 Creates a new instance; needed by a fixed-point PhaseMan.

 Invoked if your Phase has additional args.

 Dito, but invoked by Phase::recreate.
virtual bool redirects () const
 If true, Phase::create uses take_resolved().
virtual std::unique_ptr< Phasetake_resolved ()

Detailed Description

Static Argument Transformation.

A recursive Lam whose self-calls merely forward some of its params is split into a wrapper wrap (same signature) and a loop that drops those params; self-calls forwarding all of them become jumps to loop, all others go through wrap. Tail recursion elimination is the special case where the dropped param is the ret var.

Member Function Documentation

◆ analyze()

bool mim::StaticArgOpt::analyze ( )
finalprivatevirtual

Runs the optional pre-analysis on Phase::world, typically to a fixed point, before rewriting begins.

If analysis() is set, this is the natural place to iterate until Phase::todo() becomes false. If no Analysis is needed, simply return false.

Reimplemented from mim::RWBase.
