            Bug ID: 32043
           Summary: LSR takes a long time for the testcase
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: Scalar Optimizations
          Assignee: unassignedb...@nondot.org
          Reporter: w...@google.com
                CC: llvm-bugs@lists.llvm.org

For the testcase attached, at least since r290782 (not saying r290782 is the
culprit. Just earlier version I randomly picked cannot process the IR
correctly), we have the problem below:

llc < test-renamed.ll executed forever. 

The problem was paper covered by rL294814 for a short time and then exposed by
rL295378 again.
