-# 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
-# (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. 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, 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.
