Original behavior restored by the patches below. There's still more work to be done here as i965 has no noise support now. Also, emitting a noise opcode instead of a noise function is just silly. commit 1f3c7d968c4313dbb71bc93306556cc9292d06ef Author: Ian Romanick <ian.d.romanick@intel.com> Date: Wed Sep 1 21:23:52 2010 -0700 glsl2: Implement noise[1234] built-in functions using ir_unop_noise commit 2b70dbfe091af5ae7c788e16275e1af2cb1c284c Author: Ian Romanick <ian.d.romanick@intel.com> Date: Thu Sep 9 15:25:32 2010 -0700 glsl2: Add EmitNoNoise flag, use it to remove noise opcodes commit 547131ac8750acabd030972fc768705c13d19ef7 Author: Ian Romanick <ian.d.romanick@intel.com> Date: Thu Sep 9 15:20:09 2010 -0700 glsl2: Add lowering pass to remove noise opcodes commit 3a5ce85cfa4914711e56c8cf831699242618928e Author: Ian Romanick <ian.d.romanick@intel.com> Date: Wed Sep 1 21:12:10 2010 -0700 glsl2: Add ir_unop_noise I tested it with the newest commit c4046d4fda2fe838659bff99bfa17f57f895a943. It can just run correctly when using LIBGL_ALWAYS_SOFTWARE=1. That is same as bug#29496 Thanks !! |
