Michael Snyder f408565cc8 2003-07-18 Michael Snyder <msnyder@redhat.com> 
* compile.c (decode): Enhancements for mova.
        Initialize cst, reg, and rdisp inside the loop, for each
        new instruction.  Defer correction of the disp2 values until
        later, and then adjust them by the size of the first operand,
        rather than the size of the instruction.
        (sim_resume): For mova, adjust the size of the second operand
        according to the type of the first operand (INDEXB vs. INDEXW).
        In cases where there is only one operand, the other two must
        both be composed on the fly.
