#  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.
#
#  BSP_DEBUG (BSP)
#     Enables some debugging in the BSP package.
#
#  LOAD_RTC_AT_START (BSP)
#     Initialize RTC and load into system clock at startup. This will break
#     some tests.
