432 # Assemble a .s file, then run some utility on it and check the output.
433 #
434 # There should be an assembly language file named FILE.s in the test
435 # suite directory, and a pattern file called FILE.d. `run_dump_test'
436 # will assemble FILE.s, run some tool like `objdump', `objcopy', or
437 # `nm' on the .o file to produce textual output, and then analyze that
438 # with regexps. The FILE.d file specifies what program to run, and
439 # what to expect in its output.
440 #
441 # The FILE.d file begins with zero or more option lines, which specify
442 # flags to pass to the assembler, the program to run to dump the
443 # assembler's output, and the options it wants. The option lines have
444 # the syntax:
445 #
446 # # OPTION: VALUE
447 #
448 # OPTION is the name of some option, like "name" or "objdump", and
449 # VALUE is OPTION's value. The valid options are described below.
450 # Whitespace is ignored everywhere, except within VALUE. The option
451 # list ends with the first line that doesn't match the above syntax
452 # (hmm, not great for error detection).
453 #
454 # The interesting options are:
455 #
456 # name: TEST-NAME
457 # The name of this test, passed to DejaGNU's `pass' and `fail'
458 # commands. If omitted, this defaults to FILE, the root of the
459 # .s and .d files' names.
460 #
461 # as: FLAGS
462 # When assembling, pass FLAGS to the assembler.
463 # If assembling several files, you can pass different assembler
464 # options in the "source" directives. See below.
465 #
466 # ld: FLAGS
467 # Link assembled files using FLAGS, in the order of the "source"
468 # directives, when using multiple files.
469 #
470 # objcopy_linked_file: FLAGS
471 # Run objcopy on the linked file with the specified flags.
472 # This lets you transform the linked file using objcopy, before the
473 # result is analyzed by an analyzer program specified below (which
474 # may in turn *also* be objcopy).
475 #
476 # PROG: PROGRAM-NAME
477 # The name of the program to run to analyze the .o file produced
478 # by the assembler or the linker output. This can be omitted;
479 # run_dump_test will guess which program to run by seeing which of
480 # the flags options below is present.
481 #
482 # objdump: FLAGS
483 # nm: FLAGS
484 # objcopy: FLAGS
485 # Use the specified program to analyze the assembler or linker
486 # output file, and pass it FLAGS, in addition to the output name.
487 # Note that they are run with LC_ALL=C in the environment to give
488 # consistent sorting of symbols.
489 #
490 # source: SOURCE [FLAGS]
491 # Assemble the file SOURCE.s using the flags in the "as" directive
492 # and the (optional) FLAGS. If omitted, the source defaults to
493 # FILE.s.
494 # This is useful if several .d files want to share a .s file.
495 # More than one "source" directive can be given, which is useful
496 # when testing linking.
497 #
498 # xfail: TARGET
499 # The test is expected to fail on TARGET. This may occur more than
500 # once.
501 #
502 # target: TARGET
503 # Only run the test for TARGET. This may occur more than once; the
504 # target being tested must match at least one.
505 #
506 # notarget: TARGET
507 # Do not run the test for TARGET. This may occur more than once;
508 # the target being tested must not match any of them.
509 #
510 # error: REGEX
511 # An error with message matching REGEX must be emitted for the test
512 # to pass. The PROG, objdump, nm and objcopy options have no
513 # meaning and need not supplied if this is present.
514 #
515 # Each option may occur at most once unless otherwise mentioned.
516 #
517 # After the option lines come regexp lines. `run_dump_test' calls
518 # `regexp_diff' to compare the output of the dumping tool against the
519 # regexps in FILE.d. `regexp_diff' is defined later in this file; see
