--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
    taskInfo.ready[priority]->wakeTime = Task_enforceTimeslice(priority);

This is the same as:
    (*taskInfo.ready[priority]).wakeTime = Task_enforceTimeslice(priority);

Which means either the compiler can read the value of taskInfo.ready[priority]
before or after the function call to Task_enforceTimeslice because there is no
sequence point between them.
