#  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     (score603e_bsp)

#  CONSOLE_USE_INTERRUPTS (score603e_bsp)

#     The score603e console driver has the structure to operate in either

#     polled or interrupt mode.  However both modes only trap to the

#     monitor currently.

#

#  SCORE603E_USE_SDS           (score603e_bsp)

#  SCORE603E_USE_OPEN_FIRMWARE (score603e_bsp)

#  SCORE603E_USE_NONE          (score603e_bsp)

#     The Score603e board can be configured with 3 ROM monitors.  Only two

#     are appropriate for use with RTEMS.  Set exactly one of these to "1"

#     to indicate which ROM monitor is on the board you are using.

#

#  PPC_VECTOR_FILE_BASE (ppc)

#     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.

#

#  PPC_USE_DATA_CACHE (RTEMS PowerPC port)

#     If defined, then the PowerPC specific code in RTEMS will use

#     data cache instructions to optimize the context switch code.

#     This code can conflict with debuggers or emulators.
