flags to use to enable FPU on STM32H5 MCUs

[HPhar.1]

In this document it's stated that STM32H5 devices implements the FPv5 floating-point extensions.
From there, how do I know the proper flags to pass to gcc to enable the FPU?
 -mfpu=fpv5-sp-d16
 -mfpu=fpv5-d16

other ?

You are using...CubeIDE ? ( no info given)

in menu -> project -> properties :

->  -mfpu=fpv5-sp-d16 -mfloat-abi=hard

Perfect thank you. I'm having trouble installing CubeIDE on my PC, but thought I would easily find the information somewhere. I Accept the Solution but I would like to know if this is documented somewhere.
