Author: Topi Pohjolainen <[email protected]> Date: Thu Jun 25 14:35:26 2015 +0300 i965: Only write program to cache when it doesn't exist yet Current logic re-writes the same data when existing data is found. Not that this actually matters at the moment in practice, the contraint for finding matching data is too severe to ever allow data to be shared between two items in the cache.
