# run_dump_test FILE (optional:) EXTRA_OPTIONS
# Copied from gas testsuite, tweaked and further extended.
#
# 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.
#
# 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, 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;
# see further comments there.
