With -Og is perfectly fine. Kernel: 3.12.18 Mesa: git (1646f4d0fb0efec04dce62b6dd4d974206acc8ac) Card: Radeon HD 6550 (3870K APU)
Is this only an issue with -O3?
nevermind.
I think the result of this test is random. It's also random on radeonsi.
it's random with -O3 or just random? if you want some more testing on 6550D, let me know
I always compile with -O2 and the test result is random pass/fail.
try with -O3, then it's permanently PIGLIT: {'result': 'fail' } I tried: while true; do /home/okias/projects/piglit/bin/gl-3.2-layered-rendering-clear-color-all-types 3d single_level -fbo -auto | grep result; done and always fail
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
