| 452 | /* The Specs Language | |||
| 453 | ||||
| 454 | Specs are strings containing lines, each of which (if not blank) | |||
| 455 | is made up of a program name, and arguments separated by spaces. | |||
| 456 | The program name must be exact and start from root, since no path | |||
| 457 | is searched and it is unreliable to depend on the current working directory. | |||
| 458 | Redirection of input or output is not supported; the subprograms must | |||
| 459 | accept filenames saying what files to read and write. | |||
| 460 | ||||
| 461 | In addition, the specs can contain %-sequences to substitute variable text | |||
| 462 | or for conditional text. Here is a table of all defined %-sequences. | |||
| 463 | Note that spaces are not generated automatically around the results of | |||
| 464 | expanding these sequences; therefore, you can concatenate them together | |||
| 465 | or with constant text in a single argument. | |||
| 466 | ||||
| 467 | %% substitute one % into the program name or argument. | |||
| 468 | %" substitute an empty argument. | |||
| 469 | %i substitute the name of the input file being processed. | |||
| 470 | %b substitute the basename for outputs related with the input file | |||
| 471 | being processed. This is often a substring of the input file name, | |||
| 472 | up to (and not including) the last period but, unless %w is active, | |||
| 473 | it is affected by the directory selected by -save-temps=*, by | |||
| 474 | -dumpdir, and, in case of multiple compilations, even by -dumpbase | |||
| 475 | and -dumpbase-ext and, in case of linking, by the linker output | |||
| 476 | name. When %w is active, it derives the main output name only from | |||
| 477 | the input file base name; when it is not, it names aux/dump output | |||
| 478 | file. | |||
| 479 | %B same as %b, but include the input file suffix (text after the last | |||
| 480 | period). | |||
| 481 | %gSUFFIX | |||
| 482 | substitute a file name that has suffix SUFFIX and is chosen | |||
| 483 | once per compilation, and mark the argument a la %d. To reduce | |||
| 484 | exposure to denial-of-service attacks, the file name is now | |||
| 485 | chosen in a way that is hard to predict even when previously | |||
| 486 | chosen file names are known. For example, `%g.s ... %g.o ... %g.s' | |||
| 487 | might turn into `ccUVUUAU.s ccXYAXZ12.o ccUVUUAU.s'. SUFFIX matches | |||
| 488 | the regexp "[.0-9A-Za-z]*%O"; "%O" is treated exactly as if it | |||
| 489 | had been pre-processed. Previously, %g was simply substituted | |||
| 490 | with a file name chosen once per compilation, without regard | |||
| 491 | to any appended suffix (which was therefore treated just like | |||
| 492 | ordinary text), making such attacks more likely to succeed. | |||
| 493 | %|SUFFIX | |||
| 494 | like %g, but if -pipe is in effect, expands simply to "-". | |||
| 495 | %mSUFFIX | |||
| 496 | like %g, but if -pipe is in effect, expands to nothing. (We have both | |||
| 497 | %| and %m to accommodate differences between system assemblers; see | |||
| 498 | the AS_NEEDS_DASH_FOR_PIPED_INPUT target macro.) | |||
| 499 | %uSUFFIX | |||
| 500 | like %g, but generates a new temporary file name even if %uSUFFIX | |||
| 501 | was already seen. | |||
| 502 | %USUFFIX | |||
| 503 | substitutes the last file name generated with %uSUFFIX, generating a | |||
| 504 | new one if there is no such last file name. In the absence of any | |||
| 505 | %uSUFFIX, this is just like %gSUFFIX, except they don't share | |||
| 506 | the same suffix "space", so `%g.s ... %U.s ... %g.s ... %U.s' | |||
| 507 | would involve the generation of two distinct file names, one | |||
| 508 | for each `%g.s' and another for each `%U.s'. Previously, %U was | |||
| 509 | simply substituted with a file name chosen for the previous %u, | |||
| 510 | without regard to any appended suffix. | |||
| 511 | %jSUFFIX | |||
| 512 | substitutes the name of the HOST_BIT_BUCKET, if any, and if it is | |||
| 513 | writable, and if save-temps is off; otherwise, substitute the name | |||
| 514 | of a temporary file, just like %u. This temporary file is not | |||
| 515 | meant for communication between processes, but rather as a junk | |||
| 516 | disposal mechanism. | |||
| 517 | %.SUFFIX | |||
| 518 | substitutes .SUFFIX for the suffixes of a matched switch's args when | |||
| 519 | it is subsequently output with %*. SUFFIX is terminated by the next | |||
| 520 | space or %. | |||
| 521 | %d marks the argument containing or following the %d as a | |||
| 522 | temporary file name, so that file will be deleted if GCC exits | |||
| 523 | successfully. Unlike %g, this contributes no text to the argument. | |||
| 524 | %w marks the argument containing or following the %w as the | |||
| 525 | "output file" of this compilation. This puts the argument | |||
| 526 | into the sequence of arguments that %o will substitute later. | |||
| 527 | %V indicates that this compilation produces no "output file". | |||
| 528 | %W{...} | |||
| 529 | like %{...} but marks the last argument supplied within as a file | |||
| 530 | to be deleted on failure. | |||
| 531 | %@{...} | |||
| 532 | like %{...} but puts the result into a FILE and substitutes @FILE | |||
| 533 | if an @file argument has been supplied. | |||
| 534 | %o substitutes the names of all the output files, with spaces | |||
| 535 | automatically placed around them. You should write spaces | |||
| 536 | around the %o as well or the results are undefined. | |||
| 537 | %o is for use in the specs for running the linker. | |||
| 538 | Input files whose names have no recognized suffix are not compiled | |||
| 539 | at all, but they are included among the output files, so they will | |||
| 540 | be linked. | |||
| 541 | %O substitutes the suffix for object files. Note that this is | |||
| 542 | handled specially when it immediately follows %g, %u, or %U | |||
| 543 | (with or without a suffix argument) because of the need for | |||
| 544 | those to form complete file names. The handling is such that | |||
| 545 | %O is treated exactly as if it had already been substituted, | |||
| 546 | except that %g, %u, and %U do not currently support additional | |||
| 547 | SUFFIX characters following %O as they would following, for | |||
| 548 | example, `.o'. | |||
| 549 | %I Substitute any of -iprefix (made from GCC_EXEC_PREFIX), -isysroot | |||
| 550 | (made from TARGET_SYSTEM_ROOT), -isystem (made from COMPILER_PATH | |||
| 551 | and -B options) and -imultilib as necessary. | |||
| 552 | %s current argument is the name of a library or startup file of some sort. | |||
| 553 | Search for that file in a standard list of directories | |||
| 554 | and substitute the full name found. | |||
| 555 | %T current argument is the name of a linker script. | |||
| 556 | Search for that file in the current list of directories to scan for | |||
| 557 | libraries. If the file is located, insert a --script option into the | |||
| 558 | command line followed by the full path name found. If the file is | |||
| 559 | not found then generate an error message. | |||
| 560 | Note: the current working directory is not searched. | |||
| 561 | %eSTR Print STR as an error message. STR is terminated by a newline. | |||
| 562 | Use this when inconsistent options are detected. | |||
| 563 | %nSTR Print STR as a notice. STR is terminated by a newline. | |||
| 564 | %x{OPTION} Accumulate an option for %X. | |||
| 565 | %X Output the accumulated linker options specified by compilations. | |||
| 566 | %Y Output the accumulated assembler options specified by compilations. | |||
| 567 | %Z Output the accumulated preprocessor options specified by compilations. | |||
| 568 | %a process ASM_SPEC as a spec. | |||
| 569 | This allows config.h to specify part of the spec for running as. | |||
| 570 | %A process ASM_FINAL_SPEC as a spec. A capital A is actually | |||
| 571 | used here. This can be used to run a post-processor after the | |||
| 572 | assembler has done its job. | |||
| 573 | %D Dump out a -L option for each directory in startfile_prefixes. | |||
| 574 | If multilib_dir is set, extra entries are generated with it affixed. | |||
| 575 | %l process LINK_SPEC as a spec. | |||
| 576 | %L process LIB_SPEC as a spec. | |||
| 577 | %M Output multilib_os_dir. | |||
| 578 | %G process LIBGCC_SPEC as a spec. | |||
| 579 | %R Output the concatenation of target_system_root and | |||
| 580 | target_sysroot_suffix. | |||
| 581 | %S process STARTFILE_SPEC as a spec. A capital S is actually used here. | |||
| 582 | %E process ENDFILE_SPEC as a spec. A capital E is actually used here. | |||
| 583 | %C process CPP_SPEC as a spec. | |||
| 584 | %1 process CC1_SPEC as a spec. | |||
| 585 | %2 process CC1PLUS_SPEC as a spec. | |||
| 586 | %* substitute the variable part of a matched option. (See below.) | |||
| 587 | Note that each comma in the substituted string is replaced by | |||
| 588 | a single space. A space is appended after the last substition | |||
| 589 | unless there is more text in current sequence. | |||
| 590 | %<S remove all occurrences of -S from the command line. | |||
| 591 | Note - this command is position dependent. % commands in the | |||
| 592 | spec string before this one will see -S, % commands in the | |||
| 593 | spec string after this one will not. | |||
| 594 | %>S Similar to "%<S", but keep it in the GCC command line. | |||
| 595 | %<S* remove all occurrences of all switches beginning with -S from the | |||
| 596 | command line. | |||
| 597 | %:function(args) | |||
| 598 | Call the named function FUNCTION, passing it ARGS. ARGS is | |||
| 599 | first processed as a nested spec string, then split into an | |||
| 600 | argument vector in the usual fashion. The function returns | |||
| 601 | a string which is processed as if it had appeared literally | |||
| 602 | as part of the current spec. | |||
| 603 | %{S} substitutes the -S switch, if that switch was given to GCC. | |||
| 604 | If that switch was not specified, this substitutes nothing. | |||
| 605 | Here S is a metasyntactic variable. | |||
| 606 | %{S*} substitutes all the switches specified to GCC whose names start | |||
| 607 | with -S. This is used for -o, -I, etc; switches that take | |||
| 608 | arguments. GCC considers `-o foo' as being one switch whose | |||
| 609 | name starts with `o'. %{o*} would substitute this text, | |||
| 610 | including the space; thus, two arguments would be generated. | |||
| 611 | %{S*&T*} likewise, but preserve order of S and T options (the order | |||
| 612 | of S and T in the spec is not significant). Can be any number | |||
| 613 | of ampersand-separated variables; for each the wild card is | |||
| 614 | optional. Useful for CPP as %{D*&U*&A*}. | |||
| 615 | ||||
| 616 | %{S:X} substitutes X, if the -S switch was given to GCC. | |||
| 617 | %{!S:X} substitutes X, if the -S switch was NOT given to GCC. | |||
| 618 | %{S*:X} substitutes X if one or more switches whose names start | |||
| 619 | with -S was given to GCC. Normally X is substituted only | |||
| 620 | once, no matter how many such switches appeared. However, | |||
| 621 | if %* appears somewhere in X, then X will be substituted | |||
| 622 | once for each matching switch, with the %* replaced by the | |||
| 623 | part of that switch that matched the '*'. A space will be | |||
| 624 | appended after the last substition unless there is more | |||
| 625 | text in current sequence. | |||
| 626 | %{.S:X} substitutes X, if processing a file with suffix S. | |||
| 627 | %{!.S:X} substitutes X, if NOT processing a file with suffix S. | |||
| 628 | %{,S:X} substitutes X, if processing a file which will use spec S. | |||
| 629 | %{!,S:X} substitutes X, if NOT processing a file which will use spec S. | |||
| 630 | ||||
| 631 | %{S|T:X} substitutes X if either -S or -T was given to GCC. This may be | |||
| 632 | combined with '!', '.', ',', and '*' as above binding stronger | |||
| 633 | than the OR. | |||
| 634 | If %* appears in X, all of the alternatives must be starred, and | |||
| 635 | only the first matching alternative is substituted. | |||
| 636 | %{%:function(args):X} | |||
| 637 | Call function named FUNCTION with args ARGS. If the function | |||
| 638 | returns non-NULL, then X is substituted, if it returns | |||
| 639 | NULL, it isn't substituted. | |||
| 640 | %{S:X; if S was given to GCC, substitutes X; | |||
| 641 | T:Y; else if T was given to GCC, substitutes Y; | |||
| 642 | :D} else substitutes D. There can be as many clauses as you need. | |||
| 643 | This may be combined with '.', '!', ',', '|', and '*' as above. | |||
| 644 | ||||
| 645 | %(Spec) processes a specification defined in a specs file as *Spec: | |||
| 646 | ||||
| 647 | The switch matching text S in a %{S}, %{S:X}, or similar construct can use | |||
| 648 | a backslash to ignore the special meaning of the character following it, | |||
| 649 | thus allowing literal matching of a character that is otherwise specially | |||
| 650 | treated. For example, %{std=iso9899\:1999:X} substitutes X if the | |||
| 651 | -std=iso9899:1999 option is given. | |||
| 652 | ||||
| 653 | The conditional text X in a %{S:X} or similar construct may contain | |||
| 654 | other nested % constructs or spaces, or even newlines. They are | |||
| 655 | processed as usual, as described above. Trailing white space in X is | |||
| 656 | ignored. White space may also appear anywhere on the left side of the | |||
| 657 | colon in these constructs, except between . or * and the corresponding | |||
| 658 | word. | |||
| 659 | ||||
| 660 | The -O, -f, -g, -m, and -W switches are handled specifically in these | |||
| 661 | constructs. If another value of -O or the negated form of a -f, -m, or | |||
| 662 | -W switch is found later in the command line, the earlier switch | |||
| 663 | value is ignored, except with {S*} where S is just one letter; this | |||
| 664 | passes all matching options. | |||
| 665 | ||||
| 666 | The character | at the beginning of the predicate text is used to indicate | |||
| 667 | that a command should be piped to the following command, but only if -pipe | |||
| 668 | is specified. | |||
| 669 | ||||
| 670 | Note that it is built into GCC which switches take arguments and which | |||
| 671 | do not. You might think it would be useful to generalize this to | |||
| 672 | allow each compiler's spec to say which switches take arguments. But | |||
| 673 | this cannot be done in a consistent fashion. GCC cannot even decide | |||
| 674 | which input files have been specified without knowing which switches | |||
| 675 | take arguments, and it must know which input files to compile in order | |||
| 676 | to tell which compilers to run. | |||
| 677 | ||||
| 678 | GCC also knows implicitly that arguments starting in `-l' are to be | |||
| 679 | treated as compiler output files, and passed to the linker in their | |||
| 680 | proper position among the other output files. */ | |||
