METHOD/DEVICE FOR COMPILING AND METHOD/DEVICE FOR CALCULATING METHOD ACTIVITY DEGREE

Japanese Patent JP3807860

B2

PROBLEM TO BE SOLVED: To provide a method for calculating a method activity degree for effectively selecting a method for destructing a code.
SOLUTION: In compiling, a calling map concerning method calling which can be generated in the method is prepared and stored in a storing device, and a code for recording method calling generated actually is generated and stored in the storing device. In recovering the code in a state like this, all the threads are temporarily stopped to calculate activity degree expressing high or low possibility that some method is to be executed. Through the use of the calling map and information concerning method calling generated actually concerning a first method corresponding to a stuck frame, a second method of high possibility of being called from the first method is specified and stored in the storing device and priority according to the number of stages from the highest part of the stuck of the stuck frame corresponding to the first method is operated to the activity degree of the second method to update the activity degree of the second method. It is suitable to repeat processing like this. After then, the code of a method of a low activity degree is destructed.
