            Bug ID: 28985
           Summary: Invariant load hoisting causes LNT miscompiles
           Product: Polly
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: Optimizer
          Assignee: polly-dev at googlegroups.com
          Reporter: tobias at grosser.es
                CC: llvm-bugs at lists.llvm.org
    Classification: Unclassified

With 278673 -polly -polly-process-unprofitable LNT shows the following
miscompile: 

FAIL: lencod.execution_time

This miscompile disappears when disabling invariant load hoisting. It is not
yet confirmed that this is due to invariant load hoisting. More investigation
is needed to confirm this.
