示例1: OS
LabelDecl *Sema::GetOrCreateMSAsmLabel(StringRef ExternalLabelName,
SourceLocation Location,
bool AlwaysCreate) {
LabelDecl* Label = LookupOrCreateLabel(PP.getIdentifierInfo(ExternalLabelName),
Location);
if (Label->isMSAsmLabel()) {
// If we have previously created this label implicitly, mark it as used.
Label->markUsed(Context);
} else {
// Otherwise, insert it, but only resolve it if we have seen the label itself.
std::string InternalName;
llvm::raw_string_ostream OS(InternalName);
// Create an internal name for the label. The name should not be a valid mangled
// name, and should be unique. We use a dot to make the name an invalid mangled
// name.
OS << "__MSASMLABEL_." << MSAsmLabelNameCounter++ << "__" << ExternalLabelName;
Label->setMSAsmLabel(OS.str());
}
if (AlwaysCreate) {
// The label might have been created implicitly from a previously encountered
// goto statement. So, for both newly created and looked up labels, we mark
// them as resolved.
Label->setMSAsmLabelResolved();
}
// Adjust their location for being able to generate accurate diagnostics.
Label->setLocation(Location);
return Label;
