//
// 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.
