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

#  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.

#

#

#  PPC_VECTOR_FILE_BASE (PowerPC)

#     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.
