERENCED_FORMALS has the
2602 -- effect of warning on unreferenced entities

2605 -- UNUSED Activates warnings to be generated for entities
2606 -- that are defined but not referenced, and for
2607 -- units that are with'ed and not referenced. In
2608 -- the case of packages, a warning is also
2609 -- generated if no entities in the package are
2610 -- referenced. This means that if the package
2611 -- is referenced but the only references are in
2612 -- use clauses or renames declarations, a warning
2613 -- is still generated. A warning is also generated
2614 -- for a generic package that is with'ed but never

2685 -- Where 'a', 'b', 'c', and 'd' are the four hexadecimal
2686 -- characters (using uppercase letters) of the wide
2687 -- character code. For example, ESC A345 is used to
2688 -- represent the wide character with code 16#A345#. This
2689 -- scheme is compatible with use of the full
2690 -- Wide_Character set.
2692 -- UPPER The wide character with encoding 16#abcd# where the
2693 -- upper bit is on (in other words, "a" is in the range
2694 -- 8-F) is represented as two bytes, 16#ab# and 16#cd#.
2695 -- The second byte may never be a format control
2696 -- character, but is not required to be in the upper
