--- Comment #3 from Ilia Mirkin <imirkin at alum.mit.edu> ---
A fairer comparison would be

LIBGL_ALWAYS_SOFTWARE=1 LP_NATIVE_VECTOR_WIDTH=128

Since I assume it will otherwise use 256-bit wide vectors on your intel CPU.
But it appears that the rendering is actually incorrect there. My personal
guess is that llvm on arm has some issues, but this is based purely on the fact
that you're seeing misrendering :)

It may be worthwhile to build mesa-git and llvm-svn and see if the issue
persists. (mesa-git should be able to build against the llvm head, while
released mesa probably won't.)
