Hi Matthias,

thanks for clarification. Maybe I am under a totally wrong impression, but to me is having soft float comparable to not having some special SSE instruction sets with x86. You are missing some instructions, that your code may or may not need, and the compiler replaces them with some other, not hardware accelerated functions. 

To what extend is the handcrafted version better than the one, autotools are providing? 

I really like to learn here. 

Many thanks already!
