535 # `nm' on the .o file to produce textual output, and then analyze that
536 # with regexps. The FILE.d file specifies what program to run, and
537 # what to expect in its output.
539 # The FILE.d file begins with zero or more option lines, which specify
540 # flags to pass to the assembler, the program to run to dump the
541 # assembler's output, and the options it wants. The option lines have
546 # OPTION is the name of some option, like "name" or "objdump", and
547 # VALUE is OPTION's value. The valid options are described below.
548 # Whitespace is ignored everywhere, except within VALUE. The option
549 # list ends with the first line that doesn't match the above syntax
550 # (hmm, not great for error detection).
552 # The interesting options are:
555 # The name of this test, passed to DejaGNU's `pass' and `fail'
556 # commands. If omitted, this defaults to FILE, the root of the
557 # .s and .d files' names.
560 # When assembling, pass FLAGS to the assembler.
561 # If assembling several files, you can pass different assembler
562 # options in the "source" directives. See below.
565 # Link assembled files using FLAGS, in the order of the "source"
566 # directives, when using multiple files.
568 # ld_after_inputfiles: FLAGS
569 # Similar to "ld", but put after all input files.
571 # objcopy_linked_file: FLAGS
572 # Run objcopy on the linked file with the specified flags.
573 # This lets you transform the linked file using objcopy, before the
574 # result is analyzed by an analyzer program specified below (which
575 # may in turn *also* be objcopy).
578 # The name of the program to run to analyze the .o file produced
579 # by the assembler or the linker output. This can be omitted;
580 # run_dump_test will guess which program to run by seeing which of
581 # the flags options below is present.
586 # Use the specified program to analyze the assembler or linker
587 # output file, and pass it FLAGS, in addition to the output name.
588 # Note that they are run with LC_ALL=C in the environment to give
589 # consistent sorting of symbols.

592 # Assemble the file SOURCE.s using the flags in the "as" directive
593 # and the (optional) FLAGS. If omitted, the source defaults to
595 # This is useful if several .d files want to share a .s file.
596 # More than one "source" directive can be given, which is useful
597 # when testing linking.
600 # The test is expected to fail on TARGET. This may occur more than
604 # Only run the test for TARGET. This may occur more than once; the
605 # target being tested must match at least one. You may provide target
606 # name "cfi" for any target supporting the CFI statements.
609 # Do not run the test for TARGET. This may occur more than once;
610 # the target being tested must not match any of them.
613 # An error with message matching REGEX must be emitted for the test
614 # to pass. The PROG, objdump, nm and objcopy options have no
615 # meaning and need not supplied if this is present.
618 # Expect a linker warning matching REGEX. It is an error to issue
619 # both "error" and "warning".
