What's the best way to load 2 unaligned 64-bit values into an sse register with SSSE3?

There are 2 pointers to 2 unaligned 8 byte chunks to be loaded into an xmm register. If possible, using intrinsics. And if possible, without using an auxiliary register. Without pins开发者_开发问答rd.[详细]

What is the 4-way SIMD version of float selection on OSX Accelerate framework?

Using the Accelerate framework from OSX, you get access to 4-way SIMD functionality where you can operate on vector floats, vector ints and vector bools. It gives you 4-way divisions e.g. and also 4-w[详细]
