| 224 | # |
| 225 | # Assemble a .s file, then run some utility on it and check the output. |
| 226 | # |
| 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: |
| 238 | # |
| 239 | # # OPTION: VALUE |
| 240 | # |
| 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 | # |
| 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 | # |
| 253 | # The interesting options are: |
| 254 | # |
| 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. |
| 259 | # |
| 260 | # as: FLAGS |
| 261 | # When assembling FILE.s, pass FLAGS to the assembler. |
| 262 | # |
| 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. |
| 268 | # |
| 269 | # objdump: FLAGS |
| 270 | # nm: FLAGS |
| 271 | # objcopy: FLAGS |
| 272 | # Use the specified program to analyze the .o file, and pass it |
| 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. |
| 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 | # |
| 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 | # |
| 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. |
