示例1: parseControlImm

static void parseControlImm(CursorState* cursor,Name& outBranchTargetName,ControlStructureImm& imm)
{
	tryParseName(cursor,outBranchTargetName);
	cursor->functionState->labelDisassemblyNames.push_back(outBranchTargetName.getString());
	
	FunctionType functionType;
	
	// For backward compatibility, handle a naked result type.
	ValueType singleResultType;
	if(tryParseValueType(cursor, singleResultType))
	{
		functionType = FunctionType(TypeTuple(singleResultType));
	}
	else
	{
		// Parse the callee type, as a reference or explicit declaration.
		const Token* firstTypeToken = cursor->nextToken;
		std::vector<std::string> paramDisassemblyNames;
		NameToIndexMap paramNameToIndexMap;
		const UnresolvedFunctionType unresolvedFunctionType = parseFunctionTypeRefAndOrDecl(
			cursor,
			paramNameToIndexMap,
			paramDisassemblyNames);
		
		// Disallow named parameters.
		if(paramNameToIndexMap.size())
		{
			auto paramNameIt = paramNameToIndexMap.begin();
			parseErrorf(
				cursor->parseState,
				firstTypeToken,
				"block type declaration may not declare parameter names ($%s)",
				paramNameIt->key.getString().c_str());

		if(!unresolvedFunctionType.reference)
		{
			// If there wasn't a type reference, just use the inline declared params and results.
			functionType = unresolvedFunctionType.explicitType;
		}
		else
		{
			// If there was a type reference, resolve it. This also verifies that if there were also
			// params and/or results declared inline that they match the resolved type reference.
			const Uptr referencedFunctionTypeIndex = resolveFunctionType(
				cursor->moduleState,
				unresolvedFunctionType
				).index;
			functionType = cursor->moduleState->module.types[referencedFunctionTypeIndex];
		}
	}

	// Translate the function type into an indexed block type.
	if(functionType.params().size() == 0 && functionType.results().size() == 0)
	{
