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