| /* This program is the user interface to the C compiler and possibly to |
| other compilers. It is used because compilation is a complicated procedure |
| which involves running several programs and passing temporary files between |
| them, forwarding the users switches to those programs selectively, |
| and deleting the temporary files at the end. |
| |
| CC recognizes how to compile each input file by suffixes in the file names. |
| Once it knows which kind of compilation to perform, the procedure for |
| compilation is specified by a string called a "spec". */ |
| |
| /* 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(). */ |

| /* 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. |
| %i substitute the name of the input file being processed. |
| %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 |
| 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 "[.A-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 that file will be deleted if CC 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 mark last argument supplied within |
| as a file to be deleted on failure. |
| %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), and -isystem (made from COMPILER_PATH |
| and -B options) as necessary. |
| APPLE LOCAL frameworks |
| %Q Substitute -iframework default paths. |
| %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. |
| %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. |
| %G process LIBGCC_SPEC as a spec. |
| %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. |
| %<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* 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 CC. |
| 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, -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*&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 CC. |
| %{!S:X} substitutes X, if the -S switch was NOT given to CC. |
| %{S*:X} substitutes X if one or more switches whose names start |
| with -S was given to CC. 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 '*'. |
| %{.S:X} substitutes X, if processing a file with suffix S. |
| %{!.S:X} substitutes X, if NOT processing a file with suffix S. |
| APPLE LOCAL begin mainline 2007-03-13 5040758 |
| %{,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 CC. 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. |
| %{S:X; if S was given to CC, substitutes X; |
| T:Y; else if T was given to CC, substitutes Y; |
| :D} else substitutes D. There can be as many clauses as you need. |
| This may be combined with '.', '!', ',', '|', and '*' as above. |
| APPLE LOCAL end mainline 2007-03-13 5040758 |
| |
| %(Spec) processes a specification defined in a specs file as *Spec: |
| %[Spec] as above, but put __ around -D arguments |
| |
| 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, -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 CC 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. CC 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. |
| |
| CC 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. */ |
