Passing 8 first floats (in register) works.

But stack passed float don't.

Is test16double in TestNative pass or also fail ?

You can compile libraries/clib/native/TestNative.c with -S to see where
float parameters i to p must be and look into
config/powerpc/callmethod_ppc.h to see what's wrong with stack
parameters.
