502 # The FILE.d file begins with zero or more option lines

program to run to dump the
504 # assembler
's output, and the options it wants. The option lines have
509 # OPTION is the name of some option, like "name" or "objdump", and
510 # VALUE is OPTION's value. The valid options are described below.
511 # Whitespace is ignored everywhere
, except within VALUE. The option
512 # list ends with the first line that doesn
't match the above syntax
513 # (hmm, not great for error detection).
515 # The interesting options are:
518 # The name of this test, passed to DejaGNU's `pass
' and `fail'
519 # commands.
If omitted
, this defaults to FILE

524 # If assembling several files, you can pass different assembler
525 # options in the "source" directives. See below.

529 # directives, when using multiple files.
531 # objcopy_linked_file: FLAGS
532 # Run objcopy on the linked file with the specified flags.
533 # This lets you transform the linked file using objcopy, before the
534 # result is analyzed by an analyzer program specified below (which
535 # may in turn *also* be objcopy).
538 # The name of the program to run to analyze the .o file produced
539 # by the assembler or the linker output. This can be omitted;
540 # run_dump_test will guess which program to run by seeing which of
541 # the flags options below is present.
546 # Use the specified program to analyze the assembler or linker
547 # output file, and pass it FLAGS, in addition to the output name.
548 # Note that they are run with LC_ALL=C in the environment to give
549 # consistent sorting of symbols.

552 # Assemble the file SOURCE.s using the flags in the "as" directive
553 # and the (optional) FLAGS. If omitted, the source defaults to
555 # This is useful if several .d files want to share a .s file.
556 # More than one "source" directive can be given, which is useful
557 # when testing linking.
560 # The test is expected to fail on TARGET. This may occur more than
564 # Only run the test for TARGET. This may occur more than once; the
