JCC指令

JZ/JE 若为0则跳转；若相等则跳转 jump if zero;jump if equal ZF=1 if (i == j);if (i == 0);
JNZ/JNE 若不为0则跳转；若不相等则跳转 jump if not zero;jump if not equal ZF=0 if (i != j);if (i != 0);
JS 若为负则跳转 jump if sign SF=1 if (i < 0);
JNS 若为正则跳转 jump if not sign SF=0 if (i > 0);
JP/JPE 若1出现次数为偶数则跳转 jump if Parity (Even) PF=1 (null)
JNP/JPO 若1出现次数为奇数则跳转 jump if not parity (odd) PF=0 (null)
JO 若溢出则跳转 jump if overflow OF=1 (null)
JNO 若无溢出则跳转 jump if not overflow OF=0 (null)
JC/JB/JNAE 若进位则跳转；若低于则跳转；若不高于等于则跳转 jump if carry;jump if below;jump if not above equal CF=1 if (i < j);
JNC/JNB/JAE 若无进位则跳转；若不低于则跳转；若高于等于则跳转； jump if not carry;jump if not below;jump if above equal CF=0 if (i >= j);
JBE/JNA 若低于等于则跳转；若不高于则跳转 jump if below equal;jump if not above ZF=1或CF=1 if (i <= j);
JNBE/JA 若不低于等于则跳转；若高于则跳转 jump if not below equal;jump if above ZF=0或CF=0 if (i > j);
JL/JNGE 若小于则跳转；若不大于等于则跳转 jump if less;jump if not greater equal SF != OF if (si < sj);
JNL/JGE 若不小于则跳转；若大于等于则跳转； jump if not less;jump if greater equal SF = OF if (si >= sj);
JLE/JNG 若小于等于则跳转；若不大于则跳转 jump if less equal;jump if not greater ZF != OF 或 ZF=1 if (si <= sj);
JNLE/JG 若不小于等于则跳转；若大于则跳转 jump if not less equal;jump if greater SF=0F 且 ZF=0 if(si>sj)
