# run_link_test FILE 
# Copied from run_dump_test, with the dumping part removed.
#
# 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.  `run_link_test' will assemble and link FILE.s 
#
# The FILE.lt 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 "ld", 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.
#
#   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 .x 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.
#
# Each option may occur at most once unless otherwise mentioned.
