            Bug ID: 26200
           Summary: Globalopt drops debuginfo when promoting globals to
                    allocas.
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: Core LLVM classes
          Assignee: unassignedbugs at nondot.org
          Reporter: jonathan at codesourcery.com
                CC: llvm-bugs at lists.llvm.org
    Classification: Unclassified

The underlying issue here is that the DI metadata schema is not sufficiently
rich enough to represent this transformation.

Partial implementation & discussion here: http://reviews.llvm.org/D16209
(before I knew how much finagling would be needed).
