[cfe-dev] Line and Column from clang-tidy

Take a look at SourceManager methods like getSpellingLineNumber

In a clang-tidy check, you can write something along the lines:
  const SourceManager &SM = *Result.SourceManager;
  SourceLocation Loc = ...;
  bool Invalid = false;
  unsigned LineNo = SM.getSpellingLineNumber(Loc, &Invalid);
  unsigned ColNo = SM.getSpellingColumnNumber(Loc, &Invalid);

Cheers,
