I can confirm this issue on my RX 570.

It's happens with mesa compiled with LLVM 7, but not with LLVM 6.

Maybe. I saw this commit is included in Mesa 18.2.2 (I still have 18.2.1 from padoka ppa). Hopefully we'll get an update soon.

Meanwhile I tried to build my own Mesa version (usin meson) but I'm stuck with big "so" files like "libmesa_dri_drivers.so" "libgallium_dri.so"; I expected to get something like "radeonsi_dri.so" ready to be copied on my system and I can't find a lot of documentation on the topic.

It happens Mesa 18.2.2 from padoka are available :) I did the upgrade, and the bug is gone.
