-- This package contains, for each of the command of the GNAT driver, one
-- constant array; each component of this array is a string that defines,
-- in coded form as explained below, the conversion of a VMS qualifier of the
-- command to the corresponding switch of the GNAT tool corresponding to the
-- command.
-- This package is used by the GNAT driver to invokes the GNAT tools with the
-- switches corresponding to the VMS qualifier and by the Project Manager to
-- convert VMS qualifiers in project files to their corresponding switch
-- values.
-- This package is also an input to the tool that generates the VMS GNAT
-- help information automatically.
-- NOTE: the format of this package must follow the following rules, so that
-- the VMS GNAT help tool works properly:
-- - Each command zone (where the eventual qualifiers are declared must
-- begin with a boxed comment of the form:
-- ---------------------------------
-- -- Switches for GNAT <COMMAND> --
-- ---------------------------------
-- where <COMMAND> is the name of a GNAT command in capital letters, for
-- example BIND, COMPILE, XREF, ...
-- - each qualifier declaration must be followed either by
-- - a comment starting with "-- NODOC", to indicate that there is
-- no documentation for this qualifier, or
-- - a contiguous sequence of comments that constitute the
-- documentation of the qualifier.
-- - each command zone ends with the declaration of the contant array
-- for the command, of the form:

-- QUALIFIERS --
----------------
-- The syntax of a qualifier delaration is as follows:
-- SWITCH_STRING ::= "/ command-qualifier-name TRANSLATION"
-- TRANSLATION ::=
-- DIRECT_TRANSLATION
-- | DIRECTORIES_TRANSLATION
-- | FILE_TRANSLATION
-- | NO_SPACE_FILE_TRANSL
-- | NUMERIC_TRANSLATION
-- | STRING_TRANSLATION
-- | OPTIONS_TRANSLATION
-- | COMMANDS_TRANSLATION
-- | ALPHANUMPLUS_TRANSLATION
-- | OTHER_TRANSLATION
-- DIRECT_TRANSLATION ::= space UNIX_SWITCHES
-- DIRECTORIES_TRANSLATION ::= =* UNIX_SWITCH *
-- DIRECTORY_TRANSLATION ::= =% UNIX_SWITCH %
-- FILE_TRANSLATION ::= =@ UNIX_SWITCH @
-- NO_SPACE_FILE_TRANSL ::= =< UNIX_SWITCH >
-- NUMERIC_TRANSLATION ::= =# UNIX_SWITCH # | # number #
-- STRING_TRANSLATION ::= =" UNIX_SWITCH "
-- OPTIONS_TRANSLATION ::= =OPTION {space OPTION}
-- COMMANDS_TRANSLATION ::= =? 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.

--
-- Specifies the main project file to be used. The project files rooted

-- /READ_SOURCES[=(keyword[,...])]
-- /NOREAD_SOURCES
--
-- The following keyword are accepted:
--
-- ALL (D) Require source files to be present. In this mode, the
-- binder insists on being able to locate all source files
-- that are referenced and checks their consistency. In
-- normal mode, if a source file cannot be located it is
-- simply ignored. If you specify the ALL keyword, a
-- missing source file is an error.
--
-- NONE Exclude source files. In this mode, the binder only
-- checks that ALI files are consistent with one another.
-- source files are not accessed. The binder runs faster
-- in this mode, and there is still a guarantee that the
-- resulting program is self-consistent.
--
-- If a source file has been edited since it was last
-- compiled and you specify the NONE keyword, the binder
-- will not detect that the object file is out of date
-- with the source file.
--
-- This is the same as specifying /NOREAD_SOURCES.
--
-- AVAILABLE Check that object files are consistent with one
-- another and are consistent with any source files that
-- can be located.
S_Bind_ReadX : aliased constant S := "/NOREAD_SOURCES " &

-- by GNAT BIND.
S_Bind_Report : aliased constant S := "/REPORT_ERRORS=" &
"VERBOSE " &
"-v " &
"BRIEF " &
"-b " &
"DEFAULT " &
"!-b,!-v";
-- /REPORT_ERRORS[=(keyword[,...])]
-- VERBOSE (D)
-- BRIEF
-- DEFAULT
-- /NOREPORT_ERRORS
--
-- With the DEFAULT keyword (which is not the default when the binder is
-- run from GNAT BIND) or the /NOREPORT_ERRORS qualifier, brief error
-- messages are generated to SYS$ERROR. If the VERBOSE keyword is
-- present, a header is written to SYS$OUTPUT and any error messages are
-- directed to SYS$OUTPUT All that is written to SYS$ERROR is a brief
-- summary message.
--
-- If the BRIEF keyword is specified, the binder will generate brief error
-- messages to SYS$ERROR even if verbose mode is specified. This is
-- relevant only when used together with the VERBOSE keyword or /VERBOSE
-- qualifier.
S_Bind_ReportX : aliased constant S := "/NOREPORT_ERRORS " &
"!-b,!-v";

S_Bind_Restr : aliased constant S := "/RESTRICTION_LIST " &
"-r";
-- /NORESTRICTION_LIST (D)

-- used to improve code generation in some cases.
S_Bind_RTS : aliased constant S := "/RUNTIME_SYSTEM=|" &
"--RTS=|";
-- /RUNTIME_SYSTEM=xxx
--
-- Binds against an alternate runtime system named xxx or RTS-xxx.
S_Bind_Search : aliased constant S := "/SEARCH=*" &
"-I*";
-- /SEARCH=(directory[,...])
--
-- When looking for source or object files also look in directories
-- specified.
--
-- This is the same as specifying both /LIBRARY_SEARCH and /SOURCE_SEARCH
-- for a directory.
S_Bind_Shared : aliased constant S := "/SHARED " &
"-shared";
-- /SHARED (D)
-- /NOSHARED
--
-- Link against a shared GNAT run time when available.
S_Bind_Slice : aliased constant S := "/TIME_SLICE=#" &
"-T#";
-- /TIME_SLICE=nnn
--
-- Set the time slice value to nnn milliseconds. A value of zero means no
-- time slicing and also indicates to the tasking run time to match as
-- close as possible to the annex D requirements of the RM.
S_Bind_Source : aliased constant S := "/SOURCE_SEARCH=*" &
"-aI*";
-- /SOURCE_SEARCH=(directory[,...])
--
-- When looking for source files also look in directories specified.
S_Bind_Store : aliased constant S := "/STORE_TRACEBACKS " &
"-E";
-- /STORE_TRACEBACKS (D)
-- /NOSTORE_TRACEBACKS
--
-- Store tracebacks in exception occurrences.
-- This is the default on VMS, with the zero-cost exception mechanism.
-- This qualifier has no impact, except when using the setjmp/longjmp
-- exception mechanism, with the GNAT COMPILE qualifier /LONGJMP_SETJMP.
S_Bind_Time : aliased constant S := "/TIME_STAMP_CHECK " &
"!-t";
-- /TIME_STAMP_CHECK (D)
--
-- Time stamp errors will be treated as errors.
--
-- /NOTIME_STAMP_CHECK
--
-- Ignore time stamp errors. Any time stamp error messages are treated as
-- warning messages. This switch essentially disconnects the normal
-- consistency checking, and the resulting program may have undefined
-- semantics if inconsistent units are present.
--
-- This means that /NOTIME_STAMP_CHECK should be used only in unusual
-- situations, with extreme care.
S_Bind_Verbose : aliased constant S := "/VERBOSE " &
"-v";
-- /VERBOSE (D)
-- /NOVERBOSE
--
-- Equivalent to /REPORT_ERRORS=VERBOSE.
S_Bind_Warn : aliased constant S := "/WARNINGS=" &
"NORMAL " &
"!-ws,!-we " &
"SUPPRESS " &
"-ws " &
"ERROR " &
"-we";
-- /WARNINGS[=(keyword[,...])]
-- /NOWARNINGS
--
-- The following keywords are supported:
--
-- NORMAL (D) Print warning messages and treat them as warning.
-- SUPPRESS Suppress all warning messages (same as /NOWARNINGS).
-- ERROR Treat any warning messages as fatal errors
S_Bind_WarnX : aliased constant S := "/NOWARNINGS " &
"-ws";
-- NODOC (see /WARNINGS)
S_Bind_Zero : aliased constant S := "/ZERO_MAIN " &
"-z";
-- /NOZERO_MAIN (D)
-- /ZERO_MAIN
--
-- Normally the binder checks that the unit name given on the command line
-- corresponds to a suitable main subprogram. When /ZERO_MAIN is used,
-- a list of ALI files can be given, and the execution of the program
-- consists of elaboration of these units in an appropriate order.

-- /NO83 (D)
-- /83
--
-- Although GNAT is primarily an Ada 95 compiler, it accepts this
-- qualifier to specify that an Ada 83 mode program is being compiled. If
-- you specify this qualifier, GNAT rejects Ada 95 extensions and applies
-- Ada 83 semantics. It is not possible to guarantee this qualifier does
-- a perfect job; for example, some subtle tests of pathological cases,
-- such as are found in ACVC tests that have been removed from the ACVC
-- suite for Ada 95, may not compile correctly. However for practical
-- purposes, using this qualifier should ensure that programs that
-- compile correctly under the /83 qualifier can be ported reasonably
-- easily to an Ada 83 compiler. This is the main use of this qualifier.
--
-- With few exceptions (most notably the need to use "<>" on
-- unconstrained generic formal parameters), it is not necessary to use
-- this qualifier switch when compiling Ada 83 programs, because, with
-- rare and obscure exceptions, Ada 95 is upwardly compatible with Ada

-- /NOCHECKS
-- /CHECKS[=(keyword[,...])]
--
-- If you compile with the default options, GNAT will insert many runtime
-- checks into the compiled code, including code that performs range
-- checking against constraints, but not arithmetic overflow checking for
-- integer operations (including division by zero) or checks for access
-- before elaboration on subprogram calls. All other runtime checks, as
-- required by the Ada 95 Reference Manual, are generated by default.
--
-- You may specify one or more of the following keywords to the /CHECKS
-- qualifier to modify this behavior:
--
-- DEFAULT The behavior described above. This is the default
-- if the /CHECKS qualifier is not present on the
-- command line. Same as /NOCHECKS.
--
-- OVERFLOW Enables overflow checking for integer operations and
-- checks for access before elaboration on subprogram
-- calls. This causes GNAT to generate slower and larger
-- executable programs by adding code to check for both
-- overflow and division by zero (resulting in raising
-- "Constraint_Error" as required by Ada semantics).
-- Similarly, GNAT does not generate elaboration check
-- by default, and you must specify this keyword to
-- enable them.
--
-- Note that this keyword does not affect the code
-- generated for any floating-point operations; it
-- applies only to integer operations. For floating-point,
-- GNAT has the "Machine_Overflows" attribute set to
-- "False" and the normal mode of operation is to generate
-- IEEE NaN and infinite values on overflow or invalid
-- operations (such as dividing 0.0 by 0.0).
--
-- ELABORATION Enables dynamic checks for access-before-elaboration
-- on subprogram calls and generic instantiations.
--
-- ASSERTIONS The pragmas "Assert" and "Debug" normally have no
-- effect and are ignored. This keyword causes "Assert"
-- and "Debug" pragmas to be activated.
--
-- SUPPRESS_ALL Suppress all runtime checks as though you have "pragma
-- Suppress (all_checks)" in your source. Use this switch
-- to improve the performance of the code at the expense
-- of safety in the presence of invalid data or program
-- bugs.
--
-- DEFAULT Suppress the effect of any option OVERFLOW or
-- ASSERTIONS.
--
-- FULL (D) Similar to OVERFLOW, but suppress the effect of any
-- option ELABORATION or SUPPRESS_ALL.
--
-- These keywords only control the default setting of the checks. You
-- may modify them using either "Suppress" (to remove checks) or
-- "Unsuppress" (to add back suppressed checks) pragmas in your program
-- source.

-- /DATA_PREPROCESSING=file_name
--
-- This qualifier indicates to the compiler the file name (without
-- directory information) of the preprocessor data file to use.
-- The preprocessor data file should be found in the source directories.
--
-- A preprocessing data file is a text file with significant lines
-- indicating how should be preprocessed either a specific source or all
-- sources not mentioned in other lines. A significant line is a non
-- empty, non comment line. Comments are similar to Ada comments.
--
-- Each significant line starts with either a literal string or the
-- character '*'. A literal string is the file name (without directory
-- information) of the source to preprocess. A character '*' indicates the
-- preprocessing for all the sources that are not specified explicitly on
-- other lines. It is an error to have two lines with the same file name
-- or two lines starting with the character '*'.
--
-- After the file name or the character '*', another optional literal
-- string indicating the file name of the definition file to be used for
-- preprocessing. (see 15.3 Form of Definitions File. The definition files
-- are found by the compiler in one of the source directories. In some
-- cases, when compiling a source in a directory other than the current
-- directory, if the definition file is in the current directory, it may
-- be necessary to add the current directory as a source directory through
-- qualifier "/SEARCH=[]", otherwise the compiler would not find the
-- definition file.
--
-- Then, optionally, switches similar to those of gnatprep may be found.
-- Those switches are:
--
-- -b Causes both preprocessor lines and the lines deleted by
-- preprocessing to be replaced by blank lines, preserving
-- the line number. This switch is always implied;
-- however, if specified after `-c' it cancels the effect
-- of `-c'.
--
-- -c Causes both preprocessor lines and the lines deleted by
-- preprocessing to be retained as comments marked with
-- the special string "--! ".
--
-- -Dsymbol=value Define or redefine a symbol, associated with value.
-- A symbol is an Ada identifier, or an Ada reserved word,
-- with the exception of "if", "else", "elsif", "end",
-- "and", "or" and "then". value is either a literal
-- string, an Ada identifier or any Ada reserved word.
-- A symbol declared with this switch replaces a symbol
-- with the same name defined in a definition file.
--
-- -s Causes a sorted list of symbol names and values to be
-- listed on the standard output file.
--
-- -u Causes undefined symbols to be treated as having the
-- value FALSE in the context of a preprocessor test.
-- In the absence of this option, an undefined symbol
-- in a #if or #elsif test will be treated as an error.
--
-- Examples of valid lines in a preprocessor data file:
--
-- "toto.adb" "prep.def" -u
-- -- preprocess "toto.adb", using definition file "prep.def",
-- -- undefined symbol are False.
--
-- * -c -DVERSION=V101
-- -- preprocess all other sources without a definition file;

-- These mappings are used by the compiler to short-circuit the path

--
-- The use of mapping files is not required for correct operation of the

-- sources are read over a slow network connection. In normal operation,
-- you need not be concerned with the format or use of mapping files,
-- and /MAPPING_FILE is not a qualifier that you would use explicitly.
-- It is intended only for use by automatic tools such as GNAT MAKE
-- running under the project file facility. The description here of the
-- format of mapping files is provided for completeness and for possible
-- use by other tools.
--
-- A mapping file is a sequence of sets of three lines. In each set, the
-- first line is the unit name, in lower case, with "%s" appended for
-- specifications and "%b" appended for bodies; the second line is the
-- file name; and the third line is the path name.
--
-- Example:
--
-- main%b
-- main.2_ada
-- /gnat/project1/sources/main.2_ada
--
-- When qualifier ?MAPPING_FILE is specified, the compiler will create in
-- memory the two mappings from the specified file. If there is any
-- problem (non existent file, truncated file or duplicate entries),
-- no mapping will be created.
--
-- Several /MAPPING_FILE qualifiers may be specified; however, only the

--
-- BRIEF Generate the brief format error messages to

--
-- IMMEDIATE Normally, the compiler saves up error messages and

-- /NOSTYLE_CHECKS (D)
-- /STYLE_CHECKS[=(keyword,[...])]
--
-- Normally, GNAT permits any code layout consistent with the reference
-- manual requirements. This qualifier imposes style checking on the
-- input source code. The following keywords are supported:
--
-- ALL_BUILTIN (D) Equivalent to the following list of options:
-- 3, ATTRIBUTE, BLANKS, COMMENTS, END, VTABS,
-- HTABS, IF_THEN, KEYWORD, LAYOUT, LINE_LENGTH,
-- PRAGMA, REFERENCES, SPECS, TOKEN.
--
-- 1 .. 9 Specify indentation level from 1 to 9.
-- The general style of required indentation is as
-- specified by the examples in the Ada Reference
-- Manual. Full line comments must be aligned with
-- the -- starting on a column that is a multiple
-- of the alignment level.
--
-- ATTRIBUTE Check attribute casing.
-- Attribute names, including the case of keywords
-- such as digits used as attributes 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.
--
-- BLANKS Blanks not allowed at statement end.
-- Trailing blanks are not allowed at the end of
-- statements. The purpose of this rule, together
-- with option HTABS (no horizontal tabs), is to
-- enforce a canonical format for the use of
-- blanks to separate source tokens.
--
-- COMMENTS Check comments.
-- Comments must meet the following set of rules:
--
-- * The "--" that starts the column must either
-- start in column one, or else at least one
-- blank must precede this sequence.
--
-- * Comments that follow other tokens on a line
-- must have at least one blank following the
-- "--" at the start of the comment.
--
-- * Full line comments must have two blanks
-- following the "--" that starts the comment,
-- with the following exceptions.
--
-- * A line consisting only of the "--"
-- characters, possibly preceded by blanks is
-- permitted.
--
-- * A comment starting with "--x" where x is
-- a special character is permitted. This
-- allows proper processing of the output
-- generated by specialized tools including
-- gnatprep (where --! is used) and the SPARK
-- annnotation language (where --# is used).
-- For the purposes of this rule, a special
-- character is defined as being in one of the
-- ASCII ranges 16#21#..16#2F# or
-- 16#3A#..16#3F#.
--
-- * A line consisting entirely of minus signs,
-- possibly preceded by blanks, is permitted.
-- This allows the construction of box
-- comments where lines of minus signs are
-- used to form the top and bottom of the box.
--
-- * If a comment starts and ends with "--" is
-- permitted as long as at least one blank
-- follows the initial "--". Together with
-- the preceding rule, this allows the
-- construction of box comments, as shown in
-- the following example:
--
--
-- ---------------------------
-- -- This is a box comment --
-- -- with two text lines. --
-- ---------------------------
--
-- 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.
--
-- 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.

--
-- Normally, GNAT allows only a single unit in a source file. However,

-- Suppress the output of all warning messages from the GNAT front end.
-- Note that it does not suppress warnings from the gcc back end.
--
-- /WARNINGS[=(keyword[,...])]
--
-- In addition to error messages, corresponding to illegalities as
-- defined in the reference manual, the compiler detects two kinds of
-- warning situations. First, the compiler considers some constructs
-- suspicious and generates a warning message to alert you to a possible
-- error. Second, if the compiler detects a situation that is sure to
-- raise an exception at runtime, it generates a warning message.
--
-- You may specify the following keywords to change this behavior:
--
-- DEFAULT (D) The default behavior above.
--
-- ALL Activate all optional warnings.
-- Activates most optional warning messages,
-- see remaining list in this section for
-- details on optional warning messages that
-- can be individually controlled.
-- The warnings that are not turned on by
-- this option are BIASED_ROUNDING,
-- IMPLICIT_DEREFERENCE, HIDING and
-- ELABORATION. 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

--
-- 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

-- /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.

-- /ACTIONS=(keyword[,...])
--
-- GNAT MAKE default behavior is to check if the sources are up to date,
-- compile those sources that are not up to date, bind the main source,
-- then link the executable.
--
-- With the /ACTIONS qualifier, GNAT MAKE may be restricted to one or
-- two of these three steps:
--
-- o Compile
-- o Bind
-- o Link
--
--
-- You may specify one or more of the following keywords to the /ACTIONS
-- qualifier:
--
-- BIND Bind only. Can be combined with /ACTIONS=COMPILE
-- to do compilation and binding, but no linking.
-- Can be combined with /ACTIONS=LINK to do binding and
-- linking. When not combined with /ACTIONS=COMPILE,
-- all the units in the closure of the main program must
-- have been previously compiled and must be up to date.
--
-- COMPILE Compile only. Do not perform binding, except when
-- /ACTIONS=BIND is also specified. Do not perform
-- linking, except if both /ACTIONS=BIND and /ACTIONS=LINK
-- are also specified.
--
-- LINK Link only. Can be combined with /ACTIONS=BIND to do
-- binding and linking. Linking will not be performed
-- if combined with /ACTIONS=COMPILE but not with
-- /ACTIONS=BIND\. When not combined with /ACTIONS=BIND
-- all the units in the closure of the main program must
-- have been previously compiled and must be up to date,
-- and the main program need to have been bound.
S_Make_All : aliased constant S := "/ALL_FILES " &
"-a";
-- /NOALL_FILES (D)
-- /ALL_FILES
--
-- Consider all files in the make process, even the GNAT internal system
-- files (for example, the predefined Ada library files). By default,
-- GNAT MAKE does not check these files (however, if there is an
-- installation problem, it will be caught when GNAT MAKE binds your
-- program). You may have to specify this qualifier if you are working on
-- GNAT itself. The vast majority of GNAT MAKE users never need to
-- specify this switch. All GNAT internal files with will be compiled
-- with /STYLE_CHECK=GNAT.
S_Make_Allproj : aliased constant S := "/ALL_PROJECTS " &
"-U";
-- /NOALL_PROJECTS (D)
-- /ALL_PROJECTS
--
-- Implies /Unique.
-- When used without project files, it is equivalent to /UNIQUE.
-- When used with a project file wit no main (neither on the command
-- line nor in the attribute Main) check every source of every project,
-- recompile all sources that are not up to date and rebuild libraries
-- if necessary.
S_Make_Bind : aliased constant S := "/BINDER_QUALIFIERS=?" &
"-bargs BIND";
-- /BINDER_QUALIFIERS
--
-- Any qualifiers specified after this qualifier other than
-- /COMPILER_QUALIFIERS, /LINKER_QUALIFIERS and /MAKE_QUALIFIERS will be
-- passed to any GNAT BIND commands generated by GNAT MAKE.
S_Make_Bindprj : aliased constant S := "/BND_LNK_FULL_PROJECT " &
"-B";
-- /BND_LNK_FULL_PROJECT
--
-- Bind and link all sources of a project, without any consideration
-- to attribute Main, if there is one. This qualifier need to be
-- used in conjunction with the /PROJECT_FILE= qualifier and cannot
-- be used with a main subprogram on the command line or for
-- a library project file. As the binder is invoked with the option
-- meaning "No Ada main subprogram", the user must ensure that the
-- proper options are specified to the linker. This qualifier is
-- normally used when the main subprogram is in a foreign language
-- such as C.
S_Make_Comp : aliased constant S := "/COMPILER_QUALIFIERS=?" &
"-cargs COMPILE";
-- /COMPILER_QUALIFIERS
--
-- Any qualifiers specified after this qualifier other than
-- /BINDER_QUALIFIERS, /LINKER_QUALIFIERS and /MAKE_QUALIFIERS will be
-- passed to any GNAT COMPILE commands generated by GNAT MAKE.
S_Make_Cond : aliased constant S := "/CONDITIONAL_SOURCE_SEARCH=*" &

-- /CONDITIONAL_SOURCE_SEARCH=dir
--
-- Equivalent to "/SOURCE_SEARCH=dir /SKIP_MISSING=dir".
S_Make_Cont : aliased constant S := "/CONTINUE_ON_ERROR " &
"-k";
-- /NOCONTINUE_ON_ERROR (D)
-- /CONTINUE_ON_ERROR
--
-- Keep going. Continue as much as possible after a compilation error.
-- To ease the programmer's task in case of compilation errors, the list
-- of sources for which the compile fails is given when GNAT MAKE
-- terminates.
S_Make_Current : aliased constant S := "/CURRENT_DIRECTORY " &
"!-I-";
-- /CURRENT_DIRECTORY (D)
-- /NOCURRENT_DIRECTORY
--
-- Look for source, library or object files in the default directory.
S_Make_Dep : aliased constant S := "/DEPENDENCIES_LIST " &
"-M";
-- /NODEPENDENCIES_LIST (D)
-- /DEPENDENCIES_LIST
--
-- Check if all objects are up to date. If they are, output the object
-- dependences to SYS$OUTPUT in a form that can be directly exploited in
-- a Unix-style Makefile. By default, each source file is prefixed with
-- its (relative or absolute) directory name. This name is whatever you
-- specified in the various /SOURCE_SEARCH and /SEARCH qualifiers. If
-- you also speficy the /QUIET qualifier, only the source file names,
-- without relative paths, are output. If you just specify the
-- /DEPENDENCY_LIST qualifier, dependencies of the GNAT internal system
-- files are omitted. This is typically what you want. If you also
-- specify the /ALL_FILES qualifier, dependencies of the GNAT internal
-- files are also listed. Note that dependencies of the objects in
-- external Ada libraries (see the /SKIP_MISSING qualifier) are never
-- reported.
S_Make_Dirobj : aliased constant S := "/DIRECTORY_OBJECTS=@" &
"-D@";
-- /DIRECTORY_OBJECTS=<file>
--
-- Put all object files and .ALI files in <file>.
-- This qualifier is not compatible with /PROJECT_FILE.
S_Make_Doobj : aliased constant S := "/DO_OBJECT_CHECK " &
"-n";
-- /NODO_OBJECT_CHECK (D)
-- /DO_OBJECT_CHECK
--
-- Don't compile, bind, or link. Output a single command that will
-- recompile an out of date unit, if any. Repeated use of this option,
-- followed by carrying out the indicated compilation, will eventually
-- result in recompiling all required units.
--
-- If any ALI is missing during the process, GNAT MAKE halts and
-- displays an error message.
S_Make_Execut : aliased constant S := "/EXECUTABLE=@" &
"-o@";
-- /EXECUTABLE=exec-name
--
-- The name of the final executable program will be 'exec_name'. If this
-- qualifier is omitted the default name for the executable will be the
-- name of the input file with an EXE filetype. You may prefix
-- 'exec_name' with a relative or absolute directory path.
S_Make_Ext : aliased constant S := "/EXTERNAL_REFERENCE=" & '"' &
"-X" & '"';
-- /EXTERNAL_REFERENCE="name=val"
--
-- Specifies an external reference to the project manager. Useful only if

--
-- Example:
-- /EXTERNAL_REFERENCE="DEBUG=TRUE"
S_Make_Force : aliased constant S := "/FORCE_COMPILE " &
"-f";
-- /NOFORCE_COMPILE (D)
-- /FORCE_COMPILE
--
-- Force recompilations. Recompile all sources, even though some object

-- internal files unless the /ALL_FILES qualfier is also specified.
S_Make_Full : aliased constant S := "/FULL_PATH_IN_BRIEF_MESSAGES " &
"-F";
-- /NOFULL_PATH_IN_BRIEF_MESSAGES (D)
-- /FULL_PATH_IN_BRIEF_MESSAGES
--
-- When using project files, if some errors or warnings are detected
-- during parsing and verbose mode is not in effect (no use of qualifier
-- /VERBOSE), then error lines start with the full path name of the
-- project file, rather than its simple file name.
S_Make_Inplace : aliased constant S := "/IN_PLACE " &
"-i";
-- /NOIN_PLACE (D)
-- /IN_PLACE
--
-- In normal mode, GNAT MAKE compiles all object files and ALI files
-- into the current directory. If the /IN_PLACE switch is used,
-- then instead object files and ALI files that already exist are over-
-- written in place. This means that once a large project is organized
-- into separate directories in the desired manner, then GNAT MAKE will
-- automatically maintain and update this organization. If no ALI files
-- are found on the Ada object path, the new object and ALI files are
-- created in the directory containing the source being compiled.
S_Make_Library : aliased constant S := "/LIBRARY_SEARCH=*" &
"-L*";
-- /LIBRARY_SEARCH=(directory[,...])
--
-- Add the specified directories to the list of directories in which the
-- linker will search for libraries.
S_Make_Link : aliased constant S := "/LINKER_QUALIFIERS=?" &
"-largs LINK";
-- /LINKER_QUALIFIERS
--
-- Any qualifiers specified after this qualifier other than
-- /COMPILER_QUALIFIERS, /BINDER_QUALIFIERS and /MAKE_QUALIFIERS will be
-- passed to any GNAT LINK commands generated by GNAT LINK.
S_Make_Make : aliased constant S := "/MAKE_QUALIFIERS=?" &
"-margs MAKE";
-- /MAKE_QUALIFIERS
--
-- Any qualifiers specified after this qualifier other than
-- /COMPILER_QUALIFIERS, /BINDER_QUALIFIERS and /LINKER_QUALIFIERS
-- are for the benefit of GNAT MAKE itself.
S_Make_Mapping : aliased constant S := "/MAPPING " &
"-C";
-- /NOMAPPING (D)
-- /MAPPING
--
-- Use a mapping file. A mapping file is a way to communicate to the
-- compiler two mappings: from unit names to file names (without any
-- directory information) and from file names to path names (with full
-- directory information). These mappings are used by the compiler to
-- short-circuit the path search. When GNAT MAKE is invoked with this
-- qualifier, it will create a mapping file, initially populated by the
-- project manager, if /PROJECT_File= is used, otherwise initially empty.
-- Each invocation of the compiler will add the newly accessed sources to
-- the mapping file. This will improve the source search during the next
-- invocations of the compiler
S_Make_Mess : aliased constant S := "/MESSAGES_PROJECT_FILE=" &
"DEFAULT " &
"-vP0 " &
"MEDIUM " &
"-vP1 " &
"HIGH " &

-- /MESSAGES_PROJECT_FILE[=messages-option]

S_Make_Minimal : aliased constant S := "/MINIMAL_RECOMPILATION " &
"-m";
-- /NOMINIMAL_RECOMPILATION (D)
-- /MINIMAL_RECOMPILATION
--
-- Specifies that the minimum necessary amount of recompilation
-- be performed. In this mode GNAT MAKE ignores time stamp differences
-- when the only modifications to a source file consist in
-- adding/removing comments, empty lines, spaces or tabs.
S_Make_Nolink : aliased constant S := "/NOLINK " &
"-c";
-- /NOLINK
--
-- Compile only. Do not perform binding and linking. If the root unit is
-- not a main unit, this is the default. Otherwise GNAT MAKE will
-- attempt binding and linking unless all objects are up to date and the
-- executable is more recent than the objects.
-- This is equivalent to /ACTIONS=COMPILE
S_Make_Nomain : aliased constant S := "/NOMAIN " &
"-z";
-- /NOMAIN
--
-- No main subprogram. Bind and link the program even if the unit name
-- given on the command line is a package name. The resulting executable
-- will execute the elaboration routines of the package and its closure,
-- then the finalization routines.
S_Make_Nostinc : aliased constant S := "/NOSTD_INCLUDES " &
"-nostdinc";
-- /NOSTD_INCLUDES
--
-- Do not look for sources the in the system default directory.
S_Make_Nostlib : aliased constant S := "/NOSTD_LIBRARIES " &

-- When looking for library and object files look also in the specified
-- directories.
S_Make_Proc : aliased constant S := "/PROCESSES=#" &
"-j#";
-- /NOPROCESSES (D)
-- /PROCESSES=NNN
--
-- Use NNN processes to carry out the (re)complations. If you have a
-- multiprocessor machine, compilations will occur in parallel. In the
-- event of compilation errors, messages from various compilations might
-- get interspersed (but GNAT MAKE will give you the full ordered list of
-- failing compiles at the end). This can at times be annoying. To get a
-- clean list of error messages don't use this qualifier.
S_Make_Nojobs : aliased constant S := "/NOPROCESSES " &
"-j1";
-- NODOC (see /PROCESS)
S_Make_Project : aliased constant S := "/PROJECT_FILE=<" &
"-P>";
-- /PROJECT_FILE=filename
--
-- Specifies the main project file to be used. The project files rooted
-- at the main project file will be parsed before any other processing to
-- set the building environment.
S_Make_Quiet : aliased constant S := "/QUIET " &
"-q";

--
-- Search the specified directories for both source and object files.
S_Make_Skip : aliased constant S := "/SKIP_MISSING=*" &

--
-- Skip missing library sources if ALI in 'directory'.
S_Make_Source : aliased constant S := "/SOURCE_SEARCH=*" &

-- /SOURCE_SEARCH=(directory[,...])
--
-- When looking for source files also look in the specified directories.
S_Make_Switch : aliased constant S := "/SWITCH_CHECK " &
"-s";
-- /NOSWITCH_CHECK (D)
-- /SWITCH_CHECK
--
-- Recompile if compiler switches have changed since last compilation.
-- All compiler switches but -I and -o are taken into account in the
-- following way: orders between different "first letter" switches are
-- ignored, but orders between same switches are taken into account.
-- For example, -O -O2 is different than -O2 -O, but -g -O is equivalent
-- to -O -g.
S_Make_Unique : aliased constant S := "/UNIQUE " &
"-u";
-- /NOUNIQUE (D)
-- /UNIQUE
--
-- Recompile at most the main file. It implies /ACTIONS=COMPILE.
-- Combined with /FORCE_COMPILE, it is equivalent to calling the compiler
-- directly.
S_Make_Use_Map : aliased constant S := "/USE_MAPPING_File=@" &
"-C=@";
-- /USE_MAPPING_FILE=file_name
--
-- Use a specific mapping file. The file 'file_name', specified as a path

-- otherwise the qualifier is ineffective. The specified mapping file
-- will be communicated to the compiler. This switch is not compatible
