23 /* This program is the user interface to the C compiler and possibly to

26 them, forwarding the users switches to those programs selectively,
27 and deleting the temporary files at the end.
29 CC recognizes how to compile each input file by suffixes in the file names.
30 Once it knows which kind of compilation to perform, the procedure for
31 compilation is specified by a string called a "spec". */

232 /* Specs are strings containing lines, each of which (if not blank)
233 is made up of a program name, and arguments separated by spaces.
234 The program name must be exact and start from root, since no path
235 is searched and it is unreliable to depend on the current working directory.
236 Redirection of input or output is not supported; the subprograms must
237 accept filenames saying what files to read and write.
239 In addition, the specs can contain %-sequences to substitute variable text
240 or for conditional text. Here is a table of all defined %-sequences.
241 Note that spaces are not generated automatically around the results of
242 expanding these sequences; therefore, you can concatenate them together
243 or with constant text in a single argument.
245 %% substitute one % into the program name or argument.
246 %i substitute the name of the input file being processed.
247 %b substitute the basename of the input file being processed.
248 This is the substring up to (and not including) the last period
249 and not including the directory.
250 %g substitute the temporary-file-name-base. This is a string chosen
251 once per compilation. Different temporary file names are made by
252 concatenation of constant strings on the end, as in `%g.s'.
253 %g also has the same effect of %d.
254 %u like %g, but make the temporary file name unique.
255 %U returns the last file name generated with %u.
256 %d marks the argument containing or following the %d as a
257 temporary file name, so that that file will be deleted if CC exits
258 successfully. Unlike %g, this contributes no text to the argument.
259 %w marks the argument containing or following the %w as the
260 "output file" of this compilation. This puts the argument
261 into the sequence of arguments that %o will substitute later.
263 like %{...} but mark last argument supplied within
264 as a file to be deleted on failure.
265 %o substitutes the names of all the output files, with spaces
266 automatically placed around them. You should write spaces
267 around the %o as well or the results are undefined.
268 %o is for use in the specs for running the linker.
269 Input files whose names have no recognized suffix are not compiled
270 at all, but they are included among the output files, so they will
272 %p substitutes the standard macro predefinitions for the
273 current target machine. Use this when running cpp.
274 %P like %p, but puts `__' before and after the name of each macro.
275 (Except macros that already have __.)
277 %I Substitute a -iprefix option made from GCC_EXEC_PREFIX.
278 %s current argument is the name of a library or startup file of some sort.
279 Search for that file in a standard list of directories
280 and substitute the full name found.
281 %eSTR Print STR as an error message. STR is terminated by a newline.
282 Use this when inconsistent options are detected.
283 %x{OPTION} Accumulate an option for %X.
284 %X Output the accumulated linker options specified by compilations.
285 %Y Output the accumulated assembler options specified by compilations.
286 %v1 Substitute the major version number of GCC.
287 (For version 2.5.n, this is 2.)
288 %v2 Substitute the minor version number of GCC.
289 (For version 2.5.n, this is 5.)
290 %a process ASM_SPEC as a spec.
291 This allows config.h to specify part of the spec for running as.
292 %A process ASM_FINAL_SPEC as a spec. A capital A is actually
293 used here. This can be used to run a post-processor after the
294 assembler has done it's job.
295 %D Dump out a -L option for each directory in startfile_prefix.
296 %l process LINK_SPEC as a spec.
297 %L process LIB_SPEC as a spec.
298 %S process STARTFILE_SPEC as a spec. A capital S is actually used here.
299 %E process ENDFILE_SPEC as a spec. A capital E is actually used here.
300 %c process SIGNED_CHAR_SPEC as a spec.
301 %C process CPP_SPEC as a spec. A capital C is actually used here.
302 %1 process CC1_SPEC as a spec.
303 %2 process CC1PLUS_SPEC as a spec.
304 %| output "-" if the input for the current command is coming from a pipe.
305 %* substitute the variable part of a matched option. (See below.)
306 Note that each comma in the substituted string is replaced by
308 %{S} substitutes the -S switch, if that switch was given to CC.
309 If that switch was not specified, this substitutes nothing.
310 Here S is a metasyntactic variable.
311 %{S*} substitutes all the switches specified to CC whose names start
312 with -S. This is used for -o, -D, -I, etc; switches that take
313 arguments. CC considers `-o foo' as being one switch whose
314 name starts with `o'. %{o*} would substitute this text,
315 including the space; thus, two arguments would be generated.
316 %{S*:X} substitutes X if one or more switches whose names start with -S are
317 specified to CC. Note that the tail part of the -S option
318 (i.e. the part matched by the `*') will be substituted for each
319 occurrence of %* within X.
320 %{S:X} substitutes X, but only if the -S switch was given to CC.
321 %{!S:X} substitutes X, but only if the -S switch was NOT given to CC.
322 %{|S:X} like %{S:X}, but if no S switch, substitute `-'.
323 %{|!S:X} like %{!S:X}, but if there is an S switch, substitute `-'.
324 %{.S:X} substitutes X, but only if processing a file with suffix S.
325 %{!.S:X} substitutes X, but only if NOT processing a file with suffix S.
326 %(Spec) processes a specification defined in a specs file as *Spec:
327 %[Spec] as above, but put __ around -D arguments
329 The conditional text X in a %{S:X} or %{!S:X} construct may contain
330 other nested % constructs or spaces, or even newlines. They are
331 processed as usual, as described above.
333 The character | is used to indicate that a command should be piped to
334 the following command, but only if -pipe is specified.
336 Note that it is built into CC which switches take arguments and which
337 do not. You might think it would be useful to generalize this to
338 allow each compiler's spec to say which switches take arguments. But
339 this cannot be done in a consistent fashion. CC cannot even decide
340 which input files have been specified without knowing which switches
341 take arguments, and it must know which input files to compile in order
342 to tell which compilers to run.
344 CC also knows implicitly that arguments starting in `-l' are to be
345 treated as compiler output files, and passed to the linker in their
346 proper position among the other output files. */
