TODO

+
    +
  1. llvm/include/llvm/Type.def: + add enum for the type
    2. + +
  2. llvm/include/llvm/Type.h: + add ID number for the new type; add a forward declaration of the type also
    3. + +
  3. llvm/include/llvm/DerivedType.h: + add new class to represent new class in the hierarchy; add forward + declaration to the TypeMap value type
    4. + +
  4. llvm/lib/VMCore/Type.cpp: + add support for derived type to: + std::string getTypeDescription(const Type &Ty, + std::vector &TypeStack) + bool TypesEqual(const Type* Ty, const Type *Ty2, + std::map & EqTypes) + add necessary member functions for type, and factory + methods
    5. + +
  5. llvm/lib/AsmReader/Lexer.l: + add ability to parse in the type from text assembly
    6. + +
  6. llvm/lib/ByteCode/Writer/Writer.cpp: + modify void BytecodeWriter::outputType(const Type *T) to + serialize your type
    7. + +
  7. llvm/lib/ByteCode/Reader/Reader.cpp: + modify const Type *BytecodeReader::ParseType() to + read your data type
    8. + +
  8. llvm/lib/VMCore/AsmWriter.cpp: + modify void calcTypeName(const Type *Ty, + std::vector &TypeStack, + std::map &TypeNames, + std::string & Result) + to output the new derived type +
