The PowerPC Architecture: A specification for a new family of RISC processors

Larry's probably thinking of the "with update" family of instructions, e.g.:

<quote>
Load Doubleword with Update Indexed  X-form

  ldux    RT,RA,RB

EA <- (RA) + (RB)
RT <- MEM(EA, 8)
RA <- EA

Let the effective address (EA) be the sum (RA)+(RB).  The doubleword in storage 
addressed by EA is loaded into RT.

EA is placed into register RA.

If RA=0 or RA=RT, the instruction form is invalid.

This instruction is defined only for 64-bit implementations.  Using it on a 
32-bit implementation will cause the system illegal instruction error handler 
to be invoked.
