Description
该问题是怎么引起的？
使用dw/dx 算法，然后开启重计算，会发现重计算执行了两次
重现步骤
只需要dw/dx 开启时，把重计算打开便能复现
报错信息
不会有报错信息，只是性能较差

Research direction
No files or tests are named. Start by locating the dw/dx algorithm and the recomputation path, then reproduce the case with dw/dx and recomputation enabled. Done means the recomputation runs once instead of twice and performance no longer includes the duplicate work.
