# This contains the compiler options necessary to select the CPU model
# and (hopefully) optimize for it. Enables software floating-point
# emulation since we don't have a i387 co-processor.

# 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.
