           Summary: SROA fails to propagate debug location annotation
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: All

The testcase s.ll demonstrates the problem.  The phis generated by SROA carry
no debug location MD:

/org/llvm/build$ grep phi s.ll
/org/llvm/build$ ./bin/opt -sroa s.ll -S | grep phi
  %a.addr.0 = phi i32 [ %a, %entry ], [ %0, %for.inc ]
  %i.0 = phi i32 [ 0, %entry ], [ %inc, %for.inc ]
