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(). */ | |

357 | /* The Specs Language |
358 | ||
359 | Specs are strings containing lines, each of which (if not blank) | |
ed1f651b RS |
360 | is made up of a program name, and arguments separated by spaces. |
361 | The program name must be exact and start from root, since no path | |
362 | is searched and it is unreliable to depend on the current working directory. | |
363 | Redirection of input or output is not supported; the subprograms must | |
364 | accept filenames saying what files to read and write. | |
365 | ||
366 | In addition, the specs can contain %-sequences to substitute variable text | |
367 | or for conditional text. Here is a table of all defined %-sequences. | |
368 | Note that spaces are not generated automatically around the results of | |
369 | expanding these sequences; therefore, you can concatenate them together | |
370 | or with constant text in a single argument. | |
371 | ||
372 | %% substitute one % into the program name or argument. | |
373 | %i substitute the name of the input file being processed. | |
374 | %b substitute the basename of the input file being processed. | |
375 | This is the substring up to (and not including) the last period | |
376 | and not including the directory. | |
ea414c97 | 377 | %B same as %b, but include the file suffix (text after the last period). |
dd75c292 CB |
378 | %gSUFFIX |
379 | substitute a file name that has suffix SUFFIX and is chosen | |
380 | once per compilation, and mark the argument a la %d. To reduce | |
381 | exposure to denial-of-service attacks, the file name is now | |
382 | chosen in a way that is hard to predict even when previously | |
383 | chosen file names are known. For example, `%g.s ... %g.o ... %g.s' | |
384 | might turn into `ccUVUUAU.s ccXYAXZ12.o ccUVUUAU.s'. SUFFIX matches | |
a1d9074c TT |
385 | the regexp "[.A-Za-z]*%O"; "%O" is treated exactly as if it |
386 | had been pre-processed. Previously, %g was simply substituted | |
387 | with a file name chosen once per compilation, without regard | |
388 | to any appended suffix (which was therefore treated just like | |
389 | ordinary text), making such attacks more likely to succeed. | |
4977bab6 ZW |
390 | %|SUFFIX |
391 | like %g, but if -pipe is in effect, expands simply to "-". | |
392 | %mSUFFIX | |
393 | like %g, but if -pipe is in effect, expands to nothing. (We have both | |
394 | %| and %m to accommodate differences between system assemblers; see | |
395 | the AS_NEEDS_DASH_FOR_PIPED_INPUT target macro.) | |
dd75c292 CB |
396 | %uSUFFIX |
397 | like %g, but generates a new temporary file name even if %uSUFFIX | |
398 | was already seen. | |
399 | %USUFFIX | |
400 | substitutes the last file name generated with %uSUFFIX, generating a | |
401 | new one if there is no such last file name. In the absence of any | |
402 | %uSUFFIX, this is just like %gSUFFIX, except they don't share | |
403 | the same suffix "space", so `%g.s ... %U.s ... %g.s ... %U.s' | |
404 | would involve the generation of two distinct file names, one | |
405 | for each `%g.s' and another for each `%U.s'. Previously, %U was | |
406 | simply substituted with a file name chosen for the previous %u, | |
407 | without regard to any appended suffix. | |
49009afd JL |
408 | %jSUFFIX |
409 | substitutes the name of the HOST_BIT_BUCKET, if any, and if it is | |
410 | writable, and if save-temps is off; otherwise, substitute the name | |
411 | of a temporary file, just like %u. This temporary file is not | |
412 | meant for communication between processes, but rather as a junk | |
413 | disposal mechanism. | |
11972f66 NS |
414 | %.SUFFIX |
415 | substitutes .SUFFIX for the suffixes of a matched switch's args when | |
416 | it is subsequently output with %*. SUFFIX is terminated by the next | |
417 | space or %. | |
ed1f651b RS |
418 | %d marks the argument containing or following the %d as a |
419 | temporary file name, so that that file will be deleted if CC exits | |
420 | successfully. Unlike %g, this contributes no text to the argument. | |
421 | %w marks the argument containing or following the %w as the | |
422 | "output file" of this compilation. This puts the argument | |
423 | into the sequence of arguments that %o will substitute later. | |
17211ab5 | 424 | %V indicates that this compilation produces no "output file". |
ed1f651b RS |
425 | %W{...} |
426 | like %{...} but mark last argument supplied within | |
427 | as a file to be deleted on failure. | |
428 | %o substitutes the names of all the output files, with spaces | |
429 | automatically placed around them. You should write spaces | |
430 | around the %o as well or the results are undefined. | |
431 | %o is for use in the specs for running the linker. | |
432 | Input files whose names have no recognized suffix are not compiled | |
433 | at all, but they are included among the output files, so they will | |
434 | be linked. | |
dd75c292 | 435 | %O substitutes the suffix for object files. Note that this is |
a1d9074c TT |
436 | handled specially when it immediately follows %g, %u, or %U |
437 | (with or without a suffix argument) because of the need for | |
438 | those to form complete file names. The handling is such that | |
439 | %O is treated exactly as if it had already been substituted, | |
440 | except that %g, %u, and %U do not currently support additional | |
441 | SUFFIX characters following %O as they would following, for | |
442 | example, `.o'. | |
ed1f651b RS |
443 | %p substitutes the standard macro predefinitions for the |
444 | current target machine. Use this when running cpp. | |
445 | %P like %p, but puts `__' before and after the name of each macro. | |
446 | (Except macros that already have __.) | |
447 | This is for ANSI C. | |
8eebb258 | 448 | %I Substitute a -iprefix option made from GCC_EXEC_PREFIX. |
ed1f651b RS |
449 | %s current argument is the name of a library or startup file of some sort. |
450 | Search for that file in a standard list of directories | |
451 | and substitute the full name found. | |
452 | %eSTR Print STR as an error message. STR is terminated by a newline. | |
453 | Use this when inconsistent options are detected. | |
09da1532 | 454 | %nSTR Print STR as a notice. STR is terminated by a newline. |
ed1f651b RS |
455 | %x{OPTION} Accumulate an option for %X. |
456 | %X Output the accumulated linker options specified by compilations. | |
c9ebacb8 | 457 | %Y Output the accumulated assembler options specified by compilations. |
57cb9b60 | 458 | %Z Output the accumulated preprocessor options specified by compilations. |
500c9e81 | 459 | %v1 Substitute the major version number of GCC. |
3ea8083f | 460 | (For version 2.5.3, this is 2.) |
500c9e81 | 461 | %v2 Substitute the minor version number of GCC. |
3ea8083f JL |
462 | (For version 2.5.3, this is 5.) |
463 | %v3 Substitute the patch level number of GCC. | |
464 | (For version 2.5.3, this is 3.) | |
ed1f651b RS |
465 | %a process ASM_SPEC as a spec. |
466 | This allows config.h to specify part of the spec for running as. | |
467 | %A process ASM_FINAL_SPEC as a spec. A capital A is actually | |
468 | used here. This can be used to run a post-processor after the | |
9ec36da5 | 469 | assembler has done its job. |
48ff801b | 470 | %D Dump out a -L option for each directory in startfile_prefixes. |
60103a34 | 471 | If multilib_dir is set, extra entries are generated with it affixed. |
ed1f651b RS |
472 | %l process LINK_SPEC as a spec. |
473 | %L process LIB_SPEC as a spec. | |
68d69835 | 474 | %G process LIBGCC_SPEC as a spec. |
9db0819e RH |
475 | %M output multilib_dir with directory separators replaced with "_"; |
476 | if multilib_dir is not set or is ".", output "". | |
ed1f651b RS |
477 | %S process STARTFILE_SPEC as a spec. A capital S is actually used here. |
478 | %E process ENDFILE_SPEC as a spec. A capital E is actually used here. | |
9db0819e | 479 | %C process CPP_SPEC as a spec. |
ed1f651b RS |
480 | %1 process CC1_SPEC as a spec. |
481 | %2 process CC1PLUS_SPEC as a spec. | |
482 | %* substitute the variable part of a matched option. (See below.) | |
483 | Note that each comma in the substituted string is replaced by | |
484 | a single space. | |
4977bab6 ZW |
485 | %<S remove all occurrences of -S from the command line. |
486 | Note - this command is position dependent. % commands in the | |
487 | spec string before this one will see -S, % commands in the | |
488 | spec string after this one will not. | |
489 | %<S* remove all occurrences of all switches beginning with -S from the | |
490 | command line. | |
f3226a90 JT |
491 | %:function(args) |
492 | Call the named function FUNCTION, passing it ARGS. ARGS is | |
493 | first processed as a nested spec string, then split into an | |
494 | argument vector in the usual fashion. The function returns | |
495 | a string which is processed as if it had appeared literally | |
496 | as part of the current spec. | |
ed1f651b RS |
497 | %{S} substitutes the -S switch, if that switch was given to CC. |
498 | If that switch was not specified, this substitutes nothing. | |
499 | Here S is a metasyntactic variable. | |
500 | %{S*} substitutes all the switches specified to CC whose names start | |
196a37f4 | 501 | with -S. This is used for -o, -I, etc; switches that take |
ed1f651b RS |
502 | arguments. CC considers `-o foo' as being one switch whose |
503 | name starts with `o'. %{o*} would substitute this text, | |
504 | including the space; thus, two arguments would be generated. | |
196a37f4 NB |
505 | %{S*&T*} likewise, but preserve order of S and T options (the order |
506 | of S and T in the spec is not significant). Can be any number | |
507 | of ampersand-separated variables; for each the wild card is | |
508 | optional. Useful for CPP as %{D*&U*&A*}. | |
4977bab6 ZW |
509 | |
510 | %{S:X} substitutes X, if the -S switch was given to CC. | |
511 | %{!S:X} substitutes X, if the -S switch was NOT given to CC. | |
512 | %{S*:X} substitutes X if one or more switches whose names start | |
513 | with -S was given to CC. Normally X is substituted only | |
514 | once, no matter how many such switches appeared. However, | |
515 | if %* appears somewhere in X, then X will be substituted | |
516 | once for each matching switch, with the %* replaced by the | |
517 | part of that switch that matched the '*'. | |
518 | %{.S:X} substitutes X, if processing a file with suffix S. | |
519 | %{!.S:X} substitutes X, if NOT processing a file with suffix S. | |
520 | ||
521 | %{S|T:X} substitutes X if either -S or -T was given to CC. This may be | |
522 | combined with !, ., and * as above binding stronger than the OR. | |
523 | If %* appears in X, all of the alternatives must be starred, and | |
524 | only the first matching alternative is substituted. | |
525 | %{S:X; if S was given to CC, substitutes X; | |
526 | T:Y; else if T was given to CC, substitutes Y; | |
527 | :D} else substitutes D. There can be as many clauses as you need. | |
528 | This may be combined with ., !, |, and * as above. | |
529 | ||
b3865ca9 | 530 | %(Spec) processes a specification defined in a specs file as *Spec: |
4089dfab | 531 | %[Spec] as above, but put __ around -D arguments |
ed1f651b | 532 | |
4977bab6 | 533 | The conditional text X in a %{S:X} or similar construct may contain |
ed1f651b | 534 | other nested % constructs or spaces, or even newlines. They are |
4977bab6 ZW |
535 | processed as usual, as described above. Trailing white space in X is |
536 | ignored. White space may also appear anywhere on the left side of the | |
537 | colon in these constructs, except between . or * and the corresponding | |
538 | word. | |
ed1f651b | 539 | |
6c396fb5 | 540 | The -O, -f, -m, and -W switches are handled specifically in these |
f5b0eb4e RK |
541 | constructs. If another value of -O or the negated form of a -f, -m, or |
542 | -W switch is found later in the command line, the earlier switch | |
6c396fb5 RK |
543 | value is ignored, except with {S*} where S is just one letter; this |
544 | passes all matching options. | |
f5b0eb4e | 545 | |
9bf09437 RH |
546 | The character | at the beginning of the predicate text is used to indicate |
547 | that a command should be piped to the following command, but only if -pipe | |
548 | is specified. | |
ed1f651b RS |
549 | |
550 | Note that it is built into CC which switches take arguments and which | |
551 | do not. You might think it would be useful to generalize this to | |
552 | allow each compiler's spec to say which switches take arguments. But | |
553 | this cannot be done in a consistent fashion. CC cannot even decide | |
554 | which input files have been specified without knowing which switches | |
555 | take arguments, and it must know which input files to compile in order | |
556 | to tell which compilers to run. | |
557 | ||
558 | CC also knows implicitly that arguments starting in `-l' are to be | |
559 | treated as compiler output files, and passed to the linker in their | |
560 | proper position among the other output files. */ | |
