I just built Mesa master using this llvm 9 snapshot: http://apt.llvm.org/unstable/pool/main/l/llvm-toolchain-snapshot/llvm-9-dev_9~svn364485-1~exp1%2b0~20190626222339.2586~1.gbp8282b6_amd64.deb The Witcher 3 in Wine+dxvk started hanging (causing GPU reset). Hardware: Sapphire Pulse AMD Vega 56. With llvm 8, and it's not hanging.
I think this was an issue with the linking for tessellation being changed in LLVM, which was fixed by the following radv MR: https://gitlab.freedesktop.org/mesa/mesa/merge_requests/1216 Given the age, I'm closing. Feel free to reopen if still occurring.
