Last change on this file since d102375e was d102375e, checked in by Joel Sherrill <joel.sherrill@…>, on May 28, 2000 at 5:52:30 PM

Removed definition of PPC_ABI and PPC_ASM as there are now defaults
that reflect the GNU toolset.

18#  NDEBUG (C library)
19#     if defined asserts do not generate code.  This is commonly used
20#     as a command line option.
21#
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.
