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

261def70 | 451 | # # OPTION: VALUE |
3e8cba19 | 452 | # |
261def70 HPN |

454 | # VALUE is OPTION's value. The valid options are described below. | |
455 | # Whitespace is ignored everywhere, except within VALUE. The option | |
456 | # list ends with the first line that doesn't match the above syntax | |
457 | # (hmm, not great for error detection). | |
