Reduced testcase:
register struct CPUX86State *env asm("ebp");
register unsigned long T0 asm("ebx");
register unsigned long T1 asm("esi");
register unsigned long T2 asm("edi");
extern int __op_param1, __op_param2, __op_param3;
void op_movq(void)
{
unsigned long long*d, *s;
d = (unsigned long long *)((char *)env + ((long)(&__op_param1)));
s = (unsigned long long *)((char *)env + ((long)(&__op_param2)));
*d = *s;
}

Hmm, you are starving the RA, so in a way this is not a bug. There is a dup of
this bug too.
