525 # what to expect in its output.
527 # The FILE.d file begins with zero or more option lines, which specify

529 # assembler's output, and the options it wants. The option lines have
534 # OPTION is the name of some option, like "name" or "objdump", and

536 # Whitespace is ignored everywhere, except within VALUE. The option
537 # list ends with the first line that doesn't match the above syntax
538 # (hmm, not great for error detection).
540 # The interesting options are:
543 # The name of this test, passed to DejaGNU's `pass' and `fail'
544 # commands. If omitted, this defaults to FILE, the root of the
545 # .s and .d files' names.
548 # When assembling, pass FLAGS to the assembler.
549 # If assembling several files, you can pass different assembler
550 # options in the "source" directives. See below.
553 # Link assembled files using FLAGS, in the order of the "source"
554 # directives, when using multiple files.
556 # objcopy_linked_file: FLAGS
557 # Run objcopy on the linked file with the specified flags.
558 # This lets you transform the linked file using objcopy, before the
559 # result is analyzed by an analyzer program specified below (which
560 # may in turn *also* be objcopy).
563 # The name of the program to run to analyze the .o file produced
564 # by the assembler or the linker output. This can be omitted;
565 # run_dump_test will guess which program to run by seeing which of
566 # the flags options below is present.
571 # Use the specified program to analyze the assembler or linker
572 # output file, and pass it FLAGS, in addition to the output name.

574 # consistent sorting of symbols.

580 # This is useful if several .d files want to share a .s file.

603 # both "error" and "warning".
