Aligning data in memory

[Peter Alexander]

I posted this is d.learn, and also on stackoverflow.com with no 
satisfactory answer. Can anyone help me with this?

Is there a way to align data on the stack? In particular, I want to 
create an 16-byte aligned array of floats to load into XMM registers 
using movaps, which is significantly faster than movups.

e.g.

void foo()
{
    float[4] v = [1.0f, 2.0f, 3.0f, 4.0f];
    asm
    {
        movaps XMM0, v; // v must be 16-byte aligned for this to work.
        ...
    }
}
