| 319 | # |
| 320 | # Assemble a .s file, then run some utility on it and check the output. |
| 321 | # |
| 322 | # There should be an assembly language file named FILE.s in the test |
| 323 | # suite directory, and a pattern file called FILE.d. `run_dump_test' |
| 324 | # will assemble FILE.s, run some tool like `objdump', `objcopy', or |
| 325 | # `nm' on the .o file to produce textual output, and then analyze that |
| 326 | # with regexps. The FILE.d file specifies what program to run, and |
| 327 | # what to expect in its output. |
| 328 | # |
| 329 | # The FILE.d file begins with zero or more option lines, which specify |
| 330 | # flags to pass to the assembler, the program to run to dump the |
| 331 | # assembler's output, and the options it wants. The option lines have |
| 332 | # the syntax: |
| 333 | # |
| 334 | # # OPTION: VALUE |
| 335 | # |
| 336 | # OPTION is the name of some option, like "name" or "objdump", and |
| 337 | # VALUE is OPTION's value. The valid options are described below. |
| 338 | # Whitespace is ignored everywhere, except within VALUE. The option |
| 339 | # list ends with the first line that doesn't match the above syntax. |
| 340 | # However, a line within the options that begins with a #, but doesn't |
| 341 | # have a recognizable option name followed by a colon, is considered a |
| 342 | # comment and entirely ignored. |
| 343 | # |
| 344 | # The optional EXTRA_OPTIONS argument to `run_dump_test' is a list of |
| 345 | # two-element lists. The first element of each is an option name, and |
| 346 | # the second additional arguments to be added on to the end of the |
| 347 | # option list as given in FILE.d. (If omitted, no additional options |
| 348 | # are added.) |
| 349 | # |
| 350 | # The interesting options are: |
| 351 | # |
| 352 | # name: TEST-NAME |
| 353 | # The name of this test, passed to DejaGNU's `pass' and `fail' |
| 354 | # commands. If omitted, this defaults to FILE, the root of the |
| 355 | # .s and .d files' names. |
| 356 | # |
| 357 | # as: FLAGS |
| 358 | # When assembling FILE.s, pass FLAGS to the assembler. |
| 359 | # |
| 360 | # addr2line: FLAGS |
| 361 | # nm: FLAGS |
| 362 | # objcopy: FLAGS |
| 363 | # objdump: FLAGS |
| 364 | # readelf: FLAGS |
| 365 | # Use the specified program to analyze the .o file, and pass it |
| 366 | # FLAGS, in addition to the .o file name. Note that they are run |
| 367 | # with LC_ALL=C in the environment to give consistent sorting |
| 368 | # of symbols. If no FLAGS are needed then use: |
| 369 | # PROG: [nm objcopy objdump readelf addr2line] |
| 370 | # instead. |
| 371 | # Note: for objdump, we automatically replaces the standard section |
| 372 | # names (.text, .data and .bss) by target ones if any (eg. rx-elf |
| 373 | # uses "P" instead of .text). The substition is done for both |
| 374 | # the objdump options (eg: "-j .text" is replaced by "-j P") and the |
| 375 | # reference file. |
| 376 | # |
| 377 | # source: SOURCE |
| 378 | # Assemble the file SOURCE.s. If omitted, this defaults to FILE.s. |
| 379 | # This is useful if several .d files want to share a .s file. |
| 380 | # |
| 381 | # dump: DUMP |
| 382 | # Match against DUMP.d. If omitted, this defaults to FILE.d. This |
| 383 | # is useful if several .d files differ by options only. Options are |
| 384 | # always read from FILE.d. |
| 385 | # |
| 386 | # target: GLOBS... |
| 387 | # Run this test only on a specified list of targets. More precisely, |
| 388 | # each glob in the space-separated list is passed to "istarget"; if |
| 389 | # it evaluates true for any of them, the test will be run, otherwise |
| 390 | # it will be marked unsupported. |
| 391 | # |
| 392 | # not-target: GLOBS... |
| 393 | # Do not run this test on a specified list of targets. Again, |
| 394 | # the each glob in the space-separated list is passed to |
| 395 | # "istarget", and the test is run if it evaluates *false* for |
| 396 | # *all* of them. Otherwise it will be marked unsupported. |
| 397 | # |
| 398 | # skip: GLOBS... |
| 399 | # not-skip: GLOBS... |
| 400 | # These are exactly the same as "not-target" and "target", |
| 401 | # respectively, except that they do nothing at all if the check |
| 402 | # fails. They should only be used in groups, to construct a single |
| 403 | # test which is run on all targets but with variant options or |
| 404 | # expected output on some targets. (For example, see |
| 405 | # gas/arm/inst.d and gas/arm/wince_inst.d.) |
| 406 | # |
| 407 | # error: REGEX |
| 408 | # An error with message matching REGEX must be emitted for the test |
| 409 | # to pass. The PROG, objdump, nm and objcopy options have no |
| 410 | # meaning and need not supplied if this is present. |
| 411 | # |
| 412 | # warning: REGEX |
| 413 | # Expect a gas warning matching REGEX. It is an error to issue |
| 414 | # both "error" and "warning". |
| 415 | # |
| 416 | # stderr: FILE |
| 417 | # FILE contains regexp lines to be matched against the diagnostic |
| 418 | # output of the assembler. This does not preclude the use of |
| 419 | # PROG, nm, objdump, or objcopy. |
| 420 | # |
| 421 | # error-output: FILE |
| 422 | # Means the same as 'stderr', but also indicates that the assembler |
| 423 | # is expected to exit unsuccessfully (therefore PROG, objdump, nm, |
| 424 | # and objcopy have no meaning and should not be supplied). |
| 425 | # |
| 426 | # section-subst: no |
| 427 | # Means that the section substitution for objdump is disabled. |
| 428 | # |
| 429 | # Each option may occur at most once. |
| 430 | # |
| 431 | # After the option lines come regexp lines. `run_dump_test' calls |
| 432 | # `regexp_diff' to compare the output of the dumping tool against the |
| 433 | # regexps in FILE.d. `regexp_diff' is defined in binutils-common.exp; |
