// FIXME: This implementation works under the assumption that load/store queue
// entries are reserved at 'instruction dispatched' stage, and released at
// 'instruction executed' stage. This currently matches the behavior of LSUnit.
//
// The current design minimizes the number of events generated by the
// Dispatch/Execute stages, at the cost of doing extra bookkeeping in method
// `onEvent`. However, it introduces a subtle dependency between this view and
// how the LSUnit works.
//
// In future we should add a new "memory queue" event type, so that we stop
// making assumptions on how LSUnit internally works (See PR39828).
