The Ruby banked array resource checks (initiated from SLICC) did a check and allocate at the same time. If a transition needs more than one resource, then it might check/allocate resource #1, then fail to get resource #2. Another transition might then try to get the same resources, but in reverse order. Deadlock. This patch separates resource checking and resource reservation into two steps to avoid deadlock. |
