Thanks.  I think I see the flow to get the line number from the AST;
using:
clang::CompilerInstance->getASTContext()->getSourceManager()->getInstantiationLineNumber(SourceLocation
Loc)
This takes a SourceLocation.  Can you point in the right direction to
get a SourceLocation for a LLVM bytecode?

Thanks.
