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". */ | |

278 | /* Specs are strings containing lines, each of which (if not blank) | |
279 | is made up of a program name, and arguments separated by spaces. | |
280 | The program name must be exact and start from root, since no path | |
281 | is searched and it is unreliable to depend on the current working directory. | |
282 | Redirection of input or output is not supported; the subprograms must | |
283 | accept filenames saying what files to read and write. | |
284 | ||
285 | In addition, the specs can contain %-sequences to substitute variable text | |
286 | or for conditional text. Here is a table of all defined %-sequences. | |
287 | Note that spaces are not generated automatically around the results of | |
288 | expanding these sequences; therefore, you can concatenate them together | |
289 | or with constant text in a single argument. | |
290 | ||
291 | %% substitute one % into the program name or argument. | |
292 | %i substitute the name of the input file being processed. | |
293 | %b substitute the basename of the input file being processed. | |
294 | This is the substring up to (and not including) the last period | |
295 | and not including the directory. | |
296 | %g substitute the temporary-file-name-base. This is a string chosen | |
297 | once per compilation. Different temporary file names are made by | |
298 | concatenation of constant strings on the end, as in `%g.s'. | |
299 | %g also has the same effect of %d. | |
d887e808 | 300 | %u like %g, but make the temporary file name unique. |
4401b31c | 301 | %U returns the last file name generated with %u. |
ed1f651b RS |
302 | %d marks the argument containing or following the %d as a |
303 | temporary file name, so that that file will be deleted if CC exits | |
304 | successfully. Unlike %g, this contributes no text to the argument. | |
305 | %w marks the argument containing or following the %w as the | |
306 | "output file" of this compilation. This puts the argument | |
307 | into the sequence of arguments that %o will substitute later. | |
308 | %W{...} | |
309 | like %{...} but mark last argument supplied within | |
310 | as a file to be deleted on failure. | |
311 | %o substitutes the names of all the output files, with spaces | |
312 | automatically placed around them. You should write spaces | |
313 | around the %o as well or the results are undefined. | |
314 | %o is for use in the specs for running the linker. | |
315 | Input files whose names have no recognized suffix are not compiled | |
316 | at all, but they are included among the output files, so they will | |
317 | be linked. | |
ed7dae04 | 318 | %O substitutes the suffix for object files. |
ed1f651b RS |
319 | %p substitutes the standard macro predefinitions for the |
320 | current target machine. Use this when running cpp. | |
321 | %P like %p, but puts `__' before and after the name of each macro. | |
322 | (Except macros that already have __.) | |
323 | This is for ANSI C. | |
8eebb258 | 324 | %I Substitute a -iprefix option made from GCC_EXEC_PREFIX. |
ed1f651b RS |
325 | %s current argument is the name of a library or startup file of some sort. |
326 | Search for that file in a standard list of directories | |
327 | and substitute the full name found. | |
328 | %eSTR Print STR as an error message. STR is terminated by a newline. | |
329 | Use this when inconsistent options are detected. | |
330 | %x{OPTION} Accumulate an option for %X. | |
331 | %X Output the accumulated linker options specified by compilations. | |
c9ebacb8 | 332 | %Y Output the accumulated assembler options specified by compilations. |
57cb9b60 | 333 | %Z Output the accumulated preprocessor options specified by compilations. |
500c9e81 RS |
334 | %v1 Substitute the major version number of GCC. |
335 | (For version 2.5.n, this is 2.) | |
336 | %v2 Substitute the minor version number of GCC. | |
829407e1 | 337 | (For version 2.5.n, this is 5.) |
ed1f651b RS |
338 | %a process ASM_SPEC as a spec. |
339 | This allows config.h to specify part of the spec for running as. | |
340 | %A process ASM_FINAL_SPEC as a spec. A capital A is actually | |
341 | used here. This can be used to run a post-processor after the | |
342 | assembler has done it's job. | |
48ff801b | 343 | %D Dump out a -L option for each directory in startfile_prefixes. |
60103a34 | 344 | If multilib_dir is set, extra entries are generated with it affixed. |
ed1f651b RS |
345 | %l process LINK_SPEC as a spec. |
346 | %L process LIB_SPEC as a spec. | |
68d69835 | 347 | %G process LIBGCC_SPEC as a spec. |
ed1f651b RS |
348 | %S process STARTFILE_SPEC as a spec. A capital S is actually used here. |
349 | %E process ENDFILE_SPEC as a spec. A capital E is actually used here. | |
350 | %c process SIGNED_CHAR_SPEC as a spec. | |
351 | %C process CPP_SPEC as a spec. A capital C is actually used here. | |
352 | %1 process CC1_SPEC as a spec. | |
353 | %2 process CC1PLUS_SPEC as a spec. | |
a99bf70c | 354 | %| output "-" if the input for the current command is coming from a pipe. |
ed1f651b RS |
355 | %* substitute the variable part of a matched option. (See below.) |
356 | Note that each comma in the substituted string is replaced by | |
357 | a single space. | |
358 | %{S} substitutes the -S switch, if that switch was given to CC. | |
359 | If that switch was not specified, this substitutes nothing. | |
360 | Here S is a metasyntactic variable. | |
361 | %{S*} substitutes all the switches specified to CC whose names start | |
362 | with -S. This is used for -o, -D, -I, etc; switches that take | |
363 | arguments. CC considers `-o foo' as being one switch whose | |
364 | name starts with `o'. %{o*} would substitute this text, | |
365 | including the space; thus, two arguments would be generated. | |
9f3c45fd | 366 | %{^S*} likewise, but don't put a blank between a switch and any args. |
b9490a6e | 367 | %{S*:X} substitutes X if one or more switches whose names start with -S are |
ed1f651b RS |
368 | specified to CC. Note that the tail part of the -S option |
369 | (i.e. the part matched by the `*') will be substituted for each | |
6dc42e49 | 370 | occurrence of %* within X. |
ed1f651b RS |
371 | %{S:X} substitutes X, but only if the -S switch was given to CC. |
372 | %{!S:X} substitutes X, but only if the -S switch was NOT given to CC. | |
373 | %{|S:X} like %{S:X}, but if no S switch, substitute `-'. | |
374 | %{|!S:X} like %{!S:X}, but if there is an S switch, substitute `-'. | |
375 | %{.S:X} substitutes X, but only if processing a file with suffix S. | |
376 | %{!.S:X} substitutes X, but only if NOT processing a file with suffix S. | |
b3865ca9 RS |
377 | %(Spec) processes a specification defined in a specs file as *Spec: |
378 | %[Spec] as above, but put __ around -D arguments | |
ed1f651b RS |
379 | |
380 | The conditional text X in a %{S:X} or %{!S:X} construct may contain | |
381 | other nested % constructs or spaces, or even newlines. They are | |
382 | processed as usual, as described above. | |
383 | ||
6c396fb5 | 384 | The -O, -f, -m, and -W switches are handled specifically in these |
f5b0eb4e RK |
385 | constructs. If another value of -O or the negated form of a -f, -m, or |
386 | -W switch is found later in the command line, the earlier switch | |
6c396fb5 RK |
387 | value is ignored, except with {S*} where S is just one letter; this |
388 | passes all matching options. | |
f5b0eb4e | 389 | |
ed1f651b RS |
390 | The character | is used to indicate that a command should be piped to |
391 | the following command, but only if -pipe is specified. | |
392 | ||
393 | Note that it is built into CC which switches take arguments and which | |
394 | do not. You might think it would be useful to generalize this to | |
395 | allow each compiler's spec to say which switches take arguments. But | |
396 | this cannot be done in a consistent fashion. CC cannot even decide | |
