     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.
