*1 The number of branch instructions is a total of the following pointer branch instructions and structure creation
instructions, which are executed between a start point and an end point of the scan time measurement.
• Pointer branch instructions: CJ, SCJ, JMP, GOEND
• Structure creation instruction: CALL(P), FCALL(P), ECALL(P), EFCALL(P), XCALL(P), BREAK, NEXT, RET
