+ /* This file contains a filter for the main `gcc' driver, which is
+ replicated for the `gfortran' driver by adding this filter. The purpose
+ of this filter is to be basically identical to gcc (in that
+ it faithfully passes all of the original arguments to gcc) but,
+ unless explicitly overridden by the user in certain ways, ensure
+ that the needs of the language supported by this wrapper are met.
+
+ For GNU Fortran 95(gfortran), we do the following to the argument list
+ before passing it to `gcc':
+
+ 1. Make sure `-lgfortran -lm' is at the end of the list.
+
+ 2. Make sure each time `-lgfortran' or `-lm' is seen, it forms
+ part of the series `-lgfortran -lm'.
+
+ #1 and #2 are not done if `-nostdlib' or any option that disables
+ the linking phase is present, or if `-xfoo' is in effect. Note that
+ a lack of source files or -l options disables linking.
+
+ This program was originally made out of gcc/cp/g++spec.cc, but the
+ way it builds the new argument list was rewritten so it is much
+ easier to maintain, improve the way it decides to add or not add
+ extra arguments, etc. And several improvements were made in the
+ handling of arguments, primarily to make it more consistent with
+ `gcc' itself. */

+ \f
+ /* The Specs Language
+
+ Specs are strings containing lines, each of which (if not blank)
+ is made up of a program name, and arguments separated by spaces.
+ The program name must be exact and start from root, since no path
+ is searched and it is unreliable to depend on the current working directory.
+ Redirection of input or output is not supported; the subprograms must
+ accept filenames saying what files to read and write.
+
+ In addition, the specs can contain %-sequences to substitute variable text
+ or for conditional text. Here is a table of all defined %-sequences.
+ Note that spaces are not generated automatically around the results of
+ expanding these sequences; therefore, you can concatenate them together
+ or with constant text in a single argument.
+
+ %% substitute one % into the program name or argument.
+ %" substitute an empty argument.
+ %i substitute the name of the input file being processed.
+ %b substitute the basename for outputs related with the input file
+ being processed. This is often a substring of the input file name,
+ up to (and not including) the last period but, unless %w is active,
+ it is affected by the directory selected by -save-temps=*, by
+ -dumpdir, and, in case of multiple compilations, even by -dumpbase
+ and -dumpbase-ext and, in case of linking, by the linker output
+ name. When %w is active, it derives the main output name only from
+ the input file base name; when it is not, it names aux/dump output
+ file.
+ %B same as %b, but include the input 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
+ exposure to denial-of-service attacks, the file name is now
+ chosen in a way that is hard to predict even when previously
+ 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 "[.0-9A-Za-z]*%O"; "%O" is treated exactly as if it
+ 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 just like
+ ordinary text), making such attacks more likely to succeed.
+ %|SUFFIX
+ like %g, but if -pipe is in effect, expands simply to "-".
+ %mSUFFIX
+ like %g, but if -pipe is in effect, expands to nothing. (We have both
+ %| and %m to accommodate differences between system assemblers; see
+ the AS_NEEDS_DASH_FOR_PIPED_INPUT target macro.)
+ %uSUFFIX
+ like %g, but generates a new temporary file name even if %uSUFFIX
+ was already seen.
+ %USUFFIX
+ substitutes the last file name generated with %uSUFFIX, generating a
+ new one if there is no such last file name. In the absence of any
+ %uSUFFIX, this is just like %gSUFFIX, except they don't share
+ the same suffix "space", so `%g.s ... %U.s ... %g.s ... %U.s'
+ would involve the generation of two distinct file names, one
+ for each `%g.s' and another for each `%U.s'. Previously, %U was
+ simply substituted with a file name chosen for the previous %u,
+ without regard to any appended suffix.
+ %jSUFFIX
+ substitutes the name of the HOST_BIT_BUCKET, if any, and if it is
+ writable, and if save-temps is off; otherwise, substitute the name
+ of a temporary file, just like %u. This temporary file is not
+ meant for communication between processes, but rather as a junk
+ disposal mechanism.
+ %.SUFFIX
+ substitutes .SUFFIX for the suffixes of a matched switch's args when
+ it is subsequently output with %*. SUFFIX is terminated by the next
+ space or %.
+ %d marks the argument containing or following the %d as a
+ temporary file name, so that file will be deleted if GCC exits
+ successfully. Unlike %g, this contributes no text to the argument.
+ %w marks the argument containing or following the %w as the
+ "output file" of this compilation. This puts the argument
+ into the sequence of arguments that %o will substitute later.
+ %V indicates that this compilation produces no "output file".
+ %W{...}
+ like %{...} but marks the last argument supplied within as a file
+ to be deleted on failure.
+ %@{...}
+ like %{...} but puts the result into a FILE and substitutes @FILE
+ if an @file argument has been supplied.
+ %o substitutes the names of all the output files, with spaces
+ automatically placed around them. You should write spaces
+ around the %o as well or the results are undefined.
+ %o is for use in the specs for running the linker.
+ Input files whose names have no recognized suffix are not compiled
+ at all, but they are included among the output files, so they will
+ be linked.
+ %O substitutes the suffix for object files. Note that this is
+ handled specially when it immediately follows %g, %u, or %U
+ (with or without a suffix argument) 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 support additional
+ SUFFIX characters following %O as they would following, for
+ example, `.o'.
+ %I Substitute any of -iprefix (made from GCC_EXEC_PREFIX), -isysroot
+ (made from TARGET_SYSTEM_ROOT), -isystem (made from COMPILER_PATH
+ and -B options) and -imultilib as necessary.
+ %s current argument is the name of a library or startup file of some sort.
+ Search for that file in a standard list of directories
+ and substitute the full name found.
+ %T current argument is the name of a linker script.
+ Search for that file in the current list of directories to scan for
+ libraries. If the file is located, insert a --script option into the
+ command line followed by the full path name found. If the file is
+ not found then generate an error message.
+ Note: the current working directory is not searched.
+ %eSTR Print STR as an error message. STR is terminated by a newline.
+ Use this when inconsistent options are detected.
+ %nSTR Print STR as a notice. STR is terminated by a newline.
+ %x{OPTION} Accumulate an option for %X.
+ %X Output the accumulated linker options specified by compilations.
+ %Y Output the accumulated assembler options specified by compilations.
+ %Z Output the accumulated preprocessor options specified by compilations.
+ %a process ASM_SPEC as a spec.
+ This allows config.h to specify part of the spec for running as.
+ %A process ASM_FINAL_SPEC as a spec. A capital A is actually
+ used here. This can be used to run a post-processor after the
+ assembler has done its job.
+ %D Dump out a -L option for each directory in startfile_prefixes.
+ If multilib_dir is set, extra entries are generated with it affixed.
+ %l process LINK_SPEC as a spec.
+ %L process LIB_SPEC as a spec.
+ %M Output multilib_os_dir.
+ %G process LIBGCC_SPEC as a spec.
+ %R Output the concatenation of target_system_root and
+ target_sysroot_suffix.
+ %S process STARTFILE_SPEC as a spec. A capital S is actually used here.
+ %E process ENDFILE_SPEC as a spec. A capital E is actually used here.
+ %C process CPP_SPEC as a spec.
+ %1 process CC1_SPEC as a spec.
+ %2 process CC1PLUS_SPEC as a spec.
+ %* substitute the variable part of a matched option. (See below.)
+ Note that each comma in the substituted string is replaced by
+ a single space. A space is appended after the last substition
+ unless there is more text in current sequence.
+ %<S remove all occurrences of -S from the command line.
+ Note - this command is position dependent. % commands in the
+ spec string before this one will see -S, % commands in the
+ spec string after this one will not.
+ %>S Similar to "%<S", but keep it in the GCC command line.
+ %<S* remove all occurrences of all switches beginning with -S from the
+ command line.
+ %:function(args)
+ Call the named function FUNCTION, passing it ARGS. ARGS is
+ first processed as a nested spec string, then split into an
+ argument vector in the usual fashion. The function returns
+ a string which is processed as if it had appeared literally
+ as part of the current spec.
+ %{S} substitutes the -S switch, if that switch was given to GCC.
+ If that switch was not specified, this substitutes nothing.
+ Here S is a metasyntactic variable.
+ %{S*} substitutes all the switches specified to GCC whose names start
+ with -S. This is used for -o, -I, etc; switches that take
+ arguments. GCC 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*&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 the -S switch was given to GCC.
+ %{!S:X} substitutes X, if the -S switch was NOT given to GCC.
+ %{S*:X} substitutes X if one or more switches whose names start
+ with -S was given to GCC. Normally X is substituted only
+ once, no matter how many such switches appeared. However,
+ if %* appears somewhere in X, then X will be substituted
+ once for each matching switch, with the %* replaced by the
+ part of that switch that matched the '*'. A space will be
+ appended after the last substition unless there is more
+ text in current sequence.
+ %{.S:X} substitutes X, if processing a file with suffix S.
+ %{!.S:X} substitutes X, if NOT processing a file with suffix S.
+ %{,S:X} substitutes X, if processing a file which will use spec S.
+ %{!,S:X} substitutes X, if NOT processing a file which will use spec S.
+
+ %{S|T:X} substitutes X if either -S or -T was given to GCC. This may be
+ combined with '!', '.', ',', and '*' as above binding stronger
+ than the OR.
+ If %* appears in X, all of the alternatives must be starred, and
+ only the first matching alternative is substituted.
+ %{%:function(args):X}
+ Call function named FUNCTION with args ARGS. If the function
+ returns non-NULL, then X is substituted, if it returns
+ NULL, it isn't substituted.
+ %{S:X; if S was given to GCC, substitutes X;
+ T:Y; else if T was given to GCC, substitutes Y;
+ :D} else substitutes D. There can be as many clauses as you need.
+ This may be combined with '.', '!', ',', '|', and '*' as above.
+
+ %(Spec) processes a specification defined in a specs file as *Spec:
+
+ The switch matching text S in a %{S}, %{S:X}, or similar construct can use
+ a backslash to ignore the special meaning of the character following it,
+ thus allowing literal matching of a character that is otherwise specially
+ treated. For example, %{std=iso9899\:1999:X} substitutes X if the
+ -std=iso9899:1999 option is given.
+
+ The conditional text X in a %{S:X} or similar construct may contain
+ other nested % constructs or spaces, or even newlines. They are
+ processed as usual, as described above. Trailing white space in X is
+ ignored. White space may also appear anywhere on the left side of the
+ colon in these constructs, except between . or * and the corresponding
+ word.
+
+ The -O, -f, -g, -m, and -W switches are handled specifically in these
+ constructs. If another value of -O or the negated form of a -f, -m, or
+ -W switch is found later in the command line, the earlier switch
+ value is ignored, except with {S*} where S is just one letter; this
+ passes all matching options.
+
+ The character | at the beginning of the predicate text is used to indicate
+ that a command should be piped to the following command, but only if -pipe
+ is specified.
+
+ Note that it is built into GCC which switches take arguments and which
+ do not. You might think it would be useful to generalize this to
+ allow each compiler's spec to say which switches take arguments. But
+ this cannot be done in a consistent fashion. GCC cannot even decide
+ which input files have been specified without knowing which switches
+ take arguments, and it must know which input files to compile in order
+ to tell which compilers to run.
+
+ GCC also knows implicitly that arguments starting in `-l' are to be
+ treated as compiler output files, and passed to the linker in their
+ proper position among the other output files. */

+ name is not given, but when they're intermediate outputs, they
+ are named like other aux outputs, so the options affect their
+ location and name.
+
+ Here are some examples. There are several more in the
+ documentation of -o and -dump*, and some quite exhaustive tests
+ in gcc.misc-tests/outputs.exp.
+
+ When compiling any number of sources, no -dump* nor
+ -save-temps=*, all outputs in cwd without prefix:
+
+ # gcc -c b.c -gsplit-dwarf
+ -> cc1 [-dumpdir ./] -dumpbase b.c -dumpbase-ext .c # b.o b.dwo
+
+ # gcc -c b.c d.c -gsplit-dwarf
+ -> cc1 [-dumpdir ./] -dumpbase b.c -dumpbase-ext .c # b.o b.dwo
+ && cc1 [-dumpdir ./] -dumpbase d.c -dumpbase-ext .c # d.o d.dwo
+
+ When compiling and linking, no -dump* nor -save-temps=*, .o
+ outputs are temporary, aux outputs land in the dir of the output,
+ prefixed with the basename of the linker output:
+
+ # gcc b.c d.c -o ab -gsplit-dwarf
+ -> cc1 -dumpdir ab- -dumpbase b.c -dumpbase-ext .c # ab-b.dwo
+ && cc1 -dumpdir ab- -dumpbase d.c -dumpbase-ext .c # ab-d.dwo
+ && link ... -o ab
+
+ # gcc b.c d.c [-o a.out] -gsplit-dwarf
+ -> cc1 -dumpdir a- -dumpbase b.c -dumpbase-ext .c # a-b.dwo
+ && cc1 -dumpdir a- -dumpbase d.c -dumpbase-ext .c # a-d.dwo
+ && link ... [-o a.out]
+
+ When compiling and linking, a prevailing -dumpdir fully overrides
+ the prefix of aux outputs given by the output name:
+
+ # gcc -dumpdir f b.c d.c -gsplit-dwarf [-o [dir/]whatever]
+ -> cc1 -dumpdir f -dumpbase b.c -dumpbase-ext .c # fb.dwo
+ && cc1 -dumpdir f -dumpbase d.c -dumpbase-ext .c # fd.dwo
+ && link ... [-o whatever]
+
+ When compiling multiple inputs, an explicit -dumpbase is combined
+ with -dumpdir, affecting aux outputs, but not the .o outputs:
+
+ # gcc -dumpdir f -dumpbase g- b.c d.c -gsplit-dwarf -c
+ -> cc1 -dumpdir fg- -dumpbase b.c -dumpbase-ext .c # b.o fg-b.dwo
+ && cc1 -dumpdir fg- -dumpbase d.c -dumpbase-ext .c # d.o fg-d.dwo
+
+ When compiling and linking with -save-temps, the .o outputs that
+ would have been temporary become aux outputs, so they get
+ affected by -dump* flags:
+
+ # gcc -dumpdir f -dumpbase g- -save-temps b.c d.c
+ -> cc1 -dumpdir fg- -dumpbase b.c -dumpbase-ext .c # fg-b.o
+ && cc1 -dumpdir fg- -dumpbase d.c -dumpbase-ext .c # fg-d.o
+ && link
+
+ If -save-temps=* prevails over -dumpdir, however, the explicit
+ -dumpdir is discarded, as if it wasn't there. The basename of
+ the implicit linker output, a.out or a.exe, becomes a- as the aux
+ output prefix for all compilations:
+
+ # gcc [-dumpdir f] -save-temps=cwd b.c d.c
+ -> cc1 -dumpdir a- -dumpbase b.c -dumpbase-ext .c # a-b.o
+ && cc1 -dumpdir a- -dumpbase d.c -dumpbase-ext .c # a-d.o
+ && link
+
+ A single -dumpbase, applying to multiple inputs, overrides the
+ linker output name, implied or explicit, as the aux output prefix:
+
+ # gcc [-dumpdir f] -dumpbase g- -save-temps=cwd b.c d.c
+ -> cc1 -dumpdir g- -dumpbase b.c -dumpbase-ext .c # g-b.o
+ && cc1 -dumpdir g- -dumpbase d.c -dumpbase-ext .c # g-d.o
+ && link
+
+ # gcc [-dumpdir f] -dumpbase g- -save-temps=cwd b.c d.c -o dir/h.out
+ -> cc1 -dumpdir g- -dumpbase b.c -dumpbase-ext .c # g-b.o
+ && cc1 -dumpdir g- -dumpbase d.c -dumpbase-ext .c # g-d.o
+ && link -o dir/h.out
+
+ Now, if the linker output is NOT overridden as a prefix, but
+ -save-temps=* overrides implicit or explicit -dumpdir, the
+ effective dump dir combines the dir selected by the -save-temps=*
+ option with the basename of the specified or implied link output:
+
+ # gcc [-dumpdir f] -save-temps=cwd b.c d.c -o dir/h.out
+ -> cc1 -dumpdir h- -dumpbase b.c -dumpbase-ext .c # h-b.o
+ && cc1 -dumpdir h- -dumpbase d.c -dumpbase-ext .c # h-d.o
+ && link -o dir/h.out
+
+ # gcc [-dumpdir f] -save-temps=obj b.c d.c -o dir/h.out
+ -> cc1 -dumpdir dir/h- -dumpbase b.c -dumpbase-ext .c # dir/h-b.o
+ && cc1 -dumpdir dir/h- -dumpbase d.c -dumpbase-ext .c # dir/h-d.o
+ && link -o dir/h.out
+
+ But then again, a single -dumpbase applying to multiple inputs
+ gets used instead of the linker output basename in the combined
+ dumpdir:
+
+ # gcc [-dumpdir f] -dumpbase g- -save-temps=obj b.c d.c -o dir/h.out
+ -> cc1 -dumpdir dir/g- -dumpbase b.c -dumpbase-ext .c # dir/g-b.o
+ && cc1 -dumpdir dir/g- -dumpbase d.c -dumpbase-ext .c # dir/g-d.o
+ && link -o dir/h.out
+
+ With a single input being compiled, the output basename does NOT
+ affect the dumpdir prefix.
+
+ # gcc -save-temps=obj b.c -gsplit-dwarf -c -o dir/b.o
+ -> cc1 -dumpdir dir/ -dumpbase b.c -dumpbase-ext .c # dir/b.o dir/b.dwo
+
+ but when compiling and linking even a single file, it does:
+
+ # gcc -save-temps=obj b.c -o dir/h.out
+ -> cc1 -dumpdir dir/h- -dumpbase b.c -dumpbase-ext .c # dir/h-b.o
+
+ unless an explicit -dumpdir prevails:
+
+ # gcc -save-temps[=obj] -dumpdir g- b.c -o dir/h.out
+ -> cc1 -dumpdir g- -dumpbase b.c -dumpbase-ext .c # g-b.o
