Detailed Description

Rewrites the RWPhase::old_world into the RWPhase::new_world and swaps them afterwards.

This will destroy RWPhase::old_world leaving RWPhase::new_world which will be created here as the current World to work with. This Phase will recursively Rewriter::rewrite

  1. all (old) World::annexes() (during which RWPhase::is_bootstrapping is true), and then
  2. all (old) World::externals() (during which RWPhase::is_bootstrapping is false).
    Note
    You can override Rewriter::rewrite, Rewriter::rewrite_imm, Rewriter::rewrite_mut, etc.

Member Function Documentation

◆ analyze()

You can do an optional fixed-point loop on the RWPhase::old_world before rewriting.

Note
If you don't need a fixed-point, just return false after the first run of analyze.
