C++ (Cpp) SymbolRef::getOriginRegion Examples

Example #1

File: MoveChecker.cpp Project: LegalizeAdulthood/clang

static const MemRegion *unwrapRValueReferenceIndirection(const MemRegion *MR) {
  if (const auto *SR = dyn_cast_or_null<SymbolicRegion>(MR)) {
    SymbolRef Sym = SR->getSymbol();
    if (Sym->getType()->isRValueReferenceType())
      if (const MemRegion *OriginMR = Sym->getOriginRegion())
        return OriginMR;
  }
  return MR;
}

Example #2

File: RetainCountDiagnostics.cpp Project: FreeBSDFoundation/freebsd

void RefLeakReport::deriveParamLocation(CheckerContext &Ctx, SymbolRef sym) {
  const SourceManager& SMgr = Ctx.getSourceManager();

  if (!sym->getOriginRegion())
    return;

  auto *Region = dyn_cast<DeclRegion>(sym->getOriginRegion());
  if (Region) {
    const Decl *PDecl = Region->getDecl();
    if (PDecl && isa<ParmVarDecl>(PDecl)) {
      PathDiagnosticLocation ParamLocation =
          PathDiagnosticLocation::create(PDecl, SMgr);
      Location = ParamLocation;
      UniqueingLocation = ParamLocation;
      UniqueingDecl = Ctx.getLocationContext()->getDecl();
    }
