[LLVMdev] Extending AsmPrinterHandler

[Eric Christopher]

You could write the debug information you want into just a section in
memory and have your external/alternate/other process/thread/etc pick it up
on the other end? I don't see how the extra info you want to send is
important here, you'd just be extending the existing debug support. Or I'm
missing something at which point I'm not sure which additional questions to
ask :)
