The `ifx` compiler returns the following warnings:
```
ifx: command line warning #10148: option '/Qunroll-aggressive' not supported
ifx: command line warning #10148: option '/Qinline-forceinline' not supported
```
But the compiler reference does not forbid using the above flags in the ifx compiler.
Are these warnings credible? If so, are there equivalent flags for the `ifx`?

According to the Fortran Developer Guide and reference /Qunroll-aggressive is ifort only.
I see the same for /Qinline-forceinline., ifort only.
Do you need those options with ifx for performance? LLVM is a whole new backend. What does the optimization report tell you?
