-# This proc requires two input files -- the .s file containing the

-proc run_dump_test { name } {
+# 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 analyze the .o file produced
+# by the assembler. This can be omitted; run_dump_test will guess
+# which program to run by seeing which of the flags options below
+# is present.
+#
+# objdump: FLAGS
+# nm: FLAGS
+# objcopy: 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.
+#
+# 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 later in this file; see
+# further comments there.
