类似地,目前的优化实现也不支持指针参数的单元类型为数组的情况(isArrayTy()),以及指针参数的单元类型为结构体(isStructTy())且结构体中有多于一种数据类型的情况(getNumContainedTypes()),这些都被视为不合格的use。 如果找到指针参数的合格use(如本例中的指针参数%r),则该指针参数有可能被优化为结构返回,将其...

pointer type - 指针类型, 指向某个内存对象, 注意没有void *, 而使用i8 *代替 array type - 数组类型, 包含元素类型与个数 label type - 标识代码块, 类似于汇编的label token type - 与指令相关的特殊值类型, 比如phi / select等 struct type - ...
