示例1: TemplateArgumentLoc
TemplateArgumentLoc
TemplateArgumentLoc::getPackExpansionPattern(SourceLocation &Ellipsis,
llvm::Optional<unsigned> &NumExpansions,
ASTContext &Context) const {
assert(Argument.isPackExpansion());
switch (Argument.getKind()) {
case TemplateArgument::Type: {
// FIXME: We shouldn't ever have to worry about missing
// type-source info!
TypeSourceInfo *ExpansionTSInfo = getTypeSourceInfo();
if (!ExpansionTSInfo)
ExpansionTSInfo = Context.getTrivialTypeSourceInfo(
getArgument().getAsType(),
Ellipsis);
PackExpansionTypeLoc Expansion
= cast<PackExpansionTypeLoc>(ExpansionTSInfo->getTypeLoc());
Ellipsis = Expansion.getEllipsisLoc();
TypeLoc Pattern = Expansion.getPatternLoc();
NumExpansions = Expansion.getTypePtr()->getNumExpansions();
// FIXME: This is horrible. We know where the source location data is for
// the pattern, and we have the pattern's type, but we are forced to copy
// them into an ASTContext because TypeSourceInfo bundles them together
// and TemplateArgumentLoc traffics in TypeSourceInfo pointers.
TypeSourceInfo *PatternTSInfo
= Context.CreateTypeSourceInfo(Pattern.getType(),
Pattern.getFullDataSize());
memcpy(PatternTSInfo->getTypeLoc().getOpaqueData(),
Pattern.getOpaqueData(), Pattern.getFullDataSize());
return TemplateArgumentLoc(TemplateArgument(Pattern.getType()),
PatternTSInfo);
}
case TemplateArgument::Expression: {
PackExpansionExpr *Expansion
= cast<PackExpansionExpr>(Argument.getAsExpr());
Expr *Pattern = Expansion->getPattern();
Ellipsis = Expansion->getEllipsisLoc();
NumExpansions = Expansion->getNumExpansions();
return TemplateArgumentLoc(Pattern, Pattern);
}
case TemplateArgument::TemplateExpansion:
