   4 # This test demonstrates "layered" multilib in which more than one
   5 # multilib is matched.
   6 # For example a multilib containing only a no-exceptions libc++ could
   7 # be layered on top of a multilib containing C libs. This avoids the
   8 # need to duplicate the C library for every libc++ variant.
   9 # However -fno-exceptions is not yet supported for multilib selection
  10 # so we use a more contrived -mfloat-abi example instead.
