[LLVMdev] line number information

Thanks for your help. I took a look at
http://llvm.org/docs/SourceLevelDebugging.html and it seems like this
doesn't give you much in the way of line number information. If you know
what source line you are interested in then you can set a breakpoint, but
suppose you want to know the line number in the source code for some
arbitrary bytecode instruction. In my particular case, I have a pass that
finds bytecode instructions that represent indirect calls, now I want to
find out what line number and source file that indirect call came from. Is
there currently not a way to get this type of information? Thanks again.
