444 | # There should be an assembly language file named FILE.s in the test |
445 | # suite directory, and a pattern file called FILE.d. `run_dump_test' | |
446 | # will assemble FILE.s, run some tool like `objdump', `objcopy', or | |
447 | # `nm' on the .o file to produce textual output, and then analyze that | |
448 | # with regexps. The FILE.d file specifies what program to run, and | |
449 | # what to expect in its output. | |
450 | # | |
451 | # The FILE.d file begins with zero or more option lines, which specify | |
452 | # flags to pass to the assembler, the program to run to dump the | |
453 | # assembler's output, and the options it wants. The option lines have | |
454 | # the syntax: | |

261def70 | 456 | # # OPTION: VALUE |
3e8cba19 | 457 | # |
261def70 HPN |
458 | # OPTION is the name of some option, like "name" or "objdump", and |
459 | # VALUE is OPTION's value. The valid options are described below. | |
460 | # Whitespace is ignored everywhere, except within VALUE. The option | |
461 | # list ends with the first line that doesn't match the above syntax | |
462 | # (hmm, not great for error detection). | |

467 | # option list as given in FILE.d. (If omitted, no additional options | |
468 | # are added.) | |
