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

248 | /* Specs are strings containing lines, each of which (if not blank) | |
249 | is made up of a program name, and arguments separated by spaces. | |
250 | The program name must be exact and start from root, since no path | |
251 | is searched and it is unreliable to depend on the current working directory. | |
252 | Redirection of input or output is not supported; the subprograms must | |
253 | accept filenames saying what files to read and write. | |
254 | ||
255 | In addition, the specs can contain %-sequences to substitute variable text | |
256 | or for conditional text. Here is a table of all defined %-sequences. | |
257 | Note that spaces are not generated automatically around the results of | |
258 | expanding these sequences; therefore, you can concatenate them together | |
259 | or with constant text in a single argument. | |
260 | ||
261 | %% substitute one % into the program name or argument. | |
262 | %i substitute the name of the input file being processed. | |
263 | %b substitute the basename of the input file being processed. | |
264 | This is the substring up to (and not including) the last period | |
265 | and not including the directory. | |
dd75c292 CB |
266 | %gSUFFIX |
267 | substitute a file name that has suffix SUFFIX and is chosen | |
268 | once per compilation, and mark the argument a la %d. To reduce | |
269 | exposure to denial-of-service attacks, the file name is now | |
270 | chosen in a way that is hard to predict even when previously | |
271 | chosen file names are known. For example, `%g.s ... %g.o ... %g.s' | |
272 | might turn into `ccUVUUAU.s ccXYAXZ12.o ccUVUUAU.s'. SUFFIX matches | |
273 | the regexp "[.A-Za-z]*" or the special string "%O", which is | |
274 | treated exactly as if %O had been pre-processed. Previously, %g | |
275 | was simply substituted with a file name chosen once per compilation, | |
276 | without regard to any appended suffix (which was therefore treated | |
277 | just like ordinary text), making such attacks more likely to succeed. | |
278 | %uSUFFIX | |
279 | like %g, but generates a new temporary file name even if %uSUFFIX | |
280 | was already seen. | |
281 | %USUFFIX | |
282 | substitutes the last file name generated with %uSUFFIX, generating a | |
283 | new one if there is no such last file name. In the absence of any | |
284 | %uSUFFIX, this is just like %gSUFFIX, except they don't share | |
285 | the same suffix "space", so `%g.s ... %U.s ... %g.s ... %U.s' | |
286 | would involve the generation of two distinct file names, one | |
287 | for each `%g.s' and another for each `%U.s'. Previously, %U was | |
288 | simply substituted with a file name chosen for the previous %u, | |
289 | without regard to any appended suffix. | |
ed1f651b RS |
290 | %d marks the argument containing or following the %d as a |
291 | temporary file name, so that that file will be deleted if CC exits | |
292 | successfully. Unlike %g, this contributes no text to the argument. | |
293 | %w marks the argument containing or following the %w as the | |
294 | "output file" of this compilation. This puts the argument | |
295 | into the sequence of arguments that %o will substitute later. | |
296 | %W{...} | |
297 | like %{...} but mark last argument supplied within | |
298 | as a file to be deleted on failure. | |
299 | %o substitutes the names of all the output files, with spaces | |
300 | automatically placed around them. You should write spaces | |
301 | around the %o as well or the results are undefined. | |
302 | %o is for use in the specs for running the linker. | |
303 | Input files whose names have no recognized suffix are not compiled | |
304 | at all, but they are included among the output files, so they will | |
305 | be linked. | |
dd75c292 CB |
306 | %O substitutes the suffix for object files. Note that this is |
307 | handled specially when it immediately follows %g, %u, or %U, | |
308 | because of the need for those to form complete file names. The | |
309 | handling is such that %O is treated exactly as if it had already | |
310 | been substituted, except that %g, %u, and %U do not currently | |
311 | support additional SUFFIX characters following %O as they would | |
312 | following, for example, `.o'. | |
ed1f651b RS |
313 | %p substitutes the standard macro predefinitions for the |
314 | current target machine. Use this when running cpp. | |
315 | %P like %p, but puts `__' before and after the name of each macro. | |
316 | (Except macros that already have __.) | |
317 | This is for ANSI C. | |
8eebb258 | 318 | %I Substitute a -iprefix option made from GCC_EXEC_PREFIX. |
ed1f651b RS |
319 | %s current argument is the name of a library or startup file of some sort. |
320 | Search for that file in a standard list of directories | |
321 | and substitute the full name found. | |
322 | %eSTR Print STR as an error message. STR is terminated by a newline. | |
323 | Use this when inconsistent options are detected. | |
324 | %x{OPTION} Accumulate an option for %X. | |
325 | %X Output the accumulated linker options specified by compilations. | |
c9ebacb8 | 326 | %Y Output the accumulated assembler options specified by compilations. |
57cb9b60 | 327 | %Z Output the accumulated preprocessor options specified by compilations. |
500c9e81 RS |
328 | %v1 Substitute the major version number of GCC. |
329 | (For version 2.5.n, this is 2.) | |
330 | %v2 Substitute the minor version number of GCC. | |
829407e1 | 331 | (For version 2.5.n, this is 5.) |
ed1f651b RS |
332 | %a process ASM_SPEC as a spec. |
333 | This allows config.h to specify part of the spec for running as. | |
334 | %A process ASM_FINAL_SPEC as a spec. A capital A is actually | |
335 | used here. This can be used to run a post-processor after the | |
9ec36da5 | 336 | assembler has done its job. |
48ff801b | 337 | %D Dump out a -L option for each directory in startfile_prefixes. |
60103a34 | 338 | If multilib_dir is set, extra entries are generated with it affixed. |

68d69835 | 341 | %G process LIBGCC_SPEC as a spec. |
ed1f651b RS |

343 | %E process ENDFILE_SPEC as a spec. A capital E is actually used here. | |
344 | %c process SIGNED_CHAR_SPEC as a spec. | |
345 | %C process CPP_SPEC as a spec. A capital C is actually used here. | |
346 | %1 process CC1_SPEC as a spec. | |
347 | %2 process CC1PLUS_SPEC as a spec. | |
a99bf70c | 348 | %| output "-" if the input for the current command is coming from a pipe. |
ed1f651b RS |
349 | %* substitute the variable part of a matched option. (See below.) |
350 | Note that each comma in the substituted string is replaced by | |
351 | a single space. | |
352 | %{S} substitutes the -S switch, if that switch was given to CC. | |
353 | If that switch was not specified, this substitutes nothing. | |
354 | Here S is a metasyntactic variable. | |
355 | %{S*} substitutes all the switches specified to CC whose names start | |
356 | with -S. This is used for -o, -D, -I, etc; switches that take | |
357 | arguments. CC considers `-o foo' as being one switch whose | |
358 | name starts with `o'. %{o*} would substitute this text, | |
359 | including the space; thus, two arguments would be generated. | |
9f3c45fd | 360 | %{^S*} likewise, but don't put a blank between a switch and any args. |
b9490a6e | 361 | %{S*:X} substitutes X if one or more switches whose names start with -S are |
ed1f651b RS |
362 | specified to CC. Note that the tail part of the -S option |
363 | (i.e. the part matched by the `*') will be substituted for each | |
6dc42e49 | 364 | occurrence of %* within X. |
ed1f651b RS |
365 | %{S:X} substitutes X, but only if the -S switch was given to CC. |
366 | %{!S:X} substitutes X, but only if the -S switch was NOT given to CC. | |
367 | %{|S:X} like %{S:X}, but if no S switch, substitute `-'. | |
368 | %{|!S:X} like %{!S:X}, but if there is an S switch, substitute `-'. | |
369 | %{.S:X} substitutes X, but only if processing a file with suffix S. | |
370 | %{!.S:X} substitutes X, but only if NOT processing a file with suffix S. | |
9bf09437 RH |
371 | %{S|P:X} substitutes X if either -S or -P was given to CC. This may be |
372 | combined with ! and . as above binding stronger than the OR. | |
b3865ca9 | 373 | %(Spec) processes a specification defined in a specs file as *Spec: |
4089dfab | 374 | %[Spec] as above, but put __ around -D arguments |
ed1f651b RS |
375 | |
376 | The conditional text X in a %{S:X} or %{!S:X} construct may contain | |
377 | other nested % constructs or spaces, or even newlines. They are | |
378 | processed as usual, as described above. | |
379 | ||
6c396fb5 | 380 | The -O, -f, -m, and -W switches are handled specifically in these |
f5b0eb4e RK |
381 | constructs. If another value of -O or the negated form of a -f, -m, or |

393 | this cannot be done in a consistent fashion. CC cannot even decide | |
394 | which input files have been specified without knowing which switches | |

396 | to tell which compilers to run. | |
