示例1: TemplateArgumentLoc

TemplateArgumentLoc

      TemplateArgumentLoc OrigLoc,
      SourceLocation &Ellipsis, Optional<unsigned> &NumExpansions) const {
  const TemplateArgument &Argument = OrigLoc.getArgument();

    // FIXME: We shouldn't ever have to worry about missing
    // type-source info!
    TypeSourceInfo *ExpansionTSInfo = OrigLoc.getTypeSourceInfo();
    if (!ExpansionTSInfo)

    TypeLoc Pattern = Expansion.getPatternLoc();
    NumExpansions = Expansion.getTypePtr()->getNumExpansions();

    // We need to copy the TypeLoc because TemplateArgumentLocs store a
    // TypeSourceInfo.
    // FIXME: Find some way to avoid the copy?
    TypeLocBuilder TLB;
    TLB.pushFullCopy(Pattern);
    TypeSourceInfo *PatternTSInfo =
        TLB.getTypeSourceInfo(Context, Pattern.getType());

    return TemplateArgumentLoc(Pattern, Pattern);
  }

  case TemplateArgument::TemplateExpansion:

    return TemplateArgumentLoc(Argument.getPackExpansionPattern(),
                               OrigLoc.getTemplateQualifierLoc(),
                               OrigLoc.getTemplateNameLoc());

Sema::CheckPackExpansion(TypeSourceInfo *Pattern, SourceLocation EllipsisLoc,
                         Optional<unsigned> NumExpansions) {
  // Create the pack expansion type and source-location information.
  QualType Result = CheckPackExpansion(Pattern->getType(),
                                       Pattern->getTypeLoc().getSourceRange(),
