460 # with regexps. The FILE.d file specifies what program to run, and
461 # what to expect in its output.
463 # The FILE.d file begins with zero or more option lines, which specify
464 # flags to pass to the assembler, the program to run to dump the
465 # assembler's output, and the options it wants. The option lines have
470 # OPTION is the name of some option, like "name" or "objdump", and
471 # VALUE is OPTION's value. The valid options are described below.
472 # Whitespace is ignored everywhere, except within VALUE. The option
473 # list ends with the first line that doesn't match the above syntax
474 # (hmm, not great for error detection).
476 # The interesting options are:
479 # The name of this test, passed to DejaGNU's `pass' and `fail'
480 # commands. If omitted, this defaults to FILE, the root of the
481 # .s and .d files' names.
484 # When assembling, pass FLAGS to the assembler.
485 # If assembling several files, you can pass different assembler
486 # options in the "source" directives. See below.
489 # Link assembled files using FLAGS, in the order of the "source"
490 # directives, when using multiple files.
492 # objcopy_linked_file: FLAGS
493 # Run objcopy on the linked file with the specified flags.
494 # This lets you transform the linked file using objcopy, before the
495 # result is analyzed by an analyzer program specified below (which
496 # may in turn *also* be objcopy).
499 # The name of the program to run to analyze the .o file produced
500 # by the assembler or the linker output. This can be omitted;
501 # run_dump_test will guess which program to run by seeing which of
502 # the flags options below is present.
507 # Use the specified program to analyze the assembler or linker
508 # output file, and pass it FLAGS, in addition to the output name.
509 # Note that they are run with LC_ALL=C in the environment to give
510 # consistent sorting of symbols.

513 # Assemble the file SOURCE.s using the flags in the "as" directive
514 # and the (optional) FLAGS. If omitted, the source defaults to
516 # This is useful if several .d files want to share a .s file.
517 # More than one "source" directive can be given, which is useful
518 # when testing linking.
521 # The test is expected to fail on TARGET. This may occur more than
525 # Only run the test for TARGET. This may occur more than once; the
526 # target being tested must match at least one.

534 # to pass. The PROG, objdump, nm and objcopy options have no
535 # meaning and need not supplied if this is present.
537 # Each option may occur at most once unless otherwise mentioned.
539 # After the option lines come regexp lines. `run_dump_test' calls
540 # `regexp_diff' to compare the output of the dumping tool against the
541 # regexps in FILE.d. `regexp_diff' is defined later in this file; see
