return code, when success with no message is expected, don't continue if we have an abnormal exit with a message. Check output of inspection program and fail if it had output or an abnormal exit code. Include "warning" and "error" among the directives where multiples are allowed and append to previous values.

# run_dump_test FILE

# 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 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_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.
|
|
#
|
|
# 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 later in this file; see
|
|
# further comments there.
