ARGS space command-name -- ALPHANUMPLUS_TRANSLATION ::= =| UNIX_SWITCH | -- UNIX_SWITCHES ::= UNIX_SWITCH {, UNIX_SWITCH} -- UNIX_SWITCH ::= unix-switch-string | !unix-switch-string | `string' -- OPTION ::= option-name space UNIX_SWITCHES -- ARGS ::= -cargs | -bargs | -largs -- Here command-qual is the name of the switch recognized by the GNATCmd. -- This is always given in upper case in the templates, although in the -- actual commands, either upper or lower case is allowed. -- The unix-switch-string always starts with a minus, and has no commas -- or spaces in it. Case is significant in the unix switch string. If a -- unix switch string is preceded by the not sign (!) it means that the -- effect of the corresponding command qualifer is to remove any previous -- occurrence of the given switch in the command line. -- The DIRECTORIES_TRANSLATION format is used where a list of directories -- is given. This possible corresponding formats recognized by GNATCmd are -- as shown by the following example for the case of PATH -- PATH=direc -- PATH=(direc,direc,direc,direc) -- When more than one directory is present for the DIRECTORIES case, then -- multiple instances of the corresponding unix switch are generated, -- with the file name being substituted for the occurrence of *. -- The FILE_TRANSLATION format is similar except that only a single -- file is allowed, not a list of files, and only one unix switch is -- generated as a result. -- the NO_SPACE_FILE_TRANSL is similar to FILE_TRANSLATION, except that -- no space is inserted between the switch and the file name. -- The NUMERIC_TRANSLATION format is similar to the FILE_TRANSLATION case -- except that the parameter is a decimal integer in the range 0 to 999. -- For the OPTIONS_TRANSLATION case, GNATCmd similarly permits one or -- more options to appear (although only in some cases does the use of -- multiple options make logical sense). For example, taking the -- case of ERRORS for GCC, the following are all allowed: -- /ERRORS=BRIEF -- /ERRORS=(FULL,VERBOSE) -- /ERRORS=(BRIEF IMMEDIATE) -- If no option is provided (e.g. just /ERRORS is written), then the -- first option in the list is the default option. For /ERRORS this -- is NORMAL, so /ERRORS with no option is equivalent to /ERRORS=NORMAL. -- The COMMANDS_TRANSLATION case is only used for gnatmake, to correspond -- to the use of -cargs, -bargs and -largs (the ARGS string as indicated -- is one of these three possibilities). The name given by COMMAND is the -- corresponding command name to be used to interprete the switches to be -- passed on. Switches of this type set modes, e.g. /COMPILER_QUALIFIERS -- sets the mode so that all subsequent switches, up to another switch -- with COMMANDS_TRANSLATION apply to the corresponding commands issued -- by the make utility. For example -- /COMPILER_QUALIFIERS /LIST /BINDER_QUALIFIERS /MAIN -- /COMPILER_QUALIFIERS /NOLIST /COMPILE_CHECKS=SYNTAX -- Clearly these switches must come at the end of the list of switches -- since all subsequent switches apply to an issued command. -- For the DIRECT_TRANSLATION case, an implicit additional qualifier -- declaration is created by prepending NO to the name of the qualifer, -- and then inverting the sense of the UNIX_SWITCHES string. For example, -- given the qualifier definition: -- "/LIST -gnatl" -- An implicit qualifier definition is created: -- "/NOLIST !-gnatl" -- In the case where, a ! is already present, inverting the sense of the -- switch means removing it. subtype S is String; -- A synonym to shorten the table type String_Ptr is access constant String; -- String pointer type used throughout type Switches is array (Natural range <>) of String_Ptr; -- Type used for array of swtiches type Switches_Ptr is access constant Switches; ---------------------------- -- Switches for GNAT BIND -- ---------------------------- S_Bind_Bind : aliased constant S := "/BIND_FILE=" & "ADA " & "-A " & "C " & "-C"; -- /BIND_FILE[=bind-file-option] -- -- Specifies the language of the binder generated file. -- -- ADA (D) Binder file is Ada. -- -- C Binder file is 'C'.

Together with -- the preceding rule, this allows the -- construction of box comments, as shown in -- the following example: -- -- --------------------------- -- -- This is a box comment -- -- --------------------------- -- -- END Check end/exit labels. -- Optional labels on end statements ending -- subprograms and on exit statements exiting -- named loops, are required to be present. -- -- GNAT Enforces a set of style conventions that -- correspond to the style used in the GNAT -- source code. All compiler units are always -- compile with this keyword specified. -- -- You can find the full documentation for the -- style conventions imposed by this keyword -- in the body of the package "Style" in the -- compiler sources. -- -- You should not normally use this keyword. -- However, you MUST use it for compiling any -- language-defined unit, or for adding children -- to any language-defined unit other than -- "Standard". -- -- HTABS No horizontal tabs. -- Horizontal tab characters are not permitted in -- the source text. Together with the BLANKS -- (no blanks at end of line) option, this -- enforces a canonical form for the use of blanks -- to separate source tokens. -- -- IF_THEN Check if-then layout. -- The keyword then must appear either on the -- same line as the corresponding if, or on a line -- on its own, lined up under the if with at least -- one non-blank line in between containing all or -- part of the condition to be tested. -- -- KEYWORD Check keyword casing. -- All keywords must be in lower case (with the -- exception of keywords such as digits used as -- attribute names to which this check does not -- apply). -- -- LAYOUT Check layout. -- Layout of statement and declaration constructs -- must follow the recommendations in the Ada -- Reference Manual, as indicated by the form of -- the syntax rules. For example an else keyword -- must be lined up with the corresponding if -- keyword. -- -- There are two respects in which the style rule -- enforced by this check option are more liberal -- than those in the Ada Reference Manual. -- First in the case of record declarations, -- it is permissible to put the record keyword on -- the same line as the type keyword, and then -- the end in end record must line up under type. -- For example, either of the following two -- layouts is acceptable: -- -- type q is record -- a : integer; -- b : integer; -- end record; -- -- type q is -- record -- a : integer; -- b : integer; -- end record; -- -- Second, in the case of a block statement, -- a permitted alternative is to put the block -- label on the same line as the declare or begin -- keyword, and then line the end keyword up under -- the block label. For example both the following -- are permitted: -- -- -- -- Block : declare -- A : Integer := 3; -- begin -- Proc (A, A); -- end Block; -- -- Block : -- declare -- A : Integer := 3; -- begin -- Proc (A, A); -- end Block; -- -- The same alternative format is allowed for -- loops. For example, both of the following are -- permitted: -- -- -- -- Clear : while J < 10 loop -- A (J) := 0; -- end loop Clear; -- -- Clear : -- while J < 10 loop -- A (J) := 0; -- end loop Clear; -- -- -- -- LINE_LENGTH Check maximum line length. -- The length of source lines must not exceed 79 -- characters, including any trailing blanks -- The value of 79 allows convenient display on -- an 80 character wide device or window, allowing -- for possible special treatment of 80 character -- lines. -- -- NONE Clear any previously set style checks. -- -- ORDERED_SUBPROGRAMS Check order of subprogram bodies. -- All subprogram bodies in a given scope (e.g. -- a package body) must be in alphabetical order. -- The ordering rule uses normal Ada rules for -- comparing strings, ignoring casing of letters, -- except that if there is a trailing numeric -- suffix, then the value of this suffix is used -- in the ordering (e.g. Junk2 comes before -- Junk10). -- -- NONE The default behavior. Same as /NOSTYLE_CHECKS. -- -- PRAGMA Check pragma casing. -- Pragma names must be written in mixed case, -- that is, the initial letter and any letter -- following an underscore must be uppercase. -- All other letters must be lowercase. -- -- REFERENCES Check references. -- All identifier references must be cased in the -- same way as the corresponding declaration. -- No specific casing style is imposed on -- identifiers. The only requirement is for -- consistency of references with declarations. -- -- RM_COLUMN_LAYOUT Enforce the layout conventions suggested by -- the examples and syntax rules of the Ada -- Language Reference Manual. For example, an -- "else" must line up with an "if" and code in -- the "then" and "else" parts must be indented. -- The compiler considers violations of the -- layout rules a syntax error if you specify -- this keyword. -- -- SPECS Check separate specs. -- Separate declarations ("specs") are required -- for subprograms (a body is not allowed to serve -- as its own declaration). The only exception is -- that parameterless library level procedures are -- not required to have a separate declaration. -- This exception covers the most frequent form of -- main program procedures. -- -- STANDARD_CASING Check casing of entities in Standard. -- Any identifier from Standard must be cased to -- match the presentation in the Ada Reference -- Manual (for example, Integer and ASCII.NUL). -- -- TOKEN Check token spacing. -- The following token spacing rules are enforced: -- -- * The keywords abs and not must be followed -- by a space. -- -- * The token => must be surrounded by spaces. -- -- * The token <> must be preceded by a space or -- a left parenthesis. -- -- * Binary operators other than ** must be -- surrounded by spaces. There is no -- restriction on the layout of the ** binary -- operator. -- -- * Colon must be surrounded by spaces. -- -- * Colon-equal (assignment) must be surrounded -- by spaces. -- -- * Comma must be the first non-blank character -- on the line, or be immediately preceded by -- a non-blank character, and must be followed -- by a space. -- -- * If the token preceding a left paren ends -- with a letter or digit, then a space must -- separate the two tokens. -- -- * A right parenthesis must either be the -- first non-blank character on a line, or it -- must be preceded by a non-blank character. -- -- * A semicolon must not be preceded by -- a space, and must not be followed by -- a non-blank character. -- -- * A unary plus or minus may not be followed -- by a space. -- -- * A vertical bar must be surrounded by -- spaces. -- -- In the above rules, appearing in column one is -- always permitted, that is, counts as meeting -- either a requirement for a required preceding -- space, or as meeting a requirement for no -- preceding space. -- -- Appearing at the end of a line is also always -- permitted, that is, counts as meeting either -- a requirement for a following space, -- or as meeting a requirement for no following -- space. -- -- VTABS No form feeds or vertical tabs. -- Form feeds or vertical tab characters are not -- permitted in the source text.

All other optional Ada -- warnings are turned on. -- -- NOALL Suppress all optional errors. -- Suppresses all optional warning messages -- that can be activated by option ALL. -- -- ALL_GCC Request additional messages from the GCC -- backend. Most of these are not relevant -- to Ada. -- -- CONDITIONALS Activate warnings for conditional -- Expressions used in tests that are known -- to be True or False at compile time. The -- default is that such warnings are not -- generated. -- -- NOCONDITIONALS Suppress warnings for conditional -- expressions used in tests that are known -- to be True or False at compile time. -- -- IMPLICIT_DEREFERENCE Activate warnings on implicit dereferencing. -- The use of a prefix of an access type in an -- indexed component, slice, or selected component -- without an explicit .all will generate -- a warning. With this warning enabled, access -- checks occur only at points where an explicit -- .all appears in the source code (assuming no -- warnings are generated as a result of this -- option). The default is that such warnings are -- not generated. Note that /WARNINGS=ALL does not -- affect the setting of this warning option. -- -- NOIMPLICIT_DEREFERENCE Suppress warnings on implicit dereferencing. -- in indexed components, slices, and selected -- components. -- -- ELABORATION Activate warnings on missing pragma -- Elaborate_All statements. The default is -- that such warnings are not generated. -- -- NOELABORATION Suppress warnings on missing pragma -- Elaborate_All statements. -- -- ERRORS Warning messages are to be treated as errors. -- The warning string still appears, but the -- warning messages are counted as errors, and -- prevent the generation of an object file. -- -- HIDING Activate warnings on hiding declarations. -- A declaration is considered hiding if it is -- for a non-overloadable entity, and it declares -- an entity with the same name as some other -- entity that is directly or use-visible. The -- default is that such warnings are not -- generated. -- -- NOHIDING Suppress warnings on hiding declarations. -- -- IMPLEMENTATION Activate warnings for a with of an internal -- GNAT implementation unit, defined as any unit -- from the Ada, Interfaces, GNAT, DEC or -- System hierarchies that is not documented in -- either the Ada Reference Manual or the GNAT -- Programmer's Reference Manual. Such units are -- intended only for internal implementation -- purposes and should not be with'ed by user -- programs. The default is that such warnings -- are generated. -- -- NOIMPLEMENTATION Disables warnings for a with of an internal -- GNAT implementation unit. -- -- INEFFECTIVE_INLINE Activate warnings on ineffective pragma Inlines -- Activates warnings for failure of front end -- inlining (activated by /INLINE=FULL) to inline -- a particular call. There are many reasons for -- not being able to inline a call, including most -- commonly that the call is too complex to -- inline.

If the inlining mechanism cannot -- inline a call, it will simply ignore the -- request silently. -- -- MODIFIED_UNREF Activates warnings for variables that are -- assigned (using an initialization value or with -- one or more assignment statements) but whose -- value is never read. The warning is suppressed -- for volatile variables and also for variables -- that are renamings of other variables or for -- which an address clause is given. This warning -- can also be turned on using /WARNINGS/OPTIONAL. -- -- NOMODIFIED_UNREF Disables warnings for variables that are -- assigned or initialized, but never read. -- -- NORMAL Sets normal warning mode, in which enabled -- warnings are issued and treated as warnings -- rather than errors. This is the default mode. -- It can be used to cancel the effect of an -- explicit /WARNINGS=SUPPRESS or -- /WARNINGS=ERRORS. It also cancels the effect -- of the implicit /WARNINGS=ERRORS that is -- activated by the use of /STYLE=GNAT. -- -- OBSOLESCENT Activates warnings for calls to subprograms -- marked with pragma Obsolescent and for use of -- features in Annex J of the Ada Reference -- Manual. In the case of Annex J, not all -- features are flagged. In particular use of the -- renamed packages (like Text_IO), use of package -- ASCII and use of the attribute 'Constrained are -- not flagged, since these are very common and -- would generate many annoying positive warnings. -- The default is that such warnings are not -- generated. -- -- NOOBSOLESCENT Disables warnings on use of obsolescent -- features. -- -- OPTIONAL Activate all optional warning messages. -- See other options under this qualifier -- for details on optional warning messages -- that can be individually controlled. The -- one exception is that /WARNINGS=OPTIONAL -- doesn't activate warnings for hiding -- variables (/WARNINGS=HIDING), so if this -- warning is required it must be explicitly -- set. -- -- NOOPTIONAL Suppress all optional warning messages. -- See other options under this qualifier -- for details on optional warning messages -- that can be individually controlled. -- -- OVERLAYS Activate warnings for possibly unintended -- initialization effects of defining address -- clauses that cause one variable to overlap -- another. The default is that such warnings -- are generated. -- -- NOOVERLAYS Suppress warnings on possibly unintended -- initialization effects of defining address -- clauses that cause one variable to overlap -- another. -- -- REDUNDANT Activate warnings for redundant constructs. -- In particular assignments of a variable to -- itself, and a type conversion that converts -- an object to its own type. The default -- is that such warnings are not generated. -- -- NOREDUNDANT Suppress warnings for redundant constructs. -- -- SUPPRESS Completely suppresse the output of all warning -- messages. Same as /NOWARNINGS. -- -- UNCHECKED_CONVERSIONS Activates warnings on unchecked conversions. -- Causes warnings to be generated for -- unchecked conversions when the two types are -- known at compile time to have different sizes. -- The default is that such warnings are -- generated. -- -- NOUNCHECKED_CONVERSIONS Suppress warnings for unchecked conversions. -- -- UNINITIALIZED Generate warnings for uninitialized variables. -- This is a GCC option, not an Ada option. -- You must also specify the /OPTIMIZE qualifier -- with a value other than NONE (in other words, -- this keyword works only if optimization is -- turned on). -- -- UNREFERENCED_FORMALS Activate warnings on unreferenced formals. -- Causes a warning to be generated if a formal -- parameter is not referenced in the body of -- the subprogram. This warning can also be turned -- on using option ALL or UNUSED. -- -- NOUNREFERENCED_FORMALS Suppress warnings on unreferenced formals. -- Suppresses warnings for unreferenced formal -- parameters. Note that the combination UNUSED -- followed by NOUNREFERENCED_FORMALS has the -- effect of warning on unreferenced entities -- other than subprogram formals. -- -- UNUSED Activates warnings to be generated for entities -- that are defined but not referenced, and for -- units that are with'ed and not referenced. In -- the case of packages, a warning is also -- generated if no entities in the package are -- referenced. This means that if the package -- is referenced but the only references are in -- use clauses or renames declarations, a warning -- is still generated. A warning is also generated -- for a generic package that is with'ed but never -- instantiated. In the case where a package or -- subprogram body is compiled, and there is a -- with on the corresponding spec that is only -- referenced in the body, a warning is also -- generated, noting that the with can be moved -- to the body. The default is that such warnings -- are not generated. -- -- NOUNUSED Suppress warnings for unused entities and -- packages. -- -- VARIABLES_UNINITIALIZED Activates warnings on unassigned variables. -- Causes warnings to be generated when a variable -- is accessed which may not be properly -- uninitialized. -- The default is that such warnings are -- generated. -- -- NOVARIABLES_UNINITIALIZED Suppress warnings for uninitialized -- variables.

The hexadecimal digits may use upper -- of lower case. -- -- NONE No wide characters are allowed. Same -- as /NOWIDE_CHARCTER_ENCODING. -- -- HEX In this encoding, a wide character is represented by -- the following five character sequence: ESC a b c d -- Where 'a', 'b', 'c', and 'd' are the four hexadecimal -- characters (using uppercase letters) of the wide -- character code. For example, ESC A345 is used to -- represent the wide character with code 16#A345#. This -- scheme is compatible with use of the full -- Wide_Character set. -- -- UPPER The wide character with encoding 16#abcd# where the -- upper bit is on (in other words, "a" is in the range -- 8-F) is represented as two bytes, 16#ab# and 16#cd#. -- The second byte may never be a format control -- character, but is not required to be in the upper -- half. This method can be also used for shift-JIS or -- EUC, where the internal coding matches the external -- coding. -- -- SHIFT_JIS A wide character is represented by a two-character -- sequence, 16#ab# and 16#cd#, with the restrictions -- described for upper-half encoding as described above. -- The internal character code is the corresponding JIS -- character according to the standard algorithm for -- Shift-JIS conversion.

Note that all lower -- half ASCII characters are represented as ASCII bytes -- and all upper half characters and other wide characters -- are represented as sequences of upper-half (The full -- UTF-8 scheme allows for encoding 31-bit characters as -- 6-byte sequences, but in this implementation, all UTF-8 -- sequences of four or more bytes length will be treated -- as illegal). -- -- EUC A wide character is represented by a two-character -- sequence 16#ab# and 16#cd#, with both characters being -- in the upper half.
