| 540 | # Assemble a .s file, then run some utility on it and check the output. |
| 541 | # |
| 542 | # There should be an assembly language file named FILE.s in the test |
| 543 | # suite directory, and a pattern file called FILE.d. `run_dump_test' |
| 544 | # will assemble FILE.s, run some tool like `objdump', `objcopy', or |
| 545 | # `nm' on the .o file to produce textual output, and then analyze that |
| 546 | # with regexps. The FILE.d file specifies what program to run, and |
| 547 | # what to expect in its output. |
| 548 | # |
| 549 | # The FILE.d file begins with zero or more option lines, which specify |
| 550 | # flags to pass to the assembler, the program to run to dump the |
| 551 | # assembler's output, and the options it wants. The option lines have |
| 552 | # the syntax: |
| 553 | # |
| 554 | # # OPTION: VALUE |
| 555 | # |
| 556 | # OPTION is the name of some option, like "name" or "objdump", and |
| 557 | # VALUE is OPTION's value. The valid options are described below. |
| 558 | # Whitespace is ignored everywhere, except within VALUE. The option |
| 559 | # list ends with the first line that doesn't match the above syntax |
| 560 | # (hmm, not great for error detection). |
| 561 | # |
| 562 | # The interesting options are: |
| 563 | # |
| 564 | # name: TEST-NAME |
| 565 | # The name of this test, passed to DejaGNU's `pass' and `fail' |
| 566 | # commands. If omitted, this defaults to FILE, the root of the |
| 567 | # .s and .d files' names. |
| 568 | # |
| 569 | # as: FLAGS |
| 570 | # When assembling, pass FLAGS to the assembler. |
| 571 | # If assembling several files, you can pass different assembler |
| 572 | # options in the "source" directives. See below. |
| 573 | # |
| 574 | # ld: FLAGS |
| 575 | # Link assembled files using FLAGS, in the order of the "source" |
| 576 | # directives, when using multiple files. |
| 577 | # |
| 578 | # objcopy_linked_file: FLAGS |
| 579 | # Run objcopy on the linked file with the specified flags. |
| 580 | # This lets you transform the linked file using objcopy, before the |
| 581 | # result is analyzed by an analyzer program specified below (which |
| 582 | # may in turn *also* be objcopy). |
| 583 | # |
| 584 | # PROG: PROGRAM-NAME |
| 585 | # The name of the program to run to analyze the .o file produced |
| 586 | # by the assembler or the linker output. This can be omitted; |
| 587 | # run_dump_test will guess which program to run by seeing which of |
| 588 | # the flags options below is present. |
| 589 | # |
| 590 | # objdump: FLAGS |
| 591 | # nm: FLAGS |
| 592 | # objcopy: FLAGS |
| 593 | # Use the specified program to analyze the assembler or linker |
| 594 | # output file, and pass it FLAGS, in addition to the output name. |
| 595 | # Note that they are run with LC_ALL=C in the environment to give |
| 596 | # consistent sorting of symbols. |
| 597 | # |
| 598 | # source: SOURCE [FLAGS] |
| 599 | # Assemble the file SOURCE.s using the flags in the "as" directive |
| 600 | # and the (optional) FLAGS. If omitted, the source defaults to |
| 601 | # FILE.s. |
| 602 | # This is useful if several .d files want to share a .s file. |
| 603 | # More than one "source" directive can be given, which is useful |
| 604 | # when testing linking. |
| 605 | # |
| 606 | # xfail: TARGET |
| 607 | # The test is expected to fail on TARGET. This may occur more than |
| 608 | # once. |
| 609 | # |
| 610 | # target: TARGET |
| 611 | # Only run the test for TARGET. This may occur more than once; the |
| 612 | # target being tested must match at least one. |
| 613 | # |
| 614 | # notarget: TARGET |
| 615 | # Do not run the test for TARGET. This may occur more than once; |
| 616 | # the target being tested must not match any of them. |
| 617 | # |
| 618 | # error: REGEX |
| 619 | # An error with message matching REGEX must be emitted for the test |
| 620 | # to pass. The PROG, objdump, nm and objcopy options have no |
| 621 | # meaning and need not supplied if this is present. |
| 622 | # |
| 623 | # warning: REGEX |
| 624 | # Expect a linker warning matching REGEX. It is an error to issue |
| 625 | # both "error" and "warning". |
| 626 | # |
| 627 | # Each option may occur at most once unless otherwise mentioned. |
| 628 | # |
| 629 | # After the option lines come regexp lines. `run_dump_test' calls |
| 630 | # `regexp_diff' to compare the output of the dumping tool against the |
| 631 | # regexps in FILE.d. `regexp_diff' is defined later in this file; see |
