  12 VxWorks Options
  13 ^^^^^^^^^^^^^^^
  14
  15 The options in this section are defined for all VxWorks targets.
  16 Options specific to the target hardware are listed with the other
  17 options for that target.
  18
  19 .. option:: -mrtp
  20
  21   GCC can generate code for both VxWorks kernels and real time processes
  22   (RTPs).  This option switches from the former to the latter.  It also
  23   defines the preprocessor macro ``__RTP__``.
  24
  25 .. option:: -non-static
  26
  27   Link an RTP executable against shared libraries rather than static
  28   libraries.  The options :option:`-static` and :option:`-shared` can
  29   also be used for RTPs (see :ref:`link-options`); :option:`-static`
  30   is the default.
  31
  32 .. option:: -Bstatic, -Bdynamic
  33
  34   These options are passed down to the linker.  They are defined for
  35   compatibility with Diab.
  36
  37 .. option:: -Xbind-lazy
  38
  39   Enable lazy binding of function calls.  This option is equivalent to
  40   :option:`-Wl,-z,now` and is defined for compatibility with Diab.
  41
  42 .. option:: -Xbind-now
  43
  44   Disable lazy binding of function calls.  This option is the default and
  45   is defined for compatibility with Diab.
