# 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.
|
|
#
|
|
# 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.
|
|
#
|
|
# 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.
|
|
#
|
|
# warning: REGEX
|
|
# Expect a linker warning matching REGEX. It is an error to issue
|
|
# both "error" and "warning".
|
|
#
|
|
# 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.
