##### LLVM (`flang-new`)
Testing Fiats with LLVM `flang-new` version 20 or later with the following command should report that all tests pass:
```
fpm test --compiler flang-new --flag "-O3"
fpm test --compiler flang-new --flag "-cpp -O3"

With LLVM 19, add `-mmlir -allow-assumed-rank` to the `--flag` argument.
With LLVM 21, it should be possible to automatically parallelize batch inferences on central processing units (CPUs).

This capability is under development with the goal to facilitate automatic GPU offloading via the following command:
