From 12a66d91f6b0beff123fb6fd8a4f3c3796379532 Mon Sep 17 00:00:00 2001 From: Topi Pohjolainen Date: Thu, 25 Jun 2015 14:35:26 +0300 Subject: [PATCH] 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.
