  1class LLVM_INTEGER_TYPE
  2-- Integer representation type in LLVM.
  3
  4-- It represents integer types, including the built-in 1-bit. 8-bit,
  5-- 16-bit, 32-bit and 64-bit.
  6
  7-- The underlying C++ function to get or create an IntegerType pointer is
  8-- "const IntegerType *IntegerType::get ( LLVMContext & C, unsigned
  9-- NumBits )" and is a static method and it's the primary way of
 10-- constructing an IntegerType. If an IntegerType with the same NumBits
 11-- value was previously instantiated, that instance will be returned.
 12-- Otherwise a new one will be created. Only one instance with a given
 13-- NumBits value is ever created.
