# 不支持__builtin_longjmp/__builtin_setjmp

#### 错误信息

```
error: __builtin_longjmp is not supported for the current target 
  __builtin_longjmp (buf, 1); 
  ^~~~~~~~~~~~~~~~~~~~~~~~~~ 
error: __builtin_setjmp is not supported for the current target 
  int r = __builtin_setjmp (buf); 
          ^~~~~~~~~~~~~~~~~~~~~~
```


#### 问题介绍

当前AArch64后端不支持内置函数 __builtin_longjmp和__builtin_setjmp。


#### 解决方案

- 使用标准库中的setjmp/longjmp；
- 后续支持。
