Recently I was getting "unsupported call to function get_global_id" so I assumed there was some llvm problem. Turns out if this happens you just need to rebuild libclc for your llvm version. With these patches mandelbulber-opencl sorta works: <a href="https://cgit.freedesktop.org/~funfunctor/mesa/log/?h=clover-image-support-enabled">https://cgit.freedesktop.org/~funfunctor/mesa/log/?h=clover-image-support-enabled</a> When I first tested the patches, I made this Video: <a href="https://www.youtube.com/watch?v=-R-r0CEub74">https://www.youtube.com/watch?v=-R-r0CEub74</a> The rendering actually looks close to how OpenCL from amdgpu-pro renders. Today it sorta works, but looks worse.
