From 01f9fdc4acd28cc4630a3c71f2d007373f4d979c Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Mon, 19 Sep 2011 23:47:56 -0700 Subject: [PATCH] i965: Set MaxIfDepth to UINT_MAX on Gen6+ and 16 on prior generations. Commit 488fe51cf823ccd137c667f1e92dd86f8323b723 converted the EmitNoIfs flag to MaxIfDepth, an unsigned integer saying "flatten if-statements nested beyond this depth." Unfortunately, i965 left this initialized to 0, which made ir_to_mesa attempt to flatten all if-statements. We didn't notice right away because we usually throw away ir_to_mesa's code in favor of the native VS and FS backends...but this still creates a lot of unnecessary work.
