# run_dump_test FILE 
#
# 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 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.
#
#   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.
#
# 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.

190	# There should be an assembly language file named FILE.s in the test
191	# suite directory, and a pattern file called FILE.d. `run_dump_test'
192	# will assemble FILE.s, run some tool like `objdump', `objcopy', or
193	# `nm' on the .o file to produce textual output, and then analyze that
194	# with regexps. The FILE.d file specifies what program to run, and
195	# what to expect in its output.
196	#
197	# The FILE.d file begins with zero or more option lines, which specify
198	# flags to pass to the assembler, the program to run to dump the
199	# assembler's output, and the options it wants. The option lines have
200	# the syntax:
201	#
202	# # OPTION: VALUE
203	#
204	# OPTION is the name of some option, like "name" or "objdump", and
205	# VALUE is OPTION's value. The valid options are described below.
206	# Whitespace is ignored everywhere, except within VALUE. The option
207	# list ends with the first line that doesn't match the above syntax
208	# (hmm, not great for error detection).
209	#
210	# The interesting options are:
211	#
212	# name: TEST-NAME
213	# The name of this test, passed to DejaGNU's `pass' and `fail'
214	# commands. If omitted, this defaults to FILE, the root of the
215	# .s and .d files' names.
216	#
217	# as: FLAGS
218	# When assembling FILE.s, pass FLAGS to the assembler.
219	#
220	# PROG: PROGRAM-NAME
221	# The name of the program to run to analyze the .o file produced
222	# by the assembler. This can be omitted; run_dump_test will guess
223	# which program to run by seeing which of the flags options below
224	# is present.
225	#
226	# objdump: FLAGS
227	# nm: FLAGS
228	# objcopy: FLAGS
229	# Use the specified program to analyze the .o file, and pass it
230	# FLAGS, in addition to the .o file name.
231	#
232	# source: SOURCE
233	# Assemble the file SOURCE.s. If omitted, this defaults to FILE.s.
234	# This is useful if several .d files want to share a .s file.
235	#
236	# Each option may occur at most once.
237	#
238	# After the option lines come regexp lines. `run_dump_test' calls
239	# `regexp_diff' to compare the output of the dumping tool against the
240	# regexps in FILE.d. `regexp_diff' is defined later in this file; see
