             Bug #: 15016
           Summary: Assertion failed: (HasInsideLoopSuccs && "Loop block
                    has no in-loop successors!")
           Product: libraries
           Version: trunk
          Platform: Macintosh
        OS/Version: MacOS X
            Status: NEW
          Severity: normal
          Priority: P
         Component: Backend: X86
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: chris.schaf at verizon.net
                CC: llvmbugs at cs.uiuc.edu
    Classification: Unclassified

The following assertion fails when I run "llc -O2 lewp2.bc" on the attached .bc
I'm generating this IR in a common lisp compiler that I'm writing when I don't
use a function-pass-manager because I'm debugging the raw IR.

fry:bug-reports$ llc -O2 lewp2.bc 
Assertion failed: (HasInsideLoopSuccs && "Loop block has no in-loop
successors!"), function verifyLoop, file
line 297.
