|
# # 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.
|
|
#
|
|
# 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.
