[LLVMdev] source line number for instruction

[Guoliang Jin]

  Hi,

I found the following at 
http://llvm.org/docs/SourceLevelDebugging.html#ccxx_frontend:

  if (MDNode *N = I->getMetadata("dbg")) {  // Here I is an LLVM instruction
    DILocation Loc(N);                      // DILocation is in DebugInfo.h
    unsigned Line = Loc.getLineNumber();
    StringRef File = Loc.getFilename();
    StringRef Dir = Loc.getDirectory();
  }

Does this also work for release 2.7? I did not see the same thing at the 
documentation for release 2.7.

Thanks,
Guoliang
