25 | /* This program is the user interface to the C compiler and possibly to | |
26 | other compilers. It is used because compilation is a complicated procedure | |
27 | which involves running several programs and passing temporary files between | |
28 | them, forwarding the users switches to those programs selectively, | |
29 | and deleting the temporary files at the end. | |
30 | ||
31 | CC recognizes how to compile each input file by suffixes in the file names. | |
32 | Once it knows which kind of compilation to perform, the procedure for | |
33 | compilation is specified by a string called a "spec". */ | |

35 | /* A Short Introduction to Adding a Command-Line Option. |
36 | ||
37 | Before adding a command-line option, consider if it is really | |
38 | necessary. Each additional command-line option adds complexity and | |
39 | is difficult to remove in subsequent versions. | |
40 | ||
41 | In the following, consider adding the command-line argument | |
42 | `--bar'. | |
43 | ||
44 | 1. Each command-line option is specified in the specs file. The | |
45 | notation is described below in the comment entitled "The Specs | |
46 | Language". Read it. | |
47 | ||
48 | 2. In this file, add an entry to "option_map" equating the long | |
49 | `--' argument version and any shorter, single letter version. Read | |
50 | the comments in the declaration of "struct option_map" for an | |
51 | explanation. Do not omit the first `-'. | |
52 | ||
53 | 3. Look in the "specs" file to determine which program or option | |
54 | list should be given the argument, e.g., "cc1_options". Add the | |
55 | appropriate syntax for the shorter option version to the | |
56 | corresponding "const char *" entry in this file. Omit the first | |
57 | `-' from the option. For example, use `-bar', rather than `--bar'. | |
58 | ||
59 | 4. If the argument takes an argument, e.g., `--baz argument1', | |
60 | modify either DEFAULT_SWITCH_TAKES_ARG or | |
61 | DEFAULT_WORD_SWITCH_TAKES_ARG in this file. Omit the first `-' | |
62 | from `--baz'. | |
63 | ||
64 | 5. Document the option in this file's display_help(). If the | |
65 | option is passed to a subprogram, modify its corresponding | |
66 | function, e.g., cppinit.c:print_help() or toplev.c:display_help(), | |
67 | instead. | |
68 | ||
69 | 6. Compile and test. Make sure that your new specs file is being | |
70 | read. For example, use a debugger to investigate the value of | |
71 | "specs_file" in main(). */ | |

333 | /* The Specs Language |
334 | ||
335 | Specs are strings containing lines, each of which (if not blank) | |
ed1f651b RS |
336 | is made up of a program name, and arguments separated by spaces. |
337 | The program name must be exact and start from root, since no path | |
338 | is searched and it is unreliable to depend on the current working directory. | |
339 | Redirection of input or output is not supported; the subprograms must | |
340 | accept filenames saying what files to read and write. | |
341 | ||
342 | In addition, the specs can contain %-sequences to substitute variable text | |
343 | or for conditional text. Here is a table of all defined %-sequences. | |
344 | Note that spaces are not generated automatically around the results of | |
345 | expanding these sequences; therefore, you can concatenate them together | |
346 | or with constant text in a single argument. | |
347 | ||
348 | %% substitute one % into the program name or argument. | |
349 | %i substitute the name of the input file being processed. | |
350 | %b substitute the basename of the input file being processed. | |
351 | This is the substring up to (and not including) the last period | |
352 | and not including the directory. | |
ea414c97 | 353 | %B same as %b, but include the file suffix (text after the last period). |
dd75c292 CB |
354 | %gSUFFIX |
355 | substitute a file name that has suffix SUFFIX and is chosen | |
356 | once per compilation, and mark the argument a la %d. To reduce | |
357 | exposure to denial-of-service attacks, the file name is now | |
358 | chosen in a way that is hard to predict even when previously | |
359 | chosen file names are known. For example, `%g.s ... %g.o ... %g.s' | |
360 | might turn into `ccUVUUAU.s ccXYAXZ12.o ccUVUUAU.s'. SUFFIX matches | |
a1d9074c TT |
361 | the regexp "[.A-Za-z]*%O"; "%O" is treated exactly as if it |
362 | had been pre-processed. Previously, %g was simply substituted | |
363 | with a file name chosen once per compilation, without regard | |
364 | to any appended suffix (which was therefore treated just like | |
365 | ordinary text), making such attacks more likely to succeed. | |
dd75c292 CB |
366 | %uSUFFIX |
367 | like %g, but generates a new temporary file name even if %uSUFFIX | |
368 | was already seen. | |
369 | %USUFFIX | |
370 | substitutes the last file name generated with %uSUFFIX, generating a | |
371 | new one if there is no such last file name. In the absence of any | |
372 | %uSUFFIX, this is just like %gSUFFIX, except they don't share | |
373 | the same suffix "space", so `%g.s ... %U.s ... %g.s ... %U.s' | |
374 | would involve the generation of two distinct file names, one | |
375 | for each `%g.s' and another for each `%U.s'. Previously, %U was | |
376 | simply substituted with a file name chosen for the previous %u, | |
377 | without regard to any appended suffix. | |
49009afd JL |
378 | %jSUFFIX |
379 | substitutes the name of the HOST_BIT_BUCKET, if any, and if it is | |
380 | writable, and if save-temps is off; otherwise, substitute the name | |
381 | of a temporary file, just like %u. This temporary file is not | |
382 | meant for communication between processes, but rather as a junk | |
383 | disposal mechanism. | |
11972f66 NS |
384 | %.SUFFIX |
385 | substitutes .SUFFIX for the suffixes of a matched switch's args when | |
386 | it is subsequently output with %*. SUFFIX is terminated by the next | |
387 | space or %. | |
ed1f651b RS |
388 | %d marks the argument containing or following the %d as a |
389 | temporary file name, so that that file will be deleted if CC exits | |
390 | successfully. Unlike %g, this contributes no text to the argument. | |
391 | %w marks the argument containing or following the %w as the | |
392 | "output file" of this compilation. This puts the argument | |
393 | into the sequence of arguments that %o will substitute later. | |
394 | %W{...} | |
395 | like %{...} but mark last argument supplied within | |
396 | as a file to be deleted on failure. | |
397 | %o substitutes the names of all the output files, with spaces | |
398 | automatically placed around them. You should write spaces | |
399 | around the %o as well or the results are undefined. | |
400 | %o is for use in the specs for running the linker. | |
401 | Input files whose names have no recognized suffix are not compiled | |
402 | at all, but they are included among the output files, so they will | |
403 | be linked. | |
dd75c292 | 404 | %O substitutes the suffix for object files. Note that this is |
a1d9074c TT |
405 | handled specially when it immediately follows %g, %u, or %U |
406 | (with or without a suffix argument) because of the need for | |
407 | those to form complete file names. The handling is such that | |
408 | %O is treated exactly as if it had already been substituted, | |
409 | except that %g, %u, and %U do not currently support additional | |
410 | SUFFIX characters following %O as they would following, for | |
411 | example, `.o'. | |
ed1f651b RS |
412 | %p substitutes the standard macro predefinitions for the |
413 | current target machine. Use this when running cpp. | |
414 | %P like %p, but puts `__' before and after the name of each macro. | |
415 | (Except macros that already have __.) | |
416 | This is for ANSI C. | |
8eebb258 | 417 | %I Substitute a -iprefix option made from GCC_EXEC_PREFIX. |
ed1f651b RS |
418 | %s current argument is the name of a library or startup file of some sort. |
419 | Search for that file in a standard list of directories | |
420 | and substitute the full name found. | |
421 | %eSTR Print STR as an error message. STR is terminated by a newline. | |
422 | Use this when inconsistent options are detected. | |
4a88a060 | 423 | %nSTR Print STR as an notice. STR is terminated by a newline. |
ed1f651b RS |
424 | %x{OPTION} Accumulate an option for %X. |
425 | %X Output the accumulated linker options specified by compilations. | |
c9ebacb8 | 426 | %Y Output the accumulated assembler options specified by compilations. |
57cb9b60 | 427 | %Z Output the accumulated preprocessor options specified by compilations. |
500c9e81 | 428 | %v1 Substitute the major version number of GCC. |
3ea8083f | 429 | (For version 2.5.3, this is 2.) |
500c9e81 | 430 | %v2 Substitute the minor version number of GCC. |
3ea8083f JL |
431 | (For version 2.5.3, this is 5.) |
432 | %v3 Substitute the patch level number of GCC. | |
433 | (For version 2.5.3, this is 3.) | |
ed1f651b RS |
434 | %a process ASM_SPEC as a spec. |
435 | This allows config.h to specify part of the spec for running as. | |
436 | %A process ASM_FINAL_SPEC as a spec. A capital A is actually | |
437 | used here. This can be used to run a post-processor after the | |
9ec36da5 | 438 | assembler has done its job. |
48ff801b | 439 | %D Dump out a -L option for each directory in startfile_prefixes. |
60103a34 | 440 | If multilib_dir is set, extra entries are generated with it affixed. |
ed1f651b RS |
441 | %l process LINK_SPEC as a spec. |
442 | %L process LIB_SPEC as a spec. | |
68d69835 | 443 | %G process LIBGCC_SPEC as a spec. |
9db0819e RH |
444 | %M output multilib_dir with directory separators replaced with "_"; |
445 | if multilib_dir is not set or is ".", output "". | |
ed1f651b RS |
446 | %S process STARTFILE_SPEC as a spec. A capital S is actually used here. |
447 | %E process ENDFILE_SPEC as a spec. A capital E is actually used here. | |
448 | %c process SIGNED_CHAR_SPEC as a spec. | |
9db0819e | 449 | %C process CPP_SPEC as a spec. |
ed1f651b RS |
450 | %1 process CC1_SPEC as a spec. |
451 | %2 process CC1PLUS_SPEC as a spec. | |
a99bf70c | 452 | %| output "-" if the input for the current command is coming from a pipe. |
ed1f651b RS |
453 | %* substitute the variable part of a matched option. (See below.) |
454 | Note that each comma in the substituted string is replaced by | |
455 | a single space. | |
456 | %{S} substitutes the -S switch, if that switch was given to CC. | |
457 | If that switch was not specified, this substitutes nothing. | |
458 | Here S is a metasyntactic variable. | |
459 | %{S*} substitutes all the switches specified to CC whose names start | |
196a37f4 | 460 | with -S. This is used for -o, -I, etc; switches that take |
ed1f651b RS |
461 | arguments. CC considers `-o foo' as being one switch whose |
462 | name starts with `o'. %{o*} would substitute this text, | |
463 | including the space; thus, two arguments would be generated. | |
9f3c45fd | 464 | %{^S*} likewise, but don't put a blank between a switch and any args. |
196a37f4 NB |
465 | %{S*&T*} likewise, but preserve order of S and T options (the order |
466 | of S and T in the spec is not significant). Can be any number | |
467 | of ampersand-separated variables; for each the wild card is | |
468 | optional. Useful for CPP as %{D*&U*&A*}. | |
b9490a6e | 469 | %{S*:X} substitutes X if one or more switches whose names start with -S are |
ed1f651b RS |
470 | specified to CC. Note that the tail part of the -S option |
471 | (i.e. the part matched by the `*') will be substituted for each | |
6dc42e49 | 472 | occurrence of %* within X. |
ff7cc307 | 473 | %{<S} remove all occurrences of -S from the command line. |
8097c429 | 474 | Note - this option is position dependent. % commands in the |
50c57e7b | 475 | spec string before this option will see -S, % commands in the |
8097c429 | 476 | spec string after this option will not. |
ed1f651b RS |
477 | %{S:X} substitutes X, but only if the -S switch was given to CC. |
478 | %{!S:X} substitutes X, but only if the -S switch was NOT given to CC. | |
479 | %{|S:X} like %{S:X}, but if no S switch, substitute `-'. | |
480 | %{|!S:X} like %{!S:X}, but if there is an S switch, substitute `-'. | |
481 | %{.S:X} substitutes X, but only if processing a file with suffix S. | |
482 | %{!.S:X} substitutes X, but only if NOT processing a file with suffix S. | |
9bf09437 RH |
483 | %{S|P:X} substitutes X if either -S or -P was given to CC. This may be |
484 | combined with ! and . as above binding stronger than the OR. | |
b3865ca9 | 485 | %(Spec) processes a specification defined in a specs file as *Spec: |
4089dfab | 486 | %[Spec] as above, but put __ around -D arguments |
ed1f651b RS |
487 | |
488 | The conditional text X in a %{S:X} or %{!S:X} construct may contain | |
489 | other nested % constructs or spaces, or even newlines. They are | |
490 | processed as usual, as described above. | |
491 | ||
6c396fb5 | 492 | The -O, -f, -m, and -W switches are handled specifically in these |
f5b0eb4e RK |
493 | constructs. If another value of -O or the negated form of a -f, -m, or |
494 | -W switch is found later in the command line, the earlier switch | |
6c396fb5 RK |
495 | value is ignored, except with {S*} where S is just one letter; this |
496 | passes all matching options. | |
f5b0eb4e | 497 | |
9bf09437 RH |
498 | The character | at the beginning of the predicate text is used to indicate |
499 | that a command should be piped to the following command, but only if -pipe | |
500 | is specified. | |
ed1f651b RS |
501 | |
502 | Note that it is built into CC which switches take arguments and which | |
503 | do not. You might think it would be useful to generalize this to | |
504 | allow each compiler's spec to say which switches take arguments. But | |
505 | this cannot be done in a consistent fashion. CC cannot even decide | |
506 | which input files have been specified without knowing which switches | |
507 | take arguments, and it must know which input files to compile in order | |
508 | to tell which compilers to run. | |
509 | ||
510 | CC also knows implicitly that arguments starting in `-l' are to be | |
511 | treated as compiler output files, and passed to the linker in their | |
512 | proper position among the other output files. */ | |
