Abstract
To perform efficient execution of a bytecode by combining an interpreter and a compiler. At a time of a bytecode execution by an interpreter, if an instruction to be executed is a backward conditional branch instruction, it is determined whether the backward conditional branch instruction is a back edge of a loop. And if it is determined the instruction is a back edge of a loop, the number of the loop iteration is estimated and stored into a storage. A bytecode execution mode is selected according to the estimated number of the loop iteration. This execution mode comprises the modes of immediately compiling a method including a loop, and having the interpreter execute a bytecode.
