That crossed my mind a few minutes later. : ) If you're interested, PRE.cpp existed last at r25315. It calculates the "availability frontier" which is probably what you're looking for. I suggest, however, that you try coming up with another solution instead. You might consider using -mergereturn. H. On Wed, Nov 13, 2013 at 2:13 AM, Bin Tzeng <bintzeng at gmail.com> wrote:...
