--- Comment #6 from Luya Tshimbalanga <luya_tfz(a)thefinalzone.net> ---
I confirm the bug which is caused by eithr LLVM 11.0 or the driver in Fedora 33
when using either command from comment #0:
- LLVM triggered Diagnostic Handler: Illegal instruction detected: VOP*
instruction violates constant bus restriction
renamable $vgpr4 = V_CNDMASK_B32_e32 32768, killed $vgpr5, implicit killed
$vcc, implicit $exec
LLVM failed to compile shader
radeonsi: can't compile a main shader part

Writing: /tmp/blender.crash.txt
Segmentation fault (core dumped)
It looks like radeonsi cannot compile the shader for some reasons with this
highlight:
radeonsi: can't compile a main shader part
Could you run the current installed Blender via terminal and post the traceback
here? Let know which GPU do you use.
Addiitonally, install this scratch build below from LLVM 9.0 and let know if
the issue still occur.
