544 # what to expect in its output.
546 # The FILE.d file begins with zero or more option lines, which specify
547 # flags to pass to the assembler, the program to run to dump the
548 # assembler's output, and the options it wants. The option lines have
553 # OPTION is the name of some option, like "name" or "objdump", and
554 # VALUE is OPTION's value. The valid options are described below.
555 # Whitespace is ignored everywhere, except within VALUE. The option
556 # list ends with the first line that doesn't match the above syntax
557 # (hmm, not great for error detection).
559 # The interesting options are:
562 # The name of this test, passed to DejaGNU's `pass' and `fail'
563 # commands. If omitted, this defaults to FILE, the root of the
564 # .s and .d files' names.
567 # When assembling, pass FLAGS to the assembler.
568 # If assembling several files, you can pass different assembler
569 # options in the "source" directives. See below.
572 # Link assembled files using FLAGS, in the order of the "source"
573 # directives, when using multiple files.
575 # objcopy_linked_file: FLAGS
576 # Run objcopy on the linked file with the specified flags.
577 # This lets you transform the linked file using objcopy, before the
578 # result is analyzed by an analyzer program specified below (which
579 # may in turn *also* be objcopy).
582 # The name of the program to run to analyze the .o file produced
583 # by the assembler or the linker output. This can be omitted;
584 # run_dump_test will guess which program to run by seeing which of
585 # the flags options below is present.
590 # Use the specified program to analyze the assembler or linker
591 # output file, and pass it FLAGS, in addition to the output name.
592 # Note that they are run with LC_ALL=C in the environment to give
593 # consistent sorting of symbols.

597 # and the (optional) FLAGS. If omitted, the source defaults to
599 # This is useful if several .d files want to share a .s file.
600 # More than one "source" directive can be given, which is useful
601 # when testing linking.
604 # The test is expected to fail on TARGET. This may occur more than
608 # Only run the test for TARGET. This may occur more than once; the
609 # target being tested must match at least one.
612 # Do not run the test for TARGET. This may occur more than once;

616 # An error with message matching REGEX must be emitted for the test
617 # to pass. The PROG, objdump, nm and objcopy options have no
618 # meaning and need not supplied if this is present.
621 # Expect a linker warning matching REGEX. It is an error to issue
622 # both "error" and "warning".
624 # Each option may occur at most once unless otherwise mentioned.
626 # After the option lines come regexp lines. `run_dump_test' calls
627 # `regexp_diff' to compare the output of the dumping tool against the
628 # regexps in FILE.d. `regexp_diff' is defined later in this file; see
