 This code uses incorrect asm constraints such as 
 
   __asm__ __volatile__ ("movq %%mm3, %0" : "=X" (*dst_2) : );
 
 You are wanting to describe a memory operand, and so should
 have used "=m" instead of "=X".  The later means "any pattern
 whatsoever", so the optimizer is free to create any old complex
 expression that it likes.  We later abort trying to interpret
 this as an address.
 
 It's true that the compiler should not abort even on illegal
 input, but it is not clear how to fix this cleanly.  I'm making
 this low priority, to be handled sometime after gcc 3.0.
