    When I build spec2017 648.exchange2_r using flang-new, I get an error
```shell

```

exchange2.fppized.f90 as follows：
[exchange2.fppized.f90.txt](https://github.com/llvm/llvm-project/files/9368068/exchange2.fppized.f90.txt)

It seems than flang-new is not very mature，right？
How can I build classic fortran using newest clang 16？
