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