# 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.
