You need to rewrite references to global variables to go through a register. movl _128mm@GOTPCREL(%rip),%rax psubw mm2,(%rax) The easiest way to see the right code to generate is to write C code which accesses a global variable in the same way, compile it with the -S option, and look at the resulting assembly code.
