| 442 | /* The Specs Language |
| 443 | |
| 444 | Specs are strings containing lines, each of which (if not blank) |
| 445 | is made up of a program name, and arguments separated by spaces. |
| 446 | The program name must be exact and start from root, since no path |
| 447 | is searched and it is unreliable to depend on the current working directory. |
| 448 | Redirection of input or output is not supported; the subprograms must |
| 449 | accept filenames saying what files to read and write. |
| 450 | |
| 451 | In addition, the specs can contain %-sequences to substitute variable text |
| 452 | or for conditional text. Here is a table of all defined %-sequences. |
| 453 | Note that spaces are not generated automatically around the results of |
| 454 | expanding these sequences; therefore, you can concatenate them together |
| 455 | or with constant text in a single argument. |
| 456 | |
| 457 | %% substitute one % into the program name or argument. |
| 458 | %" substitute an empty argument. |
| 459 | %i substitute the name of the input file being processed. |
| 460 | %b substitute the basename for outputs related with the input file |
| 461 | being processed. This is often a substring of the input file name, |
| 462 | up to (and not including) the last period but, unless %w is active, |
| 463 | it is affected by the directory selected by -save-temps=*, by |
| 464 | -dumpdir, and, in case of multiple compilations, even by -dumpbase |
| 465 | and -dumpbase-ext and, in case of linking, by the linker output |
| 466 | name. When %w is active, it derives the main output name only from |
| 467 | the input file base name; when it is not, it names aux/dump output |
| 468 | file. |
| 469 | %B same as %b, but include the input file suffix (text after the last |
| 470 | period). |
| 471 | %gSUFFIX |
| 472 | substitute a file name that has suffix SUFFIX and is chosen |
| 473 | once per compilation, and mark the argument a la %d. To reduce |
| 474 | exposure to denial-of-service attacks, the file name is now |
| 475 | chosen in a way that is hard to predict even when previously |
| 476 | chosen file names are known. For example, `%g.s ... %g.o ... %g.s' |
| 477 | might turn into `ccUVUUAU.s ccXYAXZ12.o ccUVUUAU.s'. SUFFIX matches |
| 478 | the regexp "[.0-9A-Za-z]*%O"; "%O" is treated exactly as if it |
| 479 | had been pre-processed. Previously, %g was simply substituted |
| 480 | with a file name chosen once per compilation, without regard |
| 481 | to any appended suffix (which was therefore treated just like |
| 482 | ordinary text), making such attacks more likely to succeed. |
| 483 | %|SUFFIX |
| 484 | like %g, but if -pipe is in effect, expands simply to "-". |
| 485 | %mSUFFIX |
| 486 | like %g, but if -pipe is in effect, expands to nothing. (We have both |
| 487 | %| and %m to accommodate differences between system assemblers; see |
| 488 | the AS_NEEDS_DASH_FOR_PIPED_INPUT target macro.) |
| 489 | %uSUFFIX |
| 490 | like %g, but generates a new temporary file name even if %uSUFFIX |
| 491 | was already seen. |
| 492 | %USUFFIX |
| 493 | substitutes the last file name generated with %uSUFFIX, generating a |
| 494 | new one if there is no such last file name. In the absence of any |
| 495 | %uSUFFIX, this is just like %gSUFFIX, except they don't share |
| 496 | the same suffix "space", so `%g.s ... %U.s ... %g.s ... %U.s' |
| 497 | would involve the generation of two distinct file names, one |
| 498 | for each `%g.s' and another for each `%U.s'. Previously, %U was |
| 499 | simply substituted with a file name chosen for the previous %u, |
| 500 | without regard to any appended suffix. |
| 501 | %jSUFFIX |
| 502 | substitutes the name of the HOST_BIT_BUCKET, if any, and if it is |
| 503 | writable, and if save-temps is off; otherwise, substitute the name |
| 504 | of a temporary file, just like %u. This temporary file is not |
| 505 | meant for communication between processes, but rather as a junk |
| 506 | disposal mechanism. |
| 507 | %.SUFFIX |
| 508 | substitutes .SUFFIX for the suffixes of a matched switch's args when |
| 509 | it is subsequently output with %*. SUFFIX is terminated by the next |
| 510 | space or %. |
| 511 | %d marks the argument containing or following the %d as a |
| 512 | temporary file name, so that file will be deleted if GCC exits |
| 513 | successfully. Unlike %g, this contributes no text to the argument. |
| 514 | %w marks the argument containing or following the %w as the |
| 515 | "output file" of this compilation. This puts the argument |
| 516 | into the sequence of arguments that %o will substitute later. |
| 517 | %V indicates that this compilation produces no "output file". |
| 518 | %W{...} |
| 519 | like %{...} but marks the last argument supplied within as a file |
| 520 | to be deleted on failure. |
| 521 | %@{...} |
| 522 | like %{...} but puts the result into a FILE and substitutes @FILE |
| 523 | if an @file argument has been supplied. |
| 524 | %o substitutes the names of all the output files, with spaces |
| 525 | automatically placed around them. You should write spaces |
| 526 | around the %o as well or the results are undefined. |
| 527 | %o is for use in the specs for running the linker. |
| 528 | Input files whose names have no recognized suffix are not compiled |
| 529 | at all, but they are included among the output files, so they will |
| 530 | be linked. |
| 531 | %O substitutes the suffix for object files. Note that this is |
| 532 | handled specially when it immediately follows %g, %u, or %U |
| 533 | (with or without a suffix argument) because of the need for |
| 534 | those to form complete file names. The handling is such that |
| 535 | %O is treated exactly as if it had already been substituted, |
| 536 | except that %g, %u, and %U do not currently support additional |
| 537 | SUFFIX characters following %O as they would following, for |
| 538 | example, `.o'. |
| 539 | %I Substitute any of -iprefix (made from GCC_EXEC_PREFIX), -isysroot |
| 540 | (made from TARGET_SYSTEM_ROOT), -isystem (made from COMPILER_PATH |
| 541 | and -B options) and -imultilib as necessary. |
| 542 | %s current argument is the name of a library or startup file of some sort. |
| 543 | Search for that file in a standard list of directories |
| 544 | and substitute the full name found. |
| 545 | %T current argument is the name of a linker script. |
| 546 | Search for that file in the current list of directories to scan for |
| 547 | libraries. If the file is located, insert a --script option into the |
| 548 | command line followed by the full path name found. If the file is |
| 549 | not found then generate an error message. |
| 550 | Note: the current working directory is not searched. |
| 551 | %eSTR Print STR as an error message. STR is terminated by a newline. |
| 552 | Use this when inconsistent options are detected. |
| 553 | %nSTR Print STR as a notice. STR is terminated by a newline. |
| 554 | %x{OPTION} Accumulate an option for %X. |
| 555 | %X Output the accumulated linker options specified by compilations. |
| 556 | %Y Output the accumulated assembler options specified by compilations. |
| 557 | %Z Output the accumulated preprocessor options specified by compilations. |
| 558 | %a process ASM_SPEC as a spec. |
| 559 | This allows config.h to specify part of the spec for running as. |
| 560 | %A process ASM_FINAL_SPEC as a spec. A capital A is actually |
| 561 | used here. This can be used to run a post-processor after the |
| 562 | assembler has done its job. |
| 563 | %D Dump out a -L option for each directory in startfile_prefixes. |
| 564 | If multilib_dir is set, extra entries are generated with it affixed. |
| 565 | %l process LINK_SPEC as a spec. |
| 566 | %L process LIB_SPEC as a spec. |
| 567 | %M Output multilib_os_dir. |
| 568 | %G process LIBGCC_SPEC as a spec. |
| 569 | %R Output the concatenation of target_system_root and |
| 570 | target_sysroot_suffix. |
| 571 | %S process STARTFILE_SPEC as a spec. A capital S is actually used here. |
| 572 | %E process ENDFILE_SPEC as a spec. A capital E is actually used here. |
| 573 | %C process CPP_SPEC as a spec. |
| 574 | %1 process CC1_SPEC as a spec. |
| 575 | %2 process CC1PLUS_SPEC as a spec. |
| 576 | %* substitute the variable part of a matched option. (See below.) |
| 577 | Note that each comma in the substituted string is replaced by |
| 578 | a single space. A space is appended after the last substition |
| 579 | unless there is more text in current sequence. |
| 580 | %<S remove all occurrences of -S from the command line. |
| 581 | Note - this command is position dependent. % commands in the |
| 582 | spec string before this one will see -S, % commands in the |
| 583 | spec string after this one will not. |
| 584 | %>S Similar to "%<S", but keep it in the GCC command line. |
| 585 | %<S* remove all occurrences of all switches beginning with -S from the |
| 586 | command line. |
| 587 | %:function(args) |
| 588 | Call the named function FUNCTION, passing it ARGS. ARGS is |
| 589 | first processed as a nested spec string, then split into an |
| 590 | argument vector in the usual fashion. The function returns |
| 591 | a string which is processed as if it had appeared literally |
| 592 | as part of the current spec. |
| 593 | %{S} substitutes the -S switch, if that switch was given to GCC. |
| 594 | If that switch was not specified, this substitutes nothing. |
| 595 | Here S is a metasyntactic variable. |
| 596 | %{S*} substitutes all the switches specified to GCC whose names start |
| 597 | with -S. This is used for -o, -I, etc; switches that take |
| 598 | arguments. GCC considers `-o foo' as being one switch whose |
| 599 | name starts with `o'. %{o*} would substitute this text, |
| 600 | including the space; thus, two arguments would be generated. |
| 601 | %{S*&T*} likewise, but preserve order of S and T options (the order |
| 602 | of S and T in the spec is not significant). Can be any number |
| 603 | of ampersand-separated variables; for each the wild card is |
| 604 | optional. Useful for CPP as %{D*&U*&A*}. |
| 605 | |
| 606 | %{S:X} substitutes X, if the -S switch was given to GCC. |
| 607 | %{!S:X} substitutes X, if the -S switch was NOT given to GCC. |
| 608 | %{S*:X} substitutes X if one or more switches whose names start |
| 609 | with -S was given to GCC. Normally X is substituted only |
| 610 | once, no matter how many such switches appeared. However, |
| 611 | if %* appears somewhere in X, then X will be substituted |
| 612 | once for each matching switch, with the %* replaced by the |
| 613 | part of that switch that matched the '*'. A space will be |
| 614 | appended after the last substition unless there is more |
| 615 | text in current sequence. |
| 616 | %{.S:X} substitutes X, if processing a file with suffix S. |
| 617 | %{!.S:X} substitutes X, if NOT processing a file with suffix S. |
| 618 | %{,S:X} substitutes X, if processing a file which will use spec S. |
| 619 | %{!,S:X} substitutes X, if NOT processing a file which will use spec S. |
| 620 | |
| 621 | %{S|T:X} substitutes X if either -S or -T was given to GCC. This may be |
| 622 | combined with '!', '.', ',', and '*' as above binding stronger |
| 623 | than the OR. |
| 624 | If %* appears in X, all of the alternatives must be starred, and |
| 625 | only the first matching alternative is substituted. |
| 626 | %{%:function(args):X} |
| 627 | Call function named FUNCTION with args ARGS. If the function |
| 628 | returns non-NULL, then X is substituted, if it returns |
| 629 | NULL, it isn't substituted. |
| 630 | %{S:X; if S was given to GCC, substitutes X; |
| 631 | T:Y; else if T was given to GCC, substitutes Y; |
| 632 | :D} else substitutes D. There can be as many clauses as you need. |
| 633 | This may be combined with '.', '!', ',', '|', and '*' as above. |
| 634 | |
| 635 | %(Spec) processes a specification defined in a specs file as *Spec: |
| 636 | |
| 637 | The switch matching text S in a %{S}, %{S:X}, or similar construct can use |
| 638 | a backslash to ignore the special meaning of the character following it, |
| 639 | thus allowing literal matching of a character that is otherwise specially |
| 640 | treated. For example, %{std=iso9899\:1999:X} substitutes X if the |
| 641 | -std=iso9899:1999 option is given. |
| 642 | |
| 643 | The conditional text X in a %{S:X} or similar construct may contain |
| 644 | other nested % constructs or spaces, or even newlines. They are |
| 645 | processed as usual, as described above. Trailing white space in X is |
| 646 | ignored. White space may also appear anywhere on the left side of the |
| 647 | colon in these constructs, except between . or * and the corresponding |
| 648 | word. |
| 649 | |
| 650 | The -O, -f, -g, -m, and -W switches are handled specifically in these |
| 651 | constructs. If another value of -O or the negated form of a -f, -m, or |
| 652 | -W switch is found later in the command line, the earlier switch |
| 653 | value is ignored, except with {S*} where S is just one letter; this |
| 654 | passes all matching options. |
| 655 | |
| 656 | The character | at the beginning of the predicate text is used to indicate |
| 657 | that a command should be piped to the following command, but only if -pipe |
| 658 | is specified. |
| 659 | |
| 660 | Note that it is built into GCC which switches take arguments and which |
| 661 | do not. You might think it would be useful to generalize this to |
| 662 | allow each compiler's spec to say which switches take arguments. But |
| 663 | this cannot be done in a consistent fashion. GCC cannot even decide |
| 664 | which input files have been specified without knowing which switches |
| 665 | take arguments, and it must know which input files to compile in order |
| 666 | to tell which compilers to run. |
| 667 | |
| 668 | GCC also knows implicitly that arguments starting in `-l' are to be |
| 669 | treated as compiler output files, and passed to the linker in their |
| 670 | proper position among the other output files. */ |

| 4884 | combined with an explicit or implicit dumpdir, whereas when |
| 4885 | linking, a specified or implied link output name (minus |
| 4886 | extension) may be combined with a prevailing -save-temps=* or an |
| 4887 | otherwise implied dumpdir, but not override a prevailing |
| 4888 | -dumpdir. Primary outputs (e.g., linker output when linking |
| 4889 | without -o, or .i, .s or .o outputs when processing multiple |
| 4890 | inputs with -E, -S or -c, respectively) are NOT affected by these |
| 4891 | -save-temps=/-dump* options, always landing in the current |
| 4892 | directory and with the same basename as the input when an output |
| 4893 | name is not given, but when they're intermediate outputs, they |
| 4894 | are named like other aux outputs, so the options affect their |
| 4895 | location and name. |
| 4896 | |
| 4897 | Here are some examples. There are several more in the |
| 4898 | documentation of -o and -dump*, and some quite exhaustive tests |
| 4899 | in gcc.misc-tests/outputs.exp. |
| 4900 | |
| 4901 | When compiling any number of sources, no -dump* nor |
| 4902 | -save-temps=*, all outputs in cwd without prefix: |
| 4903 | |
| 4904 | # gcc -c b.c -gsplit-dwarf |
| 4905 | -> cc1 [-dumpdir ./] -dumpbase b.c -dumpbase-ext .c # b.o b.dwo |
| 4906 | |
| 4907 | # gcc -c b.c d.c -gsplit-dwarf |
| 4908 | -> cc1 [-dumpdir ./] -dumpbase b.c -dumpbase-ext .c # b.o b.dwo |
| 4909 | && cc1 [-dumpdir ./] -dumpbase d.c -dumpbase-ext .c # d.o d.dwo |
| 4910 | |
| 4911 | When compiling and linking, no -dump* nor -save-temps=*, .o |
| 4912 | outputs are temporary, aux outputs land in the dir of the output, |
| 4913 | prefixed with the basename of the linker output: |
| 4914 | |
| 4915 | # gcc b.c d.c -o ab -gsplit-dwarf |
| 4916 | -> cc1 -dumpdir ab- -dumpbase b.c -dumpbase-ext .c # ab-b.dwo |
| 4917 | && cc1 -dumpdir ab- -dumpbase d.c -dumpbase-ext .c # ab-d.dwo |
| 4918 | && link ... -o ab |
| 4919 | |
| 4920 | # gcc b.c d.c [-o a.out] -gsplit-dwarf |
| 4921 | -> cc1 -dumpdir a- -dumpbase b.c -dumpbase-ext .c # a-b.dwo |
| 4922 | && cc1 -dumpdir a- -dumpbase d.c -dumpbase-ext .c # a-d.dwo |
| 4923 | && link ... [-o a.out] |
| 4924 | |
| 4925 | When compiling and linking, a prevailing -dumpdir fully overrides |
| 4926 | the prefix of aux outputs given by the output name: |
| 4927 | |
| 4928 | # gcc -dumpdir f b.c d.c -gsplit-dwarf [-o [dir/]whatever] |
| 4929 | -> cc1 -dumpdir f -dumpbase b.c -dumpbase-ext .c # fb.dwo |
| 4930 | && cc1 -dumpdir f -dumpbase d.c -dumpbase-ext .c # fd.dwo |
| 4931 | && link ... [-o whatever] |
| 4932 | |
| 4933 | When compiling multiple inputs, an explicit -dumpbase is combined |
| 4934 | with -dumpdir, affecting aux outputs, but not the .o outputs: |
| 4935 | |
| 4936 | # gcc -dumpdir f -dumpbase g- b.c d.c -gsplit-dwarf -c |
| 4937 | -> cc1 -dumpdir fg- -dumpbase b.c -dumpbase-ext .c # b.o fg-b.dwo |
| 4938 | && cc1 -dumpdir fg- -dumpbase d.c -dumpbase-ext .c # d.o fg-d.dwo |
| 4939 | |
| 4940 | When compiling and linking with -save-temps, the .o outputs that |
| 4941 | would have been temporary become aux outputs, so they get |
| 4942 | affected by -dump* flags: |
| 4943 | |
| 4944 | # gcc -dumpdir f -dumpbase g- -save-temps b.c d.c |
| 4945 | -> cc1 -dumpdir fg- -dumpbase b.c -dumpbase-ext .c # fg-b.o |
| 4946 | && cc1 -dumpdir fg- -dumpbase d.c -dumpbase-ext .c # fg-d.o |
| 4947 | && link |
| 4948 | |
| 4949 | If -save-temps=* prevails over -dumpdir, however, the explicit |
| 4950 | -dumpdir is discarded, as if it wasn't there. The basename of |
| 4951 | the implicit linker output, a.out or a.exe, becomes a- as the aux |
| 4952 | output prefix for all compilations: |
| 4953 | |
| 4954 | # gcc [-dumpdir f] -save-temps=cwd b.c d.c |
| 4955 | -> cc1 -dumpdir a- -dumpbase b.c -dumpbase-ext .c # a-b.o |
| 4956 | && cc1 -dumpdir a- -dumpbase d.c -dumpbase-ext .c # a-d.o |
| 4957 | && link |
| 4958 | |
| 4959 | A single -dumpbase, applying to multiple inputs, overrides the |
| 4960 | linker output name, implied or explicit, as the aux output prefix: |
| 4961 | |
| 4962 | # gcc [-dumpdir f] -dumpbase g- -save-temps=cwd b.c d.c |
| 4963 | -> cc1 -dumpdir g- -dumpbase b.c -dumpbase-ext .c # g-b.o |
| 4964 | && cc1 -dumpdir g- -dumpbase d.c -dumpbase-ext .c # g-d.o |
| 4965 | && link |
| 4966 | |
| 4967 | # gcc [-dumpdir f] -dumpbase g- -save-temps=cwd b.c d.c -o dir/h.out |
| 4968 | -> cc1 -dumpdir g- -dumpbase b.c -dumpbase-ext .c # g-b.o |
| 4969 | && cc1 -dumpdir g- -dumpbase d.c -dumpbase-ext .c # g-d.o |
| 4970 | && link -o dir/h.out |
| 4971 | |
| 4972 | Now, if the linker output is NOT overridden as a prefix, but |
| 4973 | -save-temps=* overrides implicit or explicit -dumpdir, the |
| 4974 | effective dump dir combines the dir selected by the -save-temps=* |
| 4975 | option with the basename of the specified or implied link output: |
| 4976 | |
| 4977 | # gcc [-dumpdir f] -save-temps=cwd b.c d.c -o dir/h.out |
| 4978 | -> cc1 -dumpdir h- -dumpbase b.c -dumpbase-ext .c # h-b.o |
| 4979 | && cc1 -dumpdir h- -dumpbase d.c -dumpbase-ext .c # h-d.o |
| 4980 | && link -o dir/h.out |
| 4981 | |
| 4982 | # gcc [-dumpdir f] -save-temps=obj b.c d.c -o dir/h.out |
| 4983 | -> cc1 -dumpdir dir/h- -dumpbase b.c -dumpbase-ext .c # dir/h-b.o |
| 4984 | && cc1 -dumpdir dir/h- -dumpbase d.c -dumpbase-ext .c # dir/h-d.o |
| 4985 | && link -o dir/h.out |
| 4986 | |
| 4987 | But then again, a single -dumpbase applying to multiple inputs |
| 4988 | gets used instead of the linker output basename in the combined |
| 4989 | dumpdir: |
| 4990 | |
| 4991 | # gcc [-dumpdir f] -dumpbase g- -save-temps=obj b.c d.c -o dir/h.out |
| 4992 | -> cc1 -dumpdir dir/g- -dumpbase b.c -dumpbase-ext .c # dir/g-b.o |
| 4993 | && cc1 -dumpdir dir/g- -dumpbase d.c -dumpbase-ext .c # dir/g-d.o |
| 4994 | && link -o dir/h.out |
