+/* A Short Introduction to Adding a Command-Line Option.
+
+ Before adding a command-line option, consider if it is really
+ necessary. Each additional command-line option adds complexity and
+ is difficult to remove in subsequent versions.
+
+ In the following, consider adding the command-line argument
+ `--bar'.
+
+ 1. Each command-line option is specified in the specs file. The
+ notation is described below in the comment entitled "The Specs
+ Language". Read it.
+
+ 2. In this file, add an entry to "option_map" equating the long
+ `--' argument version and any shorter, single letter version. Read
+ the comments in the declaration of "struct option_map" for an
+ explanation. Do not omit the first `-'.
+
+ 3. Look in the "specs" file to determine which program or option
+ list should be given the argument, e.g., "cc1_options". Add the
+ appropriate syntax for the shorter option version to the
+ corresponding "const char *" entry in this file. Omit the first
+ `-' from the option. For example, use `-bar', rather than `--bar'.
+
+ 4. If the argument takes an argument, e.g., `--baz argument1',
+ modify either DEFAULT_SWITCH_TAKES_ARG or
+ DEFAULT_WORD_SWITCH_TAKES_ARG in this file. Omit the first `-'
+ from `--baz'.
+
+ 5. Document the option in this file's display_help(). If the
+ option is passed to a subprogram, modify its corresponding
+ function, e.g., cppinit.c:print_help() or toplev.c:display_help(),
+ instead.
+
+ 6. Compile and test. Make sure that your new specs file is being
+ read. For example, use a debugger to investigate the value of
+ "specs_file" in main(). */

+Specs are strings containing lines, each of which (if not blank)

The program name must be exact and start from root, since no path

%b substitute the basename of the input file being processed.
This is the substring up to (and not including) the last period
and not including the directory.
+ %B same as %b, but include the file suffix (text after the last period).
%gSUFFIX
substitute a file name that has suffix SUFFIX and is chosen
once per compilation, and mark the argument a la %d. To reduce

chosen file names are known. For example, `%g.s ... %g.o ... %g.s'
might turn into `ccUVUUAU.s ccXYAXZ12.o ccUVUUAU.s'. SUFFIX matches
- the regexp "[.A-Za-z]*" or the special string "%O", which is
- treated exactly as if %O had been pre-processed. Previously, %g
- was simply substituted with a file name chosen once per compilation,
- without regard to any appended suffix (which was therefore treated

was already seen.
for each `%g.s' and another for each `%U.s'. Previously, %U was
simply substituted with a file name chosen for the previous %u,

+ of a temporary file, just like %u. This temporary file is not
+ meant for communication between processes, but rather as a junk

+ substitutes .SUFFIX for the suffixes of a matched switch's args when

be linked.
%O substitutes the suffix for object files. Note that this is
- handled specially when it immediately follows %g, %u, or %U,
- because of the need for those to form complete file names. The
- handling is such that %O is treated exactly as if it had already
- been substituted, except that %g, %u, and %U do not currently

%p substitutes the standard macro predefinitions for the
current target machine. Use this when running cpp.

%x{OPTION} Accumulate an option for %X.
%X Output the accumulated linker options specified by compilations.

%| output "-" if the input for the current command is coming from a pipe.
If that switch was not specified, this substitutes nothing.
Here S is a metasyntactic variable.
%{S*} substitutes all the switches specified to CC whose names start
- with -S. This is used for -o, -D, -I, etc; switches that take
+ with -S. This is used for -o, -I, etc; switches that take
arguments. CC considers `-o foo' as being one switch whose
name starts with `o'. %{o*} would substitute this text,
including the space; thus, two arguments would be generated.
%{^S*} likewise, but don't put a blank between a switch and any args.
+ %{S*&T*} likewise, but preserve order of S and T options (the order
+ of S and T in the spec is not significant). Can be any number
+ of ampersand-separated variables; for each the wild card is
+ optional. Useful for CPP as %{D*&U*&A*}.
%{S*:X} substitutes X if one or more switches whose names start with -S are
specified to CC. Note that the tail part of the -S option
(i.e. the part matched by the `*') will be substituted for each
occurrence of %* within X.
+ %{<S} remove all occurences of -S from the command line.
+ Note - this option is position dependent. % commands in the
+ spec string before this option will see -S, % commands in the
+ spec string after this option will not.
%{S:X} substitutes X, but only if the -S switch was given to CC.
%{!S:X} substitutes X, but only if the -S switch was NOT given to CC.
%{|S:X} like %{S:X}, but if no S switch, substitute `-'.
