# 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. |
# 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 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. Note that they are run |
# with LC_ALL=C in the environment to give consistent sorting |
# of symbols. |
# |
# 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. |
# |
# target: GLOBS... |
# Run this test only on a specified list of targets. More precisely, |
# each glob in the space-separated list is passed to "istarget"; if |
# it evaluates true for any of them, the test will be run, otherwise |
# it will be marked unsupported. |
# |
# not-target: GLOBS... |
# Do not run this test on a specified list of targets. Again, |
# the each glob in the space-separated list is passed to |
# "istarget", and the test is run if it evaluates *false* for |
# *all* of them. Otherwise it will be marked unsupported. |
# |
# skip: GLOBS... |
# not-skip: GLOBS... |
# These are exactly the same as "not-target" 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.) |
# |
# 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. |
# |
# warning: REGEX |
# Expect a gas warning matching REGEX. It is an error to issue |
# both "error" and "warning". |
# |
# stderr: FILE |
# FILE contains regexp lines to be matched against the diagnostic |
# output of the assembler. This does not preclude the use of |
# PROG, nm, objdump, or objcopy. |
# |
# error-output: FILE |
# Means the same as 'stderr', but also indicates that the assembler |
# is expected to exit unsuccessfully (therefore PROG, objdump, nm, |
# and objcopy have no meaning and should not be supplied). |
# |
# 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. |
