17
18 * compile.c (decode): Enhancements for mova.
19 Initialize cst, reg, and rdisp inside the loop, for each
20 new instruction. Defer correction of the disp2 values until
21 later, and then adjust them by the size of the first operand,
22 rather than the size of the instruction.
23 (sim_resume): For mova, adjust the size of the second operand
24 according to the type of the first operand (INDEXB vs. INDEXW).
25 In cases where there is only one operand, the other two must
26 both be composed on the fly.
