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

271 | /* Specs are strings containing lines, each of which (if not blank) | |
272 | is made up of a program name, and arguments separated by spaces. | |
273 | The program name must be exact and start from root, since no path | |
274 | is searched and it is unreliable to depend on the current working directory. | |
275 | Redirection of input or output is not supported; the subprograms must | |
276 | accept filenames saying what files to read and write. | |
277 | ||
278 | In addition, the specs can contain %-sequences to substitute variable text | |
279 | or for conditional text. Here is a table of all defined %-sequences. | |
280 | Note that spaces are not generated automatically around the results of | |
281 | expanding these sequences; therefore, you can concatenate them together | |
282 | or with constant text in a single argument. | |
283 | ||
284 | %% substitute one % into the program name or argument. | |
285 | %i substitute the name of the input file being processed. | |
286 | %b substitute the basename of the input file being processed. | |
287 | This is the substring up to (and not including) the last period | |
288 | and not including the directory. | |
289 | %g substitute the temporary-file-name-base. This is a string chosen | |
290 | once per compilation. Different temporary file names are made by | |
291 | concatenation of constant strings on the end, as in `%g.s'. | |
292 | %g also has the same effect of %d. | |
d887e808 | 293 | %u like %g, but make the temporary file name unique. |
4401b31c | 294 | %U returns the last file name generated with %u. |
ed1f651b RS |
295 | %d marks the argument containing or following the %d as a |
296 | temporary file name, so that that file will be deleted if CC exits | |
297 | successfully. Unlike %g, this contributes no text to the argument. | |
298 | %w marks the argument containing or following the %w as the | |
299 | "output file" of this compilation. This puts the argument | |
300 | into the sequence of arguments that %o will substitute later. | |
301 | %W{...} | |
302 | like %{...} but mark last argument supplied within | |
303 | as a file to be deleted on failure. | |
304 | %o substitutes the names of all the output files, with spaces | |
305 | automatically placed around them. You should write spaces | |
306 | around the %o as well or the results are undefined. | |
307 | %o is for use in the specs for running the linker. | |
308 | Input files whose names have no recognized suffix are not compiled | |
309 | at all, but they are included among the output files, so they will | |
310 | be linked. | |
ed7dae04 | 311 | %O substitutes the suffix for object files. |
ed1f651b RS |
312 | %p substitutes the standard macro predefinitions for the |
313 | current target machine. Use this when running cpp. | |
314 | %P like %p, but puts `__' before and after the name of each macro. | |
315 | (Except macros that already have __.) | |
316 | This is for ANSI C. | |
8eebb258 | 317 | %I Substitute a -iprefix option made from GCC_EXEC_PREFIX. |
ed1f651b RS |
318 | %s current argument is the name of a library or startup file of some sort. |
319 | Search for that file in a standard list of directories | |
320 | and substitute the full name found. | |
321 | %eSTR Print STR as an error message. STR is terminated by a newline. | |
322 | Use this when inconsistent options are detected. | |
323 | %x{OPTION} Accumulate an option for %X. | |
324 | %X Output the accumulated linker options specified by compilations. | |
c9ebacb8 | 325 | %Y Output the accumulated assembler options specified by compilations. |
57cb9b60 | 326 | %Z Output the accumulated preprocessor options specified by compilations. |
500c9e81 RS |
327 | %v1 Substitute the major version number of GCC. |
328 | (For version 2.5.n, this is 2.) | |
329 | %v2 Substitute the minor version number of GCC. | |
829407e1 | 330 | (For version 2.5.n, this is 5.) |
ed1f651b RS |
331 | %a process ASM_SPEC as a spec. |
332 | This allows config.h to specify part of the spec for running as. | |
333 | %A process ASM_FINAL_SPEC as a spec. A capital A is actually | |
334 | used here. This can be used to run a post-processor after the | |
335 | assembler has done it's job. | |
48ff801b | 336 | %D Dump out a -L option for each directory in startfile_prefixes. |
60103a34 | 337 | If multilib_dir is set, extra entries are generated with it affixed. |
ed1f651b RS |
338 | %l process LINK_SPEC as a spec. |
339 | %L process LIB_SPEC as a spec. | |
68d69835 | 340 | %G process LIBGCC_SPEC as a spec. |
ed1f651b RS |
341 | %S process STARTFILE_SPEC as a spec. A capital S is actually used here. |
342 | %E process ENDFILE_SPEC as a spec. A capital E is actually used here. | |
343 | %c process SIGNED_CHAR_SPEC as a spec. | |
344 | %C process CPP_SPEC as a spec. A capital C is actually used here. | |
345 | %1 process CC1_SPEC as a spec. | |
346 | %2 process CC1PLUS_SPEC as a spec. | |
a99bf70c | 347 | %| output "-" if the input for the current command is coming from a pipe. |
ed1f651b RS |
348 | %* substitute the variable part of a matched option. (See below.) |
349 | Note that each comma in the substituted string is replaced by | |
350 | a single space. | |
351 | %{S} substitutes the -S switch, if that switch was given to CC. | |
352 | If that switch was not specified, this substitutes nothing. | |
353 | Here S is a metasyntactic variable. | |
354 | %{S*} substitutes all the switches specified to CC whose names start | |
355 | with -S. This is used for -o, -D, -I, etc; switches that take | |
356 | arguments. CC considers `-o foo' as being one switch whose | |
357 | name starts with `o'. %{o*} would substitute this text, | |
358 | including the space; thus, two arguments would be generated. | |
b9490a6e | 359 | %{S*:X} substitutes X if one or more switches whose names start with -S are |
ed1f651b RS |
360 | specified to CC. Note that the tail part of the -S option |
361 | (i.e. the part matched by the `*') will be substituted for each | |
6dc42e49 | 362 | occurrence of %* within X. |
ed1f651b RS |
363 | %{S:X} substitutes X, but only if the -S switch was given to CC. |
364 | %{!S:X} substitutes X, but only if the -S switch was NOT given to CC. | |
365 | %{|S:X} like %{S:X}, but if no S switch, substitute `-'. | |
366 | %{|!S:X} like %{!S:X}, but if there is an S switch, substitute `-'. | |
367 | %{.S:X} substitutes X, but only if processing a file with suffix S. | |
368 | %{!.S:X} substitutes X, but only if NOT processing a file with suffix S. | |
b3865ca9 RS |
369 | %(Spec) processes a specification defined in a specs file as *Spec: |
370 | %[Spec] as above, but put __ around -D arguments | |
ed1f651b RS |
371 | |
372 | The conditional text X in a %{S:X} or %{!S:X} construct may contain | |
373 | other nested % constructs or spaces, or even newlines. They are | |
374 | processed as usual, as described above. | |
375 | ||
6c396fb5 | 376 | The -O, -f, -m, and -W switches are handled specifically in these |
f5b0eb4e RK |
377 | constructs. If another value of -O or the negated form of a -f, -m, or |
378 | -W switch is found later in the command line, the earlier switch | |
6c396fb5 RK |
379 | value is ignored, except with {S*} where S is just one letter; this |
380 | passes all matching options. | |
f5b0eb4e | 381 | |
ed1f651b RS |
382 | The character | is used to indicate that a command should be piped to |
383 | the following command, but only if -pipe is specified. | |
384 | ||
385 | Note that it is built into CC which switches take arguments and which | |
386 | do not. You might think it would be useful to generalize this to | |
387 | allow each compiler's spec to say which switches take arguments. But | |
388 | this cannot be done in a consistent fashion. CC cannot even decide | |
389 | which input files have been specified without knowing which switches | |
390 | take arguments, and it must know which input files to compile in order | |
391 | to tell which compilers to run. | |
392 | ||
393 | CC also knows implicitly that arguments starting in `-l' are to be | |
394 | treated as compiler output files, and passed to the linker in their | |
395 | proper position among the other output files. */ | |
