           Summary: using a ll file as source for debuging info
           Product: tools
           Version: trunk
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: llvm-as
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: alenhar2 at uiuc.edu


either a pass, llc, or llvm-as should be able to insert debugging info relative
the .ll file/llvm representation.

I want to take a bytecode (without debugging symbols), and with some tool
invocation magic add debugging intrinsics.  Obviously I can't get source
language stuff, but I'd like to be able to treat the .ll file as the source
file, inspecting virtual registers in gdb, having sane backtraces, etc.  I don't
see a reason this couldn't be generated from the bytecode.
