C++ (Cpp) DIDescriptor::isLexicalBlockFile Examples

Example #1

File: LexicalScopes.cpp Project: 32bitmicro/llvm

/// findLexicalScope - Find lexical scope, either regular or inlined, for the
/// given DebugLoc. Return NULL if not found.

  // The scope that we were created with could have an extra file - which
  // isn't what we care about in this case.
  DIDescriptor D = DIDescriptor(Scope);
  if (D.isLexicalBlockFile())

  if (IA)
    return InlinedLexicalScopeMap.lookup(DebugLoc::getFromDILocation(IA));
