From 668cdbe12958247f4a563c362dbf3247de7ccc3f Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Mon, 27 Sep 2010 15:46:51 -0700 Subject: [PATCH] glsl: Fix broadcast_index of lower_variable_index_to_cond_assign. It's trying to get an int smeared across all channels, not trying to get a 1:1 mapping of a subset of a vector's channels. This usually ended up not mattering with ir_to_mesa, since it just smears floats into every chan of a vec4.
