Compiling method and processor using the same

A non-transitory computer-readable storage medium storing a program to implement a compiling method, the program comprising instructions to cause a computer to:

• simulate program code which includes at least one first operation command to generate a first operation result;
• translate the program code into machine code of a processor that comprises at least one second operation command;
• simulate the machine code to generate a second operation result;
• and
• compare the first operation result with the second operation result to verify whether the machine code is valid, wherein:
• the translating of the program code comprises register-allocating the program code, and
• the simulating of the program code comprises simulating the program code by referring to stack information of the machine code, which is generated after the program code is register-allocated.

A processor comprising:

• a code transformer configured to translate program code which includes at least one first operation command into machine code of a computer comprising at least one second operation command;
• a first simulator configured to simulate the program code to generate a first operation result;
• and
• a second simulator configured to simulate the machine code to generate a second operation result, wherein:
• the processor verifies whether the machine code is valid by comparing the first operation result and the second operation result,
• the code transformer register-allocates the program code and transmits stack information of the machine code, which is generated after the program code is register-allocated, and
• the first simulator simulates the program code by referring to the stack information.
