Issues with loading to neon registers above q7

Note: This was originally posted on 29th June 2010 at http://forums.arm.com

Have you seen any issues with vld and registers q8-15?

For some reason, doing a load to registers below q8 work fine, but above q8 the registers don't get set.

For example, the first won't work but the second will.

in this case, r3 contains a pointer to a float array (4 floats)

vld1.32 {d16-d17}, [r3]
vld1.32 {d0-d1}, [r3]

any ideas?
