From 56705cd36bf48d5050ac9ec10d91fd097a577f42 Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Thu, 20 Sep 2012 14:27:29 -0700 Subject: mesa: Don't flatten IF statements by default. MaxIfDepth of 0 means "flatten all the time", not "never flatten". This is only desirable on hardware that can't support control flow; software rasterization and most hardware drivers want this. This alters behavior for swrast as well as i915. Tested on i915. NOTE: This is a candidate for stable release branches.
