3 Floating-point API
6 Kernel code is normally prohibited from using floating-point (FP) registers or
9 userspace floating-point register state.
15 floating-point usage.
20 floating-point registers may be wider than general-purpose registers.
22 Usability of floating-point code within the kernel is architecture-specific.
24 both with and without a floating-point unit, FPU availability must be checked
27 Several architectures implement the generic kernel floating-point API from
31 Build-time API
32 --------------
34 Floating-point code may be built if the option ``ARCH_HAS_KERNEL_FPU_SUPPORT``
42 top-level Makefile as needed. For example::
44     CC_FLAGS_FPU := -mhard-float
48     CC_FLAGS_NO_FPU := -msoft-float
