Method of compiling a program

A method of compiling an updated program having a plurality of updated functions that is updated from an original program having a plurality of original functions, the method comprising:

• performing machine learning for optimization combinations according to function features of the plurality of original functions of the original program;
• determining whether a first original function among the plurality of original functions corresponding to a first updated function among the plurality of updated functions exists;
• obtaining a first optimization combination according to a function feature of the first updated function by using a result of the machine learning when the first original function does not exist;
• determining whether the first updated function is changed from the first original function when the first original function exists;
• reading a second optimization combination applied to the first original function from a configuration database storing optimization combinations for the plurality of original functions, when the first updated function is not changed from the first original function;
• generating a third optimization combination for the first updated function by reflecting a fourth optimization combination obtained using the result of the machine learning and a fifth optimization combination applied to the first original function with a change ratio of a function feature of the first updated function to a function feature of the first original function, when the first updated function is changed from the first original function;
• and
• compiling the updated program using the first optimization combination, the second optimization combination, or the third optimization combination.

A method of compiling an updated program having a plurality of updated functions that is updated from an original program having a plurality of original functions, the method comprising:

• obtaining an optimization configuration including optimization combinations of the plurality of original functions by performing iterative compilation for each of the plurality of original functions of the original program;
• storing the optimization configuration in a configuration database;
• determining whether a first original function among the plurality of original functions corresponding to a first updated function among the plurality of updated functions exists and whether the first updated function is changed from the first original function;
• reading a first optimization combination applied to the first original function, among the optimization combinations included in the optimization configuration, from the configuration database, when the first original function exists and the first updated function is not changed from the first original function;
• and
• compiling the updated program using the read first optimization combination.
