24 | other compilers. It is used because compilation is a complicated procedure | |
25 | which involves running several programs and passing temporary files between | |
26 | them, forwarding the users switches to those programs selectively, | |
27 | and deleting the temporary files at the end. | |
28 | ||
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". */ | |

233 | /* Specs are strings containing lines, each of which (if not blank) | |
234 | is made up of a program name, and arguments separated by spaces. | |
235 | The program name must be exact and start from root, since no path | |
236 | is searched and it is unreliable to depend on the current working directory. | |
237 | Redirection of input or output is not supported; the subprograms must | |
238 | accept filenames saying what files to read and write. | |
239 | ||
240 | In addition, the specs can contain %-sequences to substitute variable text | |
241 | or for conditional text. Here is a table of all defined %-sequences. | |
242 | Note that spaces are not generated automatically around the results of | |
243 | expanding these sequences; therefore, you can concatenate them together | |
244 | or with constant text in a single argument. | |
245 | ||
246 | %% substitute one % into the program name or argument. | |
247 | %i substitute the name of the input file being processed. | |
248 | %b substitute the basename of the input file being processed. | |
249 | This is the substring up to (and not including) the last period | |
250 | and not including the directory. | |
251 | %g substitute the temporary-file-name-base. This is a string chosen | |
252 | once per compilation. Different temporary file names are made by | |
253 | concatenation of constant strings on the end, as in `%g.s'. | |
254 | %g also has the same effect of %d. | |
d887e808 | 255 | %u like %g, but make the temporary file name unique. |
4401b31c | 256 | %U returns the last file name generated with %u. |
ed1f651b RS |
257 | %d marks the argument containing or following the %d as a |
258 | temporary file name, so that that file will be deleted if CC exits | |
259 | successfully. Unlike %g, this contributes no text to the argument. | |
260 | %w marks the argument containing or following the %w as the | |
261 | "output file" of this compilation. This puts the argument | |
262 | into the sequence of arguments that %o will substitute later. | |
263 | %W{...} | |
264 | like %{...} but mark last argument supplied within | |
265 | as a file to be deleted on failure. | |
266 | %o substitutes the names of all the output files, with spaces | |
267 | automatically placed around them. You should write spaces | |
268 | around the %o as well or the results are undefined. | |
269 | %o is for use in the specs for running the linker. | |
270 | Input files whose names have no recognized suffix are not compiled | |
271 | at all, but they are included among the output files, so they will | |
272 | be linked. | |
273 | %p substitutes the standard macro predefinitions for the | |
274 | current target machine. Use this when running cpp. | |
275 | %P like %p, but puts `__' before and after the name of each macro. | |
276 | (Except macros that already have __.) | |
277 | This is for ANSI C. | |
8eebb258 | 278 | %I Substitute a -iprefix option made from GCC_EXEC_PREFIX. |
ed1f651b RS |
279 | %s current argument is the name of a library or startup file of some sort. |
280 | Search for that file in a standard list of directories | |
281 | and substitute the full name found. | |
282 | %eSTR Print STR as an error message. STR is terminated by a newline. | |
283 | Use this when inconsistent options are detected. | |
284 | %x{OPTION} Accumulate an option for %X. | |
285 | %X Output the accumulated linker options specified by compilations. | |
c9ebacb8 | 286 | %Y Output the accumulated assembler options specified by compilations. |
500c9e81 RS |
287 | %v1 Substitute the major version number of GCC. |
288 | (For version 2.5.n, this is 2.) | |
289 | %v2 Substitute the minor version number of GCC. | |
829407e1 | 290 | (For version 2.5.n, this is 5.) |
ed1f651b RS |
291 | %a process ASM_SPEC as a spec. |
292 | This allows config.h to specify part of the spec for running as. | |
293 | %A process ASM_FINAL_SPEC as a spec. A capital A is actually | |
294 | used here. This can be used to run a post-processor after the | |
295 | assembler has done it's job. | |
8cacec76 | 296 | %D Dump out a -L option for each directory in startfile_prefix. |
ed1f651b RS |
297 | %l process LINK_SPEC as a spec. |
298 | %L process LIB_SPEC as a spec. | |
299 | %S process STARTFILE_SPEC as a spec. A capital S is actually used here. | |
300 | %E process ENDFILE_SPEC as a spec. A capital E is actually used here. | |
301 | %c process SIGNED_CHAR_SPEC as a spec. | |
302 | %C process CPP_SPEC as a spec. A capital C is actually used here. | |
303 | %1 process CC1_SPEC as a spec. | |
304 | %2 process CC1PLUS_SPEC as a spec. | |
a99bf70c | 305 | %| output "-" if the input for the current command is coming from a pipe. |
ed1f651b RS |
306 | %* substitute the variable part of a matched option. (See below.) |
307 | Note that each comma in the substituted string is replaced by | |
308 | a single space. | |
309 | %{S} substitutes the -S switch, if that switch was given to CC. | |
310 | If that switch was not specified, this substitutes nothing. | |
311 | Here S is a metasyntactic variable. | |
312 | %{S*} substitutes all the switches specified to CC whose names start | |
313 | with -S. This is used for -o, -D, -I, etc; switches that take | |
314 | arguments. CC considers `-o foo' as being one switch whose | |
315 | name starts with `o'. %{o*} would substitute this text, | |
316 | including the space; thus, two arguments would be generated. | |
b9490a6e | 317 | %{S*:X} substitutes X if one or more switches whose names start with -S are |
ed1f651b RS |
318 | specified to CC. Note that the tail part of the -S option |
319 | (i.e. the part matched by the `*') will be substituted for each | |
6dc42e49 | 320 | occurrence of %* within X. |
ed1f651b RS |
321 | %{S:X} substitutes X, but only if the -S switch was given to CC. |
322 | %{!S:X} substitutes X, but only if the -S switch was NOT given to CC. | |
323 | %{|S:X} like %{S:X}, but if no S switch, substitute `-'. | |
324 | %{|!S:X} like %{!S:X}, but if there is an S switch, substitute `-'. | |
325 | %{.S:X} substitutes X, but only if processing a file with suffix S. | |
326 | %{!.S:X} substitutes X, but only if NOT processing a file with suffix S. | |
b3865ca9 RS |
327 | %(Spec) processes a specification defined in a specs file as *Spec: |
328 | %[Spec] as above, but put __ around -D arguments | |
ed1f651b RS |
329 | |
330 | The conditional text X in a %{S:X} or %{!S:X} construct may contain | |
331 | other nested % constructs or spaces, or even newlines. They are | |
332 | processed as usual, as described above. | |
333 | ||
f5b0eb4e RK |
334 | The -O, -f, -m, and -w switches are handled specifically in these |
335 | constructs. If another value of -O or the negated form of a -f, -m, or | |
336 | -W switch is found later in the command line, the earlier switch | |
337 | value is ignored. | |
338 | ||
ed1f651b RS |
339 | The character | is used to indicate that a command should be piped to |
340 | the following command, but only if -pipe is specified. | |
341 | ||
342 | Note that it is built into CC which switches take arguments and which | |
343 | do not. You might think it would be useful to generalize this to | |
344 | allow each compiler's spec to say which switches take arguments. But | |
345 | this cannot be done in a consistent fashion. CC cannot even decide | |
346 | which input files have been specified without knowing which switches | |
347 | take arguments, and it must know which input files to compile in order | |
348 | to tell which compilers to run. | |
349 | ||
350 | CC also knows implicitly that arguments starting in `-l' are to be | |
351 | treated as compiler output files, and passed to the linker in their | |
352 | proper position among the other output files. */ | |
