[LLVMdev] Name of Function's original module during link-time optimization

[Bram Adams]

Hi,

During link-time optimization using llvm-ld, I occasionally need to  
find the name/ID of the original module/bytecode file a Function  
belonged to. In order to do this I added a nameOfPreviousModule- 
attribute to Function and some getters/setters (see attached patch).  
However, I can't find out how to read in the ModuleID of a Module  
during bytecode loading in lib/bytecode/Reader/Reader.cpp.

How can one do this? Is there another (better) way to accomplish what  
I intend to do here (without extra attribute e.g.)?

Kind regards,
