title="RESOLVED FIXED - Unigine Valley regression since radeon/llvm: Run LLVM's instruction combining pass"
href="show_bug.cgi?id=90056">https://bugs.freedesktop.org/show_bug.cgi?id=90056</a>
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

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 -
