I must confess I am not too familiar with how the various CPUs accomplish this. Hopefully someone else is able to help.

In gem5, strd in divided into multiple micro instructions, each writing four bytes of data. A younger ldrd might have to get the data directly from two micro store instruction. It will be really helpful if you can provide some pointers on how ldrd is able to get the date from the older strd micro instructions in gem5.
