186 | # | |
187 | # Assemble a .s file, then run some utility on it and check the output. | |
188 | # | |
189 | # There should be an assembly language file named FILE.s in the test | |
190 | # suite directory, and a pattern file called FILE.d. `run_dump_test' | |
191 | # will assemble FILE.s, run some tool like `objdump', `objcopy', or | |
192 | # `nm' on the .o file to produce textual output, and then analyze that | |
193 | # with regexps. The FILE.d file specifies what program to run, and | |
194 | # what to expect in its output. | |
195 | # | |
196 | # The FILE.d file begins with zero or more option lines, which specify | |
197 | # flags to pass to the assembler, the program to run to dump the | |
198 | # assembler's output, and the options it wants. The option lines have | |
199 | # the syntax: | |
200 | # | |
201 | # # OPTION: VALUE | |
202 | # | |
203 | # OPTION is the name of some option, like "name" or "objdump", and | |
204 | # VALUE is OPTION's value. The valid options are described below. | |
205 | # Whitespace is ignored everywhere, except within VALUE. The option | |
206 | # list ends with the first line that doesn't match the above syntax | |
207 | # (hmm, not great for error detection). | |
208 | # | |
209 | # The interesting options are: | |
210 | # | |
211 | # name: TEST-NAME | |
212 | # The name of this test, passed to DejaGNU's `pass' and `fail' | |
213 | # commands. If omitted, this defaults to FILE, the root of the | |
214 | # .s and .d files' names. | |
215 | # | |
216 | # as: FLAGS | |
217 | # When assembling FILE.s, pass FLAGS to the assembler. | |
218 | # | |
219 | # PROG: PROGRAM-NAME | |
220 | # The name of the program to run to analyze the .o file produced | |
221 | # by the assembler. This can be omitted; run_dump_test will guess | |
222 | # which program to run by seeing which of the flags options below | |
223 | # is present. | |
224 | # | |
225 | # objdump: FLAGS | |
226 | # nm: FLAGS | |
227 | # objcopy: FLAGS | |
228 | # Use the specified program to analyze the .o file, and pass it | |
229 | # FLAGS, in addition to the .o file name. | |
230 | # | |
231 | # source: SOURCE | |
232 | # Assemble the file SOURCE.s. If omitted, this defaults to FILE.s. | |
233 | # This is useful if several .d files want to share a .s file. | |
234 | # | |
235 | # Each option may occur at most once. | |
236 | # | |
237 | # After the option lines come regexp lines. `run_dump_test' calls | |
238 | # `regexp_diff' to compare the output of the dumping tool against the | |
239 | # regexps in FILE.d. `regexp_diff' is defined later in this file; see | |
240 | # further comments there. | |
