Public Member Functions

Public Member Functions inherited from llvm::InlineAdvisor
	InlineAdvisor (InlineAdvisor &&)=delete
virtual	~InlineAdvisor ()
std::unique_ptr< InlineAdvice >	getAdvice (CallBase &CB, bool MandatoryOnly=false)
	Get an InlineAdvice containing a recommendation on whether to inline or not.
virtual void	onPassEntry (LazyCallGraph::SCC *SCC=nullptr)
	This must be called when the Inliner pass is entered, to allow the InlineAdvisor update internal state, as result of function passes run between Inliner pass runs (for the same module).
virtual void	onPassExit (LazyCallGraph::SCC *SCC=nullptr)
	This must be called when the Inliner pass is exited, as function passes may be run subsequently.
virtual void	print (raw_ostream &OS) const
	Support for printer pass.
const char *	getAnnotatedInlinePassName () const
	NOTE pass name is annotated only when inline advisor constructor provides InlineContext.

Detailed Description

Replay inline advisor that uses optimization remarks from inlining of previous build to guide current inlining.

This is useful for inliner tuning.
