224 | # |
225 | # Assemble a .s file, then run some utility on it and check the output. | |
139e4a70 | 226 | # |
252b5132 RH |
227 | # There should be an assembly language file named FILE.s in the test |
228 | # suite directory, and a pattern file called FILE.d. `run_dump_test' | |
229 | # will assemble FILE.s, run some tool like `objdump', `objcopy', or | |
230 | # `nm' on the .o file to produce textual output, and then analyze that | |
231 | # with regexps. The FILE.d file specifies what program to run, and | |
232 | # what to expect in its output. | |
233 | # | |
234 | # The FILE.d file begins with zero or more option lines, which specify | |
235 | # flags to pass to the assembler, the program to run to dump the | |
236 | # assembler's output, and the options it wants. The option lines have | |
237 | # the syntax: | |
139e4a70 | 238 | # |
252b5132 | 239 | # # OPTION: VALUE |
139e4a70 | 240 | # |
252b5132 RH |
241 | # OPTION is the name of some option, like "name" or "objdump", and |
242 | # VALUE is OPTION's value. The valid options are described below. | |
243 | # Whitespace is ignored everywhere, except within VALUE. The option | |
244 | # list ends with the first line that doesn't match the above syntax | |
245 | # (hmm, not great for error detection). | |
246 | # | |
e8119602 CD |
247 | # The optional EXTRA_OPTIONS argument to `run_dump_test' is a list of |
248 | # two-element lists. The first element of each is an option name, and | |
249 | # the second additional arguments to be added on to the end of the | |
250 | # option list as given in FILE.d. (If omitted, no additional options | |
251 | # are added.) | |
252 | # | |
252b5132 | 253 | # The interesting options are: |
139e4a70 | 254 | # |
252b5132 RH |
255 | # name: TEST-NAME |
256 | # The name of this test, passed to DejaGNU's `pass' and `fail' | |
257 | # commands. If omitted, this defaults to FILE, the root of the | |
258 | # .s and .d files' names. | |
139e4a70 | 259 | # |
252b5132 RH |
260 | # as: FLAGS |
261 | # When assembling FILE.s, pass FLAGS to the assembler. | |
139e4a70 | 262 | # |
252b5132 RH |
263 | # PROG: PROGRAM-NAME |
264 | # The name of the program to run to analyze the .o file produced | |
265 | # by the assembler. This can be omitted; run_dump_test will guess | |
266 | # which program to run by seeing which of the flags options below | |
267 | # is present. | |
139e4a70 | 268 | # |
252b5132 RH |
269 | # objdump: FLAGS |
270 | # nm: FLAGS | |
271 | # objcopy: FLAGS | |
272 | # Use the specified program to analyze the .o file, and pass it | |
139e4a70 AM |
273 | # FLAGS, in addition to the .o file name. Note that they are run |
274 | # with LC_ALL=C in the environment to give consistent sorting | |
275 | # of symbols. | |
252b5132 RH |
276 | # |
277 | # source: SOURCE | |
278 | # Assemble the file SOURCE.s. If omitted, this defaults to FILE.s. | |
279 | # This is useful if several .d files want to share a .s file. | |
280 | # | |
8c2784a5 TR |
281 | # error: REGEX |
282 | # An error with message matching REGEX must be emitted for the test | |
283 | # to pass. The PROG, objdump, nm and objcopy options have no | |
284 | # meaning and need not supplied if this is present. | |
285 | # | |
252b5132 RH |
286 | # Each option may occur at most once. |
287 | # | |
288 | # After the option lines come regexp lines. `run_dump_test' calls | |
289 | # `regexp_diff' to compare the output of the dumping tool against the | |
290 | # regexps in FILE.d. `regexp_diff' is defined later in this file; see | |
291 | # further comments there. | |
