Inheritance diagram for mim::RWPhase:

Public Member Functions
bool	is_bootstrapping () const

virtual bool	analyze ()
	You can do an optional fixed-point loop on the RWPhase::old_world before rewriting.

Construction
	RWPhase (World &world, std::string name)

	RWPhase (World &world, flags_t annex)

Rewrite
virtual void	rewrite_annex (flags_t, const Def *)

virtual void	rewrite_external (Def *)

World
Phase::world is the old one. Rewriter::world is the new one. RWPhase::world is deleted to not confuse this.
World &	world ()=delete
	Hides both and forbids direct access.

World &	old_world ()
	Get old Defs from here.

World &	new_world ()
	Create new Defs into this.

Public Member Functions inherited from mim::Phase
	Phase (World &world, std::string name)

	Phase (World &world, flags_t annex)

bool	todo () const

virtual void	run ()
	Entry point and generates some debug output; invokes Phase::start.

	Stage (World &world, std::string name)

	Stage (World &world, flags_t annex)

virtual	~Stage ()=default

virtual std::unique_ptr< Stage >	recreate ()
	Creates a new instance; needed by a fixed-point PhaseMan.

virtual void	apply (const App *)
	Invoked if your Stage has additional args.

virtual void	apply (Stage &)
	Dito, but invoked by Stage::recreate.

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
