532 | # There should be an assembly language file named FILE.s in the test |

534 | # will assemble FILE.s, run some tool like `objdump', `objcopy', or | |
535 | # `nm' on the .o file to produce textual output, and then analyze that | |
536 | # with regexps. The FILE.d file specifies what program to run, and | |
537 | # what to expect in its output. | |
538 | # | |
539 | # The FILE.d file begins with zero or more option lines, which specify | |

541 | # assembler's output, and the options it wants. The option lines have | |

261def70 | 544 | # # OPTION: VALUE |
3e8cba19 | 545 | # |
261def70 HPN |

548 | # Whitespace is ignored everywhere, except within VALUE. The option | |
549 | # list ends with the first line that doesn't match the above syntax | |
