/*
 * 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 neccessary 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.
