Apart from not having the platform to reproduce this, I am
also lacking the skills to fix operand constraints in
the inline assembly, and I think this is where the problem
It seems to come down to the constraints in the QPEL_CAVSVNUM
macro in the libavcodec/x86/cavsdsp_mmx.c file.
I would be grateful for any comments about them.
