// =======================================================================
// TODO
// What are the rules
// A) ON LOAD MISS
// 1) it can only be sent if there are no unresolved stores in front of it, and there are no store collisions ahead of it
// 2)
// B) ON LOAD HIT
// 1) it can only be sent if there are no unresolved stores or loads in front of it and there are no collisions.
// 2) if there are outstanding unresolved stores, the load must be marked to be checked when all stores are resolved
// if there ends up being a collision, a flush needs to be issued for the load.
// 3)
// C) ON STORE
// 1) stores can be sent as long as all ops ahead are resolved and there are no collisions
// 2)
//
// NOTE: The odq_ldq_send_cmd signal is generatated from the following logic. The way flushes work currently
// I don't have an indicator that an entry has been completed. If we have an old itag that matches a new
// itag that gets flushed, the old itag's flushed indicator will come on to ldq. This could be fixed by
// getting completion results from ldq and storing them and gating cp_flush for the entry if it is considered
// completed by the ldq.
// Instead of adding this logic we decided to allow the flush to come on for the old itag and we do not gate off
// cmd_send for the entry. The command send will get gated off for the myflush and early_flush indicators
// so ldq can qualify next itag to complete.

// is entry 0 and just doing a full shift of all entries.
// 3. prevent removal of entries > 0 concurrent with the update of the entry from the ldq.
//
// For now I am choosing option 3 at it will be the best timing and still gets most of the benefit from removing the flushed entries
