Interesting, this suggests a bug in the LLVM WQM stuff. Anyway, it makes
sense for now.
Or more likely: v_interp is executed after KILL, which breaks WQM.
That's only relevant for derivative calculations, though, and I thought
those were undefined in GLSL after (non-uniform) KILL? Or is something
(LLVM? GLSL compiler copy-propagation?) too eager in sinking the place
where inputs are loaded?
