<pre>SPEC CPU 2016 1.1 444.namd currently fails with Polly (-O3 -mllvm -polly -mllvm
-polly-process-unprofitable). Trying to bisect the commit causing it, I could
go back to r288174 where it still fails. This is the first commit where Polly
compiles with current LLVM/Clang trunk (r297414)
This might be something uncovered by an LLVM change. My next step would be to
bisect with <a href="https://github.com/llvm-project/llvm-project">https://github.com/llvm-project/llvm-project</a> .
