778: PittNullCode is slow to compile. Frank is not sure what to do about it. According to Josef there is a constraint function that is slow. Josef usually does not compile this file. Ask Bela and or Roland about suggestions about what to do. Check if newer Intel compilers compiles it faster. Is it an option to remove it from ET.
If I recall correctly, then this function is written in a whole-array style. Rewriting this with explicit index operations and surrounding it by a loop should improve compile time significantly.
Roland already did this, and saw a speed improvement (see the ticket). I believe this improvement only helped with older compilers though. With 14.0.0, the file still takes 20 minutes to compile.
