255 # run_dump_test FILE (optional:) EXTRA_OPTIONS
256 #
257 # Assemble a .s file, then run some utility on it and check the output.
258 #
259 # There should be an assembly language file named FILE.s in the test
260 # suite directory, and a pattern file called FILE.d. `run_dump_test'
261 # will assemble FILE.s, run some tool like `objdump', `objcopy', or
262 # `nm' on the .o file to produce textual output, and then analyze that
263 # with regexps. The FILE.d file specifies what program to run, and
264 # what to expect in its output.
265 #
266 # The FILE.d file begins with zero or more option lines, which specify
267 # flags to pass to the assembler, the program to run to dump the
268 # assembler's output, and the options it wants. The option lines have
269 # the syntax:
270 #
271 # # OPTION: VALUE
272 #
273 # OPTION is the name of some option, like "name" or "objdump", and
274 # VALUE is OPTION's value. The valid options are described below.
275 # Whitespace is ignored everywhere, except within VALUE. The option
276 # list ends with the first line that doesn't match the above syntax.
277 # However, a line within the options that begins with a #, but doesn't
278 # have a recognizable option name followed by a colon, is considered a
279 # comment and entirely ignored.
280 #
281 # The optional EXTRA_OPTIONS argument to `run_dump_test' is a list of
282 # two-element lists. The first element of each is an option name, and
283 # the second additional arguments to be added on to the end of the
284 # option list as given in FILE.d. (If omitted, no additional options
285 # are added.)
286 #
287 # The interesting options are:
288 #
289 # name: TEST-NAME
290 # The name of this test, passed to DejaGNU's `pass' and `fail'
291 # commands. If omitted, this defaults to FILE, the root of the
292 # .s and .d files' names.
293 #
294 # as: FLAGS
295 # When assembling FILE.s, pass FLAGS to the assembler.
296 #
297 # PROG: PROGRAM-NAME
298 # The name of the program to run to analyze the .o file produced
299 # by the assembler. This can be omitted; run_dump_test will guess
300 # which program to run by seeing which of the flags options below
301 # is present.
302 #
303 # objdump: FLAGS
304 # nm: FLAGS
305 # objcopy: FLAGS
306 # Use the specified program to analyze the .o file, and pass it
307 # FLAGS, in addition to the .o file name. Note that they are run
308 # with LC_ALL=C in the environment to give consistent sorting
309 # of symbols.
310 #
311 # source: SOURCE
312 # Assemble the file SOURCE.s. If omitted, this defaults to FILE.s.
313 # This is useful if several .d files want to share a .s file.
314 #
315 # target: GLOBS...
316 # Run this test only on a specified list of targets. More precisely,
317 # each glob in the space-separated list is passed to "istarget"; if
318 # it evaluates true for any of them, the test will be run, otherwise
319 # it will be marked unsupported.
320 #
321 # not-target: GLOBS...
322 # Do not run this test on a specified list of targets. Again,
323 # the each glob in the space-separated list is passed to
324 # "istarget", and the test is run if it evaluates *false* for
325 # *all* of them. Otherwise it will be marked unsupported.
326 #
327 # skip: GLOBS...
328 # not-skip: GLOBS...
329 # These are exactly the same as "not-target" and "target",
330 # respectively, except that they do nothing at all if the check
331 # fails. They should only be used in groups, to construct a single
332 # test which is run on all targets but with variant options or
333 # expected output on some targets. (For example, see
334 # gas/arm/inst.d and gas/arm/wince_inst.d.)
335 #
336 # error: REGEX
337 # An error with message matching REGEX must be emitted for the test
338 # to pass. The PROG, objdump, nm and objcopy options have no
339 # meaning and need not supplied if this is present.
340 #
341 # warning: REGEX
342 # Expect a gas warning matching REGEX. It is an error to issue
343 # both "error" and "warning".
344 #
345 # stderr: FILE
346 # FILE contains regexp lines to be matched against the diagnostic
347 # output of the assembler. This does not preclude the use of
348 # PROG, nm, objdump, or objcopy.
349 #
350 # error-output: FILE
351 # Means the same as 'stderr', but also indicates that the assembler
352 # is expected to exit unsuccessfully (therefore PROG, objdump, nm,
353 # and objcopy have no meaning and should not be supplied).
354 #
355 # Each option may occur at most once.
356 #
357 # After the option lines come regexp lines. `run_dump_test' calls
358 # `regexp_diff' to compare the output of the dumping tool against the
359 # regexps in FILE.d. `regexp_diff' is defined later in this file; see
360 # further comments there.
