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

505 # and the (optional) FLAGS. If omitted, the source defaults to
507 # This is useful if several .d files want to share a .s file.
508 # More than one "source" directive can be given, which is useful
509 # when testing linking.
512 # The test is expected to fail on TARGET. This may occur more than
516 # Only run the test for TARGET. This may occur more than once; the

526 # meaning and need not supplied if this is present.
