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". */ | |

271 | \f |
272 | /* Specs are strings containing lines, each of which (if not blank) | |
273 | is made up of a program name, and arguments separated by spaces. | |
274 | The program name must be exact and start from root, since no path | |
275 | is searched and it is unreliable to depend on the current working directory. | |
276 | Redirection of input or output is not supported; the subprograms must | |
277 | accept filenames saying what files to read and write. | |
278 | ||
279 | In addition, the specs can contain %-sequences to substitute variable text | |
280 | or for conditional text. Here is a table of all defined %-sequences. | |
281 | Note that spaces are not generated automatically around the results of | |
282 | expanding these sequences; therefore, you can concatenate them together | |
283 | or with constant text in a single argument. | |
284 | ||
285 | %% substitute one % into the program name or argument. | |
286 | %i substitute the name of the input file being processed. | |
287 | %b substitute the basename of the input file being processed. | |
288 | This is the substring up to (and not including) the last period | |
289 | and not including the directory. | |
ea414c97 | 290 | %B same as %b, but include the file suffix (text after the last period). |
dd75c292 CB |
291 | %gSUFFIX |
292 | substitute a file name that has suffix SUFFIX and is chosen | |
293 | once per compilation, and mark the argument a la %d. To reduce | |
294 | exposure to denial-of-service attacks, the file name is now | |
295 | chosen in a way that is hard to predict even when previously | |
296 | chosen file names are known. For example, `%g.s ... %g.o ... %g.s' | |
297 | might turn into `ccUVUUAU.s ccXYAXZ12.o ccUVUUAU.s'. SUFFIX matches | |
a1d9074c TT |
298 | the regexp "[.A-Za-z]*%O"; "%O" is treated exactly as if it |
299 | had been pre-processed. Previously, %g was simply substituted | |
300 | with a file name chosen once per compilation, without regard | |
301 | to any appended suffix (which was therefore treated just like | |
302 | ordinary text), making such attacks more likely to succeed. | |
dd75c292 CB |
303 | %uSUFFIX |
304 | like %g, but generates a new temporary file name even if %uSUFFIX | |
305 | was already seen. | |
306 | %USUFFIX | |
307 | substitutes the last file name generated with %uSUFFIX, generating a | |
308 | new one if there is no such last file name. In the absence of any | |
309 | %uSUFFIX, this is just like %gSUFFIX, except they don't share | |
310 | the same suffix "space", so `%g.s ... %U.s ... %g.s ... %U.s' | |
311 | would involve the generation of two distinct file names, one | |
312 | for each `%g.s' and another for each `%U.s'. Previously, %U was | |
313 | simply substituted with a file name chosen for the previous %u, | |
314 | without regard to any appended suffix. | |
49009afd JL |
315 | %jSUFFIX |
316 | substitutes the name of the HOST_BIT_BUCKET, if any, and if it is | |
317 | writable, and if save-temps is off; otherwise, substitute the name | |
318 | of a temporary file, just like %u. This temporary file is not | |
319 | meant for communication between processes, but rather as a junk | |
320 | disposal mechanism. | |
11972f66 NS |
321 | %.SUFFIX |
322 | substitutes .SUFFIX for the suffixes of a matched switch's args when | |
323 | it is subsequently output with %*. SUFFIX is terminated by the next | |
324 | space or %. | |
ed1f651b RS |
325 | %d marks the argument containing or following the %d as a |
326 | temporary file name, so that that file will be deleted if CC exits | |
327 | successfully. Unlike %g, this contributes no text to the argument. | |
328 | %w marks the argument containing or following the %w as the | |
329 | "output file" of this compilation. This puts the argument | |
330 | into the sequence of arguments that %o will substitute later. | |
331 | %W{...} | |
332 | like %{...} but mark last argument supplied within | |
333 | as a file to be deleted on failure. | |
334 | %o substitutes the names of all the output files, with spaces | |
335 | automatically placed around them. You should write spaces | |
336 | around the %o as well or the results are undefined. | |
337 | %o is for use in the specs for running the linker. | |
338 | Input files whose names have no recognized suffix are not compiled | |
339 | at all, but they are included among the output files, so they will | |
340 | be linked. | |
dd75c292 | 341 | %O substitutes the suffix for object files. Note that this is |
a1d9074c TT |
342 | handled specially when it immediately follows %g, %u, or %U |
343 | (with or without a suffix argument) because of the need for | |
344 | those to form complete file names. The handling is such that | |
345 | %O is treated exactly as if it had already been substituted, | |
346 | except that %g, %u, and %U do not currently support additional | |
347 | SUFFIX characters following %O as they would following, for | |
348 | example, `.o'. | |
ed1f651b RS |
349 | %p substitutes the standard macro predefinitions for the |
350 | current target machine. Use this when running cpp. | |
351 | %P like %p, but puts `__' before and after the name of each macro. | |
352 | (Except macros that already have __.) | |
353 | This is for ANSI C. | |
8eebb258 | 354 | %I Substitute a -iprefix option made from GCC_EXEC_PREFIX. |
ed1f651b RS |
355 | %s current argument is the name of a library or startup file of some sort. |
356 | Search for that file in a standard list of directories | |
357 | and substitute the full name found. | |
358 | %eSTR Print STR as an error message. STR is terminated by a newline. | |
359 | Use this when inconsistent options are detected. | |
360 | %x{OPTION} Accumulate an option for %X. | |
361 | %X Output the accumulated linker options specified by compilations. | |
c9ebacb8 | 362 | %Y Output the accumulated assembler options specified by compilations. |
57cb9b60 | 363 | %Z Output the accumulated preprocessor options specified by compilations. |
500c9e81 | 364 | %v1 Substitute the major version number of GCC. |
3ea8083f | 365 | (For version 2.5.3, this is 2.) |
500c9e81 | 366 | %v2 Substitute the minor version number of GCC. |
3ea8083f JL |
367 | (For version 2.5.3, this is 5.) |
368 | %v3 Substitute the patch level number of GCC. | |
369 | (For version 2.5.3, this is 3.) | |

ed1f651b RS |
389 | %* substitute the variable part of a matched option. (See below.) |
390 | Note that each comma in the substituted string is replaced by | |
391 | a single space. | |
392 | %{S} substitutes the -S switch, if that switch was given to CC. | |
393 | If that switch was not specified, this substitutes nothing. | |
394 | Here S is a metasyntactic variable. | |
395 | %{S*} substitutes all the switches specified to CC whose names start | |
196a37f4 | 396 | with -S. This is used for -o, -I, etc; switches that take |
ed1f651b RS |
397 | arguments. CC considers `-o foo' as being one switch whose |
398 | name starts with `o'. %{o*} would substitute this text, | |
399 | including the space; thus, two arguments would be generated. | |
9f3c45fd | 400 | %{^S*} likewise, but don't put a blank between a switch and any args. |
196a37f4 NB |
401 | %{S*&T*} likewise, but preserve order of S and T options (the order |
402 | of S and T in the spec is not significant). Can be any number | |
403 | of ampersand-separated variables; for each the wild card is | |
404 | optional. Useful for CPP as %{D*&U*&A*}. | |
b9490a6e | 405 | %{S*:X} substitutes X if one or more switches whose names start with -S are |
ed1f651b RS |
406 | specified to CC. Note that the tail part of the -S option |
407 | (i.e. the part matched by the `*') will be substituted for each | |
6dc42e49 | 408 | occurrence of %* within X. |
50c57e7b | 409 | %{<S} remove all occurences of -S from the command line. |
8097c429 | 410 | Note - this option is position dependent. % commands in the |
50c57e7b | 411 | spec string before this option will see -S, % commands in the |
8097c429 | 412 | spec string after this option will not. |
ed1f651b RS |
413 | %{S:X} substitutes X, but only if the -S switch was given to CC. |
414 | %{!S:X} substitutes X, but only if the -S switch was NOT given to CC. | |
415 | %{|S:X} like %{S:X}, but if no S switch, substitute `-'. | |
416 | %{|!S:X} like %{!S:X}, but if there is an S switch, substitute `-'. | |
417 | %{.S:X} substitutes X, but only if processing a file with suffix S. | |
418 | %{!.S:X} substitutes X, but only if NOT processing a file with suffix S. | |
9bf09437 RH |
419 | %{S|P:X} substitutes X if either -S or -P was given to CC. This may be |
420 | combined with ! and . as above binding stronger than the OR. | |
b3865ca9 | 421 | %(Spec) processes a specification defined in a specs file as *Spec: |
4089dfab | 422 | %[Spec] as above, but put __ around -D arguments |
ed1f651b RS |
423 | |
424 | The conditional text X in a %{S:X} or %{!S:X} construct may contain | |
425 | other nested % constructs or spaces, or even newlines. They are | |
426 | processed as usual, as described above. | |
427 | ||
6c396fb5 | 428 | The -O, -f, -m, and -W switches are handled specifically in these |
f5b0eb4e RK |
429 | constructs. If another value of -O or the negated form of a -f, -m, or |
430 | -W switch is found later in the command line, the earlier switch | |
6c396fb5 RK |
431 | value is ignored, except with {S*} where S is just one letter; this |
432 | passes all matching options. | |
f5b0eb4e | 433 | |
9bf09437 RH |
434 | The character | at the beginning of the predicate text is used to indicate |
435 | that a command should be piped to the following command, but only if -pipe | |
436 | is specified. | |
ed1f651b RS |
437 | |
438 | Note that it is built into CC which switches take arguments and which | |
439 | do not. You might think it would be useful to generalize this to | |
440 | allow each compiler's spec to say which switches take arguments. But | |
441 | this cannot be done in a consistent fashion. CC cannot even decide | |
442 | which input files have been specified without knowing which switches | |
443 | take arguments, and it must know which input files to compile in order | |
444 | to tell which compilers to run. | |
445 | ||
446 | CC also knows implicitly that arguments starting in `-l' are to be | |
447 | treated as compiler output files, and passed to the linker in their | |
448 | proper position among the other output files. */ | |
