When each load or store is sent to the LSQ, we check whether it will cross a cache line boundary and, if so, split it in two. This creates two TLB translations and two memory requests. Care has to be taken if the first packet of a split load is sent but the second blocks the cache. Similarly, for a store, if the first packet cannot be sent, we must store the second one somewhere to retry later. This modifies the LSQSenderState class to record both packets in a split load or store. Finally, a new const variable, HasUnalignedMemAcc, is added to each ISA to indicate whether unaligned memory accesses are allowed. This is used throughout the changed code so that compiler can optimise away code dealing with split requests for ISAs that don't need them. |
