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'. - - S_Bind_Build : aliased constant S := "/BUILD_LIBRARY=|" & - "-L|"; - -- /BUILD_LIBRARY=xxx - -- - -- Binds the units for library building.

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. This warning can also be turned on - -- using /INLINE=FULL. - -- - -- NOINEFFECTIVE_INLINE Suppress warnings on ineffective pragma Inlines - -- Suppresses warnings on ineffective pragma - -- Inlines. 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. - - S_GCC_WarnX : aliased constant S := "/NOWARNINGS " & - "-gnatws"; - -- NODOC (see /WARNINGS) - - S_GCC_No_Back : aliased constant S := "/NO_BACK_END_WARNINGS " & - "-w"; - -- /NO_BACK_END_WARNINGS - -- - -- Inhibit all warning messages of the GCC back-end. - - S_GCC_Wide : aliased constant S := "/WIDE_CHARACTER_ENCODING=" & - "BRACKETS " & - "-gnatWb " & - "NONE " & - "-gnatWn " & - "HEX " & - "-gnatWh " & - "UPPER " & - "-gnatWu " & - "SHIFT_JIS " & - "-gnatWs " & - "UTF8 " & - "-gnatW8 " & - "EUC " & - "-gnatWe"; - -- /NOWIDE_CHARACTER_ENCODING (D) - -- /WIDE_CHARACTER_ENCODING[=encode-type] - -- - -- Specifies the mechanism used to encode wide characters. 'encode-type' - -- is one of the following: - -- - -- BRACKETS (D) A wide character is encoded as ["xxxx"] where XXXX - -- are four hexadecimal digits representing the coding - -- ('Pos value) of the character in type - -- Wide_Character. The hexadecimal digits may use upper - -- or lower case letters. - -- - -- This notation can also be used for upper half - -- Character values using the format ["xx"] where XX is - -- two hexadecimal digits representing the coding ('Pos - -- value) of the character in type Character (or - -- Wide_Character). 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. Only characters defined in the - -- JIS code set table can be used with this encoding - -- method. - -- - -- UTF8 A wide character is represented using - -- UCS Transformation Format 8 (UTF-8) as defined in Annex - -- R of ISO 10646-1/Am.2. Depending on the character - -- value, the representation is a one, two, or three byte - -- sequence: - -- - -- 16#0000#-16#007f#: 2#0xxxxxxx# - -- 16#0080#-16#07ff#: 2#110xxxxx# 2#10xxxxxx# - -- 16#0800#-16#ffff#: 2#1110xxxx# 2#10xxxxxx# 2#10xxxxxx# - -- - -- where the xxx bits correspond to the left-padded bits - -- of the the 16-bit character value. 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. The internal character code is the - -- corresponding JIS character according to the EUC - -- encoding algorithm. Only characters defined in the JIS - -- code set table can be used with this encoding method. - - S_GCC_WideX : aliased constant S := "/NOWIDE_CHARACTER_ENCODING " & - "-gnatWn"; - -- NODOC (see /WIDE_CHARACTER_ENCODING) - - S_GCC_Xdebug : aliased constant S := "/XDEBUG " & - "-gnatD"; - -- /NOXDEBUG (D) - -- /XDEBUG - -- - -- Output expanded source files for source level debugging. - -- The expanded source (see /EXPAND_SOURCE) is written to files - -- with names formed by appending "_DG" to the input file name, - -- The debugging information generated by the /DEBUG qualifier will then - -- refer to the generated file.
