# This is the actual bsp directory used during the build process.
RTEMS_BSP_FAMILY=ts_386ex

#  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.
#
CPU_CFLAGS =-msoft-float -mno-fp-ret-in-387

# optimize flag: typically -0, could use -O4 or -fast
# -O4 is ok for RTEMS
# -fomit-frame-pointer breaks debugging and C++ exceptions
CFLAGS_OPTIMIZE_V= -O4 

#  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.
