Try to use accumulator to move value to register #111

Open GoogleCodeExporter opened 9 years ago

In loop optimization, we currently expect it is possible to move the value of 
optimized variable to a register using single CPU instruction.
It must not be possible (for example on Z80).

Try to use some selected register (accumulator) to perform the move in two 
instructions:

::::::::::::::::
let ACC, %A
let %R, ACC
::::::::::::::::

We may use temporary variable to save the value of ACC.
