#  NDEBUG (C library)
19
#     if defined asserts do not generate code.  This is commonly used
20
#     as a command line option.

22
#  RTEMS_TEST_NO_PAUSE (RTEMS tests)
23
#     do not pause between screens of output in the rtems tests
24
#
25
#  RTEMS_DEBUG (RTEMS)
26
#     If defined, debug checks in RTEMS and support library code are enabled.
27
#
28
#  PPC_VECTOR_FILE_BASE (ppc)
29
#     This defines the base address of the exception table.
30
#     NOTE: Vectors are actually at 0xFFF00000 but file starts at offset 0x0100
31
#
32
#  PPC_USE_SPRG (RTEMS PowerPC port)
33
#     If defined, then the PowerPC specific code in RTEMS will use some
34
#     of the special purpose registers to slightly optimize interrupt
35
#     response time.  The use of these registers can conflict with
36
#     other tools like debuggers.
37
#
38
#  PPC_USE_DATA_CACHE (RTEMS PowerPC port)
39
#     If defined, then the PowerPC specific code in RTEMS will use
40
#     data cache instructions to optimize the context switch code.
41
#     This code can conflict with debuggers or emulators.
