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

33 | /* A Short Introduction to Adding a Command-Line Option. |
34 | ||
35 | Before adding a command-line option, consider if it is really | |
36 | necessary. Each additional command-line option adds complexity and | |
37 | is difficult to remove in subsequent versions. | |
38 | ||
39 | In the following, consider adding the command-line argument | |
40 | `--bar'. | |
41 | ||
42 | 1. Each command-line option is specified in the specs file. The | |
43 | notation is described below in the comment entitled "The Specs | |
44 | Language". Read it. | |
45 | ||
46 | 2. In this file, add an entry to "option_map" equating the long | |
47 | `--' argument version and any shorter, single letter version. Read | |
48 | the comments in the declaration of "struct option_map" for an | |
49 | explanation. Do not omit the first `-'. | |
50 | ||
51 | 3. Look in the "specs" file to determine which program or option | |
52 | list should be given the argument, e.g., "cc1_options". Add the | |
53 | appropriate syntax for the shorter option version to the | |
54 | corresponding "const char *" entry in this file. Omit the first | |
55 | `-' from the option. For example, use `-bar', rather than `--bar'. | |
56 | ||
57 | 4. If the argument takes an argument, e.g., `--baz argument1', | |
58 | modify either DEFAULT_SWITCH_TAKES_ARG or | |
8ecf5a68 | 59 | DEFAULT_WORD_SWITCH_TAKES_ARG in gcc.h. Omit the first `-' |
d991c721 BK |
60 | from `--baz'. |
61 | ||
62 | 5. Document the option in this file's display_help(). If the | |
63 | option is passed to a subprogram, modify its corresponding | |
64 | function, e.g., cppinit.c:print_help() or toplev.c:display_help(), | |
65 | instead. | |
66 | ||
67 | 6. Compile and test. Make sure that your new specs file is being | |
68 | read. For example, use a debugger to investigate the value of | |
69 | "specs_file" in main(). */ | |

329 | /* The Specs Language |
330 | ||
331 | Specs are strings containing lines, each of which (if not blank) | |
ed1f651b RS |
332 | is made up of a program name, and arguments separated by spaces. |
333 | The program name must be exact and start from root, since no path | |
334 | is searched and it is unreliable to depend on the current working directory. | |
335 | Redirection of input or output is not supported; the subprograms must | |
336 | accept filenames saying what files to read and write. | |
337 | ||
338 | In addition, the specs can contain %-sequences to substitute variable text | |
339 | or for conditional text. Here is a table of all defined %-sequences. | |
340 | Note that spaces are not generated automatically around the results of | |
341 | expanding these sequences; therefore, you can concatenate them together | |
342 | or with constant text in a single argument. | |
343 | ||
344 | %% substitute one % into the program name or argument. | |
345 | %i substitute the name of the input file being processed. | |
346 | %b substitute the basename of the input file being processed. | |
347 | This is the substring up to (and not including) the last period | |
14fdc613 | 348 | and not including the directory unless -save-temps was specified |
3beb864c | 349 | to put temporaries in a different location. |
ea414c97 | 350 | %B same as %b, but include the file suffix (text after the last period). |
dd75c292 CB |
351 | %gSUFFIX |
352 | substitute a file name that has suffix SUFFIX and is chosen | |
353 | once per compilation, and mark the argument a la %d. To reduce | |
354 | exposure to denial-of-service attacks, the file name is now | |
355 | chosen in a way that is hard to predict even when previously | |
356 | chosen file names are known. For example, `%g.s ... %g.o ... %g.s' | |
357 | might turn into `ccUVUUAU.s ccXYAXZ12.o ccUVUUAU.s'. SUFFIX matches | |
a92dd235 | 358 | the regexp "[.0-9A-Za-z]*%O"; "%O" is treated exactly as if it |
a1d9074c TT |
359 | had been pre-processed. Previously, %g was simply substituted |
360 | with a file name chosen once per compilation, without regard | |
361 | to any appended suffix (which was therefore treated just like | |
362 | ordinary text), making such attacks more likely to succeed. | |
4977bab6 ZW |
363 | %|SUFFIX |
364 | like %g, but if -pipe is in effect, expands simply to "-". | |
365 | %mSUFFIX | |
366 | like %g, but if -pipe is in effect, expands to nothing. (We have both | |
367 | %| and %m to accommodate differences between system assemblers; see | |
368 | the AS_NEEDS_DASH_FOR_PIPED_INPUT target macro.) | |
dd75c292 CB |
369 | %uSUFFIX |
370 | like %g, but generates a new temporary file name even if %uSUFFIX | |
371 | was already seen. | |
372 | %USUFFIX | |
373 | substitutes the last file name generated with %uSUFFIX, generating a | |
374 | new one if there is no such last file name. In the absence of any | |
375 | %uSUFFIX, this is just like %gSUFFIX, except they don't share | |
376 | the same suffix "space", so `%g.s ... %U.s ... %g.s ... %U.s' | |
377 | would involve the generation of two distinct file names, one | |
378 | for each `%g.s' and another for each `%U.s'. Previously, %U was | |
379 | simply substituted with a file name chosen for the previous %u, | |
380 | without regard to any appended suffix. | |
49009afd JL |
381 | %jSUFFIX |
382 | substitutes the name of the HOST_BIT_BUCKET, if any, and if it is | |
383 | writable, and if save-temps is off; otherwise, substitute the name | |
384 | of a temporary file, just like %u. This temporary file is not | |
385 | meant for communication between processes, but rather as a junk | |
386 | disposal mechanism. | |
11972f66 NS |
387 | %.SUFFIX |
388 | substitutes .SUFFIX for the suffixes of a matched switch's args when | |
389 | it is subsequently output with %*. SUFFIX is terminated by the next | |
390 | space or %. | |
ed1f651b | 391 | %d marks the argument containing or following the %d as a |
ee618c17 | 392 | temporary file name, so that that file will be deleted if GCC exits |
ed1f651b RS |
393 | successfully. Unlike %g, this contributes no text to the argument. |
394 | %w marks the argument containing or following the %w as the | |
395 | "output file" of this compilation. This puts the argument | |
396 | into the sequence of arguments that %o will substitute later. | |
17211ab5 | 397 | %V indicates that this compilation produces no "output file". |
ed1f651b RS |
398 | %W{...} |
399 | like %{...} but mark last argument supplied within | |
400 | as a file to be deleted on failure. | |
401 | %o substitutes the names of all the output files, with spaces | |
402 | automatically placed around them. You should write spaces | |
403 | around the %o as well or the results are undefined. | |
404 | %o is for use in the specs for running the linker. | |
405 | Input files whose names have no recognized suffix are not compiled | |
406 | at all, but they are included among the output files, so they will | |
407 | be linked. | |
dd75c292 | 408 | %O substitutes the suffix for object files. Note that this is |
a1d9074c TT |
409 | handled specially when it immediately follows %g, %u, or %U |
410 | (with or without a suffix argument) because of the need for | |
411 | those to form complete file names. The handling is such that | |
412 | %O is treated exactly as if it had already been substituted, | |
413 | except that %g, %u, and %U do not currently support additional | |
414 | SUFFIX characters following %O as they would following, for | |
415 | example, `.o'. | |
047d636f | 416 | %I Substitute any of -iprefix (made from GCC_EXEC_PREFIX), -isysroot |
2b6dd222 JM |
417 | (made from TARGET_SYSTEM_ROOT), -isystem (made from COMPILER_PATH |
418 | and -B options) and -imultilib as necessary. | |
ed1f651b RS |
419 | %s current argument is the name of a library or startup file of some sort. |
420 | Search for that file in a standard list of directories | |
421 | and substitute the full name found. | |
422 | %eSTR Print STR as an error message. STR is terminated by a newline. | |
423 | Use this when inconsistent options are detected. | |
09da1532 | 424 | %nSTR Print STR as a notice. STR is terminated by a newline. |
ed1f651b RS |
425 | %x{OPTION} Accumulate an option for %X. |
426 | %X Output the accumulated linker options specified by compilations. | |
c9ebacb8 | 427 | %Y Output the accumulated assembler options specified by compilations. |
57cb9b60 | 428 | %Z Output the accumulated preprocessor options specified by compilations. |
ed1f651b RS |
429 | %a process ASM_SPEC as a spec. |
430 | This allows config.h to specify part of the spec for running as. | |
431 | %A process ASM_FINAL_SPEC as a spec. A capital A is actually | |
432 | used here. This can be used to run a post-processor after the | |
9ec36da5 | 433 | assembler has done its job. |
48ff801b | 434 | %D Dump out a -L option for each directory in startfile_prefixes. |
60103a34 | 435 | If multilib_dir is set, extra entries are generated with it affixed. |
ed1f651b RS |
436 | %l process LINK_SPEC as a spec. |
437 | %L process LIB_SPEC as a spec. | |
68d69835 | 438 | %G process LIBGCC_SPEC as a spec. |
380e5ca4 MM |
439 | %R Output the concatenation of target_system_root and |
440 | target_sysroot_suffix. | |
ed1f651b RS |
441 | %S process STARTFILE_SPEC as a spec. A capital S is actually used here. |
442 | %E process ENDFILE_SPEC as a spec. A capital E is actually used here. | |
9db0819e | 443 | %C process CPP_SPEC as a spec. |
ed1f651b RS |
444 | %1 process CC1_SPEC as a spec. |
445 | %2 process CC1PLUS_SPEC as a spec. | |
446 | %* substitute the variable part of a matched option. (See below.) | |
447 | Note that each comma in the substituted string is replaced by | |
448 | a single space. | |
4977bab6 ZW |
449 | %<S remove all occurrences of -S from the command line. |
450 | Note - this command is position dependent. % commands in the | |
451 | spec string before this one will see -S, % commands in the | |
452 | spec string after this one will not. | |
453 | %<S* remove all occurrences of all switches beginning with -S from the | |
454 | command line. | |
f3226a90 JT |
455 | %:function(args) |
456 | Call the named function FUNCTION, passing it ARGS. ARGS is | |
457 | first processed as a nested spec string, then split into an | |
458 | argument vector in the usual fashion. The function returns | |
459 | a string which is processed as if it had appeared literally | |
460 | as part of the current spec. | |
ee618c17 | 461 | %{S} substitutes the -S switch, if that switch was given to GCC. |
ed1f651b RS |
462 | If that switch was not specified, this substitutes nothing. |
463 | Here S is a metasyntactic variable. | |
ee618c17 | 464 | %{S*} substitutes all the switches specified to GCC whose names start |
196a37f4 | 465 | with -S. This is used for -o, -I, etc; switches that take |
ee618c17 | 466 | arguments. GCC considers `-o foo' as being one switch whose |
ed1f651b RS |
467 | name starts with `o'. %{o*} would substitute this text, |
468 | including the space; thus, two arguments would be generated. | |
196a37f4 | 469 | %{S*&T*} likewise, but preserve order of S and T options (the order |
1d088dee AJ |
470 | of S and T in the spec is not significant). Can be any number |
471 | of ampersand-separated variables; for each the wild card is | |
472 | optional. Useful for CPP as %{D*&U*&A*}. | |
4977bab6 | 473 | |
ee618c17 BE |
474 | %{S:X} substitutes X, if the -S switch was given to GCC. |
475 | %{!S:X} substitutes X, if the -S switch was NOT given to GCC. | |
4977bab6 | 476 | %{S*:X} substitutes X if one or more switches whose names start |
ee618c17 | 477 | with -S was given to GCC. Normally X is substituted only |
4977bab6 ZW |
478 | once, no matter how many such switches appeared. However, |
479 | if %* appears somewhere in X, then X will be substituted | |
480 | once for each matching switch, with the %* replaced by the | |
481 | part of that switch that matched the '*'. | |
482 | %{.S:X} substitutes X, if processing a file with suffix S. | |
483 | %{!.S:X} substitutes X, if NOT processing a file with suffix S. | |
48137d59 GK |
484 | %{,S:X} substitutes X, if processing a file which will use spec S. |
485 | %{!,S:X} substitutes X, if NOT processing a file which will use spec S. | |
3beb864c | 486 | |
ee618c17 | 487 | %{S|T:X} substitutes X if either -S or -T was given to GCC. This may be |
48137d59 GK |
488 | combined with '!', '.', ',', and '*' as above binding stronger |
489 | than the OR. | |
4977bab6 ZW |
490 | If %* appears in X, all of the alternatives must be starred, and |
491 | only the first matching alternative is substituted. | |
ee618c17 BE |
492 | %{S:X; if S was given to GCC, substitutes X; |
493 | T:Y; else if T was given to GCC, substitutes Y; | |
4977bab6 | 494 | :D} else substitutes D. There can be as many clauses as you need. |
48137d59 | 495 | This may be combined with '.', '!', ',', '|', and '*' as above. |
4977bab6 | 496 | |
b3865ca9 | 497 | %(Spec) processes a specification defined in a specs file as *Spec: |
4089dfab | 498 | %[Spec] as above, but put __ around -D arguments |
ed1f651b | 499 | |
4977bab6 | 500 | The conditional text X in a %{S:X} or similar construct may contain |
ed1f651b | 501 | other nested % constructs or spaces, or even newlines. They are |
4977bab6 ZW |
502 | processed as usual, as described above. Trailing white space in X is |
503 | ignored. White space may also appear anywhere on the left side of the | |
504 | colon in these constructs, except between . or * and the corresponding | |
505 | word. | |
ed1f651b | 506 | |
6c396fb5 | 507 | The -O, -f, -m, and -W switches are handled specifically in these |
f5b0eb4e RK |
508 | constructs. If another value of -O or the negated form of a -f, -m, or |
509 | -W switch is found later in the command line, the earlier switch | |
6c396fb5 RK |
510 | value is ignored, except with {S*} where S is just one letter; this |
511 | passes all matching options. | |
f5b0eb4e | 512 | |
9bf09437 RH |
513 | The character | at the beginning of the predicate text is used to indicate |
514 | that a command should be piped to the following command, but only if -pipe | |
515 | is specified. | |
ed1f651b | 516 | |
ee618c17 | 517 | Note that it is built into GCC which switches take arguments and which |
ed1f651b RS |
518 | do not. You might think it would be useful to generalize this to |
519 | allow each compiler's spec to say which switches take arguments. But | |
ee618c17 | 520 | this cannot be done in a consistent fashion. GCC cannot even decide |
ed1f651b RS |
521 | which input files have been specified without knowing which switches |
522 | take arguments, and it must know which input files to compile in order | |
523 | to tell which compilers to run. | |
524 | ||
ee618c17 | 525 | GCC also knows implicitly that arguments starting in `-l' are to be |
ed1f651b RS |
526 | treated as compiler output files, and passed to the linker in their |
527 | proper position among the other output files. */ | |
