   1 /*
   2  * uC/OS-III does not provide a fixed layout for OS_TCB, which makes it
   3  * impossible to determine the appropriate offsets within the structure
   4  * unaided. A priori knowledge of offsets based on os_dbg.c is tied to a
   5  * specific release and thusly, brittle. The constants defined below
   6  * provide the necessary information OpenOCD needs to provide support in
   7  * the most robust manner possible.
   8  *
   9  * This file should be linked along with the project to enable RTOS
  10  * support for uC/OS-III.
