is one of the following:
-mfpu option overrides the default FPU option implied by the target architecture.
-mfpu=none option selects no FPU. No floating-point instructions or floating-point registers are used.
-mfpuoption is only valid with the
armv8a-arm-none-eabitarget. It is not possible to override the default FPU for the
aarch64-arm-none-eabitarget. However, you can prevent the use of floating-point instructions or floating-point registers for the
aarch64-arm-none-eabitarget with the
The default for the
