# 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.
|
||||
#
|
||||
# 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.
|
||||
#
|
||||
# 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.
|
||||
#
|
||||
# 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.
