| 481 | # run_dump_test FILE (optional:) EXTRA_OPTIONS | |
| 482 | # | |
| 483 | # Assemble a .s file, then run some utility on it and check the output. | |
| 484 | # | |
| 485 | # There should be an assembly language file named FILE.s in the test | |
| 486 | # suite directory, and a pattern file called FILE.d. run_dump_test | |
| 487 | # will assemble FILE.s, optionally run objcopy on the object file, | |
| 488 | # optionally run ld, optionally run another objcopy, optionally run | |
| 489 | # another tool under test specified by PROG, then run a dump tool like | |
| 490 | # addr2line, nm, objdump, readelf or size on the object file to produce | |
| 491 | # textual output, and then analyze that with regexps. | |
| 492 | # The FILE.d file specifies what program to run, and what to expect in | |
| 493 | # its output. | |
| 494 | # | |
| 495 | # The FILE.d file begins with zero or more option lines, which specify | |
| 496 | # flags to pass to the assembler, the program to run to dump the | |
| 497 | # assembler's output, and the options it wants. The option lines have | |
| 498 | # the syntax: | |
| 499 | # | |
| 500 | # # OPTION: VALUE | |
| 501 | # | |
| 502 | # OPTION is the name of some option, like "name" or "objdump", and | |
| 503 | # VALUE is OPTION's value. The valid options are described below. | |
| 504 | # Whitespace is ignored everywhere, except within VALUE. The option | |
| 505 | # list ends with the first line that doesn't match the above syntax. | |
| 506 | # However, a line within the options that begins with a #, but doesn't | |
| 507 | # have a recognizable option name followed by a colon, is considered a | |
| 508 | # comment and entirely ignored. | |
| 509 | # | |
| 510 | # The optional EXTRA_OPTIONS argument to `run_dump_test' is a list of | |
| 511 | # two-element lists. The first element of each is an option name, and | |
| 512 | # the second additional arguments to be added on to the end of the | |
| 513 | # option list as given in FILE.d. (If omitted, no additional options | |
| 514 | # are added.) | |
| 515 | # | |
| 516 | # The interesting options are: | |
| 517 | # | |
| 518 | # name: TEST-NAME | |
| 519 | # The name of this test, passed to DejaGNU's `pass' and `fail' | |
| 520 | # commands. If omitted, this defaults to FILE, the root of the | |
| 521 | # .s and .d files' names. | |
| 522 | # | |
| 523 | # as: FLAGS | |
| 524 | # When assembling, pass FLAGS to the assembler. | |
| 525 | # If assembling several files, you can pass different assembler | |
| 526 | # options in the "source" directives. See below. | |
| 52d6f3ee MM |
527 | # Multiple instances of this directive tells run_dump_test to run the test |
| 528 | # multiple times -- one time with each set of flags provided. | |
| 529 | # Each instance will run exactly as a file with a single "as" line, it is | |
| 530 | # not possible to condition any behaviour on which set of "as" flags is | |
| 531 | # used. That means that the "source" specific options are appended to | |
| 532 | # the "as" flags for their corresponding files, and any extra processing | |
| 533 | # (e.g. with "ld" and "objcopy") is repeated for each test. | |
| 8ffb70eb AM |
534 | # |
| 535 | # ld: FLAGS | |
| 536 | # Link assembled files using FLAGS, in the order of the "source" | |
| 537 | # directives, when using multiple files. | |
| 538 | # | |
| 539 | # ld_after_inputfiles: FLAGS | |
| 540 | # Similar to "ld", but put FLAGS after all input files. | |
| 541 | # | |
| 542 | # objcopy_objects: FLAGS | |
| 543 | # Run objcopy with the specified flags after assembling any source | |
| 544 | # that has the special marker RUN_OBJCOPY in the source specific | |
| 545 | # flags. | |
| 546 | # | |
| 547 | # objcopy_linked_file: FLAGS | |
| 548 | # Run objcopy on the linked file with the specified flags. | |
| 549 | # This lets you transform the linked file using objcopy, before the | |
| 550 | # result is analyzed by an analyzer program specified below. | |
| 551 | # | |
| 552 | # PROG: PROGRAM-NAME | |
| 553 | # The name of a program under test, to run to modify or analyze the | |
| 554 | # .o file produced by the assembler. Recognised names are: ar, | |
| 555 | # elfedit, nm, objcopy, ranlib, strings, and strip. | |
| 556 | # | |
| 557 | # DUMPPROG: PROGRAM-NAME | |
| 558 | # The name of the program to run to analyze the file produced | |
| 559 | # by the assembler or the linker. This can be omitted; | |
| 560 | # run_dump_test will guess which program to run from which of | |
| 561 | # the flags options below is present. | |
| 562 | # | |
| 563 | # addr2line: FLAGS | |
| 564 | # nm: FLAGS | |
| 565 | # objdump: FLAGS | |
| 566 | # readelf: FLAGS | |
| 567 | # size: FLAGS | |
| 568 | # Use the specified program to analyze the output file, and pass it | |
| 569 | # FLAGS, in addition to the output name. Note that they are run | |
| 570 | # with LC_ALL=C in the environment to give consistent sorting of | |
| 571 | # symbols. If no FLAGS are needed then you can use: | |
| 572 | # DUMPPROG: [nm objdump readelf addr2line] | |
| 573 | # instead, or just pass a flag that happens to be the default. | |
| 574 | # If objdump is the dump tool and we're not dumping binary, nor | |
| 575 | # have run ld, then the standard section names (.text, .data and | |
| 576 | # .bss) are replaced by target ones if any (eg. rx-elf uses "P" | |
| 577 | # instead of .text). The substition is done for both the | |
| 578 | # objdump options (eg: "-j .text" is replaced by "-j P") and the | |
| 579 | # reference file. | |
| 580 | # | |
| 581 | # source: SOURCE [FLAGS] | |
| 582 | # Assemble the file SOURCE.s using the flags in the "as" directive | |
| 583 | # and the (optional) FLAGS. If omitted, the source defaults to | |
| 584 | # FILE.s. | |
| 585 | # This is useful if several .d files want to share a .s file. | |
| 586 | # More than one "source" directive can be given, which is useful | |
| 587 | # when testing linking. | |
| 588 | # | |
| 589 | # dump: DUMP | |
| 590 | # Match against DUMP.d. If omitted, this defaults to FILE.d. This | |
| 591 | # is useful if several .d files differ by options only. Options are | |
| 592 | # always read from FILE.d. | |
| 593 | # | |
| 594 | # target: GLOB|PROC ... | |
| 595 | # Run this test only on a specified list of targets. More precisely, | |
| 596 | # in the space-separated list each glob is passed to "istarget" and | |
| 597 | # each proc is called as a TCL procedure. List items are interpreted | |
| 598 | # such that procs are denoted by surrounding square brackets, and any | |
| 599 | # other items are consired globs. If the call evaluates true for any | |
| 600 | # of them, the test will be run, otherwise it will be marked | |
| 601 | # unsupported. | |
| 602 | # | |
| 603 | # notarget: GLOB|PROC ... | |
| 604 | # Do not run this test on a specified list of targets. Again, each | |
| 605 | # glob in the space-separated list is passed to "istarget" and each | |

| 607 | # evaluates *false* for *all* of them. Otherwise it will be marked | |
| 608 | # unsupported. | |
| 609 | # | |
| 610 | # alltargets: GLOB|PROC ... | |

| 621 | # "target" respectively, except that they do nothing at all if the | |
| 622 | # check fails. They should only be used in groups, to construct a | |

| 624 | # or expected output on some targets. (For example, see | |

| 633 | # to pass. The DUMPPROG, addr2line, nm, objdump, readelf and size | |
| 634 | # options have no meaning and need not supplied if this is present. | |
| 635 | # Multiple "error" directives append to the expected error message. | |
| 636 | # | |
| 637 | # error_output: FILE | |
| 638 | # Means the same as 'error', except the regular expression lines | |
| 639 | # are contains in FILE. | |
| 640 | # | |
| 641 | # warning: REGEX | |
| 642 | # Expect a warning matching REGEX. It is an error to issue | |
| 643 | # both "error" and "warning". Multiple "warning" directives | |
| 644 | # append to the expected warning message. | |

| 650 | # map: FILE | |
| 651 | # Adding this option will cause the linker to generate a linker | |
| 652 | # map file, using the -Map=MAPFILE command line option. If | |
| 653 | # there is no -Map=MAPFILE in the 'ld: FLAGS' then one will be | |
