If the signedness doesn't matter for the operation, it won't generally be encoded in the operator. But, in this case, further processing of the operation shouldn't have to care about signedness, since at some point it didn't matter. On the other hand, if you're talking about the initial processing (i.e. during RTL expansion), the information is encoded in the trees fed to the expander. -- Eric Botcazou
