Class Summary

DeepInliner	DeepInliner contains the code responsible with inlining a set of InlineChains.
InlineChain	InlineChain models an arbitrary-length call path that needs to be inlined.
OneLevelInliner	OneLevelInliner contains the code that inlines a single CALL instruction.

Package harpoon.Analysis.Quads.DeepInliner Description

This package contains code that perform inlining. There are two classes that contain static methods that perform inlining:

• DeepInliner - inlines sets of arbitrary-length call paths. Each call path is modeled by a InlineChain object.
• OneLevelInliner - inlines call paths of length 1. This class is used internally by DeepInliner, but can also be used independently.

Both classes perform inlining by mutating the caller code from a caching code factory. A more elegant alternative would have been to construct an HCodeFactory that produces the transformed code on demand. Still, the complications attached to the arbitrary-length inlining prevented us from such an elegant solution; the current, simple solution also has the advantage of being easier to debug.
