261def70 HPN |
495 | # There should be an assembly language file named FILE.s in the test |
496 | # suite directory, and a pattern file called FILE.d. `run_dump_test' | |
497 | # will assemble FILE.s, run some tool like `objdump', `objcopy', or | |
498 | # `nm' on the .o file to produce textual output, and then analyze that | |
499 | # with regexps. The FILE.d file specifies what program to run, and | |
500 | # what to expect in its output. | |
501 | # | |
502 | # The FILE.d file begins with zero or more option lines, which specify | |
503 | # flags to pass to the assembler, the program to run to dump the | |
504 | # assembler's output, and the options it wants. The option lines have | |
505 | # the syntax: | |
3e8cba19 | 506 | # |
261def70 | 507 | # # OPTION: VALUE |
3e8cba19 | 508 | # |
261def70 HPN |
509 | # OPTION is the name of some option, like "name" or "objdump", and |
510 | # VALUE is OPTION's value. The valid options are described below. | |
511 | # Whitespace is ignored everywhere, except within VALUE. The option | |
512 | # list ends with the first line that doesn't match the above syntax | |
513 | # (hmm, not great for error detection). | |

520 | # .s and .d files' names. | |
3e8cba19 | 521 | # |
261def70 HPN |
522 | # as: FLAGS |
