ic960 and Predefined Macros

Predefined macros within a program can act as constants during execution
or as values in conditional-compilation statements. Predefined macros
include ANSI-standard macros and macros specific to the i960 processor
architecture. The (Undefine) option can remove i960 processor-specific
U
macros but not ANSI-standard macros.
The following macros are available in accordance with the ANSI standard
for C, as described in the book, C: A Reference Manual:
__DATE__ __FILE__
The following macros are predefined by the compilation system when
invoked with the ic960 driver program:
__IC960
