UCOS II源码 内含SOURCE 解压后使用

/* 
**
**	Created by Andre Gompel for uCOS-II port to Tricore
**	10/99 Updated for TC10GP
**	The same file is used for assembly and C
** Each register is described in 3 places:
**		C definition: as a C type and as an equate for asm statments from C
**	   	(work around C preprocessor discrepancy)
**		Assembly equate.
