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

457 | # will assemble FILE.s, run some tool like `objdump', `objcopy', or | |
458 | # `nm' on the .o file to produce textual output, and then analyze that | |
459 | # with regexps. The FILE.d file specifies what program to run, and | |

461 | # | |
462 | # The FILE.d file begins with zero or more option lines, which specify | |
