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". */ | |

252 | /* Specs are strings containing lines, each of which (if not blank) | |
253 | is made up of a program name, and arguments separated by spaces. | |
254 | The program name must be exact and start from root, since no path | |
255 | is searched and it is unreliable to depend on the current working directory. | |
256 | Redirection of input or output is not supported; the subprograms must | |
257 | accept filenames saying what files to read and write. | |
258 | ||
259 | In addition, the specs can contain %-sequences to substitute variable text | |
260 | or for conditional text. Here is a table of all defined %-sequences. | |
261 | Note that spaces are not generated automatically around the results of | |
262 | expanding these sequences; therefore, you can concatenate them together | |
263 | or with constant text in a single argument. | |
264 | ||
265 | %% substitute one % into the program name or argument. | |
266 | %i substitute the name of the input file being processed. | |
267 | %b substitute the basename of the input file being processed. | |
268 | This is the substring up to (and not including) the last period | |
269 | and not including the directory. | |
dd75c292 CB |
270 | %gSUFFIX |
271 | substitute a file name that has suffix SUFFIX and is chosen | |
272 | once per compilation, and mark the argument a la %d. To reduce | |
273 | exposure to denial-of-service attacks, the file name is now | |
274 | chosen in a way that is hard to predict even when previously | |
275 | chosen file names are known. For example, `%g.s ... %g.o ... %g.s' | |
276 | might turn into `ccUVUUAU.s ccXYAXZ12.o ccUVUUAU.s'. SUFFIX matches | |
a1d9074c TT |
277 | the regexp "[.A-Za-z]*%O"; "%O" is treated exactly as if it |
278 | had been pre-processed. Previously, %g was simply substituted | |
279 | with a file name chosen once per compilation, without regard | |
280 | to any appended suffix (which was therefore treated just like | |
281 | ordinary text), making such attacks more likely to succeed. | |
dd75c292 CB |
282 | %uSUFFIX |
283 | like %g, but generates a new temporary file name even if %uSUFFIX | |
284 | was already seen. | |
285 | %USUFFIX | |
286 | substitutes the last file name generated with %uSUFFIX, generating a | |
287 | new one if there is no such last file name. In the absence of any | |
288 | %uSUFFIX, this is just like %gSUFFIX, except they don't share | |
289 | the same suffix "space", so `%g.s ... %U.s ... %g.s ... %U.s' | |
290 | would involve the generation of two distinct file names, one | |
291 | for each `%g.s' and another for each `%U.s'. Previously, %U was | |
292 | simply substituted with a file name chosen for the previous %u, | |
293 | without regard to any appended suffix. | |
ed1f651b RS |
294 | %d marks the argument containing or following the %d as a |
295 | temporary file name, so that that file will be deleted if CC exits | |
296 | successfully. Unlike %g, this contributes no text to the argument. | |
297 | %w marks the argument containing or following the %w as the | |
298 | "output file" of this compilation. This puts the argument | |
299 | into the sequence of arguments that %o will substitute later. | |
300 | %W{...} | |
301 | like %{...} but mark last argument supplied within | |
302 | as a file to be deleted on failure. | |
303 | %o substitutes the names of all the output files, with spaces | |
304 | automatically placed around them. You should write spaces | |
305 | around the %o as well or the results are undefined. | |
306 | %o is for use in the specs for running the linker. | |
307 | Input files whose names have no recognized suffix are not compiled | |
308 | at all, but they are included among the output files, so they will | |
309 | be linked. | |
dd75c292 | 310 | %O substitutes the suffix for object files. Note that this is |
a1d9074c TT |
311 | handled specially when it immediately follows %g, %u, or %U |
312 | (with or without a suffix argument) because of the need for | |
313 | those to form complete file names. The handling is such that | |
314 | %O is treated exactly as if it had already been substituted, | |
315 | except that %g, %u, and %U do not currently support additional | |
316 | SUFFIX characters following %O as they would following, for | |
317 | example, `.o'. | |
ed1f651b RS |
318 | %p substitutes the standard macro predefinitions for the |
319 | current target machine. Use this when running cpp. | |
320 | %P like %p, but puts `__' before and after the name of each macro. | |
321 | (Except macros that already have __.) | |
322 | This is for ANSI C. | |
8eebb258 | 323 | %I Substitute a -iprefix option made from GCC_EXEC_PREFIX. |
ed1f651b RS |
324 | %s current argument is the name of a library or startup file of some sort. |
325 | Search for that file in a standard list of directories | |
326 | and substitute the full name found. | |
327 | %eSTR Print STR as an error message. STR is terminated by a newline. | |
328 | Use this when inconsistent options are detected. | |
329 | %x{OPTION} Accumulate an option for %X. | |
330 | %X Output the accumulated linker options specified by compilations. | |
c9ebacb8 | 331 | %Y Output the accumulated assembler options specified by compilations. |
57cb9b60 | 332 | %Z Output the accumulated preprocessor options specified by compilations. |
500c9e81 | 333 | %v1 Substitute the major version number of GCC. |
3ea8083f | 334 | (For version 2.5.3, this is 2.) |
500c9e81 | 335 | %v2 Substitute the minor version number of GCC. |
3ea8083f JL |
336 | (For version 2.5.3, this is 5.) |
337 | %v3 Substitute the patch level number of GCC. | |
338 | (For version 2.5.3, this is 3.) | |
ed1f651b RS |
339 | %a process ASM_SPEC as a spec. |
340 | This allows config.h to specify part of the spec for running as. | |
341 | %A process ASM_FINAL_SPEC as a spec. A capital A is actually | |
342 | used here. This can be used to run a post-processor after the | |
9ec36da5 | 343 | assembler has done its job. |
48ff801b | 344 | %D Dump out a -L option for each directory in startfile_prefixes. |
60103a34 | 345 | If multilib_dir is set, extra entries are generated with it affixed. |

346 | %l process LINK_SPEC as a spec. |

68d69835 | 348 | %G process LIBGCC_SPEC as a spec. |

353 | %1 process CC1_SPEC as a spec. | |
354 | %2 process CC1PLUS_SPEC as a spec. | |
a99bf70c | 355 | %| output "-" if the input for the current command is coming from a pipe. |
ed1f651b RS |
356 | %* substitute the variable part of a matched option. (See below.) |
357 | Note that each comma in the substituted string is replaced by | |
358 | a single space. | |
359 | %{S} substitutes the -S switch, if that switch was given to CC. | |
360 | If that switch was not specified, this substitutes nothing. | |
361 | Here S is a metasyntactic variable. | |
362 | %{S*} substitutes all the switches specified to CC whose names start | |
363 | with -S. This is used for -o, -D, -I, etc; switches that take | |
364 | arguments. CC considers `-o foo' as being one switch whose | |
365 | name starts with `o'. %{o*} would substitute this text, | |
366 | including the space; thus, two arguments would be generated. | |
9f3c45fd | 367 | %{^S*} likewise, but don't put a blank between a switch and any args. |
b9490a6e | 368 | %{S*:X} substitutes X if one or more switches whose names start with -S are |
ed1f651b RS |
369 | specified to CC. Note that the tail part of the -S option |
370 | (i.e. the part matched by the `*') will be substituted for each | |
6dc42e49 | 371 | occurrence of %* within X. |
8097c429 TT |
372 | %{<S} remove all occurences of S from the command line. |
373 | Note - this option is position dependent. % commands in the | |
374 | spec string before this option will see S, % commands in the | |
375 | spec string after this option will not. | |
ed1f651b RS |
376 | %{S:X} substitutes X, but only if the -S switch was given to CC. |
377 | %{!S:X} substitutes X, but only if the -S switch was NOT given to CC. | |
378 | %{|S:X} like %{S:X}, but if no S switch, substitute `-'. | |

383 | combined with ! and . as above binding stronger than the OR. | |
b3865ca9 | 384 | %(Spec) processes a specification defined in a specs file as *Spec: |
4089dfab | 385 | %[Spec] as above, but put __ around -D arguments |
ed1f651b RS |
386 | |
387 | The conditional text X in a %{S:X} or %{!S:X} construct may contain | |
388 | other nested % constructs or spaces, or even newlines. They are | |
389 | processed as usual, as described above. | |

6c396fb5 | 391 | The -O, -f, -m, and -W switches are handled specifically in these |
f5b0eb4e RK |
392 | constructs. If another value of -O or the negated form of a -f, -m, or |
393 | -W switch is found later in the command line, the earlier switch | |
6c396fb5 RK |
394 | value is ignored, except with {S*} where S is just one letter; this |
395 | passes all matching options. | |

397 | The character | at the beginning of the predicate text is used to indicate |
398 | that a command should be piped to the following command, but only if -pipe | |
399 | is specified. | |
ed1f651b RS |
400 | |
401 | Note that it is built into CC which switches take arguments and which | |
402 | do not. You might think it would be useful to generalize this to | |
403 | allow each compiler's spec to say which switches take arguments. But | |
404 | this cannot be done in a consistent fashion. CC cannot even decide | |
405 | which input files have been specified without knowing which switches | |
406 | take arguments, and it must know which input files to compile in order | |
407 | to tell which compilers to run. | |
408 | ||
409 | CC also knows implicitly that arguments starting in `-l' are to be | |
410 | treated as compiler output files, and passed to the linker in their | |
411 | proper position among the other output files. */ | |
