# 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 in binutils-common.exp;
|
|
# see further comments there.
