| It is possible to allow an assember to rearrange code for optimization.

And in fact on systems that use the MIPS chips (MIPSco, SGI,
DECstation), the assemblers already do this, primarily to fill delay
slots and such.  If I really need to know about what the assembler did
behind my back, I have to disassemble the object module.
