There are a number of users of spriv-opt that are hitting errors because of stores with different types. In general, this is wrong, but, in these cases, the types are the exact same except for decorations. The options is "--relax-store-struct", and it can be used with the validator or the optimizer. We assume that if layout information is missing it is consistent. For example if one struct has a offset of one of its members, and the other one does not, we will still consider them as being layout compatible. The problem will be if both struct has and offset decoration for corresponding members, and the offset are different.
