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