75 * Note that insn at 0x211 is 2-byte cond jump insn for offset 0x7d (-125)

88 * Note that insn at 0x211 is 6-byte cond jump insn now since its offset
89 * becomes 0x80 based on previous round (0x293 - 0x213 = 0x80).
90 * At the same time, insn at 0x292 is a 2-byte insn since its offset is
97 * cycle in the above. In the above example je offset <= 0x7c should work.
99 * For other cases, je <-> je needs offset <= 0x7b to avoid no convergence
100 * issue. For jmp <-> je and jmp <-> jmp cases, jmp offset <= 0x7c should
104 * to maximum 123 (0x7b). This way, the jit pass can eventually converge.
