8c31bc704826d46cad65c4d65b4b70de7144205a is the first bad commit commit 8c31bc704826d46cad65c4d65b4b70de7144205a Author: Bryan Cain bryancain3@gmail.com Date: Wed Aug 17 10:01:30 2011 -0500
glsl_to_tgsi: implement ir_unop_logic_not using 1-x
Since our logic values are 0.0 (false) and 1.0 (true), 1.0 - x accurately implements logical not.
This is a port of commit 6ad08989d7c1 to glsl_to_tgsi.

--- Comment #1 from Tom Stellard tstellar@gmail.com 2012-02-13 18:51:03 PST --- This is a r300 compiler bug. Flow control doesn't work very well for vertex shaders at the moment. I have been slowly working on fixing this, but I'm not quite done yet.
