The decimal value given in the manual (8 or 9) really needs to be multiplied by

Small performance improvement in generated C code:
...
Instead of unconditionally copying all phi node values into temporaries for
all successor blocks, generate code that will determine what successor
block will be called and then copy only those phi node values needed by
the successor block.
This seems to cut down namd execution time from being 8% higher than GCC to
4% higher than GCC.
