Display flags used when -xHost

Is there a way to report the flags the compiler uses when -xHost is used ???

Reason:

When compiling/running on a AMD Zen3 processor the flag -xHost gives 20% better performance than using -march=znver3. Now I need to perform the compilation on an older CPU but still target the Zen3 for execution. How do I enable the same flags as using -xHost on the Zen3 but from a different CPU?

Using GCC this can be accomplished using:

> gcc -march=native -Q --help=target

Edit:

I should mention I am using the IFX compiler (not ifort).
