Users can +specify flags ``-lqueue`` and ``-squeue`` to limit the number of entries in the +load and store queues respectively. The queues are unbounded by default. + +The LSUnit implements a relaxed consistency model for memory loads and stores. +The rules are: + +1. A younger load is allowed to pass an older load only if there are no + intervening stores or barriers between the two loads. +2. A younger load is allowed to pass an older store provided that the load does + not alias with the store. +3. A younger store is not allowed to pass an older store. +4. A younger store is not allowed to pass an older load. + +By default, the LSUnit optimistically assumes that loads do not alias +(`-noalias=true`) store operations. Under this assumption, younger loads are +always allowed to pass older stores. Essentially, the LSUnit does not attempt +to run any alias analysis to predict when loads and stores do not alias with +each other. + +Note that, in the case of write-combining memory, rule 3 could be relaxed to +allow reordering of non-aliasing store operations. That being said, at the +moment, there is no way to further relax the memory model (``-noalias`` is the +only option). Essentially, there is no option to specify a different memory +type (e.g., write-back, write-combining, write-through; etc.) and consequently +to weaken, or strengthen, the memory model. + +Other limitations are: + +* The LSUnit does not know when store-to-load forwarding may occur. +* The LSUnit does not know anything about cache hierarchy and memory types. +* The LSUnit does not know how to identify serializing operations and memory + fences. + +The LSUnit does not attempt to predict if a load or store hits or misses the L1 +cache. It only knows if an instruction "MayLoad" and/or "MayStore." For +loads, the scheduling model provides an "optimistic" load-to-use latency (which +usually matches the load-to-use latency for when there is a hit in the L1D). + +:program:`llvm-mca` does not know about serializing operations or memory-barrier +like instructions. The LSUnit conservatively assumes that an instruction which +has both "MayLoad" and unmodeled side effects behaves like a "soft" +load-barrier. That means, it serializes loads without forcing a flush of the +load queue. Similarly, instructions that "MayStore" and have unmodeled side +effects are treated like store barriers. A full memory barrier is a "MayLoad" +and "MayStore" instruction with unmodeled side effects. This is inaccurate, but +it is the best that we can do at the moment with the current information +available in LLVM. + +A load/store barrier consumes one entry of the load/store queue. A load/store +barrier enforces ordering of loads/stores. A younger load cannot pass a load +barrier. Also, a younger store cannot pass a store barrier. A younger load +has to wait for the memory/load barrier to execute. A load/store barrier is +"executed" when it becomes the oldest entry in the load/store queue(s). That +also means, by construction, all of the older loads/stores have been executed. + +In conclusion, the full set of load/store consistency rules are: + +#. A store may not pass a previous store. +#. A store may not pass a previous load (regardless of ``-noalias``). +#. A store has to wait until an older store barrier is fully executed. +#. A load may pass a previous load. +#. A load may not pass a previous store unless ``-noalias`` is set. +#. A load has to wait until an older load barrier is fully executed.
