364 # Assemble a .s file, then run some utility on it and check the output.
365 #
366 # There should be an assembly language file named FILE.s in the test
367 # suite directory, and a pattern file called FILE.d. `run_dump_test'
368 # will assemble FILE.s, run some tool like `objdump', `objcopy', or
369 # `nm' on the .o file to produce textual output, and then analyze that
370 # with regexps. The FILE.d file specifies what program to run, and
371 # what to expect in its output.
372 #
373 # The FILE.d file begins with zero or more option lines, which specify
374 # flags to pass to the assembler, the program to run to dump the
375 # assembler's output, and the options it wants. The option lines have
376 # the syntax:
377 #
378 # # OPTION: VALUE
379 #
380 # OPTION is the name of some option, like "name" or "objdump", and
381 # VALUE is OPTION's value. The valid options are described below.
382 # Whitespace is ignored everywhere, except within VALUE. The option
383 # list ends with the first line that doesn't match the above syntax.
384 # However, a line within the options that begins with a #, but doesn't
385 # have a recognizable option name followed by a colon, is considered a
386 # comment and entirely ignored.
387 #
388 # The optional EXTRA_OPTIONS argument to `run_dump_test' is a list of
389 # two-element lists. The first element of each is an option name, and
390 # the second additional arguments to be added on to the end of the
391 # option list as given in FILE.d. (If omitted, no additional options
392 # are added.)
393 #
394 # The interesting options are:
395 #
396 # name: TEST-NAME
397 # The name of this test, passed to DejaGNU's `pass' and `fail'
398 # commands. If omitted, this defaults to FILE, the root of the
399 # .s and .d files' names.
400 #
401 # as: FLAGS
402 # When assembling FILE.s, pass FLAGS to the assembler.
403 #
404 # nm: FLAGS
405 # objcopy: FLAGS
406 # objdump: FLAGS
407 # readelf: FLAGS
408 # Use the specified program to analyze the .o file, and pass it
409 # FLAGS, in addition to the .o file name. Note that they are run
410 # with LC_ALL=C in the environment to give consistent sorting
411 # of symbols. If no FLAGS are needed then use:
412 # PROG: [nm objcopy objdump readelf]
413 # instead.
414 #
415 # source: SOURCE
416 # Assemble the file SOURCE.s. If omitted, this defaults to FILE.s.
417 # This is useful if several .d files want to share a .s file.
418 #
419 # target: GLOBS...
420 # Run this test only on a specified list of targets. More precisely,
421 # each glob in the space-separated list is passed to "istarget"; if
422 # it evaluates true for any of them, the test will be run, otherwise
423 # it will be marked unsupported.
424 #
425 # not-target: GLOBS...
426 # Do not run this test on a specified list of targets. Again,
427 # the each glob in the space-separated list is passed to
428 # "istarget", and the test is run if it evaluates *false* for
429 # *all* of them. Otherwise it will be marked unsupported.
430 #
431 # skip: GLOBS...
432 # not-skip: GLOBS...
433 # These are exactly the same as "not-target" and "target",
434 # respectively, except that they do nothing at all if the check
435 # fails. They should only be used in groups, to construct a single
436 # test which is run on all targets but with variant options or
437 # expected output on some targets. (For example, see
438 # gas/arm/inst.d and gas/arm/wince_inst.d.)
439 #
440 # error: REGEX
441 # An error with message matching REGEX must be emitted for the test
442 # to pass. The PROG, objdump, nm and objcopy options have no
443 # meaning and need not supplied if this is present.
444 #
445 # warning: REGEX
446 # Expect a gas warning matching REGEX. It is an error to issue
447 # both "error" and "warning".
448 #
449 # stderr: FILE
450 # FILE contains regexp lines to be matched against the diagnostic
451 # output of the assembler. This does not preclude the use of
452 # PROG, nm, objdump, or objcopy.
453 #
454 # error-output: FILE
455 # Means the same as 'stderr', but also indicates that the assembler
456 # is expected to exit unsuccessfully (therefore PROG, objdump, nm,
457 # and objcopy have no meaning and should not be supplied).
458 #
459 # Each option may occur at most once.
460 #
461 # After the option lines come regexp lines. `run_dump_test' calls
462 # `regexp_diff' to compare the output of the dumping tool against the
463 # regexps in FILE.d. `regexp_diff' is defined later in this file; see
464 # further comments there.
