[llvm-dev] [LLVMdev] DebugInfo from LLVM Instruction

[Simone Atzeni via llvm-dev]

Hi all,

I used to extract the debug information from an LLVM Instruction in the following way:

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();
}

As specified also at http://llvm.org/docs/SourceLevelDebugging.html <http://llvm.org/docs/SourceLevelDebugging.html>

However, looks like that the instruction " DILocation Loc(N);” is not valid anymore,
Since the DILocation class is changed. 
Is that right?
How can I extract debug info (line, filename, etc.) from an instruction?

Thanks.
Best Regards,
Simone
