Sorry, dep_dp_76(D) + 8B corresponds to DbitsLeft. But again, both places where
address is taken don't cast the pointer or so:

benchspec/CPU/525.x264_r/src/ldecod_src/biaridecod.c:  int *DbitsLeft =
&dep->DbitsLeft;
benchspec/CPU/525.x264_r/src/ldecod_src/biaridecod.c:   int *DbitsLeft =
&dep->DbitsLeft;
