Unfortunately things aren't that simple, you need a pre-loop and a post-loop. That asm block can process only aligned values in groups of 8 floats. So if you have an unaligned array of N items, that starts and ends before and after a block of processable items, you need to process both head and tail separately. a floats: ** **** **** **** **** *** Loop blocks: xxxxxxxxx xxxxxxxxx xxxxxxxxx xxxxxxxxx 16b aligned: ____ ____ ____ ____ ____ ____ ____ ____ if you don't understand still, I can create an example.
