261def70 HPN |
456 | # There should be an assembly language file named FILE.s in the test |
457 | # suite directory, and a pattern file called FILE.d. `run_dump_test' | |
458 | # will assemble FILE.s, run some tool like `objdump', `objcopy', or | |
459 | # `nm' on the .o file to produce textual output, and then analyze that | |
460 | # with regexps. The FILE.d file specifies what program to run, and | |
461 | # what to expect in its output. | |
462 | # | |
463 | # The FILE.d file begins with zero or more option lines, which specify | |
464 | # flags to pass to the assembler, the program to run to dump the | |
465 | # assembler's output, and the options it wants. The option lines have | |
466 | # the syntax: | |
3e8cba19 | 467 | # |
261def70 | 468 | # # OPTION: VALUE |
3e8cba19 | 469 | # |
261def70 HPN |
470 | # OPTION is the name of some option, like "name" or "objdump", and |
471 | # VALUE is OPTION's value. The valid options are described below. | |
472 | # Whitespace is ignored everywhere, except within VALUE. The option | |
473 | # list ends with the first line that doesn't match the above syntax | |
474 | # (hmm, not great for error detection). | |

476 | # The interesting options are: | |
3e8cba19 | 477 | # |
261def70 HPN |
478 | # name: TEST-NAME |
479 | # The name of this test, passed to DejaGNU's `pass' and `fail' | |
480 | # commands. If omitted, this defaults to FILE, the root of the | |
481 | # .s and .d files' names. | |
3e8cba19 | 482 | # |
261def70 HPN |
483 | # as: FLAGS |
484 | # When assembling, pass FLAGS to the assembler. | |
485 | # If assembling several files, you can pass different assembler | |
486 | # options in the "source" directives. See below. | |
487 | # | |
488 | # ld: FLAGS | |

492 | # objcopy_linked_file: FLAGS |
493 | # Run objcopy on the linked file with the specified flags. | |
494 | # This lets you transform the linked file using objcopy, before the | |
495 | # result is analyzed by an analyzer program specified below (which | |
496 | # may in turn *also* be objcopy). | |
497 | # | |
261def70 HPN |
498 | # PROG: PROGRAM-NAME |
499 | # The name of the program to run to analyze the .o file produced | |
500 | # by the assembler or the linker output. This can be omitted; | |
501 | # run_dump_test will guess which program to run by seeing which of | |
502 | # the flags options below is present. | |

512 | # source: SOURCE [FLAGS] | |
513 | # Assemble the file SOURCE.s using the flags in the "as" directive | |
514 | # and the (optional) FLAGS. If omitted, the source defaults to | |
515 | # FILE.s. | |
516 | # This is useful if several .d files want to share a .s file. | |
517 | # More than one "source" directive can be given, which is useful | |
518 | # when testing linking. | |

520 | # xfail: TARGET | |

522 | # once. | |

526 | # target being tested must match at least one. | |
527 | # | |
528 | # notarget: TARGET | |
529 | # Do not run the test for TARGET. This may occur more than once; | |
530 | # the target being tested must not match any of them. | |
531 | # | |
532 | # error: REGEX | |
533 | # An error with message matching REGEX must be emitted for the test | |
534 | # to pass. The PROG, objdump, nm and objcopy options have no | |
535 | # meaning and need not supplied if this is present. | |
536 | # | |
537 | # Each option may occur at most once unless otherwise mentioned. | |
