 187 #
 188 # Assemble a .s file, then run some utility on it and check the output.
 189 #
 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.
 196 #
 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
 200 # the syntax:
 201 #
 202 #         # OPTION: VALUE
 203 #
 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).
 209 #
 210 # The interesting options are:
 211 #
 212 #   name: TEST-NAME
 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.
 216 #
 217 #   as: FLAGS
 218 #       When assembling FILE.s, pass FLAGS to the assembler.
 219 #
 220 #   PROG: PROGRAM-NAME
 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
 224 #       is present.
 225 #
 226 #   objdump: FLAGS
 227 #   nm: FLAGS
 228 #   objcopy: FLAGS
 229 #       Use the specified program to analyze the .o file, and pass it
 230 #       FLAGS, in addition to the .o file name.
 231 #
 232 #   source: SOURCE
 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.
 235 #
 236 # Each option may occur at most once.
 237 #
 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.
