Hmm? The original expression is an address, I have to build a MEM_REF out of that, and the is_gimple_mem_ref_addr() just checked that that very address (after going through fold) is not acceptable as MEM_REF operand. So how could I avoid the massaging of the address to make it an acceptable operand? Ciao, Michael.
