539 | # There should be an assembly language file named FILE.s in the test |
540 | # suite directory, and a pattern file called FILE.d. `run_dump_test' | |
541 | # will assemble FILE.s, run some tool like `objdump', `objcopy', or | |
542 | # `nm' on the .o file to produce textual output, and then analyze that | |
543 | # with regexps. The FILE.d file specifies what program to run, and | |
544 | # what to expect in its output. | |
545 | # | |
546 | # The FILE.d file begins with zero or more option lines, which specify | |
547 | # flags to pass to the assembler, the program to run to dump the | |
548 | # assembler's output, and the options it wants. The option lines have | |

261def70 | 551 | # # OPTION: VALUE |
3e8cba19 | 552 | # |
261def70 HPN |

554 | # VALUE is OPTION's value. The valid options are described below. | |
555 | # Whitespace is ignored everywhere, except within VALUE. The option | |
556 | # list ends with the first line that doesn't match the above syntax | |
