419 # There should be an assembly language file named FILE.s in the test
420 # suite directory, and a pattern file called FILE.d. `run_dump_test'
421 # will assemble FILE.s, run some tool like `objdump', `objcopy', or
422 # `nm' on the .o file to produce textual output, and then analyze that
423 # with regexps. The FILE.d file specifies what program to run, and
424 # what to expect in its output.
426 # The FILE.d file begins with zero or more option lines, which specify
427 # flags to pass to the assembler, the program to run to dump the
428 # assembler's output, and the options it wants. The option lines have
433 # OPTION is the name of some option, like "name" or "objdump", and
434 # VALUE is OPTION's value. The valid options are described below.
435 # Whitespace is ignored everywhere, except within VALUE. The option
436 # list ends with the first line that doesn't match the above syntax.
437 # However, a line within the options that begins with a #, but doesn't
438 # have a recognizable option name followed by a colon, is considered a
439 # comment and entirely ignored.
441 # The optional EXTRA_OPTIONS argument to `run_dump_test' is a list of
442 # two-element lists. The first element of each is an option name, and
443 # the second additional arguments to be added on to the end of the
444 # option list as given in FILE.d. (If omitted, no additional options
447 # The interesting options are:
450 # The name of this test, passed to DejaGNU's `pass' and `fail'
451 # commands. If omitted, this defaults to FILE, the root of the
452 # .s and .d files' names.
455 # When assembling FILE.s, pass FLAGS to the assembler.
462 # Use the specified program to analyze the .o file, and pass it
463 # FLAGS, in addition to the .o file name. Note that they are run
464 # with LC_ALL=C in the environment to give consistent sorting
465 # of symbols. If no FLAGS are needed then use:
466 # PROG: [nm objcopy objdump readelf addr2line]
468 # Note: for objdump, we automatically replaces the standard section
469 # names (.text, .data and .bss) by target ones if any (eg. rx-elf
470 # uses "P" instead of .text). The substition is done for both
471 # the objdump options (eg: "-j .text" is replaced by "-j P") and the
475 # Assemble the file SOURCE.s. If omitted, this defaults to FILE.s.
476 # This is useful if several .d files want to share a .s file.
479 # Match against DUMP.d. If omitted, this defaults to FILE.d. This
480 # is useful if several .d files differ by options only. Options are
481 # always read from FILE.d.
484 # Run this test only on a specified list of targets. More precisely,
485 # each glob in the space-separated list is passed to "istarget"; if
486 # it evaluates true for any of them, the test will be run, otherwise
487 # it will be marked unsupported.
489 # not-target: GLOBS...
490 # Do not run this test on a specified list of targets. Again,
491 # the each glob in the space-separated list is passed to
492 # "istarget", and the test is run if it evaluates *false* for
493 # *all* of them. Otherwise it will be marked unsupported.
497 # These are exactly the same as "not-target" and "target",
498 # respectively, except that they do nothing at all if the check
499 # fails. They should only be used in groups, to construct a single
500 # test which is run on all targets but with variant options or
501 # expected output on some targets. (For example, see
502 # gas/arm/inst.d and gas/arm/wince_inst.d.)
505 # An error with message matching REGEX must be emitted for the test
506 # to pass. The PROG, objdump, nm and objcopy options have no
507 # meaning and need not supplied if this is present.
510 # Expect a gas warning matching REGEX. It is an error to issue
511 # both "error" and "warning".
514 # FILE contains regexp lines to be matched against the diagnostic
515 # output of the assembler. This does not preclude the use of
516 # PROG, nm, objdump, or objcopy.
519 # Means the same as 'stderr', but also indicates that the assembler
520 # is expected to exit unsuccessfully (therefore PROG, objdump, nm,
521 # and objcopy have no meaning and should not be supplied).
524 # Means that the section substitution for objdump is disabled.
526 # Each option may occur at most once.
528 # After the option lines come regexp lines. `run_dump_test' calls
529 # `regexp_diff' to compare the output of the dumping tool against the
530 # regexps in FILE.d. `regexp_diff' is defined later in this file; see
