542 | # run_dump_test FILE (optional:) EXTRA_OPTIONS | |
543 | # | |
544 | # Assemble a .s file, then run some utility on it and check the output. | |
545 | # | |
546 | # There should be an assembly language file named FILE.s in the test | |
547 | # suite directory, and a pattern file called FILE.d. run_dump_test | |
548 | # will assemble FILE.s, optionally run objcopy on the object file, | |
549 | # optionally run ld, optionally run another objcopy, optionally run | |
550 | # another tool under test specified by PROG, then run a dump tool like | |
551 | # addr2line, nm, objdump, readelf or size on the object file to produce | |
552 | # textual output, and then analyze that with regexps. | |
553 | # The FILE.d file specifies what program to run, and what to expect in | |
554 | # its output. | |
555 | # | |
556 | # The FILE.d file begins with zero or more option lines, which specify | |
557 | # flags to pass to the assembler, the program to run to dump the | |
558 | # assembler's output, and the options it wants. The option lines have | |
559 | # the syntax: | |
560 | # | |
561 | # # OPTION: VALUE | |
562 | # | |
563 | # OPTION is the name of some option, like "name" or "objdump", and | |
564 | # VALUE is OPTION's value. The valid options are described below. | |
565 | # Whitespace is ignored everywhere, except within VALUE. The option | |
566 | # list ends with the first line that doesn't match the above syntax. | |
567 | # However, a line within the options that begins with a #, but doesn't | |
568 | # have a recognizable option name followed by a colon, is considered a | |
569 | # comment and entirely ignored. | |
570 | # | |
571 | # The optional EXTRA_OPTIONS argument to `run_dump_test' is a list of | |
572 | # two-element lists. The first element of each is an option name, and | |
573 | # the second additional arguments to be added on to the end of the | |
574 | # option list as given in FILE.d. (If omitted, no additional options | |
575 | # are added.) | |
576 | # | |
577 | # The interesting options are: | |
578 | # | |
579 | # name: TEST-NAME | |
580 | # The name of this test, passed to DejaGNU's `pass' and `fail' | |
581 | # commands. If omitted, this defaults to FILE, the root of the | |
582 | # .s and .d files' names. | |
583 | # | |
584 | # as: FLAGS | |
585 | # When assembling, pass FLAGS to the assembler. | |
586 | # If assembling several files, you can pass different assembler | |
587 | # options in the "source" directives. See below. | |
52d6f3ee MM |
588 | # Multiple instances of this directive tells run_dump_test to run the test |
589 | # multiple times -- one time with each set of flags provided. | |
590 | # Each instance will run exactly as a file with a single "as" line, it is | |
591 | # not possible to condition any behaviour on which set of "as" flags is | |
592 | # used. That means that the "source" specific options are appended to | |
593 | # the "as" flags for their corresponding files, and any extra processing | |
594 | # (e.g. with "ld" and "objcopy") is repeated for each test. | |
8ffb70eb AM |
595 | # |
596 | # ld: FLAGS | |
597 | # Link assembled files using FLAGS, in the order of the "source" | |
598 | # directives, when using multiple files. | |
599 | # | |
600 | # ld_after_inputfiles: FLAGS | |
601 | # Similar to "ld", but put FLAGS after all input files. | |
602 | # | |
603 | # objcopy_objects: FLAGS | |
604 | # Run objcopy with the specified flags after assembling any source | |
605 | # that has the special marker RUN_OBJCOPY in the source specific | |
606 | # flags. | |
607 | # | |
608 | # objcopy_linked_file: FLAGS | |
609 | # Run objcopy on the linked file with the specified flags. | |
610 | # This lets you transform the linked file using objcopy, before the | |
611 | # result is analyzed by an analyzer program specified below. | |
612 | # | |
613 | # PROG: PROGRAM-NAME | |
614 | # The name of a program under test, to run to modify or analyze the | |
615 | # .o file produced by the assembler. Recognised names are: ar, | |
616 | # elfedit, nm, objcopy, ranlib, strings, and strip. | |
617 | # | |
618 | # DUMPPROG: PROGRAM-NAME | |
619 | # The name of the program to run to analyze the file produced | |
620 | # by the assembler or the linker. This can be omitted; | |
621 | # run_dump_test will guess which program to run from which of | |
622 | # the flags options below is present. | |
623 | # | |
624 | # addr2line: FLAGS | |
625 | # nm: FLAGS | |
626 | # objdump: FLAGS | |
627 | # readelf: FLAGS | |
628 | # size: FLAGS | |
629 | # Use the specified program to analyze the output file, and pass it | |
630 | # FLAGS, in addition to the output name. Note that they are run | |
631 | # with LC_ALL=C in the environment to give consistent sorting of | |
632 | # symbols. If no FLAGS are needed then you can use: | |
633 | # DUMPPROG: [nm objdump readelf addr2line] | |
634 | # instead, or just pass a flag that happens to be the default. | |
635 | # If objdump is the dump tool and we're not dumping binary, nor | |
636 | # have run ld, then the standard section names (.text, .data and | |
637 | # .bss) are replaced by target ones if any (eg. rx-elf uses "P" | |
638 | # instead of .text). The substition is done for both the | |
639 | # objdump options (eg: "-j .text" is replaced by "-j P") and the | |
640 | # reference file. | |
641 | # | |
642 | # source: SOURCE [FLAGS] | |
643 | # Assemble the file SOURCE.s using the flags in the "as" directive | |
644 | # and the (optional) FLAGS. If omitted, the source defaults to | |
645 | # FILE.s. | |
646 | # This is useful if several .d files want to share a .s file. | |
647 | # More than one "source" directive can be given, which is useful | |
648 | # when testing linking. | |
649 | # | |
650 | # dump: DUMP | |
651 | # Match against DUMP.d. If omitted, this defaults to FILE.d. This | |
652 | # is useful if several .d files differ by options only. Options are | |
653 | # always read from FILE.d. | |
654 | # | |
655 | # target: GLOB|PROC ... | |
656 | # Run this test only on a specified list of targets. More precisely, | |
657 | # in the space-separated list each glob is passed to "istarget" and | |
658 | # each proc is called as a TCL procedure. List items are interpreted | |
659 | # such that procs are denoted by surrounding square brackets, and any | |
660 | # other items are consired globs. If the call evaluates true for any | |
661 | # of them, the test will be run, otherwise it will be marked | |
662 | # unsupported. | |
663 | # | |
664 | # notarget: GLOB|PROC ... | |
665 | # Do not run this test on a specified list of targets. Again, each | |
666 | # glob in the space-separated list is passed to "istarget" and each | |
667 | # proc is called as a TCL procedure, and the test is run if it | |
668 | # evaluates *false* for *all* of them. Otherwise it will be marked | |
669 | # unsupported. | |
670 | # | |
671 | # alltargets: GLOB|PROC ... | |

681 | # These are exactly the same as "notarget", "alltargets" and | |
682 | # "target" respectively, except that they do nothing at all if the | |
683 | # check fails. They should only be used in groups, to construct a | |
684 | # single test which is run on all targets but with variant options | |
685 | # or expected output on some targets. (For example, see | |
686 | # gas/arm/inst.d and gas/arm/wince_inst.d.) | |
687 | # | |
688 | # xfail: GLOB|PROC ... | |

690 | # of targets. | |
691 | # | |
692 | # error: REGEX | |
693 | # An error with message matching REGEX must be emitted for the test | |
694 | # to pass. The DUMPPROG, addr2line, nm, objdump, readelf and size | |
695 | # options have no meaning and need not supplied if this is present. | |
696 | # Multiple "error" directives append to the expected error message. | |
697 | # | |
698 | # error_output: FILE | |
699 | # Means the same as 'error', except the regular expression lines | |
700 | # are contains in FILE. | |
701 | # | |
702 | # warning: REGEX | |
703 | # Expect a warning matching REGEX. It is an error to issue | |
704 | # both "error" and "warning". Multiple "warning" directives | |
705 | # append to the expected warning message. | |
706 | # | |
707 | # warning_output: FILE | |
708 | # Means the same as 'warning', except the regular expression | |
709 | # lines are contains in FILE. | |
710 | # | |
711 | # map: FILE | |
712 | # Adding this option will cause the linker to generate a linker | |
713 | # map file, using the -Map=MAPFILE command line option. If | |
714 | # there is no -Map=MAPFILE in the 'ld: FLAGS' then one will be | |
715 | # added to the linker command line. The contents of the | |
716 | # generated MAPFILE are then compared against the regexp lines | |
717 | # in FILE using `regexp_diff' (see below for details). | |
718 | # | |
