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

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

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

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