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 neccessary information OpenOCD needs to provide support
7 * in the most robust manner possible.
9 * This file should be linked along with the project to enable RTOS
10 * support for uC/OS-III.
