346 # Assemble a .s file, then run some utility on it and check the output.
347 #
348 # There should be an assembly language file named FILE.s in the test
349 # suite directory, and a pattern file called FILE.d. `run_dump_test'
350 # will assemble FILE.s, run some tool like `objdump', `objcopy', or
351 # `nm' on the .o file to produce textual output, and then analyze that
352 # with regexps. The FILE.d file specifies what program to run, and
353 # what to expect in its output.
354 #
355 # The FILE.d file begins with zero or more option lines, which specify
356 # flags to pass to the assembler, the program to run to dump the
357 # assembler's output, and the options it wants. The option lines have
358 # the syntax:
359 #
360 # # OPTION: VALUE
361 #
362 # OPTION is the name of some option, like "name" or "objdump", and
363 # VALUE is OPTION's value. The valid options are described below.
364 # Whitespace is ignored everywhere, except within VALUE. The option
365 # list ends with the first line that doesn't match the above syntax.
366 # However, a line within the options that begins with a #, but doesn't
367 # have a recognizable option name followed by a colon, is considered a
368 # comment and entirely ignored.
369 #
370 # The optional EXTRA_OPTIONS argument to `run_dump_test' is a list of
371 # two-element lists. The first element of each is an option name, and
372 # the second additional arguments to be added on to the end of the
373 # option list as given in FILE.d. (If omitted, no additional options
374 # are added.)
375 #
376 # The interesting options are:
377 #
378 # name: TEST-NAME
379 # The name of this test, passed to DejaGNU's `pass' and `fail'
380 # commands. If omitted, this defaults to FILE, the root of the
381 # .s and .d files' names.
382 #
383 # as: FLAGS
384 # When assembling FILE.s, pass FLAGS to the assembler.
385 #
386 # nm: FLAGS
387 # objcopy: FLAGS
388 # objdump: FLAGS
389 # readelf: FLAGS
390 # Use the specified program to analyze the .o file, and pass it
391 # FLAGS, in addition to the .o file name. Note that they are run
392 # with LC_ALL=C in the environment to give consistent sorting
393 # of symbols. If no FLAGS are needed then use:
394 # PROG: [nm objcopy objdump readelf]
395 # instead.
396 #
397 # source: SOURCE
398 # Assemble the file SOURCE.s. If omitted, this defaults to FILE.s.
399 # This is useful if several .d files want to share a .s file.
400 #
401 # target: GLOBS...
402 # Run this test only on a specified list of targets. More precisely,
403 # each glob in the space-separated list is passed to "istarget"; if
404 # it evaluates true for any of them, the test will be run, otherwise
405 # it will be marked unsupported.
406 #
407 # not-target: GLOBS...
408 # Do not run this test on a specified list of targets. Again,
409 # the each glob in the space-separated list is passed to
410 # "istarget", and the test is run if it evaluates *false* for
411 # *all* of them. Otherwise it will be marked unsupported.
412 #
413 # skip: GLOBS...
414 # not-skip: GLOBS...
415 # These are exactly the same as "not-target" and "target",
416 # respectively, except that they do nothing at all if the check
417 # fails. They should only be used in groups, to construct a single
418 # test which is run on all targets but with variant options or
419 # expected output on some targets. (For example, see
420 # gas/arm/inst.d and gas/arm/wince_inst.d.)
421 #
422 # error: REGEX
423 # An error with message matching REGEX must be emitted for the test
424 # to pass. The PROG, objdump, nm and objcopy options have no
425 # meaning and need not supplied if this is present.
426 #
427 # warning: REGEX
428 # Expect a gas warning matching REGEX. It is an error to issue
429 # both "error" and "warning".
430 #
431 # stderr: FILE
432 # FILE contains regexp lines to be matched against the diagnostic
433 # output of the assembler. This does not preclude the use of
434 # PROG, nm, objdump, or objcopy.
435 #
436 # error-output: FILE
437 # Means the same as 'stderr', but also indicates that the assembler
438 # is expected to exit unsuccessfully (therefore PROG, objdump, nm,
439 # and objcopy have no meaning and should not be supplied).
440 #
441 # Each option may occur at most once.
442 #
443 # After the option lines come regexp lines. `run_dump_test' calls
444 # `regexp_diff' to compare the output of the dumping tool against the
445 # regexps in FILE.d. `regexp_diff' is defined later in this file; see
446 # further comments there.
