[Bug 78669] [r600g with -O3] layered-rendering/clear-color-all-types 3d single_level fails

https://bugs.freedesktop.org/show_bug.cgi?id=78669

--- Comment #7 from David Heidelberger (okias) david.heidelberger@ixit.cz --- with -O between -Og, -O0 and -O2 it gives 1:300 - pass:fail Chances for pass are increased by running or turning off any GL app.. for this case I always get one or two "pass".

With CFLAGS="-ggdb -pg -g -Og -gdwarf-2 -gstrict-dwarf" I mostly getting more pass for turning GL app on/off (about 3-4)

Command to test: $ while true; do sleep 0.03 && /projects/piglit/bin/gl-3.2-layered-rendering-clear-color-all-types 3d single_level -fbo -auto | grep pass; done
