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

Thanks. I will try it.> >> I did not see the same thing at the documentation for release 2.7. > > The link you cited is the documentation for release 2.7.I thought it was documentation for mainline LLVM. Also I thought the documentation for release 2.7 was http://llvm.org/releases/2.7/docs/SourceLevelDebugging.html which does not mention the same example. Guoliang
