* :doc:`WritingAnLLVMPass`

   Information on how to write LLVM transformations and analyses.

* :doc:`WritingAnLLVMBackend`

   Information on how to write LLVM backends for machine targets.

* :ref:`code_generator`

   The design and implementation of the LLVM code generator.  Useful if you are
   working on retargetting LLVM to a new architecture, designing a new codegen
   pass, or enhancing existing components.
    
* :ref:`tablegen`

   Describes the TableGen tool, which is used heavily by the LLVM code
   generator.
    
* :ref:`alias_analysis`
    
   Information on how to write a new alias analysis implementation or how to
   use existing analyses.

* :doc:`GarbageCollection`

   The interfaces source-language compilers should use for compiling GC'd
   programs.

* :doc:`Source Level Debugging with LLVM <SourceLevelDebugging>`
    
   This document describes the design and philosophy behind the LLVM
   source-level debugger.
    
* :ref:`exception_handling`
    
   This document describes the design and implementation of exception handling
   in LLVM.
    
* :ref:`bugpoint`
    
   Automatic bug finder and test-case reducer description and usage
   information.
    
* :ref:`bitcode_format`
    
   This describes the file format and encoding used for LLVM "bc" files.
    
* :doc:`System Library <SystemLibrary>`
    
   This document describes the LLVM System Library (``lib/System``) and
   how to keep LLVM source code portable
    
* :ref:`lto`
    
   This document describes the interface between LLVM intermodular optimizer
   and the linker and its design
    
* :ref:`gold-plugin`
    
   How to build your programs with link-time optimization on Linux.
    
* :ref:`debugging-jited-code`
    
   How to debug JITed code with GDB.
    
* :ref:`branch_weight`
    
   Provides information about Branch Prediction Information.

* :ref:`segmented_stacks`

   This document describes segmented stacks and how they are used in LLVM.

* `Howto: Implementing LLVM Integrated Assembler`_

   A simple guide for how to implement an LLVM integrated assembler for an
   architecture.
