Shader compilation log

Advanced Lighting Model shader for Second Life fails to compile. When enabled,
the menu waits for a moment then turns the option back off. I attached a log of
the messages printed to the console during shader activation... there seem to
be a lot of complaints about FXAA.

The problem only exists in the RadeonSI driver, not the R600 driver! Until
yesterday I had a Radeon HD 6870 video card (AMD BARTS) and the shader worked
perfectly, now I got a Radeon R7 370 (AMD PITCAIRN) and the problem occurs
since I installed it.
