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`

use existing analyses.
* `Accurate Garbage Collection with LLVM <GarbageCollection.html>`_
The interfaces source-language compilers should use for compiling GC'd
programs.

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.

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.
* `System Library <SystemLibrary.html>`_
This document describes the LLVM System Library (<tt>lib/System</tt>) 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
* `The LLVM gold plugin <GoldPlugin.html>`_
How to build your programs with link-time optimization on Linux.
