* other definitions for the Nios II processor architecture. |
|

|
* This file is also included by assembly language files which must #define |
|
* _ASMLANGUAGE before including this header file. Note that kernel |
|
* assembly source files obtains structure offset values via "absolute |
|
* symbols" in the offsets.o module. |
