Yes.

No. FPU emulation requires no special compile-time options. The
whole idea is that it runs the same code as native FP.
In contrast, soft-float generates inline subroutine calls for all
floating-point operations.
ok, I get it. So, is there a way to add fpu emulation emulation to my
platform without having to change anything to my native binary code ?
