Method and the device in order to process the exception which is in the midst of program code conversion accurately

摘要

The accurate except operation which depends on in an accurate object state where accurate program counter value and register value of the object processor are included. The object cord/code (17), the feasibility target cord/code (21) it is converted the target processor (13) by. The goal order which the target cord/code which is formed (17), the object cord/code order which is easy to receive obstacle (174) it is related, corresponds (214) it includes. Furthermore, the goal cord/code order which corresponds (214) each is attached information of recovery (195) relation. For example exception (when obstacle) occurs, although information of the recovery (195) is removed, the target cord/code especially of the general case (21) inserts the optimization which is formed in consideration, recovers accurate object state information of particular recovery (195) is used. Next, using the accurate object state, exception is processed accurately.
