Andrei's idea could be valid as an optimization when the compiler can see that all the operations can be performed with SIMD ops. In this particular case: if test1a(a) is inlined. But it can't work if the float[4] value crosses a function's boundary.
In this case it's the exact contrary: the float[4] and the operation are both local to the function. So it all depends on the inlining of the dummy functions that follows. No?
