-# LLRT: Low Level Runtime
-
-## Why?
-
-The same reason for LLVM compiler-rt.  LLVM generates libgcc symbols, such as
-__divdi3 for 64-bit division on 32-bit platform.  They are not also available.
-We need to ship compiler-rt but it is not Windows ready.
-This subproject aims to provide a small portable subset of compiler-rt.
-Start small and add only the things we really needed.
-Performance is not crucial but should not be terrible.
-Functionality and usefullness should be more important than performance.
-
-## Developer Instructions
-
-LLRT implements some functionalities in compiler-rt in ANSI C.
-The C files are compiled using clang to produce LLVM IR which are shipped.
-The IR files are committed in the repository.
-So, remember to build the IR files commit them after modifying the C files.
-
-## Build Requirement
-
-- Make
-- Clang
-- Python

-# README
-
-This is a reimplementation of the LLVM binding, aiming to provide a more 
-familiar interface to the C++ API whenever possible.
-
-The implementation uses a custom DSL in python to describe the interface. 
-The DSL serves as input to *gen/gen.py* for generation of the .cpp and .py files 
-for the actual binding.
-
-# How to Add New Class
-
-Let's use the `llvm::Module` as an example because it should be one of the most
-familiar class in LLVM.
-
-Reference code in https://github.com/llvmpy/llvmpy/blob/master/llvmpy/src/Module.py
-and see LLVM documentation at http://llvm.org/docs/doxygen/html/classllvm_1_1Module.html
-
-1) Import binding helpers
-
-```python
-from binding import *
-# Yes, it is bad practice to import star.
-# I will fix it one day.
-```
-
-2) Import LLVM namespace
-
-```python
-from .namespace import llvm
-```
-
-3) Declare the class
-
-```python
-Module = llvm.Class()
-```
-
-4) Import all the dependencies for the definition
-
-5) Define the class
-
-```python
-@Module
-class Module:
-    ...
-```
-
-## Inside the definition...
-
-5.1) Use the ``_include_`` attribute to add include files.
-
-5.2) Use ``Enum`` to create an enumerator type.
-
-5.3) Make constructor 
-
-Not every class needs to have a binding for the constructor.
-Only add things that will be used.
-
-```python
-new = Constructor(cast(str, StringRef), ref(LLVMContext))
-```
-
-The constructor must be named as "new".
-
-The args to ``Constructor`` are parameters of the signature.
-The first parameter means cast Python string to a StringRef.
-The second parameter means pass LLVMContext object as a value reference.
-
-5.4) Make destructor
-
-Not every class needs to have a binding for the destructor.
-Only add things that will be used.
-If it is always owned by another object, it usually does not need to have one.
-
-```python
-delete = Destructor()
-```
-
-The destructor must be named as "delete".
-
-5.5) Add Simple Methods
-
-```python
-getFunction = Method(ptr(Function), cast(str, StringRef))
-```
-
-The first arg is the return type: a ponter to Function.
-The rest of the args are for the parameters.
-
-Note: ``cast(fromtype, totype)`` can be used as return-type as well.
-In that case, the ``fromtype`` will usually refer to a LLVM object
-and the ``totype`` will refer to the Python object.
-
-5.6) Add custom methods defined in C++
-
-The ``list_functions`` is created as a ``CustomMethod``.
-
-```python
-list_functions = CustomMethod('Module_list_functions', PyObjectPtr)
-```
-
-The first arg is the name that appears in C++.
-The second argument is the return-type.
-The rest of the arguments are parameters.
-
-The definition of ``Module_list_functions`` is located in 
-"include/llvm_binding/extra.h".
-
-5.7) Add custom python method
-
-One can also add custom methods in Python, e.g. ``__str__``.
-
-```python
-@CustomPythonMethod
-def __str__(self):
-    from llvmpy import extra
-    os = extra.make_raw_ostream_for_printing()
-    self.print_(os, None)
-    return os.str()
-```
-
-The body of ``__str__`` is directly copied to the Python output file.
-Thus, it can't reference to anything in current file scope.
