Memory is not simple any more.  You must precisely define what is a read
and what is a write.  For example, what is a cache hit (level 1 [L1])?
An L2 hit?  L3?  Coalesced consecutive writes?

If what you count is architectural read/write to data, then disassemble
enough to recognize instructions and basic blocks.  Modify the code
in-place to increment a counter at the end of every basic block.
