Abstract

See full text

Emulation of a guest computer architecture on a host system of another computer architecture. Legacy instructions are translated into translated instructions. If the particular legacy instruction is an operand-setting instruction for storing a value of a precedent operand, a corresponding flag is set when the value of the precedent operand has not been determined. If the particular legacy instruction is an operand-using instruction for using the precedent operand, a check is made to determine if the corresponding flag is set.
