Description Michael 2017-02-07 05:55:17 UTC 
The fast path (L2007) of this function should be called as early as possible.  I don't fully understand the semantics of the function, but is this fast path condition dependent on all the conditional branches before it?  The branches seem poorly structured regardless (lots of redundant conditions).
