#
# 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, optionally run objcopy on the object file,
# optionally run ld, optionally run another objcopy, optionally run
# another tool under test specified by PROG, then run a dump tool like
# addr2line, nm, objdump, readelf or size on the object 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, pass FLAGS to the assembler.
# If assembling several files, you can pass different assembler
# options in the "source" directives. See below.
# Multiple instances of this directive tells run_dump_test to run the test
# multiple times -- one time with each set of flags provided.
# Each instance will run exactly as a file with a single "as" line, it is
# not possible to condition any behaviour on which set of "as" flags is
# used. That means that the "source" specific options are appended to
# the "as" flags for their corresponding files, and any extra processing
# (e.g. with "ld" and "objcopy") is repeated for each test.
#
# 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 FLAGS after all input files.
#
# cc: FLAGS
# Run the compiler with FLAGS (to which -S is added) to generate assembler
# source first. source: must be provided and should consist of .c files.
# Source-specific CC flags are not supported.
#
# 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.
#
# PROG: PROGRAM-NAME
# The name of a program under test, to run to modify or analyze the
# .o file produced by the assembler. Recognised names are: ar,
# elfedit, nm, objcopy, ranlib, strings, and strip.
#
# DUMPPROG: PROGRAM-NAME
# The name of the program to run to analyze the file produced
# by the assembler or the linker. This can be omitted;
# run_dump_test will guess which program to run from which of
# the flags options below is present.
#
# addr2line: FLAGS
# nm: FLAGS
# objdump: FLAGS
# readelf: FLAGS
# size: FLAGS
# Use the specified program to analyze the 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. If no FLAGS are needed then you can use:
# DUMPPROG: [nm objdump readelf addr2line]
# instead, or just pass a flag that happens to be the default.
# If objdump is the dump tool and we're not dumping binary, nor
# have run ld, then the standard section names (.text, .data and
# .bss) are replaced by target ones if any (eg. rx-elf uses "P"
# instead of .text). The substition is done for both the
# objdump options (eg: "-j .text" is replaced by "-j P") and the
# reference file.
#
# 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.
#
# target: GLOB|PROC ...
# Run this test only on a specified list of targets. More precisely,
# in the space-separated list each glob is passed to "istarget" and
# each proc is called as a TCL procedure. List items are interpreted
# such that procs are denoted by surrounding square brackets, and any
# other items are consired globs. If the call evaluates true for any
# of them, the test will be run, otherwise it will be marked
# unsupported.
#
# notarget: GLOB|PROC ...
# Do not run this test on a specified list of targets. Again, each
# glob in the space-separated list is passed to "istarget" and each
# proc is called as a TCL procedure, and the test is run if it
# evaluates *false* for *all* of them. Otherwise it will be marked
# unsupported.
#
# alltargets: GLOB|PROC ...
# Run this test on a specified list of targets. Again, each
# glob in the space-separated list is passed to "istarget" and each
# proc is called as a TCL procedure, and the test is run if it
# evaluates *true* for *all* of them. Otherwise it will be marked
# unsupported.
#
# skip: GLOB|PROC ...
# anyskip: GLOB|PROC ...
# noskip: GLOB|PROC ...
# These are exactly the same as "notarget", "alltargets" 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.)
#
# xfail: GLOB|PROC ...
# Run this test and it is is expected to fail on a specified list
# of targets.
#
# error: REGEX
# An error with message matching REGEX must be emitted for the test
# to pass. The DUMPPROG, addr2line, nm, objdump, readelf and size
# options have no meaning and need not supplied if this is present.
# Multiple "error" directives append to the expected error message.
#
# error_output: FILE
# Means the same as 'error', except the regular expression lines
# are contains in FILE.
#
# warning: REGEX
# Expect a warning matching REGEX. It is an error to issue
# both "error" and "warning". Multiple "warning" directives
# append to the expected 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).
#
# section_subst: no
# Means that the section substitution for objdump is disabled.
#
# 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.
