403 | # will assemble FILE.s, run some tool like `objdump', `objcopy', or | |

405 | # with regexps. The FILE.d file specifies what program to run, and | |
406 | # what to expect in its output. | |
407 | # | |
408 | # The FILE.d file begins with zero or more option lines, which specify | |
409 | # flags to pass to the assembler, the program to run to dump the | |
410 | # assembler's output, and the options it wants. The option lines have | |
411 | # the syntax: | |
412 | # | |
413 | # # OPTION: VALUE | |
414 | # | |
415 | # OPTION is the name of some option, like "name" or "objdump", and | |
416 | # VALUE is OPTION's value. The valid options are described below. | |
417 | # Whitespace is ignored everywhere, except within VALUE. The option | |
418 | # list ends with the first line that doesn't match the above syntax | |
419 | # (hmm, not great for error detection). | |
420 | # | |
421 | # The interesting options are: | |
422 | # | |
423 | # name: TEST-NAME | |
424 | # The name of this test, passed to DejaGNU's `pass' and `fail' | |
425 | # commands. If omitted, this defaults to FILE, the root of the | |
426 | # .s and .d files' names. | |
427 | # | |
428 | # as: FLAGS | |
429 | # When assembling, pass FLAGS to the assembler. | |

431 | # options in the "source" directives. See below. | |
