192 | # run_dump_test FILE (optional:) EXTRA_OPTIONS | |
193 | # | |
194 | # Assemble a .s file, then run some utility on it and check the output. | |
195 | # | |
196 | # There should be an assembly language file named FILE.s in the test | |
197 | # suite directory, and a pattern file called FILE.d. `run_dump_test' | |
198 | # will assemble FILE.s, run some tool like `objdump', `objcopy', or | |
199 | # `nm' on the .o file to produce textual output, and then analyze that | |
200 | # with regexps. The FILE.d file specifies what program to run, and | |
201 | # what to expect in its output. | |
202 | # | |
203 | # The FILE.d file begins with zero or more option lines, which specify | |
204 | # flags to pass to the assembler, the program to run to dump the | |
205 | # assembler's output, and the options it wants. The option lines have | |
206 | # the syntax: | |
207 | # | |
208 | # # OPTION: VALUE | |
209 | # | |
210 | # OPTION is the name of some option, like "name" or "objdump", and | |
211 | # VALUE is OPTION's value. The valid options are described below. | |
212 | # Whitespace is ignored everywhere, except within VALUE. The option | |
213 | # list ends with the first line that doesn't match the above syntax. | |
214 | # However, a line within the options that begins with a #, but doesn't | |
215 | # have a recognizable option name followed by a colon, is considered a | |
216 | # comment and entirely ignored. | |
217 | # | |
218 | # The optional EXTRA_OPTIONS argument to `run_dump_test' is a list of | |
219 | # two-element lists. The first element of each is an option name, and | |
220 | # the second additional arguments to be added on to the end of the | |
221 | # option list as given in FILE.d. (If omitted, no additional options | |
222 | # are added.) | |
223 | # | |
224 | # The interesting options are: | |
225 | # | |
226 | # name: TEST-NAME | |
227 | # The name of this test, passed to DejaGNU's `pass' and `fail' | |
228 | # commands. If omitted, this defaults to FILE, the root of the | |
229 | # .s and .d files' names. | |
230 | # | |
231 | # as: FLAGS | |
232 | # When assembling FILE.s, pass FLAGS to the assembler. | |
233 | # | |
234 | # PROG: PROGRAM-NAME | |
235 | # The name of the program to run to analyze the .o file produced | |
236 | # by the assembler. This can be omitted; run_dump_test will guess | |
237 | # which program to run by seeing which of the flags options below | |
238 | # is present. | |
239 | # | |
240 | # objdump: FLAGS | |
241 | # nm: FLAGS | |
242 | # objcopy: FLAGS | |
243 | # Use the specified program to analyze the .o file, and pass it | |
244 | # FLAGS, in addition to the .o file name. Note that they are run | |
245 | # with LC_ALL=C in the environment to give consistent sorting | |
246 | # of symbols. | |
247 | # | |
248 | # source: SOURCE | |
249 | # Assemble the file SOURCE.s. If omitted, this defaults to FILE.s. | |
250 | # This is useful if several .d files want to share a .s file. | |
251 | # | |
252 | # target: GLOBS... | |
253 | # Run this test only on a specified list of targets. More precisely, | |
254 | # each glob in the space-separated list is passed to "istarget"; if | |
255 | # it evaluates true for any of them, the test will be run, otherwise | |
256 | # it will be marked unsupported. | |
257 | # | |
258 | # not-target: GLOBS... | |
259 | # Do not run this test on a specified list of targets. Again, | |
260 | # the each glob in the space-separated list is passed to | |
261 | # "istarget", and the test is run if it evaluates *false* for | |
262 | # *all* of them. Otherwise it will be marked unsupported. | |
263 | # | |
264 | # skip: GLOBS... | |
265 | # not-skip: GLOBS... | |
266 | # These are exactly the same as "not-target" and "target", | |
267 | # respectively, except that they do nothing at all if the check | |
268 | # fails. They should only be used in groups, to construct a single | |
269 | # test which is run on all targets but with variant options or | |
270 | # expected output on some targets. (For example, see | |
271 | # gas/arm/inst.d and gas/arm/wince_inst.d.) | |
272 | # | |
273 | # error: REGEX | |
274 | # An error with message matching REGEX must be emitted for the test | |
275 | # to pass. The PROG, objdump, nm and objcopy options have no | |
276 | # meaning and need not supplied if this is present. | |
277 | # | |
278 | # warning: REGEX | |
279 | # Expect a gas warning matching REGEX. It is an error to issue | |
280 | # both "error" and "warning". | |
281 | # | |
282 | # stderr: FILE | |
283 | # FILE contains regexp lines to be matched against the diagnostic | |
284 | # output of the assembler. This does not preclude the use of | |
285 | # PROG, nm, objdump, or objcopy. | |
286 | # | |
287 | # error-output: FILE | |
288 | # Means the same as 'stderr', but also indicates that the assembler | |
289 | # is expected to exit unsuccessfully (therefore PROG, objdump, nm, | |
290 | # and objcopy have no meaning and should not be supplied). | |
291 | # | |
292 | # Each option may occur at most once. | |
293 | # | |
294 | # After the option lines come regexp lines. `run_dump_test' calls | |
295 | # `regexp_diff' to compare the output of the dumping tool against the | |
296 | # regexps in FILE.d. `regexp_diff' is defined later in this file; see | |
297 | # further comments there. | |
