Unlike valley I thought heaven 4.0 wasn't affected by above as it runs and looks OK.
There is however an issue, again "fixed" by reverting mesa commit
commit c6d79ed289a75f13c65f011be870f7e43a0fedc7 Author: Tom Stellard thomas.stellard@amd.com Date: Fri Apr 10 17:07:16 2015 +0000
radeon/llvm: Run LLVM's instruction combining pass
This issue is thousands of lines of logging like below.
This happens with or without the llvm fix in the valley bug.
Will attach R600_DEBUG=ps,vs,gs with and without above mesa commit reverted. The debug logs were done with todays llvm,mesa so the valley fix in in llvm.
The errors -
