-# run_dump_test FILE (optional:) EXTRA_OPTIONS
-# Copied from gas testsuite, tweaked and further extended.
-#
-# Assemble a .s file, then run some utility on it and check the output.
-#
-# There should be an assembly language file named FILE.s in the test
-# suite directory, and a pattern file called FILE.d.  `run_dump_test'
-# will assemble FILE.s, run some tool like `objdump', `objcopy', or
-# `nm' on the .o file to produce textual output, and then analyze that
-# with regexps.  The FILE.d file specifies what program to run, and
-# what to expect in its output.
-#
-# The FILE.d file begins with zero or more option lines, which specify
-# flags to pass to the assembler, the program to run to dump the
-# assembler's output, and the options it wants.  The option lines have
-# the syntax:
-#
-#         # OPTION: VALUE
-#
-# OPTION is the name of some option, like "name" or "objdump", and
-# VALUE is OPTION's value.  The valid options are described below.
-# Whitespace is ignored everywhere, except within VALUE.  The option
-# list ends with the first line that doesn't match the above syntax
-# (hmm, not great for error detection).
-#
-# The optional EXTRA_OPTIONS argument to `run_dump_test' is a list of
-# two-element lists.  The first element of each is an option name, and
-# the second additional arguments to be added on to the end of the
-# option list as given in FILE.d.  (If omitted, no additional options
-# are added.)
-#
-# The interesting options are:
-#
-#   name: TEST-NAME
-#	The name of this test, passed to DejaGNU's `pass' and `fail'
-#       commands.  If omitted, this defaults to FILE, the root of the
-#       .s and .d files' names.
-#
-#   as: FLAGS
-#	When assembling, pass FLAGS to the assembler.
-#       If assembling several files, you can pass different assembler
-#       options in the "source" directives.  See below.
-#
-#   ld: FLAGS
-#       Link assembled files using FLAGS, in the order of the "source"
-#       directives, when using multiple files.
-#
-#   ld_after_inputfiles: FLAGS
-#       Similar to "ld", but put after all input files.
-#
-#   objcopy_objects: FLAGS
-#	Run objcopy with the specified flags after assembling any source
-#	that has the special marker RUN_OBJCOPY in the source specific
-#	flags.
-#
-#   objcopy_linked_file: FLAGS
-#	Run objcopy on the linked file with the specified flags.
-#	This lets you transform the linked file using objcopy, before the
-#	result is analyzed by an analyzer program specified below (which
-#	may in turn *also* be objcopy).
-#
-#   PROG: PROGRAM-NAME
-#       The name of the program to run to analyze the .o file produced
-#       by the assembler or the linker output.  This can be omitted;
-#       run_dump_test will guess which program to run by seeing which of
-#       the flags options below is present.
-#
-#   readelf: FLAGS
-#   objdump: FLAGS
-#   nm: FLAGS
-#   objcopy: FLAGS
-#	Use the specified program to analyze the assembler or linker
-#       output file, and pass it FLAGS, in addition to the output name.
-#	Note that they are run with LC_ALL=C in the environment to give
-#	consistent sorting of symbols.
-#
-#   source: SOURCE [FLAGS]
-#	Assemble the file SOURCE.s using the flags in the "as" directive
-#       and the (optional) FLAGS.  If omitted, the source defaults to
-#       FILE.s.
-#       This is useful if several .d files want to share a .s file.
-#       More than one "source" directive can be given, which is useful
-#       when testing linking.
-#
-#   dump: DUMP
-#	Match against DUMP.d.  If omitted, this defaults to FILE.d.  This
-#	is useful if several .d files differ by options only.  Options are
-#	always read from FILE.d.
-#
-#   xfail: TARGET
-#       The test is expected to fail on TARGET.  This may occur more than
-#       once.
-#
-#   target: TARGET
-#	Only run the test for TARGET.
-#	You may provide target name "cfi" for any target supporting the
-#	CFI statements.  You may provide target name "shared" for any
-#	target supporting shared libraries.  Otherwise TARGET is called
-#	as a TCL procedure if surrounded by square brackets, or passed
-#	to "istarget" if not.
-#	This may occur more than once; the target being tested must match
-#	at least one.  Otherwise the test will be marked unsupported.
-#
-#   alltargets: TARGET
-#	Only run the test for TARGET.
-#	The syntax for TARGET is as with 'target'.
-#	This may occur more than once; the target being tested must match
-#	all of them.  Otherwise the test will be marked unsupported.
-#
-#   notarget: TARGET
-#	Do not run the test for TARGET.
-#	The syntax for TARGET is as with 'target'.
-#	This may occur more than once; the target being tested must not
-#	match any of them.  Otherwise the test will be marked unsupported.
-#
-#   skip: TARGET
-#   anyskip: TARGET
-#   noskip: TARGET
-#	These are exactly the same as "notarget", "alltargets" and
-#	"target" respectively, except that they do nothing at all if the
-#	check fails.  They should only be used in groups, to construct a
-#	single test which is run on all targets but with variant options
-#	or expected output on some targets.  (For example, see
-#	gas/arm/inst.d and gas/arm/wince_inst.d.)
-#
-#   error: REGEX
-#	An error with message matching REGEX must be emitted for the test
-#	to pass.  The PROG, readelf, objdump, nm and objcopy options have
-#	no meaning and need not be supplied if this is present.  Multiple
-#	"error" directives append to the expected linker error message.
-#
-#   error_output: FILE
-#       Means the same as 'error', except the regular expression lines
-#       are contains in FILE.
-#
-#   warning: REGEX
-#	Expect a linker warning matching REGEX.  It is an error to issue
-#	both "error" and "warning".  Multiple "warning" directives
-#	append to the expected linker warning message.
-#
-#   warning_output: FILE
-#       Means the same as 'warning', except the regular expression
-#       lines are contains in FILE.
-#
-#   map: FILE
-#       Adding this option will cause the linker to generate a linker
-#       map file, using the -Map=MAPFILE command line option.  If
-#       there is no -Map=MAPFILE in the 'ld: FLAGS' then one will be
-#       added to the linker command line.  The contents of the
-#       generated MAPFILE are then compared against the regexp lines
-#       in FILE using `regexp_diff' (see below for details).
-#
-# Each option may occur at most once unless otherwise mentioned.
-#
-# After the option lines come regexp lines.  `run_dump_test' calls
-# `regexp_diff' to compare the output of the dumping tool against the
-# regexps in FILE.d.  `regexp_diff' is defined in binutils-common.exp;
-# see further comments there.
