30# run_link_test FILE
31# Copied from run_dump_test, with the dumping part removed.
32#
33# Assemble a .s file, then run some utility on it and check the output.
34#
35# There should be an assembly language file named FILE.s in the test
36# suite directory.  `run_link_test' will assemble and link FILE.s
37#
38# The FILE.lt file begins with zero or more option lines, which specify
39# flags to pass to the assembler, the program to run to dump the
40# assembler's output, and the options it wants.  The option lines have
41# the syntax:
42#
43#         # OPTION: VALUE
44#
45# OPTION is the name of some option, like "name" or "ld", and
46# VALUE is OPTION's value.  The valid options are described below.
47# Whitespace is ignored everywhere, except within VALUE.  The option
48# list ends with the first line that doesn't match the above syntax
49# (hmm, not great for error detection).
50#
51# The interesting options are:
52#
53#   name: TEST-NAME
54#	The name of this test, passed to DejaGNU's `pass' and `fail'
55#       commands.  If omitted, this defaults to FILE, the root of the
56#       .s and .d files' names.
57#
58#   as: FLAGS
59#	When assembling, pass FLAGS to the assembler.
60#       If assembling several files, you can pass different assembler
61#       options in the "source" directives.  See below.
62#
63#   ld: FLAGS
64#       Link assembled files using FLAGS, in the order of the "source"
65#       directives, when using multiple files.
66#
67#   source: SOURCE [FLAGS]
68#	Assemble the file SOURCE.s using the flags in the "as" directive
69#       and the (optional) FLAGS.  If omitted, the source defaults to
70#       FILE.s.
71#       This is useful if several .x files want to share a .s file.
72#       More than one "source" directive can be given, which is useful
73#       when testing linking.
74#
75#   xfail: TARGET
76#       The test is expected to fail on TARGET.  This may occur more than
77#       once.
78#
79#   target: TARGET
80#       Only run the test for TARGET.  This may occur more than once; the
81#       target being tested must match at least one.
82#
83#   notarget: TARGET
84#       Do not run the test for TARGET.  This may occur more than once;
85#       the target being tested must not match any of them.
86#
87# Each option may occur at most once unless otherwise mentioned.
