* other definitions for the XTENSA processors family 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.
