#  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
#
#  STACK_CHECKER_ON (RTEMS support code)
#     If defined, stack bounds checking is enabled.
#
#  STACK_CHECKER_REPORT_USAGE (RTEMS support code)
#     If this and STACK_CHECKER_ON are defined, then a report on stack usage
#     per task is printed when the program exits.
#
#  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_ABI (ppc)
#     This defines the calling convention (Application Binary Interface)
#     used in this configuration.  EABI is the only one supported.
#
#  PPC_ASM (ppc)
#     This defines the assembly language format used in this configuration.
#     ELF is the only one supported.
#
#  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.
