Detailed Description

This file describes how to lower LLVM code to machine code. This has two main components:

1. Which ValueTypes are natively supported by the target.
2. Which operations are supported for supported ValueTypes.
3. Cost thresholds for alternative implementations of certain operations.

In addition it has a few other components, like information about FP immediates.
