From 1e9cbbb1c40b3df8443877410b5d34a2f12e9ab0 Mon Sep 17 00:00:00 2001 From: Roland Scheidegger Date: Fri, 16 May 2014 22:45:27 +0200 Subject: [PATCH] llvmpipe: do IR counting for shader cache management after optimization. 2ea923cf571235dfe573c35c3f0d90f632bd86d8 had the side effect of IR counting now being done after IR optimization instead of before. Some quick analysis shows that there's roughly 1.5 times more IR instructions before optimization than after, hence the effective shader cache size got quite a bit smaller. Could counter this with an increase of the instruction limit but it probably makes more sense to count them after optimizations, so move that code.
