I have a small problem. xcode 4.4.1 do not accept those 2 instructions anymore
vqrshrn.u16 d0, q1, #0 vshrn.u16 d6, q3, #0
The problem comes from the immédiat value (#0)
I've had to replace those line by
vmovn.u16 d0, q1 vmovn.u16 d6, q3
But if vmovn is equivalent to vshrn, it is not really the same thing for vqrshrn !!!
I wonder if it could be a missing compilation option !
