+# `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 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_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.
+#
+# 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.
+#
+# xfail: TARGET
+# The test is expected to fail on TARGET. This may occur more than
+# once.
+#
+# target: TARGET
+# Only run the test for TARGET. This may occur more than once; the
+# target being tested must match at least one. You may provide target
+# name "cfi" for any target supporting the CFI statements.
+#
+# notarget: TARGET
+# Do not run the test for TARGET. This may occur more than once;
+# the target being tested must not match any of them.
+#
+# 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. Multiple "error"
+# directives append to the expected linker error message.
+#
+# 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.
+#
+# 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;
