| 435 | # with regexps. The FILE.d file specifies what program to run, and |
| 436 | # what to expect in its output. |

| 443 | # # OPTION: VALUE |
| 444 | # |
| 445 | # OPTION is the name of some option, like "name" or "objdump", and |

| 447 | # Whitespace is ignored everywhere, except within VALUE. The option |
| 448 | # list ends with the first line that doesn't match the above syntax |
| 449 | # (hmm, not great for error detection). |
| 450 | # |
| 451 | # The optional EXTRA_OPTIONS argument to `run_dump_test' is a list of |
| 452 | # two-element lists. The first element of each is an option name, and |
| 453 | # the second additional arguments to be added on to the end of the |
| 454 | # option list as given in FILE.d. (If omitted, no additional options |
| 455 | # are added.) |
| 456 | # |
| 457 | # The interesting options are: |
| 458 | # |
| 459 | # name: TEST-NAME |
| 460 | # The name of this test, passed to DejaGNU's `pass' and `fail' |
| 461 | # commands. If omitted, this defaults to FILE, the root of the |
| 462 | # .s and .d files' names. |
| 463 | # |
| 464 | # as: FLAGS |
| 465 | # When assembling, pass FLAGS to the assembler. |
| 466 | # If assembling several files, you can pass different assembler |
| 467 | # options in the "source" directives. See below. |

| 473 | # ld_after_inputfiles: FLAGS |
| 474 | # Similar to "ld", but put after all input files. |
| 475 | # |
| 476 | # objcopy_objects: FLAGS |
| 477 | # Run objcopy with the specified flags after assembling any source |
| 478 | # that has the special marker RUN_OBJCOPY in the source specific |
| 479 | # flags. |
| 480 | # |
| 481 | # objcopy_linked_file: FLAGS |
| 482 | # Run objcopy on the linked file with the specified flags. |
| 483 | # This lets you transform the linked file using objcopy, before the |
| 484 | # result is analyzed by an analyzer program specified below (which |
| 485 | # may in turn *also* be objcopy). |
| 486 | # |
| 487 | # PROG: PROGRAM-NAME |
| 488 | # The name of the program to run to analyze the .o file produced |
| 489 | # by the assembler or the linker output. This can be omitted; |
| 490 | # run_dump_test will guess which program to run by seeing which of |
| 491 | # the flags options below is present. |

| 493 | # readelf: FLAGS |
| 494 | # objdump: FLAGS |
| 495 | # nm: FLAGS |
| 496 | # objcopy: FLAGS |
| 497 | # Use the specified program to analyze the assembler or linker |
| 498 | # output file, and pass it FLAGS, in addition to the output name. |
| 499 | # Note that they are run with LC_ALL=C in the environment to give |
| 500 | # consistent sorting of symbols. |
| 501 | # |
| 502 | # source: SOURCE [FLAGS] |
| 503 | # Assemble the file SOURCE.s using the flags in the "as" directive |
| 504 | # and the (optional) FLAGS. If omitted, the source defaults to |
| 505 | # FILE.s. |
| 506 | # This is useful if several .d files want to share a .s file. |
| 507 | # More than one "source" directive can be given, which is useful |
| 508 | # when testing linking. |
| 509 | # |
| 510 | # dump: DUMP |
| 511 | # Match against DUMP.d. If omitted, this defaults to FILE.d. This |
| 512 | # is useful if several .d files differ by options only. Options are |
| 513 | # always read from FILE.d. |
| 514 | # |
| 515 | # xfail: TARGET |
| 516 | # The test is expected to fail on TARGET. This may occur more than |
| 517 | # once. |
| 518 | # |
| 519 | # target: TARGET |
| 520 | # Only run the test for TARGET. This may occur more than once; the |
| 521 | # target being tested must match at least one. You may provide target |
| 522 | # name "cfi" for any target supporting the CFI statements. |
| 523 | # |
| 524 | # notarget: TARGET |
| 525 | # Do not run the test for TARGET. This may occur more than once; |
| 526 | # the target being tested must not match any of them. |
| 527 | # |
| 528 | # error: REGEX |
| 529 | # An error with message matching REGEX must be emitted for the test |
| 530 | # to pass. The PROG, readelf, objdump, nm and objcopy options have |
| 531 | # no meaning and need not be supplied if this is present. Multiple |
| 532 | # "error" directives append to the expected linker error message. |
| 533 | # |
| 534 | # error_output: FILE |
| 535 | # Means the same as 'error', except the regular expression lines |
| 536 | # are contains in FILE. |
| 537 | # |
| 538 | # warning: REGEX |
| 539 | # Expect a linker warning matching REGEX. It is an error to issue |
| 540 | # both "error" and "warning". Multiple "warning" directives |
| 541 | # append to the expected linker warning message. |
| 542 | # |
| 543 | # warning_output: FILE |
| 544 | # Means the same as 'warning', except the regular expression |
| 545 | # lines are contains in FILE. |
| 546 | # |
| 547 | # map: FILE |
| 548 | # Adding this option will cause the linker to generate a linker |
| 549 | # map file, using the -Map=MAPFILE command line option. If |
| 550 | # there is no -Map=MAPFILE in the 'ld: FLAGS' then one will be |
| 551 | # added to the linker command line. The contents of the |
| 552 | # generated MAPFILE are then compared against the regexp lines |
| 553 | # in FILE using `regexp_diff' (see below for details). |
| 554 | # |
| 555 | # Each option may occur at most once unless otherwise mentioned. |
| 556 | # |
| 557 | # After the option lines come regexp lines. `run_dump_test' calls |
| 558 | # `regexp_diff' to compare the output of the dumping tool against the |
| 559 | # regexps in FILE.d. `regexp_diff' is defined in binutils-common.exp; |
| 560 | # see further comments there. |
