Analyze Hook for the PassMan
Invoked after the PassMan has finished Pass::rewriteing PassMan::curr_mut to analyze the Def. Will only be invoked if Pass::fixed_point() yields true - which will be the case for FPPasses. Returns mim::No_Undo or the state to roll back to.

Detailed Description

All Passes that want to be registered in the PassMan must implement this interface.

• Inherit from RWPass if your pass does not need state and a fixed-point iteration.
• Inherit from FPPass if you do need state and a fixed-point.
• If you do not rely on interaction between different Passes, consider using Phase instead.

virtual void mim::Pass::dealloc ( void * )

inlineprivatevirtual

Destructor.

Reimplemented in mim::FPPass< P, M >, mim::FPPass< BetaRed, Def >, mim::FPPass< CopyProp, Lam >, mim::FPPass< EtaExp, Lam >, mim::FPPass< EtaRed, Def >, mim::FPPass< LowerTypedClosPrep, Lam >, mim::FPPass< SSAConstr, Lam >, and mim::FPPass< TailRecElim, Lam >.

Definition at line 94 of file pass.h.

enter()

virtual void mim::Pass::enter ( )

inlinevirtual

Invoked just before Pass::rewriteing PassMan::curr_mut's body.

Note

This is invoked when seeing the inside of a mutable the first time. This is often too late, as you usually want to do something when you see a mutable the first time from the outside. This means that this PassMan::curr_mut has already been encountered elsewhere. Otherwise, we wouldn't have seen PassMan::curr_mut to begin with (unless it is Def::is_external).

Reimplemented in mim::plug::clos::Clos2SJLJ, mim::plug::clos::ClosConvPrep, mim::plug::compile::DebugPrint, mim::plug::compile::InternalCleanup, mim::plug::direct::CPS2DS, mim::plug::mem::Reshape, mim::plug::mem::SSAConstr, and mim::RetWrap.

virtual bool mim::Pass::inspect ( ) const

Should the PassMan even consider this pass?
