函数名称:Returns non-zero if INSN is boostable.* RIP relative instructions are adjusted at copying time in 64 bits mode
函数原型:int can_boost(struct insn *insn, void *addr)
返回类型:int
参数:
| 类型 | 参数 | 名称 |
|---|---|---|
| struct insn * | insn | |
| void * | addr |
| 165 | 如果nbytes恒等于2则返回:st_bit - Determine whether a bit is set*@nr: bit number to test*@addr: Address to start counting from |
| 169 | 如果nbytes不等于1则返回:0 |
| 173 | 如果此条件成立可能性小(为编译器优化)(inat_is_address_size_prefix(attr))则返回:0 |
| 179 | 当: & == 0x60 |
| 181 | 返回:opcode不等于0x62 |
| 182 | 当: & == 0x70 |
| 183 | 返回:0 |
| 184 | 当: & == 0x90 |
| 185 | 返回:opcode不等于0x9a |
| 186 | 当: & == 0xc0 |
| 189 | 当: & == 0xd0 |
| 192 | 当: & == 0xe0 |
| 195 | 当: & == 0xf0 |
| 198 | 默认 |
