454 | # There should be an assembly language file named FILE.s in the test |
455 | # suite directory, and a pattern file called FILE.d. `run_dump_test' | |
456 | # will assemble FILE.s, run some tool like `objdump', `objcopy', or | |
457 | # `nm' on the .o file to produce textual output, and then analyze that | |
458 | # with regexps. The FILE.d file specifies what program to run, and | |
459 | # what to expect in its output. | |
460 | # | |
461 | # The FILE.d file begins with zero or more option lines, which specify | |
462 | # flags to pass to the assembler, the program to run to dump the | |
463 | # assembler's output, and the options it wants. The option lines have | |
