readable representation and notation.<p>
The LLVM representation aims to be a light weight and low level while being
expressive, type safe, and extensible at the same time. It aims to be a
"universal IR" of sorts, by being at a low enough level that high level ideas
may be cleanly mapped to it (similar to how microprocessors are "universal
IR's", allowing many source languages to be mapped to them). By providing type
safety, LLVM can be used as the target of optimizations: for example, through
pointer analysis, it can be proven that a C automatic variable is never accessed
outside of the current function... allowing it to be promoted to a simple SSA
value instead of a memory location.<p>

The LLVM type system is one of the most important features of the intermediate
representation. Being strongly typed enables a number of optimizations to be
performed on the IR directly, without having to do extra analyses on the side
before the transformation. A strong type system makes it easier to read the
generated code and enables novel analyses and transformations that are not
feasible to perform on normal three address code representations.<p>
