#  This section makes the target dependent options file.

#  NDEBUG (C library)
#     if defined asserts do not generate code.  This is commonly used
#     as a command line option.
#
#  RTEMS_TEST_NO_PAUSE (RTEMS tests)
#     do not pause between screens of output in the rtems tests
#
#  RTEMS_DEBUG (RTEMS)
#     If defined, debug checks in RTEMS and support library code are enabled.
#
#  CONSOLE_USE_POLLED     (mvme2307_bsp)
#  CONSOLE_USE_INTERRUPTS (mvme2307_bsp)
#     The mvme2307 console driver has the structure to operate in either
#     polled or interrupt mode.  However both modes only trap to the
#     monitor currently.
#
#  PPC_VECTOR_FILE_BASE (PowerPC)
#     This defines the base address of the exception table.
#     NOTE: Vectors are actually at 0xFFF00000 but file starts at offset 0x0100
#
#  PPC_USE_SPRG (RTEMS PowerPC port)
#     If defined, then the PowerPC specific code in RTEMS will use some
#     of the special purpose registers to slightly optimize interrupt
#     response time.  The use of these registers can conflict with 
#     other tools like debuggers.
