M4F has FPU option implemented.

I use floating point instuctions, so FPU has to be emulated by qemu. Surfing in qemu source code it seems to me that the FPU extensions are not implemented for cortex M4. Can you confirm or (hopefully) deny this?

best regards

Which command line parameters?
You can query the list of supported CPUs with "-cpu ?" like this:

qemu-system-aarch64 -M virt -cpu ?

There seems to be a "cortex-m4" available ... is that close enough to
the "M4F"?
