28 | and deleting the temporary files at the end. | |

219 | /* Specs are strings containing lines, each of which (if not blank) | |
220 | is made up of a program name, and arguments separated by spaces. | |
221 | The program name must be exact and start from root, since no path | |
222 | is searched and it is unreliable to depend on the current working directory. | |
223 | Redirection of input or output is not supported; the subprograms must | |
224 | accept filenames saying what files to read and write. | |
225 | ||
226 | In addition, the specs can contain %-sequences to substitute variable text | |
227 | or for conditional text. Here is a table of all defined %-sequences. | |
228 | Note that spaces are not generated automatically around the results of | |
229 | expanding these sequences; therefore, you can concatenate them together | |
230 | or with constant text in a single argument. | |
231 | ||
232 | %% substitute one % into the program name or argument. | |
233 | %i substitute the name of the input file being processed. | |
234 | %b substitute the basename of the input file being processed. | |
235 | This is the substring up to (and not including) the last period | |
236 | and not including the directory. | |
dd75c292 CB |
237 | %gSUFFIX |
238 | substitute a file name that has suffix SUFFIX and is chosen | |
239 | once per compilation, and mark the argument a la %d. To reduce | |
240 | exposure to denial-of-service attacks, the file name is now | |
241 | chosen in a way that is hard to predict even when previously | |
242 | chosen file names are known. For example, `%g.s ... %g.o ... %g.s' | |
243 | might turn into `ccUVUUAU.s ccXYAXZ12.o ccUVUUAU.s'. SUFFIX matches | |
244 | the regexp "[.A-Za-z]*" or the special string "%O", which is | |
245 | treated exactly as if %O had been pre-processed. Previously, %g | |
246 | was simply substituted with a file name chosen once per compilation, | |
247 | without regard to any appended suffix (which was therefore treated | |
248 | just like ordinary text), making such attacks more likely to succeed. | |
249 | %uSUFFIX | |
250 | like %g, but generates a new temporary file name even if %uSUFFIX | |
251 | was already seen. | |
252 | %USUFFIX | |
253 | substitutes the last file name generated with %uSUFFIX, generating a | |
254 | new one if there is no such last file name. In the absence of any | |
255 | %uSUFFIX, this is just like %gSUFFIX, except they don't share | |
256 | the same suffix "space", so `%g.s ... %U.s ... %g.s ... %U.s' | |
257 | would involve the generation of two distinct file names, one | |
258 | for each `%g.s' and another for each `%U.s'. Previously, %U was | |
259 | simply substituted with a file name chosen for the previous %u, | |
260 | without regard to any appended suffix. | |
ed1f651b RS |
261 | %d marks the argument containing or following the %d as a |
262 | temporary file name, so that that file will be deleted if CC exits | |
263 | successfully. Unlike %g, this contributes no text to the argument. | |
264 | %w marks the argument containing or following the %w as the | |
265 | "output file" of this compilation. This puts the argument | |
266 | into the sequence of arguments that %o will substitute later. | |
267 | %W{...} | |
268 | like %{...} but mark last argument supplied within | |
269 | as a file to be deleted on failure. | |
270 | %o substitutes the names of all the output files, with spaces | |
271 | automatically placed around them. You should write spaces | |
272 | around the %o as well or the results are undefined. | |
273 | %o is for use in the specs for running the linker. | |
274 | Input files whose names have no recognized suffix are not compiled | |
275 | at all, but they are included among the output files, so they will | |
276 | be linked. | |
dd75c292 CB |
277 | %O substitutes the suffix for object files. Note that this is |
278 | handled specially when it immediately follows %g, %u, or %U, | |
279 | because of the need for those to form complete file names. The | |
280 | handling is such that %O is treated exactly as if it had already | |
281 | been substituted, except that %g, %u, and %U do not currently | |
282 | support additional SUFFIX characters following %O as they would | |
283 | following, for example, `.o'. | |
ed1f651b RS |
284 | %p substitutes the standard macro predefinitions for the |
285 | current target machine. Use this when running cpp. | |
286 | %P like %p, but puts `__' before and after the name of each macro. | |
287 | (Except macros that already have __.) | |
288 | This is for ANSI C. | |
8eebb258 | 289 | %I Substitute a -iprefix option made from GCC_EXEC_PREFIX. |
ed1f651b RS |
290 | %s current argument is the name of a library or startup file of some sort. |
291 | Search for that file in a standard list of directories | |
292 | and substitute the full name found. | |
293 | %eSTR Print STR as an error message. STR is terminated by a newline. | |
294 | Use this when inconsistent options are detected. | |
295 | %x{OPTION} Accumulate an option for %X. | |
296 | %X Output the accumulated linker options specified by compilations. | |
c9ebacb8 | 297 | %Y Output the accumulated assembler options specified by compilations. |
57cb9b60 | 298 | %Z Output the accumulated preprocessor options specified by compilations. |
500c9e81 RS |
299 | %v1 Substitute the major version number of GCC. |
300 | (For version 2.5.n, this is 2.) | |
301 | %v2 Substitute the minor version number of GCC. | |
829407e1 | 302 | (For version 2.5.n, this is 5.) |
ed1f651b RS |
303 | %a process ASM_SPEC as a spec. |
304 | This allows config.h to specify part of the spec for running as. | |

a99bf70c | 319 | %| output "-" if the input for the current command is coming from a pipe. |
ed1f651b RS |
320 | %* substitute the variable part of a matched option. (See below.) |
321 | Note that each comma in the substituted string is replaced by | |
322 | a single space. | |
323 | %{S} substitutes the -S switch, if that switch was given to CC. | |
324 | If that switch was not specified, this substitutes nothing. | |
325 | Here S is a metasyntactic variable. | |
326 | %{S*} substitutes all the switches specified to CC whose names start | |
327 | with -S. This is used for -o, -D, -I, etc; switches that take | |
328 | arguments. CC considers `-o foo' as being one switch whose | |
329 | name starts with `o'. %{o*} would substitute this text, | |
330 | including the space; thus, two arguments would be generated. | |
9f3c45fd | 331 | %{^S*} likewise, but don't put a blank between a switch and any args. |
b9490a6e | 332 | %{S*:X} substitutes X if one or more switches whose names start with -S are |
ed1f651b RS |
333 | specified to CC. Note that the tail part of the -S option |
334 | (i.e. the part matched by the `*') will be substituted for each | |
6dc42e49 | 335 | occurrence of %* within X. |
ed1f651b RS |
336 | %{S:X} substitutes X, but only if the -S switch was given to CC. |
337 | %{!S:X} substitutes X, but only if the -S switch was NOT given to CC. | |
338 | %{|S:X} like %{S:X}, but if no S switch, substitute `-'. | |
339 | %{|!S:X} like %{!S:X}, but if there is an S switch, substitute `-'. | |
340 | %{.S:X} substitutes X, but only if processing a file with suffix S. | |
341 | %{!.S:X} substitutes X, but only if NOT processing a file with suffix S. | |
9bf09437 RH |
342 | %{S|P:X} substitutes X if either -S or -P was given to CC. This may be |
343 | combined with ! and . as above binding stronger than the OR. | |
b3865ca9 | 344 | %(Spec) processes a specification defined in a specs file as *Spec: |
4089dfab | 345 | %[Spec] as above, but put __ around -D arguments |
ed1f651b RS |
346 | |
347 | The conditional text X in a %{S:X} or %{!S:X} construct may contain | |
348 | other nested % constructs or spaces, or even newlines. They are | |
349 | processed as usual, as described above. | |
350 | ||
6c396fb5 | 351 | The -O, -f, -m, and -W switches are handled specifically in these |
f5b0eb4e RK |
352 | constructs. If another value of -O or the negated form of a -f, -m, or |
353 | -W switch is found later in the command line, the earlier switch | |
6c396fb5 RK |
354 | value is ignored, except with {S*} where S is just one letter; this |
355 | passes all matching options. | |
f5b0eb4e | 356 | |
9bf09437 RH |
357 | The character | at the beginning of the predicate text is used to indicate |
358 | that a command should be piped to the following command, but only if -pipe | |
359 | is specified. | |
ed1f651b RS |
360 | |
361 | Note that it is built into CC which switches take arguments and which | |
362 | do not. You might think it would be useful to generalize this to | |
363 | allow each compiler's spec to say which switches take arguments. But | |
364 | this cannot be done in a consistent fashion. CC cannot even decide | |
365 | which input files have been specified without knowing which switches | |
366 | take arguments, and it must know which input files to compile in order | |
367 | to tell which compilers to run. | |
368 | ||
369 | CC also knows implicitly that arguments starting in `-l' are to be | |
370 | treated as compiler output files, and passed to the linker in their | |
371 | proper position among the other output files. */ | |
