# run_dump_test FILE (optional:) EXTRA_OPTIONS
#
# 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.
# However, a line within the options that begins with a #, but doesn't
# have a recognizable option name followed by a colon, is considered a
# comment and entirely ignored.
#
# 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 FILE.s, pass FLAGS to the assembler.
#
#   PROG: PROGRAM-NAME
#       The name of the program to run to modify or analyze the .o file
#       produced by the assembler.  This option is required.  Recognised
#       names are: ar, elfedit, nm, objcopy, ranlib, strings, and strip.
#
#   DUMPPROG: PROGRAM-NAME
#       The name of the program to run to analyze the .o file after it has
#       has been modified by PROG.  This can be omitted; run_dump_test will
#       guess which program to run by seeing if any of the flags options
#       for the recognised dump programs are set.  Recognised names are:
#       addr2line, nm, objdump, readelf and size.
#
#   nm: FLAGS
#   objcopy: FLAGS
#   objdump: FLAGS
#   readelf: FLAGS
#   size: FLAGS
#	Use the specified program to analyze the .o file, and pass it
#	FLAGS, in addition to the .o file name.  Note that they are run
#	with LC_ALL=C in the environment to give consistent sorting
#	of symbols.
#
#   source: SOURCE
#	Assemble the file SOURCE.s.  If omitted, this defaults to FILE.s.
#       This is useful if several .d files want to share a .s file.
#
#   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.
#
#   target: GLOBS...
#       Run this test only on a specified list of targets.  More precisely,
#       each glob in the space-separated list is passed to "istarget"; if
#       it evaluates true for any of them, the test will be run, otherwise
#       it will be marked unsupported.
#
#   not-target: GLOBS...
#       Do not run this test on a specified list of targets.  Again,
#       the each glob in the space-separated list is passed to
#       "istarget", and the test is run if it evaluates *false* for
#       *all* of them.  Otherwise it will be marked unsupported.
#
#   skip: GLOBS...
#   not-skip: GLOBS...
#       These are exactly the same as "not-target" 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, objdump, nm and objcopy options have no
#	meaning and need not supplied if this is present.
#
#   warning: REGEX
#	Expect a gas warning matching REGEX.  It is an error to issue
#	both "error" and "warning".
#
#   stderr: FILE
#       FILE contains regexp lines to be matched against the diagnostic
#       output of the assembler.  This does not preclude the use of
#       PROG, nm, objdump, or objcopy.
#
#   error-output: FILE
#       Means the same as 'stderr', but also indicates that the assembler
#       is expected to exit unsuccessfully (therefore PROG, objdump, nm,
#       and objcopy have no meaning and should not be supplied).
#
# Each option may occur at most once.
#
# 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.

	153	# There should be an assembly language file named FILE.s in the test

	159	#
	160	# The FILE.d file begins with zero or more option lines, which specify

	170	# list ends with the first line that doesn't match the above syntax.
	171	# However, a line within the options that begins with a #, but doesn't
	172	# have a recognizable option name followed by a colon, is considered a
	173	# comment and entirely ignored.
	174	#
	175	# The optional EXTRA_OPTIONS argument to `run_dump_test' is a list of
