Instruction::mayWriteToMemory() -- is there a logical equivalent for reads?

The Instruction::mayWriteToMemory() member function is quite useful (I'm currently writing code that will break up basic blocks at read/write instructions). Is there a safe way to do the same thing for reads from memory? It's easy enough to check for the relevant instructions, but I thought this might be a nice-to-have in a future version because it separates code like mine from needing to know too much about the instructions it is manipulating (which is a good thing from a future portability point of view, as well as being logically cleaner).

Yep, the alias analysis interface will provide this information for you,
