20#  NDEBUG (C library)
21#     if defined asserts do not generate code.  This is commonly used
22#     as a command line option.
23#
24#  RTEMS_TEST_NO_PAUSE (RTEMS tests)
25#     do not pause between screens of output in the rtems tests
26#
27#  RTEMS_DEBUG (RTEMS)
28#     If defined, debug checks in RTEMS and support library code are enabled.
29#       
30#  PPC_VECTOR_FILE_BASE (PowerPC)
31#     This defines the base address of the exception table.
32#     NOTE: Vectors are actually at 0xFFF00000 but file starts at offset 0x0100
33#       
34#  PPC_ABI (PowerPC)
35#     This defines the calling convention (Application Binary Interface)
36#     used in this configuration.  EABI is the only one supported.
37#     This BSP was initially developed using the PowerOpen ABI.
38#
39#  PPC_ASM (PowerPC)
40#     This defines the assembly language format used in this configuration.
41#     ELF is the only one supported.
42#
43#  PPC_USE_SPRG (RTEMS PowerPC port)
44#     If defined (=1), then the PowerPC specific code in RTEMS will use some
45#     of the special purpose registers to slightly optimize interrupt
46#     response time.  The use of these registers can conflict with
47#     other tools like debuggers.
